编辑点评： 很多参加GRE的考生在做GRE写作的时候都没有写提纲的习惯，这是非常不好的。提纲在GRE写作当中起到了至关重要的作用。从今天起，我们将对GRE issue进行分析，弄清写作思路，这样才能让GRE issue得高分。 At various times in the geological past, many species have become extinct as a result of natural, rather than human, processes. Thus, there is no justification for society to make extraordinary efforts, especially at a great cost in money and jobs, to save endangered species. 在过去不同的地质时期，许多的物种因为自然作用而非人类行为而灭绝。因此，人类社会为了挽救濒危物种而付出的巨大努力，尤其是以大量的资金和工作机会为代价，这样做是毫无道理的。 正文： As the problem of ecological becoming more serious, there is much controversy over the issue of whether society should make extraordinary efforts to save endangered species. Somebody claims that we do not have to spend a great cost in money and jobs to do that result from that at various times in the geological past, many species have become extinct because of natural. However, I do not agree this argument. Indeed, there are certain species would become extraordinary that is not relevant to human beings, however, which cannot be the excuse for society to shirk the responsibility to protect them. The Darwin s theory of evolution tells us that only the species which suit for the natural will live in the society. And there is also a saying in China that the fittest survive. To balance the ecological, natural itself will choose the best species that is useful, which will not destroy the biological system. However, since the human beings appeared, especially as the contemporary society developing, the extinction of the species is accelerated. This acceleration makes seriously influence on the natural, and destroys the balance of the geological. There is a mass of data showing that how many species disappeared every year, every day, every hour, even every second, which makes people extremely amazed. In recent years, the largest animal in the world--whale is catched and killed at a big quantity which used to making the whale oil and produce food for people s pets. As a result from human being s vanity and desire, many precious species are going to extinct. Undoubtedly, human being should be responsible for the destroys on the natural. |
