钓鱼是我特别喜爱的一项运动。我经常一钓数小时却一无所获，但我从不为此烦恼。有些垂钓者就是不走运，他们往往鱼钓不到，却钓上来些旧靴子和垃圾。我的运气甚至还不及他们。我什么东西也未钓到过 — 就连旧靴子也没有。我总是在河上呆上整整一上午，然后空着袋子回家。“你可别再钓鱼了！”我的朋友们说，“这是浪费时间。”然而他们没有认识到重要的一点，我并不是真的对钓鱼有兴趣，我感兴趣的只是独坐孤舟，无所事事！
关键句型—动名词 ding---nt ding
1）是动词的一种非谓语形式；2）可带宾语起名词的作用，作主语，表语，动/介词宾语， 以及定语。）a.) Getting up early is a gd habit.b.) Fishing is Tm’s favrite hbby.c.) David is interested in driving.d)D yu mind turning n the TV?e.) My jb is testing all kinds f sftware.f.) Seeing is believing.g)a swimming pl
动名词作表语与不定式的区别： 动名词表示比较抽象的一般行为、习惯；不定式作表语时表示具体的某一次动作，特别是将来的动作， My favurite sprt is swimming. The first thing fr us t d is t imprve ur prnunciatin.It’s n use crying ver spilt milk. (抽象) He realized that t g n like this was n use. (具体)
用括号内动词的适当形式填空：
_______ (listen) t pp music is smething he enjys.The wrkers left after ________ (finish) the wrk.After __________________ (spend) the mney, he wrte t his father.Yu shuld aplgize t yur teacher fr ______ (cme) late.We can learn hw t write by ______ (read).Dn’t be afraid f ______ (ask) questins.Are yu interested in ______ (play) vlleyball?He left hme withut ______(lck) the dr.
having spent/spending
9._________ (teach) English is my des he enjy________ (walk) in rain?11.He aplgized fr _________ (nt hand) in the hmewrk n f ________ (g) t see a dctr, he lay in bed and had a sleep.13.I stayed in bed all day instead f ________ (g) t wrk.14.A lt f men have given up _________(wear) is very interested in ________ (dance) _______ (enter) the rm, he turned n the light.
V-ing 形式作主语 往往表示抽象、笼 统的动作。如： a.) Getting up early is a gd habit. b.) Fishing is Tm’s favrite hbby. c.) Crying ver spilt milk is n use. d.)Arguing with him is a waste f time.
注：动名词作主语与不定式作主语的区别： 动名词作主语通常表示抽象的或泛指的动作，一般不与特定的动作执行者联系在一起；不定式作主语通常表示具体的动作或行为，往往与特定的动作执行者联系在一起，如： It’s n use crying ver spilt milk. (抽象) He realized that t g n like this was n use. (具体) 在实际运用中，一般可以互换，差异不大。但在下列几种情况中不能互换： a. 当表语是动名词时，主语也要用动名词；当表语是不定式时，主语也要用不定式，如： Seeing is believing. T see is t believe.
b. 动名词和不定式作主语，一般都可以使用形式主语it，而将动名词或不定式放在句尾。但是在下列句型中，一般宜用动名词，不宜用不定式来代替： It’s n use ding … It’s n gd ding… It’s a waste f time ding …
例如： It’s n use ging there tday; he wn’t be at hme. It’s a waste f time arguing abut it.
而在It’s imprtant … / It’s necessary … / It’s advisable … / It’s essential … / It’s fitting … 这类句型中，只能用不定式，如： It’s imprtant t learn freign languages. It’s quite necessary t read it many times.
3) V-ing形式作表语 (放在系动词之后,泛指某种动作或行为,常用来说明主语的身份、内容或特点。)如：a.) My jb is testing all kinds f sftware.b.) The purpse f my letter is advising yu t d mre sprts.c.) His greatest happiness is serving the peple.d.) Seeing is believing.
注①：动名词作表语与不定式作表语的区别： 动名词作表语时表示比较抽象的一般行为、习惯；不定式作表语时表示具体的某一次动作，特别是将来的动作，试比较： My favurite sprt is swimming. The first thing fr us t d is t imprve ur prnunciatin.
注②：动名词作表语与现在分词作表语的区别： 动名词作表语时相当于名词，说明主语的含义及内容，它与主语是同等关系，主语与表语互换位置不影响句子的基本含义，但不可用副词来修饰。 现在分词作表语时相当于形容词，说明主语的特征、性质、状态等，主语与表语不可互换位置，但可用very, quite等副词来修饰，如： My jb is lking after the children. Our duty is serving the peple heart and sul. The situatin is encuraging. This cake is very inviting. The vlleyball match we watched was very exciting.
2) V-ing形式作宾语 a.) She sat there withut speaking. b.) David is interested in driving.c.) D yu mind turning n the TV? d.)Betty enjys listening t pp music.
★    能用动名词作宾语的动词有两类： 一类是只能用动名词作宾语的动词，其中有：avid, admit, cnsider, delay, advise, dislike, enjy, escape, excuse, mind等，如： Mary is cnsidering changing her jb. I enjy wrking with yu. Wuld yu mind ringing me up tmrrw? 另一类是既可以用动名词，又可以用不定式作宾语的动词，其中有：cntinue, frget, hate, intend, like, lve, plan, prefer, prpse, regret, remember, start, try, want, need, can’t affrd等。
B. 在need, want, deserve等后，可用动名词的主动式表示被动含义，或用不定式的被动式，意义上无差别。但用动名词较为普遍，（这时主语一般是物），如： The dr needs iling / t be iled. C. 有的动词尽管可以用两种结构，但意义明显不同，须认真加以区别： I frgt t clse the dr befre I left the rm. I frgt having clsed the dr. He tried t write better. (尽量努力地写) He tried writing with a brush. (用毛笔试着写) I culdn’t help finishing it. (不能不结束某事) I culdn’t help t finish it. (不能帮助结束某事) They left ff fishing. (停止钓鱼) They left ff t fish. (离开某处出发去钓鱼) I regret t say that there is n wine in the bttle. (对现在要发生的事表示遗憾、抱歉) I regret nt taking yur advice. (后悔)
在必要的地方用适当的介词填空。
I ften fish ______ hurs withut catching anything.What are yu interested _____ ?--- Where are yu ging? --- I’m ging _____ Jimmy’s _____ ging t schl, the by stayed at ’s a waste _____ time.
