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 much more food can one consume unconsciously according to the scientific studies

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 ______.
