    A

    The hotel is full, so if you haven't made a reservation, I am afraid I can't give a room.

    旅馆已经满了,所以如果你没有事先预约的话,恐怕我不能提供你房间。

    B

    We got the acceptance letter about a month after sending in our proposal.

    在提交申请大约一个月后,我们收到了同意通知书。

    现在分词作状语,表主动语态,相当于We got the accpetance letter about a month after we sent in our proposal.

    B

    Polio is a viral disease that has been brought under control.

    小儿麻痹症是一种病毒性疾病,它已经得到控制。
