2、宾语从句中的虚拟语气
（1） wish后的宾语从句
wish(that)+ did/were(would/should do) 表示与现在或将来相反
Had done(would/should have done) 表示与过去相反
（2）某些动词表示愿望、要求、建议和命令等。从句形式为：（should）+动词原形
常用的动词有：advise、order、command、decide、propose、demand、recommend、request、require、insist、suggest、urge
注意：insist表示“坚持认为，坚持说”时，从句中不用虚拟语气；表示“坚持要求”时，从句用虚拟语气。suggest表示“暗示，表明”时，从句不用虚拟语气；表示“建议”时，从句用虚拟语气。

3、表语从句和同位语从句中的虚拟语气
表示建议、命令、主张、目的和愿望等名词后面的表语从句或同位语从句中用虚拟语气。其形式为：（should）+动词原形。
常用的名词有：advice、preference、demand、proposal、desire、request、requirement、necessity、order、suggestion
