Module4 Sandstorms in Asia –Grammar學案

infinitive一、教學目標：1、掌握動詞不定式在句中的基本用法以及動詞不定式的時態和語態，2、掌握常用動詞不定式作賓語或賓補的常見的動詞或句型；二、自學導引：1、課前預習和歸納動詞不定式的用法以及動詞不定式的時態和語態時態（結合課本p107）2、課前完成本學案中學案上的練習并討論合作探究部分，對其作一歸納。合作探究：小組討論并歸納其考點1. ____ is believing.  a. to see b. seeing c. see  d. to be seen2. when i handed the report to john, he said that george was the person ____. a. to send b. for sending it c. to send it to d. for sending it to3. she didn’t remember_____ him before.a. having met b. have met c. to meet d. to having met4. there isn’t any difference between the two. i really don’t know _________. a. where to choose b. which to choose c. to choose what d. to choose which5. mrs smith warned her daughter ________ after drinking. a. never to drive b. to never drive c. never driving d. never drive6. though he had often made his little sister _____, today he was made _____by his little sister.   a. cry；to cry b. crying；crying c. cry；cry d. to cry；cry 教師點撥：動詞不定式具有動詞特點，可以有自己的賓語和狀語，組成動詞不定式短語。動詞不定式的肯定形式是to＋do；其否定形式是not to＋do。完成式：to+ have done；進行式：to+ be doing。具體用法：　1、作主語　 to see is to believe.　但在英語中，常用it作形式主語，真正的主語即動詞不定式放在后面。如：　　it's wrong to play tricks on other people.　　2、作賓語    不定式作賓語有兩種：一種是及物動詞后直接跟帶to的不定式，另一種是“及物動詞+疑問句+帶to 的不定式”。    1）及物動詞+帶to的不定式結構：    只能跟動詞不定式的動詞，常見的有：want, wish afford, agree, aim, appear, ask, decide, demand, desire, determine, expect, , happen, hope, intend, manage, offer, pretend, promise, prepare, refuse, seek, t, undertake等。    he managed to solve the complicated problem    the stranger offered to show me the way.    mr. smith undertook to build a new plant in south africa.    2）動詞+疑問代（副）詞+不定式：常見的動詞有：advise, decide, discuss, find out,, know, learn, regard, remember, see, teach, tell, understand,等。常用的疑問代（副）詞有what, when, where, which, how, whether等，但不包括why。     he does not know when to start.       i will show you how to deal with it.    有時，不定式可由it代替，而把不定式放到后面去。這可以用這一結構表達：動詞（如find, think, consider, feel等）+it+形容詞+不定式，it是形式賓語，真正的賓語是后面的動詞不定式。
