I am anxious after reading more than 500 words.

& lt& lt stars. Spring water >; & gt I feel more than 500 words after reading it, and I feel anxious about The Stars in Spring.

This is the first modern poem that I have read completely, and it is also the first time that I have read Bing Xin's works, and it is the first time that I have read this touching masterpiece "Spring among the Stars". After reading it, I suddenly felt a feeling I had never felt before.

This article was written by Bing Xin, a famous writer in China, whose name I have heard since I was a child. When I was a child, my family told me the story of grandma Bing Xin every day, but I never had a chance to see her works. At that time, I only knew what ancient poetry was, and I didn't know the difference between the rhythm of modern poetry and ancient poetry. Once, I came across the article "Stars in Spring Water" and realized that modern poetry is more vivid, catchy and interesting than ancient poetry. Unconsciously, I fell in love with modern poetry. If you don't believe me, listen to me about the article "Spring Water Stars"!

Let's take a look at this passage first: the stars are twinkling-how can we hear their conversation in the dark blue sky?

In silence, in the twilight, they deeply praised each other. In just a few words, it outlines a beautiful, aesthetical, natural and harmonious picture. Moreover, the author's imagination is so magical and wonderful that the stars without feelings in the ice Leng Ye sky can still praise each other, and the author expresses his pursuit of "human love" very implicitly. You can see such a short poem and embody such a great spirit. I think grandma Bing Xin must have been very careful when she wrote it. It's nothing. Look at these words again:

Mom! The wind and rain came, and the birds hid in the nest;

The storm in my heart is coming, so I can only hide in your arms. A few words praised the noblest and most selfless maternal love. She enthusiastically praised maternal love. I expressed my heartfelt thanks to my mother. The whole association is natural and gentle to read.

In Spring Water, there is a passage that I can't forget for a long time. "Spring says to the youth from the green grass:' My light is on you, creating your living personality from the cold environment!' The poet tells people with personification that the dawn of revolutionary victory has come, and people should warmly welcome a better life in the future and create their own brilliant life. This is also a portrayal of the poet's revolutionary optimism and enthusiasm.

In a word, I think grandma Bing Xin's poems are shining stars in the vast night sky, small flowers scattered on the forgotten banks of the river, and they always exude refreshing fragrance.

The work "Springs of Stars" inspired me a lot. She told me about human's pursuit of love, the greatness of maternal love, and that I should be optimistic about life ... which touched my great spirit and kindness.

Appreciation of famous sentences: "childhood is the truth in dreams, the dream in reality, and the tearful smile when recalling" in Stars. It is conceivable that Bing Xin's childhood was full of dreams and childish fantasies.

"Little brother, ... a child in the depths of the soul." It also explains the indescribable deep friendship between Bing Xin and his brothers and sisters. These are Bing Xin's childlike longing and happiness.

"mom! You are a lotus leaf, and I am a red lotus. The raindrops in my heart are coming. Except you, who is the shade under my empty sky? "

Experience homesickness: "the waves of my hometown!" The waves you splashed once pounded my rock bit by bit, and now they pounded my heartstrings bit by bit. "

The wrong problem analysis of biogenetics in senior one is urgent! 15。 The ratio of offspring is1:1:1:1,so it must be a test cross type. White-eyed male Drosophila melanogaster can be regarded as recessive homozygous parent: XwY, while red-eyed female Drosophila melanogaster is heterozygote, both of which are XWXw.

2 1。 The separation of B and B, as well as the separation of B and B, is actually the process of sister chromatid separation, in the late stage of negative two. The separation of b and b is actually the separation of homologous chromosomes, which occurs in the late stage of subtraction I.

29。 Let x be the content of the required nucleotide in the mother chain and n be the repeated number, then the required free nucleotide is: X(2 to the nth power-1), and the number generation is: 60(2*2- 1)= 180.

40。 Because three pairs of alleles are on non-homologous chromosomes, they follow the law of free combination. Firstly, AaBbCc is divided into three pairs of alleles: Aa, Bb and Cc. See Aa can produce two kinds of gametes: A, A, Bb and Cc. So the number of gametes produced by AaBbCc is 2*2*2=8. Self-cross progeny: Take aaBbCc apart and see that Aa self-cross can produce three genotypes: Aa, Aa, AA, Bb and Cc self-cross. Then the total number of offspring that AaBbCc can produce is 3*3*3=27.

42。 Because the synthesis of phage protein needs phage DNA to guide the synthesis, but only phage DNA can enter bacteria, so the raw material for the synthesis of protein-amino acids can only come from bacteria.

50。 Because both parents have brown eyes but blue eyes A and C, the genotype of parents must be heterozygote. However, A and C are blue-eyed recessive traits, and the genotype can only be recessive homozygote. B is brown eye, and the genotype can be dominant homozygote or heterozygote.

