可持续发展（Sustainable development）







This is a wittily designed and thought-provoking piece of drawing. As is depicted, a worker is digging inside the earth. Obviously, he is exploring coal, oil or natural gas, as the caption indicates. The earth has become hollow as a result of the digging. The skyscrapers are about to collapse into inside the planet.
Evidently, the picture is meant to reveal the fact that human beings are running into an energy crisis. Taking a look around, we can find examples too numerous to list. Reports are often heard upon the shortage of such energy as coal, oil and natural gas. A number of factors may have led to the crisis, but the following are some critical ones. For one thing, those fossil fuels are limited in reserves, which also put a strain on their supply. For another, with the population explosion and development of modern society, the demand for energy has been soaring.
Confronted with the energy crisis, we should take a series of effective measures to save energy. On the one hand, it is high time that people all over the world realized the energy crisis and economized on the use of it. On the other hand, scientific researches should be encouraged to work out efficient methods of saving fuels and to seek new sources of energy.






醉酒驾 车





Given are three quite simple but rather thought-provoking drawings. As is revealed in the first one, two men were raising glasses of wine and toasting each other. In the second one, two cars ran into each other and we can imagine the drivers must be the two drinkers. In the last picture, the same two men were lying in the hospital, both with bandage on their legs.
Evidently, the pictures target at revealing an increasingly prent illegal practice: drunken driving. No one can have failed to notice the fact that a mounting number of people died or got injured in accidents resulting from drunk driving. In Hangzhou, China, for example, two innocent young people lost their lives in two accidents that happened within a very short period of time. Actually, the phenomenon has been so widespread that it has drawn nationwide concern.
To our relief, we can see pertinent laws and regulations have been worked out and enforced to punish those who drive after drinking. However, I believe that more can be done to prevent things from getting worse. For one thing, severer laws can be made and put into effect. For another, the sale of alcohol should be limited in restaurants.
