问题探究
▲基数词的用法
顺口溜帮你巧记基数词：
基数词，不难记，找出规律很容易。零至十二形各异，一个一个单独记。后加?teen为“十几”，thirteen，fifteen看仔细，eighteen只有一个t。表示“几十”要加?ty，twenty，thirty是特例；forty，fifty更厉害，和eighty一起搞例外。表示数字“几十几”，连字符号要切记。要表“几百几”，and常把百、十系(美式英语可省略and)；还有一点须注意，“几百”后别把?s立。
▲辨析how
much与how
many
(1)how
much对物品的价格进行提问。如：
How
much
is
the
skirt？这条裙子多少钱？
(2)how
much后接不可数名词，用于提问不可数名词的数量。如：
How
much
milk
do
you
drink
every
day？你每天喝多少牛奶？
(3)how
many后接可数名词复数，用于提问可数名词的数量。如：
How
many
apples
do
you
have？你有多少个苹果？
