【编者按】为广大考生朋友整理了英语语法要点，同学一起来学习吧!
宾语从句作为一个重要的语法知识, 是每年高考的必考点,宾语从句使用也有很多应只注意的地方,今天我们就总结了高中英语宾语从今常见的四点错误,希望对同学们有用处!
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?
