Step Ⅲ　Post listening 听力技法——抓取主旨大意 在听力测试中快速抓取主旨大意是把握全文内容并作出合理预测的关键，同时也可用主旨大意排除部分不符合选项。 [技巧点拨] 1．听懂开头句，有利于快速把握听力语篇的主题。 2．捕捉语篇相关话题词汇，推测语篇主旨要义。 3．学会归纳总结，明确语篇话题主线。 [典题示例] 听力原文 M：We deep-fried fish three days ago in the kitchen but the unpleasant smell stays. W：There is a method you can try.Every time you make coffee，dry the leftover coffee grounds and keep them in small bowls，then place the bowls in the kitchen. 听力试题 What are the speakers talking about？ A．How to fry fish.　 B．How to make coffee.　　 C．How to remove a bad smell. [策略应用]　本题用到归纳总结和抓取关键词的方式。根据对话内容可知，他们在讨论如何去除异味，关键词为unpleasant smell stays，a method you can try，由此判断答案选 C。干扰项 A 中的“fry fish”和 B 中的“make coffee”均在材料中有所提及，属于“以偏概全”的干扰方式，有较强的干扰性。这就要求我们抓住对话的主线，而不要过于注重细枝末节。 学生用书第4页 核心词汇练全 enable vt.使可能，使发生(able adj.有能力的；ability n．能力；才能) enable sb to do sth　 使某人能做某事 be able to do sth 能够做某事，有能力做某事 have an ability to do sth 有做某事的能力　　 (1)In the past few decades，learning a foreign language has enabled (enable) people to communicate with others from different cultures.
