小学英语数词及专项训练
一、数词的分类:基数词和序数词。基数用于表示数量多少,而基数词用于表示次序,常在日期中出现。
区别:基数词前面没有“the”;序数词前一定要有“the”。1、超过二十以上的两位数需要在个位和十位之间加上“”。如:21twe
tyo
e2、用基数词来修饰可数名词时,一定别忘了它的复数形式。如:十八个男孩eightee
boys3、用基数词修饰不可数名词时,如是复数,变它的量词为复数。如:两碗米饭twobowlsofrice4、序数词一般加“th”,特殊的有:firstseco
dthirdfiftheighth
i
thtwelfth;二十及二十以外的整十:twe
tieththirtiethfortieth…“第几十几”:前面整十不变,后面“几”改为序数词。如:88eightyeighth巧记基数词和序数词:
123特殊记加th从4起8少t9去e逢5逢12ve变f2090y要变ie若是几十几前基后序别倒位
