1、【题目】翻译:

如今,中国正步入老龄化社会,因此独生子女一代面临着巨大的工作和生活压力。中国政府开始适当调整计划生育政策,允许一些家庭在特殊情况下生育二胎。但调查显示,很多夫妻迫于不断加重的经济压力,放弃生育二胎。因此,要从根本上解决老龄化的问题不能依靠出生率的上升,最有效的办法是建立有效的社会保障制度。

答案:

Nowadays, China is stepping into the aging society. Therefore, the only-child generation is facing enormous pressure both from work and life. The Chinese government has begun to adjust the familyplanning policy and allows some families to have a second child under certain circumstances. However, the survey shows thatsome couples abandon to have a second child due to the increasing financial burden. Thus, in order to solve the aging problem,the basic thing is not relying on the increase of birth rate. The best solution is to establish an effective social security system.

1、【题目】Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the languages he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people. In the same way, when children learn to do all the other things they learn to do without being taught-to walk, run, climb, whistle, ride a bicycle-compare those performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his own mistakes for himself, let alone correct them. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he becomes dependent on the teacher. Let him do it himself. Let him work out, with the help of other children if he wants it, what this word says, what answer is to that problem, whether this is a good way of saying or doing this or not.

If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let’s end this nonsense of grades, exams, marks, Let us throw them all out, and let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what they know or do not know.

Let them get on with this job in the way that seems sensible to them. With our help as school teachers if they ask for it. The idea that there is a body of knowledge to be learnt at school and used for the rest of one’s life is nonsense in a world as complicated and rapidly changing as ours. Anxious parents and teachers say, “But suppose they fail to learn something essential they will need to get in the world?” Don’t worry! If it is essential, they will go out into the world and learn it.

1.What does the author think is the best way for children to learn things?

A.by copying what other people do.

B.by making mistakes and having them corrected.

C.by listening to explanations from skilled people.

D.by asking a great many questions.

2.What does the author think teachers do which they should not do?

A.They give children correct answers.

B.They point out children’s mistakes to them.

C.They allow children to mark their own work.

D.They encourage children to mark to copy from one another.

3.The passage suggests that learning to speak and learning to ride a bicycle are___.

A.not really important skills.

B.more important than other skills.

C.basically different from learning adult skills.

D.basically the same as learning other skills.

4.Exams, grades, and marks should be abolished because children’s progress should only be estimated by___.

A.educated persons.

B.the children themselves.

C.teachers.

D.parents.

5.The author fears that children will grow up into adults while being___.

A.too independent of others.

B.too critical of themselves.

1、【题目】PartVWriting

写作指导

这是一篇描写文(Description)。用通俗的话说,描写文就是用文字给人物、地点、景物画象。一篇描写文主要是通过所感受的细节——所见所闻发展而来的。在写人时,不仅仅要用细节描写其外貌,而要注重通过他的言行来表现其人物性格、思想和品德,更要抓住他区别于他人的性格特点,这样就容易给读者留下深刻的印象。短文的第一、二段叙述故事发生的时间、地点,故事发生的原因及故事所涉及的人物。文章的三、四、五段描写的是人物的外貌,穿着及性格特点。通过对人物言行的简单描写来揭示主人翁的助人为乐的高尚精神。短文的最后一段,要用一句话概括作者对主人翁的看法:Agoodguy。文章有描述,有议论,要加叙加议,有血有肉,上下文连贯要紧密,首尾要呼应,人和事要给人们留下深刻印象。

Sample Writing

The First Impression of My Roommate

It was my first day at the institute. I got into the building where I was going to live, and looked door after door for my name. At last I found it. In the room, there was already a student making his bed. After we said “how do you do?” to each other, he continued his work, paying no more attention to me. I looked around the room and found that it had been thoroughly cleaned. No doubt it was he who had done it.I looked at him. He was thin, short and dark. His hair was like a bundle of straw. His dirty clothes and tired look told me that he had had a long journey. His clothes were made of cheap cloth, and he wore a pair of rubber shoes, which were very unfashionable. He was not a very smart freshmen at all.

The second time he spoke, his accent told me that he was from the south. “Shall I help you to get your luggage from the office?”

I did not refuse since I really needed help. He was quick in movement. He walked out of the room and was soon far ahead of me to the office.

“A good guy,”I said to myself.“I will make friends with him ”,and I hurried and caught up with him.

1、【题目】Recent research has claimed that an excess of positive ions in the air can have an ill effect on people’s physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm, earthquakes when winds such as the Mistral, Hamsin or Sharav are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibres, or from TV sets, duplicators or computer display screens.

When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some sensitive people suffer nausea or even mental disturbance. Animals are also affected, particularly before earthquakes, snakes have been observed to come out of hibernation, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California.

Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls.

To increase the supply of negative ions indoors, some scientists recommend the use of ionisers: small portable machines, which generate negative ions. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.

