冲刺中考英语重点语法之宾语从句-冲刺中考英语必考语法考前突击训练课件PPT
展开What is the Object Clause? (什么是宾语从句)
宾语从句是主从复合句的一种。主从复合句是由一个主句或一个以上的从句构成。主句是复合句的主体,从句仅是主句的一个成份,它从属于主句,不能独立。从句在全句中充当什么成分,就叫什么从句。宾语从句中的从句在全句中做宾语。
I dn’t knw that he likes playing basketball..
由从属连词that引导的宾语从句
由从属连词 whether, if 引导的宾语从句
由连接代词 wh, whm, whse, which,what 和连接副词 where, hw, why, when引导的宾语从句
不同引导词引导的宾语从句
(1)陈述句的引导词用thatthat 在句中无词汇意义,在从句中不能充当成分,在口语当中往往省略。 I hear (that) yu passed the exam.2. He said (that) his father was a singer.3. The teacher tld us (that) the sun rises in the east.
但that引导的宾语从句作except, in, but, besides等少数介词的宾语时that不能省略。如:I knw nthing abut him except that he is frm the suth.除了知道他来自南方以外,我对他一无所知。
由从属连词whether, if引导的宾语从句
(2)一般疑问句的引导词用if/whetherif/ whether “是否”,说明对陈述的事物不明确或不清楚。常用在ask, wnder, can(culd) yu tell me 等后。 I want t knw whether/if he is right.2. I Ask him whether/if he likes me.3. I wnder whether/if we can get there.4. Culd yu tell me whether/if that film is interesting ?
◆只能用whether不能用if的情况1.在介词后面:I’m thinking f whether we shuld g fishing.We are wrried abut whether it will rain tmrrw.2.在动词不定式前:They asked me whether t g skating.
3.当与r nt连用,或提出两种选择时:I dn’t knw whether he’s free r nt.Mary asked whether I was ding my hmewrk r nt.Tell me whether yu’d like t g shpping r tidy the rm.4.宾语从句提前时:Whether this is true r nt, I can’t say.
由连接代词和连接副词引导的宾语从句
(3)由连接代词和连接副词引导的宾语从句①连接代词wh,whm,whse,what,which,whever,whatever在句中有词义,充当从句中的主语、宾语、表语、定语。如:I wnder what he’s writing t me. (宾语)我想知道他正在写什么给我。He can’t decide which sweater he shuld buy. (定语)他不确定他该买哪件毛衣。
②连接副词where,when,hw,why在句中有词义,并且充当从句中的状语。如:I’ll tell yu why I asked yu t cme. (原因状语)我会告诉你我为什么要你来。Culd yu tell me where Tm has gne? (地点状语)你能告诉我汤姆去哪里了吗?I want t knw when yu can finish the wrk. (时间状语)我想知道你什么时候能够完成这项工作。

宾语从句的语序,即从句部分应为陈述句语序。尤其要注意引导词:if或whether引导的宾语从句及以连接代词或连接副词引导的宾语从句。
①陈述句变为宾语从句,语序不变,即仍用陈述语序。如:He is an hnest by. The teacher said.→The teacher said(that)he was an hnest by.②一般疑问句和特殊疑问句变为宾语从句,语序变为陈述语序。如:Des he wrk hard?I wnder.→I wnder whether/if he wrks hard.
When did he leave?I dn’t knw. →I dn’t knw when he left.(3)What’s wrng with…?和What’s the matter?在宾语从句中语序不变。如:I want t knw what’s wrng with yu. 我想知道你怎么了。Culd yu tell me what’s the matter?可以告诉我怎么了吗?
