语法教学:
  复习定语从句
  定语从句分为限定性定语从句和非限定性定语从句。
  1) 限定性定语从句:限定性定语从句对所修饰的先行词起限定作用。 限定性定语从句中关系词的使用列表如下:
  在句中的作用关系词说明
  主语 关系代词:who/that(指人) which/that(指物 关系代词不能省略
  宾语 who/whom/that(指人)
  which/that(指物) 关系代词在非正式
  文体中可以省略
  定语 whose 名词前表所有关系
  介词+关系代词 whom(指人) which(指物) 关系代词不能用who或that
  whose(定语) 名词前表所有关系
  状语 关系副词:when(时间) where(地点)why(原因) 先行词为表时间、
  地点等的名词

  例:
  ①Anna was an American writer who/that interviewed Mao Ze dong in Yaan.(指人作主语)
  安娜是一位当年曾在延安采访毛泽东的美国作家。
  ②The friends whom/who/that we met in the park were from Egypt.(指人作宾语)
  我们在公园里遇见的朋友来自埃及。
  ③A taxi is a car (that/which)you can hire.(指物作宾语) 出租车是你可以租用的小汽车。
  ④Many forests where the animals lived were destroyed.(作状语)
  动物栖息生活的许多森林遭到破坏。
  ⑤We ought to help those families whose men are in the army.(作定语)
  我们应该帮助那些男人在部队的家庭。
  ⑥He looked at the box from which the voice came.(介词+关系代词)
  他看着那只传出声音的方箱子。

  2)非限定性定语从句:非限定性.定语从句对所修饰的先行词(句子)起补充说明的作用,不起限定作用。从句中使用关系代词who,whom,which,whose和关系副词when,where等,不使用关系代词that,作宾语的whom不能用who代替。
  例:They visited the city of Hangzhou,which is famous for its beautiful scene.他们参观了杭州城,它以风景秀丽而闻名。
  非限定性从句中关系词指代整个句子时,用关系代词which。试比较:
  ①Big floods hit some parts of China in the summer of 1998,which caused a great damage to the country.1998年夏中国部分地区遭受特大洪灾,给国家带来了巨大损失。(指代整个句子)
  ②They got married on July 1,1997,when Hong Kong returned to our motherland.他们于1997年7月1日喜结良缘,香港在这一天回归祖国。(指代时间作状语)
  学习中应注意的问题(一)
  1)先行词为表示时间或地点的名词在从句中作主语或宾语时关系词的使用。当先行词为表示时间或地点的名词时,在从句中作主语或宾语时,应使用代词which或that,不能用副词when或where.
  ①a:Ill never forget the days which/that I spent in the country.(which作spent的宾语)
