Dear students,
Time goes by, we have spent a really good school year, and now come to the end of the term. I believe all of you are excited about the winter holiday, aren't you ?
In order to enjoy a funny and meaningful holiday, it is necessary for us to keep learning after you spend time with your relatives or your friends.
Here are six tasks for you during the winter holiday,
. Next term, we'd like to choose some best students
who can do the homework well.
At last, wish you a happy new year,and see you next term.
Best wishes, Miss Xiang

第二节 阅读理解
阅读下面短文,从短文后所给各题的四个项中,选择最佳

Here are some suggestions which may help you to master the Enlgish language.
The biggest problem most people face in learning a new language is their own fear. They worry that they won’t say things correctly or that they will look stupid so they don’t talk at all. Don’t do this. The fastest way to learn anything is to do it — again and again until you get it right. Like anything, learning English needs practice. Don’t let a little fear stop you from getting what you want.
Listening to English music can be a very effective(有效的)method of learning English. In fact, it is often used as a way of improving understanding. The best way to learn is to get the words to the songs you are listening to and try to read them as the artist sings. This way you can practice your listening and reading at the same time.
Many people think that exercises and tests aren’t much fun. However, by completing exercises and taking tests you can really improve your English. One of the best reasons for doing lots of exercises and tests is that they give you a benchmark(基准)to compare your future results with. Often, it is by comparing your score on a test you took yesterday with one you took a month or six months ago that you realize just how much you have learned. If you never test yourself, you will never know how much you are progressing. Keep doing this and you really will make some progress with English.
67. The biggest problem most people face in learning a new language is ______.
A.their own fear B.their ways of learning
C.their time D.their mother tongues
68.Which of the following is often used as a way of improving understanding?
A.Watching TV. B.Reading English stories.
C.Listening to English music. D.Watching English films.
69.What’s the main idea of this passage?
A.The importance of learning English.
B.Some suggestions about how to master the English language.
C.The use of English.
D.Some problems in learning English.

The compass(指南针)is one of the Four Great inventions of Ancient China.
Before the compass was invented, people depended on the position of the sun
and stars to tell them the direction when at sea, which only worked when it
wasn’t cloudy. As early as the Warring States Period. Chinese people discovered
that a magnet could show the south and the north, and, on the basis of this
feature, they made a southward-pointing instrument that was the model of the compass. The instrument was made up of a smooth magnetic spoon and a copper(铜)plate carved with directions;the handle of the spoon pointed south. In the Song dynasty, people combied an artificially(人造地)magnetized compass with an azimuth(方

With the development of society, cars are becoming more and more popular in China. However, some people have realized the serious problem of air pollution caused by cars. It is necessary to find ways to solve the problem.
One way is to produce a new kind of pollution-free car. That’s what weveral large car factories are trying to do. But to produce a pollution-free car is easier said than done. Progress in
this field is slow. Another way is to take the place of the car engine(发动机)with something else. Many makers believe that it will take years to develop a practical(实用的)model that can please man.
To prevent the world being polluted by cars, we have to make some changes in our life. We have to cut down the number of our cars and encourage traveling and going to work by bike or on foot.
We may live a happy and sad life a long time because of the car problem.

there.
M: When are you leaving?
W: I’m leaving at 9 a.m. on Friday, July27.
M: Will you get there by plane?
W: Of course.

W: I know you like music, but you’ve turned up the radio too loud. I’m sorry to have to say this,
but I can’t stand such loud noise.
M: I’m sorry, Mum. I didn’t know I was troubling you.
W: You see, it’s quite difficult to fall asleep with such loud music every night. It leaves me
tired out during the day.
M: Well, I’ll turn it down right now.
W: Thanks. I do hate complain, but it has made me tired these days.
M: I’m really sorry. I won’t do that again.

W: Dad, the weatherman says it will be fine tomorrow. I don’t want to stay at home.
M: Should we go to the park for a boating?
W: Again boating? I am tired of it.
M: So we can have a ride in our new car to the country. The air is fresh there.
W: That sounds good! We haven’t gone to the country for a long time.
M: Why don’t you ask your mother if she want to go with us?
W: I think she should stay at home and make dinner ready before we come back.
M: That’s an idea. But there is a problem.
W: What is it? M: Your mother told me she is also interested in the car ride, too. If all three of us go out, who
will prepare for dinner?
W: Why don’t we eat out in a country restaurant? Then we can go together.
M: OK. It’s decided.

Long time ago, there was a poor man. He had an orange tree. He took good care of it. In autumn there were many fine oranges on the tree. One of them was very, very big. It was as big as a football. Nobody saw so big an orange. The king was so pleased that he gave the poor man a lot of money for it. When a rich man heard of it, he said to himself, “It’s only an orange, why did the king give the poor man so much money? I’ll take my gold cup to the king. He’ll give me more money.
The next day when the king received the gold cup, he said to rich man, “What a beautiful cup! I’ll show you something wonderful. Please take this great orange away.”
