Unit 4 语法:宾语从句(疑问词引导)
一、语法讲解
(一)疑问词引导的宾语从句概述
1. 定义
疑问词引导的宾语从句,是指由特殊疑问词(what,which,who,whom,whose,when,where,why,how等)引导的宾语从句。这类宾语从句来源于特殊疑问句,在复合句中充当宾语成分。
2. 结构
主句 + 疑问词 + 宾语从句(主语 + 谓语 + 其他)
疑问词在从句中保留其疑问含义,但整个从句使用陈述句语序。
例句:I don't know what he is doing.(我不知道他在做什么。)
3. 与that和if/whether引导的宾语从句的区别
· that引导的从句:表达陈述性事实,that无意义。
· if/whether引导的从句:表达“是否”的疑问,从句内容为yes/no问题。
· 疑问词引导的从句:表达“什么、哪里、何时、为什么”等具体疑问信息,疑问词有意义。
(二)疑问词的分类及用法
1. what引导的宾语从句
what在从句中可以作主语、宾语、表语或定语,意为“什么”。
例句:
· what作主语:I don't know what happened yesterday.(我不知道昨天发生了什么。)
· what作宾语:Can you tell me what you are doing?(你能告诉我你在做什么吗?)
· what作表语:She asked me what my name was.(她问我叫什么名字。)
· what作定语:I don't know what color he likes.(我不知道他喜欢什么颜色。)
2. which引导的宾语从句
which表示“哪一个”,通常表示在一定范围内选择,在从句中可作主语、宾语或定语。
例句:
· which作主语:I wonder which will win the game.(我想知道哪个会赢得比赛。)
· which作宾语:Tell me which you prefer.(告诉我你更喜欢哪一个。)
· which作定语:She asked which book I bought.(她问我买了哪本书。)
3. who/whom/whose引导的宾语从句
· who:指人,在从句中作主语或表语。例句:I don't know who broke the window.(我不知道谁打破了窗户。)
· whom:指人,在从句中作宾语(口语中常用who代替)。例句:She asked whom I met at the party.(她问我在派对上遇到了谁。)
· whose:表示“谁的”,在从句中作定语。例句:I wonder whose bag this is.(我想知道这是谁的包。)
4. when/where/why引导的宾语从句
· when:询问时间,在从句中作时间状语。例句:Can you tell me when the train will arrive?(你能告诉我火车什么时候到吗?)
· where:询问地点,在从句中作地点状语。例句:I don't know where he lives.(我不知道他住在哪里。)
· why:询问原因,在从句中作原因状语。例句:Do you know why he was late?(你知道他为什么迟到吗?)
5. how引导的宾语从句
how表示“如何,怎样”,可以单独使用,也可以与其他词搭配使用。
例句:
· how单独使用:She taught me how I should use the computer.(她教我如何使用电脑。)
· how many + 可数名词:I wonder how many people came to the meeting.(我想知道有多少人来了会议。)
· how much + 不可数名词:Can you tell me how much this dress costs?(你能告诉我这条裙子多少钱吗?)
· how long:询问时间长度或长度。例句:I don't know how long he will stay.(我不知道他会待多久。)
· how far:询问距离。例句:Can you tell me how far it is to the station?(你能告诉我到车站有多远吗?)
· how often:询问频率。例句:I wonder how often he exercises.(我想知道他多久锻炼一次。)
· how soon:询问多久以后。例句:Please tell me how soon he will come back.(请告诉我他多久以后回来。)
6. whatever,whoever,whichever等复合疑问词
这些词引导的宾语从句表示“无论什么”、“无论谁”、“无论哪个”,带有强调或让步的含义。
例句:
· You can take whatever you like.(你可以拿你喜欢的任何东西。)
· I'll support whoever you choose.(我会支持你选择的任何人。)
(三)疑问词引导的宾语从句的语序
1. 基本规则:陈述句语序
无论疑问词本身是什么,从句必须使用“主语 + 谓语”的陈述句语序。
错误示例:
· Could you tell me when does the train leave?(疑问句语序,助动词does提前)
· I don't know what is his name.(疑问句语序,be动词is提前)
· She asked where did he go.(疑问句语序,助动词did提前)
正确示例:
· Could you tell me when the train leaves?
· I don't know what his name is.
· She asked where he went.
2. 特殊情况:疑问词本身就是主语
当疑问词在宾语从句中充当主语时,从句的语序与陈述句语序自然相同,无需调整。此时疑问词后直接跟谓语动词。
例句:
· I don't know who came to the party.(who作主语,后面直接跟came,语序正确)
· Can you tell me what happened?(what作主语,后面直接跟happened,语序正确)
· She asked which is better.(which作主语,后面直接跟is,语序正确)
3. 注意区分疑问词作主语和作宾语
