1、第第2课时高瞻远瞩课时高瞻远瞩锁定主旨大意类题目锁定主旨大意类题目怎么考主旨大意类题目主要考查全文的主旨大意、段落的中心思想，作者的写作目的和文章标题。常见的设问方式有：1.The main idea/key point of this passage is that _.2.The passage is mainly about _.3.The best title/headline for this passage is _.4.The topic/subject discussed in this passage is _.5.From the passage we can learn/
2、conclude that _.6.The last paragraph is chiefly concerned with _.7.Which of the following statements best expresses the main idea of the passage?8.Which of the following best states the theme of the passage?怎么学在平时的阅读练习中，注意文章的体裁，把握作者的写作目的与思路，学会抓主题句、主题段，关注文章的首段、尾段、每段的首句和尾句等。另外，掌握略读与细读的基本技巧，学会积累、寻找关键词像
3、the most important，finally等，像概括类词therefore，in a word等。怎么解做此类题目时做到：1.高瞻远瞩，不可以偏概全；不可以个人的思想代替作者的思想。2.在了解全文大意的基础上，仔细考虑选项内容与文章主题有没有联系；3.看选项内容对文章概括得是否正确；4.要注意选项中所给出的题目范围是否过大或过小。要避免以下三种错误：概括不够，过度概括，以事实细节替代概括性强的大意。5.找主题句的四个小窍门：(1)段落中出现表转折的词语(如however，but，in fact，actually，while，on the contrary，in contrast等)时
4、，其后的句子很可能是主题句。(2)首段出现疑问句时，对该问题的回答很可能就是主题句。(3)作者有意识地反复强调的观点，通常是主旨；反复出现的词语，一般为体现文章主旨的关键词。(4)表示总结或结论的词或短语有therefore，thus，in short，conclude，in conclusion等。【典例剖析1】体裁：议论文话题：睡眠词数：248时间：7(2016四川卷，D)A warm drink of milk before bed has long been the best choice for those wanting a good nights sleep.But now a
