说明文议论文主旨类题型
1.题干特征：
题干中出现main idea; mainly about; best / suitable title; 或问作者写文章的目的是什么
2.如何定位：
说明文和议论文文章的主旨多在首段，部分在尾段，或首尾段相结合，极少数需要自己总结如果议论文首段描写场景，那么主旨通常在第二段
3.方法：
1）如果首尾段的首尾句非常简短，且为总结性话语，那么很有可能是文章的主旨
2）如果首段提及研究(rearch; study 等)，那么通常研究结果为主旨
给出方式：
The rearch / study found / showed / suggested / indicated that …
The rearchers found / said that …
The result of the study indicated that …
…, according to the rearch.
…
注意事项：
2017年春节是几月几号如果首段提及previous (以前的) rearch，那么主旨应该是现在的或者新的研究结果
通常以前的研究是错误的或不全面的，个别是用来佐证最近的研究结果的正确性
通常大多数人的观点是错误的，后面会有转折给出正确的观点
吓组词3）如果首尾段出现转折，那么转折后是重点
可以表示转折的词语：
香菇青菜的做法
but; however; yet; while; instead (of)…
although; though; even if; even though; while (句首); despite … (强调主句)
actually; in fact; in effect; as a matter of fact; …
(un)fortunately; (un)luckily …
…
4）如果首段出现问句，那么问句本身或问句后的后一句(问题的答案) 很可能是文章主旨
注意事项：
如果问句在首段最后一句，那么通常这个问题本身是文章主旨或第二段给出的答案是文章主旨
5）如果文章介绍某人/ 物/ 事，那么介绍的内容为文章主旨
注意事项：
如果首段提及了介绍内容的优势好处或目的，那么优势好处或目的为主旨(help; benefit; …)
文章介绍某事件时可以把选项对应回首段，对应上的内容越多，正确率越高
行母表示目的的词语：
to do; in order to do; so as to do; intend to do; aim to do / aim at doing; mean to do …
6）寻找文章中的高频词
包月注意事项：
高频词通常要出现在选项中；
如果有两个或两个以上的高频词，那么最好所有高频词都出现在选项中；
如果有两个或两个以上的选项符合上述要求，那么需要注意选项中的不同之处，根据文章具体内容区分每个选项的侧重点，区分高频词之间的关系区别
4.如果询问主旨的题在文章的第一题提问，可以最后作答
