高中英語從句語法總復習

1、常考知識在復合句中修飾名詞或代詞的從句叫定語從句。被修飾的名詞或代詞叫先行詞。通過從句的意思判斷先行詞。引導定語從句的關(guān)系代詞有who，, whom whose, which , that等和關(guān)系副詞 where, when, why等。一、非限制性定語從句記：有逗號的從句，連接詞一定不用 that 。典型例題They will fly to Washington,they plan to stay for two or three days.A.whereB.thereC.whichD.when二、關(guān)系代詞 who, whom whose引導的定語從句這類定語從句中，who在從句中用作主語，

2、whom從句中用彳賓語，whose從句中用作定語注意：Whose既可代表人，也可代表物eg： Do you see the house whose windows are all broken?三、關(guān)系代詞that 和 which 引導的定語從句1、只能用which 的情況（ 1）介詞 +which（ 2）非限制性定語從句2、只能用that 的情況（1）先行詞為不定代詞（all , nothing , much等）（ 2）兩個the ：先行詞為序數(shù)詞和最高級（ 3）人和物同時做先行詞時（ 4）先行詞被the only ， the very 修飾時3、“介詞+which/whom”中介詞的選擇關(guān)

3、系代詞前的介詞使用時根據(jù)與名詞前面的動詞搭配關(guān)系和介詞的搭配關(guān)系及句子結(jié)構(gòu)上的需要而定。eg: We'll never forget the day on which we went camping.四、關(guān)系副詞 when, where , why引導的定語從句1、when, where, why吮詞+which ,有時為表達清楚，還可在關(guān)系副詞where、when前加介詞from, to。Reason Why= reason for which2、關(guān)系副詞和關(guān)系代詞的比較記：從句的句子是完整的連接詞一定用關(guān)系副詞3、高考對關(guān)系副詞where 的考查高考中對where的考查趨于復雜，先

4、行詞由“明顯的地點”轉(zhuǎn)為“地點的模糊化" 。Where不能只理解為表地點，當先行詞表示某人 / 物的處境（situation ） ，或某事所發(fā)展的階段，或表達某事的某個方面（ part ，point ）時都可用where 這個關(guān)系副詞。例詞： Place 地點 Case 案例 Situation 形勢 Point 點 Top 頂點 Position 地位 Stage 階段 Occasion 場合 Aspect 方面五、關(guān)系代詞as， which 的區(qū)別As主要用于 as as; the same as；such as等結(jié)構(gòu)中。譯為"正如"。as 引導非限制性的定語

5、從句，修飾前面整個句子，而which 均可。eg： The meeting,which was held in the park,was a success.eg： The meeting was a success,as was expected.典型例題（ 1） My friend showed me round the town, was very kind of him.A. whichB. thatC. where D. it（ 2） The Beatles ， many of you are old enough to remember,came from Liverpool.A.

6、whatB.that C.how D.as六、way的特殊用法The way that/which/ 不填 he explained to us was quite simple.The way that/in which/ 不填 he explained the sentence to us was not difficult to understand.考點剖析命題規(guī)律：（ 1 ）關(guān)系代詞的辨析及關(guān)系副詞的辨析。（ 2）關(guān)系代詞的指代情況（3）定語從句的主謂一致問題。例題：規(guī)律總結(jié)：定語從句一般考連接詞，一般分三步完成。1 、判斷定語從句的先行詞和理解從句意思。2、看從句是否完整，完整一定

7、用關(guān)系副詞。3、不完整的（ 1） * 關(guān)系代詞和關(guān)系副詞的辨析，判斷從句是否完整，完整的連接詞一定用關(guān)系副詞。eg： This is the farm where he works.eg： This is the farm which he visits.*遇至U situation , part , point , place , period 等，般連接詞用where。遇至U time , age, day 等，般連接詞用when。*介詞后一定不加 that ,注意介詞的判斷。介詞 +which/whom （不用who）。關(guān)系副詞=介詞+which（ 2） *非限制性定語從句及有逗號的從句

8、，一定不用that （特別注意先行詞為整個句子時）。*which ， that 的一些特殊用法。* 作賓語的關(guān)系代詞可省略（ 3）定語從句的兩個特殊句型*Is this school we visited that year?Is the school we visited that year?Is this the school we visited that year?名詞性從句常考知識一、名詞性從句的結(jié)構(gòu)和功能總述名詞性從句包括主語從句、賓語從句、表語從句、同位語從句。具有名詞性功能。名詞性從句主要有四種從句結(jié)構(gòu)：以 that 引導的從句；以 whether/if 引導的從句；以特殊疑問

9、詞引導的從句；以 what 或 wh-ever等連接代詞引導的名詞性關(guān)系從句。主語從句賓語從句表語從句同位語從句作及物動詞賓語作介詞賓語that 一般不省略可以省略一般不省略一般不省略一般不省略whether/if （是否）放于句首時只用whether 用 whether/if 均可，但有區(qū)別只用 whether 只 用whether 只用 whether特殊疑問詞注意語序要用陳述語序名詞性關(guān)系從句注意語序要用陳述語序典型例題（ 1） Can you tell me （ 我如何去）get to the railway station?（ 2） These photographs will sh

14、at 引導表語從句時，不可省略。eg: My decision is that all of us are to start at 6 o'clock tomorrow morning.（四）同位語從句連詞 that 引導的同位語從句，在從句中不擔當任何成分，不省略。 應在某些有內(nèi)容的名詞之后，如： fact ，hope， desire ， thought ， suggestion ， idea ， news， problem ， possibility 等。eg： There's a feeling in me that we'll never know what a

15、 UFO is not ever.三、 whether/if （是否）（一）在表語從句和同位語從句中只能用whether 不能用 if ；當主語從句放于句首時，也只能用whether不用 if ；當 it 作形式主語，主語從句放在句末時用whether 或 if 均可。eg： Whether the meeting will be given is still a problem.eg： It is doubtful whether/if he will come here.eg： The problem is whether the meeting will be given.eg： I h

16、ave no idea whether the meeting will be given.（二）在賓語從句中：介詞后只用whether ，不用 if 。eg： I depends on whether you can do the work well.典型例題（ 1） we'll go camping tomorrow depends on the weather.（ 2） I am not surehe will come here or not.（ 3） This decision will have effect on or not he will succeed.四、特殊疑問

21、he wouldn t listen to me.=No matter what I said， he wouldn t listen tome.eg： He would believe whatever I said.另外，whoever， whatever ， whenever， wherever 中， ever 起強調(diào)作用，意為“究竟、到底”。（二）as if/as though , because , why 也可弓 I導表語從句。eg： It looked as if it was going to rain.（三）連詞that 引導的同位語從句和關(guān)系代詞that 引導的定語從句的區(qū)

22、別1、連詞 that 引導同位語從句時，應放在某些具有內(nèi)容的名詞之后，如fact ， hope， desire ， thought 等，對前面的名詞起補充說明的作用。只起引導的作用，在從句中不擔當任何成分，因此that 引導的同位語從句是完整的。2、關(guān)系代詞that 引導定語從句時，在定語從句中擔當成分（主、賓）， that 引導的定語從句時殘缺的。eg： The news that our football team won the match was encouraging.eg： The news that we heardon the radio was not true.并列句和狀語
