How can we know that the birds we see in the South in the winter are the same ones that come north in the spring? Once John J. Audubon, a bird 　1 (love), wondered about this. Every year he 　2 (watch) a pair of little phoebes nesting in the same place. He decided to put tiny silver bands(箍) on　 3　 legs. The next spring, the birds 　4 the bands came back in the very same place. The phoebe, it was learned, spent winter　 5 it was warm enough to find food. Today there are hundreds of birdbanders all over America.

The government of the U.S. has a special birdbanding department　 6 makes all the birdbands. The bands do not hurt the birds, as they are made 　7　 aluminium and are very light. Each band has 　8 special number. On each band are these words: “Inform Fish and Wildlife Service, Washington, D.C”.

Anyone who finds a dead bird with a band on its legs 　9 (ask) to send the band to Washington with a note 　10 (tell) where the bird was found. In this way naturalists add to their knowledge of the habits and needs of birds.

Perhaps I am Courageous, but that's because I've had some inspiring teachers. I'll tell you about one of them. Many years ago, when I worked　 1 a volunteer at Stanford Hospital, I got to know a little girl named Liza 2 was suffering from a rare and serious disease, Her only chance of 　 3　 (recover) appeared to be a blood transfusion (输血) from 　 4　 five-year-old brother, who 　 5 (survive) the same disease and developed the antibodies needed to combat the illness. The doctor explained the situation to her little brother, and asked the boy 　6 he would be willing to give his blood to his sister. I saw him hesitate for a moment　 7　 taking a deep breath and saying, "Yes, I'll do it if it will save Liza."

　　 As the transfusion progressed, he lay in a bed next to his sister, 8 (smile). But then his face grew pale and his smile faded. He looked at the doctor and asked with 9 trembling voice, "Will I start to die fight away?"

　　 Being young, the boy had misunderstood the doctor. He thought he was going to have to give her 10 his blood.

Recently I failed an exam．However, 　1 I came out of my teacher's office．I told myself: "Smile! It's not so serious. "

I smiled a big smile and　 2　 worked a little, really．Everyone gets 　3　 （frustrate） sometimes．I used to be always influenced by pressure and I was often in low spirits．But one day I came 4 a sentence in the Bible: “Do not be anxious about tomorrow, for tomorrow will he anxious for itself．Let the day's own trouble be sufficient for the day．" It suddenly struck me: " 5 （worry） about a problem doesn't help．Why not just give a big smile and face up 6 the trouble?"

Now every time I want to cry, I remind myself that 　7　 （laugh） is better than tears and anger．I 　8 （convince） that there's something magical about a smile．A smile helps me recover confidence and gives me 9 courage to move on．

Remember, whenever you're faced with a setback, whenever you've been treated unfairly, all it takes is determination and you can feel happy again．Smile at life． 10 it will shine on you．

Christmas Eve means a warm get-together with friends, a candlelight dinner, or perhaps a celebration at a pub for students. But, for Cai Yingjie, 　 1　 unusual night has a different meaning: helping beggars and the homeless.

Cai, a student in journalism at Tsinghua, could be found at Beijing’s Wudaokou Light Railway Station that special evening. 　2　 she saw an old beggar, she took the cold, rough hands of the woman with her warm, clean hands, 　3 (give) the woman some warm bread and helped her put on a pair of new gloves.

The woman was surprised for a few seconds, then burst into tears, saying “ 4 the first time I feel respected”.

Cai said, “A beggar’s life is even 5　 　(hard) today. That’s why I want to help them.”

They brought bread and gloves with them, and stopped to greet beggars and offer 　 6　 some of the warm food. Each beggar greeted them 7 a look of surprise.

“I know the 　 8 (active) can’t help much, but it is meant 　 9　 (show) our respect and care for beggars and the homeless 　 10　 have been neglected for so long,” said Sun, head of the group.

In every school a “top” crowd sets the pace，while the others follow their lead. Let’s say the top crowd decides that it is smart to wear bright red sweaters. Pretty soon everybody is wearing   1 bright red sweater. There is nothing wrong with that,  2    the fact that on some people a bright red sweater is   3    (extreme) unbecoming(不得体的). The situation can even become dangerous，if the top crowd decides that it is smart to drink or to drive cars at seventy miles an hour. Then the people    4   (follow) the lead are endangering their lives. They are like the sheep’s   5   (lead) to the butcher. Now, chances are    6    you have come across situations like these more than once in life; your chances are that one time or    7    you probably did something you knew to be wrong. You may have excused yourself by saying，“Gee，the crowd does it. ”Well，let the crowd do it，but don’t do it yourself. Learn to say，“No.”

Develop your own standards and your own judgment.    8    you know the crowd is planning something you   9     (agree) with，have the courage to bow out(辞职) politely. You’ll have the   10    (satisfy) of standing on your own two feet.

Reporting the news through photos is called photojournalism. At times photojournalists tell their stories 1 a single picture . At 2 times, they use a group of pictures to tell a story. Each picture is like a chapter in a book, which can do more than record the facts. It can also be a strong force for social change .

Jacob Riis was among the first photojournalists .He took pictures of parts of New York City 3 the poor lived. Riis believed that 　4 (poor)caused crime, and his point 5 (prove)by his photos. A few years later, the photos of small children 6 (work)in factories by Lewis Hine shocked 7 public. Hine’s pictures helped bring 8 laws to protect such children.

　 Hundreds of pictures may have to be taken in order to get one or two really good photos.It takes science to have the photo come out clearly and art to make a photo that has a good design and expresses feeling. Photojournalists make an actual record of 9 they see. A photo, 10 ,can be both a work of art and an actual record . It can record an important event as a beautiful or exciting picture.

　 As historical and artistic documents(文献)，photos can become more important over time.
