阅读理解下面的短文,然后按要求答题。
It was two months before Christmas, when nine-year-old Almie Rose told her father and me that she wanted a new bike. Her Barbi bike was just too old, and it needed repairing as well.
As Christmas came nearer, her dream for a bike seemed to disappear, so we thought, for she didn't mention it again. We were busy buying some beautiful story books, a doll house, a holiday dress and toys. Then much to our surprise, on December 24, she said she really wanted a bike more than anything else.
Now we didn't know what to do. It was just too late. We were busy with Christmas dinner and packing children's presents, parents' presents, a brother's present and friends' presents till midnight. So there was no time to take to buy the &right bike& for our little girl. Thinking that we were parents who would make their child unhappy, we felt guilty and sad.&
Suddenly my husband came up with an idea. &What if I make a little bike out of clay (泥土) and write a note that she could trade in (交换) the model bike for a real one?& So he spent the next five hours carefully working with clay to make a small bike.
On Christmas morning, we were so excited for Almie Rose to open the little box with the beautiful red and white clay bike and the note. She opened and read the note loudly. She looked at me and Ron and said, &So, does this mean I can trade in this bike for a real one?& Smiling, I said, &Yes.& Almie Rose had tears in her eyes when she replied, &I would never trade in this beautiful bike that Daddy made me. I prefer to keep it rather than get a real bike.& At that moment, we would have moved the God to buy her every bike on the earth.
( )⒈ Rose's wish was to ___ on Christmas Day.
A. get a new bike   B. make a clay bike
C. receive a doll house D. repair her old Barbi bike
( )⒉ Rose's parents didn't buy her a bike because she ___.

( )⒋ Rose's father got a good idea to ___.
A. spend five hours working with clay
B. make a small bike out of clay
C. make her old bike red and white
D. put the present in a box
( )⒌ From Rose's words in the last paragraph, we know that she ___.

根据短文内容, 指出能完成所给句子的最佳答案。
New rules and behaviour standards (行为规范) for middle school students came out in March. Middle school is going to use a new way to decide who the top students are. The best students won't only have high marks. They will also be kids who don't dye (染) their hair, smoke or drink. The following are some of the new rules.&
Tell the truth. Have you ever copied someone else's work on an exam? Don't do it again! That's not something an honest student should do. If you have played computer games for two hours in your room, don't tell your parents you have done homework.
Do more at school. Good students love animals and care for other people. April is Bird-Loving Month in our country. Is your school doing anything to celebrate? You should join! That way, you can learn more about animals and how to protect them. When more people work together, it makes it more fun for everyone. Have you ever quarreled with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, not only yourself.
Be open to new ideas. Have you ever thought that people could live on the moon? Perhaps you'll discover Earth II someday. Don't look down on new ideas. Everyone's ideas are important. You should welcome them, because new ideas make life better for everyone.
Protect yourself. Has someone ever taken money from one of your classmates? Don't let it happen to you. If you have to go home late, you should let your parents know.
Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet aren't for kids, so try to look at Web pages that are good for you. You can use the Web for fun or homework. Can't you find any good Web sites for children? Here are some:
http ://kids. eastday. com
http ://www. chinakids. net. com
http: //www. cycnet. com

Once Einstein gave a lecture in many places in America. His driver always listened to him and knew the lecture so well that he was sure that he could give it himself. So Einstein agreed that the driver would give the lecture instead of him the next time.
As nobody knew Einstein there, the driver gave the lecture for Einstein that evening. At first he was a bit afraid, but Einstein's smile made him feel better. He gave such a good lecture that the people were quite pleased with him. Then the driver started to leave and Einstein followed him without a word. When they got to the door, a man asked the driver a difficult question. The driver said that the question was very easy, and told the man to ask his driver who followed him behind to answer it instead of him.

One possible version:
The environment is becoming worse and worse. There are many kinds of pollution I worry about. The most serious two are water pollution and air pollution, because people can't live healthily with dirty water and polluted air, nor can animals. More and more diseases are caused by polluted air.
I think factories should not pour dirty water into the river directly or produce more waste gas. We'd better go on foot or by like instead of by car, because more cars mean more waste gas. We should make our world more and more beautiful.
Another possible version:
The first fact I worry about is noise pollution. People can't sleep well if there is too much noise. That's why so many people prefer to live in the countryside rather than live in the noisy city. I suggest all the factories and cars shouldn't make terrible noises. If they make terrible noise that isn't allowed, they will be fined, and we can also produce the cars which can't make terrible noise.
The other pollution is rubbish pollution. If everyone makes so much rubbish, one day we may live in a world filled with rubbish. Some people throw the waste paper about. I suggest rubbish should be put into different kinds of dustbins or paper bags.
评分标准:
1. 内容完整,语句流畅,无语法错误,书写规范,给9-10分;
2. 内容较完整,语句较流畅,基本无语法错误,书写较规范,给6-8分;
3. 内容不完整,语句欠流畅,语法错误较多,书写较规范,给3-5分;

Dear Miss Zhao.
As you know, I've made a great progress in English with your help. At this moment, I want to say &Thank you&.
I still remember when I began to learn English. I found it too difficult. No matter how hard I tried. I still couldn't do well in it. I lost my confidence and almost gave it up. As soon as you knew it, you had a long talk with me kindly about how to learn English well. You always encouraged me whenever I made a little progress. Ever since then I have been interested in it and improved myself a lot.
Though I have to say goodbye to you very soon, I still think I am so lucky to be your student. I hope you can relax yourself and keep healthy. Best wishes to you!
