结合句子意思，考察非谓语动词与相应逻辑主语的关系，若为主动关系，用主动式；若为被动关系，用被动式。此时要特别注意，过去分词没有相应的被动式，因为它本身可以表示被动。如：
1. The repairs cost a lot, but it’s money well_____.
A. to spend B. spent C. being spent D. spending
分析：答案选B。因money与spend是被动关系，所以用过去分词。
2. The prize of the game show is＄30000 and an all expenses _____ vacation to China.
A. paying B. paid C. to be paid D. being paid
分析：答案选B。因all expenses与pay是被动关系，故用过去分词。注意句中的an 不是修饰
expenses，而是修饰vacation。
3. When _____help, one often says, “Thank you.” Or “It’s kind of you.”
A. offering B. to offer C. to be offered D. offered
分析：答案选 D。因一个人说“谢谢”，应当是他被提供了帮助，所以要用过去分词，When offered help… =When he is offered help…
