  所以teacher就是一个先行词。 再说下它的用法： 1、先行词指人时，引导词可用Who,Whom,及that,其中当引导词在句中作主语时用Who或that；当其充当宾语时用whom或that，在非正式宾语中也可用who，也可省略。
   a That boy who/that broke the window is called Tom。 b The person to whom you just talked is Mr Li。
   b 句可改为：The person(that/whom/who)you just talked to is Mr Li。 2、先行词指物时，引导词用that或which a。
  They planted the trees which didn’t need much water。 b 。The fish (which)we bought were not fresh。
   3、先行词指时间时，引导词用When/on which或in which a。I still remember the day when/on which I first came to Bei jing。
   b。I'll never forget the year when/ on which we worked on the farm。 4、先行词指地点时，引导词用Where或in which This is the house where/in which we lived last year。
   或:This is the house that/which we lived in last year。 5、whose在定语从句中作定语时，可用来指人，也可以用来指物，如: a。

   二、物殊情况： 尽管有以上基本原则，但要学好定语从句更应注意以下特殊情况； Ⅰ、当定语从句的先行词为表示人的不定代词，如 anyone,anybody,everyone,everybody,noone,nobody,all， these ，those等时,用who而不用that Those who break the rule are pulished。
   Anybody who had eyes could see the elephant was like a snake。 Ⅱ。以who或which作主语的特殊疑问句中先行词指人，引导词只用That,如: a。
  Who is the person that is standing at the gate ? b。Which of you that knows something about English doesn’t know this word? Ⅲ、先行词指物时引导词用that而不用which的情况: 1、先行词有序数词或形容词最高级修饰时， This is the best composition that has been written in English。

   Ⅳ。time为先行词时，前边如有序数词修饰时，定语从句引导词用that或什么也不用，如没序数词修饰时，用when或that均可 a。This is the last time(that)I shall give you a lesson。
