动词ing形式作宾语补足语、状语
一、动词ing形式作宾语补足语
1.表示感觉和心理状态的感官动词(短语)(常见的有see, hear, feel, smell, find, notice, observe, look at, listen to等)+sb.+doing sth.(作宾补)。
动词 ing形式作宾语补足语时,表示正在进行的动作或经常存在的状态。动词 ing形式常作以下动词的宾语补足语。
I saw the little boy crying there.我看到小男孩在那儿哭。
Step 3 Learn about v+ing carefully
使役动词接现在分词作宾语补足语表示“让……一直做某事”。接不带to的不定式作宾语补足语表示“让某人做某事”;接过去分词作宾语补足语,表示“主语请某人做某事,使完成某事或主语遭遇某事”。
名师点津
2.表示指使意义的使役动词(常见的有have, let, keep, get, leave等)+sb./sth.+doing sth.(作宾补)。
We kept the fire burning all night long.我们让火整夜燃烧着。
I won’t have you running about in the room.我不允许你在房间里跑来跑去。
3.用于with复合结构中。
I couldn’t do my homework with the noise going on.
由于噪音不断,我没法做家庭作业。
With so many people looking at her, she felt nervous.
这么多人看着她,她感到紧张。
二、动词ing作状语
动名词和现在分词都可以作定语,但有所区别。
名师点津
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。
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 old friend.
=When/While (she was) walking in the park, she saw an old friend.
当她在公园里散步时,她看到了她的一个老朋友。
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 couldn’t go to school.
=As he was ill, he couldn’t go to school.
因为生病了,他无法去上学。
You should adapt to the changing situation.
你应该适应不断变化的形势。
The ground is covered with fallen leaves.地上满是落叶。
I’m looking for a room to live in.我正在找房子住。
3.作条件状语(一般放在句首,其前可以加if, unless等连词)
Working hard, you’ll make great progress.
=If you work hard, you’ll make great progress.
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 plate dropped from her hands, breaking into pieces.
盘子从她手中掉了下来,摔成了碎片。
名师点津
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only。
试比较:
He was caught in the rain, thus making himself catch cold.
被雨淋后他感冒了。
I hurried to school, only to 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 window of the classroom, reading a book.
=Mary sat by the window of the classroom and was reading a book.
玛丽坐在教室的窗边读一本书。
名师点津
为强调动词 ing形式表达的意义,可在其前加上各种连词。例如,加上when, while,强调与谓语动词同时发生;加上before, after,强调动作先后发生;加上thus,强调结果;加上(al)though,强调让步等。
Though knowing all this, they made me pay for the damage.
尽管他们了解这一切,但还是让我赔偿损失。
三、现在分词作状语注意事项
1.现在分词的时态
现在分词作状语时,要注意分词的时间性,是用现在分词的一般式(doing),还是用完成式(having done)。
(1)当现在分词的动作与谓语动词的动作同时发生时,用分词的一般式。
Walking in the street, I met an old friend of mine.
我正在大街上行走时,遇到了一位老朋友。(walking和谓语动词met同时发生)
(2)当现在分词的动作先发生,而谓语动词的动作后发生时,用分词的完成式。
Having finished the letter, he went to post it.
他写完信后就把它寄了出去。(having finished是先发生的,went是后发生的)
2.现在分词的语态
使用现在分词的主动式还是被动式,这主要取决于现在分词和句子主语之间的关系。句子的主语就是分词的逻辑主语。
Having been shown around the factory, they were very happy.(现在分词的被动式)
被领着参观了工厂后,他们很高兴。
Having finished his homework, he went to bed.(现在分词的主动式)
完成了作业后,他上床睡觉。
3.动词 ing形式的否定式:not+v. ing; not having+v. ed
Not knowing this, he didn’t come.
他不知道这件事,所以没来。
Not having made full preparations,we put off the sports meeting.
因为没有做好充分的准备,我们把运动会延期了。
Step 4 Complete the passage with the underline sentences that using v+ ing form
1. How do you use the function of -ing
2. What’s the difference between -ing
