B A. which B. as C. than D. like限制性定语从句与非限制性定语从句的区别区别一：形式不同 限定性定语从句主句和从句之间不用逗号隔开，口语中使用时也不停顿；而非限定性定语从句与主句之间通常有逗号隔开，口语中使用时有停顿。区别二：功能不同限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意不完整或概念不清；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意仍然清楚、完整。如：People who take physical exercise live longer. 进行体育锻炼的人活得长些。(若把从句去掉句子就失去意义)His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。(若把从句去句子意义仍然完整)区别三：翻译不同在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。如：He is the man whose car was stolen. 他就是汽车被窃的那个人。Ive invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。区别四：含义不同I have a sister who is a doctor. 我有一个医生的姐姐。(姐姐不止一个)I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。(只有一个姐姐)区别五：先行词不同限定性定语从句的先行词只能是名词或代词，而非限定性定语从句的先行词则可以是名词或代词，也可以是短语或句子；另外，当先行词为专有名词或其他具有独一无二性的普通名词时，通常要用非限制性定语从句，而不用限制性定语从句。如：Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(which指drive too fast)He changed his mind, which made me very angry. 他改变了主意，这使我很生气。(which指整个主句)Mr. Smith, who is our boss, will leave for Japan next week. 我们的老板史密斯先生下周要去日本。(先行词为专有名词，要用非限制性定语从句修饰)Her father, who has a lot of money, wishes her to study abroad. 她父亲很有钱，希望她出国学习。(先行词为表独一无二意义的普通名词，要用非限制性定语从句修饰)区别六：关系词不同关系词that和why可用于限制性定语从句中，通常不用于非限制性定语从句；另外，在限制性定语从句中，关系词有时可以省略，而在非限制性定语从句中关系词一律不省略。关系代词 whom 在限制性定语从句中作宾语时可用 who 代替 whom ，但 whom 在非限制性定语从句中作宾语时不可用 who 来代替。1. This is the girl who/whom I met in the street. 2. A young man had a new girl friend，whom he wanted to impress. 先行词 a new girl friend 在非限制性定语从句中作宾语，不可用 who 代替 whom . This is the book（which/that）he lost yesterday. 先行词 the book 在限制性定语从句中作宾语，关系代词 which 或 that 可以省略。 The book, which he lost yesterday, has been found. 先行词 the book 在非限制性定语从句中作宾语，关系代词 which 不可省。介词+关系代词当关系代词在定语从句中作介词宾语时，我们通常用“介词关系代词”引导定语从句。如果指“人”，用“介词whom”；如果指“物”，用“介词which”。例如：The man who/whom you spoke to was a scientist.The man to whom you spoke was a scientist.The city that/which she lives in is far away.The city in which she lives is far away.使用“介词关系代词”要注意以下几点：(一)选用介词的依据：(1) 根据定语从句中谓语动词的搭配习惯(即固定短语)。例如：Yesterday we visited the West Lake for which Hang Zhou is famous.(2) 根据先行词的搭配习惯(约定俗成，不一定是短语)。例如：The old woman with whom you talked just now is a famous artist.Where is the supermarket in which you bought the laptop last week? (3) 根据句子的意思来选择。例如：The naughty boy made a hole in the wall through which he could see what is happening outside.He lives in a lovely village, at the back of which is a hill. They finally climbed up the mountain, on top of which many strange birds were seen. Look at the photo. This is Mr. Green, in front of whom sit three(4) 表示“所有”关系或“整体中的一部分”时，通常用介词of。例如：I have about 20 books, half of which were written by Bing Xin, the famous writer. He has three sisters, all of whom are abroad.(二)在定语从句中，含介词的短语动词不可拆开使用(短语拆开后含义发生变化)，如look after, look for, take care of等。例如：The babies whom the nurses are looking after are very healthy.(正)The babies after whom the nurses are looking are very healthy.(误)I saw the watch that/which you are looking for ?The old man (who/whom/that) I am looking after is better .The number of the children (who/whom/that) she takes care of is 30.(三) 关系代词whose+名词 引导的定语从句可转化为 the+名词+of+ which / whom 或 of+ which/whom+ the +名词结构；of 表所属关系。例如：The building whose roof was damaged in the earthquake has been repaired.=The building of which the roof was damaged in the earthquake has been repaired.= The building the roof of which was damaged in the earthquake has been repaired.I live in a room whose windows are all broken.=I live in a room of which the windows are all broken.= I live in a room the windows of which are all broken.This is my teacher whose handwriting is excellent.= This is my teacher the handwriting of whom is excellent.= This is my teacher of whom the handwriting is excellent.（四）不定代词+of+ which/ whom 引导的定语从句可化为of+ which/ whom+ 不定代词 结构；这也是高考常考点。其中用到的不定代词有some, any, none, both, all, many, a few, few, a little, little, either, neither, one, 等等。例如:There are 40 students in our class, most of whom（=of whom most）like English.These are books written by Mark Twain, one of which（=of which one）was read to me by my fatherShe has two sons, neither of whom（=of whom neither）is a teacher.She has many books, none of which(=of which none) is interesting.介词+关系代词练习1. I will never forget the day _on which_ we studied together.2.

This is the heroof whichwe are proud.6. There are three things _about which_ she is not sure.6. My glasses, without which I cant see, were lost yesterday.7.

we will go on a field trip.如果明天不下雨，我们就去郊游。Unless you observed the traffic rules, the accident would occur in time. 如果你不遵守交通规则，交通事故迟早就会发生。6.hardly-when-, no sooner-than-主句使用过去完成时，从句是一般过去时。   该句型的意思就是：“一就”。如：No sooner had I left my house than it began to rain. 我刚刚离开家，天就开始下雨了。Hardly had we finished our homework when he came to visit us. 我们一完成我们的家庭作业，他就来访了。7.in order that & so that 引导的目的状语从句中，一般采用将来时态或情态动词+动词原形。如：Answer the question in a loud enough voice in order that you can be heard clearly.用足够大的声音回答这个问题，以便能够被清晰地听到。Many senior students are working hard so that they will go to college.许多高中生为了上大学正在努力学习。They got up early in order that they would catch the early bus.他们早起，目的就是赶上早班公共汽车。 三、         语序  状语从句的语序一般采用陈述语气，但如下状语从句“与众不同”。1as引导的让步状语从句，应采用如下语序：adj/adv/n./verb + as +S + V., + 主句。如：Hard as he worked, Bruce failed for the seventh time.Child as he is, the naughty boy knows more than some adults.Tried as Edison had for 1000 times, he never gave up.   说明：从句前为名词时，名词不加冠词。2however/no m
