宾语从句:
定义:在句子中作及物动词或介词的宾语。
基本形式:主句+ 关联词(关系词)+ 从句(主语+谓语...)
关于宾语从句关系词的选择:
1)若从句来源于一个陈述句,那么,关系词用that,that 没有任何词汇意义,不用翻译出来多数情况下that可以省略;
2)若从句来源于一个一般疑问句,关系词则用if 或whether(是否);
3)若从句来源于一个特殊疑问句,关系词就是疑问词(如what,who,where,when等)
宾语从句要注意的时态和语序:
主句是一般现在时,从句根据实际情况使用相应的时态。
I hope(that) everything goes well. 我希望一切顺利。
主句是一般过去时,从句使用过去的相应时态。
She didn’t know why he was late again. 她不知道他为啥又晚了。
从句表示的是客观现实、自然规律、名言警句、真理等,不管主句的时态如何,从句一律使用一般现在时。
We didn’t realize (that) the moon goes round the earth.
我们以前没有意识到月球绕着地球。
从句一律使用陈述句语序,即“主语+谓语形式”
宾语从句的否定转移:当主语的谓语动词是think,believe,suppose等词,且主句主语是第一人称时,若后面的从句要表示否定概念,一般将否定词not转移到主句的谓语中。
I don’t believe they will come here. 我不相信他们会来这。
以that 引导的宾语从句:当谓语动词表示肯定的概念,如hope, say, know, believe, expect, wish, think等词时,后面的句子一般用that引导,that没有词汇意义,通常可以省略。
例:I hope(that) you can understand me. 你希望你能理解我。
I don’t think (that) she will come here next week. 我不认为她下周会来这。

If/whether引导的宾语从句:当一般疑问句充当句中的宾语时,一般由if或whether引导,两个词意思为“是否”,不可省略。
通常情况下,两词可以互相代替,作用、意思相同。
只能用whether,不能用if的情况
在whether ...or not结构中,只能用whether,不能用if
Please tell me whether you have finished your work or not. 请告诉我你有没有完成作业。
当宾语从句放在句首表示强调时,只能用whether,不能用if
Whether you like English, I want to know. 我想知道你是否喜欢英语。
从句做介词的宾语时,只能用whether,不能用if
They are talking about whether the Chinese team will win the game.
他们在谈论中国队是否能赢得这场比赛。。
疑问词引导的宾语从句:当特殊疑问句充当句中的宾语时,由原来的疑问词what, who, which, where, when, how, why等作为连接词,这些词在句子中充当一定的句子成分,都有各自的词义,不可省略。在宾语从句中,后面的从句一定是陈述句语序。
Tell your mother what you want to do. 告诉你妈妈你想做什么。
I don’t understand why my parents’ ideas were different from mine.
我不理解我父母的意见为什么和我的不一样。
Could you tell me where you bought your dress? 你能告诉我在哪买的你的裙子吗?
注意:有些特殊疑问句本身就是陈述语序,在宾语从句中不用调整语序,如Which is the way to the nearest shop / What’s wrong with you / What’s up / What’s the matter 等
