Our surroundings are being polluted
faster than ever and it seems that people cannot prevent it. Time is bringing us
more people, and more people will bring us more industry, more cars, larger
cities, and the growing use of man-made materials. What can
explain and settle this problem? The fact is that pollution is caused by man—by
his desire for a modern way of life. We make "increasing industrialization" as
our first aim. So we are often ready to offer everything: clean air, pure water,
good food, our health and the future of our children. There is a constant flow
of people from the country-side into the cities, eager for the achievements of
our modern society. But as our technological achievements have grown in the last
20 years, pollution has become a serious problem. Isn't it time
we stopped to ask ourselves where we are going—and why? It makes one think of
the story about the pilot who told his passengers over the loudspeaker," I've
some good news and some bad news. The good news is that we're making rapid
progress at 530 miles per hour. The bad news is that we are lost and don't know
where we're going." The sad fact is that this becomes a true story when speaking
of our modern society.

Now that man has actually landed on the
surface of the moon, he has learned many new things about it. But one thing man
knew before he ever reached the moon was that there was no life on it.
There is no atmosphere on the moon. The lack of air means that the moon is
not protected from any of the sun's rays. The sun sends out heat and light
radiation (辐射). Life on the earth depends on heat and light. But the sun also
sends out dangerous kinds of radiation. The earth's atmosphere protects us from
most of them. On the moon, however, there is no atmosphere to stop the
radiation. All the sun's rays beat down on the surface of the moon.
Because there is no atmosphere, the moon's surface is either extremely hot
or extremely cold. As the moon circles around the earth, the side of it that is
lighted up by the sun becomes very hot. The temperature there reaches more than
300 degrees Fahrenheit (华氏温度). This is hotter than boiling water. The hot
{{U}}lunar{{/U}} day lasts two weeks. It is followed by a night that is also two
weeks long. At night the temperature drops to about 260 degrees below zero
Fahrenheit. "This is more than twice as cold as temperatures reached at the
earth's South Pole. Under these conditions, no form of life that we know of here
on the earth could exist on the moon.

In ancient (古代) time the most important
examinations were spoken, not written. In the schools of ancient Greece and
Rome, testing usually consisted of saying poetry aloud or giving
speeches. In the European universities of the Middle Ages,
students who were working for advanced degrees had to discuss questions in their
field of study of the subject. This custom exists today as part of the work of
testing candidates (候选人) for a master's or doctor's degree.
Generally, however, modern examinations are written. Two types of tests
are commonly used in modern schools. The first type is sometimes called an
objective (客观性) test, it is intended to deal with facts, not personal opinions.
To make up an objective test, the teacher writes a series of questions, each of
which has only one correct answer. Along with each question the teacher writes
the correct answer and also three statements that look like answers to students
who have not learned the material properly. The student has just
one task: he must recognize the correct answer and copy its letter or number on
his examination paper. For testing a student's memory of facts
and details, the objective test has advantages. It can find out a great deal
about the student's range of knowledge. For testing some kinds
of learning, however, such a test is not very satisfactory. A lucky student may
guess the correct answer without really knowing the
material.

单选题Today anyone will accept money in exchange for goods and services. People use money to buy food, furniture, books, bicycles and hundreds of other things they need or want. When they work, they usually get paid in money.
Most of the money today is made of metal or paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money. In Chinese history, cloth and knives were used. In the Philippine Islands, rice was used as money for a long tie. Elephant tusks, monkey tails, and salt were used as money in parts of Africa. Cattle were one of the earliest kinds of money. Other animals were used as money, too.
The first metal coins were made in China. They were round and had a square hole in the center. People strung them together and carried them from place to place. Different countries have used different metals and designs for their money. The first coins in England were made of tin. Sweden and Russia used copper to make their money, Later, countries began to make coins of gold and silver.
But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than the paper money used today.
Money has had an interesting history from the days of shell money until today.
