Salt plays an important role in our daily diet. Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict -how just three grams less a day would affect heart disease in the United States.
The result: Thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings. Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year．
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams,or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University. Each gram of salt contains four hundred milligrams of sodiu(钠), which is how foods may list their salt content．
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative.The idea is to put pressure on food companies and restaurants. Critics call it government interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows that the calorie information on the menu can influence what parents order for their children. Ninety-nine parents of three to six year olds took part. Half had calories between the two groups for foods that the parents would have chosen for themselves. McDonald's menus clearly showing how many calories were in each food. Parents given the counts chose an average of one hundred two fewer calories when asked what they would order for their children. Yet there was no difference in calories between the two groups for foods that the parents would have chosen for themselves.
Study leader Pooja Tandon says even small calorie reductions on a regular basis can prevent weight gain over time.The study was published in the journal Pediatrics．
1.Which of the following benefits does less salt diet in the passage NOT cover?
A．The decrease of strokes B．The prevention of weight gain
C．Fewer heart attacks D．The drop in medical care cost
2.It can be inferred from the passage that _______.
A．Americans ate no more than 5 grams of salt per day in the 1970s

In many parts of the world，cars play an important role in daily life and many societies would not exist without them. So the idea that in 20 years’ time, no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean much saving，no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself, and it will not be owned by one individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.
According to Dr. David Davis，who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both world wars put together.
Davis says cars will be fitted with some intelligent devices to regulate the distance between one car and another. The car will automatically speed up, or slow down, to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people. By 2010, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car’s windscreen. And by 2020, cars will travel in convoy linked to each other electronically. Cars will be connected by an electronic tow bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the normal amount.” says Davis. “But all the others in the train would bum about ten percent 0f the normal amount, and so produce about ten percent of the pollution.”
1. We know from the passage that governments and car manufacturers ________.
| A. do not believe the prediction that no one will own cars by 2020 |
| B. are devoted to the technological revolution in car industry |
| C. consider the predictions seriously |
| D. have put the super-intelligent car into mass production |
2. Which of the following will be the characteristic of the cars of 2020?
| A. The car will speed up out of control． |
| B. We will own as many cars as we want． |
| C. All cars will be driven by computers． |
| D. Cars will produce more pollution than present ones． |
3.The leader of the research team believes that the present car culture will change because ________.
| A. cars play a very important role in daily life |
| B. many societies would stop functioning without cars |
| C. cars should not be owned by one individual |
| D. it causes many deaths to human society |
4.The expression closest in meaning to the phrase “in convoy” in the last paragraph is ________.
| A. in line B. sidelong |
| C. side by side D. shoulder to shoulder |
5. What will happen if cars are joined to each other electronically in 2020？
| A. Motorists will get a clear view of the road． |
| B. The weather condition will not have effect on motorists． |
| C. There will be less pollution caused by car． |
| D. All trains will burn less fuel than present． |
