Question

英语：什么是定语?如何判断在句中作定语?

Answer 1

修饰名词或代词的成分,常由形容词、名词(含所有格)、代词(物主、指示、疑问、不定)、介词短语、不定式(短语)充当,
如：Put it in the top drawer.(把它放在最上层的抽屉里.) /
France and Switzerland are European countries.(法国和瑞士是欧洲国家.) /
His mother and father are both college teachers.(他的父母都是大学教师.) /
This is the day that I can never forget in my life.(这是我一辈子难忘的日子.)
(2) 单词做定语时一般放在被修饰的名词前面,而且有一定的次序：
顺口溜：限定描绘大长高,形状年龄和辛老,颜色国籍出材料,作用类别往后靠
(3) 时间副词(now,then,today,yesterday,...)、地点副词(here,there,back,in,out,home,...作定语时放在被修饰的名词后面.如：I could not find my way out,so I stayed there all along.(我找不到出去的路,所以就一直呆在那儿.)
(4) 介词短语修饰名词时只能放在名词的后面：The monkey in the cage was caught yesterday.(笼子里的猴子是昨天逮着的.)
(5) 形容词修饰复合不定代词时,往往后置.如：He remembered everything unusual.(他记得所有不寻常的事情.)
(6) 定语还可以用从句充当,参考 定语从句.
(7) 注意：由于定语属于修饰性的成分,因此它常归入主语、宾语、表语之中,不作为句子的主要成分
