A Heating B To be heated C Heated D Heat 答案：C 注意：（1） 选择现在分词还是过去分词，关键看主句的主语。如分词的动作是由主句的主语发出，分词就用现在分词，反之就用过去分词。试比较：（Being）Used for a long time, the book looks old.由于用了很长时间，这本书看上去很旧。Using the book, I find it useful.在使用的过程中，我发现这本书很有用。（2） 分词作状语时，其逻辑主语必须和主句的主语一致，如果不一致，就用独立主格结构，即在分词前加上它的逻辑主语。现在分词的完成式主要用于作状语，一般不用作定语。When_, the museum will be open to the public next year.A completed B completing C being completed D to be completed答案：A_ such heavy pollution already, it may now be too late to clean up the river.A Having suffered B Suffering C To suffer D Suffered答案：A3、 作表语现在分词作表语多表示主语具有的特征，过去分词作表语多指主语所处的状态。如：The film is touching.The glass is broken.She looked tired with cooking.He remained standing beside the table.Im very_ with my own cooking. It looks nice and smells delicious.Mm, it does have a _ smell.A pleasant; pleased B pleased; pleased C pleasant; pleasant D pleased; pleasant答案：D4、 作宾语补足语分词和不定式一样，在一些感官动词或使役动词后作宾语补足语。如：I smell something burning.I heard him singing the song.I heard my name called.I cant make myself understood in English.I found my car missing.Ill have my watch repaired.我想把我的手表修一下。The managers discussed the plan that they would like to see _ the next year.A carry out B carrying out C carried out D to carry out 答案：C一、考点聚焦1、非谓语动词的句法功能名称语 法 功 能 主语宾语宾语补足语表语定语状语不定式动名词现在分词过去分词4、分词复习应注意的几个问题（1）现在分词在句中作时间、原因、伴随、条件、结果等状语。时间状语（分词作状语前面可加when, while等）Hearing the good news, he jumped with greatjoy.Not having finished her work in time, the boss fired her.原因状语Seeing nobody at home, he decided to leave them a note伴随状语The girls came in, following their parents.结果状语The poor old man died, leaving nothing to his children.注意：现在分词作状语的几个特性。时间性。与谓语动词同时发生，用一般时，如发生在谓语动作之前时则用完成式having done。语态性。与句子的主语之间的关系，是主谓关系或动宾关系。遵循的规则“主动进行，被动完成”。人称一致性。分词的逻辑主语就是句子的主语。（2）分词作表语。S. + be + 动词-ed表示被动，主语是人；S. + be + 动词-ing表示主动，主语是物。分词作宾补不定式作宾补的区别： 感官动词 动词原形做了某事S+ + 宾语 + 现在分词正在做某事 使役动词 过去分词做了或被做5、复习过去分词应注意的几个问题过去分词作状语，相当于一个状语从句，有来说明原因、时间、条件等。（1）过去分词作原因状语Tired by the trip, he soon feel asleep.= Because he was tired by the trip, he soon fell asleep.Lost in thought , he almost ran into a car.=As he was lost in thought, he almost ran into a car.（2）作时间状语Seen from the hill, the city looks like a garden.=When the city is seen from the hill, it looks like a garden.（3）作条件状语Given more time, I would have worked out the problem.=If I have been given more time, I would have worked out the problem.（4）伴随状语The teacher came in, followed by some students.=The teacher came in and was followed by some students.分词短语作状语时，通常与主句中的主语在逻辑上一致，但有时它也可以有自己独立的逻辑上的主语，这种结构称为独立主格结构。如：Her grandfather being ill, she had to stay at home looking after him.。（6）不定式的完成时的特殊用法。表示不定式中谓语动词发生的动作先于主句的谓语动词发出的动作。The novel was said to have been published.I regret to have been with you for so many years.seem、appear、be sai
