回答题。

Can exercise be a bad thing？

Can exercise be a bad thing ？ Sudden death during or soon after strenuous exertion in the squash court or on the army training grounds, is not unheard of. 51 trained marathon runners are not immune to fatal heart attacks. But no one knows just 52 common these sudden deaths linked to exercise are. The registration and investigation of such 53 is very patchy ; only a national survey could determine the true 54 of sudden death in sports. But the climate of medical opinion is shifting in 55 of exercise, for the person recovering from a heart attack as 56 as the average lazy individual. Training can help the victim of a heart attack by lowering the 57 of oxygen the heart needs at any given level of work 58 the patient can do more before reaching the point where chest pains indicate a heart starved of oxygen. The question is, should middle-aged people 59 .particular be screened for signs of heart disease before 60 vigorous exercise ？

Most cases of sudden death in sport are caused by lethal arrhythmias in the beating of the heart, often in people 61 undiagn0sed coronary heart disease, In North America 62 over 35 is advised to have a physical check-up and even an exercise electrocardiogram. The British, on the whole, think all this testing is unnecessary. Not many people die from exercise, 63 , and ECGs (心电图 ) are notoriously inaccurate. However, two medical cardiologists at the Victoria Infirmary in Glasgow, advocate screening by exercise ECG for people over 40, or younger people 64 at risk of developing coronary heart disease. Individuals showing a particular abnormality in their ECGs 65 , they say, a 10 to 20 times greater risk of subsequently developing signs of coronary heart disease, or of sudden death.

根据以下材料，回答题

Smart Exercise

Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron， a scientist at Oregon Health and Science University， studies brain development. According to her research， it seems that exercise can make blood vessels， including those in the brain， stronger and more fully developed. Dr.

Cameron claims this allows people who exercise to concentrate better. As she says: "While we already know that exercise is good for the heart， exercise can literally cause physical changes in the brain."

The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies， even a little movement can show big results. Margaret Barnes， a pediatrician （儿科医师） ， believes in the importance of exercise.

She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory.

In this way， as they get older， children will begin to associate physical activity with higher learning，" says Margaret.

Older people can beef up their brains as well. Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult， but it does have to increase the heart rate. Also， just like the motion for infants， exercise for older people should involve some complexity. Learning some new skills or motions helps to open up memory paths in the brain that may not have been used for a long time.

For most people， any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain"s flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.

Research by Dr. Cameron seems to suggest that exercise can __________. 查看材料

A.generate new blood vessels

B.change the way a person thinks

C.promote brain development

D.divert one"s attention

根据以下材料，回答题

Exercise Can Replace Insulin （胰岛素 ） for Elderly Diabeties （糖尿病）

Most older people with so-called type II diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week， according to new medical research results reported in the Copenhagen newspaper Berlingske Tidende on Monday.

Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet"s Center for Muscle Research showed that physical exercise can boost the body"s ability to utilize insulin by 30 per cent， the newspaper reported.

This is equal tol the effect most elderly diabetics get from their insulin medication today， it said.

Researchers had a group of non-diabetic men and a group of men with type II， all more than 60 years of age， exercise on bicycles six times a week for three months. After the three months the doctors measured how much sugar the test subjects" muscles could utilize as a measure for how well their insulin worked.

Associate Professor Dr. Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilization as the healthy non-exercising persons.

"This means that the insulin works just as well for both groups. Physical exercise cannot cure people of diabetes， but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment."

Dela was quoted as saying.

Insulin is a hormone produced by the pancreas， controlling sugar in the body and used against diabetes.

Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat， but that the activity has to be maintained since it wears off after five days without sufficient exercise.

Most diabetics realize that they have to watch their diet while remaining unaware of the importance of exercise， Dela added.

How could most elderly type II diabetics stop taking insulin？ 查看材料

A.By taking more salt than usual.

B.By taking less salt than usual.

C.By doing brisk exercise for half an hour at least three times a week.

D.By going climbing， swimming or boxing every day.

根据下面材料，回答题。

What Makes Me the Weight I Am？

There"s no easy answer to this question. Your genetic makeup， the physical traits that get passed down to you from your parents， plays a big part in determining your size and weight.____46____ But if your parents are smaller than average， you may want to rethink that professional basketball career!

The same goes for your body type. Have you ever heard someone say a person is "big boned" ？

It"s a way of saying the person has a large frame， or skeleton. Big bones usually weight more than small bones.____47____

Like your height or body type， your genes have a lot to say about what your weight will be.

But that"s only part of the story. Being overweight can run in someone"s family， but it may not be because of their genes.____48____ And even though some kids gain weight more easily than others，when they eat right and exercise， most kids can be a healthy and happy weight that"s right for them.

It"s true——the way you live can change the way you look.

How much you weight is a balance between the calories you eat and the calories you use.

____49____ If you spend your free time watching TV， your body won"t use as many calories as it would if you played basketball， skated， or went for a walk. If you are in balance， your weight will stay right for you as you grow. But if you eat more and exercise less， you may become overweight.

根据以下内容回答题：

Homing pigeons are placed in a training program from about the time they are twenty。Eight days of age．They are taught to enter the lon through a trap and to exercise above and around the loft．and graduaUy they are taken away for short distances in wicker baskets and released．They are then expected to find their way home in the shortest possible time． In their training flights or in actual races，the birds are taken to prearranged distant point sand released to find their way back to their own logs．Once the birds are liberated，their owners，who are standing by at the home lofts，anxiously watch the sky for the return of their entries．Since time is of the essence，the speed with which the birds can be induced to enter the loft trap may make the difference between gaining a win or a second place． The head of a homing pigeon is comparatively small，but its brain is one quarter large than that of the ordinary pigeon．The homing pigeon is very intelligent and will persevere to the point of stubbornness；some have been known to fly a hundred miles off course to avoid a storm． Some homing pigeon experts claim that this bird is gifted with a form. of built-in radar that helps it find its own loft ager hours of flight，for hidden under the head feathers are two very sensitive ears，while the sharp，prominent eyes can see great distances in daytime． Why do homing pigeons fly homeg They are not unique in this inherent skill；it is found in most migratory birds，in bees，ants，toads，and even turtles，which have been known to travel hundreds of miles to return to their homes．But in the animal world，the homing pigeon can be trusted with its freedom and trained to carry out the missions that people demand．
