问题描述:

So far this year we____
3.So far this year we _______ a fall in house prices by between 5 and 10 percent.(2008福建)
A saw B see C has seen D have seen 选第四个吗,为什么啊,我是感觉的,

So far都出现了 很明显的完成式标志了哟~

D So far 后面加完成时

so far this year 意思是从过去到现在为止 用完成时的呀 表完成

so far 要用完成时态的

so far 到目前为止
看到这个短语,基本上该句就是完成时
本句主语是:we(我们),所以完成时用have done
因为这样,所以D是对的
意思:今年到现在为止,我们看到房价跌了5-10%.
