It is difficult to imagine what life would be like without memory. （78)The meanings of tho

It is difficult to imagine what life would be like without memory. (78)The meanings of thou- sands of everyday perceptions, the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.

Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involving any change in the way an animal typically behaves. (79)Memory is involved when a rat gives up eating grain be- cause he has sniffed something suspicious in the grain pile. Memory is also involved when a six- year-old child learns to swing a baseball bat.

Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 " words" —ready for instant use. An average U.S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for ex- ample, the number of faces and places that the teenager can recognize on sight.

The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person' s memory is in terms of words and combinations of words.

According to the passage, memory is considered to be ______.

A．the basis for decision making and problem solving

B．an ability to store experiences for future use

C．an intelligence typically possessed by human beings

D．the data mainly consisting of words and combinations of words

Increasingly, over the past ten years, people—especially young people—have become aware of

the need to change their eating habits, because much of the food they eat, particularly foods, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming to- day.

Natural foods, for example, vegetables, fruits and grains which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming areas.

Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for ex- ample, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.

There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar, this is actually a non-essential food! Although a natural alternative, such as honey, can be used to sweeten food if this is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be an additive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form. of calories. There are no vitamins in it, no minerals and no fibre.

It is significant that nowadays fibre is considered to be an important part of a healthy diet. In white bread, for example, the fibre has been removed. But it is present in unrefined flour and of course in vegetable. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetable, certain diseases are comparatively rare. Hence the emphasis placed on the eating of wholemeal bread and more vegetables by modern experts on healthy eating.

Recently, some people are interested in natural foods because ______.

A．these foods are fresh and sweet

B．they want to change their eating habits

C．these foods do not contain chemical additives and have not been affected by chemical fertilizers

D．they don't like the processed foods

The Fourteenth Amendment to the United States Constitution, ratified in 1868, prohibits st

ate governments from denying citizens the "equal protection of the laws". Although precisely what the framers of the amendment meant by this equal protection clause remains unclear, all interpreters agree that the framers' immediate objective was to provide a constitutional warrant for the Civil Rights Act of 1866, which guaranteed the citizenship of all persons born in the United States and subject to United States jurisdiction. This declaration, which was echoed in the text of the Fourteenth Amendment, was designed primarily to counter the Supreme Court's ruling in Dred Scott v. Sanford that Black people in the United States could be denied citizenship. The act was vetoed by President An- drew Johnson, who argued that the Thirteenth Amendment, which abolished slavery, did not provide Congress with authority, to extend citizenship and equal protection the freed slaves. Although Congress promptly overrode Johnson's veto, supporters of the act sought to ensure its constitutional foundations with the passage of the Fourteenth Amendment.

The broad language of the amendment strongly suggests that its framers were proposing to write into the Constitution not a laundry list of specific civil rights but a principle of equal citizenship that forbids organized society from treating any individual as a member of an inferior class. Yet for the first eight decades of the amendment's existence, the Supreme Court's interpretation of the amendment betrayed this ideal of equality. In the Civil Rights Cases of 1883, for example, the Court in- vented the "state action" limitation, which asserts that "private" decisions by owners of public accommodations and other commercial businesses to segregate their facilities are insulated from file reach of the Fourteenth Amendment' s guarantee of equal protection under the law. After the Second World War, a judicial climate more hospitable to equal protection claims culminated in the Supreme Court's ruling in Brown V. Broad of Education that racially segregated schools violated the equal protection clause of the Fourteenth Amendment.

According to this passage, which of the following is correct？

A．By presenting a list of specific rights, framers of the Fourteenth Amendment were attempting to provide a constitutional basis for abroad judicial protection of the principle of equal citizenship.

B．Interpreters of the Fourteenth Amendment have not reached consensus with regard to what its framers meant by the equal protection clause.

C．Not until after the Second World War did the Supreme Court begin to interpret the Fourteenth Amendment in a manner consistent with the principle of equal citizenship that it ex- presses.

D．The framers of the Fourteenth Amendment were aware that the phrase "equal protection of the laws" had broad implications.

