这句话使用了虚拟语气,主句的结构应是would /should/might +动词原形,所以要用would
关于虚拟语气的用法我这里有很详细的讲解,希望能够帮到楼主!
通常虚拟语气使用的场合有三种：
一、与现在事实相反
若与现在事实相反,虚拟语气的条件从句的谓语用过去式(be通常用were),主句谓语用“should (would,could,might)+动词原形”.如：
If you took a taxi,you'd get there quicker.如果你坐出租车去,你可以快一点到那里.(但你不坐)
If I knew her number I could ring her up.要是我知道她的电话号码,我就可以给她打电话了.(可惜我不知道)
二、与过去事实相反
若与过去事实相反,虚拟语气的条件从句的谓语用过去完成时(had+过去分词),主句谓语用“should (would,could,might)+have+过去分词”.如：
If I'd left sooner,I'd have been on time.要是我早点动身,我就准时到了.(但我动身太迟了)
If we had found him earlier we could have saved his life.要是我们当时早点找到他的话,我们就可以救活他.(可惜我们找到他太晚了)
三、与将来事实相反
若与将来事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用“should (would,could,might)+动词原形”.如：
If he went,would you go too?如果他去,你也去吗?(大概他不会去)
If I asked him,I'm sure he'd help us.如果我向他提出要求,肯定他会帮助我们.(不过我不打算这样做)
注意与说明：对于与将来事实相反的情形,请注意以下几点：
一是这里说的与将来事实相反,实为对将来情况的推测；
二是此用法中的条件从句谓语除用过去式外,有时也用“should+动词原形”(表示可能性极小,常译为“万一”)或“were to+动词原形”(表示与将来事实相反的假设)；
三是当条件从句使用“should+动词原形”这样的谓语时,主句谓语除可用“should (would,could,might)+动词原形”这样的虚拟语气外,也可用陈述语气或祈使语气.如：
I should see him,I'll tell him.万一我见到他,我就告诉他.
If it should rain tomorrow,don’t expect me.万一明天下雨,就别等我了.
希望我能够帮助到您～
这句话考察的是虚拟语气的时态
因为前面if条件句里面动词用的是could，为了保持时态的一致性，后面就要用would了~~
这句话用了虚拟语气哦
如果是表达对现在的虚拟 主句的结构就是would /should/might +动词原形了
