例题：Huge reserves of energy have been found in rocks far below the surface of the ground in Britain. It is estimated that the north and southwest regions could hold enough energy in the form of heat to provide power for millions of homes. In fact, up to a fifth of Britain’s energy could be provided by this geothermal source. Extracting the heat and converting it into electricity is difficult and expensive. Thousands of bore holes would be needed; but once they were in place, the heat would keep regenerating indefinitely.

What is the writer’s main purpose in this paragraph?

A. to show how common the use of geothermal power is in Britain

B. to describe the problems related to using geothermal power in Britain

C. to highlight the potential benefits of geothermal power for Britain

D. to give a detailed description of how geothermal energy is produced in Britain

正确答案：C

答案解析：题干明确显示问的是writer’s main purpose，说明选项必须涵盖全文的主旨。选项中的“geothermal power，地热能”这个词可能部分同学并不认识，不过从文章第一句话就能看出它是指“reserves of energy … found in rocks”，而且就算不懂这个单词也完全不影响对接下来文章的解读。

通读文章后，通过缩句，筛去无关和修饰性内容，可以看到文章的重点是在文中蓝色字体部分，由此可以了解到文章是在说geothermal power的潜力，文中蓝字部分都是在用不同论据强调这一点，所以答案应该是C。
