But they could not provide effective medical care to their patients without the help of numerous other medical workers. Fr

8、om the angle of the patients, the nursing staff is particularly important. Nurses are usually in close contact with patients as long as they are in the hospital. A nurse does not study for as many years as a doctor. However, each must be equally trained. Caring for sick persons requires a great deal

9、 of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night. The nursing staff in a hospital is usually quite large and various. Nursing services, after all, must be provided on a 24-hour basis. There are professional (专业的) nurses, practical nurses

10、, nurses aids, and orderlies (勤杂工). The general term nurse refers to a person trained to offer bedside care to sick persons. Under the supervision (管理) of the head nurse, the nursing staff in a hospital ward must attend to patients needs. This responsibility continues around the clock, and so nurses

11、 must work in shifts. A shift is a period of duty, usually eight hours in length. The nurses on the ward rotate (轮换) their shifts. Some take turns working night duty; others work odd shifts. All of them work out of a central area on the ward called the nurses station. A nurse must always be on her g

12、uard. She can never afford to be careless. This is true in all nursing situations , but it is especially true in the intensive care unit. Patients under intensive care are critically ill, and they must be monitored at all times. The nurses who do intensive care duty have one of the most demanding jo

16、.RightB.WrongC.Not mentionedPeople, Customs and Habits 1. Every ten years the United States makes a complete count, or census, of its people. When the first count was made in 1790, the new nation had fewer than 4 million people, almost all living along the East Coast. Today, there are more than 226

17、million. 2. We moved slowly through the city and entered a slum district. The streets crowded with people. People eating, people washing, people sleeping. People visiting each other, arguing and screaming. People pushing their hands through the taxi windows begging. People holding on to the sides of

18、 buses. People, people, people, people. 3. We have the ability to keep what we have learned in our minds so that we can call it up again for use later on. What we remember in this way may be words, figures, dates, poetry, events in our own lives and things like arithmetic or historic facts, and even

19、 skilled actions such as playing the piano or riding a bicycle. 4. Different countries and different races have different manners. Before entering a house in some Asian countries, it is good manners to take off your shoes. In European countries, even though shoes sometimes become very muddy, this is

20、 not done. A guest in a Chinese house never finishes a drink. He leaves a little, to show that he has had enough. In England, a guest always finishes a drink to show that he has enjoyed it. 5. Many visitors find the fast pace at which Americans move very troubling. They always appear to be hurrying

23、hy of Hormones All of the cells in a particular plant start out with the same complement of genes. How then can these cells differentiate and from structures as different as roots, stems, leaves, and fruits? The answer is that only a small subset of the genes in a particular kind of cell are express

24、ed, or turned on, at a given time. This is accomplished by a complex system of chemical messengers that in plants include hormones and other regulatory molecules. Five major hormones have been identified; auxin (生长素), abscisic acid(脱落酸) ,cytokinin(细胞激动素), hetylene(乙烯), and gibberellin(赤霉素). Studies

25、of plants have now identified a new class of regulatory molecules called oligosaccharins. Unlike the oligosaccharins, the five well-known plant hormones are pleiotropic (多向性的) rather than specific, that is, each has more than one effect on the growth and development of plants. The five have so many

26、simultaneous effects that they are not very useful in artificially controlling the growth of crops. Auxin, for instance, stimulates the rate of cell elongation(拉长), causes shoots to grow up and roots to grow down, and inhibits the growth of lateral(侧面的) shoots. Auxin also causes the plant to develop

27、 a vascular(维管的) system, to from lateral roots, and to produce ethylene. The pleiotropy of the five well-studied plant hormones is somewhat analogous (类似的) to that of certain hormones in animal. For example, hormones from the hypothalamus (下五脑) in the brain stimulate the anterior(前面的) lobe of the pi

28、tuitary gland to synthesize and release many different hormones, one of which stimulates the release of hormones from the adrenal(肾上腺的) cortex(皮质|). These hormones have specific effects on target organs all over the body. One hormone stimulates the thyroid (甲状腺的) gland, for example, another the ovar

29、ian (子房)follicle cells, and so forth. In other words, there is a hierarchy(统治集团) of hormones. Such a hierarchy may also exist in plants. Oligosaccharins are fragments of the cell wall released by enzymes (酶): different enzymes release different oligosaccharins. There are indications that pleiotropic

