As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind.

Let’s think about how this works. As wave energy passes through the water, the energy makes particles （粒子） of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn’t move forward. That’s because the wave energy just moves the water which is under the basketball.

　  So why can you see a wave knock you down on the shore？When a wave moves toward the shore, the bottom of the wave slows down because it meets the ocean floor. But the top, which is called crest(浪峰), keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action.

1.______ is really moving forward when you look at the wave.

A．Water            B．The basketball      C．Water and wave energy   D．Wave energy

2.Match the sentences with the pictures and the right answer.

(1) The basketball moves up to the top with the wave.

(2) The basketball continues and leaves the basketball behind.

(3) When the wind blows, a wave comes from behind the basketball.

A．a—(2) b—(1) c—(3)                     B．a—(3) b—(1) c—(2)

C．a—(1) b—(3) c—(2)                     D．a—(3) b—(2) c—(1)

3.Which of the following is NOT true according to the passage?

A．Wave energy comes from the water.

B．Large waves carry plenty of energy.

C．Wave action makes shorelines change all the time.

D．The bottom of the wave is easy to slow down.

4.The underlined word “it” ( Paragraph 3) refers to “________”.

A．particles of water   B．the shore          C．the wind          D．the bottom of the wave

5.The main idea of this passage is ______.

A．what makes particles of water move         B．how a basketball moves on the ocean

C．how wave energy causes wave action        D．why a wave can knock you down

We each have a memory(记忆力). That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
　　A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one can , because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the students have so little time for it, and they are busy with other subjects , too. But your memory will become better and better when you do more and more exercises.

Exam time is the most stressful (最有压力的) period of the year. You've worked all the term on your classes and now it's the time to prove what you have learned. With so much at stake, it is easy to get stressed about your exams. However, with the right amount or hard work and focus you can pass your tests    1!

When I was in school, I used to get very stressed over my examinations. So did my friends. Some people stopped eating and others ate too much! Some     2 and others burned themselves out! The most important thing to remember when studying is not to panic! Take the middle path---stay calm, eat healthy food and get your rest. Stressing out and _3___yourself too hard is just as dangerous as not studying enough. A tired, overworked brain is just as useless as a stupid, empty one!

So, what do you do? Set aside a time each day for study and a time For __4 . You may have less time to relax than usual, but you still need to let your brain rest for a few moments. Get plenty of sleep. If you are_ 5  , information will not stick in your memory. Finally, eat healthy food that fuels your body and mind.

It does no good to look at your exams like the rest of your life   6  them. Instead, just view them as another obstacle (障碍物) you will overcome. You have overcome all kinds of obstacles in your life so far. With the right amount of work and focus, you will pass your examinations with flying colors! High school is right around the corner.

I have 　35 friends, and we always play football together at school or in the park after school. We like staying out late to play football. We often play for three hours or more and forget when to stop. Then I 　36　 trouble at home because my parents do not allow me to play outside after 6 p.m. I really do not understand why they are so strict. I feel stressed and angry　　 37　 . I believe it is important for us to spend some time on our hobbies. They can help us relax and make our lives 　 38　 .I wish I could have my parents’ 　39　 .

Is it bad to stay out late to play football? Should I spend less time on it? I really do not know　 40　 . Can you please advise me how to achieve a balance between my schoolwork and my hobbies? Thanks a lot.
