economic advance has been remarkable. During this relatively short period of time, greater changes in people's living conditions have occurred than in the thousands of years which preceded.

During the past 200 years the world population has increased 6 times, the annual world output has increased 80 times, and the distance a person can travel has gone up 1,000 times. There has also been much recent progress in art, culture, learning, and science. Such changes have led to a high rate of production and growth of the economy.

Economists fear that within the next 100 to 150 years, the earth's resources will become very scarce. Their fears are partly justified, but we should not be afraid. Industrial civilization adapts to new knowledge. By advancing knowledge, we not only create new forms of resources, but we also find ways to economize their use. Advanced modern knowledge can feed the hungry people of the world and improve their standard of living.

The figures in the second paragraph are used for the following purposes EXCEPT______.

A．prediction.

B．contrast.

C．definition.

D．explanation.

an object, but it is not really fixed at all. If you could take a one pound packet of butter 4,000 miles out from the earth, it would weigh only a quarter of a pound.

Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space？ The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center (in other words the radius[半径] of the earth is 4,000 miles). When we took the butter 4,000 miles out, it was 8,000 miles from the center, which is twice the distance.

If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (成三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four ) and so on.

The best title for this passage is______.

A．The Earth Weight

B．Weight in Space

C．Changing Weight on the Earth

D．Weight on and off the Earth

should be able to notice a number of significant truths. The history of our language has always been a history of constant change -- at times a slow, almost unnoticeable change, at other times a violent collision between two languages. Our language has always been a living growing organism, it has never been static.

Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans. At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty.

As we consider our changing language, we should note here two developments that are of special and immediate importance to us.

One is that since the time of the Anglo-Saxons(盎格鲁撒克逊人)there has been an almost complete reversal of the different devices for showing the relationship of words in a sentence. Anglo-Saxon(old English)was a language of many inflections. Modern English has few inflections. We must now depend largely on word order and function words to convey the meanings that the older language did by means of changes in the forms of words. Function words, you should understand, are words such as prepositions, conjunctions, and a few others that are used primarily to show relationships among other words. A few inflections, however, have survived. And when some word inflections come into conflict with word order, there may be trouble for the users of the language, as we shall see later when we turn our attention to such matters as WHO or WHOM and ME or I.

The second fact we must consider is that as language itself changes, our attitudes toward language forms change also. The 18th century, for example, produced from various sources a tendency to fix the language into patterns not always set in and grew, until at the present time there is a strong tendency to restudy and re-evaluate language practices in terms of the ways in which people speak and write.

In the past 100 years of development, the English language ______.

A．has been changing violently all the time

B．has been static all the time

C．has been changing slightly sometimes

D．has been static sometimes
