宾语从句中的时态呼应和引导关联词 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用不同时态。 例如： he studies English every day. （从句用一般现在时） he studied English last term. （从句用一般过去时） I know (that) he will study English next year. （从句用一般将来时） he has studied English since 1998. （从句用现在完成时） 当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。 例如：The teacher told us that Tom had left us for America．  刷题王 单词快速记忆法 新概念英语青少版 2.疑问词 + ever和no matter + 疑问词的区别。  ①  疑问词 + ever可引导名词性从句，在主从句中要充当一定的部分。如：  Whoever breaks the rule must be punished.  You can choose whatever you like in the shop.  ②  疑问词 + ever还可引导让步状语从句。如：  Whoever breaks the rule, he must be punished,  Whatever you do, you must do it well.  ③  no matter + 疑问词只能引导让步状语从句。如：  No matter what you do, you must do it well.  No matter who breaks the rule, he must be punished. 1. ________ I think he is Charles.
