听录音，然后背诵课文

钓鱼是我尤其喜爱一项运动。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早晨，然后空着袋子回家。“你可别再钓鱼了！”我朋友们说，“这是浪费时间。”然而他们没有认识到主要一点，我并不是真对钓鱼有兴趣，我感兴趣只是独坐孤舟，无所事事！Tellthestory:1.Fishing—favouriteaport2.often—hours—anything3.some—unlucky4.Instead—fish—boots—rubbish5.I—less6.never—even—boots7.wholemornings—river—home—empty8.‘giveup’—friends—‘waste—’9.don’trealize—importantthing10.only—sitting—nothing关键句型—动名词1）动名词是动词一个非谓语形式；2）v.+ing形式;3)它在句中其名词作用，可单独或引发短语作主语，表语，动词宾语，或介词宾语以及定语。）

V-ing形式作主语往往表示抽象、笼统动作或泛指某动作或行为。如：

a.)Gettingupearlyisagoodhabit. b.)FishingisTom’sfavoritehobby. c.)Cryingoverspiltmilkisnouse. d.)Arguingwithhimisawasteoftime.Subject注：动名词作主语与不定式作主语区分：

动名词作主语通常表示抽象或泛指动作，普通不与特定动作执行者联络在一起；不定式作主语通常表示详细动作或行为，往往与特定动作执行者联络在一起，如：It’snousecryingoverspiltmilk.(抽象)Herealizedthattogoonlikethiswasnouse.(详细)

在实际利用中，普通能够交换，差异不大。但在以下几个情况中不能交换：

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：Seeingisbelieving.Toseeistobelieve.b.动名词和不定式作主语，普通都能够使用形式主语it，而将动名词或不定式放在句尾。不过在以下句型中，普通宜用动名词，不宜用不定式来代替：It’snousedoing…It’snogooddoing…It’sawasteoftimedoing…比如：It’snousegoingtheretoday;hewon’tbeathome.It’sawasteoftimearguingaboutit.

而在It’simportant…/It’snecessary…/It’sadvisable…/It’sessential…/It’sfitting…这类句型中，只能用不定式，如：It’simportanttolearnforeignlanguages.It’squitenecessarytoreaditmanytimes.3)V-ing形式作表语(放在系动词之后,泛指某种动作或行为,惯用来说明主语身份、内容或特点。)如：a.)Myjobistestingallkindsofsoftware.b.)Thepurposeofmyletteris

advisingyoutodomoresports.c.)Hisgreatesthappinessisservingthepeople.d.)Seeingis

believing.Predictive注①：动名词作表语与不定式作表语区分：动名词作表语时表示比较抽象普通行为、习惯；不定式作表语时表示详细某一次动作，尤其是未来动作，试比较：Myfavouritesportisswimming.Thefirstthingforustodoistoimproveourpronunciation.注②：动名词作表语与现在分词作表语区分：

动名词作表语时相当于名词，说明主语含义及内容，它与主语是同等关系，主语与表语交换位置不影响句子基本含义，但不可用副词来修饰。现在分词作表语时相当于形容词，说明主语特征、性质、状态等，主语与表语不可交换位置，但可用very,quite等副词来修饰，如：Myjobislookingafterthechildren.Ourdutyisservingthepeopleheartandsoul.Thesituationisencouraging.Thiscakeisveryinviting.Thevolleyballmatchwewatchedwasveryexciting.2)V-ing形式作宾语

a.)Shesattherewithoutspeaking. b.)Davidisinterestedindriving.

c.)DoyoumindturningontheTV? d.)Bettyenjoyslisteningtopopmusic.Object★

能用动名词作宾语动词有两类：一类是只能用动名词作宾语动词，其中有：avoid,admit,consider,delay,advise,dislike,enjoy,escape,excuse,mind等，如：Maryisconsideringchangingherjob.Ienjoyworkingwithyou.Wouldyoumindringingmeuptomorrow?另一类是既能够用动名词，又能够用不定式作宾语动词，其中有：continue,forget,hate,intend,like,love,plan,prefer,propose,regret,remember,start,try,want,need,can’tafford等。

B.

在need,want,deserve等后，可用动名词主动式表示被动含义，或用不定式被动式，意义上无差异。但用动名词较为普遍，（这时主语普通是物），如：Thedoorneedsoiling/tobeoiled.

C.

有动词尽管能够用两种结构，但意义显著不一样，须认真加以区分：IforgottoclosethedoorbeforeIlefttheroom.

Iforgothavingclosedthedoor.

Hetriedtowritebetter.(尽可能努力地写)

Hetriedwritingwithabrush.(用毛笔试着写)

Icouldn’thelpfinishingit.(不能不结束某事)

Icouldn’thelptofinishit.(不能帮助结束某事)Theyleftofffishing.(停顿钓鱼)Theyleftofftofish.(离开某处出发去钓鱼)Iregrettosaythatthereisnowineinthebottle.(对现在要发生事表示遗憾、抱歉)Iregretnottakingyouradvice.(后悔)练习题：用括号内动词适当形式填空：_______(listen)topopmusicissomethingheenjoys.Theworkersleftafter________(finish)thework.After__________________(spend)themoney,hewrotetohisfather.Youshouldapologizetoyourteacherfor______(come)late.Wecanlearnhowtowriteby______(read).Don’tbeafraidof______(ask)questions.Areyouinterestedin______(play)volleyball?Helefthomewithout______(lock)thedoor.Listeningfinishinghavingspent/spend
