【例句呈现】观察以下句子,注意动词-ing形式所作的成分及用法.1.Seeing the sun rising above the surface of the sea,we let out a shout of joy.2.The boy was caught cheating in the last exam.3.With a native villager acting as our guide,we had no trouble getting around.4.Not feeling very well that morning,he went to see the doctor.5.When walking down the street,I came across an old friend of mine.6.Having finished all his homework,the boy went out to play football.7.The professor being ill,the lecture had to be put off.【用法小结】1.在句1至句3中,动词-ing形式作宾语补足语：动词-ing形式作宾补,表示宾语正在做或一直做某事.动词-ing形式作宾补时句子可以变为含被动语态的句子,这时动词-ing形式就在被动句中成了主语补足语,说明主语正在进行动词-ing形式的动作.介词with也可接动词-ing形式作宾补,此时with后的宾语是动词-ing形式动作的发出者.2.在句4至句7中,动词-ing形式作状语：动词-ing形式作状语,常表示原因、方式、时间、条件、结果、伴随等意义,且常可转换为对应的状语从句.如：句4 = As he didn’t feel very well ...动词-ing形式作状语,前边往往可以加when,while,if,unless,once,although等连词,构成“连词 + 动词-ing形式”结构.动词-ing形式的完成式作状语,表示动词-ing形式的动作发生在谓语动作之前.动词-ing形式作状语时,其逻辑主语与句子的主语要一致.当动词-ing形式的逻辑主语与句子的主语不一致时,就要在动词-ing形式前加上自己的逻辑主语（名词或代词）,构成独立主格结构(如句7).【即学即练】1.—Come on,please give me some ideas about the project.—Sorry.With so much work _____ my mind,I almost break down.(福建2007)A.filled B.filling C.to fill D.being filled2.I smell something _____ in the kitchen.Can I call you back in a minute?(宁夏2007)A.burning B.burnt C.being burnt D.to be burnt3.The glass doors have taken the place of the wooden ones at the entrance,______ in the natural light during the day.(天津2007)A.to let B.letting C.let D.having let4.When ______ different cultures,we often pay attention only to the differences without noticing the many similarities.(浙江2006)A.compared B.being compared C.comparing D.having compared5.While watching television,______.（2005全国卷III）A.the doorbell rang B.the doorbell rings C.we heard the doorbell ring D.we heard the doorbell rings6.______ in the queue for half an hour,Tom suddenly realized that he had left his wallet at home.(北京2004)A.To wait B.Have waited C.Having waited D.To have waitedKey:1-6 BABCCC
