    Research proves that nearly half of the cancers diagnosed(诊断) in the UK each year-over 130, 000 in total- are caused by life choices that include smoking, drinking and eating the wrong things.

    Tobacco(烟草) is the biggest factor, causing 23% for cases in men and 15.6% in women, says the Cancer Research UK report. Next comes a lack of fresh fruit and vegetables in men's diets, while for women it is being overweight. Lead author of the report, Professor Max Parkin, said: "Many people believe cancer is related to fate or in the genes(基因), and that it depends on luck whether they get it or not. Looking at all the evidence, it is clear that around 40% of all cancers are caused by things we mostly have the power to change."

    For men, the best advice appears to be: stop smoking, eat more fruit and vegetables and cut down on how much alcohol you drink. For women, again, the best advice is to stop smoking, but also watch your weight.

    In total, 14 lifestyle and environmental factors, such as where you live and the job you do, cause 134, 000 cancers in the UK each year.

    Some risk（风险） factors are well founded, such as smoking's link with lung cancer. But others are less well recognized. For stomach cancer, a fifth of the risk comes from having too much salt in the diet, data suggests. Some cancers, like mouth and throat cancer, are caused almost entirely by lifestyle choices. But others, like gall bladder cancer(胆囊癌), are largely unrelated to lifestyle.

    Public Health Minister, Anne Milton, said: "By making small changes you can cut your risk of serious health problems- giving up smoking, watching you drink, getting more exercise and keeping an eye on your weight."

    June 5th is World Environment Day. This makes us pay more attention to our environment. When Wang Boxuan, a Beijing high school student, uses up his exercise books, he does not throw them away. Each one is kept at his school with hundreds of exercise books that are given by other students. Then they are sold to a Beijing paper-making factory.

    The paper is recycled and used again by students and teachers in the school. At the same time, the money that is made from the sales goes to schools in Inner Mongolia(内蒙古). The government there uses the money to plant more trees and grass. This place is one of the sources(源头)of the sandstorms(沙尘暴)that often attack Beijing during springtime.

    Wang's school is one of the schools in the capital that take part in the \"green promise" environmental protection activity. So far, nearly210，000 students have taken part in the activity, collecting more than 87 tons of waste paper.

    Sometimes people call each other “scared-cat”, but have you ever thought about this expression? When a cat is frightened, its heart starts beating faster, its muscles get tense (紧张的), and there are changes in the chemicals in its bloodstream. Although the cat doesn't realize this, its body is getting ready for action. If the danger continues, the animal will do one of two things. It will protect itself, or it will run away as fast as it can.

    Something like this also happens to people. When we are excited, angry or scared by other feelings, our bodies go through many physical changes. Our hearts beat faster, and our muscles get tense. All of these changes make us more alert and ready to react. We, too, get ready to defend ourselves or run.

   Human beings, however, have a problem that animals never face. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger — or hit somebody — and regretted it later? Have you ever shouted at a teacher, told somebody you were lonely, or said you were in love, and then wished later you had kept your mouth shut? It isn't always clever to express your feelings freely.

    Does this mean that it's smarter always to hide (藏) our feelings? No! If you keep feelings of anger, sadness hidden away or bottled up inside, your body stays tense. Physical illness can develop. It can actually be bad for your health. (It isn't good to keep pleasant feelings inside either; all feelings need to be expressed.)

    Feelings that you keep all bottled up inside don't just go away. It's as if you bought some bananas and stuck them in a cupboard. You might not be able to see them, but before long you'd smell them. And if you opened the cupboard, chances are you'd see little fruit flies flying all over them. They'd be rotten (腐烂).

    You can try to treat feelings as if they were bananas in the cupboard. You can hide them and you can pretend they don't exist, but they'll still be around. And at last you'll have to deal with them, just like those bananas.

    Do you often run outdoors to keep healthy? Have you ever thought about how running helps to clean up the earth? Sometimes a creative mind can bring us a win-win(双赢)situation.

    Plogging, a new way to exercise, began in Sweden(瑞典).The name "plogging" comes from two words the Swedish(瑞典的)word "plocka", which means" to pick up(捡起)", and the word" jogging", which means "to run slowly". A Swedish man called Erik started the movement. He saw rubbish here and there when riding to work each day. He became worried about the dirty environment and decided not to go to work by bike any more. Instead, he began to run to work and pick up the rubbish at the same time. To his joy, more and more people followed him and soon plogging became popular.

    Many people choose plogging instead of just jogging because they think plogging is a good way to help clean up the earth. Sometimes rubbish is difficult to collect because it may scatter all around. But if the runners pick up the rubbish on the way, it is quite different. After all, many hands make light work. Another reason is that plogging burns more calories(卡路里).According to a research, plogging for 10 minutes burns 48 calories, while usual jogging for 10 minutes burns about 39 calories.

    Everyone on the earth should play a part in cleaning it up! It's time for us to take action together. So ready? Let's plog tomorrow!
