could would should 在虚拟语气中是如何区别使用的?
1.在if虚拟语气条件句的主句中用would,could,should,might+动词原形.一般总是用would不错,可以译为“就会”；
有“可能会”、“也许会”之意时,用could,might较好；有“应该会”之意时用should 较好.如：
If he had not been busy,he would/could/should/might have helped you.他不忙的话,会/可能会/应该/也许会帮你忙的.
2.在“命令、要求、坚持、建议”等词后的that从句中用should＋动词原形,should可以省去.

它们的语气是
should 大于 could 大于 would
也就是说should语气强烈
could语气一般
would语气很委婉

去查语法书吧
