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.

Food makes us feel good, but some people eat when they aren’t really hungry and eat to simply feel good. This kind of eating habit is called emotional eating, which does not affect adults but also young children. It isn’t a good thing.

A child’s eating habits can develop right from childhood. As we know, a baby cries out if he doesn’t get milk at the usual time of the day. However, sometimes parents immediately stick a bottle in a child’s mouth without trying to find out if the child is really hungry. In fact, children may cry for other reasons. Even as children grow up and start going to school, parents sometimes give them a chocolate bar if they become really unhappy. As the children further grow up, they may become used to having a snack whenever they’re upset or low.

Therefore, they’d like to eat an emotional snack when they have the feeling of unhappiness and boredom. Even when they don’t get high grades, aren’t popular at school or made fun of by others, they will want something to eat. After having the snack, they feel a lot better.

Emotional eating in young children is a thing that needs to be taken seriously. To protect your children from emotional eating, you should satisfy your child’s emotional needs in the best possible way. This includes spending time with your child every day, taking an interest in his school work, helping your child study, providing a health environment without tension at home, etc. Don’t make the child lose face by scolding him. Develop confidence in your child. Make your child eat enough once in a while. Reward him for his achievements.

All this will help your little one develop a healthy eating habit. And always remember love and care is the key to help you child out of trouble and grow up happily.

【小题1】What is the main reason for air pollution in big cities?

There are many older people in the world and there will be many more. A little-known fact is that over 60 percent of the older people live in developing countries. According to the World Health Organization, by 2020 there will be 1 billion, with over 700 million living in developing countries.
　It is a surprising fact that the population aging is particularly rapid in developing countries. For example, it took France 115 years for the rate of older people to double from 7 percent to 14 percent. It is estimated to take China a mere 27 years to achieve this same increase.
　What are the implications of these increased numbers of older folk? One of the biggest worries for governments is that the longer people live, the more likelihood there is for diseases and for disability. Attention is being paid to the need to keep people as healthy as possible, including during old age, to lessen the financial burden on the state.
　Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries, certainly in Asia, older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily, which does not make sure the continued high regard of older people. As society changes, attitudes will change.
　Much needs to be done to get rid of age discrimination in employment. Life-long learning programs need to be provided to enable older people to be active members in a country’s development.
　Social security policies need to be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net.
