Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime, it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steer them away from fast food shops and bad eating habits.

Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.
Hidden deep in our subconscious is an idyllic(牧歌般的,田园诗式的)vision. We see ourselves on a long trip that spans the continent. We are traveling by train. Out the windows, we drink in the passing scene of cars on nearby highways, of children waving at a crossing, of cattle grazing on a distant hillside, of smoke pouring from a power plant, of row upon row of corn and wheat, of flatlands and valleys, of mountains and rolling hillsides, of city skylines and village halls. But uppermost in our minds is the final destination. On a certain day at a certain hour, we will pull into the station. Bands will be playing and flags waving. Once we get there, so many wonderful dreams will come true and the pieces of our lives will fit together like a completed jigsaw puzzle. How restlessly we pace the aisles, damning the minutes for hanging around—waiting, waiting, waiting for the station. “When we reach the station, that will be it!” we cry. “When I’m 18.”; “When I buy a new 450SL Mercedes Benz!”; “When I put the last kid through college.”; “When I paid off the mortgage!”; “When I get a promotion.”; “When I reach the age of retirement, I shall live happily ever after!” Sooner or later, we must realize there is no station, no one place to arrive at once and for all. The true joy of life is the trip. The station is only a dream. It constantly outdistances us. “Relish(享受)the moment” is a good motto, especially when coupled with Psalm 180: 24: “This is the day which the Lord hath made; we will rejoice and be glad in it.” It isn’t the burdens of today that drive men mad, it is the regrets over yesterday and fear of tomorrow. Regret and fear are twin thieves who rob us of today. So stop pacing the aisles and counting the miles. Instead, climb more mountains, eat more ice cream, go barefoot more often, swim more rivers, watch more sunsets, laugh more, cry less. Life must be lived as we go along. The station will come soon enough.

One reaction to all the concern about tropical deforestation(毁林) is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"

The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.

Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.

Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.

Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.

Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.

Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
