16、等。(3) 表示原因的先行词一般只有reason 一个。1.关系副词使用的几种变化1)关系副词通常也可以用“that+ 介词后置 ”代替或省略；2_在正式文体中，也可以使用“介词 +which ”的结构。that is the river where i used to swim. ( 关系副词 )that is the river that i used to swim in.

20、son who had gone missing two years before.a. thatb. whichc. whered. whenpart 4 限定性定语从句和非限定性定语从句1. 非限定性定语从句的由来tom is the only student who has been admitted to harvard in my class.汤姆是我们班唯一一个已经被哈佛大学录取的学生。the principal, who was seated on my right, delivered an exciting speech.校长发表了一个令人振奋的演讲，当时他就坐在我右边。2.

21、 限定性与非限定性定语从句的意义区别the old man has two sons who serve in the army.老人有两个当兵的儿子。the old man has two sons, who serve in the army.老人有两个儿子，都当兵。非限定性定语从句有时可以像一个并列句，例如：he has a walk after dinner every evening, which is good for his health.= he has a walk after dinner every evening, and this is good for his he

22、alth. he likes reading books, which i am delighted to hear.= he likes reading books and i am delighted to hear that.非限定性定语从句还可以从意义上像一个状语从句，表示原因、目的、结果、条件、让步等。例如：the new engineer, who has read the instructions, failed in the project.归纳总结?限定性定语从句非限定性定语从句意义起限定作用，是主句不可缺少的成分起补充说明作用，省去后不影响主句的意思形式与先行词间无逗号常用

23、逗号与主句分开翻译常译成前置定语常译成并列的分句4.非限定性定语从句的引导词的问题一般来说，除了关系代词that 和关系副词why ，其他定语从句的引导词均可以引导非限定性定语从句。例如：his speech, which inspired everyone, was well received.a student, who was admitted to an ordinary university, was greatly disappointed. the cinema, whose roof was damaged in the storm, will be brought down.

24、they will fly to new york next friday, where they have planned to stay for a few weeks. you can come next weekend, when the books will be ready for you.、which引导的非限定性定语从句as 和 which 在引导非限定性定语从句时的相同点和区别：1) 相同点： as 和 which 都可以指代整个句子的内容。the meeting was put off ， which/as was exactly what we wanted.这次会议延期

25、了，这正是我们所希望的。2) 不同点： as 引导的从句既可以位于主句前，也可位于主句后，主从句没有前后逻辑关系，常表示 “正如”；而 which 引导的从句只能位于主句后，主从句常有一定的因果关系或前后顺序，常表示“这一点”，相当于and this 或 and that 。liquid water changes to vapor, which is called evaporation.液态水变为蒸汽， 这就叫做蒸发。as everyone knows ， all that glitters is not gold. =all that glitters， as everyone know

26、s， is not gold. =all that glitters is not gold， as everyone knows.众所周知，并不是所有发光的东西都是金子。part 5 定语从句使用的注意事项1. 分析成分的能力和意识(1) 如果空白后面紧跟着动词的，明显缺少的是主语。mr. goodman has to be away on business onfeb. 8th, happens to be his wife s birthday.a. whichb. whenc. thatd. on which(2) 及物动词后必然有宾语，即如果及物动词后面没有宾语，先行词就是作动词的宾

27、语。the science museum, we visitedduring a recent trip to britain,is one of london s tourist attractions.【2008 江苏高考】a. whichb. whatc. thatd. where(3) 不及物动词后没有宾语，在不缺少主语的情况下，先行词则通常作状语等成分。- is that the small town you often refer to?- right, just the one you know i used to work for years.a. thatb. whichc.

28、 whered. what(4) 介词后面通常要跟宾语，如果介词后面没有宾语，则先行词通常作这个介词的宾语。-do you have anything to say for yourselves?-yes， there s one point we must insist on a whyb wherec howd /2. 并列连词的陷阱tom has two brothers, both of whom love sports.tom has two brothers and both of them love sports.(简单的并列连词：and, but, so, or, yet)意为 “方式，方法 ”，作先行词时的关系词的选择问题1)用 “介词 +which ”引导定语从句；例如：i don
