高中英语宾语从句四个要点讲解

　　一、高中宾语从句要点之时态的呼应

　　1. 如果主句是一般现在时、一般将来时或祈使句时，宾语从句可根据情况使用各种时态。例如：I hear she is here today(she was here yesterday/ she will be here tomorrow.)

　　2. 如果主句是一般过去时，宾语从句应使用过去时态的某种形式。例如：He said he was watching TV(he had swept the floor/ he would play football after school)。

　　3. 如宾语从句所叙述的是客观事实、自然现象或科学真理等，从句不受主句时态限制，仍用一般现在时。例如：Our teacher told us that light travels faster than sound.

　　二、高中宾语从句要点之引导词的使用

　　1. 当宾语从句由陈述句变化而来时，用that来引导从句，that常无具体意义，一般可省略。例如：Lin Tao thought(that)the TV play was very boring.

　　2. 当宾语从句是由一般疑问句变化而来时，要用if或whether来引导从句。例如：David asked his mother if/ whether she liked the dinner last night.

　　3. 当宾语从句是由特殊疑问句变化而来时，原句中的疑问词充当连接代词(如who， whose， what， which)或连接副词(如when， where， why， how)，引导宾语从句。例如：

　　Do you know what we can do on the island？I don’t know why Jane was late for school this morning.

　　三、高中宾语从句要点之语序的陈述化

　　宾语从句一般要用陈述句语序。例如：

　　When did he leave？ I want to know. →I want to know when he left.

　　Does the shop close at six every day？ Do you know？ →Do you know if/ whether the shop closes at six every day？

　　四、高中宾语从句要点之否定转移

　　当主句的谓语动词为think， believe， suppose等动词，且主语为第一人称时，从句的否定要转移到主句上。例如：

　　I don’t believe he is here on time， is he？

　　I don’t think Tom is the best student in his class， is he？
