英语单选题（要答案，也要原因）

Question

1.In many people's opinion,that company,though relatively small,is pleasant ___ with.
A.to deal B.dealing C.to be dealt D.dealt
2.The experment shows that proper amounts of exercise,if _____ regularly,can improve our health.
A.being carried out B.carrying out C.carried out D.to carry out

Answer 1

1.A 后半句有省略：is pleasant (for sb.) to deal with.这句话跟The moring air is good (for us) to breathe.一个道理，千万不能在这里用被动。
2.C 连词+分词的固定用法，表被动，比较基础。其实多读几遍，就觉得这种用法很顺，其它选项放进去都很怪。
