系副詞即表時(shí)間when,地點(diǎn)where ,原因why,等詞,在句中的具體用法要看句子的意思了.介詞加關(guān)系代詞一般情況下就是介詞加which的情況,即in which = where/when (大的時(shí)間年月季等或大的地點(diǎn)國(guó)家、城市等) at which=where/when(小的時(shí)間點(diǎn) 某一時(shí)刻 或小的地點(diǎn) 在學(xué)校、家等) for which=why 因此,在定語從句中,有介詞時(shí),必選which,其意與所對(duì)應(yīng)的關(guān)系副詞是一樣的.
還要根據(jù)句子的結(jié)構(gòu)搭配哦
選用介詞的依據(jù)：
(1) for which=Why
Yesterday we visited the West Lake for which Hangzhou is famous.
(2) with whom和某人
The old woman with whom you talked just now is a famous artist.
(3) through which穿過某處
The naughty boy made a hole in the wall through which he could see what is happening outside.
(4) 表示“所有”關(guān)系或“整體中的一部分”時(shí),通常用介詞of.例如：
I have about 20 books,half of which were written by Bing Xin,the famous writer.
(二)在定語從句中,含介詞的短語動(dòng)詞不可拆開使用(短語拆開后含義發(fā)生變化),如look after,look for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.(誤)
【三】“of which / whom”有時(shí)可以用“whose＋名詞”結(jié)構(gòu)來改寫.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.
好了,報(bào)告完畢.
