I'm captain of our school team so with my

1．________

fellow players we've won several games. There

2．________

will an important game next month. But one of the

3．________

best players in our team told me just then that he

4．________

wouldn't play basketball once more. His parents

5．________

asked him to spend in more time preparing for the

6．________

College Entrance Examination. I feel sorry to him.

7．________

But his parents think go to college is more important

8．________

than playing sports and college was the only place

9．________

for a smart boy like his son. So my friend had no

10．________

Choice. He wanted to make his parents happy.

Nobody can tell exactly why people first began to use salt,

1．________

but it is well-known that salt has used in many different ways

2．________

throughout history. People who lived over 3 000 years ago ate salted

3．________

fish. In ancient Egypt, salt was used to preserve dying bodies.

4．________

Stealing salt were regarded as a serious crime in different

5．________

times. In the 18th century, for example, a person was

6．________

caught stealing salt, he was put into the prison. In the

7．________

Roman Empire, one of the most important road was built

8．________

specially for salt to be carried from the mines to Rome.

Guards were sent to protect the salt from stolen.

9．________

The guards got their pay in salt, from which the

English word “salary” originated. Any guard fell asleep

10．________

while on duty was said to be “not worth his salt”. This

is still used today in English.

I used to love science class－all of them－

1．________

biology, chemistry, geography, and physics. I think I

2．________

liked those classes because I felt that it helped me

3．________

understand what the world works. For example, when

4．________

I was a child, the rain was a mystery (奥秘). In one

5．________

class, I learned it rained. I think science classes

6．________

clear up mysteries. But then there is always more

7．________

mysteries look into. What was my least favorite class?

8．________

That was maths. After learn the basics of the subject,

9．________

nothing else seemed very practically to me. I never

10．________

saw how I could use it in my daily life.

Waves are beautiful to look but they can destroy

1．________

ships at sea, as well as houses and buildings near

2．________

the shore. Which causes waves? Most waves are caused

3．________

by winds blowing over the surface of the water. The

sun heats the earth, causing the air to rise and the

winds to blow. The winds blow cross the sea, pushing

4．________

a little waves into bigger and bigger ones. The size

5．________

of a wave depends on how strong the wind is, how long

it blows, and how heavy the body of water is. In

6．________

a small bay (海湾) big waves will never build up.

So at sea the wind can build up powerful waves.

7．________

A rule says that the height of a wave (in

meters) will usually be no more than one-tenths of

8．________

the wind's speed (in kilometres). In another words,

9．________

when the wind is blowing 120 kilometres per hour, most

10．________

waves will be about twelve metres.
