1、A Bad Idea
Think you can walk, drive, take phone calls, e - mail and listen to music at the same time 7 Well, New York's new law says you can't. _____. 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. However, an Oxford University research suggests this perception is open to question. 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:F

答案解析:本题难度不是很大。可用排除法和代入法。本题的上文谈到纽约新的法律规定在走路开车时不能打电话,发邮件,听音乐,下文转到谈新法律发生效力时间,所以可以推断此处会继续跟着上文展开阐述,应该讲如果你做了会导致什么结果,回来看选项,把F代入文中,符合逻辑,答案是F。

1、Looking to the Future
When a magazine for high-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change color with the push of a buttons." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, the article was written in 1958 and the question was, "what will life be like in 1978?".
The future is much too important to simply guess about, the way the high school students did. So experts are regularly asked to predict accurately. By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded but would have space for farms and fields. People would travel to world in "airbuses" all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. ______ Does that sound familiar? If the exert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982".
If the professionals sometimes sound like high-school students, it's probably because future study is still a new field. Here is an example for future study. Economic forecasting, or predicting what the economy will do, has been around for a long time. But there have been some big mistakes in this field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers.
One forecaster knew that predictions about the future would always be subject to significant errors. In 1957, H. J. Rand of the Rand Corporation was asked about the year 2000, "Only one thing is certain," he answered. " Children born today will have reached the age of 43."
【单选题】

1、Houses of the Future
What will houses be like in thirty years' time? No one really knows, but architects are trying to predict. What will our home be like then?
Future houses will have to be flexible. In thirty years' time even more of us will be working from home. So we will have to be able to use areas of the house for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home. _____. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.
Everyone agrees that in thirty years' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "We'll be having a party this weekend. What food shall we cook?" And the machine will tell us what food we will have to buy and how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.
The house of the future will be personal, each house will be different. You will be able to change the color of the wall easily.You won't have to paint them-you'll be able to tell the wall to change the color! And if you don't like the color the next day, you will be able to have a new one. The only thing you won't be able to do is move the house somewhere else!
【单选题】

A.You will be able to change the color of the wall easily.

B.The only thing you won't be able to do is move the house somewhere else!

C.And the machine will tell us what food we will have to buy and how to cook it.

D.What will our home be like then?

E.The house of the future will have to grow and change with the family.

F.The kids might take their bedrooms with them as they leave.

正确答案:E

答案解析:本题的难度比上一道明显降低,考生只要认真阅读文章,不难确定答案。可用排除法和代入法。本题的上文谈到随着孩子的出生,成长,和离家,家庭组成就会发生变化,带来房子的布置也会相应发生变化,下文谈到房子需要不断改造以适应家变化的需要,很明显此处很可能继续谈论,房子的改变问题,回来看选项,使用排除法和代入法,可以确定E是正确答案。

1、Don't Rely on Plankton to Save the Planet
Encouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ______
Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron for a month. They found that 100 years later only between 2 and 13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month.
Rough estimates in the past have predicted similarly disappointing results."These are newer and better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."But
the take-home message is the same. Ocean fertilization is not the answer to global warming."
【单选题】

A.Its opponents argue, however, that it will stop global warming.

B.Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.

C.As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.

D.They found that 100 years later only between 2 and 11 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.

E."These are newer and better models,"

F.Ocean fertilization is not the answer to global warming.

正确答案:B

答案解析:前句的句意(可以直接借助句子中的核心结构判断句子大意):“一些人鼓励浮游生物在海洋里生长,认为这有希望从大气中去除二氧化碳”,B中的opponents fear和空白前句中的some. . . encourage形成语意对比。

F.The radar equipment of cars would make traffic accidents "almost unheard off'.

正确答案:A

答案解析:本题前面是主题句:But there have been some big mistakes in this field,too。主题句后面的句子应该是扩展句,点出big mistakes的内容或举例说明big mistakes。选项A就是big nustakes的一个例子。本题后面的句子说许多股票大跌,投资者破产,证明了预测的错误。所以选项A是正确的。
