Scientists have confirmed that the majority of overweight people who try to lose weight either by cutting calories or exercising will return to their former size．Fewer than 10 percent of the l2 million British people who go on a diet each year succeed in losing significant amounts of weight and most of those who do put it all back on again within a year．

    The study of 25，000 people provides further evidence of the popularity of‘yo-yo dieting’where slimmers get into a cycle of losing weight and regaining it．The scientists，from the Medical Research Council’s National Survey of Health and Development，have concluded it is better to avoid getting fat in the first place．They followed 5，362 men and women from their birth in l946 and 20，000 from birth in l958，measuring their weight and blood pressure and assessing their lifestyles．The researchers found both groups began gaining weight in the 1980s and have steadily increased in size ever since．

    Dr Rebecca Hardy，the council’s programme leader on body size，said：“0nce people become, overweight，they continue extremely upwards．They hardly ever go back down．A(印刷不清两个单词)  weight but very few get back to normal。The best policy is to prevent people becoming overweight．For men weight goes up steadily through life。For women it starts slowly and accelerates in the mid-thirties．”

   But the study's findings do not mean dieting is pointless，as eating less and taking more exercise can increase fitness and lower blood pressure．In 2009，a quarter of adults and l4 percent of children were obese(过度肥胖的)，according to the Department of Health’s latest Health Survey for England．Although previous research has shown one in four Britons is trying to lose weight at any one time，it has been predicted that 60 percent of us will be obese by 2050，leading to even more cases of diabetes(糖尿病)，heart disease and cancer．Experts said we are programmed to put on weight rather than lose it．Dieting can make this tendency worse as decreasing calorie intake causes the body to go into starvation mode and reduce the amount of energy it naturally expends，making it even harder to lose weight．Commenting on the study，Professor Nick Finer from London Hospital，said：“It is unlikely that man would have progressed with mechanisms to fight against obesity which has only become a problem in the last 30～40 years．For most of human history，storing fat would have been an advantage．”

 47．According to Dr Rebecca Hardy，which of the following is TRUE?

    A．It is easier for men to lose weight than women．

    B．Once people lose weight，they never put on weight again．

    C．Never to become fat is the best way of keeping a good shape．

    A．decreasing calorie intake makes it even harder to lose weight

    B．the idea that people lose weight with mechanisms is practical

    C．being overweight is a lasting problem through the human history

As we know, it is very important that a firm should pay attention to the training of its staff as there exist many weak points in its various departments. Staff training must have a purpose, which is defined when a firm considers its training needs, which are in turn based on job descriptions and job specifications(规范).

   A job description should give details of the performance that is required for a particular job, and a job specification should give information about the behaviour, knowledge and skills that are expected of an employee who works in the position. When all of this has been collected, it is possible to make a training specification. This specifies(详细说明) that the training department must teach for the successful performance of the job, and also the best methods to use in the training period.

   There are many different training methods, and there are advantages and disadvantages in all of them. Successful training performances depend on an understanding of the difference between learning about skills and training in using them. It is frequently said that learning about skills takes place “off the job” in classroom, but training in using these skills takes place “on the job,” by means of such activities as practice in the workshop.

   It’s always difficult to evaluate the costs of a training programme. The success of such a programme depends not only on the methods used but also on the quality of the staff who do the training. A company can often check savings in time and cost by examining the work performed by the workers and technicians who have completed a training programme. The evaluation of management training is much more complex than that.

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.

1.We should take good care of our eyes________.     .

2.When things far away seem indistinct(模糊不清) , one is probably________.     .

3.The underlined word blurry in the second paragraph probably means_______.

4.Having two eyes instead of one is particularly useful for_______   

We are all interested in equality, but while some people try to protect the school and examination system in the name of equality, others, still in the name of equality, want only to destroy it.

Any society which is interested in equality of opportunity and standards of achievement must __1  test its pupils. The standards may be changed — no examination is 2  — but to have no tests or examinations would mean the end of equality and of standards. There are groups of people who oppose this view and who do not 3 either in examinations or in any controls in school or on teachers. This would mean everything would depend on 4  since every pupil would depend on efficiency, the values and the purpose of each 5  .

Without examinations, employers will look for employees from the 6  respected schools and from families known to them – a form of favoritism will replace equality. At the moment, the bright child from an ill-respected school can show certificates to prove he is _7  for a job, while the lack of a certificate indicates the unsuitability of a 8  child attending a well-respected school. This defense of excellence and opportunity would disappear if examinations were 9  , and the bright child from a poor family would be a prisoner of his or her school’s reputation, unable to 10 for employment with the child from the 11__ school.

The opponents of the examination system suggest that examinations are an 12  force because they show differences between pupils. According to these people, there must be no special, __13 or academic class. They have even suggested that there should be no form of difference in sport or any other area: all jobs or posts should be filled by unsystematic 14  . The selection would be made by people who themselves are 15  selected by some computer.
