为什么我们要补充2019年全国III的七选五，主要是为了验证这种对号入座的方法是否可行，是否正确。
适用人群：选用这种方法答题需要具备强大的理论基础，你才能够选出正确答案。
注意：各种答题技巧需要自己总结，你去看别人整理的答题技巧对学习提高毫无帮助。当然如果你能学以致用，必定会事半功倍
全文无总标题经典例题【选自2019年新课标III】

【全文无总标题】那么第一段或最后一段就有总结性的意义。或者承上启下的作用。
下面的两个小标题一个是Do's，一个是Don't s，故选E
注释：判断一篇文章是否有具有承上启下的作用，需要根据文章类型去判断，并不是所有的句首都具有承上启下的作用，如果是那是具有小标题的文章，那么句首设空则不一定有承上启下的作用。如果是非小标题类，句首设空一般具有承上启下的作用。
Do's（注释：这就是小标题）

第37题空后有一个Questions，而选项中含有questions的只有G，故第37题选G
