Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and sports shirt—to the office. He hardly ever wears a necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”

More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday, but only on Friday. This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss Company, 85 percent of employers said that they believe that casual dress improves employee morale(士氣). Only 4 percent of employers said that casual dress has a negative effect on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”

【答案】

2.A

3.D

4.C

5.B

【解析】文章講述了在美國越來越多的公司允許員工穿休閑裝,并分析了這種情況的原因。

2.A 細節題。根據第一段最后一句I need to feel comfortable.可知A正確。

3.D 細節題。根據倒數4,5行Only 4 percent of employers said that casual dress has a negative effect on productivity.可知D符合要求,并不是所有的員工都支持穿休閑裝。

4.C 細節題。根據第2段What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.可知C正確。

Chinese reports say the country’s vast pool of cheap labor is getting smaller, which could hurt an economy that heavily depends on labor-intensive manufacturing.
The academy’s research shows that China’s rural labor surplus, the source of migrant workers for the country’s factories, is about 50 million people—far less than the previously estimated 150 to 200 million.
Jonathan Unger, director of the Contemporary China Center at the Australian National University, says fewer rural residents are willing to leave their farms today. This is partly because there are more employment opportunities in rural areas, and because agricultural prices have gone up.
“And at the same time taxes in the countryside, fees in the countryside have gone down because of new sets of government policies,” he explained. “So people are not eagerly forced in the way they were five, six years ago to leave the farm in order to earn enough money for their families.”
The Chinese Academy of Social Sciences says another reason for the reduced labor pool is the country’s population policy, which allows city residents to have just one child, and farmers up to two if the first one is a girl.
A UN study predicts that China’s workforce will reach its top in 2015 and then gradually drop. Some of China’s major manufacturing areas, such as Guangdong Province, already face labor shortages.
Some economists think these shortages are, at least for now, a regional rather than a national problem. Sun Mingchun, an economist with investment bank Lehman Brothers in Hong Kong, points out that there are still millions of people in China who can not find work.
57. According to the academy’s research, China’ rural labor surplus today is about _______.
A. 150 million      B. 50 million      C. 200 million      D. 175 million
58. The reason why many rural residents don’t leave their farms today is ________.
A. the farmers are older than before.
B. the farmers are lazier than before
C. the farmers have much more money
D. there are more employment opportunities and agricultural prices have gone up
59. Which of the following is TURE according to the passage?
A. A study of UN estimates China’s workforce will come to the top in 2015.
B. No a study shows millions of people can’t find work in China.
C. The country’s population policy isn’t a reason for the reduced labor.
D. Five years ago, few farmers left their homes to earn money for supporting their families.
60. According to some economists, the shortage of Chinese workforce __________.
A. is a national problem                     B. is a regional problem
C. is not a problem                         D. can be solved easily

Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might be difficult to imagine anything twice as big.

    All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags,bottles and containers—plastic products of all kinds.

    The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert,with light winds and slow moving water currents. The water moves so slow that garbage from all over the world collects there.

    In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste,resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full,lessening their desire to eat or drink.

    The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste,and from eating fish that swallowed waste. Divers can also get trapped in the plastic.

    Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier,another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.

    In August,2009,a team from the University of California,San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effect on ocean environment.

1. How did the writer introduce the topic of the passage?

A. By giving an example.

B. By listing the facts.

C. By telling a story.

D. By giving a comparison.

2.What do we know about the Great Pacific Ocean Garbage Patch?

A. It is made up of various kinds of plastic products.

B. It is a solid mass of floating waste materials.

C. It lies l60 000 kilometers east of California.

D. It is described as a kind of oceanic desert.

3.Why do people pay attention to the Great Pacific Ocean Garbage Patch?

A. Because it may prevent the flow of ocean water.

B. Because the polluted plastic articles will move up the food chain.

C. Because it may be from an island in the pacific.

D. Because ships may be trapped in the floating waste.

4. The purpose of writing this passage is to____________.

A. warn people of the danger to travel in the pacific

B. analyze what caused the waste patch in the pacific

C. give advice on how to recycle waste in the ocean

D. introduce the Great Pacific Ocean Garbage Patch

As China becomes increasingly urbanized (城市化), it has to find space for its urban and rural citizens as both groups become increasingly integrated. Experts suggest a possible model way may be “re-inventing” a “garden city”.

China’s mega-cities are bursting at the borders and the country is now undergoing the quickest and biggest urbanization in the history of mankind. It is estimated that by 2025, China will have 400 million more people living in its cities, raising its urban population to 900 million. Besides, new satellite towns are mushrooming on the urban fringes while city ring roads are rippling outwards into the countryside at amazing speed. Satellite maps collected by Professor Joshua Bolchover at the University of Hong Kong bring the problem sharply into focus. They track the changing rural-urban framework in the past 30 years, and suggest that cities are cruelly destroying surrounding rural land and rapidly reducing the amount of arable (可耕種的) land, which gives way to new residential blocks, new industrial zones, new financial centers and the other inevitable signs and signatures of economic growth.

This, however, is not sustainable growth pattern, especially when China has the world’s largest population to feed. So concerned urban planners are starting to note the social and physical effects of diaspora (大移居) when replaced rural communities are forced into the cities.

On the other hand, a trend of thought is gradually taking shape and this is the concept of the “garden city”, a combination of country and city that is being proposed by architects and city planners. Hua Li, from Tao Architects, is among the many professionals with such a voice. His argument is supported by a long-term study on this subject. As Hua says, the answer is to preserve patches of productive farmland within urban boundaries. Less transportation means we have fresh agricultural products at lower costs and less carbon emission in the city. And urban farmland can also be showcased for agricultural tourism and education.

The concept is already practiced at the grassroot level. Agriculture has gone into the air, up to roof and balcony in some communities in the cities. It’s common to see organic “hanging garden” on the roof of some traditional courtyard home. According to some people, the rooftop project translate to tangible (=" practical)" benefits, such as safe, nutritious vegetables, a cooler home in summer. Some say thanks to the tomatoes they plant that are natural insect killers, there’re fewer mosquitoes. Apart from these, it also contributes to better bonding with neighbors. Zhang, a doctor in Beijing, began creating his hanging garden five years ago. Since his garden became home to 30 kinds of vegetables and fruit --- all enough to feed his family, neighbors have enjoyed dropping by for a relaxing chat or just to see how well the lovely vegetables and fruit are doing.

Although people like Zhang are still rare and the greening of roof space with vegetables and fruit takes skill and energy, with more positive media exposure and advanced technology there is the prospect that garden city will become common practice in the near future. By then, cities will no longer look so gray when seen from the satellites.

1.Some experts suggest re-inventing a “garden city” because ______.

A.it is the only model way to save the cities

B.it helps stop destroying the rural areas

C.increasing urbanization takes place in China

D.China has the largest population to feed

2.What is the purpose of paragraph 2?

A.To show the experts’ concern about the increase of population.

B.To persuade people into supporting economic growth in cities.

C.To explain the reasons for the change of rural-urban framework.

D.To inform the readers of the consequences of quick urbanization.

3.In Hua Li’s opinion, a combination of country and city will ______.

A.benefit the environment and lower living costs

B.become a project that needs a long-term study

C.lead to more rural communities being replaced

D.attract more farmers to take tours in cities

4.Zhang is mentioned (Paragraph 5) to show that ______.

A.he achieves his dream to own a hanging garden

B.hanging gardens are becoming more popular

C.the garden contributes to a better neighborhood

D.he is a pioneer to practise the gardening concept

5.As for the concept of the “garden city”, the writer feels ______.

A.desperate         B.hopeful           C.disappointed       D.concerned