作主语时,语序不变;作宾语或状语时,需要调整语序。
对比:
· I don't know who broke the window.(who作主语,语序不变,主语+谓语+宾语)
· I don't know who you met.(who作met的宾语,正常语序应为you met who,改为宾语从句后who提前,剩余部分you met保持陈述句语序,正确)
(四)疑问词引导的宾语从句的时态
时态规则与that/if/whether引导的宾语从句相同,遵循主句和从句时态一致性的原则。
1. 主句为现在时
从句可根据需要使用任何时态。
例句:
· I don't know where he lives now.(一般现在时)
· I don't know where he went yesterday.(一般过去时)
· I don't know where he will go tomorrow.(一般将来时)
2. 主句为过去时
从句使用相应的过去时态。
例句:
· He asked me what I was doing.(现在进行时 → 过去进行时)
· She wondered why he had left early.(现在完成时 → 过去完成时,或一般过去时 → 过去完成时)
· He didn't know when she would come back.(一般将来时 → 过去将来时)
3. 客观真理
即使主句为过去时,从句仍用一般现在时。
例句:The teacher asked the students why the earth goes around the sun.(地球绕太阳转是客观真理)
(五)疑问词引导的宾语从句的简化
当主句的主语与宾语从句的主语一致时,疑问词引导的宾语从句可以简化为“疑问词 + 不定式”结构。这种简化使句子更加简洁。
1. 简化规则
原句:主句 + 疑问词 + 主语 + should/can/will + 动词原形 + 其他
简化后:主句 + 疑问词 + to + 动词原形 + 其他
2. 常见简化
例句:
· I don't know what I should do. → I don't know what to do.
· She wondered which dress she should choose. → She wondered which dress to choose.
· He didn't know where he could go. → He didn't know where to go.
· Can you tell me how I can get to the station? → Can you tell me how to get to the station?
· She asked when she should leave. → She asked when to leave.
· I forgot whether I should turn left or right. → I forgot whether to turn left or right.
3. 简化时的注意事项
· 简化后的结构中,疑问词仍然保留。
· 不定式的逻辑主语就是主句的主语(或宾语,取决于原从句主语)。
· 这种简化通常用于表示“应该做某事”或“能够做某事”的语境。
· 注意:简化时要用whether,不能用if。例如:I don't know whether to go.(√)I don't know if to go.(×)
(六)疑问词引导的宾语从句的常见句型
1. 与tell,ask,show等动词连用
这些动词常接疑问词引导的宾语从句,表示“告诉、询问、展示”具体信息。
例句:
· Please tell me what your name is.
· He asked me where I lived.
· Can you show me how this machine works?
2. 与know,understand,remember,forget等动词连用
这些动词表示认知状态,常接疑问词引导的宾语从句。
例句:
· I don't know why he is angry.
· Do you remember when we first met?
· He forgot where he had put the key.
3. 与wonder,want to know等动词连用
这些动词表达“想知道”的含义。
例句:
· I wonder what he is doing now.
· She wants to know how she can improve her English.
4. 与depend on,be interested in等短语连用
疑问词引导的宾语从句也常作介词的宾语。
例句:
· The price depends on which size you choose.
· I'm interested in how you made this.
(七)疑问词引导的宾语从句的特殊注意事项
1. 省略疑问词的情况
在口语中,某些情况下疑问词可以省略,但不推荐在书面语中省略。
2. what与which的区别
what不表示选择范围,which表示在一定范围内的选择。
例句:
· I don't know what book he wants.(不知道他想要什么书,没有范围)
· I don't know which book he wants from these two.(不知道他想要这两本中的哪一本,有范围)
3. how单独使用时与how + 形容词/副词的区别
· how单独使用:询问方式。例句:Tell me how you did it.
· how + 形容词/副词:询问程度。例句:Tell me how tall he is.(他有多高)
4. why引导的宾语从句与because连用的错误
回答why引导的从句时,用because引导原因状语从句。但注意不要混淆。
5. 疑问词+ever结构的含义
whatever,whoever,whichever等词引导的宾语从句,表达的是“无论……”的含义,比普通的疑问词语气更强。
例句:
· You can eat whatever you want.(你可以吃你想吃的任何东西。)
· I will support whoever you choose.(无论你选择谁,我都会支持。)

