新概念第三册12课文问题

perhaps there is an element of truth in both these pictures,but few of us have had the opportunity to find out.

two men who recently spent five days on a coral island wished they had stayed there longer.

 第一句的 but few of us have had the opportunity to find out.为什么要用现在完成时态呢,去掉现在完成时态不可以吗?
第二句的 wished they had stayed there longer,为什么要用过去完成时态呢?那这样翻译出来不就成了希望已经在那呆的更久了吗?课本的译文是说希望能够在那呆更久

Answer 1

第一句之所以用完成时,是因为,这个动作对现在仍然有影响,就是说,人们很少有机会去发现的这个动作,以前很少有机会,现在仍然很少有机会.
第二句是虚拟,wish是提示你用虚拟,因此时态后退一个时态
