3. doing与to do在动词后面做宾语的区别二. 知识总结归纳：（一）动词ing形式起名词作用，在语法中也称做动名词．在句中做主语，宾语，表语和定语。
它的基本形式有doing; being done。
例句：1. Parking is difficult in the shopping center of the city.2. My favorite job is teaching English.3. His main hobby is collecting stamps.4. Denying this will be shutting one’s eyes to fact.5. I suggest you should practise speaking English whenever you can.6. Hearing what I said, h e couldn’t help laughing.7. Did you see that car being repaired ?注：to do形式也可以做主语或表语。
一般情况下，这两种形式做主语或表语，差别不是很大。
但是如果刻意强调某个具体的动作，就用to do 形式，而要表示一般性或泛指的动作则用doing形式。
例如：1. It is difficult to park in the shopping center at the weekend.2. My duty is to take care of the baby while she is out.（二）在一些动词后面只能接动名词做宾语。
后面跟doing做宾语的常见动词有：admit; advise; appreciate; avoid; complete; consider; deny; mention; mind; miss; prevent; delay; enjoy; escape; imagine; postpone; practise; risk; suggest;常见的动名词短语，如：be worth doing; c an’t help doing; look forward to doing; go on doing; insist on doing; prefer doing to doing; be busy doing; keep on doing; devote…to doing; spend…in doing; have difficulty in doing; have a good time doing; prevent…from doing1.

He insisted on sending for doctor at once.6. The film is well worth seeing.7. You can’t imagine the difficulty we had making a little money.（三）doing形式的逻辑主语：当强调doing所表达的动作的执行者（逻辑主语）时，需要在doing前面加上物主代词，人称代词宾格，名词所有格或不定代词例句：1. I’m surprised at your/you doing it.2. She insisted on their both accepting the invitation.3. Do you mind my opening the window ?4. Your being right doesn’t necessarily mean my being wrong.5. The children are looking forward to spring coming.6. He disapproved of that being said about Jane.7.

动词ing形式的用法及变化规则动词ing形式的用法及变化规则一．动词ing形式的用法1.正在进行时中,谓语动词后加ing. 如:I'm playing football.2.一些特殊表达..如: be good at doing sthenjoy doing sth.be busy doingfeel like doingthank you for doingdo some cooking/cleaning/reading/shopping/washinggo swimming/fishing/shopping/skating/boating二．动词现在分词由动词原形在词尾加ing构成，其规则如下：1）一般情况下直接加ing think---thinking sleep---sleeping study---studying speak---speakingcarry---carrying say---saying2）以不发音的字母e结尾的单词，去掉字母e，再加ingwake---waking make---making come---comingtake---taking leave---leaving have---having3）以重读闭音节结尾，呈现“辅，元，辅”结构的动词，先双写末尾的辅音字母，再加ing 。
初中学过的这类词有：begin，cut, get, hit, run, set, sit, spit, stop, swim, beg, drop, fit, nod, dig, forget, regret, rid, 等。
(visit 不是以重读闭音节结尾，不用双写)travel虽然重读第一音节，词尾音节不重读，但是现在分词仍要双写末尾辅音字母，然后再加ing ，如：travel---travelling.初中阶段此类词只有这一个。
4）以 y 结尾的动词直接加 ingcarry—— carrying enjoy—— enjoying5）以ie结尾的动词，把ie改为y ，再加ingdie---dying lie---lying要特别注意有些动词没有进行时态.1、表示状态、思想、感情和感觉的动词，如：see, hear, love, know, want, hope, think等，没有进行时态。
动词ing形式知识点总结一、动词的ing形式的构成动词的ing形式一般是在动词原形的基础上加上-ing后缀来构成的。
例如：walk → walkingeat → eatingwrite → writing但是也有一些不规则的情况，如：go → goingrun → runningswim → swimming动词的ing形式可以作为动名词使用，表示动作或状态的进行或延续。
它还可以用作动词短语、现在分词或复合动词的一部分，具体用法将在接下来的内容中详细介绍。
二、动词的ing形式在进行时态中的用法1. 表示正在进行的动作动词的ing形式可以用于进行时态，表示正在进行的动作。
例如：He is reading a book.（他正在看书。
）She is writing an article.（她正在写一篇文章。
）They are playing basketball.（他们正在打篮球。
）2. 表示一段时间内延续进行的动作动词的ing形式也可以表示一段时间内延续进行的动作。
例如：I have been studying English for five years.（我已经学习英语五年了。
）She has been working here since last month.（她上个月就在这工作了。
）They have been living in this city for a long time.（他们在这座城市住了很长时间。
）3. 注意事项在进行时态中，be动词的形式（am/is/are）加上动词的ing形式构成句子的谓语部分。
同时，进行时态也对时间状语有一定的限制，表示正在进行的动作必须是在说话时或与说话时有关的时间内进行的。
例如：I am studying English.（表示正在进行的动作）I was studying English when he called.（表示过去正在进行的动作）三、动词的ing形式在现在分词和动词短语中的用法1. 作为现在分词使用动词的ing形式可以作为现在分词使用，充当形容词修饰名词或代词。
