As we know, sport is very common in our daily life. People who usually compete in sports can be found everywhere. Why so many people love sports? __1__
Generally speaking, it is good for our health to do sports, such as basketball, football, table tennis, swimming, badminton, and so on. __2__ I have taken the swimming course this term, since I didn’t know how to swim. I find that swimming is very interesting and has many benefits for our bodies. On one hand, it can make our blood circulatory system run regularly. On the other hand, the muscles of our bodies can be massaged(按摩) under the pressure of water. All these are positively advantageous to our health.
__3__ It is known to us that some sports are team sports that involve several players or even more. When playing with others, people must face the situation of getting along with others. Through the sport games, strangers may go easily with others and make friends with each other. __4__ If you don’t know what to do, doing exercises may be a good idea because you can share the time and the fun with your friends.
__5__Yes, that’s right. But the advantages of sports are more than its disadvantages. We should follow the lead of sports athletes, as sports play an essential role in our life. Plenty of physical exercise will help you keep fit.

Whether it’s a carol（圣诞颂歌）service or an evening of karaoke in the pub, many people will enjoy a good old singsong this Christmas. Singing aloud will not just lift the spirits---it’s good for your physical health as well. Filling the lungs（肺）with air, increasing the heart rate and getting blood pumping round the body faster can all help our physical health.
For the past few years Heart Research UK has been Funding a Christmas campaign aimed at getting people singing, simply for the benefit it can bring. The organizer of the campaign says singing is a safe, simple and social activity that everyone can enjoy. “Singing is linked to long life, stress reduction, and general health protection. It also brings a great amount of happiness. It is impossible to sing well with a long face because it affects your pitch（音高）.”
Professor Graham Welch, who leads the International Music Education Research Centre at the University of London, has spent more than 30 years studying the effects of singing. He says that singing is a form of exercise. It means we’re also having a strong aerobic activity（有氧运动）when we’re singing, which results in increasing the feeling of pleasure while decreasing that of stress.
“And communal（共同的）singing—like in a singing group, a church service or even a singsong in the pub—helps improve our sense of self-respect. It increases our sense of satisfaction with ourselves, a greater sense of feeling included. ”
Helen Astrid, a singing teacher, also sees the great effects that singing brings. “It lifts us up on a spiritual level, it helps our self-respect, and it’s great for all ages from small kids to grannies—you can have a good sing and let your hair down.”
But she warns people not to have too many beers or glasses of wine, though a glass may help them gather courage before taking to the stage during the holidays.
【小题1】Heart Research UK holds a campaign to __________.

It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
　　As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
　　Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
　　These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
　　Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
　　We know a lot about our world, but there are still many answers that we do not have, and we are curious.