I am not sure that I can draw an exact line between wit and humor （perhaps the distinction

I am not sure that I can draw an exact line between wit and humor (perhaps the distinction is so subtle that only those persons can decide who have long white beards), but even an ignorant person may ex- press an opinion in this matter.

I am quite positive that humor is the more comfortable and livable quality, for humorous persons, if their gift is genuine and not a mere shine upon the surface, are always agreeable companions. They have pleasant mouths turned up at the corners, to which the great Master of Marionettes has fixed the strings and he holds them in his nimblest fingers to twitch them at the slightest jest. But the mouth of a merely witty man is hard and sour. Nor is the flash from a witty man always comforting, but a humorous man radiates a general pleasure.

I admire wit, but I have no real liking for it; it has been too often employed against me, whereas humor is always an ally. It never points an impertinent linger into my defects. A wit's tongue, however, is as sharp as a donkey's stick—I may gallop the faster for its prodding, but the touch behind is too persuasive for any comfort.

Wit is a lean creature with a sharp inquiring nose, whereas humor has a kindly eye and a comfortable girth. Wit has a better voice in a solo, but humor comes into the chorus best. Wit keeps the season's fashions and is precise in the phrases and judgments of the day, but humor is concerned with homely eternal things.

The distinction between wit and humor is______.

A．of no particular importance

B．solely a matter of opinion

C．subtle

D．exact and important

第10题

根据下面内容，回答下列各题： Coffee is worth approximately $ 50-60bn per annum in terms of w

orld sales. It is a truly international commodity, and today more than 50 countries in the world grow coffee beans. (0)________13 ICO consists of61 governments, 43 of which are exporters and 18 of which are importers. The organi- zation helps coffee producers and promotes coffee consumption worldwide. ICO esti- mates that world production next year will reach 97. 5 million bags, ll. 3 million bags higher than the current year. (8)________ As the largest producing country, Brazil is par- ticularly important in the coffee world. In1994 Brazil was responsible for 25% of world production, Colombia was next with13.4%, Indonesia had 7.5%, Mexico4. 7%, Guatemala 3.8% and Ethiopia and Vietnam were equal with 3.4%. Coffee is a tough crop, and can be grown in areas where it is difficult or impossible to grow other crops. (9 )________ However, disease is always a problem for coffee production, as we can see in some parts of South America at the moment. ICO is active in educating farmers about avoiding disease and dealing with problems when they occur. The distribution chain varies from country to country, explains Pablo Dubois. In most countries the smaller farmers sell their crop to a local trader, who then sells it on to ex- porters. There are, however, other distribu- tion systems. (10 )________ Some countries, like Vietnam, have special government mar- keting organizations for coffee. Coffee prices often vary greatly from one year to the next. In 1997, for example there was a large rise in the world price, which was immediately felt by the consumer. Rising prices always result in a drop in sales, which will have a bad effect on those developing countries which are highly dependent on foreign exchange from coffee exports. (11 )________ In the opinion of Pablo Dubois, the biggest problem for his organization is to create greater consumer awareness of the different varieties of coffee and different ways of preparing it. (12 ) ________ICO is therefore concentrating its promotional activities on Russia and China. It is also encouraging environmentally friendly coffee production, and last years seminar on coffee and the environment created a lot of interest. The future looks bright for the coffee industry. It is estimated that consumption over the next few years will continue to rise steadily. New markets like Eastern Europe and China are expected to develop fast. A．As a result, the membership now represents 94% of all exporters and 60% of all importers. B．In some of these countries, this can amount to as much as 50% of all export earnings. C．In North America, most consumers already have above-average knowledge of the range available. D．For example, frost and wind are particularly damaging to coffee crops. E Larger coffee growers, for example, frequently export directly. F．The main reason for this is higher Brazilian output as production recovers from weather damage to crops. G．It is cultivated in mountain regions which can only be reached by animal transport,and in other difficult areas where modern agricultural equipment cannot be used. __________
