题目内容

They must be your classmates, ________ they?

[　　]

A．aren't

B．must

C．mustn't

D．are

答案：A
解析：

　　本题主要考查学生对must表示推测意义的掌握。在英语的反意疑问句中，我们经常见到前面是一个肯定句，后面是一个简洁的疑问句；表现形式是前句是肯定形式，后句自然为否定，反之亦然。例如：

　　You are a student, aren't you?

　　你是个学生，是吗？

　　She went to see her mother yesterday, didn't she?

　　她昨天看母亲去了，是吗？

　　但在must表示推测的句子中，这其实就是一个颇为肯定的语气，构成该句的反意疑问句时，不能再套用must进行推测，而应该根据动作发生的时间来推测。例如：

　　They must be hungry, aren't they?

　　他们一定是饿了，是吗？

　　You must have forgotten it, haven't you?

　　你想必将它忘了，是吗？

Every morning, the newspaper chief editor(主编) holds a meeting with the reporters. They discuss the main events(事件) of the day. Reporters are then sent to cover the events.
As soon as the reporters know what to write about, they get down to work. They telephone people and fix a time for a face-to-face interview with them. Sometimes they do telephone interviews. Checking information is very important. They go to the newspaper’s own library to look up any information that they need. This is called “doing one’s homework”.
At the same time, the picture editor decides which photographs will be used for the next day’s paper. All the people who work on a newspaper must be able to work fast. Reporters have to stop working on one story and start working at once on the important new one. They must find out the new information as quickly as possible. Later in the day, everything is put together at the news desk. Reporters return, type their stories into the computer and hand them to the editor.
The chief editor decides which will be the most important story on the front page. Sometimes this will have to be changed if something more important happens late in the day. Other editors read the stories which the reporters have written and make any necessary changes.
Finally, there is no more time left for adding new stories, and the time for printing(印刷) the newspaper has come. This is done on fast-moving printing machines. The newspapers are then delivered(发送) by truck, plane or rail. Speed is important. People want to buy the latest newspaper; nobody wants to buy yesterday’s.

Once upon a time there lived an old man. He had three sons. One day, he called them together and said, "Sons, I will die soon. To my oldest son I give half my camels, to my second, one-third(三分之一), and to my youngest, one-ninth (九分之一)." Soon after that he died.
Now, the old man had seventeen camels, and the three brothers didn’t know how to do as their father said. They thought a long time about the problem, and it seemed that they must either kill some of the camels and cut them into pieces, or disobey their father. At last they went to their father’s old friend and asked for his advice. As soon as he heard their story, he said, "I will help you. I was a good friend of your father’s. I am old. I have only one camel, but take it-it is yours."
The three sons thanked the old man and took his camel. Now they found it was easy to do as their father wished, The oldest took half- that was nine camels; the second took one-third, that was six; and the youngest took one-ninth, that was two.
After each had got his camels, they found that there was still a camel there. So, to show their thanks to their father’s friend, they gave the camel back to him.

Play is the basic business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy（婴儿）, every child needs opportunity and right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.

In recent years, research on baby development has shown that the standard a child is likely to reach, within the range of his inherited（遗传的）abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.

In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws（七巧板）and construction toys; painting, scribbling（涂鸦）and making things; sand and water play; toys for imaginative and pretending play—the first social games for learning to play and get on with others.

But at the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school．It is easier to see which type of toys the child most enjoys.

Until the age of seven or eight, play and work mean much the same to a child．But once reading has been mastered, then books become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.

1. What does the writer want to tell us in the first paragraph?

A. Children should choose toys by themselves.

B. Children like playing, but they don’t need any toys.

C. Children should be given different toys as they grow up.

D. Children should be given the same toys as they grow up.

E. 58．According to the passage, we can give the child every kind of toys ________．

A．when he is two B．when he is around four

C．when he is six D．when he is eight

2.When a child is seven years old, what is the main source of learning?

A. Toys. B. Books. C. Jigsaws. D. Paintings.

3. What is the article mainly about?

A．The importance of schooling.

B．The choice of toys for children.

C．The importance of pre-school education.

D．The role of play in a child’s development.
