2018年公共英语五级作文指导：驳论性文章

　　It has been more than 30 years since man first landed the moon. Some people think that space research is a waste of money. Write an essay of no less than 250 words.

　　Example:

　　Whenever the debate of space research is raised among the general public, some people always emphasize that the space research is a waste of money. However, through decades of practices and observation, it turns out that this statement has many restrictions.

　　(Whenever the debate of online school is raised among the general public, some people always emphasize that they will replace the traditional schools. However, through decades of practices and observation, it turns out that this statement has many restrictions. )

　　Admittedly, the idea held by these people does contain an element of truth. But these arguers tend to ignore two other essential aspects.

　　First, these arguers fail to take into account the possibility that a country can make the best use of the cutting edge technology in the moon landing projects, thus profiting greatly from data transmission and rocket lift-off.

　　Second, the arguers’ assertion doesn’t provide sufficient data to narrow down the exact extent of the financial loss.

　　As a matter of fact, space research and exploration provides the primary incentive for the growth of satellite technology and the emergence of space shuttle, let alone other benefits from the discovery of rare material to the observation of new heavenly orbs.

　　In this respect, money return is not the sole hallmark of the space research.

　　Given reasons above, the arguments above, under a careful examination, turns out to be groundless in the hasty conclusion.(第一种结尾，重复自己观点)

　　In conclusion, the arguers’ evidence lends little credible support to her claim. To persuade people that space research is a waste of money, the arguers would need to provide clear evidence, sufficient data and thorough cost-benefit analysis of alternatives. (第二种结尾，反驳对方)
