they do not only look younger and slimmer, but feel better. Because of increased physical fitness, life
expectance in the nation has risen to seventy-three years, with fewer people suffering from heart disease,
the nation"s number one killer.
Jogging ( 慢跑 ), the easiest and cheapest way of improving the body, keeps over 30million people
of all ages on the run. For the price of a good pair of running shoes, anyone anywhere can join the race.
Dieting, too, has become a national pastime. Promoters of diets that eliminate eating one thing or another, such as fats or carbohydrates ( 碳水化合物 ), promise as much as 20- pound weight losses within two
weeks. Books describing such amazing diets always head up ( 居……之首 )the best-seller lists because people who are overweight want to lose weight quickly and easily.
Nevertheless, jogging and dieting, carried to extremes, can be harmful. Many confused joggers
overdo and finally suffer from ankle and foot damage. Dieting, fortunately, becomes only a temporary
means for shedding a few pounds while the body lose the balanced nutrition ( 营养 )it requires, so most
dieters cannot keep on diets. Above all, common sense should be the keystone for any dieting and
exercise plan.

Dad in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety
belt-a mistake 75% of the US population make every day. The big question is why.
There have been many myths about safety belts ever since heir first appearance in cars some forty
years ago. The following are three of the most common.
Myth Number One: It"s best to be "thrown clear" of a serious accident.
Truth: Sorry, but any accident serious enough to "throw you clear" is also going to be serious enough
to give you a very bad landing. And chances are you"ll have traveled through a windshield (挡风玻璃)
or door to do it. Studies show that chances of dying after a car accident are twenty-five times greater in
cases where people are "thrown clear."
Myth Number Two: Safety belts "trap" people in cars that are burning or sinking in water.
Truth: Sorry again. but studies show that people knocked unconscious (昏迷) due to not wearing
safety belts have a greater chance of dying in these accidents People wearing safety belts are usually
protected to the point of having a clear head to free themselves from such dangerous situations, not to be
trapped in them.
Myth Number Three: Safety belts aren"t needed at speeds of less than 30 miles per hour.
Truth: when two cars traveling at 30 m/ph hit each other, an unbelted driver would meet the
windshield with a force equal to diving headfirst into the ground from a height of 10 meters.
B. He didn"t have his safety belt on.
C. He was running across the street.
D. He didn"t take his medicine on time.
B. hated to drive in the dark
C. wanted to take some exercise
D. didn"t want to be caught by the police
B. may be knocked down by other cars
C. may find it impossible to get away from the seat
D. may get caught in the car door
B. Never forget to wear the safety belt while driving.
C. Try your best to save yourself in a car accident.
D. Drive slowly while you"re not wearing a safety belt.
You won"t be for long. Miami"s Mark Shantzis has made it simple for those living in tall buildings to use
the chute and recycle too.
In Shantzis" Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that
can turn around when operated. The system, which fits in the same space as the chute and container now
in use, enables glass, plastic, paper, metal, and other rubbish to go into separate boxes.
The system is controlled from a board next to the chute door. The board has a button for each class
of recycling materials (as well as for unrecyclables).At the press of a button, a microcomputer locks all
other floors" chute door and sets the recycling container turning until the right box comes under the chute.
The computer also counts the loads and gives a signal by phone when the box is full. And a particular
piece of equipment breaks up the nonrecyclables.
Sorting (分类) recyclables before they are collected saves the use of expensive materials recovery
equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very
expensive, so expensive that tons of recyclables remain wasted. Shantzis believes his system could help
recycled materials become more cost-effective.
B. to explain the need for rubbish collection in high rises
C. to describe the use of computer technology in recycling
D. to introduce a recycling system for high rises
B. rubbish chutes will become out of date before long
C. it won"t be long before you"ll have to recycle your rubbish
D. you won"t wait long for your turn to recycle rubbish
B. check if the container is full
C. lock the other floors" chute doors
D. break up the rubbish
B. it saves time and space
C. it saves money for people living in high rises
D. it reduces the cost of recycling
new study from Carnegie Mellon University shows anger may help people reduce the negative
impacts of stress and help you become healthier.
"Here getting emotional is not bad for you if you look at the case of anger," said Jennifer
Lerner of Carnegie Mellon. "The more people display anger, the lower their stress responses."
Lerner studied 92 UCLA students by asking them to count back from 6,200. They must say outloud
every thirteenth number. Researchers disturbed them by asking them to count faster or ask
them other questions. If they made any mistakes, they had to restart from the very beginning.
Many students felt depressed about making so many mistakes or got angry.
Lerner used a hidden video camera and recorded all their facial expressions during the test.
The researchers describe their reactions as fear, anger and disgust.
Other researchers recorded the students" blood pressure, pulse and production of a high-stress
hormone (荷尔蒙) called cortisol. People whose faces showed more fear during the experiment had
higher blood pressure and higher levels of the hormone. Both can have lasting effects such as
diabetes (糖尿病), heart disease, depression and extra weight gain.
When people feel fear, negative impacts increase, but when they get angry, those negatives
go down, according to the study.
"Having that sense of anger leads people to actually feel some power in what otherwise is
maddening (令人发狂的) situation," Lerner said.
Lerner previously studied Americans" emotional response to the 911 terrorist attacks two
months after the incident. She found people who reacted with anger were more optimistic. These
people are healthier compared with those who were frightened during the event. So in maddening
situations, anger is not a bad thing to have. It"s a healthier response than fear.
B. What you can do with anger in certain cases.
C. Different effects produced by anger and fear.
D. Healthier responses in maddening situations.
B. Blood pressure and pulse.
C. Blood pressure and cortisol.
D. Higher blood pressure and higher levels of the hormone.
A. By showing their optimistic side.
B. By reducing their stress.
C. By reducing high blood pressure.
D. By taking the place of fear.
B. asking them to count to 6,200 again and again
C. disturbing them and making them start all over again
D. criticizing them when they made mistakes
