　　Even if you are a good high-jumper, you can jump only about seven feet off the ground. You cannot jump any higher because the earth pulls you hard. The pull of the earth is called gravity.

　　You can easily find out the pull of the earth. If you weigh (稱體重) yourself, you will know how much gravity is pulling you.

　　Since there is gravity, water runs downhill. When you throw a ball into the air, it falls back down. Because of gravity you don't fall off the earth as it whirls (旋轉(zhuǎn)) around.

　　Then, can we get away from the earth and go far out into space? Now you can do it, because spaceships have been invented. The spaceship will go so fast that it can escape (逃離)the earth's gravity and carry you into space.

(1) In this passage (文章), the word “gravity” means

[　　]

A. the pull of everything

B. the force (力) which attracts (吸引) the earth towards us

C. the force of attraction among things

D. the force which attracts things towards the center of the earth

(2) When you slip (滑倒)on something, you

[　　]

A. always fall down to the ground

B. sometimes fall down to the ground

C. go up into the air

D. often fall off the earth

(3) Gravity is so strong that ________

[　　]

A. it can't make you throw a ball into the air

B. it can keep everything on the earth

C. you can jump at least seven feet high

D. you can't go up into the air by spaceship

(4) Because of “gravity ”,________

[　　]

A. water flows (流) everywhere

B. we can go everywhere by ship

C. water flows downwards on the earth

D. water flows at the foot of hills

(5) We can get away from the earth by spaceship because

[　　]

A. the spaceship goes very fast

B. the earth has no gravity to the spaceship

C. the spaceship has a strange energy (能量)

D. the spaceship can go higher than any other thing on the earth

　　The world is not only hungry，but it is also thirsty for water．This may seem strange to you，since nearly 70 % of the earth's surface is covered with water．But about 97 % of that is sea water，or salt water．Man can only drink and use the other 3 % ——the fresh(清新的)water from rivers，lakes，underground，and other sources．And we can not even use all of that．Even worse，some of it has been made dirty．

　　However，as things stand today，this fresh water is still enough for us．But our need for water is becoming larger and larger quickly-almost day by day．Only if we take steps to do with this problem now can we get away from a serious world-wide water shortage later on．

　　We all have to learn how to stop wasting our valuable water．One of the first steps is to develop ways of refusing it．Today in most large cities，water is used only once and then sent out into a sewer system(下水道系統(tǒng))．From there it returns to the sea or runs into underground places．

　　But even if every large city reused its water，we still would not have enough．All we'd have to do to make use of sea water in the world is to remove(清除)the salt．If we take these steps we'11 be in no danger of drying up．

(1)

(b)carry salt water into lakes or rivers

(d)try to save the fresh water as much as possible
