高一上課定語從句二

1、定語從句（二）關(guān)系代詞as和關(guān)系副詞一、as作關(guān)系代詞的用法。1. fve never heard such stories as he tells.我從未聽過他講的這類故事。2. we hope to get the same tool as he is using.3. have you bought the same book as i referred to yesterday?你有沒有買我昨天說的那本書??？as在它引導(dǎo)的定語從句邙艮制性或非限制性）屮可以充當(dāng)主語，賓語和表語； 在這種用法中它經(jīng)常'和such, so, the same等詞搭配使用；且當(dāng)先行詞中有such, s

2、o, the same等詞修飾時(shí),關(guān)系代詞通常必須用as。such +名詞+as.像一樣的，像之類的the same +名詞+ as.和同樣的1. they were satisfied with this decision, as was agreed.他們對(duì)這個(gè)決定都滿意，這事已經(jīng)經(jīng)過他們同意了。（as在定語從句中作主語，其先行詞是this decision）2.1 never heard such stories as he tells.我從未聽過他講的這類故事。（as在定語從句中作賓語，先行詞是such stories.）3.have you bought the same book

3、as i referred to yesterday?你有沒有買我昨天說的那本書?。浚╝s在定語從句中作賓語，先行詞是book）二、as和which的區(qū)別1. as和which都可引導(dǎo)非限制性定語從句。as引導(dǎo)的非限制性定語從句，既可在主句 前，乂可在主句后，有時(shí)還可以插入主句中，而which引導(dǎo)的非限制性定語從句只能 置于主句之后。相同的是兩者都可以替代主句的整個(gè)內(nèi)容，而不是主句的某一個(gè)詞。女口：2. 當(dāng)非限制性定語從句放在主句前面時(shí)，只能用as.as is known to everybody, the moon travels round the earth once every mon

4、th.=the moon travels round the earth once every month, as/which is known to everybody.it is known to everybody that the moon travels round the earth once every month.what is known to everybody is that the moon travels round the earth once every month.另外，as多用于下列習(xí)慣用語中，which不可以。as anybody can see正如人人都能

5、看到的那樣as is well-known =as is known to all 眾所周知as we had expected正如我們所預(yù)料的那樣as often happens正如經(jīng)常發(fā)生的那樣as has been said before 如上所述as is mentioned above正如上面提到的3. 當(dāng)定語從句放在主句后面時(shí)，也并不是as就永遠(yuǎn)等于which(1) 當(dāng)非限制性定語從句是否定或表示否定時(shí)只能用whichohe came here very late, which was unexpected (not expected).(2) 當(dāng)as在從句中作主語時(shí)，后面常接動(dòng)詞

6、的被動(dòng)語態(tài)。女u be known, be said, be reported, be announced 等she has been absent again, as is expected.(被動(dòng))tom has made progress, which makes me very happy.(主動(dòng))(3) as 常用在 as (it) seems likely, as (it) often happens, as (it) was printed out, as (it) was said earlier, as i remember (it), as i understand (it

7、), as (it) appears 等纟吉木勾中。定語從句關(guān)系副詞定語從句中的關(guān)系副詞有三個(gè)：when, where和why,它們?cè)诙ㄕZ從句屮分別作時(shí)間、 地點(diǎn)和原因狀語。其句法結(jié)構(gòu)如下：1 表時(shí)間的名詞+ when +定語從句when指時(shí)間，在定語從句屮作時(shí)間狀語。例句：i still remember the day when i first came to beijing.fll never forget the day when i joined the army.2. 表地點(diǎn)的名詞+ where +定語從句where指地點(diǎn)，在定語從句屮作地點(diǎn)狀語。例句：the factory wh

8、ere his father works is in the west of the city.this is the house where i lived two years ago.3. 表原因的名詞reason + why +定語從句(why只用于reason之后的限制性定語從句 中，在定語從句中作原因狀語。)例句：that is the reason why i did the job.(在現(xiàn)代英語中why可以省略)關(guān)系副詞在定語從句中的用法看似簡單，以下注意點(diǎn)不可忽視:1) “when”、"where"和“why”的運(yùn)用取就于表時(shí)間的名詞、表地點(diǎn)的名詞和表原 因

9、的名詞reason在定語從句中所作的成分，比較下而的幾組句子：*1 will never forget the day when i first met you in the park.*1 will never forget the days which/that we spent together.*this is the hospital where my mother works.*this is the hospital which/that we visited the day before yesterday.*the reason why he did not go to sc

10、hool is that he was ill.*this is the reason which/that he gave his boss in the office .注意：確立關(guān)系代詞which/that或關(guān)系副詞when/where/why的方法：看定語從句中是否缺 少主語或賓語，如果缺少用which/ that；如果不缺主語或賓語用when/where/ why.2) "when”、uwhere”和“why”都可以替換成"介詞+ which”,介詞的選用取就 于先行詞和定語從句中的動(dòng)詞。例如：do you still remember the day on wh

11、ich we first met in nantong? (on which二when)this is the room in which we lived last year. (in which=where)do you know the reason for which he refused to go to mary's birthday party, (for which=why)有吋定語從句中介詞短語和動(dòng)詞有意義緊密的修飾關(guān)系，尤其在非限制性定語從句 中，常使用“介詞+ which”結(jié)構(gòu)，而不使用關(guān)系副詞。例如：my mother works in a factory, i

12、n front of which there is a small river.at night the soldiers got to a small hill, at the foot of which stood a farmhouse.練習(xí)()1. it is very useful to master a foreign language, has been said before.a. which b. wherec. asd. when()2everyone hoped, mary has won the first prize.a. whichb. wherec. asd wh
