Geologists have been studying volcanoes for a long time. Though they have learned a great deal, they still have not discovered the cause of volcanic action. They know that the inside of the earth is very hot, but they are not sure exactly what causes the great heat. Some geologists have thought that the heat is caused by the great pressure of the earth's outer layers. Or the heat may be left from the time when the earth was formed. During the last sixty years scientists have learned about radium, uranium, thorium, and other radioactive elements. These give out heat all the time as they change into other elements. Many scientists now believe that much of the heat inside the earth is produced by radioactive elements.

Whatever the cause of the heat may be, we do know that the earth gets hotter the farther down we dig. In deep mines and oil wells the temperature rises about 1 F for each 50 feet. At this rate the temperature 40 miles below the earth' s surface would be over 4,000 F, This is much hotter than necessary to melt rock. However, the pressure of the rock above keeps most materials from melting at their usual melting points. Geologists believe that the rock deep in the earth may be plastic, or puttylike. In other words, the rock yields slowly to pressure but is not liquid. But if some change in the earth's crust releases the pressure, the rock melts. Then the hot, liquid rock can move up toward the surface.

When the melted rock works its way close to earth's crust, a volcano may be formed. The melted rock often contains steam and other gases under great pressure. If the rock above gives way, the pressure is released. Then the sudden expansion of the gases causes explosions. Theses blow the melted rock into pieces of different sizes and shoot them high in the air. Here they cool and harden into volcanic ash and cinders. Some of the material falls around the hole made in the earth's surface. The melted rock may keep on rising and pour out as lava. In this way, volcanic ash, cinders and lava build up the cone-shaped mountains that we call volcanoes.

The subject of this passage is the______.

A．formation of volcanoes

B．results of volcanic action

C．work of geologists

D．interior of the earth

A four-year study by sociologists at The University of Manchester has found that women are much likely than men to【M1】______ make deep and lasting friendships. The investigation into social networks by the Universitys Research Centre for Socio-Cultural Change found that men are more fickle and calculating about who they should be friends. Women, on the other hand, stand by their【M2】______ friends through thick and thin. Adding to the bad news for male prestige, the study confirms the stereotype which men are likely to【M3】______ base their friendship on social drinking. Of the 10,000 individuals studying who took part in the 1992【M4】______ to 2002 British Household Panel Surveys, women are much more likely to stay with the same friends. Single people, elder people【M5】______ and white collar workers are also good at paring up. Middle class people are more likely to cast their net of friendship far more【M6】______ wider, or the working class tend to stick to their own kind.【M7】______ Dr Gindo Tampubolon said the findings to female friendship【M8】______ were double significant because the data suggest we are much【M9】______ more likely to socialize with people from our own gender—75 per cent of best friends were with the same sex. Dr Tampubolon, who is based at the School of Social Sciences, said: " Friendship between women seems to be fundamentally similar to friendship【M10】______ between men."

Death comes quickly in the mountains. Each winter holiday makers are caught unawares as they happily ski away from the fixed runs, little realizing that a small avalanche can send them crashing in a bone-breaking fall down the slope and leave them buried under tons of crisp white snow. There are lots of theories about how to avoid disaster when hit by an avalanche. Practice is normally less cheerful.

The snow in the Salzburg of Austria where a recent disaster took place was typical avalanche material: For several days before the incident I had skied locally. Early winter snow was wearing thin and covered with ice. On top of that new, warmer flakes were gently falling to produce a dangerous carpet. To the skier who enjoys unmarked slopes it is tempting stuff, deep new power snow on a hard base--the skiing that dreams are made of And sometimes nightmares.

Snow falls in sections like a cake. Different sections have different densities because of the temperatures at the time of the fall and in the weeks afterwards. Problems come when any particular section is too thick and not sticking to the section beneath. The snow of the past few weeks had been falling in rather higher temperatures than those of December and early January. The result of these conditions is that even a slight increase in the temperatures sends a thin stream of water between the new snow and the old. Then the new snow simply slides off the mountain.

Such slides are not unexpected. Local citizens know the slopes which tend to avalanche and the weather in which such slides are likely. Traps are set to catch the snow or prevent it slipping; bombs are placed and exploded from time to time to set off small avalanches before a big one has time to build up; and above all, skiers are warned not to ski in danger areas.

In spite of this, avalanches happen in unexpected areas and, of course, skiers ignore the warnings. The one comfort to recreational skiers, however, is that avalanche incidents on the marked ski slopes are quite rare. No ski resort wants the image of being a death trap.

Each winter holiday makers in the mountains come face to face with death because ______.

