1、Pronouncing a LanguagePronouncing a language is a skill. Every normal person is an expert in the skill of pronouncing his own language; but few people are even fairly proficient at pronouncing foreign languages. Now there are many reasons for this, some obvious, some perhaps not so obvious. But I suggest that the basic reason why people in general do not speak foreign languages very much better than they do native language is that they fail to understand the true nature of the problem of learning to pronounce. Far too many people fail to realize that pronouncing a foreign language is a skill----one that needs careful training of a special kind, and one that cannot be gained by just leaving it to take care of itself. I think even teachers of language, while realizing the importance of a good accent, often neglect, in their practical teaching, the branch of study concerned with speaking the language. So the first point I want to make is that English pronunciation must be taught; the teacher should be prepared to devote some of the lesson time to this, and get the student to feel that here is a matter worthy of receiving his close attention. So, there should be occasions when other aspects of English, such as grammar or spelling, are allowed for the moment to take second place.Besides this question of the time given to pronunciation, there are two other requirements for the teacher: the first, knowledge; the second, technique.It is also possible to get a clear mental picture of the relationship between the sounds of different languages, between the speech habits of English people and those, say, of your students. Unless the teacher has such a picture, any comments he may make on his students\' pronunciation are unlikely to be of much use, and lesson time spent on pronunciation may well be time wasted.What are the three important requirements for teachers in teaching?【单选题】

A.Attention, information, technique.

B.Time, knowledge, attention.

C.Time, knowledge, technique.

D.Information, technique, a clear mental picture.

正确答案:C

答案解析:第2段的意思是除了留出时间练习发音外，还有两个要求：其一是知识，其二是技巧，因此答案是C。

2、Important people don\'t often have much free time as their work occupies all their time.【单选题】

3、Working Successfully within Cultural BoundariesSoon after starting our job in China, we realized that the greatest challenge we faced would not be our day-to-day responsibilities but a completely foreign work environment and culture.We were used to the very direct, sometimes confrontational, but more equal style of management in the United States. Here, we were faced with the never-direct, never-confrontational style of management common in Asia.We often hear similar stories. One woman shared her experience of returning to China after more than 15 years in the US. Although she spent most of her childhood in China, she felt that her colleagues\' thinking processes were completely foreign to her. She needed to adapt herself to the culture of her company only then would she be successful at her job. In the end, she wasn\'t able to successfully re-adapt herself to the culture. What she didn\'t realize was that, rather than disagreeing with her ideas, they disagreed with her method of implementing them. For example, instead of recognizing her company\'s strict chain-of-command, she had in one case taken her plan straight to the company chairman. This action consequently caused her superiors to lose face. She had unwittingly broken a cardinal rule of Chinese culture.One man who spent many years overseas before returning to China to head up the local operations of a multinational company, had a similar experience. In his first management team meeting, he presented his plans for a new direction in China operations. His request was met with an uncomfortable silence, with none of the managers daring to speak up. They had not been prepared for his open style of management. Soon he quickly determined that his first on-the-job challenge would be to build up managers\' confidence in him, and that he had to do this individually, not in a group. Within a year, their management team meetings were transformed into the interactive, brainstorming sessions that he intended them to be.Therefore, it wasn\'t until after we had learned to appreciate the culture of our workplace and earned the confidence and trust of our inferiors that we were able to move forward and successfully do our job. We must first understand and accept a culture for what it is; only then will we be able to successfully work within it.What are the differences in style of management in the USA and China according to the author?【单选题】

A.In the USA, it is indirect style of management. In China, it is direct.

B.In the USA, it is direct style of management. In China, it is never-direct.

C.In the USA, it is always confrontational. In China, it is sometimes confrontational.

D.In the USA, it is equal. In China it is unequal.

正确答案:B

答案解析:根据第2段，文中说“我们习惯了美国的直接、有时针锋相对，但是更为平等的管理模式，但是在这里我们面临的是在亚洲普遍存在的不直接、不正面交锋的管理模式”，因此答案是B

4、In the process, the light energy converts to heat energy.【单选题】

A.reduces

B.changes

C.leaves

D.drops

正确答案:B

答案解析:在这个过程中，光能转化成热能。本题难度不大，converts指“转变”，通常与to或者into搭配，和changes“变化”是近义词，其他三项都是常用词，和答案意义差异较大，干扰性不强。

5、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global warming. Molecule for molecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a major factor of causing the global warming.Paragraph 5 ____【单选题】

A.Life of Macroscopic Bacteria in Livestock\'s Rumen

B.Ways to Reduce Methane\'s Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factor of the Greenhouse Effect
