4、favourite sport. fishing是一个动名词，由动词+ing组成，动名词可以作主语或宾语，如eating，reading等等 fish n. 鱼（不可数名词），鱼的种类（可数） There are a lot of fishes(表示种类)in the sea. v. 钓鱼, 捕鱼 2、I often fish for hours without catching anything. for+时间 表示一段时间 for hours=for some hours 数小时 without catching anything作为状语而出现, 表示结果状语。without 是介词，后面

5、一定要加宾语, 动名词catching作 without 的宾语，without 后面的动作是主语来做的。动名词也有动词的特性，可以有自己的宾语。 without通常表示“缺乏、没有”；当它位于动名词前时，表示“不曾、不” I cant repair the car without your help. They tried to leave the restaurant without paying. He went out without saying any words. 3、But this does not worry me. worry v. 烦恼，担扰 worry sb. 某人为

6、烦恼，担扰（作动词一定要加人作宾语, 翻译时从后往前翻，宾语担心） The house worried me. / My daughter worried me. adj. 担心 be worried about 为担心 I was never worried about this. = This does not worry me. 4、Instead of catching fish, they catch old boots and rubbish. instead of 我原准备做但是后来做了（instead of 后面的词一定是没有做的, 可以放在主句后面） I went to sc

7、hool instead of staying at home. 我没呆在家里而是去上学了 I bought books instead of buying dresses. without强调没有做某件事, instead of强调这件事没做成而做成了另外一件事 副词instead“作为替代，反而”，单独使用时一般出现在句尾 If you dont want a holiday in England, why dont you go to Australia instead? 5、I am even less lucky. less是little的比较级，意为“不及，不如，更少” I spe

8、nd less time on English than on French. less+原形 A is lessthan B A不如B 6、After having spent whole mornings on the river, I always go home with an empty bag. spend+时间+在某地 在某地度过时间 after <conj.>+从句 在之后 after <prep.>+名词/动词的ing形式 之后（从句主语必须是主句的主语时两种形式可互换） After I go to school, I learned a lot of

9、 knowledge. (用一般式表示一个事实, 不用 “went to” ) After going to school, I learned a lot of knowledge. 介词after的宾语的动名词having spent所表示的动作发生在谓语动词go之前，所以动名词用完成形式。 with an empty bag 注意连读 with sth. 有的，持有的，随身带着(状语) Whos the man with the beard? without sth. 没带 I always go home without angthing. 什么都没带回家 7、'You mus

10、t give up fishing!' my friends say. give up doing sth. = stop doing sth. 放弃做某事 Give up smoking. 8、I'm not really interested in fishing. be intersted in sth. / doing sth. 对感兴趣 Im interested in collecting stamps. 三、语法动名词 动词+ing 作名词时称为动名词，它仍有动词的属性，可以接宾语，动名词可以代替名词做主语和宾语或介词宾语。 1、动名词作主语 Watching t

I must apologize for interrupting

12、you. 由于打断了你的说话(工作), 我得表示道歉. （for interrupting强调interrupt这个动词） I must apologize for having interrupted you.（for having interrupted强调interrupt这个动词先发生，强调时间 (having done)）以上两者为时间概念不同，意思相同 congratulate (sb.) on doing sth. 因祝贺（某人） He congratulated me. I won the competition. 他向我道贺. 我赢得了这次比赛. He congratulat

13、ed me on winning the competition. 在我赢得这次比赛之际, 他向我祝贺. He congratulated me on having won the competition. thank you for listening/attending 动名词用表示完成时的 having+过去分词结构往往强调动名词的动词发生在前面。 4、跟动名词的短语 be keen on doing sth.（热忠于）,be fond of,be interested in,enjoy doing sth.（喜欢做某事），congratulations on doing sth. （祝

14、贺） be afraid of be up to=be capable of (capable adj.有能力的, 能干的, 有可能的, 可以.的) 可以带动名词的介词有：before，after，without，instead of等 I cant watch TV without falling asleep. 我看电视时必定会睡着。 5、动名词的否定式是在它前面直接加not。 Exercises C(用括号中的词来连接下列句子, 如需要可对原句进行必要的改动) 2.She bought a pair of boots.
