试一试,你能将下列句子改为宾语从句吗?
1、She is a careful girl.
The teacher said a careful girl.

【教师指导】
一,所谓宾语从句就是句子的宾语一般由名词、代词、 动名词或动词不定式充当,当一个句子充当宾语时,我们把这个句子叫做宾语从句。
宾语从句的三要点:1、引导词2、从句语序3、从句的时态
二、宾语从句的连接词或引导词
1.连词that,只起连接作用,在从句中不作句子成分,也无词汇意义,在口语中常被省略。
eg. I am afraid(that)you are right.
2.连词if 、whether,它们起连接作用,在从句中不作句子成分,作“是否”解,在口语中多用if。
eg. Tom don't know if/whether his grandpa liked the present.
He asked me whether or not I was coming.
一般情况下,if 和whether可以互换,但以下3种情况只能用whether:
①在不定式前:Whether to go there or not hasn't been decided.
②在介词前:It depends on(依靠) whether it is going to rain.
③与or not连用:They are talking about whether to go there or not.
④宾语从句放在句首表示强调时,只能用whether 。
Whether they can finish the work on time is still a problem .
3.连接代词who, whom, whose, what, which,连接副词when, where, why, how, 它们起连接作用,作句子成分,各有自己的意义。
eg.1. He asked ______________________________. (谁能回答这个问题)
2. Do you know__________________________. (他们在等谁)
3. Please tell me ____________________________. (我们什么时候开会)
4. Can you tell me ______________. (他在哪儿)
5. Could you tell me ____________________________. (我该怎么去站)
6. Would you tell me ____________________.(为什么火车迟到了)
三、宾语从句的语序
宾语从句的语序是陈述语序,即“连接词+主语+谓语+其它成分”。特别强调:它的主语和谓语的语序是陈述语序,而不是疑问句的倒装结构。
Can you tell me who(m) do we have to see?(╳)
Can you tell me who(m) we have to see?( √)
The teacher asked the students what they were doing.(思考: what在从句中的成分)
陈述句变为宾语从句时,要注意人称和时态的变化,语序不变。 eg. She said, “I will leave a message on the desk.” → She said she would leave a message on the desk.
四、宾语从句的时态呼应
宾语从句中谓语动词的时态,常常受到主句谓语时态的制约,此为时态呼应。如果主句谓语是一般现在时或将来时,从句谓语的时态不受限制;如果主句谓语的时态是一般过去时,从句一般要随着改为相应的过去时态(一般过去时、过去进行时、过去将来时、过去完成时)。
eg. I thought (that) you are free today. (╳)
I thought (that) you would be free today. ( √)
【注意】当宾语从句叙述的是客观真理时,不管主句谓语的时态如何,从句都用一般现在时。
eg. The teacher told us (that) the earth moves around the sun.
五。其他需要说明的问题
1.标点由主句决定,如主句是陈述句、祈使句,则用句号;是疑问句则用问号。
eg. I heard she had been to the Great Wall. Can you tell me which bus I should take?
2、宾语从句的特殊情形
在“Do you think /believe/suppose----?等”结构中,宾语从句如果是由疑问词引导的,则要用“疑问词+ do you think/believe/suppose +正常语序?”
如:What has happened to him? Do you think? What do you think has happened to him?
3.宾语从句的否定形式
在think, believe等动词后面的宾语从句,如果从句的谓语动词表示否定意义,一般要将否定词not移到主句的谓语动词上面去,即通过否定主句的谓语动词来否定从句的(意义)谓语动词。此时变反意疑问句时仍将宾语从句视为否定,反意疑问部分用肯定形式。如:
1、I don't think he will come.
2、I don't think he will come, will he?
3、I think he will come, won't he?
4. 句式的转变
1、当主句的谓语动词是hope, decide, wish, agree等,其后接宾语从句,并且从句主语与主句主语一致时,可以简化成动词不定式结构。
如:Wei Hua hopes that she will be back soon.
Wei Hua hopes to be back soon.
2、当know, learn, remember, forget等动词其后接宾语从句,并且从句主语与主句主语一致时,可以简化成“疑问词+不定式”结构。
如:I don't know what I should say. I don't know what to say.
3、当tell,learn,show,teach等动词其后接宾语从句,并且从句主语与主句的间接宾语一致时,可以简化成“疑问词+不定式”结构。
如:Could you tell me how I can get there?(句子中的 me 和I指的是同一个人)可以改写为:Could you tell me how to get there?
【课堂同步检测】
【复习小结】
1、变宾语从句的四个要素:引导词、语序、时态和标点符号
2、牢记宾语从句中的陈述句语序。
3、注意主句与从句时态的一致性(即:当主句是过去式时,从句要用过去范畴的某种时态,客观真理或自然现象除外)
