in case,on condition that,suppose等后面怎么接虚拟语气?
例如:You’d better take the keys in case I’m out.(牛津高阶)Take your coat just in case it rains/ it should rain.(朗文当代英语词典)In case也可解作“如果,假如”.这是美国的用法,用在句子开头,相当于if,这时从句通常不需要用虚拟语气.例如:In case you can’t come,give me a call before I leave for work.(麦克米伦英语词典)In case they are late,we can always sit in the bar.(朗文当代)On condition that...是“只有”“条件是”的意思,可以使用虚拟语气,也可以不用.使用虚拟语气的话,常用should+V.的形式,should可以省略.例句:I’ll come on condition that John is invited.(朗文当代)They agree to lend him the car on condition he (should) return it in a week.Suppose表示“假如”时,后面的从句可用虚拟语气,也可不用.使用虚拟语气时,用过去时表示假设,而不用should+v.Suppose flight are fully booked on that day—which other day could we go?(麦克米伦英语词典)
