湖南省長沙市麓山國際學校英語九年級英語復習情態(tài)動詞素材

1、 情態(tài)動詞情態(tài)動詞數(shù)量不多，但用處廣泛，初中考點主要有：cancould, maymight, must, need, shallshould, willwould。情態(tài)動詞的特征：情態(tài)動詞本身有詞義但不能單獨作謂語，情態(tài)動詞+行為動詞原形 一起構成謂語。情態(tài)動詞不受主語的人稱和數(shù)的限制，不隨人稱和數(shù)的改變。情態(tài)動詞后可直接+not 構成否認，可放于句首構成一般疑問。1can和could的用法cancould表示 = 1 * GB3 “才能、 I can play the guitar. = 2 * GB3 “答應you can go now. = 3 * GB3 “可能性Lucy may b

2、e here.等。could 為 can 的過去式。 = 4 * GB3 表示懇求時，could比can更婉轉屬于如今時態(tài)范圍。如：Can I use your bike？我可以用你的自行車嗎？ 注意 can 和could 只能用于如今時和過去時兩種時態(tài)，將來時中用 be able to，be able to 所用的時態(tài)比can、 could廣。另外 cant 可表示否認推測“不可能。如：That _ be Mr Wang. He has gone to Beijing. 那肯定不是王老師，他已經去北京了。2may和might的用法maymight意為 = 1 * GB3 “可以，表示說話人同

3、意、答應或懇求對方答應May I use your pen?， = 2 * GB3 也可表示祝愿。 May god bless you! = 3 * GB3 may表允許用于肯定句中 You may go now. may的否認式為 may not。 might 是may 的過去式，有兩種用法：一種表示過去式；一種表示虛擬語氣，使語氣更加委婉、客氣，或表示可能性更小。如：_ I use your pen? 我可以用你的鋼筆嗎？You may put on more clothes. 你可以多穿衣服。 May you be happy.祝你開心。Might I borrow some money

4、 now?我如今可以借點錢嗎？ He might be alive. 他可能還活著。May 和might 表推測，比較小的不太有把握的推測。用于肯定句中。He may come tomorrow, but Im not sure.注意：may構成的一般疑問句防止用yes，you may.以免顯得不客氣。May I go now? _ Yes, please./ Please dont. / 否認No, you cant.3must的用法must = 1 * GB3 意為“必須，應該，一定，準是，表示說話人認為有必要做某事，命令、要求別人做某事以及對事物的推測。must 用于一般如今時和一般將來

5、時，過去式可用 have to 的過去式代替。如：I _ finish my work today.我今天必須完成我的工作。 = 2 * GB3 否認式mustnt表“嚴禁、制止 含義。You mustnt drive after drinking.你絕不能酒后駕車。1must 和 have to 的區(qū)別： must 表示說話人的主觀意愿；have to 表示客觀需要have to 的否認形式和疑問式要借助助動詞do。如：I must do my homework first.我必須首先做家庭作業(yè)。It is raining hard outside; I _ stay at home.外面雨

6、下得很大，我不得不待在家里。2答復must 的提問肯定答復：Yes，must.如：Must I go home now? Yes, you must.“我必須如今回家嗎？ “是的，你必須。否認答復：No，neednt./No，dont/doesnt have to.如：Must I go home now？ No, you _.“我必須如今回家嗎？ “不，沒必要。3must 可以表示肯定推測，意為“一定。比may 的可能性大如：The man must be our teacher.那個人一定是我們的老師。4need的用法1need 表示“需要，必須。主要用于否認句和疑問句中，否認形式為nee

7、dnt，表示“沒有必要，不必；need 提問時，肯定答復用must，否認答復用 neednt。如：Need we do some cleaning now? “我們必須如今大掃除嗎？Yes, you must. “是的，你們必須。 No, you neednt. “不，你們不必。2need 還可當做實義動詞使用，這時常用構造為need sth/ need to do sth。常用于肯定句中。否認形式和疑問式要借助助動詞do的形式。如：I need to learn more. 我需要學習更多。 5shall和should的用法shall 用于第一人稱的句子中表示提建議或懇求；建議和懇求為考點

8、should用于各種人稱的句子中強調義務或責任“應該。如：_ we go out for a walk? 我們出去漫步好嗎？建議You should study hard at school. 你們在學校應該努力學習。勸告6will和would的用法Will = 1 * GB3 情態(tài)動詞，用于第二人稱疑問句時，表示征求意見或提建議。 = 2 * GB3 助動詞 構成一般將來時。would 為 will 的過去式，可用于多種人稱， = 1 * GB3 表示意愿。如：Will you have a little soup?你要不要喝點湯？ = 2 * GB3 would you like sth/

9、to do sth?提出建議與懇求。此外還有情態(tài)動詞：had better, ought to , have to等等。歸納 情態(tài)動詞表推測的用法1肯定句中一般用must一定，may可能，might/could也許，或許，其中must表推測的語氣最強，其余依次漸弱。如：The book must be hers. Her name is on it.這本書一定是她的，她的名字在上面。He must be running.他一定是在跑步。They may know the way to the library.他們可能知道去圖書館的路。2否認句中一般用cant/couldnt不可能。如：That

10、 man cant be Mr Li because he has gone to London.那個人不可能是李老師，因為他去倫敦了。3疑問句中用can/could能。如：Can the red sweater be Toms?No, it cant. He cant stand red.“這件紅毛衣會是吉姆的嗎？“不，不可能。他不能忍受紅色。注意 might, could并不是may, can的過去式，而是表示語氣較委婉或可能性較小。 = 4 * GB2 情態(tài)動詞+一般如今時/do 表示對如今發(fā)生的事情的推測。如：Whose book is this? It must belong to

11、Lucy. 它一定屬于露西的。情態(tài)動詞+進展時/be doing 表示對如今正在發(fā)生的事情的推測。如：He must be sleeping now.如今他一定正在睡覺。情態(tài)動詞+完成時 have done表示對已經過去發(fā)生的事情的推測。如：Our classroom is very clean.
