1. With tears on her face, the old lady watched the little boy__ to a hospital.

　　A. send B. to do sent C. being sent D. sending

　　【答案】C boy是send这个动作的宾语，所以要用被动式，因此排除B项和D项;这为女士看到得失一个瞬间动作，所以应该用进行时，因此选现在分词的被动式being sent.

　　2. Standing on the bank, the children watched the ship ___ with all kinds of goods.

　　A. loading B. being loaded C. to be loaded D. having loaded

　　【答案】B。本句为现在分词的被动做watch 的宾语补足语。因为宾语和宾补是动宾关系，而且表示动作正在进行，所以用现在分词的被动式;watch 也可以跟无to不定式做宾补，表示动作已经结束。Do you hear someone calling you 你听见有人叫你吗?(现在分词做宾补，表示动作正在进行。)Yes, I did. I heard him call me several times.是的，我听见他叫了我几次了。(不定式做宾补，表示动作已经结束)。
