Too many cars have created a lot of serious problems in our world. Besides congestion(拥塞), accidents and fast fuel consumption(消费), cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death. Last winter, car fumes(烟雾) formed heavy smog over Beijing, making the sky gloomy for weeks and deteriorating people's health.
One possible solution is to design and develop clean cars and clean fuels. In Tsinghua University, campus buses are driven by electricity. In Beijing some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars to completely replace the traditional ones.
Another solution is to develop modern public transportation systems and restrict （限制）the use of private cars. If the price of petrol rises constantly and the public vehicles（交通车辆） are efficient and convenient enough, most people will not use private cars. And the total number of cars in big cities will reduce greatly.
On the whole, the elimination （根除）of air pollution needs the co-efforts from the government, the public and the environments. This problem will be solved only with the help of science and technology.What is the main reason for air pollution in big cities?

America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect American society in many ways — education, medicine, and business. Quietly, the aging of America has made us a very different society — one in which people have a quite different idea of what kind of behavior is suitable at various ages.
A person’s age no longer tells you anything about his/ her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29-year-old university president or a 35-year-old grandmother, or a 70-year-old man who has become a father for the first time. Public ideas are changing.
Many people say, “I am much younger than my mother or my father was at my age.” No one says “Act your age” any more. We’ve stopped looking with surprise at older people who act in youthful ways.

When several different people look at the same person, it’s not unusual for each of them to see different things; when you alone observe one behavior or one person at two different times, you may see different things. The following are but some of the factors that lead to these changing perceptions(感知认可)
(1) Each person’s perceptions of others are formed by his or her own cultural conditioning education, and personal experiences.
(2) Sometimes perceptions differ because of what we choose to observe and how we deal with what we’ve observed. It is not necessarily true that person’s perception is based on observations of a particular person. Your observations may be totally controlled by what others have told you about this person; or you may focus (聚集) primarily on the situation or role relationship. Most people do not use the same yardstick (标准)to measure their parents, their friends, and strangers.
(3) Sometimes we see only what we want to see or don’t see what may be obvious to others because of our own needs, desires, or temporary emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory (矛盾的) information is particularly obvious, but it can be done. We can ignore (忽视) the stimulus He’s basically a good boy so what I saw was not shoplifting.
We can reduce the importance of the contradictory information — All kids (孩子) get into mischief (顽皮). Taking a book from the bookstore isn’t such a big deal. "We can change the meaning of the contradictory information." It wasn’t shoplifting because he was going to pay for it later. (from www.nmet113.com)

Biomass energy (生物能).often forgotten as a promising alternative (替代物) to oil, received its day in the sun with the gathering of the Bio-Energy World Congress and Exposition in Atlanta, Georgia, late in April, 1990. Nearly 1, 700 scientists, businessmen, and policy-makers, one-quarter from the foreign nations, gathered for a week to discuss various means of squeezing usable energy out of trees, crops, manure, seaweed, algae, and urban waste. Biomass in the United States contributes 2. 5 percent of the total supply, but this amount can be doubled by 2000 and then doubled again by the year 2010.
Eight percent of Sweden’s energy supply, for example, is presently coming from wood bark and pulp remainings, Sweden intends to raise this percentage by more intensive harvesting of waste food lying around in forests, and through the planting of so-called energy forests of fast-growing trees such as willow and birch.
Brazil is frequently pointed to as a nation with a major successful investment (投资)in energy coming from grains: it presently runs 330,000 automobiles on a water and alcohol (酒精) mixture, replacing 10 percent of its previous oil supply. Brazilian representatives (代表) at the conference said they wish to double this in five years, with a final goal of total replacement. Most of the cars are built at the factory to use the mixture, while older models are changed through low-cost government programs.
