　　 The secretary worked late into the night, ___a long speech for the president. 内容来自

A. to prepare　 B. preparing　 C. prepared　 D. was preparing　

　　谜底B. 此处不连词，不能选D，否则浮现了两个谓语动词worked跟was preparing。 只能在B，C入选一个。又因前后两个动作同时产生，且与主语为主动关系，应用当初分词。 CopyRight .com

2）先于自动词 内容来自

典型基础英语在线学习例题 内容来自

　　 ___ a reply, he decided to write again.　

A. Not receiving　　B. Receiving not　 C. Not having received　 D. Having not received　　

　 答案C. 本题考察分词的时态与分词的否定式。根据题意判断，分词的动作（接信）发生在谓语动词的动作（信念再写信）之前，因此用分词的实现式。分词的否认式的构成 为not +分词，故选C。该句可理解为：Because he had not received a reply, he decided to write again.
