选择 He ( )look after his mother yesterday.
A.needed to
B.musted
C.have to
D.has to
我要讲解,不许说一些专业的,什么情态动词什么之类,姐姐我听不懂,讲简单一点,比如help sb to do sth

选择 He ( )look after his mother yesterday.A.needed to B.mustedC.have toD.has to 我要讲解,不许说一些专业的,什么情态动词什么之类,姐姐我听不懂,讲简单一点,比如help sb to do sth
选A
首先有yesterday(昨天)决定了要用过去式,排除C D
再次,没有musted这个形式
所以只能选A
意思是他昨天需要去照顾他的母亲.
