Working out helps you deal with stress in your job, relationships or any area of life. It is     1    (possible) because exercise is a form of stress itself and helps your body deal with it     2     a better way. Australian researchers found that those     3     did 30 minutes of aerobic (有氧的) exercise three times a week responded better to stress and had     4    (low) blood pressure.

Even     5     little exercise, from an easy 10-minute walk to intense aerobics, seems to decrease your feeling of anxiety.     6    (work) out regularly may make you smarter now and lessen the possibility     7     you’ll lose brain function at your age.

As the saying goes, “No one knows the value of health until he loses it.” From this, we know that health is     1     (true) important to everybody. But how to keep fit? Many people believe that sports can offer people health and pleasure. As far as I am concerned, doing physical exercise     2     (have) lots of advantages.

First of all, doing exercise in the morning will refresh my body as well as give me     3    good appetite to eat my breakfast. What’s more, the air in the morning is really fresh and clean , so I can keep my mind clear and sound in the class. By doing physical exercise every day I can keep my mind sharp ,     4     helps me finish my tasks in time. If I do not do any physical exercise for a long time, I     5     (feel) tired and my body becomes quite sluggish(浑身无力的). During the night, I may find     6     harder to fall asleep. Last but not least, doing exercise every day will help me build a better personality. It takes time and patience    7     (do) exercise .Sometimes I just want to give     8    , but my friend s encourage me to carry on. Then I feel a lot of satisfaction. Doing physical exercise makes me stronger and     9     (healthy). That’s my personal experience.

As a student, sports are necessary. You can pick up your favorite sport and do it every day. Only in this way can you build up your     10     (strong) and stay happy.

What on earth does happiness mean? I can’t give you its exact definition, but I’m sure if you love and help     1    , you will get it. I’ll never forget an old lady. She lives in a small house alone. It’s said that her husband and her son died in a road accident years ago.     2    life is bitter, but she often helps others with a smile. Whenever it snows,     3     is always the first to clean the paths.

She looks after several children living nearby. I am one of     4    . I often remember the stories she told us and her kind smile. Perhaps she is unlucky, but I think she is a happy person. Her life is full of laughter and love.

But I’m sad to see some people getting     5     happiness in bad ways. They talk noisily in cinemas and meeting rooms; they destroy trees to enjoy     6    and they laugh at     7     shortcomings. Perhaps they feel happy at that time, but they will never get true happiness because they have lost their personality already. Now I know     8     happiness is.     9     means kindness, love and unselfishness. Above all, I have come to understand that bringing happiness to others is getting     10     happiness.

It was the day of the poetry festival, and I was     1       (excite). At my old school, I had won the poetry ribbon every year. I do write good poetry. When Mrs. Baker called on me, I stood up. I didn't even bother to look at my paper. I'd spent so much time     2    (perfect) the rhymes, and counting the     3       (beat), that I knew the poem by heart. I had just started the third verse when I noticed Mrs. Baker was glaring at me. “Linda, you     4       (suppose) to be reading an original work, a poem you made up yourself, not reciting something you learned.” I opened my mouth to explain, but no words came out. “You will leave the room and will not return until you are ready    5    (apologize),” said Mrs. Baker. “Now. Go！” I turned and left the room. I'd been standing outside for about half an hour when Joseph, another school teacher, came over to ask me why. Now, as Joseph waited     6    me to answer, he looked so kind and sympathetic     7     I poured out the whole story, trying not to cry. “Linda, accepting defeat, when you should stand up for     8       (you), can become a very dangerous habit. You know you are the only Linda Brown in the whole world.”     9    eyes smiling into mine, I took a deep breath and     10    (knock) on the classroom door, ready to face Mrs. Baker — ready to recite my poem.
