A
过去一个时间点开始的直到现在(或将来还有可能持续我们不管)发生的事,我们选用现在完成时,而不是过去完成时(过去的一个时间点为基准已经完成了的动作用过去完成时),
只有a b符合现在完成 差别在于动作的延续性和非延续性,当然要选择延续性动词了,因为前面有since then“从那时起”是一个时间段 所以要用延续的 be动词
have been in love
D
d
B
在过去之前,不是过去的过去,所以用现在完成时。这里是说一个动作:爱上了对方,用fall in love with
D
句话的意思是:自从他们彼此相爱后,他们就搬到了那座新的城市.
说明在搬到新城市之前他们已经相爱了,前面的"move"用的是过去时,所以相爱就是在过去的过去了,所以是过去完成时
