Question

Since his father died three years ago,he ______(not,pay) any taxes.
has not paid
had not paid
do not pay
did not pay
这些填法有何区别,有何不妥?

Answer 1

首先,肯定这是一种表示过去动作,不能用do not pay
然后,看一下这个过去的动作对现在是否有影响,正是因为因为三年前他的父亲死了,他再也没交任何税了,所以肯定了对现在的影响,不能用did not pay
最后,had not paid它表示的是过去的过去,是以过去的时间为基点的,因为说这句话的时候对说的人应该是现在而不是过去
