学员北巴想：选新东方托福网络课堂学习吧，不会错的，它在2010年ETS 建立了托福考试全球研究院。新东方每年遴选出优秀教师派驻ETS 总部，参加Global Institute 的学习，新东方托福导学是全程能够联系你，你也可以随时联系的一个老师，他/她会帮您答疑和反馈问题。

学员加油吧：原本以为在线课程的话，会很难联系到老师并及时解决问题，结果出乎意料，老师回复问题超快而且很详细，如果没听懂多次提问，老师依然会耐心的解答，不能更赞！非常好，以后会给身边的朋友亲戚推荐新东方托福网络课堂学习的~~~

TASK4：

阅读标题： Fear Appeal

定义：When companies make advertisement to attract consumers, one of the strategies they adopt is called fear appeal. That is, they present some negative events or outcome people may encounter, and then provide solutions with their products or service.

听力例子：The professor uses a construction company’s advertisement about roof maintaining to explain fear appeal. In the advertisement, a family was at first having vacation on a beach, laughing and enjoying their vacation. But at the same time, back in their house, water leaks like rainstorm. When they get back home, they say damage everywhere. Then the voice comes: you can avoid this in advance; hire our company to check and repair your roof and you will never be worried about such thing.
