39 代词是用来代替名词以避免重复的词,如:
John was in love with Mary.When Mary was seriously ill, John waited on Mary morning,noon and night. John was so anxious about Mary's health.
But Mary recovered quickly.
在这些句子中,Mary和John重复过多,若使用代词,句子就好得多:
John was in love with Mary.When she was seriously ill, he waited on her morning,noon and night. He was so anxious about her health.But she re-covered quickly.
40 从实用观点来看,代词可以分为5类:
(1)人称代词(Personal Pronouns),如I,me,my,mine;
(2)疑问代词(Interrogative Pronouns),如who,which,what;
(3)指示代词(Demonstrative Pronouns),如this,those,that;
(4)不定代词(Indefinite Pronouns),如some,any,all;
(5)关系代词(Relative Pronouns),如who,which,that。
本章主要讨论人称代词,其他代词将在其他章讨论。例如,疑问代词将和疑问副词、疑问形容词一起讨论,因为它们有许多相似之处。同样,关系代词将和关系副词、关系形容词一起讨论。
