It was a dark and cold night. The car driver didn’t have even one passenger all day. When he went by the railway station, he saw a young man coming out with two bags in his hands. So he quickly opened the door of the car and asked, “Where do you want to go, sir?”

“To the Star Hotel,” the young man answered. When the car driver heard that, he didn’t feel happy. The young man would give him only three dollars because the hotel was not far from the railway station. But suddenly, he had an idea. He took the passenger through many streets of the big city.

After a long time, the car finally arrived at the hotel. “You should pay me fifteen dollars,” the car driver said to the young man. “What! Fifteen dollars? Do you think I’m a fool?

Once upon a time there was a wise man that used to go to the sea to do his writing. He had a habit of walking on the beach before he began his work. One day he was walking along the shore. As he looked down at the beach, he saw a human figure moving like a dancer. He smiled to himself at the thought that someone would dance on the beach. So he began to walk faster to catch up. As he got closer, he saw that it was a young man and the young man wasn’t dancing, but instead he was reaching down to the shore, picking up something and throwing it into the ocean. As he got closer, he called out, “Good morning! What are you doing?’’

The young man paused, looked up and replied, “Throwing starfishes (海星) in the ocean.”

“I guess I should have asked, why are you throwing star fishes in the ocean?”

“The sun is up and the tide is going out.And if I don’t throw them in, they’ll die”

“But, young man, don’t you realize that there are miles and miles o f beach and starfishes all along it. You can’t possibly make a difference!”

The young man listened politely. Then he bent down, picked another starfish and threw it into the sea, and said, “It made a difference for that one.” The wise man nodded and smiled.

As a matter of fact, there is something very special in each and every one of us. We have all been gifted with

the ability to make a difference. And if we can know that gift, we will gain through the strength of our vision of the power to shape the future.

We must each find our starfish. And if we throw our starfish wisely and well, the world will be better.

“I don’t like my parents. They always tell me I should do this, and should not do that. It sometimes makes me angry,” said Li Ping, a middle school student in Hunan. Do you have the same problem? Perhaps your parents had the same problem when they were your age long ago. Why does it seem that some parents are not so friendly in their children’s eyes?

One of the biggest things is when someone becomes a parent, he/she likes worrying things. They worry about everything about you, from the time you were born. They do a lot for you, though something would make you angry, because they care about you and worry about you. They worry about your choice of friends, the food you eat, your work at school, how much sleep you get, etc. All these things are part of your life. They want you to grow up healthily and happily.

So how can you make things easier on yourself? It’s easier than you think. Just make sure your parents know what you’re doing. Get them to know your friends. Phone if you stay somewhere else so that your parents don’t call every hospital in the phone book looking for your body. Say sorry to them when you make mistakes. Take responsibility for what you have done. Talk about your ideas with them. They may talk about theirs with you.

Most of all, try to think about why your parents do this or do that. They are still practicing being parents and need help you can give them. Someday, when you become a parent, they may be able to help you know how to get on with your children.

63. What does the writer think we should do if we go back home later than usual? We should_____

A. tell our friends

B. say sorry to our parents

C. tell the teacher

D. make a telephone call to our parent

64. The writer thinks________

A.it’s wrong of parents to worry about their children too much

B.some parents are unfriendly, which makes their children angry

C.children should do everything as their parent say

D.parents love their children very much and the children should understand them

65. Which do you think is the best title for the passage?

A. Parents’ Responsibility

B. How to Get on with Parents

C. Zhang Hua’s Problem

D. What Are Parents Worrying about

五、任务型阅读(10’)

Nine-year-old Barrack Obama was looking through a magazine. But the African-American boy was shocked by some photos. The pictures were of a black man who destroyed his skin with chemicals that promised to make him white. For the first time, the boy began to doubt who he was. “I stood in front of the mirror and wondered if something was wrong with me,” Obama said.

However , now , the boy who used to struggle with his identity（身份）doesn’t see it as a problem any more , but an advantage for his success. Obama has made history by being elected as the first black president of the United States.

Obama’s story starts in another corner of the world. His white mother was born in the heartland of the US. His black father grew up in a village in Kenya. They met during college in Hawaii, but his father left the family when Obama was just two years old and his mother moved to Indonesia.

At 10, Obama moved back to live with his white grandparents in Hawaii. At his class, a white boy asked Obama if his father ate people. Out of embarrassment, Obama lied to his classmates that his father was a prince. “I

kept asking who I am and I ended up trying drug s and drinking ,” Obama remembered.

Things came to change after the young man made friends with those who had a similar background at college. Their experiences back in Africa helped Obama to finally face up to his African identity . He worked hard to become a star at Harvard Law School and the third black senator(参议员) in US history.

At first, few people supported Obama. Many people doubted his unusual background, which left him neither “black” enough nor “white” enough.

But Obama’s pains of growing up made Americans believe: “There is not a black America and a white America--- There is the United States of America.”
