比如:
Her book,“Determined,Dedicated and Disciplined To Be Fit,”came (come) out in April just before she turned eighty.
The bus had left before I arrived.
为什么两个不一样呢?什么时候用一般过去时,什么时候用过去完成时。
Her book,“Determined,Dedicated and Disciplined To Be Fit,”came (come) out in April just before she turned eighty.
The bus had left before I arrived.
解答如下:
A时间=I arrived (过去某个时间,即离现在较近的过去时间)
B时间=the bus had left (在A时间的之前的某个时间,即离现在较远的过去时间)发生在过去A时间之前的动作即过去的过去,用过去完成时态。
