36.We’ve had a good start, but next, more work needs ______ to achieve the final success.
A. being done B. do C. to be done D. to do
解析：答案是C。判断非谓语动词是要用主动式还是被动式，最基本的办法是看非谓语动词的逻辑主语与非谓语动词之间是主谓关系还是动宾关系——若是主谓关系，则非谓语动词用主动式；若是动宾关系，则非谓语动词用被动式。从意义上看，“工作”应该是需要“被做”，故要用不定式的被动式。不过值得一提的是，need也可后接动名词，此时则要用主动形式表示被动意义，所以如果将A改为doing，则也可视为正确答案。
37. _____ what he can do. He might get a job tomorrow. He might stay out of work for weeks

A. the door bell rang B. the doorbell rings
C. we heard the doorbell ring D. we heard the doorbell rings
