Reference answer : No, I don't think it is worthwhile disturbing the natural environment, no matter whether it is for economic developments or for technological achievements. As we know, nature is invaluable and fragile. If we spoil it at will, soon our world will become dullno more singing birds to hear, no more beautiful flowers to watch, no more fresh air to breathe, and no more crystal-clear
1. Do you think it is worthwhile disturbing the natural environment to develop human enterprise? What would it be like if people spoil the environment at will?
Reference answer : rivers to enjoy. Even worse, besides animals and plants, we human beings will also face the fate of extinction. Actually, during the recent decade, we have faced some environmental problems which are undoubtedly caused by modern technology or so-called “human enterprise.” For instance, cars enable us to travel easily, but their exhaust simultaneously pollutes the air and
Reference answer : contributes to global warming. As a result, we have sizzling summer and warmer winter. Icebergs in the polar regions melt. The sea level rises; seawater floods the coastal areas. If we keep spoiling the nature, the situation would get worse and some day we would eat the fruit of our own doing. In other words, we human beings would meet our doom.

Reference answer : Yes, I still remember it clearly. At that time, I was terribly frightened. The disease was like an invisible killer lurking around me. There was no efficient way to prevent it. Every day, I heard of scary news of increasing SARS cases and deaths on TV or radio. To make things worse, there was no cure for the disease. Even doctors and nurses were panicked. Some of them even refused to return to
Reference answer : hospitals to take care of SARS patients. At that time, I could not help wondering whom I should turn to if I had got SARS. I was afraid that I might become one of the victims of SARS. I was also afraid that I might lose my friends or family. It seemed hopeless then. The disease was not only a disaster but also a test to people in Taiwan. It tested us if we would make a stand for
Reference answer : humanity in the face of great danger. Obviously, we did poorly in the test, which was much more depressing than the fact that our medical science was not good enough to prevent such a disease. Therefore, I think, in the future, one of the best ways to lessen the danger caused by SARS is: we should hang together. We should take care of one another. We should do things for everyone's good, not
Reference answer : just for our own good. In short, “united, we stand; divided, we fall.” Back
