宾语从句
【知识要点】
1.宾语从句在句中作及物动词或介词的宾语,从句放在主句之后,前后不用逗号分开。
2.引导宾语从句的词有:
连词that(在口语中that常可省略),if, whether,如:
He knows that Jim will work hard.
连接代词who, whom, which等,如:
Do you know who (whom) they are waiting for?
连接副词when, where, how, why等,如:Could you tell me how we can get to the station?
3.whether和if都有“是否”的意思,一般情况下两者可以换用,但在介词之后,
不定式之前,与or not连用,在句首或在引导表语从句,同位语从句时,只能用whether,如:I want to know if/whether the news is true. He doesn't know whether to stay or not?
4.宾语从句要用陈述句语序。
5.宾语从句一定要注意时态呼应,即:当主句谓语动词是过去式时,从句中谓语动
词也要用过去范畴的时态,但若从句陈述的是真理或客观规律,其谓语的时态仍用一般现在时,如:
He asked who could answer the question.
My father told me that the earth goes around the sun.
6.一个宾语从句只能用一个连词。
7.当主句谓语动词是think, believe等动词时,宾语从句的否定意义要放到主句中。另外,当主句主语为第一人称时,后面若接附加疑问句,那么附加疑问句的主语、谓语应与从句中的主谓语保持一致。如:
I don't think he looks like his father, does he?
8.直接引语和间接引语也是宾语从句,直接引语是引述别人的原话,放在引号内,
不用连词联接;间接引语是用自己的话转述别人的话,通常用连接词与主句联接。
(1)陈述句变为以that引导的宾语从句,如:
He said,“I'm happy.”[FY()[FY]]He said that he was happy.
(2)一般疑问句变为if(whether)引导的宾语从句,如:
He asked me,“Does his father know Mr Green?”
---He asked me if his father knew Mr Green.
(3)特殊疑问句变为由who, what, where, how等疑问词(连接代词或连接副词)引导的宾语从句,如:
He asked me,“Where is Mr Wang?”
---He asked me where Mr Wang was.
注意上述例句中连词、时态、语序等变化。
定语从句
定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个名次性成分,定语从句分为限定性和非限定性从句两种。
一、 限定性定语从句
1. that即可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略
4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
5. where是关系副词,用来表示地点的定语从句
6. when引导定语从句表示时间
〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
By the time you arrive in London, we will have stayed there for two weeks.
I still remember the first time I met her.
Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.
7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格
8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导
二、非限定性定语从句:非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立
1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which
Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。
I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反。
We arrived the day that(on which) they left. 刚好我们到的那天他们走了。
3. 有时as也可用作关系代词
4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物.