A．they fail to realize how dangerous avalanches can be

B．they are not expert enough at skiing on the fixed runs

C．they are trying to avoid areas where avalanches happen

D．they ski great distances down the mountainsides

Mineral deficiencies can often be detected by specific symptoms such as chlorosis(loss of chlorophyll resulting in yellow or white leaf tissue), necrosis(isolated dead patches), anthocyanin formation(development of deep red pigmentation of leaves or stem), stunted growth, and development of woody tissue in an herbaceous plant. Soils are most commonly deficient in nitrogen and phosphorus. Nitrogen-deficient plants exhibit many of the symptoms just described. Leaves develop chlorosis; stems are short and slender; and anthocyanin discoloration occurs on stems, petioles, and lower leaf surfaces. Phosphorus-deficient plants are often stunted, with leaves turning a characteristic dark green, often with the accumulation of anthocyanin. Typically, older leaves are affected first as the phosphorus is mobilized to young growing tissue. Iron deficiency is characterized by chlorosis between veins in young leaves.

The word "exhibit" in the passage is closest in meaning to

A．fight off

B．show

C．cause

D．spread

A few common misconceptions: Beauty is only skin-deep. One's physical assets and liabilities don't count all that much in a managerial career. A woman should always try to look her best.

Over the last 30 years, social scientists have conducted more than 1,000 studies of how we react to beautiful and not-so-beautiful people. The virtually unanimous conclusion: Looks do matter, more than most of us realize. The data suggest, for example, that physically attractive individuals are more likely to be treated well by their parents, sought out as friends, and pursued romantically. With the possible exception of women seeking managerial jobs, they are also more likely to be hired, paid well, and promoted.

UN-American, you say, unfair and extremely unbelievable? Once again, the scientists have caught us mouthing pie-ties while acting just the contrary. Their typical experiment works something like this. They give each member of a group-college students, perhaps, or teachers or corporate personnel managers—a piece of paper relating an individual's accomplishments. Attached to the paper is a photograph. While the papers all say exactly the same thing the picture are different. Some show a strikingly attractive person, some an average-looking character, and some an unusually unattractive human being. Group members are asked to rate the individual on certain attributes, anything from personal warmth to the likelihood that he or she will be promoted.

Almost invariably, the better looking the person in the picture, the higher the person is rated. In the phrase, borrowed from Sappho, that the social scientists use to sum up the common perception, what is beautiful is good. In business, however, good looks cut both ways for women, and deeper than for men. A Utah State University professor, who is an authority on the impact of physical attractiveness on males is only modest. But its potential impact on females can be tremendous, making it easier, for example, for the more attractive to get jobs where they are in the public eye. On another note, though, there is enough literature now for us to conclude that attractive women who aspire to managerial position do not get on as well as women who may be less attractive.

According to the passage, people often wrongly believe that in pursuing a career as manager ________.

A．a person's property or debts do not matter much

B．a person's outward appearance is not a critical qualification

C．women should always dress fashionably

D．women should not only be attractive but also high-minded

Passage Two After years’ of being hung up because of the spendings far outweighing profits, deep sea mining is now emerging as a serious threat to the stability of ocean systems and processes that have yet to be understood well enough to punish in good conscience their large-scale destruction. Key to assessing what is at risk are technologies needed to access the deep sea. The mining company, Nautilus Minerals, has invested heavily in mining machinery. However, resources needed for independent scientific evaluation at those depths are essentially non-existent. The role of life in the deep sea relating to the carbon cycle is vaguely understood, and the influence of the microbial (微生物的) systems (only recently discovered) and the diverse ecosystems in the water column and sea bed have yet to be thoughtfully analyzed. The principle of exploiting minerals in the deep sea is based on their perceived current monetary value. The living systems that will be destroyed are perceived to have no monetary value. Will decisions about use of the natural world continue to be based on the financial advantage for a small number of people despite risks to systems that maintain planetary stability — systems that support human survival? The IUCN (International Union for Conservation of Nature) World Conservation Congress helps set in motion some significant and very timely actions that could help blunt the sharp edge of enthusiasm for dividing up the deep ocean. Whatever it takes, there must be ways to elevate recognition of the critical importance of intact natural systems. We need technologies to access the deep sea to independently explore and understand the nature of Earth’s largest living system. But most importantly, we need the will to challenge and change the attitudes, traditions and policies about the natural world that have driven us to burn through the assets as if there is no tomorrow. This “as if” can be a reality — or not — depending on what we do now. Or what we fail to do. However, there is undeniably cause for hope: there is still time to choose. 30. What is the author’s attitude toward deep sea mining?

A、Objective.

B、Pessimistic.

C、Suspicious.

D、Indifferent.
