What does the sacrifice of a real hero tell us from this passage?

First, the overall grasp

On the long road of scientific exploration, every small step of human progress may be at the expense of some of her best children. However, mankind has not stopped because of this, but summed up experiences and lessons, accumulated strength, moved on, and created one new technological miracle after another. Take the American Challenger explosion as an example. Although the space shuttle was instantly reduced to ashes, the soul of the space hero remained in distant space forever, and the whole human space program suffered a major setback, but mankind was not intimidated. Where you fall, you get up. We have seen that since then, more countries and more people have devoted themselves to space exploration, and one space shuttle after another has risen into the blue sky to explore the unknown universe.

1 986 65438+1On the morning of October 28th, at 1 1: 38, the American space shuttle Challenger suddenly exploded about1min 12 seconds after liftoff, with seven astronauts on board. After the explosion, the plane turned into a huge fireball, dragging a long serpentine flame, and then entered the Atlantic Ocean with yellow and white smoke branches. The space shuttle with a cost of $1200 million was sold in an instant. The United States is extremely sad and mourns all over the country; The whole world was also shocked, and leaders of various countries made speeches in succession, expressing their condolences to the families of the victims and the American people. At that time, US President Ronald Reagan made a televised speech to the whole country that night, expressing his condolences to the lost hero and determined to continue exploring the universe. On 65438+1October 3 1 day, a grand commemorative meeting was held in Houston Space Center, at which President Reagan delivered an emotional speech. This article is the speech draft of this speech.

Speech belongs to the category of argumentative writing, but generally it does not emphasize the rigor of reasoning and the logic of thinking. It always inspires people with a certain spirit and touches people with true feelings. This paper has this basic feature.

To grasp this speech as a whole, we should pay attention to the following aspects.

The theme of the speech. The theme of this article can be summarized as follows: mourning the martyrdom of space warriors, praising the spirit of human exploration, and calling on people to turn grief into strength and continue space exploration on the road pioneered by martyrs. Although this speech is about Americans and American affairs, it is about accidents in the space field, but its significance transcends nationalities, countries, ideologies and different scientific fields, rises to the height of all mankind, and embodies the most shining quality of human beings-the spirit of persistent exploration in unknown fields. Thus, the ideas expressed here belong not only to the United States, but also to all mankind.

Emotions implied in speeches and their changing contexts. The feelings expressed by the speaker in his speech include two aspects: grief and strength. From the emotional context, the full text can be divided into two parts, the first part is mainly to express grief, and the second part is mainly to express strength. Grief is caused by the death of the hero, which is a great loss to mankind, the country, relatives and friends. The speaker expressed this grief and condolences everywhere between the lines. However, human beings can't be sad and depressed forever, but should turn grief into strength and continue to move forward in the footsteps of heroes. It should be noted that the two feelings expressed by the speaker are not completely different in the text, but harmonious. More appropriately, the overall emotion given by the whole speech is grief, but it is not just grief. Inspired by the president's words, the grief of the whole people turned into an invisible force. The result of this space tragedy is not frightening, but encouraging the successors to move forward more forcefully.

General-divided into general writing ideas. From the perspective of writing ideas, this paper can be divided into three parts. The first part, the first four paragraphs, expresses the deep sorrow and praise for the hero; The second part, the middle nine paragraphs, recalls several dedicated heroes respectively, hoping to make people remember these "real American heroes" forever; The third part, the last eight paragraphs, calls on the people to turn grief into strength, inherit the unfinished business of heroes and continue to March into space.

The speaker's posture and role orientation. Such a speech is not an official courtesy, nor is it a lofty leader's condescending evaluation and final conclusion of the people under his rule. The speaker has a dual identity in his speech, one is the president who represents the people of the whole country, and the other is as a member of the people. Because he is the president, he should speak on behalf of the people and give the speech universal significance; As a member of the people, he did not put his position higher than others, but looked up to these real heroes with the people. The author grasps the touching details of the heroes' lives, and recalls them one by one, which makes people feel that these heroes are also living ordinary people. The president is very familiar with every astronaut, which is why his speech is touching, approachable and heartfelt, not polite.

