The earth is getting warmer. People burn coal, oil and gas and this produces carbon dioxide, methane（沼气）and nitrous oxide. These gases, called “greenhouse gases”, prevent the heat of the sun from leaving the earth’s upper atmosphere and this makes the earth warmer
62.
A few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. According to what they found, the scientists say that during the next 50 years about 25% of land animals and plants will become extinct. More than a million plant and animal species will be extinct by 2050.
63.
More than 10% of all plants and animals will become extinct. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we could save many more plant and animals from extinction.
64.
The scientists studied some regions of the world with a very rich biology. These were Europe, Australia, Central and South America, and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill, to get cooler. In flat areas, such as deserts, plants and animals would have to move a very long distance to get cooler, so they are in grater danger of extinction.
65.
The scientists found that half of the 24 species of butterflies they studied in Australia would soon become extinct. 60% of the species in the Kruger National Park in South Africa would also die out, and more than 100% of the 300 South Africa plant species they studied would also become extinct. One of the plants in danger of extinction is the national flower of South Africa, the King Protea. They studied 163 tree species in the Cerrado region of Brazil and found that 70 would become extinct. Many of the plants and trees that live in the region live nowhere else in the world. In Mexico, they studied 1,870 species and found that more than 30% of these were in danger of extinction.
How often one hears children wishing they were grown-ups and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.
Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. What’s more, life is always presenting new things to the child — things that have lost their interest for older people because they are too well-known. But a child has his parents. He is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong.
When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.

Movie makers at one time worried that they might be put out of business by television. Recently, however, more and more people have been going to the movies. This may be partly because the economic situation in America has worsened. When at the movies, people forget their troubles, as they get involved in the story on the screen. Also, directors have recently been producing pictures that large numbers of people want to see.
Americans in the millions are returning to their love affair with the movies. Motion picture industry experts see two main factors responsible for this: an increased need by Americans to escape from economic worries and a large number of new movies with broad audience appeal.
Movie makers admit that their rising popularity is partly the result of poor economic conditions, which traditionally bring an increase in theater attendance. “When people are fearful about the future, they look for escape,” comments Jack Valenti, president of the Motion Picture Association of America. “In a shaded theater, with a 65-foot screen, you lose yourself for two and a half hours and people find this beneficial.”

Tourism wasn’t as important as it is today. In the past, only people with a good deal of money could travel on holidays to other countries. More people travel today than in the past because there is a growing middle class in many parts of the world; that is to say, people now have more money for travel. Special plane fares for tourists make travel less expensive and more attractive than ever before. One person doesn’t travel for the same reason as another. But most people enjoy seeing countries that are different from their own. They also like to meet new people and to taste new food.
Tourism causes many changes in a country and in people’s lives. People build new hotels and restaurants and train native men and women as guides to show visitors around interesting places. There’re new nightclubs and other amusements. International tourism is clearly a big business.
