Health is     1    most important thing in the world. Nothing is more important than health. If one takes away our money, houses, cars, or even our clothes, we can still survive.     2    if our health is taken away, it is certain that we surely die. That is why we always try to eat in a     3    (health) way and exercise often.

How can we keep healthy? In order to eat healthily, I usually avoid    4    (eat) food high in fat, like French fries or cookies,     5    are junk foods. I eat lots of vegetables and fresh fruit. Besides, I only eat a little meat.

On the     6    hand, doing exercise is very important. Taking exercise every day     7    (help) us build a strong body. Regular exercise is an important part of keeping me healthy.

What’s more, I think friends are important part of one’s health. I always feel better when I am with friends than alone. When I am with friends I always laugh. Laughing is also an important part of health. It is good    8    (stay) with my friends. By eating properly and exercising    9    (regular), I can keep my body at a proper weight. By spending time with my friends, I can keep my mind as well as my body happy. These things sound easy to do, but not many people can manage     10    . I think a strong will is necessary if we want to keep fit.

2 . Basketball is a great sport that is not only fun, but also brings children many benefits in different ways.     1    .

Playing basketball has physical benefits. Children are full of energy—they need to move, jump and run constantly. Basketball will allow them to control that energy in a positive way. It’s a full-body sport.     2     Since it’s a fast and dynamic sport, children need to follow the game and the continuous movement of the ball. The ball moves quickly from one side of the court to the other and the kids move at the same pace which helps improve both resistance and speed.

Playing basketball has cognitive (认知的) benefits. Children who practice playing basketball develop skills that help them fight against opponents and move around the court. This sport helps them increase their ability to concentrate.     3     Children will learn to assess surrounding situations and problems that may arise, and then find the best and fastest solution. The fast pace of the game encourages quick decision-making and stimulates their concrete and abstract thinking.

    4     Since it’s a team sport, basketball promotes sociability, coexistence and respect among peers. It’s ideal for shy children because they will have to learn to interact with other players. This is important both to get better at the sport and to have more fun. They will also learn important values like cooperation, teamwork and competitiveness.

    5     In fact, there are many other benefits. The most important thing is that it’s a very fast and fun sport. This tends to make the vast majority of children enjoy it.

3 . Training for a marathon (马拉松) requires careful preparation and steady, gradual increases in the length of the runs.     1    , buy the best-fitting running shoes you can find. No one can say which brand will work best for you or feel best on your feet, so you have to rely on your experience and on the feel of each pair as you shop. When you have found shoes that seem right, walk in them for a few days to double-check the fit.     2    . As always, you should stretch (伸展) at least ten minutes before each run to prevent injuries.

During the first week, do not think about distance, but run five minutes longer each day.     3    , it is wise to take a day off to rest. But during the next week, set a goal of at least a mile and a half per run.     4    . After two weeks, start timing yourself.     5    . Depending on the kind of race you plan to enter, you can set up a timetable for the remaining weeks before the race.