A meaningful statement. The speaker can sum up reasonable words from concrete examples in reality, which can make people think repeatedly and get ideological enlightenment. For example, "Heroes are called heroes not because of the language we praise, but because they always practice real life and even give their lives with a high degree of professionalism, self-esteem and a sense of responsibility to persistently explore the magical and wonderful universe." "In the pain, we have realized a far-reaching truth: the road ahead is not smooth, and the whole history of human progress is a history of fighting against all difficulties and obstacles." These words are not only for these space heroes, but also of universal significance, which makes people think deeply and excite.

Second, the problem research

1. When the speaker mentioned the female teacher mcauliffe, why did she say that she "condensed the imagination of the whole country"?

Mcauliffe is a representative of American elected teachers and the first "space teacher" in the world. Her participation in this space voyage is of great significance. She plans to teach two space classes for more than 2.5 million primary and secondary school students in the United States and Canada, and she will also participate in several scientific performances on the space shuttle. What the children didn't expect was bad news. Here, "the imagination of the whole country" can be understood as primary and secondary school students representing the future and hope of the United States.

2. The astronaut died because of the space shuttle crash, but why did the speaker say "this is a story about victory and bravery"?

The history of human exploration of space is originally a history of adventure and a history of bravery. Every time astronauts take off, it means danger, which may never return, but they are not afraid, but they are righteously prepared to sacrifice at any time. In this sense, no matter success or failure, every astronaut who takes off is a winner, a brave man and worth learning.

3. What is the specific connotation of the American spirit advocated by President Reagan? How to treat this spirit?

Pioneering spirit, imagination, heroism, dedication, great courage, trustworthy reputation, indomitable quality, etc.

Don't look at this American spirit with narrow eyes, but stand at a certain height and regard it as the representative of the excellent quality and lofty spirit of all mankind. By extension, as long as it is the essence of human beings, it is not necessary to distinguish nationality, race, country and ideology, but to learn, learn from and absorb.

Practice note

Read the text first, draw sentences that move you, and tell me where the moving power of this article comes from.

Intention: Let students actively explore and grasp the thoughts and feelings of this speech.

When answering questions, different students draw different sentences, which is normal, as long as he gives a little reason to be moved; If students are unmoved, teachers need to guide and explain them properly; Don't stick to the same answer.

The touching thing about this article is that the speaker is emotional, and his words naturally come from the heart, without giving people the feeling of being polite and insincere.

Second, mobilize your knowledge reserves, contact life, and talk about your understanding of the following sentences.

1. Heroes are called heroes not because of the language we praise, but because they always practice real life and even give their lives with a high degree of professionalism, self-esteem and a sense of responsibility to explore the magical universe.

2. In the pain, we realized a far-reaching truth: the future road is not smooth, and the whole history of human progress is a history of struggling with all difficulties and obstacles.

The only comfort we can find is that we know in our hearts that you who are proud of flying so high have now found the destination promised by God for eternal life beyond the stars.

Intention: Guide students to appreciate and understand several wonderful sentences in the text.

Thinking of answering questions: Students can contact other historical events they know to confirm the meaning expressed in the first and second sentences and explain the meaning in their own words; The third question, as long as you say what feelings the author expressed, why did the author say so.

3. Go to the library or use the Internet to find information, learn about the crash of the space shuttle Challenger, and communicate with your classmates.

Intention: Guide students to deeply understand the background materials related to the text, carry out extracurricular Chinese activities, and improve students' comprehensive Chinese ability.

If the conditions are limited, some contents of "related materials" can be provided to students for discussion and exchange, so as to deepen the understanding of the ideological content of the text.

Teaching suggestion

1. This lesson is a self-reading text, and it is recommended to finish one lesson.

Second, please ask physics teachers or students who have expertise in this field to introduce the general situation of space shuttle and manned spacecraft, deepen students' perceptual knowledge, feel the greatness of mankind and the progress of science and technology, and facilitate understanding of the text.

Third, teachers can find relevant newspapers and pictorial, and if possible, they can download and supplement some information from the Internet, so that students can see some pictures, such as the shape of the space shuttle, the burning fireball, the bifurcated flame during the explosion, the aircraft fragments fished out of the Atlantic Ocean, and the photos of mcauliffe, so as to enhance the intuitive effect of teaching and help students understand the text.

