many a child_____to walk before he can speak.如题A.learn B.learns C.learned D.have learned
B
“many a + 单数可数名词”这种结构不是表单数概念,而是表复数概念,意为“很多.”,但是须牢记,这一结构作主语时,谓语动词在一般现在时态中要用第三人称单数形式,即动词后加s那一类.

B. Many a 作主语,谓语用单数。因句子后面用的是一般现在时的can,表示是一般时。故选B。

many a child__learns___to walk before he can speak.
这个句子应该是一般现在时。many a 就是很多的意思,但是是当单数的用法的。

B
many a +n.谓语用单数形式,意思为“很多”
