数词的分类
数词可以分为基数词、序数词、分数、小数、百分数等。
基数词
基数词可以作数量词用或者代词用。

two cabbages, three pounds of tomatoes and twelve oranges. 两个洋白菜、三磅西红柿和12个橘子。
序数词
序数词通常在基数词后面加上后缀-th,如：six(基数词)；sixth(序数词)。
分数
英语中分数的构成为：一个基数词加一个序数词。分子用基数词，分母用序数词。充当分子的基数词是“1”时，分母直接使用序数词；充当分子的基数词是“2”或“2”以上的时候，分母要用“序数词 + -s”。如：one third 1/3, nine sixteenths 9/16, two and two thirds 2*2/3等。
小数
分数可用小数来表示，请注意小数的读法：
0.5 读作 nought point five 或 point five
2.5 读作 two point five
2.05 读作 two point nought five 或two point o five
百分数
8%读作 eight percent 或 eight per cent
25%读作 twenty-five percent 或 twenty-five per cent
99%读作 ninety-nine percent 或 ninety-nine per cent
近似的数量
如：about, almost,exactly, fewer than, at least, less than, more than, nearly,over,under等，与数词连用时表示不确切的数量。

not(any)、no和none, (not) (a)little 与 (not) a bit 等的区别。
not (any), no 和 none 的区别
构成否定的方式可以用not来否定动词，也可以用no来否定后面的动词。

a great deal/amount of 与 a large / great number of 的区别
a great deal / amount of 都有much之意，其后面应该接不可数名词。而a great / large number of 都有 many 之意，其后应该接可数名词复数。

（not)、(a)little与(not) a bit 及 (a) few 的区别
few和a few；little 和 a little
a few 用于修饰可数名词复数
a little 用来修饰不可数名词。
不带不定冠词a时，这两个词都表示否定的意思，强调概念少，一般表示”几乎一点儿也没有“的意思。如需要再加强程度，可以与very 连用。

a little 和 a bit 在肯定句中几乎是通用的。
