When imaginative men turn their eyes towards space and wonder whether life exists in any p

art of it, they may cheer themselves by remembering that life need not resemble closely the life that exists on Earth. Mars looks like the only planet where life like ours could exist, and even this is doubtful. But there may be other kinds of life based on other kinds of chemistry, and they may multiply on Venus or Jupiter. At least we cannot prove at present that they do not.

Even more interesting is the possibility that life on their planets may be in a more advanced stage of evolution. Present-day man is in a peculiar and probably temporary stage. His individual units retain a strong sense of personality. They are, in fact, still capable under favorable circumstances of leading individual lives. But man's societies are already sufficiently developed to have enormously more power and effectiveness

than the individuals have.

It is not likely that this transitional situation will continue very long on the evolutionary time scale. Fifty thousand year's from now man's societies may have become so close-knit that the individuals retain no sense of separate personality. Then little distinction will remain between the organic parts of the multiple organism and the inorganic parts (machines) that have been constructed by it. A million years further on man and his machines may have merged as closely as the muscles of the human body and nerve cells that set them in motion.

The explorers of space should be prepared for some' such situation. If they arrive on a foreign planet that has reached an advanced stage (and this is by no means impossible), they may find it being inhabited by a single large organism composed of many closely cooperating units.

The units may be "secondary"-machines created millions of years ago by a previous form. of life and given the will and ability to survive and reproduce. They may be built entirely of metals and other durable materials. If this is the case, they may be much more tolerant of their environment, multiplying under conditions that would destroy immediately any organism made of carbon compounds and dependent on the familiar car bon cycle.

Such creatures might be relics of a past age, many millions of years ago, when their planet was favorable to the origin of life, or they might be immigrants from a favored planet.

Humans on Earth today are characterized by______.

A．their existence as free and separate beings

B．their capability of living under favorable conditions

C．their great power and effectiveness

D．their strong desire for living in a close-knit society

第4题

There was a time when, if a lady got onto a crowded bus or train, a gentleman would im
mediately stand up and offer her his seat. Today a gentleman will probably look out of the window or hide behind his newspaper. Either way, the lady will have to stand until someone gets off.

You can' t entirely blame men for this change in manners. The days are gone when women could be treated as the weaker sex. A whole generation of women has grown up demanding equality with men; not just equality in jobs or education, but in social attitudes. Hold a door open for some women and you're likely to get an angry lecture on treating women as inferiors, unable to open doors for themselves. Take a girl out for a meal and she'll probably insist on paying her share of the bill.

It' s no wonder, then, that men have given up some of the gestures of politeness and consideration which they used to show towards women. On the other hand, man' s politeness is perhaps slowly being replaced by true consideration for the needs and feelings of women, so that men can see women as equal human beings.

1.What is replacing men' s gestures of politeness？()

A.More graceful politeness towards women

B.More consideration for women' s needs and feelings

C.More equal treatment to women in every respect

D.More impolite gestures of social behavior. to women

2.What can we learn from this passage？()

A.Men ought to make gestures of politeness towards women

B.Women ought to make gestures of politeness towards men

C.Women have achieved equality with men

D.Men are beginning to treat women as equal human beings

3.Which of the following statements is true？()

A.Men have become less and less polite to women

B.The women are thought of as the weaker sex

C.The women could not open doors for themselves

D.Men' s attitudes towards women are reasonable

4.What do gentlemen now do when a lady gets on a crowded bus or train.()

A.They will stand up reluctantly

B.They will offer her their seats after a while

C.They will pretend not to see her

D.They will get off the bus

5.Why are some women likely to get angry as a man holds the door open for them？()

A.Because the man should not hold the door open

B.Because they think they are looked down upon

C.Because they are treated too politely

D.Because men often offend women in this manner

In hot, dry lands, men found that they could eat meat that had dried while it was still on the bones. They later learned to cat meat into thin stops and hang it up to dry in the hot air

D.H. Lawrence was born in a working class family in 1885 when England was at the full deve
lopment of its industry. His father was a coal-miner, so he knew what it was like to be poor. But his mother straggled hard to help her children get better chances than his father had. Lawrence became a teacher, and so escaped the mining world of his father. But he never forgot it. He wrote many stories about the life of the miner's family, including his most famous novel Sons and Lovers, which is a portrait of Lawrence's own life. Many of his stories and novels are on men who work down the mines. He once said of the men in the coal mines: Here in this terrible hell, the men are most happy. He meant the comradeship of the miners, the fact that they lived simply, without wishes for power, without money, without health.

D.H. Lawrence was ______.

A．a coal-miner

B．a teacher of English

C．an English writer

D．anyone but a miner

The Great Wall is one of the wonders of the world that created by human beings! If you
come to China without climbing the Great Wall, it's just like going Paris without visiting the Eiffel Tower(埃菲尔铁塔); or going to Egypt without visiting the Pyramids(金字塔).Men often say, “He who does not reach the Great Wall is not a true man.”In fact, it began as independent walls for different states when it was first built, and did not become the “Great Wall” until the Qin Dynasty.However, the wall we see today, starting from Shanhaiguan Pass in the east to Jiayunguan Pass in the west, was mostly built during the Ming Dynasty.

In many stories on TV and in science-fiction books, men travel to faraway stars. They have
quick, easy journeys. But so far, men have been able to reach only the earth's own moon.

Suppose a man wanted to reach a distant star. Even if he traveled his whole life, he would have to move faster than the speed of light. Nothing can move that fast except light itself.

Strange things happen to an object when it moves rapidly. The object weighs more. An object moving at 86 percent of the speed of light is twice as heavy as it is at rest. A stick appears shorter. A clock runs more slowly. A man would not age so fast as he would on the earth.

Light travels more than 186, 000 miles a second, or about 11 million miles a minute. In one year, light travels six trillion(万亿) miles. That great distance is called a light-year. It is used to measure distances in space.

The star closest to our sun is Alpha Centrauri (半人马座a星). It is more than four lightyears away. If one traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But, even at that speed, he could not reach Alcaid (北斗星)in the handle of the Big Dipper. A one-way journey to Alcaid would take almost 200 years!

Why do we measure the distance in light-years instead of miles？

A．Units of light-years sound better.

B．Using light-years reduced the number of figures used.

C．We used to measure distance in light-years long ago.

D．We do not make mistakes when we use light-years.

第10题

Observe a child: any one will do. You will see that not a day passes in which he does not
find something or other to make him happy, though he may be in tears the next moment. Then look at a man: any one of us will do. You will notice that weeks and months can pass in which every day is greeted with nothing more than resignation, and endured with polite indifference. Indeed, most men are as miserable as sinners, though they are too bored to sin—perhaps their sin is their indifference. But it is true that they so seldom smile, that when they do we do not recognize their face, so distorted it is from the fixed mask we take for granted. And even then a man can not smile like a child, for a child smiles with his eyes, whereas a man smiles with his lips alone. It is not a smile, but a grin: something to do with humor, but little to do with happiness. And then, as anyone can see, there is a point(but who can define that point？)when a man becomes an old man, and then he will smile again. It would seem that happiness is something to do with simplicity, and that it is the ability to extract pleasure from the simplest things such as a peach stone, for instance.
