如题:-Has your daughter come back from Australia?
-Yes, she there for 3 years.
答案是stayed,请问能否用had stayed?我理解是她回到家是过去发生的事情,从过去的过去(进入澳大利亚)到过去(回家)一共3年,因此可以用过去完成时。
Yes, she stayed there for 3 years. (既然已经回来了,那样 stayed 就是指过去,正确。)
Yes, she had stayed there for 3 years. (因为句子语境没说明何时回来的,所以,过去完成时缺少必要的参照物,肯定慎用。)
