　　从句 注意事项 典句示例 宾语从句 在主句的主语是第一人称单数，谓语为think，believe，suppose，expect等动词后面的宾语从句中，有时谓语尽管是否定意思，却不用否定形式，而将think等动词变为否定形式，这一现象称为否定前移 I don’t think you are right. I don’t suppose he cares，does he？ 有些动词带宾语从句时习惯上需要在宾语从句前加it，这类动词有：hate，enjoy，like，love，dislike，appreciate，see to，insist on，depend on等 I hate it when they talk with their mouths full of food. 一般情况下介词后只能用wh­类连接词引导宾语从句，但except，in，but等也可跟that引导的宾语从句。其他介词后面需要用that从句作宾语时，必须用it作形式宾语 Your composition is quite good except that the organization is a bit loose. You may depend on it that I shall always help you. 从句 注意事项 典句示例 宾语从句 动词find，feel，think，consider，make，believe等后有宾语补足语时，需要it作形式宾语而将that宾语从句后置 I think it necessary that we take plenty of boiled water every day. 在demand/desire/insist/order/propose/recommend/require/suggest/request/advise/command等表示“要求、愿望、命令、建议”等动词后，that从句中常用(should＋)动词原形 The teacher suggested that we(should)call off the plan. 在由doubt，doubtful引导的宾语从句中，如果主句为肯定句，宾语从句的连接词用whether/if，在否定句或疑问句中，宾语从句的连接词常用that We all doubted whether/if the news was true. I don’t doubt that he will pass the exam. 从句 注意事项 典句示例 表语 从句 和同 位语 从句 主句的主语是idea，advice，suggestion，order，request，requirement 等名词时表语从句的谓语用“(should＋)动词原形”形式 His suggestion is that we(should)change our course. 在order，suggestion，advice等名词后的同位语从句中，谓语动词要用“(should＋)动词原形”形式 His suggestion that we(should)hold another meeting to discuss the problem was adopted. 主语为名词reason时，表语从句中的连接词用that The reason for such a serious accident is that the driver was too careless and drunk. 特别提醒 连接词whether，if的区别 1.if引导名词性从句时，只能引导宾语从句或不在句首的主语从句 2.whether可以作介词宾语，而if则不能 3.whether后可以接不定式，而if则不能 4.whether后可以直接跟or not，构成whether or not，if则不可 It is not decided whether/if I’ll go abroad. It all depends on whether they will support us. He didn’t know whether to get married or to wait. I don’t care whether/if you come or not. I don’t care whether or not you come. 从句 注意事项 典句示例 特别提醒 二、that通常不可省略的情况 1.that引导的主语从句置于句首时； 2.当一个句子有两个或多个并列的宾语从句时，引导第二个和以后几个从句的that不可省略； 3.由it作形式宾语时，that引导的宾语从句中，that也不可省略。 三、wh­ever与no matter wh­的用法区别 wh­ever既可引导名词性从句，又可引导让步状语从句；而no matter wh­只能引导让步状语从句。 Whatever I said，he wouldn’t listen to me. ＝No matter what I said，he wouldn’t listen to me. 无论我说什么，他都不会听我的。 (让步状语从句) He would believe whatever I said. 我说什么他都信。(宾语从句) 另外，在whoever，whatever，whenever，wherever中，­ever起强调作用，意为“究竟、到底”。如： Wherever have you been？你究竟去了哪里？ 谢谢观看！ 第八讲
