2 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Up to 82 percent of children with healthy mothers are not easy to be obese (肥胖的), according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only drinks wine in moderation,     2     significantly less likely to have a fat child, scientists say.

And research suggests it could be more to do with nurture (养育)     3     nature, as a mother’s lifestyle appears     4    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity is reduced even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children     5    nine to fourteen, born to almost 17,000 women in the US. Researchers looked at the link     6     overall mother health and likelihood of a child being obese. The mother’s health    7     (judge) on her height-to-weight ratio (比例), her diet, frequency of physical     8    (activity), smoking status and how     9     wine she drank.

A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

3 . Walking is the best form of exercise. It is good for the upper respiratory(与呼吸有关的)system and the legs. It helps us control our weight and blood sugar. Walking is also a good way to help you make more friends, bringing chances to see new things and meet new people. Personally I try to walk at least 5 miles daily.

As well as walking, I also cycle around Xiamen. Cycling is great for weight loss and helps to build stamina(耐力). However, cycling does not allow for the same level of social contact as a walk. It is for this reason that I would strongly suggest that you try long-distance walking if you want to be physically healthy. I originally(最初)started walking around Xiamen because I didn’t have a car, but I soon started to enjoy the walking for its own sake.

I have also made many friends during my walks. It’s not uncommon for my 5-mile walk to sometimes take as long as 2 or 3 hours,because I stop to chat with different shop owners along my route. These days, if I skip my walk for even one day, the people in the shops may want to know why I didn’t come.

I’ll never forget the first time some people followed me when I was walking, and asked if it was okay for them to walk with me. I really didn’t know what to say, so I just replied that I didn’t mind. I have been invited for lunch,dinner and sometimes just to sit and drink tea with total strangers. There is nothing more pleasant than walking past a schoolyard and hearing all the kids say hello to me.

4 . Can exercise during childhood protect you against memory loss many years later? Exercise early in life seems to have lifelong benefits for the brain, in rats at least.

“This is an animal study, but it shows that physical activity at a young age is very important — not just for physical development, but for the whole lifelong track of cognitive development during ageing,” says Martin of the University of Toronto, Canada. “In humans, it may put off the appearance of Alzheimer’s symptoms, possibly to the point of preventing them.“

Martin’s team divided 80 young male rats into two equal groups, and placed running wheels in the cages of one group for a period of six weeks. Around four months later — when the rats had reached middle age — the team taught all the rats to connect an electric shock with being in a specific box. When placed in the box, they froze with fear.

Two weeks later, the team tested the rats in three situations: exactly the same box in the same room, the same box with the room arranged differently, and a completely different box in a different room.

The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations, suggesting they couldn’t remember which one was dangerous. But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings.

“The results suggest the amount of physical activity when we’re young, at least for rats, has influence on brain and cognitive health — in the form of better memories — when we’re older,” says Arthur Kramer of Northeastern University in Boston, who has found that, in humans, exercise improves the growth of new brain cells.

6 . Playing sports offers you more than just physical benefits (好处).     1     The benefits are the same whether or not you’re good at sports. If you are not good enough to play competitively on a school team, you can play sports with your friends.

Making new friends.

Understanding the value of health.

Building team spirit.

This will without doubt help them in their future lives and jobs as well.
