Ⅲ.单句改错
1．I didn't know what one to buy because these books were all useful to me.
答案：what→which此处表示“不知道该买哪一个”意义，故“疑问词＋不定式”结构中的疑问词应用which。
2．You want to know that everthing is going in our school.
答案：that→how宾语从句的引导词在从句中作状语，表示go 的程度，表示“我们学校的情况如何”，故用how。
3．The problem is what the “Play” doesn't work at all.
答案：what→that表语从句的引导词在从句中不作成分，而且不表示意义，故用that。what在名词性从句中需要作主语、宾语等。
4．There is no doubt whether I will achieve great progress in English learning with your assistance.
答案：whether→that否定句或疑问句中doubt后的从句用that 引导，肯定句doubt后的从句用whether/if引导。There is no doubt that...“毫无疑问……”。
5．At that time, I just wondered that my mother was so delighted.
答案：that→why根据wonder判断，引导词表示“为什么”意
义，故用why。句子表示“我不明白为什么妈妈那么高兴”。
6．Which is worse, they spat and even threw rubbish into the lake.
答案：Which→What What is worse是固定用法，意为“更糟糕的是”。
7．I went up and asked what I could help them.
答案：what→if/whether宾语从句的引导词不需要在从句中作成分，再根据ask判断句子的引导词表示疑问意义，故应为if/whether。
8．As is known to all that millions of graduates crowded into the job market each year.
答案：As→It本句是一个it作形式主语，that引导的从句作真正主语的句子，故改为it。如果用as，则为As is known to all, millions of graduates...。
9．That you should learn is how to write down the most important words, not the whole sentence.
答案：That→What主语从句的引导词需要在从句中作learn的宾语，故用what。
10．The main reason for this was because my mother didn't know how to cook anything when she got married.
答案：because→that was后是表语从句且从句中不缺少成分，故用that引导。

英语语法：名词性从句语法讲解 时间：2016-10-08作者：来源：精品学习网 笔者在此就名词性从句中的几大易错点进行分析，希望对同学们有所帮助。 [关系代词和关系副词的误用] 例1 （2016·全国卷Ⅰ） My uncle is the owner of a restaurant close to that I live. 解析 that→where。本题考查宾语从句，引导词在从句中充当地点状语，所以将that改为where。 例2 （2015·全国卷Ⅱ） As natural architects， the Pueblo Indians figured out exactly thick the adobe walls needed to be to make the cycle work on most days. 解析 how。根据语境和空后的形容词thick可知应用how引导宾语从句，此处表示要弄清楚到底土坯房的墙需要“多”厚。故答案为how。 点拨若从句缺少主语、宾语、表语或定语，则考虑用关系代词；若从句缺少时间、地点、原因、方式等状语成分，则使用关系副词 （when/where/why/how）。 [if和whether的误用] 例3 He asked her the question if they can be friends. 解析 if→whether。question后为同位语从句，只能用whether来引导，故而将if改为whether。 例4 It doesn’t matter so much you will come or not. 解析考查主语从句。句意：你来还是不来，这不怎么重要。代词it作形式主语，真正的主语是whether引导的主语从句。 点拨在表达“是否”这一意思时，我们经常会用到whether和if，但以下几种情况只用whether不用if： 1. 在表语从句、主语从句、同位语从句中； 2. 在介词后的宾语从句中。如：It all depends on whether they will
