①There is not much furniture in the office.转自环 球 网 校edu24ol.com

　　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.转自环 球 网 校edu24ol.com

　　(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。
