请问下列句中"xxx",我可以用=>"yyy"来作替换吗?!
Although he "had finished" his homework before 8 o'clock,
he stayed in the library with his girlfriend.
=>"finished"
They "have been trying" different solutions to the problem;
I believe that, pretty soon, they will find the one that works.
=>"are trying"

1会怪怪的,因为有先后顺序 这边用过去式就没有那个时间流动感了 不过原则上来说应该也可以?(有时候其实不是文法问题 而是有没有人这样用的问题)2我觉得可以 have been trying已经尝试一阵子了 这边是强调已经付出的努力 are trying正在尝试 但是一般理解上不会认为你指的是说话当下正在尝试 而会认为你已经尝试一阵子了 这边感觉比较像刚起步的样子 时态的转换就只是语气上的变化而已
