Learning about grammar 动词-ing形式起到名词、形容词和副词的作用，在句中可作主语、宾语、表语、状语和宾语补足语，但不能单独构成谓语，表示的是主动与进行，其构成形式如下， 一：-ing的形式：-ing有一般式和完成式。及物动词的-ing还有主动语态和被动语态，而不及物动词的-ing则没有被动语态。现在以及物动词make 和不及物动词go为例，将其-ing各种形式列表如下： 动词 语态 形式 及物动词make 不及物动词go 主动语态 被动语态 主动语态 （否定）一般式 （not）making （not）being made （not）going （否定）完成式 （not）having made （not）having been made （not）having gone         1.–ing短语的一般式和完成式 Eg     (talk) and_____(laugh), the students went into the classroom. , he couldn’t afford to buy a house. (poor) 2–ing短语的完成式(having + 过去分词)作状语,表示在句中谓语之前发生的动作和状态。 eg: __________the tent, they started to cook their supper.(put) (= After they had put up the tent, they started to cook their supper. ___________many times,he decided to give it up.(fail) (=after he had failed many times,he decided to give it up.) 3 作状语用的–ing短语,其逻辑主语必须同句中主语相一致。 eg: Having found the cause, they continued the experiment.(正) Having found the cause, the experiment continued. (误) 但有时它也可以有自己独立的逻辑主语,这种结构称为独立主格结构。 eg: So many people _____(absent) ,(=As so many people were absent) they decided to put the meeting off. Weather ________(permit), (=If weather permits) we’ll go there on foot. _                      ____(judge)by his accent, he must be from America. 4) 现在分词短语的被动语态表示被动又正在进行的动作 The bridge_________will be finished in the next month.(build) 现在分词短语的完成被动式基本相当于过去分词的含义，既表被动，又表完成 _________many times, he still can’t remember his son’s telephone number.(tell) 5) 现在分词短语的否定形式由 “not+ 现在分词”构成,完成式的否定式“not +having +现在分词” __ _______(没有收到儿子的来信)her son for a long time, the mother worried a great deal.(hear) Exercise 一；用所给词的适当形式填空 1._______(not know) anything about the accident,he went to work as usual. 2 The old man sat under the tree,______(listen) to the radio. 3________(turn) to the right,you will find the post office you’re lokking for. 4_________(find) her car stolen,she hurried to a policeman for help. 5 My computer______(repair),can I use yours for a while? 6________(finish) his homework,he went to bed. 7________(refuse) many times,I became desperate. 二；完成句子 1__________(把钥匙握在手上)，he looked for them everywhere.(hold) 2___________（天气允许的话），we’ll go on a travel.(permit) 3_____________(读完这本书)，he put it on the shelf.(finish) 4 It ___________(是星期天)，the street is very busy.(be) 5___________(还没完成)，the program still requires great efforts.(finish) 6____________(被带到医院) in time,the little girl was saved at last.(take) 7____________(聚集在火的周围)，the tourists danced with the local people.(gather) 8 The doctors are still working on the research,__________(希望找到)a cure for the disease.(hope)
