定语从句

在复合句中修饰名词、代词的从句叫定语从句。一、先行词先行词指人：who /that先行词指物：which/ that定语从句一般紧跟被修饰的名词或代词（即先行词）后二、关系代词关系代词代替先行词在句子中担当成分，所以从句中不可再出现其他代替先行词的代词。三、翻译方法   “…. 的”1、Whom: 先行词指人，则代替先行词在定语从句中充当宾语（包括介词的宾语）, 与who的区别是如果前面带介词则必须用whom。eg:This is the teacher whom\who we like best.这位就是我们最喜欢的老师。I don’t like the boy to whom you are talking.我不喜欢和你说话的男生。2、Whose : 指人或物，作定语，表示 “…的”eg: Harry is the boy whose mother is our math teacher.Harry的妈妈是我们的数学老师。关系代词只能用that的情况1先行词前有序数词修饰时This is the first gift that my parents bought me.这是我父母给我买的第一份礼物。2先行词前有形容词最高级修饰时This is the most exciting film that I have ever seen.这是我看过最激动人心的电影。3先行词是不定代词Is there anything that you want in this shop?这家店里有你想要的东西吗？4先行词是人和物时He talked about some writers and books that were unknown to us all.他和我们说了一些我们不知道的作家和书籍。5先行词被all , little , the only , the very(就是，正是), the last 等词修饰时This is the last place that I want to visit.这是我最后一个想参观的景点。6特殊疑问句以who 或which 开头Who is the girl that is making a speech on the platform?在讲台发表演讲的女孩是谁？当关系代词前使用介词时：1物+介词+whichThis is the train by which we went to Beijing.这是我们去北京的火车。2人+ 介词 + whomThis is the teacher to whom my mother is talking.这就是和我妈妈交谈的那位老师。关系副词的用法：1when指时间，其先行词表示时间，when在定语从句中作时间状语This was the time when he arrived.这是他到达的时间。2where指地点，其先行词表示地点，where在定语从句中作地点状语This is the place where he works.这是他工作的地点。3why 指原因，其先行词是原因，why在定语从句中做原因状语Nobody knows the reason why he is often late for school.没人知道他为什么上学总迟到。
