12、o,whom,whose,which,of which,when,where等，不用that或why,不能省略More examples with non-restrictive attributive clause:1.His mother,who loves him very much,is strict with him.2.China,which was founded in 1949,is becoming more and more powerful.3.Last summer I visited the Peoples Great Hall,in which many impor
13、tant meetings are held every year.Her brother who is now a soldier always encourages her to go to college.她当兵的哥哥总是鼓励她上大学。Her brother,who is now a soldier,always encourages her to go to college.她的哥哥，现在是一名士兵，总是鼓励她上大学。（她还有其他哥哥。）（她只有一个哥哥。）As is reported in the newspapers,talksbetween the two countries a
14、re makingprogress.2.有时as也可用作关系代词。Her house,which was built a hundred years ago,stood still in the earthquake.1.which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分，that不能用于引导非限制性定语从句。3.在非限定性定语从句中，用who,whom代表人，用which代表事物。The meeting was put off,which was exactly what we wanted.4.非限制性定语从句还能将整个主句作为先行词，对其进行修饰，这时从句谓语动词要
15、用第三人称单数。Tom,whom everyone suspected,turned out to be innocent.as 和which 引导非限制性定语从句的区别1.which引导的从句只能放在主句之后；as引导的从句可放在句首、句中或句尾。As is known to everybody,the moon travels round the earth once every month.Mike,as we expected,attended the meeting.He wasnt unconscious,as could be judged from his eyes.2.whi
16、ch既可代指先行词，又可代指整个主句的内容，相当于“and this”或“and that”，译为“这一点”。as只能代指整个主句的内容，常带有“正如”之意，且已形成固定结构。(as is known,as is reported,as is said,as is expected,as we know,etc.)My son now goes to the school,which I used to go to when I was a child.Einstein,as is known,is a famous scientist.As is reported,China has bec
17、ome an important country in the world.3.as在从句中作主语，从句中的谓语必须是系动词；而which则不一定。I have the same opinion as you(have).Dont read such books as are beyond your ability.4.先行词前有the same,such限定时，关系词只能用as。He is very strict,as is shown in his work.The man is very learned,as is described in the book.She wore the s
18、ame dress as her younger sister wore.她穿着跟她妹妹同样的衣服。She wore the same dress that she wore at Marys wedding.她穿着那件她参加玛丽婚礼所穿的衣服。(同一件)当先行词受the same 修饰时，有时也用that引导定语从句，但与as引导的定语从句意思有区别。(另外一件)5.主从之间存在逻辑上的因果关系时，关系词往往用which。Tom was late for school again and again,which made his teacher very angry.1.查理史密斯去年退休了
19、，他曾经是我的老师。Charles Smith,_ was my former teacher,retired last year.2.我去年买的的那幢房子带着个漂亮的花园。My house,_ I bought last year,has got a lovely garden.whowhich根据汉语意思，完成下列句子。3.这本小说很动人，我已经读了三遍。This novel,_ I have read three times,is very touching.4.他似乎没理解我的意思，这使我心烦。He seems not to have grasped what I meant,_ gr
20、eatly upsets me.5.液态水变为蒸汽，这就叫做蒸发。Liquid water changes to vapor,_ is called evaporation(蒸发).whichwhichwhichReview非限制性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限制性定语从句的前面往往有逗号隔开，如若将非限制性定语从句放在句子中间，前后都需要用逗号隔开。阅读短文，按照句子结构的语法性和上下文连贯的要求，在空格处使用合适的关系词填空。The mummy of an Egyptian woman _ died in 800 B.C.has just had an opera
