中考必考英语语法：宾语从句知识点全面解析（附练习题）

宾语从句是英语主从复合句中最常见的从句之一，也是考试必考的内容之一，宾语从句的用法一直是学习的重点、难点。 中考对宾语从句的考查主要集中在三点： 1. 连词的选择 2. 语序 任何从句都使用陈述句语序，宾语从句当然也不例外 3. 时态 ①当主句是现在时态时，宾语从句可以根据需要使用任何时态；②当主句是过去时态时，宾语从句必须是一种过去的时态；③当表示客观事实或普遍真理的句子做宾语从句时，任何时候都用一般现在时。 让我们一起走近宾语从句，揭开它的谜底吧！ 宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。根据引导宾语从句的不同连词，宾语从句可分为三类。 1. 由that引导的宾语从句。 That只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。例如： He said (that) he wanted to stay at home. She doesn’t know (that) she is seriously ill. I am sure (that) he will succeed. 2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。 Do you know who (whom) they are waiting foe? He asked whose handwriting was the best. Can you tell me where the No.3 bus stop is? I don’t know why the train is late. 3. 由if或whether引导的宾语从句。If和whether在句中的意思是“是否”。 I want to know if (whether) he lives there. He asked me whether (if) I could help him. 二. 宾语从句的语序 宾语从句的语序应为陈述句的语序。例如： I hear (that) physics isn’t easy. I think (that) you will like this school soon. Can you tell me how I can get to zoo? Please tell me when we’ll have the meeting. 三. 宾语从句的时态 1. 如果主句的时态是一般现在时，宾语从句该用什麽时态就用什麽时态。例如： I don’t think (that) you are right. Please tell us where he is. Can you tell me how I can get to the railway station? 2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时， 过去进行时， 过去将来时，过去完成时）。例如： He asked what time it was. He told me that he was preparing for the sports meet. He asked if you had written to Peter. He said that he would go back to the U.S. soon. 3. 如果宾语从句所陈述的是客观真理，其时态常用一般现在时。例如： Our teacher said that January is the first month of the year. Scientists have proved that the earth turns around the sun.
