{原创范例}    Admittedly, there is an opinion that the exploration of tourism exerts negative influences on environmental and cultural aspects.

For one thing, tourists are believed to produce severe environmental pollution, which breaks the ecological balance.

For another, such activities would definitely give rise to cultural conflicts between locals and visitors.

However, on no account can we lose sight that the government, the local residents as well as the travelers themselves gain benefits from the development of tourism.

To begin with, the municipal government is certain to increase the revenue income from this.

Besides, it is obvious that exploiting this resource would provide the local inhabitants with a large number of employment opportunities.

Last but not least, travelers can also broaden their horizon, and relieve the pressure accumulated from work or study.

2.Some people think that using animals for experimentation purpose is necessary for the development of science. To what extent do you agree or disagree?

本题关于拿动物做实验是否有利于科学的发展。在做brainstorming的时候，建议考生可以借助“十大论证原则”，将优缺点列举出来。

Pros:  经济原则，安全原则，生理原则

Cons:  道德原则，权利原则

经过筛选，正文结构安排如下：

{原创范例} Admittedly, there is an opinion that taking animals for the purpose of experimentation is unnecessary.

For one thing, they believe that such activities bring these animals unlimited suffering, which is inhumane and cruel.

For another, a range of animals rights’ protectors are worried that it is a behavior to deprive animals’ rights of living.

However, on no account can we lose sight that animals used for experiment are of great contribution to the development of science.

First and foremost, it is believed that certain kinds of animals, such as mice, share the same features with human beings.

Besides, animals used for experiment are much cheaper than human beings, which reduces the cost on researching.

Last but not least, scientists who use animals to conduct experiment are in the hope to test the safety and effectiveness of newly developed drugs before pilot testing on small group of patients.
