新东方新概念英语培训给大家整理了职称英语考试《综合类》基础语法辅导：单位词和不定代词，希望能帮助到大家。

单位词的使用

(1) 不可数名词表示多少，一般用much, (a) little, a lot of, enough 等词表达，要数1，2，3，4…时要用"量词"表达，常用的是a piece of (news, advice, furniture, information…)。

(2) 成双成对的名词一般用复数，如：a pair of trousers (裤子) / scissors(剪刀) / glasses (spectacles)(眼镜) / pliers(钳子)

(3) a couple of表示一对，或2-3…，如：a couple of days / people / things

(4) 记住以下量词表达方式：

a loaf (two loafs) of bread (一个(两个)面包)

a burst of laughter(一阵笑声)

a fit of anger / chill(一阵发怒 / 发冷)

a game of chess (一盘棋)

a lump of sugar (一块方糖)

10、其他应注意的数的表达形式

1)a three-year-old boy 比较The boy is three years old

2) five thousand people / several thousand people比较 thousands of people

表达具体数字时，thousand不加 "s"，后面不加 "of "; ten, million, billion情况以此类推。

3) One-third of the students have passed College English Test Band IV.

Two-thirds of the students have passed College English Test Band IV.

One-third of the population in this area is living below the poverty line.
