宾语从句核心语法总结
宾语从句三要素
(一)引导词
1. 引导陈述句的宾语从句,用that连接,that在句中无实际含义,通常可省略。
She says(that)she will learn to play the piano.(她说她要学弹钢琴)
We believe(that)hard work leads to success.(我们相信努力会带来成功)。
2. 引导一般疑问句宾语从句,用if或whether连接,两者均表“是否”。
He asks if/whether we will attend the meeting tomorrow.(他问我们明天是否参加会议)
I wonder if/whether the shop is open on weekends.(我想知道这家店周末是否营业)。
注意
有些场景只能用whether,比如介词之后、to do不定式之前,以及与or not连用。
I’m worried about whether I can pass the exam.
(我担心自己能否通过考试,介词后用whether)
She can’t decide whether to go abroad.
(她无法决定是否出国,to do前用whether)
Could you tell me whether you like the gift or not
(你能告诉我你是否喜欢这份礼物吗,与or not连用)。
3引导特殊疑问句的宾语从句,用特殊疑问词(who/whom/whose/which/what/when/where/why/how等)连接。
He doesn’t know where his keys are.(他不知道他的钥匙在哪里)
She asked how she could improve her listening skills.
(她问如何能提高听力水平)。
若主句和从句的主语一致,宾语从句可简化为“疑问词+to do”结构。 10. She wonders how she can get to the station. = She wonders how to get to the station.(她想知道怎么去车站)
He doesn’t know what he should do next. = He doesn’t know what to do next.(他不知道接下来该做什么)。
(二)语序
宾语从句必须用陈述句语序,即“引导词 + 从句主语 + 从句谓语”,不能保留原疑问句的倒装语序。
正确:Do you know where he lives
(你知道他住在哪里吗,从句用陈述句语序he lives)
错误:Do you know where does he live
(三)时态
主句是一般现在时,从句的时态根据实际语境灵活选择,可根据需要用一般现在时、一般将来时、现在完成时等。
Our teacher tells us that practice makes perfect.
(老师告诉我们熟能生巧,从句表客观事实用一般现在时)
I hear that they have visited Beijing twice.
(我听说他们已经去过北京两次了,从句用现在完成时)
He says he will go hiking next month.
(他说他下个月要去徒步,从句用一般将来时)。
3. 主句是一般过去时,从句通常要用相应的过去时态,保持时态一致。
She said she would come to the party.
(她说她会来参加派对,主句过去时,从句用过去将来时)
They told me they had finished their homework.
(他们告诉我他们已经完成作业了,主句过去时,从句用过去完成时)
