hundred,six thousand,seven million等。6）当hundred,thousand等数词与of连用，表示不具体、不准确的数目时，词尾须加-s。如：thousands of students,millions of trees.二.序数词1）不规则变化2）以-ty结尾的表示“几十”的基数词，先把y变为i，再加-eth

oclock.2.分钟小于或等于30分钟的，用“分钟数past钟点数”形式；分钟数大于30分钟的，用“到下一个钟点所差的分钟数to下一个钟点数”形式,也可以依次读钟点数和分钟数。7:20 twenty past seven或seven twenty.3.注意两个特殊的表示时间的单位词：30分钟用half，15分钟用a quarter，如：6:30 读作：half past six 5:45 读作：a quarter to six 6:15 读作：a quarter past six（三）分数的表达方法表示分数时，分子用基数，分母用序数，分子大于1，分母用复数。分数修饰名词时，后用of短语。如：1/3 one third of teachers 3/7 three sevenths of the boys1/2,1/4分别用 a half和a quarter表示。（四）（四）“基数词名词形容词基数词名词形容词”结结构构“基数词名词形容词”只能用来放到名词前作定语。如：She is a 3-year-old girl.They live in a 7-storey-high building.注：这种结构中名词不能用复数，同时只能作定语。用作表语时，不用连字符，名词有复数。如：Tony is 10 years old this
