Most Americans clean their plates, no matter how full those plates are, a survey has found. The findings, released by the American Institute for Cancer Research on Thursday, add to the debate over how much restaurants and fast-food outlets are contributing to the epidemic of obesity (肥胖症) in the United States and elsewhere.The institute"s survey found that 69% of thosepolledfinish their meals most or all of the time, even when the portions are huge."Fully 30% Americans now say they generally base the amount of food they eat on the amount they are served,"according to the institute, which promotes research on the links between diet and cancer. "In a country where 64% of us are overweight or obese, there is an alarming tendency to overlook the sheer amount of food we"re eating," Dr. Barbara Rolls of Pennsylvania State University told a news conference.The report compiled information from two surveys involving 1,000 adults each. One was conducted in 2000 and the other in 2003. In 2000, 7% of those surveyed said they ate their entire meal all the time when dining at full-service restaurants. That number rose to 37% in 2003."Scientific studies show that people can and do unconsciously consume more calories-- as much as 56% more-- when served larger portions," the institute said. How many people are involved in the surveys conducted by the American Institute for Cancer Research
A. 370
B. 1,000
C. 2,000
D. 1,300
For years it has been possible to set up cameras to take pictures of cars as they speed along highways, jump lights or drive too fast down the street.However even if the pictures are taken automatically, someone still has to do all the paperwork of sending out fines. But now a British company called EEV has come up with a computerized video system that can do it all automatically.They suggest that all number plates have a bar code as well as the usual number. The bar codes are just strips of lines like those you see on food packets but bigger. EEV"s high speed video camera system can read a bar-coded number plate even if the car is doing over 100 miles per hour. The computer controlling the system could then use the information from the bar code to find out the name and address of the driver (from vehicle records), print out the fine and send it off automatically. The inventors also suggest that the system could watch traffic to help catch stolen cars.The new electronic system could be watching everyone that passes the cameras. Many people find the idea that "big brother is watching you" is more of a worry than a few motorists getting away with driving too fast. Moreover, some people will be very unhappy to realize that with new system the police could find out where a particular car has been. "Big brother is watching you" is more of a worry than...(Lines 2-3, para.4) means that many people ______.
A. are more worried about fast-driving motorists than being watched on
B. find “big brothers” more worrying than motorists
C. find motorists more worried than “big brothers”
D. are more worried about being watched on than about fast-driving motorists
Americans spend their free time in various ways.America is a country of sports---of hunting, fishing and swimming, and of team sports like baseball and football. Millions of Americans watch their favorite sports on television. They also like to play in community orchestras(管旋乐队), make their own films or recordings, go camping, visit museums, attend lectures, travel, garden, read, and join in hundreds of other activities. The people also enjoy building things for their homes, sewing their own clothes, even making their own photographs. They do these things for fun as well as for economy.But as much as Americans enjoy their free time, the country is at the same time a "self-improvement" country.More than 25 million adults continue their education, chiefly by going to school in the evening, during their own free time, at their own expense.Added to the time spent on personal activities, Americans also devote a great amount of their time to the varied needs of their communities. Many hospitals, schools, libraries, museums, parks, community centers, and organizations that assist the poor depend on the many hour citizens devote to these activities, often without any pay. Why do they do itThere are several answers. The idea of cooperating and sharing responsibility with one another for the benefit of all is as old as the country itself.When the country was first founded in 1776, it was necessary for the settlers to work together to live. They had crossed dangerous seas and risked all they had in their struggle for political and religious freedom. There remains among many Americans a distrust of central government. People still prefer to do things themselves within their communities, rather than give the government more control.Sometimes people offer their time because they wish to accomplish something for which no money is paid, to do something that will be of benefit to the entire community. It is true that some people use their leisure because they are truly interested in the work; or they are learning from the experience.No matter what the reason is, hundreds of thousands of so called leisure hours are put into hard, unpaid work on one or another community need. Which of the following is NOT true according to the passage
