【探究总结】(1) 常接动词-ing形式作宾语的动词有:(口诀)避免错过少延期(avid,miss,pstpne)建议完成多练习(advise/suggest,finish,practise)喜欢想象禁不住(enjy,imagine,can’t help)承认否定与嫉妒(admit,deny,envy)逃避冒险莫原谅(escape,risk,excuse)忍受保持不介意(stand,keep,mind)
(2) 常见t作介词的短语:献身于 devte neself t期待做某事 lk frward t反对 bject t 习惯于 be used/accustmed t导致 lead t坚持 insist n/stick t注意 pay attentin t着手做某事 get dwn t做某事的方法 the apprach t ding

三、现在分词作状语的用法现在分词(短语)在句中作状语来修饰谓语动词或整个句子,表示动作发生的时间、原因、条件、结果、方式、让步或伴随状况。1.作时间状语(相当于一个时间状语从句)。 Walking in the park,she saw an ld friend.=When/While (she was) walking in the park,she saw an ld friend.当她在公园里散步时,她看到了她的一个老朋友。注意:当表示正在进行的动作时,可直接在分词前面加上when/while,此时也可理解为状语从句的省略。
2.作原因状语(一般可转换成由as或because引导的原因状语从句)Being ill,he culdn’t g t schl.=As he was ill,he culdn’t g t schl.因为生病了,他无法去上学。3.作条件状语(一般放在句首,可转换成由if,unless等连词引导的条件状语从句)Wrking hard,yu’ll make great prgress.=If yu wrk hard,yu’ll make great prgress.如果你努力工作,你将取得很大进步。
4.作结果状语现在分词作结果状语时,通常放在句末,中间用逗号隔开,表示一种顺其自然、意料之中的结果。The hspital has recently btained new medical equipment,allwing mre patients t be treated.这家医院最近得到一批新的医疗设备,这使更多的病人能得到治疗。注意:现在分词作结果状语,是随着谓语动词的发生而产生的自然结果,其逻辑主语往往是前面整个句子所描述的情况,前面有时候可以加thus。而不定式作结果状语时常表示出乎意料的结果,有时前面可以加nly。试比较:He was caught in the rain,thus making himself catch a cld.被雨淋后他感冒了。
I hurried t schl,nly t find it was Sunday.我匆忙赶到学校,结果发现是星期天。5.作让步、方式和伴随状语现在分词作让步、方式和伴随状语时,说明动作发生的背景和情况。作伴随状语时,表示分词的动作和主句的动作同时发生,此时它可转换成并列句。Mary sat by the windw f the classrm,reading a bk.=Mary sat by the windw f the classrm and was reading a bk.玛丽坐在教室的窗边读一本书。
1. ___________ the curse difficult, she decided t mve t a lwer level. [find]2. ___________ in the street, I came acrss an ld friend f mine. [walk]3. ________ the news, she burst int tears. [hear]4. _______ in the early 20th century, the schl still lks still in a gd shape. [fund]5. _______ in English, the bk is easy t read. [write]
-ing表示和主语主动关系-ed表示和主语被动关系
6. ______ afraid, she keeps lking arund. [feel]7._______________ many times, he finally understd it.[tell] 8. _______________ the hmewrk, she left the classrm and went t the playgrund. [finish]9. __________________ the hmewrk, she had t stay in the classrm. [ nt finish]
Having been tld
Having finished
Nt having finished
-ing表示和句子的谓语动词(几乎)同时发生,或之后having dne表示先于谓语动词发生
作结果状语:(意料中的结果) ① The hunters fired, _________(sht) ne f the wlves. ②The bus was held up by the snwstrm, thus _________ (cause) the delay. 区别: 不定式表示意外的结果 He hurried t the statin, nly ________ (find) the train had left. 作让步状语: ①Thugh it heavily rained heavily, it cleared up very sn. = ________________, it cleared up very sn. ②Thugh _____ (tell) f the danger, he still risked his life t save the by.
Raining heavily
四、动词-ing形式作表语,说明主语____________________。 eg Our jb is playing all kinds f music. = Playing all kinds f music is ur jb. The music they are playing sunds s exciting.
动词-ing形式表名词的特性,主语和表语可以互换。
动词-ing形式有形容词的特性,表示主语的性质和特征,主语和表语不可互换。
注意:1.不定式和动词-ed形式也可作表语,但不定式通常强调一次性的、具体的、将要发生的动作,动词-ed形式则表示被动、完成含义。2.动名词作表语多表示抽象性的或习惯性的动作,一般说明主语的内容。Her jb is keeping the lecture hall as clean as pssible.=Keeping the lecture hall as clean as pssible is her jb.她的工作是尽量使报告厅保持干净。
My jb is __________ (prmte) the new prduct.My dream is __________ (be) a dctrHis jb is ___________________ (cllect) flk sngs. The spy stry was __________ (thrill). He was __________ (thrill) at the idea.
t prmte/prmting
t cllect/cllecting
t d 说明主语内容,具体、特定、未来ding 说明主语内容,一般或习惯ding adj. 说明主语的特征,令人…的dne adj. 说明主语的感受或状态,感到…的
【探究总结】(1) 动词-ing形式作定语置于名词前有两种情况:一种是表示被修饰名词的某种 ,另一种是表示被修饰名词 的状态或动作。(2) 动词-ing短语作定语时要在所修饰名词的 。
【观察思考】N ne is allwed t speak alud in the reading rm. Can yu see the swimming pl? The girl swimming there is his daughter.
五、动词-ing形式作定语
注意:现在分词、过去分词和不定式作定语的一般区别:现在分词表示正在进行或习惯性的动作;过去分词表示被动或完成意义;不定式表示动作尚未发生。Yu shuld adapt t the changing situatin.你应该适应不断变化的形势。The grund is cvered with fallen leaves.地上满是落叶。I’m lking fr a rm t live in.我正在找房子住。

六、动词-ing形式作宾语补足语 I felt smebdy standing behind me. I saw the little by crying there. I heard her lcking the dr. We kept the fire burning all night lng. I wn’t have yu running abut in the rm.
【探究总结】(1) 表示感觉和心理状态的感官动词(短语)(see,hear,feel,smell,find,ntice,bserve,lk at,listen t等)后面的宾语和宾语补足语之间表示 、 的动作或经常存在的状态,用 作宾语补足语。(2) 表示指使意义的使役动词(常见的有have,let,keep,get,leave等),接动词-ing作宾语补足语表示“ ”。
