1、A Strong Greenhouse Gas
1 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.

2、Working Successfully within Cultural Boundaries
Soon 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

3、He put forward a plan for improving their working conditions【单选题】

A.lifting

B.converting

C.developing

D.bettering

正确答案:D

答案解析: improving和bettering都表示“改进、使变得更好”；lifting:提升、举起；converting：改变；developing:发展。

4、A Bad Idea
Think you can walk, drive, take phone calls, e - mail and listen to music at the same time? Well, New York's new law says you can't. And you'll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research and a shocking number of accidents that involved. people using electronic gadgets (小巧机械) when crossing the street.
Who's to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."
The young people are often considered the great multitaskers. ____ A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.
It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $650 billion a year, The estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers' time was spent on interruptions and recovery time before they returned to their main tasks.
【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The younger group did 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.And you'll be fined $ 100 if you do so on a New York city street.

正确答案:D

答案解析:本题有一定的难度。可用排除法和代入法。本题的上一句谈到了年轻人常被认为是能同时兼顾多个任务的，下一句又谈到了一项试验表明年轻人和年纪大的没有多少差别，所以可以推断此处应该表达转折的意义。回来看选项，把D代入文中，符合逻辑，答案是D。

5、The Race into Space
American millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth and eight days in space and from my viewpoint, it was two separate lives," Tito explained. He loved his time in space. "Being in space and looking back at earth is one of the most rewarding experiences a human being can have."
This kind of experience isn't cheap. It cost $ 20 million. However, Tito achieved his dream, so he was happy. "For me it was a life dream. It was a dream that began when didn't have any money," he told reporters.
On 30 April 2002, Mark Shuttleworth became the world's second space tourist. Shuttleworth is a South African businessman. At the age of twenty - eight, he also paid $ 20 million for the eight - day trip.
Both Tito and Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list for flights into space. The spaceship to take them doesn't exist yet.
Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it’s so expensive, only very rich people can go into space. They want space travel to be available to more people.
That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an island in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia and California, seven days in space, and a vacation in Tonga, for $2 million.
However, space flight is still very dangerous. Bill Readdy is NASA's deputy assistant administrator for space flight. He says that the chances of dying are about 1 in 500. Because of this, it may take time before space tourism really takes off. You might be able to go up, but will you come down?
Both Tito and Shuttleworth have climbed Mount Qomolangma.
【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有一定难度，需要认真阅读文章。首先带着题干提示词Mount Qomolangma迅速回到文章定位。第五段提到，许多人都喜欢冒险，他们也都想爬上珠穆朗玛峰，这里没有提到这两个人，再看其他段落，也没有提到两人爬珠穆朗玛峰的事情，所以本题是未提及的，答案是C。
