表达数目和数量的特别方法

  大家知道,不可数名词没有表示复数的"-s"标志,因此前面不可有数目字,只可以有数量词。例如我们可以说①, 不可以说②:

  ①There is not much furniture in the office.

  ②There are not many furnitures in the office.

  这是不是说不可数名词就不可数呢?不然。相反的,不可数名词也是可数的,主要方法是借重单位词(unit word),如:

  a piece of, a cup of, a drop of, a lump of, a handful of, a flash of, a blade of, a head of, a bar of, an ear of等。

  如果数目是超过"一",就以确实数目取代"一"。例如:

  two pieces of, three cups of 和 five lumps of 等。

  现在试试把上述这类单位词和适当的不可数名词连用。

  ① Mr Li has just bought a piece of new furniture.

  ② Give me a cup of cold water, please.

  ③ Please put two lumps of sugar in my coffee.

  ④ The boy picked up two handfuls of sand from the beach.

  ⑤ We saw a flash of lightning in the sky.

  ⑥ The gardener pulled out blades of wild grass from the garden.

  ⑦ She gave bars of chocolate to the visiting children.

  有些名词如 scissors, trousers, spectacles, tongs, pliers 等,都以复数形式出现,  如:

  ⑧ The scissors are lying on the table.

  ⑨ The spectacles fit me nicely.

  如果要给这些名词表示单数"一"的意思,就要借重单位词了。例如:

  ⑩ Mary has just bought a pair of scissors.

  (11) The mechanic repaired the machine with a set of pliers.

  现代英语注重简洁,合成形容词便应运而生,其中有一种是用来表示数目的,方法是:

  "数目+名词",如:a five-year plan, a ten-dollar note, a two-hour meeting, a three-day conference等。

  必须注意的是,这种合成形容词中的名词,只能以单数形式出现。如果用复数,就错了,如:

  a five-years plan, a ten-dollars note, a two-hours meeting, a three-days conference.

  这类错误,虽然频率不是很高,但也是要留意才好。

  如果没有把握,不妨用完整的表达方式,如:

  a five-year plan→a plan of five years, a ten-dollar note→a note of ten dollars, a three-day conference→a conference of three days 等。
