宾语从句 一 . 定义 简单的说 , 宾语 从句就是一个或是几 个从句充当主句中的 宾语成分。 二 . 主要类型 1） . 由连接代词(what , which , who, whose , whom)或 连接副词(when , where , why , how)引导。 连接代词 或连接副只是在某些动词后能用作宾语，这些动词有 , ask ,answer ,know , decide , wonder , understand , discuss ,show等等： e.g Do you know what he has said ? Can you tell me which class you are in ? Do you know what kind of person she is ? Let’s see how we can finish the hard work . Have you decided whom you would visit tomorrow ? Please show me where your passport is . Lucy still wondered why he couldn’t pass the exam . 2） . 由连词 whether 或 if 引导。（口语中常用 if ） e.g She asked me if she could borrow these books . Lily wanted to know if / whether her grandma liked the handbag . 注：1)中所列的动词后也常可用 whether , if 引导的 从句作宾语； e.g I’m wondering if the letter is over - weight . I don’t know whether this answer is right . 另外，这种从句前面有时还可以另有宾语。 e.g Please tell me which book I should read first . You may ask the man over there how you can get to the bus stop . Did she say anything about how the work was to be done ？ 3)由that引导。（ 在口语或非正式文体中常省略 ） e.g He knew ( that ) he should work hard . He said ( that ) he would like to see the Headmaster . 注意：在某些句型中，特别是带复合宾语的句子中， that 引导的从句常常移到后面去，前面用一个 it 作形式 上的宾语。(但是，有时 it 也可以省略） e.g We all thought it a pity that she couldn’t come . I took his word for it that he would try his best to help us .（他说他要想一切办法帮我们，我相 信他说的是真话。） I take it that we are to leave early .（我想我们 动身是会很早的。） 三 . 宾语从句中应该注意的一些情况 1.引导词 ?由陈述句变来的宾语从句，用连词 that 等引导，并且在口语中常常省略此词： e.g He said （ that ）he had a new dictionary . I know ( that ) Lucy can play football very well . 但是，如果 that 引导的是几个表示并列关系的宾语从句时，最后一个 that 不能省略。 e.g I know ( that ) Tom comes from France and that he teaches in a middle school in Guilin now . ?由一般疑问句转换而来的宾语从句，用 whether 或 if 引导，并且两词可以互用。但是 whether 可以和 or not 连用，而 if 不能。 e.g I want to know whether ( if ) she still lives there . Please tell me whether you can come or not . ?由特殊疑问句变来的宾语从句，由特殊疑问词 who , whom , whose , which , when , where , why , how 等 引导 。 e.g I don’t know whose book it is . Do you know where our English teacher lives ? The teacher asked what was happening . He wanted to know why you can play the piano so well . 2 . 语句的顺序 无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的 顺序。 e.g Could you tell me how I can get to the Science Museum ? He asked him where he came from .
