三、知識(shí)講解
知識(shí)點(diǎn)1：定語從句的概念和先行詞
1. 【考查點(diǎn)】在復(fù)合句中，修飾某一名詞或代詞的從句叫定語從句。(而在一個(gè)句子中充當(dāng)整個(gè)句子的賓語的句子叫做賓語從句)
如：I love this English teacher whose eyes are blue. (定語從句)
我愛眼睛是藍(lán)色的這位英語老師
I don’t know (賓語從句)
我不知道你怎樣才能到達(dá)那個(gè)公園。
2. 【考查點(diǎn)】被定語從句修飾的名詞或代詞叫先行詞。
如：A friend is someone who says, "What! You too? I thought I was the only one!”
A Wechat (微信) is an invention which can help people talk to friends, share photos, ideas and feeling freely.
知識(shí)點(diǎn)2：定語的關(guān)系詞~關(guān)系代詞
1.【考查點(diǎn)】既能指物也能指人的關(guān)系代詞 that，whose。
如： ① I like this person that has 3 story books. (先行詞是人person)
�、谙刃性~是物book)
①(先行詞是teacher)
�、谙刃性~是dog)
2、【考查點(diǎn)】只能用來指代人的關(guān)系詞who, whom.
如：Is he the man who wants to see you?
He is the man whom/ that I saw yesterday.
3、【考查點(diǎn)】只能指代物的關(guān)系詞which。
如：A prosperity which had never been seen before appears in the countryside.
4、【考查點(diǎn)】關(guān)系詞在句子中充當(dāng)?shù)某煞帧?/p>
如：1、(who/that在從句中作主語)
他就是你想見的人嗎?
2、他就是我昨天見的那個(gè)人。(whom/that在從句中作賓語)
3、作賓語) which / that在句中(
農(nóng)村出現(xiàn)了前所未有的繁榮。
4、((只用作定語)
那人車壞了，大家都跑過去幫忙。
(注：當(dāng)上題先行詞指物時(shí)它還可以同of which互換)
如：Please pass me the book whose (of which) cover is green.
請(qǐng)遞給我那本綠皮的書
知識(shí)點(diǎn)3：關(guān)系副詞引導(dǎo)的定語從句
關(guān)系副詞when, where, why可代替的先行詞是時(shí)間、地點(diǎn)或理由的名詞，在從句中作狀語。
【考查點(diǎn)】關(guān)系副詞when, where, why的含義相當(dāng)于"介詞+ which"結(jié)構(gòu)，因此常常和"介詞+ which"結(jié)構(gòu)交替使用。
如： There are occasions when (on which) one must yield.
任何人都有不得不屈服的時(shí)候。
Beijing is the place where (in which) I was born.
北京是我的出生地。
Is this the reason why (for which) he refused our offer?
這就是他拒絕我們幫助他的理由嗎?
知識(shí)點(diǎn)4：關(guān)系詞的選擇取決于從句中的'謂語動(dòng)詞
1.【考查點(diǎn)】 用關(guān)系代詞，還是關(guān)系副詞完全取決于從句中的謂語動(dòng)詞。及物動(dòng)詞后面無賓語，就必須要求用關(guān)系代詞;而不及物動(dòng)詞則要求用關(guān)系副詞。
如： This is the mountain village where I stayed last year.
四、例題精析
【例題1】

A. running; that B. run; who C. running; who D. run; that

【題干】Is this research center ________ you visited the modern equipment last year?
A. where B. that C. the one that D. the one where
【答案】：D
【解析】：將疑問句改為陳述句：this research center is…顯然缺少先行詞，必須加上代詞the one來作先行詞，又因定語從句不缺主語或賓語，所以用關(guān)系副詞where。假若在this后加the，就選where，請(qǐng)想想這是為什么。

A. that have been shown this year B. that have shown
C. that has been shown this year D. that you talked
【答案】A.
【解析】本句話的先行詞應(yīng)該是films,因此，關(guān)系代詞that是負(fù)數(shù)概念，其謂語動(dòng)詞應(yīng)用復(fù)述的被動(dòng)語態(tài)have been shown。如果句中的one前面使用了定冠詞the，則the one應(yīng)該視為先行詞。

課程小結(jié)
本節(jié)課主要圍繞定語從句的�？键c(diǎn)展開，即：定語從句的概念，定語從句的關(guān)系詞，定語從句的先行詞等。需要重點(diǎn)掌握的是定語從句的先行詞和定語從句的關(guān)系詞。此外，在初中階段也會(huì)經(jīng)常接觸到定語從句關(guān)系代詞和關(guān)系副詞的選擇，因此，這個(gè)考點(diǎn)也需要重點(diǎn)掌握。
近年中考對(duì)語法點(diǎn)的考查往往是與語境想結(jié)合，因此，同學(xué)在做題時(shí)要結(jié)合語境來分析題目，靈活地運(yùn)用語法知識(shí)。
