iknow a litter bit about italy as my wife and i ____there several years agoa are going b had been c went d have been 为什么不用现在完成时呢
答案 C
时间段+ago表示的是时间点概念.是指从现在算起的某一段时间前的那个时间点.因为是过去,所以要用一般过去时.
现在完成时的作用是动作发生在过去,现在已经结束或仍在进行,强调动作的结果对现在事实所产生的影响.如果有时间状语,必须是时间段状语.例如；
I know about I taly as my wife and I have been here since several years ago.
我了解意大利因为我和妻子从几年前起就一直在这.
加上个 since 自从,就表示自从几年前到现在,一个时间段概念.
对现在进行时提问的副词是how long 而不是when.
供参考,祝进步!

因为有表示过去时间的状语：several years ago。

因为是几年前去过，是过去已经发生的。