三、将下列句子合并为宾语从句
1. 答案:Can you tell me where she lives?
解析:特殊疑问句改为宾语从句,用原疑问词where引导,从句改为陈述句语序(she lives,而非does she live)。
2. 答案:Do you know why he was late?

3. 答案:Could you tell me what time the train leaves?

5. 答案:I wonder which dress she likes.

8. 答案:I want to know whose phone this is.
解析:whose引导宾语从句,从句改为陈述句语序(this is,而非is this)。whose修饰phone。
9. 答案:Could you tell me how far it is from here to the airport?
解析:how far引导宾语从句,询问距离,从句保持陈述句语序。
10. 答案:I don't know how long he will stay in Beijing.
解析:how long引导宾语从句,询问时间长度,从句改为陈述句语序(he will stay,而非will he stay)。
四、改错
1. 答案:Could you tell me where the library is?
解析:宾语从句必须使用陈述句语序,将is放在library之后。错误地将be动词提到了主语之前。
2. 答案:I don't know what he wants.
解析:宾语从句必须使用陈述句语序,将does he want改为he wants。what在从句中作wants的宾语,语序应为“what + 主语 + 谓语”。
3. 答案:She asked me why I was sad.
解析:that和why不能同时使用。why已经引导宾语从句,不需要再加that。
4. 答案:Can you tell me how I can get to the station?
解析:宾语从句必须使用陈述句语序,将can I get改为I can get。
5. 答案:I wonder why he is so happy today.

6. 答案:He asked me what my favorite color was.
解析:宾语从句必须使用陈述句语序,将what was my favorite color改为what my favorite color was。what在从句中作表语。
7. 答案:Do you know when the movie starts?
解析:宾语从句必须使用陈述句语序,将does the movie start改为the movie starts。
8. 答案:I don't know which one he is going to choose.
解析:宾语从句必须使用陈述句语序,将is he going改为he is going。
9. 答案:She wondered what was the matter with him.
解析:此句实际上是对的!what was the matter with him是固定表达,其中what作主语,was是谓语,the matter是表语,语序本身是陈述句语序。所以无需修改。原句中what was the matter with him是正确的,而what the matter was with him反而是错误的。
10. 答案:Can you tell me how many students there are in your class?
解析:there be句型中,there作主语,are是谓语,students是表语。在宾语从句中保持there are的语序不变,不应改为are there。
五、句型转换
1. 答案:I don't know what to do next.
解析:当主句主语与从句主语一致时,宾语从句可简化为“疑问词 + 不定式”。what I should do简化为what to do。
2. 答案:She wondered which way to take.
解析:which way she should take中的主语she与主句主语一致,可简化为which way to take。
3. 答案:He didn't know where to find his keys.
解析:where he could find his keys简化为where to find his keys。
4. 答案:Can you tell me how to use this camera?
解析:how I can use this camera简化为how to use this camera。
5. 答案:She asked me when to leave.
解析:when she should leave简化为when to leave。
6. 答案:I forgot whether to turn left or right.

7. 答案:He told me how to solve the problem.
解析:how I could solve the problem简化为how to solve the problem。
8. 答案:I don't know where to go.
解析:where I should go简化为where to go。
9. 答案:She taught me what to do.
解析:what I should do简化为what to do。
10. 答案:He wondered how to improve his grades.
解析:how he could improve his grades简化为how to improve his grades。
六、翻译句子
1. 答案:Can you tell me where the bank is?
解析:特殊疑问句“银行在哪里”改为宾语从句,用where引导,陈述句语序the bank is。
2. 答案:I don't know why he is so sad.
解析:“为什么”用why引导,从句用陈述句语序he is so sad。
3. 答案:Do you know when he will come back?
解析:“什么时候”用when引导,将来时用will come back。
4. 答案:I want to know what color she likes.
解析:“什么颜色”用what color引导,从句用陈述句语序she likes。
5. 答案:Please tell me how to get to the railway station.
解析:宾语从句简化为“疑问词 + 不定式”结构。how to get to比how I can get to更简洁。
6. 答案:He asked me who broke the window.