1.What effect does exceeding positive ionization have on some people?

A.They think they are insane.

B.They feel rather bad-tempered and short-fussed.

C.They become violently sick.

D.They are too tired to do anything.

2.In accordance with the passage, static electricity can be caused by___.

A.using home-made electrical goods.

B.wearing clothes made of natural materials.

C.walking on artificial floor coverings.

D.copying TV programs on a computer.

3.A high negative ion count is likely to be found___.

A.near a pound with a water pump.

B.close to a slow-flowing river.

C.high in some barren mountains.

D.by a rotating water sprinkler.

4.What kind of machine can generate negative ions indoors?

A.Ionisers.

B.Air-conditioners.

C.Exhaust-fans

D.Vacuum pumps.

5.Some scientists believe that___.

A.watching animals to anticipate earthquakes is more effective than depending on seismography.

B.the unusual behavior of animals cannot be trusted.

C.neither watching nor using seismographs is reliable.

D.earthquake

1、【题目】翻译训练:普通话与方言

中国土地广阔,人口众多。尽管全国都讲汉语,但是不同地区的人说汉语的方式不同,这被称为方言。方言一般被称为地方话,是汉语在不同地区的分支,只在特定地区使用。汉语方言非常复杂。它们有以下三方面不同:发音、词汇和语法。发音的区别最为显著。2000多年前,中国人发现社交时应该使用统一的语言。和方言相比,普通话(mandarin)能被所有人理解。普通话有利于不同种族、地区人民之间的信息传递和文化交流。

答案:

China has a vast land and a large population. Even though the Chinese language is spoken all over the country, people in different areas speak it in different ways, which are called dialects. Generally called local languages, dialects are branches of the Chinese language in different regions, and are only used in certain areas. Dialects of the Chinese language are very complicated. They differ from each other in three aspects: pronunciation ,vocabulary and grammar. And the difference in pronunciation is the most outstanding. Over2,000 years ago, Chinese people realized that a common language should be used in social activities. Compared with dialects,mandarin can be understood by all people. It is beneficial to information transmission and cultural exchange between ethnic groups and people indifferent places..

解析:

1.土地广阔:可转译为名词短语avastland。vast是指“幅员辽阔的”,这里不能用wide。但是表示物体的宽度时可以用wide,比如:Theriveris100mwide.(这条河宽100米。)

2.人口众多:即“很多的人口”,可转译为名词短语alargepopulation。

3.与...不同:可译为differfrom或bedifferentfrom。

4.发音的区别最为显著:可译为Thedifferenceinpronunciationisthemostoutstanding。

5.有利于:可译为bebeneficialto。

6.信息传递和文化交流:可译为informationtransmissionandculturalexcha

1、【题目】Passage 2

Questions 6 to 10 are based on the following passage:

When aluminum was first produced about a hundred and fifty years ago, it was so difficult to separate form the ores in which it was found that its price was higher than that of gold. The price remained high until a new process was discovered for refining the metal with the aid of electricity approximately three quarters of a century later. The new method was so much cheaper that aluminum because practical for many purposes, one of which was making pots and pans.

Aluminum is lightweight, rustproof and easily shaped into different forms. By mixing it with other metals, scientists have been able to produce a variety of alloys, some of which have the strength of steel but weigh only one third as much.

Today, the uses of aluminum are innumerable. Perhaps its most important use is in transportation. Aluminum is found in the engine of automobiles, in the hulls of boats. It is also used in many parts of airplanes. In fact, the huge “airbus” planes would probably never have been produced if aluminum did not exist. By making vehicles lighter in weight aluminum has greatly reduced the amount of fuel needed to move them, Aluminum is also being used extensively in the building industry in some countries.

Since aluminum is such a versatile (多用的) metal, it is fortunate that bauxite (铝土矿), which is one of its chief sources, is also one of the earth’s most plentiful substances. As the source of aluminum is almost inexhaustible, we can expect that more and more uses will be found for this versatile metal.

6. The price of aluminum was sharply reduced when people discovered a new refining process with the aid of .

A. wind B. solar energy C. hydraulic power D. electricity

7. Aluminum is .

A. lightweight, rustproof but not easily shaped into different forms

B. heavyweight, rustproof and easily shaped into different forms

C. lightweight, rustproof and easily shaped into different forms

D. lightweight and easily shaped into different forms but it is easy to become rusty

8. Which of the following is NOT true?

A. Aluminum is widely used in transportation.

B. Aluminum is also used in many parts of airplanes.

C. Aluminum is being used extensively in the building industry.

D. Aluminum is not used in its pure form.

9. Aluminum is found on earth mostly in the form of .

A. pure metal B. bauxite C. gold D. liquid

10. What is the passage talking about?

A. The features of aluminum and its functions. B. The process of aluminum.

C. The discovery of aluminum. D. The promising future of aluminum.
