Where Has the Salt Come from?
Every now and then,we meet a fact about our earth that makes us feel strange and no
answer for the fact has yet been found.Such a fact is the existence of salt in the oceans.
How did it get there?
We simply do not know how the salt got into the ocean!We do know,of course,that
salt is water-soluble,and so passes into the oceans with rainwater.The salt of the earth's
surface is constantly being dissolved（溶解）and is passing into the ocean.
But we do not know whether this can explain the huge quantity of salt in oceans.If all
the oceans were dried up,enough salt would be left to build a wall 180 miles high and a
mile thick. Such a wall would reach once around the world at the Equator（赤道）!
The common salt that we all use is produced from seawater or the water of salt lakes,
from salt springs（源泉）and from deposits of rock salt. The concentration（浓度）of salt in
seawater ranges from about three percent to three-and-one-half percent. The Dead Sea,
which covers an area of about 340 square miles,contains about 11,600,000,000 tons of
salt!
On the average, a gallon（加仑）of seawater contains about a quarter of a pound of
salt.The beds of rock salt that are found in various parts of the world were all originally
formed by the evaporation（蒸发）of seawater millions of years ago. It is believed that the
thick rock-salt deposits were formed after about nine-tenth of theY volume of seawater had
been evaporated.
Most commercial salt is obtained from rock salt.The usual method is to drill wells（井）
down to the salt beds. Pure water is pumped down（抽进去）through a pipe. The water
dissolves the salt and it is forced through another pipe up to the surface.
A:Right
B:Wrong
C:Not mentioned

Passage Three
Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them; our purpose is to prepare them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough just to choose the first system of education one finds, or to continue with one's old system of education without examining it to see whether it is in fact suitable or not.
In many modern countries, it has for some time been fashionable to think that by free education for all—whether rich or poor, clever or stupid—one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider "low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.
But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor. We can live without education, but we will die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.
In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability, and secondly, we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.
44. Education is______.
A. a purpose
B. a means
C. fashionable
D. the first system

Where Has the Salt Come from?
Every now and then,we meet a fact about our earth that makes us feel strange and no
answer for the fact has yet been found.Such a fact is the existence of salt in the oceans.

第6题：
Most of us，when we reached our teens，started looking forward to the day when we would occupy places of our own，far from the confines of our families. We saw this moving away as a chance to strike out on our own，to grow，to spread out wings and experience freedom. At the same time，we regarded this independence as temporary-the thing to do until we found the perfect mate and married. Over the years，many millions of people have made this passage from one family to another，with just a brief，often nervous interval of independence in between. But recently，more and more people have begun to challenge the concept that living together is better than living alone. Being single is now accepted as an alternative lifestyle-one that is natural，rewarding，and complete. In fact，being single has become almost fashionable.
我们大多数人到了十几岁的时候，就开始向往有一天能有自己的独立空间，从而远离家庭的束缚。我们把离开家看做是独立生活、长大成人、展翅飞翔和体验自由的机会。但与此同时，我们认为这种独立只不过是在我们找到满意的伴侣并结婚之前的暂时的事情。这些年中，几百万人们都是这样从一个家庭到另一个家庭过来的，中间经历了一个短暂、并且常常是不知所措的独立阶段。但是最近，这种与人住在一起比独居更好的观念正开始受到越来越多的人们的挑战。独身现在被人们看做是生活方式的另一种选择-这种生活方式是合乎自然的，有意义的，而且是没有什么缺陷的。实际上，独身已经变得近乎流行起来了。

第8题：
B
The world is not only hungry，it is also thirsty for water． this may seem strange to you，since nearly 75% of the earth is covered with water． But about 97% of this water is sea water．Man can only drink and use the other 3% fresh water that comes from rivers，lakes，under-ground and other places． And we cannot even use all of that，because some of this fresh water has been made dirty．
At the moment，this small amount(数量) of fresh water is still enough for us． However，our need for water is getting greater and greater． Only if we take steps to solve this problem now，we can get away from a serious world water shortage later on． The people of the world cannot have an enjoyable life without enough clean water．
On one hand we should stop wasting this little water of ours，on the other hand we should find ways to reuse it，but this has not been done widely．
Today，in most large cities，water is used only once and it then returns to the sea or runs into underground places．lf we can make it clean again，it can be used once more just as if it were fresh from a spring．
But even if large cities reuse its water，we still would not have enough in the future． Where．could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh．
So if we take all these steps，we'll be in no danger of drying up!
( )26． Why does the writer say that the world is thirsty for water?
A． The amount of fresh water is really very small．
B． The people of the world waste too much water．
C． The people of the world have to drink a lot of water every day．
D． There are too many people in the world needing water．
26．A【解析】由第一段的描述可知，人类只有3%的、 淡水可以利用。
