D.has seen
My grandmother___a lot of changes in Tianjin since.She came here.A.sees B.can see C.will see ↓D.has seen
since she came here意思是“自从她到这儿以后”,说明是发生了的事情.后面跟有这种since句式,那么前面的动词都用完成时,所以是has seen
选D，因为后面跟的句子是过去时。
since+过去某个时间点
for+时间长度
这两种情况引导的时间状语的句子，主句都用完成时。
例如：I have been here since last year.
I have been here for two years.
译为：自从我奶奶来这里，她看到了天津的很多变化。
A、sees是一般现在时的形式，与原意不符；
B、can see与will see 放在这边都不恰当
for+时间长度；而since+过去某个时间点
主句用完成时
