Every day my husband parked his car in the same open-air car park in Zimbabwe. On this particular day, he had been running to his car with a pile of office papers under his arm. As he opened the car door, he suddenly lost control of his body. He felt a stabbing pain in his arm, and became totally breathless and lost consciousness. As he fell down, half in, half out of the car, his last thought was “what a way to die”.

A young woman getting into her own car in the deserted car park noticed what was going on and at once ran to my husband’s aid, trying to bring his life back. Realizing time was important, she tried to move my husband to her car, calling the guard at the gate.

Fearing an ambulance would take too long to arrive, she felt it better to get to the hospital as quickly as she could. She raced through traffic lights sounding her car’s horn and rushed into the hospital, calling out, “I have an unknown man here who I think is having a heart attack.

Having realized he was in capable hands, the woman returned to the car park, found his keys on the ground, collected his papers and piled them in the car. Having seen my husband come out of a certain building each day, the security guard thought he knew where he worked. The young woman managed to locate his colleagues and they in turn contacted my niece, who waited for me to return home so she could break the news to me.

After careful tests it turned out that my husband’s disease had nothing to do with heart. We were naturally eager to find the kind stranger who had come to his aid. After some weeks we discovered where the young woman worked. She was overjoyed when my husband walked into her office with a huge bouquet of flowers. She said she required no thanks, and preferred to remain anonymous (匿名的).

We now live in a different country, but each Christmas my husband remembers her act of kindness and sends a gift. We regard every day of his life as a bonus, all thanks to this kind stranger.

1.From the passage, we can infer that _______.

A. a heart attack hit the writer’s husband suddenly

B. there were few people in the park that day

C. the young woman was at a loss at first

D. the woman was fined for breaking the traffic lights

2.Who told the writer the news of her husband’s illness?

A. The young woman.

B. The security guard.

C. The colleague of her husband.

D. The writer’s niece.

3.What might be the most suitable title for the passage?

A. The Gift of Life

B. An Act of Gratitude

C. The Attack of a Disease

D. The Story of a Young Woman

Losing weight comes with a lot of health benefits—including making your brain sharper.

There have been few studies of overweight and cognitive functioning, (認(rèn)知功能) possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Yet, it turns out that overweight may damage cognitive functions such as memory and attention. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.

Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.

The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.

1.There is less research on overweight and cognitive functions because researchers _____.

A. believe overweight only affects our body

B. have focused on ways to sharpen people’s mind

C. do not consider overweight a main cause for low cognitive ability

D. are clear about the relation between weight and mental functions

2.The result of Gunstad’s study shows that ______.

A. losing weight has little effect on people’s memory

B. losing weight can improve people’s mental functions

C. overweight people are likely to have psychology problems

D. overweight people’s abilities of concentration differ greatly

3.What is Gunstad planning to prove next in his research?

A. Overweight people will get smarter by taking more exercise.

B. Healthy diet is better than exercise in losing weight.

C. Traditional ways of losing weight are better than operation.

D. Slim people are smarter than overweight people.

4.Which of the following is the best title for the text?

A. Body Weight and Health

B. Losing Weight by Operation

C. Ways to Improve Mental Functions

D. Losing Weight to Sharpen Your Mind
