4、ng is talking to？正在與李明談話的老師是誰？（作賓語）注意：（1）當(dāng)定語從句中含有介詞，介詞放在句末時(shí)，who， that， which可省略，但介詞在關(guān)系代詞前時(shí)，只能用“介詞+which/whom”結(jié)構(gòu)。例如：This is the house in which we lived last year.這是我們?nèi)ツ昃幼〉姆孔?。Please tell me from whom you borrowed the English novel.請告訴我你從誰那借的這本英文小說。（2）含有介詞的固定動(dòng)詞詞組中，介詞不可前置，只能放在原來的位置上。例如：This is the perso

7、an remember well the persons and some pictures that I saw in the room.我能清楚記得我在那個(gè)房間所見到的人和一些照片。e.以who或which引導(dǎo)的特殊疑問句，為避免重復(fù)，只能用that.例如：Who is the girl that is crying？ 正在哭泣的那個(gè)女孩是誰？f.主句是there be 結(jié)構(gòu)，修飾主語的定語從句用that，而不用which.例如：There is a book on the desk that belongs to Tom. 桌子上那本書是湯姆的。（5）關(guān)系詞只能用which，而不用tha
