高二英语语法必考知识点总结【第一篇】
省略
Ⅰ、状语从句中的省略用法
以if从句为代表的状语从句中的特殊省略用法：通常省略了it is，that is，there is/are。
Ⅱ、定语从句中的省略用法
关系词的省略 关系代词that，which，whom等在限制性定语从句中充当宾语且不位于介词之后时，可以省略；in which或that在先行词way后作方式状语从句时可省略。
Ⅲ、虚拟语气中if及should的省略
1、 当条件状语从句中有were，had，should等时省略if，把它们提至句首，形成倒装句。
2、 Suggest，insist，order，require等表示建议、要求、命令的动词后接的名词性从句中，谓语动词常用“should+动词原形”，should可以省略。
Ⅳ、不定式符号to的省略
1、 感官动词see，hear，feel，watch等和使役动词have，make，let等后接不定式作宾语时，不定式省略to。
2、 在特定语境中为了避免重复，当不定式再次出现时，在want，wish，hope，try，plan，like，love，hate后往往只保留to，而省略后面的动词。但不定式后有be，have时，也保留be和have。
Ⅴ、So和not的替代性省略
用于避免重复前面所说过的内容，替代词so/not替代肯定或否定的名词性从句。可与believe，do，expect，fear，guess，hope，say，speak，suppose，think，I’m afraid等连用
