参考译文

肥胖人士要减肥的话，必须要密切关注自己的饮食。最好的方法就是开始一项体重控制计划。首先，与你的医生讨论这个问题，这是明智之举。他可以建议每天你应该食用的卡路里的数量，他可以告诉你在节食的时候要注意运动。一个很好的方法就是慢慢地减肥，一次减少一两磅就很多了。

用你熟悉的食物计划你的三餐。这就意味着，你的节食计划里应该包括那些你习惯了的、成为你通常饮食习惯一部分的食物。当你达到你希望的重量时，可以将一些简单的食物添加到你的饮食中，以便你能保持你想要的体重。当你节食的时候，试着养成一个以后你还能保持的饮食习惯，从而可以维持你的理想体重。

节食时，要食用低卡路里的食物，不要吃如肥肉、油炸食品、糖果、蛋糕、奶油和软饮料之类的东西。试着喝不带糖和奶油的咖啡或茶。小点心可以是你食谱的一部分。例如，可以在正餐之间吃一片水果或者一份饭后剩下的简单的甜点。

保持忙碌!这样的话你将可以脱离你的食物。充分利用各种锻炼的机会，只要有可能，就要尽量走路而不是开车。节食愉快!

Early or Later Day Care

The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion.

Firstly, anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone - far from it. Secondly, common sense tells us that day care would not be so widespread today if parents, care-takers found children had problems with it. Statistical studies of this kind have not yet been carried out, and they have uniformly reported that day care had a neutral or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.

But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.

C) The first three years of one's life is extremely important to the later development of personality.

D) Children under three get used to the life at nursery schools more readily than children over three.

Keys：CAADC

In what now seems like the prehistoric times of computer history, the early postwar era, there was a quite widespread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction.

Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone awry. Questioning and routine double checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the following warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.

1.What is the main purpose of this passage?

A. To look back to the early days of computers.

B. To explain what technical problems may occur with computers.

C. To discourage unnecessary investment in computers.

D. To warn against a mentally lazy attitude towards computers.

2.According to the passage, initial concerns about computers were that they might_____

A. lead us into the post-war era

B. be quite widespread

C. take control

D. take over routine tasks

3.The passage recommends those dealing with computers to_____

A. be reasonably skeptical abort them

B. check all their answers

C. substitute them for basic thinking

D. use them for business purposes only

4.An "internal computer" is_____

A. a computer uses exclusively by one company for its own problems

B. a person's store of knowledge and the ability to process it

C. the most up-to-date in-house computer a company can buy

D. a computer from the post-war era which is very reliable

5.The passage suggests that the present-day problem with regard to computers is_____

A. challenging

B. psychological

C. dramatic

D. malfunctioning

[难点]

1.widespread 普遍的，广泛的

2.relieve 减轻，解除，使得到解脱

3.dramatic 引人注目的，突然的

4.foreseen 预见的，预知的

5.reluctant 不情愿的，不愿意的

6.authority 权威

7.malfunction 发生故障，发生功能障碍

8.invest 投资;花钱买;耗费，投入

9.rely on 依赖，依靠

10.go awry 出岔子，失败;(人)背离正道

11.substitute 代替物，代用器

[答案]

1.D

考点：这是一道典型的文章主旨题。

解析：文章分析了人们过分依赖电子计算机这一问题，在结尾向人们提出了忠告：尽管电子计算机可以提供各种帮助，但是它不应被视为代替人们基本思维和推理的东西。文章主要目的是警告人们在心理上对计算机不要采取懒惰的态度。

2.C

考点：这是一道细节题。

解析：问题的答案在文章的第一句之中："In what now seems like the prehistoric times of computer history, the early postwar era, there was a quite widespread concern that computers would take over the world from man one day."(在计算机历史的前期即战后初期，人们普遍担心计算机可以能会代替人类统治世界)选项C与这一句的含义完全一致，故为正确答案。

3.A

考点：这是一道推断题。

解析：文章第二段第二句说："Questioning and routine double checks must continue to be as much a part of good business as they were in pre-computer days."由此我们可以推断出，文章建议那些与计算机打交道的人应该对它们采取合理的怀疑态度。

4.B

考点：这是一道理解题

解析：理解："internal computer"的含义的关键是确定"internal"的意思。这个词几个基本含义：内部的，体内的，内在的。从它所在的上下文来看，它的意思是："体内的"。"internal computer"是一种比喻说法，指人的大脑，它比计算机更聪明、更复杂，具有储存知识和运用知识的能力。因此，选项B是正确答案。

5.B

考点：这是一道推断题。

解析：根据文章内容我们得知，当今电子计算机的问题既不是令人深思的也不是容易出故障。而选项C与文章内容不符。它的问题是人们在心理上过分信赖它，对它的能力毫不怀疑。

You might think that good-looking men have every advantage in life.

But new study suggests being handsome may not always work in a man' s favour—at least when it comes to his career.

The research claims that attractive men are less likely to be given a job in a competitive work- place because they intimidate bosses. "It' s not always an advantage to be pretty," says Marko Pite- sa, an assistant professor at the University of Maryland. "It can backfire if you are perceived as a threat. "

Interestingly, in Pitesa' s study, it was male attractiveness in particular, rather than female beauty, that made the most difference. If the interviewer expected to work with the candidate as part of a team, then he preferred goodlooking men. However, if the interviewer saw the candidate as a potential competitor, the interviewer discriminated in favour of unattractive men.

"l——he results suggest that interviewers were not blinded by beauty, and instead calculated which candidate would further their own career.

"The dominant theoretical perspective in the social sciences for several decades has been that biases and discrimination are caused by irrational prejudice," Pitesa says.

"The way we explain it here, pretty men just seem more competent, so it is actually subjec- tively rational to discriminate for or against them. "

On a deeper level, she adds, the behaviour remains irrational, since there' s no evidence that a real link exists between looks and comoetence.

57.范文

There might be a common view that good—looking people can take ad- vantages of their superior appearances in the daily life，especially for the preRy men in the job hunting market.However，according to a new research，good appearance is no longer been the silver bullet in a job inter-view.

The results showed that although there Was still a preference to cooperate with the attractive man and compete against the unattractive mall，and did not mind to work with them.However，people were not likely to pick a goodlooking man as their potential competitors.

In my opinion，we should not depend ourselves on our appearance in terms of job hunting.

Good appearance may bring US some benefits，but what is highly valued in the job market is our talents and abilities.
