[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 “n”in 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.
