表达数目与数量的特别方法

  2008-11-17 14:28 】 【我要纠错
  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:  ① There is not much furniture in the office.  ② There 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。
