高考英语语法与知识点总结
高考英语语法与知识点：时态和语序
当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.
当主句为过去时
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
②从句过去完成时表示该动作发生在主句谓语动作之前
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后
④如果从句是一个客观真理，那么从句的时态不根据主句的时态而变化
⑤当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时，不能按正常语序安排，经常将这类引导词置于句首
无论任何时候都为陈述语序.但也有部分口语提问例外 E.G:What's the
matter?What's wrong with you?
高考英语语法与知识点：被动语态
一般现在时、一般过去时用be +及物动词的.过去分词，be有人称、时、数变。

完成时态havehasdone，被动将been加中间。

一般将来shallwilldo，被动变do为be done。

将来进行无被动，shallwillbe doing。

现在完成时，被动 havehasbeen done。

现、过进行be doing，被动be加being done。

情、助、有、是妥安排，一律随新主语变。

否定助后加not，疑问一助置主前。

主语恰是疑问词，直陈语序主在前。

一般情助加be done，双宾多将间宾变。

复合宾语宾变主，宾补、主补相应变。

第二句“be有人称、时、数变”即be有人称、时态和单、复数的变化。

“情助”是指情态动词和助动词“must，may，can，shall，will”等一律随新主语多是主动句中的宾语来变化。

“疑问一助置主前”是说有两个助动词的话，应把主语放在第一助动词之后或把第一助动词置于主语之前。