Seek a key question type in senior one chemistry, which is urgent ~ ~ ~ ~ ~ Thank you! Because of too much acid, the amount of gas produced determines the level of the balance. Because the mass of sodium carbonate is the same as that of sodium bicarbonate, while the molar mass of sodium carbonate is 106g/mol and that of sodium bicarbonate is 84g/mol, the generated sodium bicarbonate produces more CO2. The end where sodium carbonate is put is very heavy.

Minors urgently need Italian visas. . . . . . . . . I believe many students who are going to Italy have heard the word "residence" countless times, but what is residence? How to apply? Caring for growth is here to give you a detailed answer.

The so-called residence (permesso di soggiorno) is essentially similar to a temporary residence permit, and it is a certificate for foreign immigrants to legally live in Italy. In Italy and some neighboring countries, the effect of residence is equivalent to visa. If the visa expires but the residence is valid, the cardholder can still freely enter and leave Schengen countries. There are many kinds of houses in Italy. Here, only the dormitories commonly used by students are introduced.

Within 8 working days after entering the country, students must submit documents to the police station to apply for residence permit. Generally speaking, students need to go to the post office in the city center or the post office with the word "AMICO" at the number pick-up machine to get the residence application form (all the application forms and attachments are packed in an envelope). After completing the application form, you also need to provide:

4 ID card photos (white background)

14.62 euro stamp

Copy of passport (copy each page according to the page number)

Show me the original passport.

Proof of accommodation

Sickness, Disability and Pregnancy Insurance Policy

University admission notice

In addition, it is best to provide your own copy of tax number (Codice Tax) and insurance copy (assicurazione). The tax number is one of the important personal information in Italy, and all economic activities in Italy are inseparable from it (such as opening a bank account and signing a rental contract). Generally, to apply for a tax number, you should go to the district office (Certificato di Attribuzione) and just fill out a form with your passport. Generally speaking, you will get a written copy of your tax number information immediately (copy it and put it in an envelope), and a few days later you will receive a card with the same content as the written information. Generally speaking, insurance can be handled at the post office, and the annual cost is 98 euros. Just put the copied payment slip in the envelope of the residence application. Copies of traveler's checks can also be submitted as proof of funds, but there is no hard and fast rule at present.

Some people here may ask, I want to take a language class in Perugia and study in another city in a few months. How do I apply? If this is the case, please apply for residence in the place where the language school is located, and then go to the original city police station for relocation and residence when changing cities.

After submitting the application materials, the post office staff will issue a receipt in triplicate, and the second receipt will be marked with the words UESR ID and password. What is recorded above is the applicant's residence number and inquiry password. A few working days after submitting the materials, you can check whether the application materials are correct and when to go to the police station on the portal immigrazione.it/eli2migrazione web/pagine/startpage.aspx. Generally speaking, it takes about 8 to 10 months to apply for residence for the first time, and some even longer, so this receipt in triplicate must be kept, which is now equivalent to your official residence permit.

Generally speaking, after submitting the application materials, the applicant must go to the local police station at least twice to obtain a residence card. For the first time, he will go to the police station to confirm that the submitted materials are correct and make an appointment to leave his fingerprints next time. The second time, he will leave his fingerprints and pick up the card. If there are problems with the submitted materials or if you want to transfer them to detention, you have to run a few more times. At this point, the application for residence permit is really completed.

I'm still drunk on the internet for such an urgent matter.

Invite professional design friends to come in and help. I have a friend who is in good contact with you. I suggested that she wear a skirt, and it worked well.

But you said it was inconvenient to wear a skirt to work. If you wear pants, try to choose a vertical bar that looks slender, and don't wear tight-legged pants and tight-legged jeans.

Several eighth-grade math problems are urgent! I need it now! 1.y Because the straight line y=mx-3m+2 divides the quadrilateral ABCD into two parts with equal areas, it must pass through A and C, and this function is a proportional function.

If c (10/0,6) is brought into y=mx-3m+2, 10m-3m+2=6, that is, 7m+2=6 and m=4/7.

2. The intersection of (1,2) is the common * * * solution of two equations.

3.y= 12-2x perimeter minus two waists is the bottom.

The sum of two sides of a triangle is greater than the third side, ∴ x+x > 12-2x, and the solution is x > 3.

When x=3, y=6, so x < 6.

The value range is 3 < x < 6.

4.LZ should be able to draw a function diagram. In the straight line y=x+3, when y=0, the distance from x=-3 to the origin is |-3|=3.

Y=-2x+6 When y=0 and x=3, the distance to the origin is 3.

So the distance between two straight lines on the X axis is 6.

The intersection of two straight lines is (1, 4), so the distance from the apex of the triangle to the X axis is 4, that is, the height is 4, so the area is 6×4× 1/2= 12.
