【正文】 性定語從句。如：He is the boywho often goes to school 關系詞定語從句二、定語從句的關系詞引導定語從句的關系詞有關系代詞和關系副詞，常見的關系代詞包括that，which，who（賓格whom，所有格whose）等，關系副詞包括where，when，why等。第三篇：定語從句講解定語從句講解一、定語從句的概念在復合句中，修飾某一名詞或代詞的從句叫定語從句。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。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，關系詞應當用as。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。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只是用來加強語氣，強調(diào)“相同”。This is the same instrument as I used 。一般說來，表示同一種類多用as，表示同一事物多用that。如： She is the only person that understands same所修飾時，關系詞既可以用as，也可以用that。如： Who is the man that is reading the newspaper over there? Which of us that knows anything does not know this?(2)當先行詞被形容詞最高級或序數(shù)詞所修飾時。如：Do you know the writer in blue with thick glasses who is speaking at the meeting?(4)在分隔式定語從句中，若先行詞指人，為了明確修飾關系，應當用who(m)。如： He who wants to catch fish just not mind getting who are against the proposal put up your ：在固定結(jié)構(gòu)的諺語或習語中，可用he that?。但在下列情況中，用who(m)，而不用that：(1)當先行詞是one, ones, any, few, anyone, anybody, someone, somebody, everyone, everybody等詞時。This is the room in which my father lived last 。如： Which is the car that killed the boy? Who is the person that is making this lecture? ：①引導非限制性定語從句； ②代表整個主句的意思； ③介詞+關系代詞。如： This is the very book that I want to find.(6)當先行詞為指人和指物的兩個并列名詞詞組時。如：We heard clearly every word that he said.(3)當先行詞是序數(shù)詞或被序數(shù)詞所修飾時。如：Do you know the boy to whom she was talking?第3/6頁Do you know the boy(that)she was talking to? The pencil(which/that)he was writing with suddenly ． 在限制性定語從句中，當先行詞指物時，關系詞可用which或that，二者?？梢曰Q；但在下列情況中，只能用that，不用which：(1)當先行詞是all, a lot,(a)little, few, much, none, anything, something, everything, nothing等詞時。（3）如果定語從句的內(nèi)容對主句的內(nèi)容起消極作用或當非限制定語從句為否定時，則常用which，而不用as，如：She stole her friend’s money, which was tore up my photo, which upset drinks a lot everyday,which his wife doesn’t like at ．在正式文體中，以the way為先行詞的限制性定語從句通常以in which或 that 引導，如：The way in which you answered the questions was ，人們通常省略in which或 that : The way(in which)he spoke to us was don’t like the way(that)you laugh at ．關系詞的選擇1． 在非限制性定語從句中，關系代詞作主語，只能用who 指人，which指物；關系代詞做賓語，常用whom（口語中有時用who）指人，which指物，它們都不能用that代替。eg: He passed the exam, which/as he hoped he has left here, which greatly upsets ：（1）as引導的從句可以放在主句之前，而which引導的從句只能放在主句之后。試比較： All the books there, which have beautiful pictures in them, were written by the books there that have beautiful pictures in them were written by brother, who is eighteen years old, is a PLA man.（只有一個）His brother who is a PLA man is eighteen years old.（不止一個）4．有時，非限制性定語從句所修飾的不是某一個詞，而是整個主句或是主句中的一個部分，這時一般采用which或as來引導。另外，非限制性定語從句從意義上講，相當于一個并列句，在口語中使用并不普遍，在日常生活中，人們通常用并列句或簡單句來表達。這種從句在朗讀時要有停頓，在文字中通常用逗號與主句隔開。三．限制性定語從句與非限制性定語從句1．限制性定語從句說明先行詞的情況，對先行詞起限定作用，與先行詞關系十分密切，不可用逗號隔開，也不可省略，否則全句意義就不完整。why = for ：I was in Beijing on the day when(=on which)he office where(=in which)he works is on the third is the chief reason why(=for which)we did ． 當先行詞是表時間的time, day等和表地點的place, house等時，一定要注意分析從句的結(jié)構(gòu)，如果缺少主語或賓語時，關系詞應該用which或that, 缺少時間狀語或地點狀語時，才能用when或where，試比較：I’ll never forget the day when my hometown was ’ll never forget the days which/that we spent together last father works in a factory where radio parts are father works in a factory which/that makes radio ． when和where既可以引導限制性定語從句，也可以引導非限制性定語從句
