问题描述:

---( )children are there in you fanily?----Three.A.How much B.How often C.How many D.How old

选A
这个how often是表示频率的,问你多长时间生次病
其实三个选项在语法上都没有问题
可是B 和C有点不符合现实情况
那有人三天就生次病的
也不会有人不到一周就生病吧……
所以就选A咯!!

选C
How many children are there in you fanily?----Three
在你家里有几个小孩?——三个
AHow much 修饰不可数名词,而children是可数名词,所以应排除
B.How often试问多久一次,表示频率,不合题意
DHow old是问多少岁,不合题意
