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 |
