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

第4题:

The water we drink and use is running short in the world.We all have to learn how to stop wasting our limited water.One of the steps we should take is to find ways of reusing it.Experiments have already been done in this field.
Today in most large cities,fresh water is used only once,then it runs into waste system.But it is possible to pipe the used water to a purifying factory.There it can be filtered and treated with chemicals so that it can be used again,just as it were fresh from a spring.
But even if every large city purified and reused its water,we still would not have enough.Then we could turn to the oceans.All we’d have to do to make use of the seawater on earth is to get rid of the salt.This process is called desalinization,and it is already in use in many parts of the world.
The way to stop wasting our limited water is to________.

A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater

第8题:

We can draw a conclusion from the text that______.

A) oil-price shocks are less shocking now

B) inflation seems irrelevant to oil -price shocks

C) energy conservation can keep down the oil prices

D) the price rise of crude leads to the shrinking of heavy industry


正确答案:A
答案:A
[试题分析]文章主旨题。
[详细解答]题干要求考生识别文章的中心思想,即“我们能从文章中得出什么结论”。文章一开始提出最近石油价格大幅上涨,会不会像前两次油价暴涨一样造成经济衰退。但接下来它又说这次油价上涨的影响不会像以前那样严重,并说出了几点原因:(1)原油价格只占汽油价格的一小部分,(2)发达国家对石油的依赖性不如从前,(3)并没有同时发生商品总价格上涨和全球需求旺盛的现象。因此,文章的中心思想是A选项“oil-price shocks are less shocking now”(现在的油价暴涨并不可怕)。B选项“iafla tion seems irrelevant to oil-price shocks”(通货膨胀与油价暴涨无关),C选项"energy conservation can keep down the oil prices"(能源储备能够压抑油价)和D选项“the price rise of crude leads to the shrinking of heavy industry”(原油价格上涨导致重工业的萎缩)都不是全文重点讨论的内容。
