1. ________, she worked with greater enthusiasm.
A. Encouraging B. Encouraged
C. Being encouraged D. Having encouraged
答：选C.指受到鼓励。受到鼓励应该是被动，可答案A,B都为主动，故是错的。答案B虽也是被动，但表示的时间在前，不妥。两个动作应该是同时进行更妥当。
2. She never went to any place without someone _______ her.
A. to accompany B. to have accompanied
C. accompany D. having accompanied
答：选A.to accompany her既可看作someone的定语，也可以看成是介词without宾语someone的补语。前后两动作应该是同时进行的，可答案B,D表示的时间在前，C答案用动词原形，根本就不对。
3. A puma（美洲狮）escaped from the London zoo, ______ fear and terror among the people.
A. having created B. creating C. to have created D. create
答：选B,creating现在分词表示结果。
4. The only good thing ________ is that the print and the pictures are excellent.
A. which you can say these newspapers
B. about which you can say it about these newspapers
C. that you can say it about these newspapers
D. that you can say about these newspapers
答：选D.定语从句that you can say about these newspapers修饰The only good thing，that又在从句中作say的宾语。其它几个答案的错误在于：
答案A中which无法在从句中作任何成分，答案B,多出一个it,且出现两个about；答案C也是多了一个it。
