When I was a student in the university,I often thought about whether there ___ a way to prove P=NP.
(P=NP是一个计算科学中的难解问题,现在都没有被证明)
这个题中应该填 is 还是 was?
我记得以前还学过这种句子:
I knew that the earth orbits the sun when I was young.
这个是用一般现在时,表示客观事实。
这两个句子用法有关系吗?
was
从句时态和主句保持一致
你这不是客观事实啊
我们常见的事实是:地球绕着太阳转
光速比声速快什么的
was
但不是虚拟,只是一般过去时。
was 虚拟语气
was
was
都没有被证明的难题肯定不能算作客观事实,根据主谓一致,只能was了
was
was 是正确的,主从的时态保持一致,此处不存在客观事实问题
