【正文】 明確修飾關(guān)系，應(yīng)當(dāng)用who(m)。如：A new master will came tomorrow who will teach you ’s only one student in the school who/whom I wanted to was the only person in my office who was invited.(5)兩個(gè)定語(yǔ)從句同時(shí)修飾一個(gè)指人的先行詞，第二個(gè)定語(yǔ)從句常用who(m)來(lái)引導(dǎo)，如：She is the only girl I know who can play the ，當(dāng)先行詞指人時(shí)，在下列情況中，一般用關(guān)系詞that:(1)當(dāng)主句是以who或which開(kāi)頭的特殊疑問(wèn)句時(shí)。如： Who is the man that is reading the newspaper over there? Which of us that knows anything does not know this?(2)當(dāng)先行詞被形容詞最高級(jí)或序數(shù)詞所修飾時(shí)。如： He is the greatest man that has ever lived.(3)當(dāng)先行詞被the only, the very, the last等詞所修飾時(shí)。如： She is the only person that understands same所修飾時(shí)，關(guān)系詞既可以用as，也可以用that。在表示具體事物時(shí)，有時(shí)兩者有一定的區(qū)別。一般說(shuō)來(lái)，表示同一種類(lèi)多用as，表示同一事物多用that。如：This is the same instrument that I used 。This is the same instrument as I used 。在抽象概念上，同種類(lèi)和同一事物是沒(méi)有絕對(duì)區(qū)別的，所以?xún)蓚€(gè)詞可換用： I have the same opinion as / that you ：（1）使用as時(shí)，它引導(dǎo)的定語(yǔ)從句中的動(dòng)詞可以省略，但使用that時(shí)，定語(yǔ)從句中 的動(dòng)詞不可省略。如： Women received the same pay as received the same pay that men received.(2)在“the same?that”結(jié)構(gòu)中，that只是用來(lái)加強(qiáng)語(yǔ)氣，強(qiáng)調(diào)“相同”。第5/6頁(yè)that可以省去而不改變句子原意，甚至連名詞前的same也可以省去。如： This is the same instrument that I used yesterday.= This is the same instrument I used yesterday.= This is the instrument I used “the same?as”結(jié)構(gòu)中，same和as都不能省略。(3)當(dāng)“the same?that”結(jié)構(gòu)中的that作為關(guān)系副詞用時(shí)，不可以直接與as互換。如：He lives in the same building that I live.= He lives in the same building as / that I live we meet at the same place that we last met? = Shall we meet at the same place that / as we last met at? , so, as時(shí)，關(guān)系詞應(yīng)當(dāng)用as。如： A wise man seldom talks about such things as he doesn’t spoke in such easy English as everybody could this time of the day, all buses and trolleys have to carry as many passengers as they is so easy a book as every schoolboy can ’s discuss such things as we can talk of ：This book is written in such easy English as beginners can understand.（定語(yǔ)從句）This book is written in such easy English that beginners can understand it.（結(jié)果狀語(yǔ)從句），也可放在主句之后，用來(lái)修飾整個(gè)句子。通常用下列句型：as is known to all,as is said,as is reported, as is announced,as we all know,as I expect等。Eg：As I expected,he got the first place again in this midterm ，他在這次期中考試中又獲得了第一名。第五篇：定語(yǔ)從句講解定語(yǔ)從句講解一、定語(yǔ)從句的概念在復(fù)合句中，修飾某一名詞或代詞的從句叫定語(yǔ)從句。