二、 现在分词的形式变化 现在分词一般式表示与谓语同时发生的动作;完成式表示发生在谓语动词之前的动作。
eg: Hearing the bell, the students began to enter the classroom. 听见铃声, 学生们开始走进教室。(听见和进入两个动作同时发生)。
Having done the work, he went home. 完成了工作, 他就回家了。(完成工作发成在回家之前); 当句子的主语是分词动作的承受者时, 分词用被动语态(being done)。 如果要强调分词的动作先于谓语动作，就用分词完成式的被动形式(having been done)。
eg: The question being discussed is of great importance. 正在被讨论的问题是很重要的。
Having been criticized by the teacher，Li Ming gave up smoking. 被老师批评之后，李明戒了烟。三、现在分词考点直击
下面结合高考试题谈谈现在分词的考查重点：
[原题再现]
The bell ____the end of the period
rang, _____our heated discussion.
indicating; interrupting
B. indicated; interrupting
C. indicating; interrupted
D. indicated; interrupted答案 为A。本句的谓语动词是rang, 两个空白处都应使用非谓语动词, 逻辑主语是the bell, 因此应使用表示主动意义的现在分词。第一空是分词短语作定语, 第二空是分词短语作状语。
如果两个动作有先后, 一般不能用现在分词的完成式作定语, 而应使用定语从句。如:
The old man criticized the boy who had broken the window.(不宜用having broken the window)2. Though____ money, his parents managed to send him to university.
A. lacked B. lacking of
C. lacking D. lacked in
答案为C。lack与句子的主语构成逻辑上的主谓关系, 选用表示主动意义的现在分词，lack是及物动词, 后接宾语。1)当句子的主语不是分词的逻辑主语时, 分词应有自己的逻辑主语,这就是分词的独立主格结构。例如:
Time permitting, you can pay a visit to some places of interest in Hangzhou.如果时间允许的话, 你们可以参观一下杭州的一些名胜古迹。3.Finding her car stolen,____ .
A. a policeman was asked to help
B. the area was searching thoroughly
C. it was looked for everywhere
D. she hurried to a policeman for help
答案为D。根据现在分词短语finding her car stolen, 可以断定其逻辑主语是she。一、句型转换
