The words can be used ONCE ONLY. 0 A. wider B. rapidly C. satisfactory D. bigger E. objects F. genuinely G. have H. arises I. possess
2、J. suddenly K. available L. property M. item N. cultivation O. upbringing The way that people spend their money, and the【 C1】 _ on which they spend it, are the last areas where free choice and individuality can be expressed. The choice reflects personal taste, the way people see themselves and the f
3、antasies they【 C2】_ about their lives, the restrictions on money【 C3】 _ to them, the presence of others in the family with a claim on that money, and the influence of current convention,【 C4】 _, surroundings and locality. Shopping is an important human activity. Yet shoppers are faced with a confusi
4、ng situation and a【 C5】 _ changing one. The confusion【 C6】 _ from the claims made by advertising, from inadequate information about new products, new materials, new places to shop a confusion enhanced by rising prices and a【 C7】 _ choice of goods than ever before. The search for the right purchase i
5、s based on ignorance of ones own needs and ignorance of the products fitness for those needs. When choosing any particular【 C8】 _, there are several lines of communication which might provide some guidance. Yet none of these is entirely【 C9】 _. For example, you can ask a shop assistant initially. Ev

They had neither the powerful teeth nor the strong claws of the big cats. They could not 【 C2】 _ with the bear, who
8、se strength, speed and claws provided an impressive “small-fire“ weaponry. They could not even defend themselves【 C3】 _ running swiftly like the horses, zebras or small animals. If the ape-men had attempted to compete on those terms in the open, they would have been doomed to【 C4】 _ and extinction.
9、But they were endowed with enormous concealed advantages of a kind not possessed by any of their competitors. In the search for the pickings of the forest, the ape-men had【 C5】 _efficient stereoscopic vision and a sense of colour that the animals of the grasslands did not possess. The ability to see
10、 clearly at close range permitted the ape-men to study practical problems in a way that lay far beyond the reach of the original inhabitants of the grassland. Good long-distance sight was【 C6】 _ another matter. Lack of long-distance vision had not been a problem for forest-dwelling apes and monkeys
11、because the higher the viewpoint, the greater the【 C7】 _ of sight so what they had had to do was climb a tree. Out in the open, however, this simple solution was not available. Climbing a hill would have helped, but in many places the ground was【 C8】 _. The ape-men adopted the only possible solution
12、. They reared up as high as possible on their hind limbs and began to walk upright. This vital change of physical position brought about considerable【 C9】 _. It was extremely unstable and it meant that the already slow ape-men became slower still. However, they persevered and their bone structure gr

14、entary J. distinguished K. flow L. refuting M. consisted of N. however O. dense The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and 【 C1】 _ it to the level of a
15、 free surface. A gas forms no free surface but tends to diffuse throughout the space available; it must【 C2】 _ be kept in a closed container, as in the case of a planets atmosphere. The distinction was a prominent feature of early theories【 C3】 _ the phases of matter. In the nineteenth century, for
16、example, one theory maintained that a liquid could be “dissolved“ in a【 C4】 _ without losing its identity, and another theory held that the two phases are【 C5】 _ different kinds of molecules. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in co
17、mmon. They are both forms of matter that have no permanent structure, and they both【 C6】 _ easily. They are fluids. The【 C7】 _similarity of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat. Suppose a closed container partially filled with a liquid is h
18、eated. The liquid expands, or in other words, becomes less【 C8】 _; some of it evaporates. In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and pressure at which the densities become【 C9】 _ is called the critica
19、l point. Above the critical point the liquid and the gas can no longer be【 C10】 _ ; there is a single, undifferentiated fluid phase of uniform density. 21 【 C1】 22 【 C2】 23 【 C3】 24 【 C4】 25 【 C5】 26 【 C6】 27 【 C7】 28 【 C8】 29 【 C9】 30 【 C10】 30 A. knowing B. source C. knowledge D. consult E. help F

21、 of habitual use, and a knowledge and understanding of the【 C2】_ subject-matter in his field of specialization. This is, as it were, his professional equipment. In addition to this, it is desirable that he should have a(n)【 C3】 _ mind, wide interests, a good memory and the ability to grasp quickly t
22、he basic principles of new developments. He should be willing to work on his own, often at high speeds, but should be humble enough to【 C4】 _ others should his own knowledge not always prove adequate to the task in hand. He should be able to type fairly quickly and accurately and, if he is working m
23、ainly for publication, should have more than a nodding【 C5】 _ with printing techniques and proof-reading. If he is working basically as an information translator, let us say, for an industrial firm, he should have the flexibility of mind to enable him to【 C6】 _ rapidly from one source language to an
