Section_ⅣGrammar__Writing 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 语法图解 探究发现 ①In the corner, there is a garbage can around which are pieces of garbage and waste paper. ②David, we think, is the person to whom you should write. ③The policeman with whom Henry is talking in the office is a friend of mine. ④Perhaps there is a reason why the house is in a mess. ⑤This is the house where Lu Xun lived. ⑥I still remember those years when I lived with him. [我的发现] (1)例句①②③中含“介词＋关系代词”引导的定语从句，而且关系词作介词的宾语。 (2)例句④⑤⑥中含关系副词引导的定语从句，而且关系副词在从句中作状语。why作原因状语；where作地点状语；when作时间状语。 　　 一、“介词＋关系代词”引导的定语从句 1．“介词＋关系代词”结构 定语从句中的介词有时可置于关系代词之前，形成“介词＋关系代词”结构。关系代词通常是which和whom，which指物，whom指人。 [名师点津]　若定语从句中的短语是固定搭配，拆开便失去了原来的意义，则介词通常不能前置到关系代词之前。如look for, look after, take care of等。 This is the painting which/that he’s looking for. 这就是他正在找的那幅画。(从句中的look for为固定短语，不能拆开) [即时演练1] 用“介词＋关系代词”引导的定语从句合并句子 ①Liu Yang will never forget the day. She was carried into space by spaceship on that day. →Liu_Yang_will_never_forget_the_day_on_which_she_was_carried_into_space_by_spaceship. ②The store was broken into last night. My sister works in the store. →The_store_in_which_my_sister_works_was_broken_into_last_night. ③The reason is that he was ill yesterday. He did not hand in his homework for that reason. →The_reason_for_which_he_did_not_hand_in_his_homework_is_that_he_was_ill_yesterday. ④The English play was a great success. The students acted in it at the New Year’s party. →The_English_play_in_which_the_students_acted_at_the_New_Year’s_party_was_a_great_success. ⑤Who is the man? You shook hands with him just now. →Who_is_the_man_with_whom_you_shook_hands_just_now? 2．介词的确定方法 结合句意，一看先行词，二看从句的谓语动词与先行词的搭配来确定介词。 In this room, we saw a big table on which there were all kinds of fruits. 在这个房间里，我们看到一张上面放着各种各样的水果的大桌子。(which代指a big table，介词根据on the table 来确定) This is the man from whom I learned about the news./This is the man whom I learned about the news from. 我就是从这个人那儿听到那个消息的。(whom代指the man，介词根据learn ... from来确定) [即时演练2]　用适当的“介词＋关系