被修飾的名詞或代詞叫先行詞，定語(yǔ)從句一般放在先行詞的后面。如：He is the boywho often goes to school 關(guān)系詞定語(yǔ)從句二、定語(yǔ)從句的關(guān)系詞引導(dǎo)定語(yǔ)從句的關(guān)系詞有關(guān)系代詞和關(guān)系副詞，常見(jiàn)的關(guān)系代詞包括that，which，who（賓格whom，所有格whose）等，關(guān)系副詞包括where，when，why等。關(guān)系代詞和關(guān)系副詞放在先行詞及定語(yǔ)從句之間起連接作用，同時(shí)又作定語(yǔ)從句的重要成分。三、定語(yǔ)從句的分類(lèi)根據(jù)定語(yǔ)從句與先行詞的關(guān)系，定語(yǔ)從句可分為限制性定語(yǔ)從句及非限制性定語(yǔ)從句。限制性定語(yǔ)從句緊跟先行詞，主句與從句不用逗號(hào)分開(kāi)，從句不可省去，非限制性定語(yǔ)從句主句與從句之間有逗號(hào)分開(kāi)，起補(bǔ)充說(shuō)明作用，如省去，意思仍完整。四、關(guān)系代詞的用法 既可以用于指人，也可以用于指物。在從句中作主語(yǔ)或賓語(yǔ)，作主語(yǔ)時(shí)不可省略，作賓語(yǔ)可省略。例如：Mary likes music that is quiet and 。（that作主語(yǔ)）The coat（that）I put on the desk is 。（that作賓語(yǔ)），在句中作主語(yǔ)或賓語(yǔ)，作主語(yǔ)不可省略，作賓語(yǔ)可省略。例如：The building which stands near the train station is a 。（作主語(yǔ)）The film（which）we saw last night was 。（作賓語(yǔ)），whom用于指人，who 用作主語(yǔ)，whom用作賓語(yǔ)。在口語(yǔ)中，有時(shí)可用who代替whom，也可省略。例如：The girl who often helps me with my English is from 。（作主語(yǔ)）Who is the teacher（whom）Li Ming is talking to？正在與李明談話(huà)的老師是誰(shuí)？（作賓語(yǔ)）注意：（1）當(dāng)定語(yǔ)從句中含有介詞，介詞放在句末時(shí)，who，that，which可省略，但介詞在關(guān)系代詞前時(shí)，只能用“介詞+which/whom”結(jié)構(gòu)。例如：This is the house in which we lived last 。Please tell me from whom you borrowed the English 。（2）含有介詞的固定動(dòng)詞詞組中，介詞不可前置，只能放在原來(lái)的位置上。例如：This is the person whom you are looking 。（3）that 作介詞的賓語(yǔ)時(shí)，介詞不能放它的前面，只能放在從句中動(dòng)詞的后面。例如：The city that she lives in is very far 。（4）關(guān)系詞只能用that的情況：，或本身是序數(shù)詞、基數(shù)詞、形容詞最高級(jí)時(shí)，只能用that，：He was the first person that passed the 。，any，much，many，everything，anything，none，the one等不定代詞時(shí)，只能用that，：Is there anything that you want to buy in the shop？你在商店里有什么東西要買(mǎi)嗎？ only，the very，the same，the last，little，few 等詞修飾時(shí)，只能用that，：This is the same bike that I 。，只能用that，：I can remember well the persons and some pictures that I saw in the 。，為避免重復(fù)，：Who is the girl that is crying？ 正在哭泣的那個(gè)女孩是誰(shuí)？ be 結(jié)構(gòu)，修飾主語(yǔ)的定語(yǔ)從句用that，：There is a book on the desk that belongs to 。（5）關(guān)系詞只能用which，而不用that 的情況：，those時(shí)，用which，：What’s that which is under the desk？ 在桌子底下的那些東西是什么？，一般用which，：This is the room in which he 。，用which，：Tom came back，which made us ，這使我們很高興。五、關(guān)系副詞的用法（1）when指時(shí)間，其先行詞表示時(shí)間，在句中作時(shí)間狀語(yǔ)。例如：This was the time when he 。（2）where指地點(diǎn)，其先行詞表示地點(diǎn)，在句中作地點(diǎn)狀語(yǔ)。例如：This is place where he 。（3）why 指原因，其先行詞是原因，起原因狀語(yǔ)作用。例如：Nobody knows the reason why he is often late for 。
