將 half 用作分配詞

分配限定詞 half 用來談論一個劃分為二的群體,在用作分配詞的形式有很多種。其它部分也可以用於相同的形式,只是較為少見。

half 後可以接不定冠詞(a 或 an)為首的測量單位,在這種用法上,分配限定詞為一種測量法。

舉例
  • I had half a cup of milk left.
  • I bought half a kilo of flour.
  • He ran half a mile this morning.
  • I will be back in half a minute.

half 可以接名詞,但兩者之中必須夾帶定冠詞、不定冠詞、指示代名詞或所有格代名詞。在這種情況下,它指的是一個具體、實質上的劃分。而 half 接 of 並不會改變意思。

舉例
  • Half the people have already left.
  • Half of an apple isn't very much lunch.
  • Did you use half my sugar?
  • I will need half of the flour for my cake.
  • I earned half of that money last summer.
  • She found half these frogs in the river.
  • I spent half that time on my project.
  • You can take half of those books back.
  • I've invited half my friends to the party.
  • I've used up half of our eggs.
  • You wasted half your money on that!

half 後可以接 of + 複數代名詞。

舉例
  • Half of us are going.
  • He scolded half of you but he let the rest off.
  • You couldn't find half of them?
