There was one thought that air pollution affected only the area immediately around large c

ities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. (76)On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a "greenhouse effect"—conserving heat reflected from the earth and raising the world' s average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.

(77) Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth' s temperature—a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top fanning areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world' s temperature will stay about the same as it is now.

As pointed out at the beginning of the passage, people used to think that air pollution ______.

A.caused widespread damage in the countryside

B.affected the entire eastern half of the United States

C.had damaging effect on health

D.existed merely in urban and industries areas

Many people who work in London prefer to live outside it, and to go in to their office
s or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.

One advantage of living outside London is that houses are cheaper.Even a small flat in London without a garden costs quite a lot to rent.With the same money, one can get a little house in the country with a garden of one's own.

Then, in the country one can really get away from the noise and hurry of busy working lives.Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country.If one likes gardens, one can spend one's free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden.Then, when the flowers and vegetables come up, one has got the reward together with those who have shared the secret of Nature.

Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants.Such people would feel that their life was not worth living if they had to live it outside London.An occasional walk in one of the parks and a fortnight's two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.

1、Which of the following statements is NOT true?_________

A.People who love Nature prefer to live outside the city

B.People who work in London prefer to live in the country

C.Some people enjoying city life prefer to work and live inside London

A.getting a small flat with a garden

3、When the garden is in blossom, it means that one ________ has been rewarded.

A.living in the country

B.having spent time working in the garden

C.having a garden of his own

D.having been digging, planting and watering

4、People who think happiness lies in the town would feel that _______ if they had to liveoutside London.

I was taken by a friend one afternoon to a theatre. When the curtain was raised, the stage
was perfectly empty save for tall grey curtains which enclosed it on all sides, and presently through the thick folds of those curtains children came dancing in, singly, or in pairs, till a whole troop of ten or twelve were assembled. They were all girls; none, I think more than fourteen years old, one or two certainly not more than eight. They wore but little clothing, their legs, feet and arms being quite bare. Their hair, too, was unbound; and their faces, grave and smiling, were so utterly dear and joyful, that in looking on them one felt transported to some Garden of Hesperides, a where self was not, and the spirit floated in pure ether. Some of these children were fair and rounded, others dark and elf-like; but one and all looked entirely happy, and quite unself-conscious, giving no impression of artifice, though they had evidently had the highest and most careful training. Each flight and whirling movement seemed conceived there and then out of the joy of being—dancing had surely never been a labour to them, either in rehearsal or performance. There was no tiptoeing and posturing, no hopeless muscular achievement; all was rhythm, music, light, air, and above all things, happiness. Smiles and love had gone to the fashioning of their performance; and smiles and love shone from every one of their faces and from the clever white turnings of their limbs.

Amongst them—though all were delightful—there were two who especially riveted my attention. The first of these two was the tallest of all the children, a dark thin girl, in whose every expression and movement there was a kind of grave, fiery love.

During one of the many dances, it fell to her to be the pursuer of a fair child, whose movements had a very strange soft charm; and this chase, which was like the hovering of a dragonfly round some water lily, or the wooing of a moonbeam by the June night, had in it a most magical sweet passion. That dark, tender huntress, so full of fire and yearning, had the queerest power of symbolising all longing, and moving one’s heart In her, pursuing her white love with such wistful fervour, and ever arrested at the very moment of conquest, one seemed to see the great secret force that hunts through the world, on and on, tragically unresting, immortally sweet.

The other child who particularly enhanced me was the smallest but one, a brown-haired fairy crowned with a haft moon of white flowers, who wore a scanty little rose-petal-coloured shift that floated about her in the most delightful fashion. She danced as never child danced. Every inch of her small bead and body was full of the sacred fire of motion; and in her little pas seul she seemed to be the very spirit of movement. One felt that Joy had flown down, and was inhabiting there; one heard the rippling of Joy’s laughter. And, indeed, through all the theatre had risen a rustling and whispering; and sudden bursts of laughing rapture.

I looked at my friend; he was trying stealthily to remove something from his eyes with a finger. And to myself the stage seemed very misty, and all things in the world lovable; as though that dancing fairy had touched them with tender fire, and made them golden.

God knows where she got that power of bringing joy to our dry hearts: God knows how long she will keep it! But that little flying Love had in her the quality that lie deep in colour, in music, in the wind, and the sun, and in certain great works of art—the power to see the heart free from every barrier, and flood it with delight.

From this passage, it can be inferred that

A.the dancing girls are an very beautiful.

B.the girls come from all over the world.

C.the two tallest girls are the outstanding dancers.

D.the girls' performance is very successful.

Like most people, I was brought up to look upon life as a process of getting. It was not u
ntil in my late thirties that I made this important discovery: giving away makes life so much more exciting. You need not worry if you lack money. This is how I experimented with giving away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation. " Wasn't it you that wrote us that letter a year ago about delivering a special delivery to your home? " I said yes. "Well, you certainly are going to have a box in this post office if we have to make one for you. You don't know what a letter like that means to us. We usually get nothing but complaints.

