【文章內(nèi)容簡(jiǎn)介】 ober 31st. There are many customs associated with Halloween. One of these is the game of ‘ trick or treat’. Children, dressed up as witches, ghosts or monsters, knock on their neighbours’ doors, and shout ‘trick or treat!’ If they are lucky, they receive a ‘treat’ – a bar of chocolate, or some sweets or some money. If, however, their neighbours refuse to give them anything, they play a trick on them. They might spray their front door with shaving foam(剃須膏 ), or knock on their doors and then run away! Another game played at Halloween is ‘bobbing for apples’. In this game, a bowl is filled with water, and apples are placed in it. Children then have to take a bite from one of the apples without using their hands. This game is difficult and messy(雜亂的 ), but great fun! 60. Bonfire Night and Halloween _________.

Some experts believe that the answer is to make jobs more varied. Do more varied jobs lead to greater productivity? There is something to suggest that while variety certainly makes the worker39。s life more enjoyable, it does not make him work harder. So variety is not important. Other experts feel that giving the worker freedom to do his job in his own way is important and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its plicated machinery which must be used in a fixed way. Thus while freedom of choice may be important, there is very little that can be done to achieve this. Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are said to be experimenting with having many small production lines rather than a large one, so that each worker contributes more to the production of the cars on his line. It would seem then that the degree of worker contribution is important. To what extent does more money lead to greater productivity? The workers themselves certainly think this is important, but perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if panies succeed in making workers39。 jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them. 65. Which of the following things will not increase productivity? A. Making jobs more varied. B. Giving workers the freedom to do his jobs in their own way. C. Increasing the workers39。 contribution to production. D. Longer working hours. 66. The last sentence in this passage means that if panies manage to make workers39。 jobs more interesting, _________. A. they will want more money B. they will demand shorter working hours C. more money and shorter working hours are important D. more money and shorter working hours will not be so important to them 67. In this passage, the writer tells us _________. A. how to make the workers more productive B. possible factors leading to greater productivity C. more money leads to greater productivity D. how to make workers39。 jobs more interesting 68. The writer of this passage is probably a _____________. A. teacher B. worker C. manager D. physicist D Zinc(鋅 ) is one of about 20 elements necessary for good health. It is present in the body in a very small amount, but it makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other element work. Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys, formerly with the United States Air Force, noted that the laboratory animals recovered faster when some substances were added to their food. One of these substances was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate (硫酸鹽 ) recovered in one half the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by a lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate. The amount of zinc in the body can be found by examining the blood and hair. A lack of this important element is not unmon among people in both industrial and developing countries. Zinc is found in most high protein foods, such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these foods. Food makers
