根据短文内容完成下列句子。

     As an American,I was surprised to learn that Chinese students must be good at sports in order to get

a top grade in PE class.  In the US, all you have to do to get an A in PE class is show up in proper gym

clothes and look like you're trying.

     This is lucky for kids like me who aren't great at sports.  At my school, we had PE class twice a

week. Every few weeks, we changed the activity we were doing. For a few weeks we played football.

That was okay I was good at it.  But then we switched (转换) to baseball, and I was hopeless. I couldn't

hit the ball at all!

     Luckily, under the American system, trying my best was enough. When I missed the ball, I knew it

didn't matter. I'd still get a good grade.

     During the school year, we played many different sports, including American football, badminton,

gymnastics (体操), tennis, golf, swimming and rock-climbing.  Every few months, we spent a few weeks

in health class. Instead of going outside or to the gym, we sat in a classroom and learned about the

human body and first aid (急救).

     At PE classes, we learned a little, exercised a little, and had lots of fun.

1. The Chinese students must be good at sports in order to _______.

2. The writer is an American and is not _______ sports.

3. If you are  a  student in an American school, you are not good at sports but you still _______ .

4. During the American school year, the students have many different PE classes like _______.

5. The students in America can learn a little, _     ___ a little and had lots of fun at PE classes.

阅读理解。

     This year in your grade you will have a lot of reading to do. You can do more of it in less time if you learn

to read rapidly.

     Perhaps you have been told about some habits which keep a person from reading fast and have been strongly

asked to break those habits which you might have.

     Do you still have any of these bad habits? Check yourself by answering "yes" or "no" to these questions:

     a. Do you move your lips when reading silently?

     b. Do you point to those words with your fingers as you read?

     c. Do you move your head from side to side as you read?

     d. Do you read one word at a time?

     If you answer "yes" to any of these questions, start at once to break the habit. If you move your lips, hold

your fingers over them, or hold a piece of paper between your lips while you are reading. Then if your lips

move, you will know it and stop them moving.

     If you point to words, hold the two sides of your book, one side with your left hand, the other side with your

right hand. Then you won't have a free finger to use in pointing while reading. If you move your head, place

your chin in one hand, and hold your head still.

     If you read no more than one or two or three words at a time, you need to work very hard in learning to take

in more words at each glance when your eyes are traveling across the lines of words.

     Even if you do read fairly fast now, you can learn to read even faster. As you probably have been told, the

secret of fast reading is to take in whole groups of words at each glance. Read in groups and force your eyes

along the lines of words as fast as you can make them go. Anyone who practices doing these two things will

be able to read faster.

1. While reading, you should _____.

A. not hold your books with your hands

B. not keep your head still

C. not use your finger to point to the words

D. do all of the things mentioned in A, B and C

2. You may hold your fingers over your lips when you read so as _____.

A. to feel whether your lips move or not

B. to tell others to be silent

C. to keep yourself from talking to others

D. to hold a piece of paper between them

3. When your eyes travel across the lines of words, _____.

A. you need to read the words out

B. you need look at every word carefully

C. you need to remember every word

D. you need to read several words at a time

4. If you can read fairly fast now, _____.

A. you don't need to learn to read faster

B. you can learn to read even faster

C. you can go on reading like that

D. you can enjoy reading
