    不定冠词a/an的用法

      前此说过了“定冠词的常见用法”,意犹未尽。本文就来谈谈不定冠词(indefinite articles) a/an 的用法。

      不定冠词最基本的用途就是用来表示“一”这概念,如:

      ① A stitch in time saves nine.

      ② Jason is an internationally known scholar.

      此外,a/an 还有下列 6 种用途:

      ㈠常和time、measurement等有关的名词连用,以表示“每—” 的概念,如:

      ③ I teach five days a week.

      ④ This type of vegetables is sold at one dollar a kilo.

      ⑤ My car usually runs sixty kilometres an hour.

      ㈡常和 hundred, thousand, dozen 以及数目及数量连用,如:

      ⑥ That factory turns out at least a hundred tyres a day.

      ⑦ Noel's monthly salary is a thousand dollars.

      ⑧ I have a number of sponsored students.

      ⑨ Mary has a lot of money.

      ㈢在“of / at”后面出现,以表示“同一类”这概念,如:

      ⑩ Birds of a feather flock together.

      11. Please come one at a time.

      12. Things of a kind come together, so do people of a mind.

      ㈣常在“rather, quite, many, half, what, such”等字后面出现,形成固定用法,如:

      13. Tom is rather a fool.

      14. I think Chinese is quite a useful language.

      15. Many a student has asked that question.

      16. The visitor left half an hour ago.

      17. What a fine day it is!

      18. How can you say such a thing?

      ㈤用在“so, as, too, how +形容词”这些结构里,如:

      19. We have not had so hot a day before.

      20. Susan is as clever a girl as Anna.

      21. That is too difficult a book for beginners.

      22. No one knew how serious a problem it was until later.

      ㈥出现在许多惯用语中,如:

      23. Bob always has a bone to pick with others.

      24. Some students turned a deaf ear to the teacher's advice.

      25. All must learn a language with an eye to mastering it.

      26. I hope you will make an effort to attend the meeting punctually.

      27. Jason has an aversion to being idle.

      28. The news of Jack's sudden resignation came as a bolt from the blue.
