题型:不详难度:来源:
Mother wanted to be a good provider, a role she _______ since her marriage to Father.
A.shouldersB.has been shouldering
C.is shoulderingD.shouldered

答案
B
解析

试题分析:考查时态:句意:妈妈想很好的养家糊口,这是她自从和爸爸结婚以来一直担负的责任,时间状语是since marriage to Father.可知用现在完成时或现在完成进行时,选B。
点评:英语中的时态主要由动词的形式决定,因此在学习英语时态时,要注意分析动词形式及具体语境,想象在那个特定的时间动作所发生的背景,这个动作是经常性动作、一般性动作、进行性动作、完成性动作还是将要发生的动作。现在完成进行时是表示过去动作一直持续到现在。
