What changes have the development of science and technology brought to people's lives?

As soon as I entered the room and put down my schoolbag, I couldn't wait to shout, "Mom, mom, come here quickly. Please tell me what changes technology has brought to us? " Mom said, "Look at you, your eyebrows are burning. Let me tell you slowly. Technology has brought too many changes to people. For example, the earliest invention of gunpowder enabled human beings to split mountains, build bridges and build buildings, which promoted the development of various undertakings and the rapid development of military industry; With the emergence of papermaking and printing, human beings have written conditions, which has promoted people's extensive exchanges in culture, art, language, science and technology, economy and so on; The invention of compass promoted the development of navigation and trade, completed the great geographical discovery, and made mankind know the earth; Nowadays, the scientific and technological achievements of hybrid rice and super rice have increased grain output and solved the problem of feeding the world population; Like Shenzhou 5 and Shenzhou VI, these space shuttles help astronauts land on the moon, explore Mars and travel in space. Satellites provide us with satellite cloud pictures and weather forecasts, and can also relay TV signals; Robots can do many things that humans can't do, such as diving into the deep sea and breaking into the fire to save people; The maglev train is extremely fast, saving people's travel time; People use atomic energy to generate a lot of electricity …

Humans have also invented many things that are useful to us, such as telephones, computers, televisions and so on, which are convenient for people to do some things. For example, telephone: two people are thousands of miles away from Qianshan, but as long as they pick up the receiver and dial a few numbers, they can hear each other's voice and communicate with each other in a few minutes. This is a miracle that the telephone has brought to mankind. It's not enough to have a telephone. Man invented the computer. Computers are better than telephones. The phone can only hear the voice of the other party, while the computer can communicate with words, video conversation and see the other party. If there is a holiday, send an email and the other party will receive it in a few seconds, which can not only save paper, but also let others receive it quickly ... The development of science and technology has improved our living standards and quality of life! "

In the 20th century, human beings invented many useful things, such as telephones, computers, televisions and so on. It is convenient for modern humans to do some things.

Two people are thousands of miles away from Qianshan, but as long as they pick up the phone and dial a few numbers, they can hear each other's voice and communicate with each other in a few minutes. This is a miracle that the telephone has brought to mankind. The telephone has been invented 100 years. In modern society, it has become an important part of people's work and life. For example, if grandparents are sick, just call to remind them what medicine to take or what to pay attention to. In the 20th century, it was the telephone that brought us convenience.

A telephone is not enough. Man invented the computer. Computers are better than telephones. The telephone can only hear the voice of the other party, while the computer can communicate with language. They can also make video calls on the Internet and see each other. If there is a holiday, send an email and the other party will receive it in a few seconds, which can save paper and let others receive it quickly.

The development of science and technology in the 20th century has made our human life more convenient, and it will continue to develop in the future.

Scientific Outlook on Development has brought great changes to the ecological environment in Xinjiang.

The mountains and rivers are beautiful, the sky is high and the clouds are light, and people live in a green home, which is what Xinjiang people have dreamed of for generations. Nowadays, under the guidance of the great strategic thought of building a socialist harmonious society, adhering to the people-oriented principle and establishing the concept of comprehensive, coordinated and sustainable development put forward by the CPC Central Committee with Comrade Hu Jintao as the general secretary, the people of Xinjiang are using their own hands to realize the dream of a green home that has been difficult to realize for thousands of years.

Xinjiang is located in the hinterland of Eurasia, far from the ocean, with little precipitation, and belongs to a typical inland arid desert climate. The area of desertified land accounts for nearly half of the total land area in the whole region, and the oasis area only accounts for 4.3%. Sandstorm disasters occur frequently, and the ecological environment is extremely fragile.

Xinjiang's economy needs to develop, and so does the construction of ecological environment. How to protect the fragile ecological environment in the process of economic development? Only by fully implementing people-oriented, adhering to the sustainable Scientific Outlook on Development, coordinating the relationship between social development and environment, and realizing the fundamental transformation of economic growth mode, can this contradiction be truly solved.

It is precisely because of the establishment of Scientific Outlook on Development and the strong support of the CPC Central Committee that the ecological construction in Xinjiang has entered an unprecedented period of rapid development.

In recent years, Xinjiang has vigorously implemented various ecological construction projects, and the ecological environment has shown an improvement trend. According to remote sensing monitoring, by the end of 2005, the vegetation coverage area in Xinjiang had reached 65438 0093400 square kilometers, accounting for 65.96% of the total area in Xinjiang, which was 65438 05.8% higher than that in 2000. The results of the third desertification and desertification monitoring in Xinjiang show that during the Tenth Five-Year Plan period, the desertified land in Xinjiang decreased by more than1.4000 square kilometers compared with that during the Ninth Five-Year Plan period.

Of course, this is because Xinjiang is in a period of abundant water in history, but it is all kinds of ecological construction projects implemented in Xinjiang that play a decisive role: afforestation, enclosure, ecological management of Tarim River and so on. The implementation of these projects has generally increased the vegetation coverage area in Xinjiang.

The most direct function of increasing vegetation coverage is to prevent wind and fix sand. Compared with the past, during the Tenth Five-Year Plan period, the number of sandstorms in Xinjiang was less, and the scope and degree of influence were also smaller.

Nowadays, the pace of ecological construction in Xinjiang has been greatly accelerated. Take the forestry sector as an example. The tenth five-year plan period is the fastest and best five years in the history of forestry development in Xinjiang. The total afforestation area in Xinjiang has reached more than 22 million mu, which is 3.9 times that during the Ninth Five-Year Plan period. There are 12 prefectures and 8/kloc-0 counties and cities in Xinjiang, and 93% of cultivated land has been effectively protected by forest network. Key forestry projects such as natural forest protection project, returning farmland to forests project, "Three North" shelter forest system construction project, wildlife protection and nature reserve construction project, and fast-growing and high-yield forest base construction project have all achieved rapid development.

The achievements of ecological construction in Xinjiang are manifested in various aspects. Several major sources affecting Xinjiang's ecology have been effectively controlled: Taklimakan Desert, Gurbantunggut Desert and other deserts have achieved increasing results; The comprehensive management of Tahe and Ebinur Lake has also achieved remarkable results. At the same time, all localities are vigorously renovating the local small environment, and gratifying changes have taken place in the urban and rural environments that are most closely related to the lives of ordinary people. In recent years, people can clearly feel that there are more trees and birds around, and some birds that have been extinct for many years are back.
