Hearingtheirteacher’svoice,thepupilsstoppedtalkingatonce.2．谓语动作发生在分词所表示的动作过程之中，用when/while+现在分词的一般式，分词的逻辑主语为句中的主语。如：Don’tbecarelesswhen/whilehavinganexam.3．分词所表示的动作完成之后，谓语动作才发生，则用现在分词的完成式，即havingdone的形式。分词的逻辑主语应是句中的主语。如：

Havingfinishedhishomework,theboywasallowedtowatchTVplay.Grammar***二、现在分词在句中作原因状语1．分词短语在句中作原因状语时，相当于一个原因状语从句。当分词所表示的动作与谓语动作同时发生或几乎同时发生时，用分词的一般形式。如：

Notknowinghowtoworkoutthedifficultphysicsproblem,heaskedtheteacherforhelp.2．分词表示的动作发生在谓语动作之前时，可以用现在分词的完成式在句中作原因状语。如：

Havinglivedwiththegirlfor5years,weallknowherverywell.Grammar**三、现在分词短语在句中作条件状语现在分词短语在句中作条件状语时，其逻辑主语为句中的主语，该短语相当于一个条件状语从句。如：Turningtotheleft,youwillfindthepathleadingtothepark.

四、现在分词短语在句中作让步状语现在分词短语在句中作让步状语时，其逻辑主语是句中的主语，相当于一个让步状语从句，有时分词前可以带有连接词although,whether,evenif,eventhough。如：Weighingalmostonehundredjin,thestonewasmovedbyhimalone.Grammar**五、现在分词短语在句中作结果状语现在分词短语在句中可以作结果状语，相当于一个结果状语从句，其逻辑主语是句中的主语。分词短语在句中作结果状语时，通常位于句末，中间有逗号。有时为了加强语气，就在分词前加thus。如：Theircarwascaughtinatrafficjam,thuscausingthedelay.

六、分词短语在句中表示方式或伴随情况现在分词短语可表示方式或伴随情况，用来说明动作发生的背景或情况。一般情况下，现在分词所表示的动作与谓语所表示的动作同时发生，它的逻辑主语就是句中的主语，谓语动词作为主要动作，而现在分词表示一个陪衬动作。如：Thechildrenranoutoftheroom,laughingandtalkingmerrily.Grammar**GrammarNow,pleasedothetasksonPages23-24inyourtextbook.
