为什么用does 不用 has?
The baby is generally healthy ,but every now and then she ___does__ catch a cold.为什么用does 不用 has?
does是一般现在时第三人称单数的助动词,助动词+实义动词,表示强调,加强语气.这句话的意思是：这个婴儿一般都很健康,但是不时地他也会感冒.
does用于强调，小孩大致上都很健康，当他现在确实得了感冒
为什么不能用has呢？
如果用了这句话就变成了现在完成时，而现在完成时要求：has+done(过去分词）
catch很明显是动词原形，所以这里就排除了用has的可能性
希望能帮到你
does 强调句
has的话，从语法上也讲不通，has catch
因为这里是一般现在时的一个表述.
every now and then意思是 -- 有时.
整句话意思:这个宝宝身体不错,可有时也会生病.
does是强调.
has 后面接P.P 即，动词的过去分词
does 在这里是起强调作用
宝宝平时都很健实，但也会时不时地感冒
every now and then 是“时不时”的意思
表一般现在时的时间状语
不能用现在完成时，即 has caught