Fourth, strengthen the reading of the text. Few speeches express such rich and strong feelings, and few works can directly impact people's hearts in this way. Reading aloud is the best way to appreciate the feelings of a work. On the basis of listening to the recording, the teacher can fully feel the author's mood when he speaks, and even pretend to be the president to read the text.

5. Ask students to extract good sentences from the text and learn to use them.

A biography of Ronald Reagan

1911February 6th, ronald wilson reagan was born in tampico, Illinois (father John Reagan, mother Lena Reagan). He studied in Dixon, a nearby middle school, and then completed his college course part-time at Eureka College. During his college years, he studied economics and sociology, participated in the school football team competition and performed in the school drama club. After graduation, Reagan became a radio sports announcer, and an audition in 1937 won him a performance contract in Hollywood. In the next 20 years, he acted in 53 films.

Ronald Reagan had two children, Maureen and Michael, with his first wife and actress Jane Whitman. 1952, he married the actress Nancy Davis and gave birth to two sons: Patricia Ann and Ronald Piscaux.

As the president of the Motion Picture Association of America, Reagan began to get involved in some sensitive disputes in the film industry. His political views gradually shifted from freedom to conservatism. As a TV host, Reagan often toured the country and gradually became a spokesman for the Conservative Party. 1966 was elected governor of California with leading votes, and 1970 was re-elected.

1980, Reagan was nominated as the Republican presidential candidate. He chose George Bush, a former senator from Texas and American ambassador to the United Nations, as his running mate. At that time, voters suffered from inflation, and several Americans were held hostage in Iran for a year. These eventually defeated the Democratic Party and the Republican Party won the election. Reagan defeated Jimmy Carter by 489 votes to 49 and was elected president.

198165438+1Reagan took office on October 20th. Only 69 days later, he was shot by an assassin, but he soon recovered and began to work. In this dangerous event, Reagan's demeanor and wit greatly enhanced his prestige.

Reagan skillfully dealt with Congress and made it pass a series of laws to stimulate economic growth, curb inflation, increase employment and strengthen national defense. He also began to cut government spending and tax cuts, and defense spending did not deviate from this principle when it caused a deficit.

American national self-confidence recovered from 65438 to 0984, which enabled Reagan and Bush to win the second term with unprecedented votes. Their victory made Democratic candidates Walter Mondale and Geraldine ferraro "rejected".

From 65438 to 0986, Reagan successfully reformed the tax law and cancelled many deductions-exempting millions of low-income people from taxes. At the end of his term, it was the longest peaceful period in American history without economic recession and depression.

2. American Space Shuttle Challenger (Wenyun Li)

Challenger is the second space shuttle developed by the United States. Compared with the first space shuttle Columbia, it has some improvements in structure, materials and equipment: Columbia weighs 75 tons without fuel. The challenger used an improved internal fuel tank and lost 4? 5 tons, so it can carry more goods; The thermal insulation tile was improved and a new type of reinforced silicon tile was adopted. In addition, the astronaut's seat, landing system and dashboard have also been improved.

Due to some technical problems, the maiden voyage of Challenger was postponed from the original launch of1October 20th 1983 65438+ to April 4th-9th 1983. Challenger's maiden voyage accomplished two main tasks: launching a tracking and data relay satellite weighing two and a half tons; Astronauts Storey musgrave and Donald Peterson made the first "spacewalk". They walked out of the cockpit of Challenger and walked in the open cargo hold for nearly four hours in weightlessness. Challenger made the second and third flights in June and August of 1983. On the second flight, Sally Ryder, the first female astronaut in American history, was sent into space. Lieutenant Colonel Bruft, the first black American astronaut, went into space on the third flight. 1On April 29th, 985, the first Chinese-American scientist, Dr. Wang Ganjun, participated in the seventh flight of Challenger, and was responsible for the fluid dynamics research under weightlessness.

1986 65438+1October 28th Japan flight was the 10 flight of Challenger. In the previous flight, "Challenger" had some failures, among which1July 29th, 985 was the most serious one. At that time, shortly after Challenger took off from Florida, the first of the three engines on board suddenly stopped ahead of schedule, and the astronauts started another small engine on the fuselage in time, which made the space shuttle enter low Earth orbit, which was 128 km lower than the original orbit.

