  1.在复合句中,修饰名词或代词的从句称为定语从句被定语从句修饰的名词或代词叫先行词。连接先行词与定语从句的引导词叫关系词,其中 which, that, who, whom 这些词叫关系代词,它们在句中用来指人或事物,在定语从句中作主语或宾语,whom 只能作宾语。作宾语时,关系代词可省略。

  2.A.Here is the pen that you lost yesterday. (that 用来指物, 在从句中作宾语, 可以省略掉, that 也可用 which 代替。)

  B.The girl who told me the news is not here now. (who 用来指人, 在从句中作主语, that 可以代替 who 用来指人。)

  C.The woman who / whom / that you saw in the park is our English teacher. (whom 只能用来指人, 只能作宾语, 在从句中可以省略。)

  3.刚才所说的6个句子的宾语从句, 关系代词只能用 that 而不能用其他关系代词, 下面逐个分类分析:

  A.先行词是 all, much, little, none, the one 或由 no-, any-, every- 构成的复合代词时。

  B.先行词被 all, every, some, little, much, the only, the very 等修饰时。

  C.先行词是序数词或被序数词限定时。

  D.先行词被形容词最高级修饰时。

  E.先行词同时包含人和事物时。

  F.当主句是 who 或 which 开头的特殊疑问句时, 为避免重复, 习惯上多用 that。

  4.

  A.She heard a terrible noise, which brought her heart into her mouth.

  非限制性定语从句与主句用逗号隔开, 非限制性定语从句引导词不用that。

  B.The games in which the young men competed were difficult.

  介词in也可以放在定语从句谓语动词之后, 关系代词which或that可省略。

  5.定语从句中, “介词+关系代词”引导定语从句。关系词前选什么样的介词对我们来说有时束手无策, 希望老师能够归纳出几点巧妙的判断规律。
