回答：could,may,might,must,ought1.We(ought )to sceed this time,we won't be given another chance.ought to 意思为：应当，应该。是和to连在一起的，所以你看到后面有to ,就应该联想到应该填ought.译文：这次我们应当成功，下次我们不再有机会了；2.Vehicles(could)not pass until the big stone was removed from the road.could表示能够，是can的过去时，比can用法更婉转。译文：直到那块大石头从马路上挪开后车辆才能够通行；3.You(may)discuss the matter with her,but I'd rather you didn't.may表示可能，可以，语气比might要强，可能性要比might大。译文：这事你可以和她商量，不过我还是情愿你不要；4.Pilots(ought)to have good eyesight.ought to：应当，应该。 是连在一起的，所以你看到后面有to ,就应该联想到应该填ought.理由同第一题。译文：飞行员应当有很好的视力;5.She(could)play the violin at the age of five.could表示：能够，是can的过去时，表示能力。译文：在五岁时她就能拉小提琴了；6.(Could )you send me an application form?could这里表示能够，用在疑问句中表示语气客气，婉转。译文：你能够寄给我一份申请表么？7.She said she(might )not see her son for another two years.might表示可能性，可能性很小。译文：她说她可能另外那两年见不到她儿子；8.I(must)look funny in this hat!must表示必须，要，另外还表示推断，意思是：一定，准是。译文：我戴上这顶帽子肯定看起来准傻傻的！！
