o development—health problems such as overweight are all becoming more common, as more people take taxis to work instead of riding their bicycles, and other labour-saving devices become more popular.

An increasingly fast pace of life makes it difficult for people to spend time playing sports. " I know exercise is good for your health, " a young lady said, " But after a busy work week, the only thing I want to do is watching TV and going to sleep. " That attitude may explain the results of a recent nationwide study, which suggested 15 percent of urban adults in China have heart problems.

Local researchers found that 31. 2 percent of elderly respondents were getting enough exercise, but less than 9 percent of youngsters and the middle-aged got enough physical activity.

Elderly people understand the importance of protecting their health. The young people, however, are busy working and use this as an excuse to avoid exercise. In fact, physical exercise doesn't require much time, money or a special gymnasium. People can make use of any time and any place at their convenience to take part in sports. Walking quickly, cycling, climbing the stairs and dancing are all helpful methods to improve one's health.

The benefits of adding a little more activity to your life are priceless. " There is no need to be an athlete (运动员) , however, "a local doctor said. People should walk for 30 minutes a day and take part in some other physical activities three to five times a week. He warns, however, that people in poor physical shape should start slowly, and build up over time.

Passage Three

Feeling tired lately？ Has the doctor said he cannot find anything wrong with you？ Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong.

Then consider this, you might be in a state of subhealth. (亚健康)

Subhealth, also called the third state or grey state, is explained as a borderline (临界)state between health and disease. According to an investigation by the National Health Organization, over 45 percent of subhealth people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam time.

Symptoms (症状) include a lack of energy, depression, slow reactions, insomnia (失眠), agitation (焦虑)and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.

The key to preventing and recovering from suhhealth, according to some medical experts, is to form. good living habits, alternate work with rest, exercise regularly, and take part in open-air activities.

As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish, because they are rich in nutritional (营养的)elements—vitamins, and trace elements(微量元素)—that are important to the body.

Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化道). They also say that a balanced diet is very helpful in avoiding subhealth.

44. According to this passage, which of the following is RIGHT？

A. When you are in a state of subhealth, you should go to see a doctor and buy some medicine.

B. When you are in a state of subhealth, you should stay at home and keep silent.

C. When you are in a state of subhealth, you should find out the reasons and relax yourself.

D. When you are in a state of subhealth, you should have yourself examined in foreign countries.

Passage Two

Throughout history, humans have suffered from a condition that they have never been able to escape—ageing. Some researchers, however, believe we may be thinking about it in the wrong way. They say we should start treating ageing itself as a disease—one that can be prevented and treated.

Their hopes are founded on recent discoveries that suggest biological ageing may be entirely preventable and treatable. From a biological preventive, the body ages at different rates according to genetic and environmental factors. Tiny errors build up in our DNA and our cells begin developing faults that can grow into tissue damage, which leads to ageing and ageing—related diseases.

One of the leading figures in human life research, Aubrey De Grey, explains in an interview that their goal is to develop a set of therapies for middle-aged and older people that will leave them physically and mentally equivalent(相当的) to someone under the age of 30. “Of course, without wiping their memories,” he adds. But he doesn’t think that is will be possible to stop ageing altogether. He sees a future where “rejuvenation technologies” can be applied to old people in order to revert their cells to what they were like when they were in their youth, buying them extra time. The idea is that someone who is treated at the age of 60 will be biologically reverted to 30. But because the therapies are not permanent fixes. Their cells will end up becoming 60 years old again in another 30 years time.

21. By “treating ageing itself as a disease”, some researchers mean _____

A.Aged people are liable to diseases

B.Ageing can be dealt with like a disease

C.Ageing is a disease hard to cure

D.Ageing should be treated carefully

Humans age at different rates due to _____ reasons.A.Physical

B.Biological

C.Genetic and environmental

D.DNA and cell-related

What will happen if someone is treated with De Grey’s technology？A.He will stay young for a longer time

B.He will no longer grow old

D.He will live up to at least 60 years old

F.He will not get ageing-related diseases.

What does “rejuvenation” (para.3) possibly mean？B.Relating to cells

C.Relating to genes.

D.Becoming healthy.

E.Becoming young

The goal of De Grey’s research is to _____.A.Freeze people’s age

B.Make people younger

C.Stop ageing altogether

D.Adjust people’s memories
