There are great impediments to the general use of a standard in

pronunciation comparable to that existing in spelling.

(orthography). One is the fact that pronunciation is learnt

'naturally' and unconsciously, and orthography is learnt 【B1】______

deliberately and consciously. Large numbers of us, in fact,

remain throughout our lives quite unconscious with what 【B2】______

our speech sounds like when we speak out, and it often 【B3】______

comes as a shock when we firstly hear a recording of ourselves. 【B4】______

It is not a voice we recognize at once, whereas our own handwriting

is something which we almost always know. We begin the 'natural' 【B5】______

learning of pronunciation long before we start learning to read or

write, and in our early years we went on unconsciously imitating and 【B6】______

practicing the pronunciation of those around us for many more hours

per every day than we ever have to spend learning even our difficult 【B7】______

English spelling. This is 'natural', therefore, that our speech-sounds 【B8】______

should be those of our immediate circle；after all, as we have seen,

speech operates as a means of holding a community and 【B9】______

giving a sense of 'belonging'. We learn quite early to recognize a

'stranger', someone who speaks with an accent of a different

community — perhaps only a few miles far. 【B10】______

e will soar to 5 billion within the next few years. Shell said the energy resource supply of China will double around 2020. The country will need more foreign capital for upstream petroleum products, and natural gas projects. Shell is quite willing to take part in the projects. Shell plans to cooperate with PetroChina in the west-east gas transmission project. The total investment will reach USD 8 billion. Shell cooperated with China National Offshore Oil last year in Nanhai Petroleum Chemical project.

How much has Shell invested in China so far？

A．1.6 billion USD

B．1.6 million USD

C．5 billion USD

D．5 million USD

The term biological clock is applied to the means, which living things 【M1】______

adjust their activity patterns, without any obvious cue, the time of day, or 【M2】______

the month, or the year. They are affected but little, if at all, by drugs,

chemical, or wide temperature differences—factors may alter substantially 【M3】______

the rates of all ordinary processes of the body.

The nature of the biological clocks mechanism is still a mystery. Two 【M4】______

quite different theories have been advanced to account to them. According 【M5】______

to the first of these theories, each individual have evolved, aided by natural

selection, an adaptation to the rhythmic environment. It has now 【M6】______

become independence on the environment. According to this view, the clocks 【M7】______

are not perfect timers. They require regular corrections by the natural light

and tide cycles and the changed lengths of the day throughout the year. 【M8】______

The other theory holds up living things react continuously to their 【M9】______

rhythmic physical environment. The setting of their biological clocks,

therefore, involves a constant adjustment to subtle clocks are potential 【M10】______

perfect timers.

rthern Hemispheres(地球的半球)shows a(n)【C1】______trend in average temperatures over the【C2】______hundred years. At the moment most scientists are not prepared to stick their necks out and【C3】______a cause to this trend. It is possible that it represents a natural climatic change caused by a【C4】______increase in the sun's radiation output. But these same scientists are【C5】______aware that recent temperature changes are at the limit of known natural【C6】______: it seems increasingly likely that the cause is a(n)【C7】______greenhouse effect.

The basic theory of the greenhouse effect is quite simple. The earth's atmosphere consists【C8】______of oxygen and nitrogen,【C9】______there are small concentrations of various "greenhouse" gases-【C10】______carbon dioxide, water vapor, and methane(沼气)-- which play a very important role in【C11】______the planet's "heat balance". As their name suggests these gases have a similar effect on glass in a greenhouse: They let heat from the sun【C12】______, and keep it in.

The atmosphere is more or less transparent to the【C13】______solar radiation which warms the earth(ground or oceans)on which it falls.【C14】______it has been heated, the earth is warmer than space and gives【C15】______energy in the form. of in visible long-wave infrared radiation. This【C16】______for nighttime cooling. Greenhouse gases【C17】______some of this long-wave radiation, and reradiate it in the lower atmosphere.

The gases【C18】______act rather like a blanket by preventing some infrared radiation from leaving the earth-atmosphere system.【C19】______certain limits, the more greenhouse gases present, the more infrared radiation will become【C20】______, and the higher the surface temperature of the earth.

adequately met？ Sociologists and psychologists are conducting experiments on rats to try to determine the effect of overcrowded conditions on man. Recent studies have shown that the behavior. of rats is greatly affected by space. If rats have adequate living space, they eat well, sleep well, and reproduce well.

However, if their living conditions become too crowded, their behavior. patterns and even their health perceptibly change. They cannot sleep or eat well, and signs of fear and tension become obvious. The more crowded they are, the more they tend to bite each other and even kill each other. Thus for rats, population and violence are directly related. Is this a natural law for human society as well？ Is adequate space not only desirable, but also essential for human survival？

This passage is mainly about ______.

