(二) 正误辨析
［误］Tom's mother is taller than my.
［正］Tom's mother is taller than mine.
［析］形容词性物主代词可以作定语，也就是讲它可以作形容词，如：my book，而这句话的意思是：汤姆的妈妈比我的妈妈高。比较的对象是my mother,也就是mine。
［误］We have a lot of homework to do today. So we need two or three hours to finish them.
［正］We have a lot of homework to do today. So we need two or three hours to finish it.
［析］在应用代词时，要注意人称，格与数的一致性。这里it所代替的是不可数名词homework， 所以应用it。
