would have lost是表推测还是虚拟语气
The millions of calculations involved,had they been done by hand,would have lost all the practical value by the time they were finished.
1.The millions of calculations (which is) involved,if they had been done by hand,would…?
2.by the time (when they) were finished?
3.以上我补充的对不?
4..

虚拟语气
前面有had they been done by hand
就是如果是通过手工完成的
had提前得倒装形式,虚拟语气.
1.The millions of calculations (which is) involved,if they had been done by hand,would…?
不对
正确说法是 Millions of calculations were involved,if they had been done by hand.

would have lost是表推测还是虚拟语气英语表推测语气(不是虚拟语气) would have done应该不仅仅指虚拟语气吧,是否应该还有推测的含义 would have like to 是虚拟语气么? 虚拟语气中'd怎么区别是had还是would? I would have gone 请问这是虚拟语气还是过去将来完成时?还是都是只不过说法不同? 判断一下这里的can是表示虚拟语气还是推测虚拟语气would have done 的用法 would have been 一定为虚拟语气? 口语语法You can see where he'd have trouble.'d would是虚拟语气还是will过 would have done和虚拟语气有关 would have sth是个什么语法概念? 虚拟语气中对过去的虚拟主句否定是用would have not done or would not have done?