From the passage, we understand that______.

A.the author did not understand the importance of giving until he was in late thirties

B.the author was like most people who were mostly receivers rather than givers

C.the author received the same education as most people during his childhood

D.the author liked most people as they looked upon life as a process of getting

Some psychologists maintain that mental acts such as thinking are not performed in the bra
in alone, but that one's muscles also participate. It may be said that we think with our muscles in somewhat the same way that we listen to music with our bodies.

You surely are not surprised to be told that you usually listen to music not only with your ears but with your whole body. Few people can listen to music that is more or less familiar without moving their body or more specifically, some part of their body. Often when one listens to a symphonic concert on the radio, he is tempted to direct the orchestra even though he knows them is a competent conductor on the job.

Strange as this behavior. may be, there is a very good mason for it. One cannot derive all possible enjoyment from music unless he participates, so to speak, in its performance. The listener "feels" himself into the music with more or less noticeable motions of his body.

The muscles of the body actually participate in the mental process of thinking in the same way, but this participation is less obvious because it is less noticeable.

Some psychologists maintain that thinking is ______.

A.not a mental process

B.more of a physical process than a mental action

C.a process that involves our entire bodies

D.a process that involves the muscles as well as the brain

One of the qualities that most people admire in others is the willingness to admit one's m
istakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that."

I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain store in the neighborhood where I grew up; and he asked me if I remembered the egg cartons (in many countries, eggs are sold by the dozen and are put in cartons). Then he related an incident(event, matter)and I began to remember unclearly the incident he was describing.

I was about eight years old at the time. I went into the store with my mother to do some shopping. On that particular day, I must have found my way to the food department where the incident took place.

There must have been a special sale on eggs that day because there were lots of eggs in dozen and half-dozen cartons. The cartons were put three or four feet high. I must have stopped in front of the piles of egg cartons. Just then a woman came by pushing her shopping cart and knocked off the cartons. For some reason, I decided it was up to me to put the eggs back together, so I went to work.

The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees looking at some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the one who just did it. He severely reprimanded me and wanted me to pay for any broken eggs. I tried to explain, but it did no good. Even though I quickly forgot all about the incident, it is plain that the manager did not.

According to this passage, many people will have a good opinion of those who ______.

A.have never made any mistakes

B.often make mistakes but correct them in no time

C.admit their mistakes

D.forget other people's mistakes easily

Of the six outer planets, Mars, commonly called the Red Planet, is the closest to Earth. M
ars, 4,200 miles in diameter and 55% of the size of the Earth, is 34,600,000 miles from the Earth, and 141,000,000 miles from the Sun. It takes this planet, along 0with its two moons, Phoboes and Deimos, 1.88 years to circle, the Sun, compared to 365 days from the Earth.

For many years, Mars had been thought of as the planet with the man made canals, supposedly discovered by an Italian astronomer, Schiaparelli, in 1877. With the United States spacecraft Viking I's landing on 'Mars in 1976, the man-made canal theory was proven to be only a myth.

Viking I, after landing on the soil of Mars, performed many scientific experiments and took numerous pictures. The pictures showed that the red color of the planet is due to the reddish, rocky Martian soil. No biological life was found, though it had been speculated by many scientists. The Viking al so monitored many weather changes including violent dust storms. Some water vapor, polar ice and permafrost were found, indicating that at one time there were significant quantities of water on this distant planet. Evidence collected by the spacecraft shows some present volcanic action, though the volcanoes are believed to be dormant, if not extinct.

Which of the following is true?

A.Mars is larger than the Earth.

B.Mars had Viking as its moon.

C.Martian soil is brownish rod.

D.It takes longer for Mars to circle the Sun than it takes the Earth.

根据以下内容回答下列各题, Banks are not ordinarily prepared to pay out all accounts; they
rely on depositors (储户) not to demand payment all at the same time. If depositors should come to fear that a bank is not safe, that it cannot pay off all its depositors, then that fear might cause all the depositors to appear on the same day. If they did, the bank could not pay all accounts. However, if they did not all appear at once, then there would always be enough money to pay those who wanted their money when they wanted it. Mrs. Elsie Vaught has told us of a terrifying bank run that she experienced. One day in December of 1925 several banks failed to open in a city where Mrs. Vaught lived. The other banks expected a run the next day, and so the officers of the bank in which Mrs Vaught worked as a teller had enough money on hand to pay off their depositors. The officers simply told the tellers to pay on demand. The next morning a crowd gathered in the bank and on the sidewalk outside. The length of the line made many think that the bank could not possibly pay off everyone. People began to push and then to fight for places near the tellers windows, The power of the panic atmosphere was such that two tellers, though they knew that the bank was quite all right and could pay all depositors, drew their own money from the bank. Mrs Vaught says that she had difficulty keeping herself from doing the same. A bank run happens when _______.

A.a bank is closed for one or more days

B.too many depositors try to draw out their money at one time

C.there is not enough money to pay all its depositors at one time

D.tellers of a bank take their own money from the bank
