2、ut message.(主语)2.The girl is my best friend.She spoke just now._ 3.He always buys some books.He never read them._ 注意点:1.)定语从句一般直接跟在先行词的后面:e.g.4.The man who lives next door sells vegetables.The man sells vegetables who lives next door.()5.The car which my uncle just bought was destroyed in the earthq

5、ensive.第二讲 whose 的用法:关系代词与其后的名词构成所有格,即“的”时,它既可以修饰指人的先行词,也可以修饰指物的先行词。e.g.1.The girl is my daughter.Her work got the first prize.The girl whose work got the first prize is my daughter.2.The book is not mine.The cover of it is red.The book whose cover is red is not mine (The book the cover of which is
6、red is not mine)3.Do you know anyone?His family is in Xian._ 4.I live in the room.The windows of it face south._ 5.The chair has been repaired.The leg of it was broken._ 限制性定语从句与非限制性定语从句 1、限制性定语从句:从句与主句关系密切,去掉从句,主句意义不完整,甚至不合逻辑。e.g.I was the only person in our office who was invited.(去掉定语从句,意思就不完整)2、
7、非限制性定语从句:从句对先行词关系不密切,去掉定从句,意思仍然完整。形式上用逗号隔开,不能 that 用引导。e.g.Toms father,who is over sixty,still works hard day and night.(who 引导非限制性定语从句,整个句子可分成两句来翻译)that 与 which 的区别 1)用 that 而不用 which 的情况 先行词为不定代词 all,anything,nothing,;先行词有最高级修饰,有序数词修饰;先行词有 only,very,any 等词修饰;先行词既有人又有物时。e.g.There is nothing that ca
