   12  不定冠词 a 的使用


  cn.(countable nouns) VS un (uncountable nouns)
  名词前用不定冠词,或定冠词,或都不用。一般而言,只有一个正确答案。A 用与不用,意思完全发生变化
  Eg.
  She has long hair.(un.)
  There is a hair in my soup.(cn)
  I like a dog.喜欢吃狗肉。
  I like dogs.喜欢狗
  I ate 1 a hamburger 我吃了一个汉堡 (cn.)
  I ate hamburger 我吃了碎牛肉-(un. hamburger(Am.E) un.相当于mince(Br.E))
  I ate a cake.吃了一整个饼。
  I ate cake. 吃了些(一部分)饼
  注意:如果名词前面有a时后面是接了可数词,表整体。如果前面没有a ,后面是接不可数词。
  所以要注意,根据具体情况使用不定冠词

1 ate
v.吃,eat的过去式
  • I ate a whole box of chocolates.我吃了一整盒巧克力。
  • It's a long time since she ate out last time.她很长一段时间没在外面吃饭了。
