(代词作宾语) • I know that he is a student. (句子作宾语) 基本结构：主句 + 连接词 + 从句 He said(主句) that (连接词) he would come later(从句). 1.7.2013 宾语从句的第一个要素是连接词。我们根据从句的类型来选择：陈述句用that，一般疑问句用if或whether，特殊疑问句就用原来的疑问词。这个规则非常关键。 ‹#› 连接词的选择取决于从句本身的性质： • 陈述句作宾语从句: 使用that(无意义，可省略) She said (that) she was happy. • 一般疑问句作宾语从句: 使用if / whether(意为“是否”) I want to know if/whether he will come. 注意：如果从句中有or not的话，一般只选用whether, 构成whether...or not • 特殊疑问句作宾语从句: 使用原疑问词 (what, who, when, where, why, how) Please tell me where you live. 2. 要素一：连接词 语法梳理 1.7.2013 宾语从句的第一个要素是连接词。我们根据从句的类型来选择：陈述句用that，一般疑问句用if或whether，特殊疑问句就用原来的疑问词。这个规则非常关键。 ‹#› 核心规则：无论主句是陈述句还是疑问句，宾语从句都必须使用陈述句语序。 即：连接词 + 主语 + 谓语 + ... 错误示例：He asked where did she go. (×) 正确示例：He asked where she went. (√) 特别注意：当疑问词本身就是从句的主语时，语序不变。 I know who lives next door. (who 是从句主语) 3. 要素二：语序 语法梳理 1.7.2013 第二个要素是语序。这是最容易出错的地方。请大家牢记：宾语从句永远要用陈述句语序，也就是“主语在前，谓语在后”。即使疑问句作从句，也要把助动词或be动词还原到主语后面。 ‹#› 时态呼应规则： • 主现从随意：主句是现在时，从句时态不限。 He says he is a student. / he will go tomorrow. • 主过从必过：主句是过去时，从句用相应的过去时态。 He said he was a student. / he would go the next day. • 真理从必现：从句是客观真理，永远用一般现在时。 The teacher told us the earth moves around the sun. 4. 要素三：时态 语法梳理 1.7.2013 第三个要素是时态。时态的选择主要看主句。主句是现在时，从句可以随便用；主句是过去时，从句也要用过去的某种时态。但如果从句说的是客观真理，那无论主句是什么时态，从句都用一般现在时。 ‹#› 【定义】当主句主语是第一人称(I/We)，谓语是think, believe等词时，从句的否定要转移到主句上。 【结构】I don't think he is right. (而非 I think he is not right.) 【规则】 1. 主语是第一人称 (I/We) 2. 谓语是表示心理活动的词 (think, believe, suppose...) 3. 时态为一般现在时 5. 特殊用法：否定前移 语法梳理 1.7.2013 最后，我们学习一个特殊用法——否定前移。当我们想说“我认为他不对”时，习惯上会说 "I don't think he is right"，而不是 "I think he is not right"。否定词not从从句转移到了主句上。这在口语和书面语中都非常常见。 ‹#› 1．I’m worried about ________ I can enter a good high school or not. A．what B．where C．whether 2．He wants to know ________ we can go with him or not. A．if B．whether C．when 3．I think ________ he is right.
