When I was in high school, most of my friend had bicycles．I hope I could also have it．One day I saw a second-hand bicycle, that was only one hundred yuan．I asked my father the money．But he said he could only give me half the money．He should find the other half myself．So I went to sell newspapers after the school．My father was pleased if I showed him the money a month after．He gives me the other fifty．You can imagine how much happy I was when I rode to school on my own bicycle.

After the earthquake hit northeast Japan on March 11, 2011, many touching stories that I saw with my own eyes happened around me.
I had to walk home since all the  31 had stopped after the quake. On my way home I  32 an old Japanese lady at the bakery shop who was giving out free bread, which made my heart  33 . A middle-aged Japanese man was holding a sign that said, “Please use my  34 .” He was  35 his house for people to go to the restroom.
My friend wanted to  36 others. He stood in the cold with a sign “If you are okay with a motorcycle, I will  37 you to your home.” And then I saw him take one gentleman home, all the way to a faraway place!
Then the next day I drove to  38 my car with gas. There was a  39 of gas now and many gasoline stations were either closed or had very  40 lines. I got  41 since I was behind 15 cars. Finally, when it was my  42 , the man smiled and said, “  43 the situation, we are only giving $30 worth gas per person. Is that alright?” “Of course, I’m glad that we are all able to  44 ,” I said. His smile gave me so much 45 .
I saw a man at the evacuation (疏散) centre 46 when people brought food to him. It was the first time in three days that food had been brought to their center. However, after he wiped the tears, his next  47 surprised me, “ I am very  48 that we are provided with food. But people in the city next to us haven’t  49 any food at all. Please go to that center as well.” And when hearing that, I realized there is a bright future on the other side of the 50 .

That day I was later for school, so Mom offered me a   36 . I sat beside her in our car, daydreaming about my  37 . I’d be graduating from high school in a few months. I’d leave high school behind and do whatever I wanted. What  38 I do? Go to college? Or get a job in an office where I could  39 my way up?

Mom interrupted my thoughts.“Kassandra, do you  40  that?’’She asked just as we were  41  the railroad tracks. She stopped the car on the other side and   42  the window. “It looks like a child.’’  43 ,I saw a small boy walking by himeself. The warning lights on the train tracks flashed  44 .The boy stayed where he was right in the middle of the   45 .The whistle sounded. There’s no  46  that train can stop in time!The boy jumped up and down and   47  at the engineer.

I took off running. My shoes flopped(松动) against my feet as I   48 , so I kicked them off. I ran faster. Stones crunched(发出刺耳的碎裂声) and flew under my   49  feet. The ground shook. God, let me get to him! The train was almost on top of him. I   50 the boy in my arms. Keep running! But something   51  

me. I fell backward, away from the train. I pulled the boy with me onto safe ground. The train barreled(高速行驶)past. The noise was  52 . The wheels were so close that I could have reached out and touched one.

Once the train was out of  53 , I stood up. Mom ran up and hugged me. “Kassandra, I didn’t think you were going to  54 it !’’

I got ready for bed that night  55 looking forward to school the next day. I wanted to enjoy every moment in life.

Christmas bird – watching is popular in the U.S.A. When the holiday season comes, some Americans are likely to watch and count birds in the sky with great interest every day. This activity began in the early part of the last century. It has a one-hundred-year history. At that time, there was a so-called “holiday hunting” custom. In order to celebrate the holiday, the hunters went out to kill birds and beasts. By 1900, there were 27 bird lovers who decided to count birds instead of killing birds. Since then, Christmas bird-watching was held every year. It has been continued to the present.

There were 42000 people who took part in the bird-watching last Christmas, from December 16 the year before to January 3 next year. They were in the United States and Canada, central America, south America and the Caribbean, watching and counting birds in the sky. The whole viewing area was divided into 1600 points. Each birdwatcher was responsible for 25 meters, and was required to write down the types and quantities of birds within 24 hours.

A birdwatcher described what he had watched vividly in his diary—“ When I looked up, I saw a beautiful ‘landscape’ in the sky: Red-crowned cranes(丹顶鹤) were driving up in cunning wedges that split the air. They were so neatly arranged, coordinating their movements. I was excited and breathtaking. Interestingly, the “human” shape(人字行) always maintains 110° ” .

“Why do red-crowned cranes choose to use ‘human’ shape when flying in formation?” He continued, “In my opinion, there are four reasons: first, the ‘human’ shape can make red-crowned cranes use increasing air which is produced by each other’s wings when they are swinging in the sky. It can increase the glide time and save physical ability. Second, the ‘human’ shape will enhance communication among the birds. The orders and the relevant information issued by the lead bird can be conveyed to each member in this migratory group unimpeded, accurately, rapidly and conveniently. Third, such a formation will help to find the birds left behind because of feeling run down as fast as possible, so that the young, the weak, the sick birds can get everyone’s help and encouragement. Finally, the ‘human’ shape shows not only beauty but also unity. It can give enemies a deterrent.They will be terrified and did not dare to attack the birds.The migration security of the birds will be ensured.”  

Environmental experts admired and evaluated Christmas bird-watching highly. They pointed out that it made perfect sense. On the one hand it could enhance the human awareness of environmental protection. On the other hand it could provide first-hand information on birds.

IF and WHEN often had lunch together. Their conversation always  36  on the things they hoped to achieve and they loved to talk about them.  ]

This particular Saturday when they met for lunch, WHEN  37  IF wasn’t in a great mood（心情）. After they sat at the usual table  38  for them, WHEN asked IF, “You don’t seem your usual  39  self(样子)?” IF replied,“Yesterday I saw a course I wanted to take. If only I  40  the time.”
