四、阅读理解
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 water from rivers,lakes,underground,and other
sources.And we can not even use all of that,because some of it is in the form
of icebergs and glaciers ()Even worse,some of it has been polluted.
However,as things stand today,this small amount of fresh water is still
enough for us.But our need for water is becoming larger and larger quickly
almost day by day.We should take steps to deal with this problem now and in
this way we can 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 reusing it.Today in most large cities,water is
used only once and then sent out into a sewer system(下水道系统).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 the salt.
If we take these steps we'll be in no danger of drying up.
1.The world is thirsty for water because
A.man hasn't got enough food to eat
B.we haven't got enough fresh water
C.only 70%of the earth's surface is water
D.more water is sent into sewer systems
2.The underlined word "valuable"means
A.much and salty B.fresh and enough
C.dear and useful D.clean and helpful
3.What should we do if we want to have enough fresh water?
a.Make full use of the sea water.
b.Carry salt water into lakes or rivers.
c.Try to save the fresh water as much as possible.
d.Do our best to use the water again.
e.Drink and use all the water on the earth's surface.
A.c and e B.a and d C.a,c and dD.b,d and e
