式应当做相应的调整.如:

You would be much better now if you had taken my advice.
If father hadn’t sent me,I shouldn’t be here.
If he knew this,it would have had to be by accident.

语气.如:

refund the purchase money.
一个坚持,两个命令, 三个建议,四个要求
1.insist 2. order, command 3. advise, suggest, propose
4. demand , require, request, desire
从句中的动词使用should + 动词原形或者将should省略

重要的是我们要照顾好病人。
虚拟语气在 在 as if /as though 从句中

一. as if (as though) +表语从句