30、 plant hormones may actually function by activating the enzymes that release these other, more specific chemical messengers from the cell wall. （分数：-1.00）(1).According to the passage, the five well-known plant hormones are not useful in controlling the growth of crops because_.（分数：-0.20）A.it is not

31、known exactly what functions the hormones performB.each hormone has various effects on plantsC.none of the hormones can function without the othersD.each hormone has different effects on different kinds of plants(2).The passage suggests that which of the following is a function likely to be performe

32、d by an oligosacharin?（分数：-0.20）A.To stimulate a particular plant cell to become part of a plants root system.B.To activate enzymes that release specific chemical messengers from plant call walls.C.To duplicate the gene complement in a particular plant cell.D.To produce multiple effects on a particu

33、lar subsystem of plant cells.(3).The author mentions specific effects that auxin has on plant development in order to illustrate the_（分数：-0.20）A.way in which hormones are produced by plantB.hierarchical nature of the functioning of plant hormones.C.differences between the best-known plant hormones.D

34、.concept of pleiotropy as it is exhibited by plant hormones.(4).According to the passage, which of the following best describes a function performed by oligosacchains?（分数：-0.20）A.Interacting with one another to produce different chemicals.B.Pleasing specific chemical messengers from a plants cell wa

35、lls.C.Reoducing the hormones that cause plant cells to differentiate to perform different functions.D.Influencing the development of a plants cells by controlling the expression of the cells genes.(5).The passage suggests that, unlike the pleiotropio hormones, oligosaccharins could be used effective

36、ly to_.（分数：-0.20）A.trace the passage of chemicals through the walls of cells.B.pinpoint functions of other plant hormones.C.artificially control specific aspects of the development of crops.D.alter the complement of genes in the cells of plants.Adaptation of Living Things Certain animals and plants

37、develop characteristics that help them cope with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and

38、in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their environments. Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A plant, for example, depends upon

39、 its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the suns energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of p

40、lants have. Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still

41、 when an enemy is near. Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its won environment, as do warm-blooded mammals, which have the abili

42、ty to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions

43、. （分数：-1.00）(1).Some plants and animals develop superior characteristics so that they may_.（分数：-0.20）A.help others of their kind get food, shelter and other things needed.B.survive even in extremely severe conditionsC.become better adapted to the environments than others of their kind.D.result in th

44、e evolution and production of more intelligent organisms.(2).In the first paragraph, the word “environments“ could best be replaced by_.（分数：-0.20）A.contextsB.surroundingsC.neighborsD.enemies(3).It can be inferred from this passage that the feathers of a bird care colored_.（分数：-0.20）A.to frightened i

45、ts enemies.B.to attract its enemiesC.to adjust its body heatD.to match its environment(4).Which of the following is not directly mentioned?（分数：-0.20）A.A living thing may adapt in its structure.B.An organism may adapt in its function.C.A living creature may adapt in its genetic makeup.D.A living orga

46、nism may adapt in its sleeping habit.(5).The author cites the behavior of warm-blooded mammals in order to illustrate which of the following?（分数：-0.20）A.A living thing may have the ability to create an environment of its ownB.A living creature may have the ability to remain still when an enemy is ne

47、ar.C.A living creature may have the ability to make food from its inorganic chemicalsD.A living creature may have the ability to change the color of its skin.Memory Class Stan Field knows what age can do to a persons memory, and hes not taking any chances with his. He chooses his food carefully and

48、gets plenty of exercise. He also avoids stress, coca cola and cigarette smoke. Whats more, at breakfast each morning, the 69-year-old chemical engineer swallows a plateful of pills in the hope of boosting his brain power. Michelle Amove is less than half Fields age, but no less concerned about her m

49、emory. While working round the clock to finish a degree in film studies, the 33-year-old New Yorker had the alarming sensation that she had stopped retaining anything. “I couldnt even remember names,“ she says. “I thought, Oh, no, Im over 30. Its all downhill from here. “ Besides loading up on supplements, Amove signed up for a memory enhancing course at New Yorks Mount Siani Medical Center. And when she got there, she found herself surrounded by people who were just as worried as she was. For millions of Amer
