答案是1 d 2 c 3 a

Answer 1

D，这是一道考察情态动词的题。填空处表示说话人的允若。would 在此举的情况下没有这种用法，will可以表示意愿，允若，决定；且用于第二人称。shall可以表示说话人的允若且用于第二三人成。AB两项很容易就排除了。
2。大会还没有任何讨论，知道各分支机构的领导都到会。until引导的是时间状语从句。语句的时间，领导还没有到齐，故用将来时
3.考察suggest表示建议请求时用虚拟语气，排除BDwould rather do sth.但此句中would rather后是从句用虚拟语气，但不是should do类型故选A
这只是我的小小答案。得出正确答案后请告我一声，我都好久没好好的做过英语题了。
