高中英语-定语从句语法点课件.ppt

as 引导定语从句常出现于the same…as…, such…as…, as…as…, so…as…中。As 引导的定语从句常用省略形式，as 在从句中既可指人或物，也可指整个句子，指整个句子时可位于句首，句尾或句中。As 引导定语从句时，在从句中常作主语，宾语，表语等。 Such people as have made great contributions to the world should be greatly respected. 那些对世界作出巨大贡献的人应受到极大的尊重。 (as与such连用，在定语从句中做主语)语，表语等。 Let’s meet at the same place as we did yesterday. 咱们在昨天见面的同一地方见面吧。 （as 与the same连用，在定语从句中做状语） Shakespeare is a famous writer, as everybody knows. 众所周知， 莎士比亚是著名的作家。 (as代替整个从句，做knows 的宾语，位于句尾) Shakespeare, as everybody knows, is a famous writer. （位于句中） 这类as引导的定语从句通常有固定表达。 As I can remember正如我所记的 As often happens 正如经常发的 As you see 这一点你明白 As is well known 众所周知 As is expected 正如预料的那样 As can be seen 看得出来 方式 关系副词 that = in which This is the way that( in which) he did it I don’t lie the way that(=in which) you laugh at her 提醒一：关系代词或关系副词的选择有两个原则：1）先行词是人还是物;2)先行词在从句中作什么成分。若先行词在从句中作主语，宾语，或定语，则选关系代词；若在从句中作状语，则选关系副词。 1We will remember those days that/which we spent together.(作宾语) 2we will remember those days when we played by the sea.(作状语) 提醒二：关系代词在定语从句中作主语时，根据先行词的单复数决定从句谓语动词的单复数。 1He is the only one of the students who knows French (the only one 为先行词) 2He is one of the students who know French (students 为先行词) 提醒三：关系代词的省略：在限制性定语从句中，关系代词作动词宾语或介词宾语（这时介词不能在关系代词前）时常可省略。 The boy (that/who/whom) we saw last night was Tom 提醒四：定语从句常见错误 1缺先行词：Is this school that you visited last year? 该句缺先行词，应在school后面 加上the one 2 缺引导词：Chinese eat a lot of sugar often have bad teeth 应在children后面加上who 关系代词作主语时不能省略 3成分重复：This is the house where I lived there years ago. Where 和there 句子成分重复，应去掉there whom 在从句中作宾语,指人 3) The person to whom you just talked is Mr. Li. （宾语） 4) Mr. Read is the professor to whom you should write . （宾语） 2) This is the book whose cover is blue. whose 在从句中作定语，指人或物 1) Miss Flower is the teacher whose house caught fire last week. whose 引导的定语从句应注意以下几点： 1.whose 引导定语从句，在从句中作定语其后应紧跟名词 That’s the child whose drawing we looked at just now. 2. whose 引导定语从句，其先行词可指人，也可指物 I saw some trees whose leaves we