Under normal circumstances, after each flight, the space shuttle can be re-launched after two to four weeks of maintenance and can be reused 100 times.

3. Introduction to the flight of American Space Shuttle (Shen Minghe)

The United States decided to develop the space shuttle in 1972. After nine years of development, setbacks and delays, the American space shuttle Columbia was finally launched in April of 198 1, 12. After a flight of 54 hours and 30 minutes, the Columbia returned to the atmosphere as planned on April 14 and landed safely. The successful test flight of the American space shuttle marks a major breakthrough in the American space industry.

From1981April 12 to 1986 12, the American space shuttle * * * made 24 space flights. There are 125 astronauts in this mission. They conducted various space flight tests on four space shuttles: Columbia, Challenger, Discovery and Atlantis. The crew of 125 included not only American female astronauts, black astronauts and China astronauts, but also scientists from Germany, Canada, France, the Netherlands and Mexico and the prince of Saudi Arabia.

The space shuttle has a specific mission for each flight. During the first to fourth flights, the main task is to test the performance and thermal stress of each component. In the future flight, the main tasks are: releasing and maintaining satellites, conducting various scientific experiments and building the skeleton of large space buildings. The space shuttle also carried out special missions, such as carrying out top secret military missions in the 15 flight and releasing various defense system test satellites.

During the 24 flights, the American space shuttle basically completed its scheduled mission, but there were also many failures, some of which were even very serious. For example, during the second test flight, the space shuttle was forced to return early due to the failure of the fuel cell on board. On the fourth flight, two rocket boosters sank into the Atlantic Ocean. On the fifth flight, the spacewalk plan was aborted because of something wrong with the spacesuit. In the flight 16, more than 0/00 heat insulation tiles of/kloc-0 were damaged. When the space shuttle descended, a tire burned out. The laser reflection test in 18 flight failed for the first time, and the second test was successful. During the first 19 launch of the space shuttle, there was a serious danger. One of its three main engines was started only for 5 minutes and 48 seconds due to thermal sensor failure, and was shut down more than 3 minutes earlier. At that time, Challenger had flown 1 12 kilometers above the ground and had not yet entered the orbit. In the history of manned space flight in the United States for more than 20 years, it is the first time that the engine of a manned spacecraft turned off before entering orbit. In the 20th launch, the space shuttle was delayed twice due to thunderstorm and computer failure on board.

1986 65438+1On October 28th, Challenger exploded in the air during the 25th flight of the American space shuttle. This is the first explosion in 56 manned space flights in the United States, and it is also the first time that an American astronaut died in flight.

Four. Supplementary background materials of challenger's death

Among the seven astronauts, there are two women, namely Krista McAuliffe, 37, and Judith Lenico, 36. The most striking thing, of course, is Christa McAuliffe, who is the only one from the private sector among the seven astronauts.

After more than 50 manned flights, NASA decided to carry "civilian" passengers into space President Reagan proposed that the first civilian astronaut should be a teacher. This is undoubtedly a great honor for educators. The news came out, and it took one year 1 1 000 for the teacher to register. After repeated selection, 10 students were selected. Finally, Krista mcauliffe was chosen. After 120 hours of rigorous and arduous training, she rose into space as a civilian representative for the first time. All the teachers are proud of her air travel. Her parents, husband and children came to the scene to see her off.

Forty seconds after the explosion, naisbitt, on behalf of Smith, director of Kennedy Space Center, announced sadly that the space shuttle Challenger had been blown up.

The launch base of the space center is shrouded in extreme grief. At first, many people cheering for the successful launch of Challenger on the viewing platform were relatives of astronauts. When they saw the explosion, they woke up from the "impossible" consternation and burst into tears. The staff of the space base also hugged each other sadly, and crying could not express their feelings at that time.

The saddest people in the audience are the parents of Krista mcauliffe, a female teacher. "God, it's not true!" Grace's mother looked up at the blue sky and burst into tears.

Father corrigan first noticed this unexpected misfortune, and he hugged his wife's shoulder tightly and wept bitterly. The feeling of happiness and pride for my daughter was immediately replaced by the heart-wrenching pain of losing her daughter. Great grief struck the old couple like electricity. They trembled and cried in the cold wind.

