3. Therefore, we should realize the importance of electricity. As electricity is insufficient in our country, we should be frugal in using electricity. We should make great efforts to produce more electricity.
90.6 Make Our Cities Greener
Recent efforts toward the greening of our cities have achieved much, although the results are still far from satisfactory. In recent years many trees have been planted in the cities and much care has been taken of the planted trees. In spite of all this, the greening process is relatively slow compared with cities in many other countries. For example, the green space available on average to each Shanghai citizen is only 0.4 Mu while every Londoner has more than 20 Mu.
We can benefit much from making our cities greener by planting trees. First, trees absorb carbon dioxide to produce oxygen which is essential to the health of human beings. Second, trees and other greenery make our cities more beautiful. Third, trees can also improve the climate of the cities.
Since we can get so much from making our cities greener, we should spare no effort to do that. We should plant more trees and take better care of them. We also should not cut down the trees. In a word, we should do everything to add to the greening of our cities.
91.1 Bicycle - An Important Means of Transport in China
The bicycle is the most common means of transport in our country. There are several reasons for that. First, most people are not rich enough to buy a car. Since the bicycle is not expensive, it is affordable by the average Chinese families. Second, China has a large population and the traffic is heavy. The bicycle has the advantage of being small in size. A road which can only allow two cars to pass may allow more than ten bicycles to run side by side. Finally, people enjoy riding a bicycle to school, to work and on outing. It is so pleasant and the exercise is good for people's health.
Compared with a car, a bicycle has its disadvantages and advantages. For instance, a bicycle is not fit for a long distance trip. A person who sits all day long in a car might get fat and unhealthy, while a person on a bicycle may gain good health and pleasure.
The bicycle is popular in China and it will remain so for a long time to come. Many things must change before cars became common in China. Therefore, in the foreseeable future, the bicycle will still be welcome.
91.6 Changes in People's Diet
From the chart we can see that during the past five years there have been great changes in people's diet. The greatest change occurs in grain consumption, which has dropped 4% from 49% in 1986 to 45% in 1990 in total food consumption. The second greatest change is in milk consumption, which increased from 10% in 1986 to 13% in 1990. But on the other hand, two trends can be observed in the consumption of meat and fruit and vegetables. From 1986 to 1989, meat consumption increased from 17% to 23% while that of fruit and vegetables dropped from 24% to 20%. From 1989 to 1990, meat consumption dropped a little to 21%, while that of fruit and vegetables increased a little to 21%.
What has caused the great changes in people's diet? The main reason, I think, lies in the improvement in people's income level. With the development of our society, people are becoming richer and richer, which enables them to purchase more nutritious food such as meat and milk. In the meantime, grain consumption in people's diet consequently dropped.
So from the analysis, we can draw a conclusion that our society is progressing and people are living a better life than ever before. We are now able to purchase more delicious and nutritious food, resulting in an improvement in our health.
92.1 Is Failure a Bad Thing
Failure is a common thing in our daily life. As students, we sometimes fail to get high scores in our examinations. When we play games, we might be beaten by others. And there are times when we fail to do satisfactory work. All these failures happen naturally and almost every one of us has such experiences.
