(我知道他。) 宾语从句: I know that he is a good student. (我知道他是个好学生。) 二、 宾语从句的三要素 引导宾语从句的连词主要有三种,对应三种不同类型的从句。 1. 连词 that 作用: 引导陈述句充当的宾语从句。that 在从句中不充当任何成分,也没有实际意义,在口语和非正式文体中常常可以省略。 例句: I think (that) you are right. 我认为你是对的。 He said (that) he would come. 他说他会来。 2. 连词 if 或 whether 作用: 引导一般疑问句充当的宾语从句。表示“是否”。它们在从句中不充当成分,但不能省略。 例句: I wonder if/whether he will come tomorrow. 我想知道他明天是否会来。 She asked me if/whether I had finished my homework. 她问我是否完成了作业。 if 与 whether 的区别: 一般情况下可以互换。 但从句中有 or not 或与 or 连用时,通常用 whether。 例句: I don't know whether he will come or not. 3. 连接代词或连接副词 作用: 引导特殊疑问句充当的宾语从句。它们既有连词的作用(连接主句和从句),又在从句中充当一定的成分(主语、宾语、状语等),不能省略。 常见词: what, which, who, whom, whose, when, where, why, how 例句: Do you know who he is 你知道他是谁吗?(who 在从句中作表语) Please tell me where you are from. 请告诉我你来自哪里。(where 在从句中作地点状语) I can't remember what he said. 我不记得他说了什么了。(what 在从句中作宾语) 三、 宾语从句的语序 宾语从句必须使用陈述语序,即“连接词 + 主语 + 谓语 + 其他”。 错误: Do you know where does he live (疑问语序) 正确: Do you know where he lives (陈述语序) 错误: I don't know what is his name. 正确: I don't know what his name is. 四、 宾语从句的时态 宾语从句的时态常常受到主句时态的影响和制约,称为“时态呼应”。 主句时态 从句时态 例句 现在时 或 将来时 (e.g., He says, I will ask) 根据实际情况,可用任何时态 He says he is/was/will be a teacher. 过去时 (e.g., He said, I thought) 必须使用相应的过去时态 (一般现在时→一般过去时;一般将来时→过去将来时;现在完成时→过去完成时) He said he was a teacher. (过去) He said he would come. (过去将来) He said he had finished his work. (过去完成) 时态例外情况: 如果宾语从句表述的是客观真理、自然现象、名言警句或习惯性动作,则无论主句是什么时态,从句都使用一般现在时。 例句: The teacher told us that the earth goes around the sun. (地球绕太阳转是客观真理) 1.They are talking about _____ can be the best monitor. A.who B.what C.which D.where 2.—I want to know _____ Tom gave up the match. —Because he hurt his foot.
