文档介绍：一、概述在句子中起宾语作用的从句称为宾语从句。宾语从句一般由下面一些词引导。 引导 引导 who whom whose what which when why where how 。 1. that 属于从属连接词,在宾语从句中没有实际意义, 只是起引导从语的作用。 1)作动词的宾语从句? We all know (that) ess calls for hard work. ?我们都知道成功需要付出艰辛的劳动。? We knew (that) he had made a mistake. ?我们知道他犯了一个错误。 2)在某些 be+ 形容词的结构后面也可以跟 that 引导的宾语从句。如 sure, certain, glad, pleased, happy, afraid, surprised, sorry 等。? I am sure that I have posted the letter. ?我的确把那封信寄了。? I am afraid that you are right. ?恐怕你是对的。【要点拓展】一般说来引导宾语从句的 that 可以省略。如果有多个 that 引导的宾语从句,第一个 that 可以省略,其他一般不省略。? I know ( that ) you are right. 我知道你是对的。? The doctor told me ( that ) I should take more water and that things would get better very soon 医生告诉我要多喝水,情况很快就会好转。 2. whether /if 在做“是否”解时引导宾语从句,常放在动词 know , ask , care , wonder , find out 等之后。在口语中常用 if。 whether /if 在宾语从句中不作任何成分,但含有“是否”的含义,在句子中不可省略。? I don ’ t know whether/ if this bike is hers. ?我不知道这辆自行车是否是她的。? Can you tell me whether/ if your father joined the Party in 1990? ?你能告诉我你父亲是不是 1990 年入党的? 【要点拓展】 whether/if 在表示“是否”,引导宾语从句时常可通用。但一下情况只可以用 whether 。?介词后的宾语从句用 whether 引导。 We are talk about whether we can get the chance. 我们再讨论我们是否可以得到这个机会。? whether 引导宾语从句可以与 or not 连用 He doesn ’ t know whether they will plant trees on Saturday or not .他不知道他们周六是否会去植树。? Whether 引导的宾语从句可以置于句首。 Whether they will join in the ic I don ’ t care. 他们是否参加野餐,我不在乎。?在不定式前只用 whether 。 I’ m just wondering whether to stay for another hour. 我不知道是否要再等一个小时。 who whom whose what which ?
