The exact nature of this cycle varies from person to person, and 3do our preferences for activity versus rest. Our natural rhythms are 4 by internal drives and external stimulation. Typica
28、lly, external stimulation wins out over what our internal guide tells us. For example, when we fly across six time zones, we have to fit into a different time frame whether we like it or not. The same is true when we work the night shift. These are 5examples of what most of us experience every day o

One is the need for predictability and standardization in the workplace, especially in companies that do business around the

32、1，分数：30.00)29.PART V READING COMPREHENSION_30.SECTION AIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer._(l)Naturally, in a group of animals
33、 as diverse as the snakes, and with so many varied enemies, there are numerous defensive reactions and devices. There is, however, one general pattern of behavior. In the presence of suspected enemy the first reaction is to try to escape observation; if this fails, the next resort is the flight to s
34、ome inaccessible retreat, but if this is not possible, or is circumvented, various kinds of intimidatory gestures and warning devices are brought into play; in the last resort the snake attacks. This pattern varies with the circumstances; some stages may be omitted or combined unpredictably whilst;
35、some notoriously irascible species may dispense with all the preliminaries and attack almost at once, though seldom or never without some provocation. (2)Amongst the factors that increase aggressiveness are hunger, the mating season and surprise, with the last mentioned the commonest; when hunting f
36、or food or for mate, activity and the aggressive instinct are both at their peak. Owing to their poor sense of hearing snakes are very liable to be, quite literally, caught napping and a similar situation arises during their periods of temporary blindness just before sloughing (蜕皮) begins. By far th
37、e greatest number of snake-bit accidents result from the unwitting disturbance of resting snakes, and this hazard is much increased with species that are well disguised and whose natural instinct is to trust to this concealment as their principal defense. As well as differences in aggressiveness bet
38、ween individuals of the same species according to the circumstances and conditions, there are also notable differences between species, even closely allied species; and the reports of those who have been attacked may understandably be lacking in objectivity. So it is impossible to forecast, even in
39、outline, how any encounter will develop. (3)The Hamadryad, for example, is usually credited with being amongst the most aggressive of snakes, and there are many accounts of unprovoked attacks, yet on one occasion fourteen men and seven dogs passed and returned within two yards from a nest and no sna
40、ke was seen although the female, which guards the nest, could not have been far away.（分数：4.00）(1).It is difficult to predict what would happen when a snake meets a man because _.（分数：2.00）A.no one has ever clearly known how he himself was bitB.man tends to be subjective when he describes his encounte

42、akes are more aggressive and more ready to attackC.it is hard to forecast whether and how snakes would attackD.snakes often conceal themselves as their principal defense(l)In such a changing, complex society formerly simple solutions to informational needs become complicated. Many of lifes problems
43、which were solved by asking family members, friends or colleagues are beyond the capability of the extended family to resolve. Where to turn for expert information and how to determine which expert advice to accept are questions facing many people today. (2)In addition to this, there is the growing
44、mobility of people since World War II. As families move away from their stable community, their friends of many years, their extended family relationships, the informal flow of information is cut off, and with it the confidence that information will be available when needed and will be trustworthy and reliabl
