计量表达法：
数量+单位+形容词。
The street is two kilometers long.
That boy can jump four meters away.(此处不用far, 见49) The fish is five kilos heavy.
The street is forty meters wide. This baby is only six months old.
若计量表达的后面跟有名词，则要用连字符，单位不用复数。
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. (最后两句计量中省略了形容词)
