When expressions of measurement, amount and quantity are used as adjectives, they are normally singular. 當(dāng)度量單位，數(shù)量等被用作形容詞時(shí)，通常用單數(shù)形式。如：
a ten-mile walk
a twenty-pound note
a thirty-year period
ten two-hour lessons
Possessives are often used in expressions of time.在時(shí)間的表述中，經(jīng)常用所有格。
a week’s holiday
two hours’ delay
2 hundred, thousand, dozen, etc
Typical mistake: she had at least four hundreds of lovers.
When these words are used after a number or several, they do not have –s and of is not used. 當(dāng)這些詞用在一個(gè)數(shù)字，或者several后面時(shí)，不要加s也不要用of. 如：
She had at least four hundred lovers.
It cost several thousand pounds.
In other cases, the plural form is hundreds(of), dozens (of),etc. 在其他情況下，用復(fù)數(shù)形式，后面通常跟著of. 如：
I’ve seen it hundreds of times.
But you’ve got dozens of dresses.
3 half
Typical mistakes:
Only half us could come.
I live half of a mile from here.
Give me the half.
Half can be used before a noun, with or without of (like all and both).
在名詞前面，half可以跟of連用，也可以單獨(dú)使用。
More than half (of) my friends are foreigners.
She spends half (of) her time traveling.
Before a personal pronoun, half of is always used.
在人稱代詞前面，通常用half of。
‘Can I have my records back?’- ‘ok, but I’ve only had time to listen to half of them.’
Only half of us could come last Tuesday.
Of is not used with half when we are talking about measurements or quantities.
當(dāng)談到度量或者數(shù)量時(shí)，half 后面不可以用of.
My old home is about half a mile from here.
Half a dozen eggs and half a pound of butter,please.
Cecily drank half a bottle of Scotch last night.
The expression one and a half is followed by a plural noun.
one and a half 后面用復(fù)數(shù)名詞。
I’ve been waiting for one and a half hours.
