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have(has)done,被动将been加中间。
一般将来shall(will)do,被动变do为be done。
将来进行无被动,shall(will)be doing。
现在完成时,被动 have(has)been 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。
