09年中考英语单词分类复习策略2 二、 冠词? (一) 知识概要 冠词在英语中只有3个词,分为两类:不定冠词a与an,定冠词the。 a用在以辅音开始的单数名词前,an用于以元音开始的单词前。不定冠词用来表示一类事物中泛指的某一事物,而定冠词则用于特指的某一个或某些事物,可用于不可数名词、可数名词单数及可数名词复数前。 (二) 正误辨析 [误]This building is an university. [正]This building is a university. [析]a用于以辅音音素开始的单词前,而an用于以元音音素开始的单词前,而不是元音字母开头的单词前。university的第一个音素是[j],所以用a而不要用an。又如:There is a n in the word.是错句,应为:There is an nin the word.因字母n的发音的第一个音素是元音。要注意的还有hour因其第一个字母h不发音,所以应该用an hour。例如: I need an hour to finish the work. It is a useful dictionary. It is a European country. I bought a used car. [误]I need a umbrella because it looks like raining. [正]I need an umbrella because it looks like raining. [析]因umbrella的第一个音素是元音,所以应用an.常用的情况有:an old man, an English teacher, an elephant, an idea, an hour ago, an honest boy。 |
