(05浙江2)A. this B that C. which D.it考点三：关系代词前介词的确定如何选定介词:1.根据从句中动词或形容词与先行词的搭配和逻辑关系e.g.(1) He is the man _____ whom I think you can depend .(2) He referred me to some books _____ which I am not very familiar.2. 根据先行词与介词的搭配习惯e.g. 1949 was the year _________the P.R.C. was founded3.根据从句所表达的意思e.g(1).The pen with which he is writing now was bought yesterday.(2).The gas without which we can not live is called oxygen.Practice1.

而which引导的定语从句只能在主句后面。

As代表前面主句意思时，有“正如…”之意，而which没有此意思，从句中的动词常是expect, know, see, think, want, suppose等。

as 的这种用法通常出现在一些固定短语之中如：1．as has been said before如上所述2．as may be imagined 正如可以想象出来的那样3．as is well known 众所周知4．as was expected 正如预料的那样5．as has been already pointed out正如已经指出的那样6．as we all can see 正如我们都会看到的那样② _____ is known to all, China is a developing country.②John, _____ you know, is a famous writer.③He failed in the maths exam, _______made his father angry.④Mary has been to Paris more than ten times, _____ I don’t believe.as 引导的非限制性定语从句The earth is round._____ is known to all.The earth is round,_____ is known to all._____ is known to all, the earth is round______ is known to all that the earth is round.as 引导的非限制性定语从句(1)This is the same pen as I lost.This is the same pen that I lost.as 引导的限制性定语从句(2)This is such an interesting book ____ we all like.This is so interesting a book _____ we all like.This is such an interesting book ____we all like it.This is so interesting a book ____we all like it.非限制性定语从句中的常考句型1. 要表示先行词的一部分时，可用“名词/代词/数词+ of +which/whom”的结构There are 50 students in our class, two- thirds of whom have been to Beijing.I picked up the apples, some of which were bad.2.介词+which+名词引导的定语从句She suffered from illness, in which case her mother had to stay home.3.Whose引导的非限定性定语从句They lived in a house, whose door opens to the south.They lived in a house, of which the door opens to the south.They lived in a house, the door of which opens to the south.考点五1、当先行词是a/the time，用什么关系词？2、当先行词是the way时，用什么关系词？3、先行词是point, case , situation和occasion时,用什么关系词？①It is the first time _______she has been inShanghai.②There was a time _______Chinese peoplehad a hard life.A. thatB. whichC. when解析：若先行词time表示次数，用that，并可省略若先行词time表示一段时间，用when 或at/during+whichI don’t like the way _____________you speak to her.解析：当先行词是way，意为方式方法时，关系代词有that, in which和省略三种情况。