A.living space and behavior

B.population and living conditions

C.interesting experiments on rats

D.a natural law for human society

What is the purpose of the experiments described in the passage？A.To determine how much living space a rat needs.

B.To see what happens when rats live in a limited space.

C.To know the likely effects of inadequate living space on human beings.

D.To find out the relationship between population and living conditions.

How would rats behave when their living conditions become too crowded？A.They eat a lot and become friendly to others.

B.They sleep little and act quite peacefully.

C.They eat little but sleep soundly.

D.They become nervous and tend to be war-like.

The passage suggests that overcrowded conditions ______.A.are directly related with population

B.may cause an increase in violence

C.may lead to high birth rate

D.may bring about pollution problems

el of the daydream. By picturing quite unusually happy and glamorous people whose success in either career or sexual terms, or both, is obvious, adverts construct an imaginary world in which the reader is able to make come true those desires which remain unsatisfied in his or her everyday life.

An advert for a science fiction magazine is unusually explicit about this. In addition to the primary use value of the magazine, the reader is promised access to a wonderful universe through the product-access to other mysterious and tantalizing worlds and epochs, the realms of the imagination. When studying advertising, it is therefore unreasonable to expect readers to decipher adverts as factual statements about reality. Most adverts are just too meager in informative content and too rich in emotional suggestive detail to be read literally. If people read them literally, they would soon be forced to realize their error when the glamorous promises held out by the adverts didn't materialize.

The average consumer is not surprised that his purchase of the commodity does not redeem the promise of the advertisement, for this is what he is used to in life: The individual's pursuit of happiness and success is usually in vain. But the fantasy is his to keep; in his dream world he enjoys a "future endlessly deferred" .

The Estivalia advert company is quite explicit about the fact that advertising shows us not reality, but a fantasy; it does so by openly admitting the daydream but in a way which insists on the existence of a bridge linking daydream to reality—Estivalia, which is "for daydream believers", those who refuse to give up trying to make the hazy ideal of natural beauty and harmony come true.

If adverts function on the daydream level, it clearly becomes inadequate to merely condemn advertising for channeling readers' attention and desires towards unrealistic, paradisiacal (天堂似的) nowhere land. Advertising certainly does that, but in order for people to find it relevant, the Utopia(乌托邦)visualized in adverts must be linked to our surrounding reality by a causal connection.

The people in adverts are in most cases______.

A．glamorous

B．arrogant

C．obvious

D．sexy

ot only of the young men who are its pupils and novices in various lines of study, but also of young men with older men, with veterans and professionals in the great undertaking of learning, of teachers with pupils, outside the classroom as well as inside it. No one is successfully educated within the walls of any particular classroom or laboratory or museum; and no amount of association, however close and familiar and delightful, between mere beginners can ever produce the sort of enlightenment which the young lad gets when he first begins to catch the infection of learning. The trouble with most of our colleges nowadays is that the faculty of the college live one life and the undergraduates quite a different one. They constitute two communities. The life of the undergraduates is not touched with the personal influence of the teachers: life among the teachers is not touched by the personal impressions which should come from frequent and intimate contact with undergraduates. This separation need not exist, and, in the college of the ideal university, would not exist.

It is perfectly possible to organize the life of our colleges in such a way that students and teachers alike will take part in it; in such a way that a perfectly natural daily intercourse will be established between them; and it is only by such an organization that they can be given real vitality as places of serious training, be made communities in which youngsters will come fully to realize how interesting intellectual work is, how vital, how important, how closely associated with all modern achievement--only by such an organization that study can be made to seem part of life itself. Lectures often seem very formal and empty things; recitations generally prove very dull and unrewarding. It is in conversation and natural intercourse with scholars chiefly that you find how lively knowledge is, how it ties into everything that is interesting and important, how intimate a part it is of everything that is "practical" and connected with the world. Men are not always made thoughtful by books; but they are generally made thoughtful by association with men who think.

The present and most pressing problem of our university authorities is to bring about this vital association for the benefit of the novices of the university world, the undergraduates. Classroom methods are thorough enough; competent scholars already lecture and set tasks and superintend their performance; but the life of the average undergraduate outside the classroom and other stated appointments with his instructors is not very much affected by his studies, and is entirely dissociated from intellectual interests.

An ideal college ______.

A．should have mature, experienced and professional men on its staff

B．should be managed by experienced scholars

C．should be managed by experienced scholars and energetic young men

D．should see tight, harmonious connection between the experienced and the inexperienced
