你好,我是世纪雅思的,很高兴为你解答:通过老师讲的,加上总结的和你分校一下:语法结构---- -ing 分词 -ING 分词也是动词的非限定性形式,由动词原形+-ING 构成,在句中可以直接作主语,也可用形式主语it 来代替,而把-ING 分词放到后边;可以作表语;作宾语时对动词有一定的要求,有的动词只能跟接-ING 分词,有的动词则既可以跟不定式也可以跟-ING 分词,而且-ING 分词还可作介词的宾语;在作宾语补足语时对动词也有一定的要求;作状语时,-ING 分词要与其逻辑主语呼应,否则就要用独立结构;-ING 分词作定语时相当于一个定语从句。跟动词不定式一样,-ING 分词也有它的完成时态、被动语态和否定形式;最后我们还要了解-ING 分词的逻辑主语问题。I -ING 分词的形式-ING 分词是指由动词原形+-ING 构成的、具有完成时态和被动语态的一种非谓语动词形式,具体形式如下主动形式被动形式一般时doing being done完成时having done having been done就其语法功能而言,它可以作主语、表语、宾语、宾语补语、状语和定语。II -ING 分词的用法一、作主语1. 一般形式1) _____________the matriculation for postgraduate is probably the turning point of my life.[A] Taking the part of[B] Taking part in[C] To take the part of[D] To take the notice in2)______________ a teacher is being present at the creation, when the clay begins to breathe.[A] As[B] To be[C] Is[D] Being3)_____________________ by transforming the blame to others is often called scapegoating.[A] Eliminate problems[B] The eliminated problems[C] Eliminating problems[D] Problems are eliminated2. 有时可以用it 做形式主语It's waste of time arguing with the gossip about it.It's interesting having traveled to Beidaihe this year.[说明:从这句中我们可以看出,这种结构通常适用于名词和形容词。但不适用于像possible, important, essential, necessary 等表示性质的形容词,这些词后面一般要跟动词不定式。我们不能说It's quite necessary taking part in the negociation.应改作It'squite necessary to take part in the negociation.]It's glorious getting involved in working out the plan.4) It is [A] possible determining that [B] French explorers reached the jucture of [C] the Kansasand Missouri rivers [D] in the seventeenth century.二、作表语的-ING 分词Seeing is believing.His aims are learning two foreign languages and applying the theory he has learned to practice.三、-ING 分词作动词宾语1. 一类是动词或短语后边跟宾语的非限定性动词只能是-ING 分词,如:acknowledge, admit(坦白,承认),advise, advocate, anticipate, appreciate, avoid, can't help, consider, contemplate(深思), delay, deny,dislike, enjoy, escape(躲过,避开), excuse, fancy, finish, give up, imagine, include, keep on, justify,mean(意味着,等于), mind(在乎), miss, postpone, practise, prohibit, put off, quit, recall, regret,resist, resume, risk(冒险干…), suggest, threaten。5) By taking the back way he escaped____________ .[A] to be seen[B] have been seen[C] seeing[D] being seen6) I came late and missed ________Jack winning.[A] to see[B] seeing[C] see[D] seen7) “I see our boss coming down the hall.”“Then we’d better quit___________ and get down to business.” …………如果你还需要学习资料,和我在QQ理说,我传给 你~~~
