【2016·上海】Reading Comprehension
Section A
Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.
In the 1960s, Douglas McGregor, one of the key thinkers in the art of management, developed the mow famous Theory X and Theory Y. Theory X is the idea that people instinctively 51 work and will do anything to avoid it. Theory Y is the view that everyone has the potential to find satisfaction in work.
In any case, despite so much evidence to the 52 , many managers still agree to Theory X. They believe, 53 , that their employees need constant supervision if they are to work effectively, or that decisions must be imposed from 54 without consultation. This, of course, makes for authoritarian (专制的) managers.
Different cultures have different ways of 55 people. Unlike authoritarian management, some cultures, particularly in Asia, are well known for the consultative nature of decision-making—all members of the department or work group are asked to 56 to this process. This is management by the collective opinion. Many western companies have tried to imitate such Asian ways of doing things, which are based on general 57 . Some experts say that women will become more effective managers than men because they have the power to reach common goals in a way that traditional 58 managers cannot.
A recent trend has been to encourage employees to use their own initiative, to make decisions on their own without 59 managers first. This empowerment(授权) has been part of the trend towards downsizing: 60 the number of management layers in companies. After de-layering in this way, a company may be 61 with just a top level of senior managers, front-line managers and employees with direct contact with the public. Empowerment takes the idea of delegation (委托) much further than has 62
been the case. Empowerment and delegation mean new forms of management control to 63 that the overall business plan is being followed, and that operations become more profitable under the new organization, rather than less.
Another trend is off-site or 64 management, where teams of people linked by e-mail and the Internet work on projects from their own houses. Project managers evaluate the 65 of the team members in terms of what they produce for projects, rather than the amount of time they spend on them.
51. A. desire B. seek C. lose D. dislike
52. A. contrary B. expectation C. degree D. extreme
53. A. vice versa B. for example C. however D. otherwise
54. A. outside B. inside C. below D. above
55. A. replacing B. assessing C. managing D. encouraging
56. A. refer B. contribute C. object D. apply
57. A. agreement B. practice C. election D. impression
58. A. bossy B. experienced C. western D. male
59. A. asking B. training C. warning D. firing
60. A. doubling B. maintaining C. reducing D. estimating
61. A. honored B. left C. crowded D. compared
62. A. economically B. traditionally C. inadequately D. occasionally
63. A. deny B. admit C. assume D. ensure
64. A. virtual B. ineffective C. day-to-day D. on-the-scene
65. A. opinion B. risk C. performance D. attractiveness
【文章大意】本文是说明文，作者在第一段中提出道格拉斯·麦克雷戈所提出的人性假设理论中的X 理论和Y理论，并介绍了现代社会中一种新型管理理论：授权管理及其作用。
51.D 考查上下文串联。
根据后半句…will do anything to avoid it可知很多人为了避免工作而愿意做任
何事情，说明那些人大多数人生性都是懒惰的，都不愿意工作，他们尽可能地逃避工作。
故D 项正确。
52.A 考查上下文串联。
短语to the contrary相反的；to the degree在某种程度上；to the extreme走向
极端；在文章第一段中提到了X理论，大多数人都缺乏进取心和责任心，不愿对人和事负责，
没有什么雄心壮志，不喜欢负责任，宁可被领导。
而Y理论认为大多数人愿意对工作、对他人。

At present, these technologies are still expensive, though.Researchers from Georgia Tech say that they have come up with a low-cost device(装置)that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏)with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by extension, whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right.It also doesn't require a new type of technology that people aren't already familiar with. Everybody uses a keyboard and everybody types differently.In a study describing the technology, the researchers had 100 volunteers type the word “touch”four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.28. Why do the researchers develop the smart keyboard?A. To reduce pressure on keys.B. To improve accuracy in typingC. To replace the password system.D. To cut the cost of e-space protection.29. What makes the invention of the smart keyboard possible？A. Computers are much easier to operate.B.
