計量表達(dá)法：
數(shù)量+單位+形容詞。
The street is two kilometers long.
That boy can jump four meters away.(此處不用far, 見49) The fish is five kilos heavy.
The street is forty meters wide. This baby is only six months old.
若計量表達(dá)的后面跟有名詞，則要用連字符，單位不用復(fù)數(shù)。
They dug an eight-meter-deep hole. /. I bought a 10-kilo-heavy fish.
It’s a piece of 2-meter-thick ice. / They built a 50-meter-wide street.
It’s a two-month holiday. She is a three-child mother. (最后兩句計量中省略了形容詞)