Mcauliffe's husband, 9-year-old son and 6-year-old daughter in the stands are also in tears. In an instant, they lost their wives and mothers ... On this day, all the students in mcauliffe's Xiehe Middle School were waiting for their teacher by the TV ... They talked happily about the teacher's historic voyage. When Challenger was launched, the students cheered excitedly and couldn't help applauding their teacher ... However, something unfortunate happened. At first, they shouted almost at the same time: "This is by no means true!"

More than 10,000 primary and secondary school teachers and their students who had competed with mcauliffe for astronaut status also saw this incredible scene on TV. The "space class" is gone, and all the teachers and students are in great sorrow.

When the fragments of Challenger flew into the Atlantic Ocean, US President Ronald Reagan was having a working lunch with his senior aides. Vice President Bush and National Security Adviser poindexter rushed in to tell you the sad news.

President Reagan's first reaction was: "Is that the space shuttle that the female teacher took?"

Bush said seriously, "Yes."

Everyone stopped lunch, stood up, followed President Reagan to the nearest presidential study and turned on the TV to watch the video news of the accident.

At first, the president was "shocked into silence" by the cruel reality, and his face was full of anxiety, anxiety and sadness. Later, Reagan told reporters: "I can't get rid of the image of the families of the victims at that time."

Nancy, Mrs. Reagan, lost her voice and exclaimed, "Oh, my God! This is impossible! "

After the initial consternation, Reagan discussed with congressional leaders and decided to postpone the State of the Union address scheduled for that evening until next Tuesday, and sent Vice President Bush to the Kennedy Space Center in Florida immediately to express condolences to the families of the victims and investigate the cause of the accident. The House of Representatives, which was in session, interrupted the meeting and adjourned. The bell rang in Washington Cathedral in memory of the victims.

Washington was immersed in an unusually solemn atmosphere, without noise and shouting, as if it had entered a white night. The Olympic torch was rekindled in Los Angeles Memorial Stadium to express condolences. Radio stations all over the country broadcast the Stars and Stripes continuously. Trains and ships sounded the alarm, and the stars and stripes on the main buildings were slowly lowered at half mast ... messages of condolences, messages of sympathy, and snowflakes flying here. The White House seems to be crying. President Reagan trudged to his oval office and made a speech in front of the TV camera. His face is blue and his tone is heavy. He made a televised speech to the whole country in an extremely sad voice: "The speech I originally planned to give you tonight is the State of the Union address. However, what happened this morning changed my mind. Nancy and I are deeply saddened by the tragedy that happened on the Challenger. I know that all the people in my country are as sad as I am. "

He expressed his condolences over the unfortunate death of seven astronauts and praised their "courage and courage". They have that special manner and spirit. This spirit will challenge me and I will be happy to meet it. "

He also mentioned their respected teacher, Christa McAuliffe, to primary and middle school students all over the United States. He knows that this dedicated female teacher touches the hearts of children all over the country. He said, "I know it's hard to understand, but painful things like this sometimes happen."

He announced a sad news to the United States and the world:

"Today is a day of mourning and commemoration ..."

The United States has long been plunged into grief. Near noon, people who knew the news almost interrupted all activities. The complicated street suddenly became much colder than usual, and people hurried on without saying a word. Many people stood by the TV, waiting for a detailed report on the disaster. With the bell of mourning, countless people shed tears.

At night, the Empire State Building in New York, which has never been brightly lit, turns off all the lights to show its condolences. This "national disaster" deeply shocked people's hearts.

The United States originally planned to launch 15 space shuttles in 1986, which was "the most important year since the beginning of the space age", but now all failed. The space shuttle Challenger cost the American taxpayer $6,543.8 +0.2 billion, and it went up in smoke with a loud noise.

The three major television networks in the United States-CBS, ABC and NBC-reported the explosion of Challenger in 654381October 28th for more than five hours, and the lost advertising expenses were estimated at nearly ten million dollars.

In such a disaster, the loss of money seems less important. The seven astronauts killed represent the same dream, which is the eternal dream of human beings to explore the unknown world.

It should be said that no one in the world wants this dream to be broken.

So this is not just the American dream, but the dream of all mankind.

This is not only the disaster of the United States, the sorrow of the United States, but the disaster of the world and the sorrow of all mankind.

The world was shocked.
