一、情態(tài)動詞
情態(tài)動詞本身有一定的意義,但不能獨(dú)立作謂語,要和動詞原形一起構(gòu)成謂語,表說話人的語氣和態(tài)度。它沒有人稱和數(shù)的變化。常見的情態(tài)動詞有:
1. can表示能力,有“能”“會”的意思;表示可能性,多用在否定或疑問句中;表示請求和許可。
如:The parrot can speak three languages. 這只鸚鵡能講三種語言。
Can I borrow the book from the library?我可以從圖書棺借這本書嗎?
Shanghai can be very cold in March. 上海三月份可能會很冷。
拓展延伸can還有過去式could 可表“能,會”,又可以和be able to替換,而be able to有 更多時態(tài)。 如:
He could swim when he was four. =He was able to swim when he was four. 他四歲時就會游泳。 在一般疑問句中,can/could 常用來表示請求或征求對方意見,用could 比用can語氣更加委婉和客氣。類似用法的還有Will /Would you (please)…等句型。
如:Could you tell me how I can get to the post office? 你能告訴我怎樣到郵局嗎? Would you please turn up the radio?請你把收音機(jī)開大點(diǎn),好嗎?
2.may表示“許可”時,相當(dāng)于can,其否定回答用can’t/mustn’t;表推測時,常用在肯定句中,表“可能”。
如:-May I borrow your ruler?我可以借用您的直尺嗎?
-No, you can't /mustn't. 不行。
She may be a teacher. 她可能是一名教師。
拓展延伸may可表示祝愿。如: May you succeed! 祝你成功!
3.must表示“必須;必要”,以“must”開頭的一般疑問句其肯定回答用“must”,否定回答用“needn't”或“don't have to”。 must表推測時,常用在肯定句中,是“一定”的意思,其否定形式mustn ' t表“禁止”的意思。
如:-Must I leave now?現(xiàn)在我必須離開嗎?
-No,you needn't /you don't have to. 沒有必要。
This book must be Lucy's . Look! Her name is on the book cover. 這本書是露西的'?!封面上還有她的名字。
You mustn't draw on the wall. 你不準(zhǔn)在墻上畫畫。
拓展延伸must表示說話人的主觀看法,只有一般現(xiàn)在時;have to強(qiáng)調(diào)客觀要求,有時態(tài)、人稱和數(shù)的變化。如: My mother is ill. I have to look after her now. 媽媽病了,我得去照看她。
4.need作情態(tài)動詞時,常用在否定和疑問句中,表示“需要;要”的意思。
如:Need we finish the work now?現(xiàn)在我們需要完成這項(xiàng)工作嗎?
They needn ' t look after him. 他們不需要照顧他了。
拓展延伸need還可以用作行為動詞,可以用于各種句型。如:
Does he need any help? 他需要幫助嗎?
The desk needs repairing. 這張桌子需要修理。
5.shall 用于第一人稱,表示說話人征求對方意見,過去式為should;will 用手第二人稱的疑問句中,表示說話人向?qū)Ψ教岢稣埱蠛徒ㄗh,過去式為would。
如:Shall I go shopping with you?'我可以同你去購物嗎?
I don't know what I should do next. 我不知道下一步該干什么。
Would you please come a little earlier?請你來早一點(diǎn)好嗎?
6.情態(tài)動詞had better的用法
(1)had better 后接動詞原形,表勸告、建議,意為“最好”。“You'd better… ”含有強(qiáng)制命令的語氣,對長輩不宜使用。
如:You'd better ask that policeman over there. 你最好問一下那邊的那個警察。
(2)慎用had better! 注意以下四條:
、賖ad better表達(dá)的是說話者強(qiáng)硬性的建議,告誡別人(包括自己)如何做。 如:Granny, the hospital is not very near. We'd better catch a bus. 奶奶,醫(yī)院不是很近。我們最好坐公共汽車。
②had better不用于禮貌的請求或征詢,它隱含一種警告或威脅。 如:You ' d better finish the work today and bring it tomorrow. 你最好今天就把作業(yè)完成,明天帶來。
③had better意思接近should,但它除了表示語氣強(qiáng)硬以外,還表示馬上要去做的事情,比should更緊迫。 如:You’d better see a doctor at once. 你最好馬上去看醫(yī)生。
④had better不含比較的意思,該結(jié)構(gòu)表示“It would be good to… ”,而不是“It would be better to…”。
二、系動詞
系動詞有實(shí)際意義,但不能單獨(dú)做謂語,必須與表語一起構(gòu)成句子的謂語,說明主語的性質(zhì)、狀態(tài)或身份等。 它分為完全系動詞和不完全系動詞。
1.完全系動詞(be)可接名詞、代詞、形容詞、副詞、介詞短語、非謂語動詞短語、句子做表語。如: I'm a student. 我是個學(xué)生。(名詞) He is fine. 他很好。(形容詞) It is me. 是我。(代詞) Are you there?你在那兒嗎?(副詞) She is at school. 她在學(xué)校讀書。(介詞短語) He is to come soon. 他過會兒該來了。(不定式) My job is teaching English. 我的工作是教英語。(動詞的ing形式) My idea is that we will start now. 我的`想法是我們現(xiàn)在就開始。(句子)
2.不完全系動詞 (get,turn,feel,smell,look,sound,taste)一般只接形容詞做表語。如:When spring comes, it gets warmer and warmer.
春天來了,天氣變得越來越暖和了。 Food may go bad soon if it is not put into a fridge.
食物如果不放進(jìn)冰箱里就會很快變壞。 My brother became / turned a teacher after his graduation.
我哥哥畢業(yè)后就當(dāng)上了老師。(注意become和turn的用法區(qū)別)
