*e
一、so do I、so am I 也就是so +be/助動詞/情態動詞這樣的句型可以用來表示“某人也一樣”,用在前面敘述的情況與某人也相符時.eg.1,---I like pop music.我喜歡流行樂---so do I.我也喜歡.因為此時like是實意動詞,選用do或者does,若此時主語是第三人稱,要用does,如so does lily.如果是過去式,用did.完成時則根據第一句話的時態和第二句的主語選用have,has/had2,---I am a movie fan.我是個電影迷 ---so am I.我也是 還可以說So is he/she.同理,可以使用so are you/ so was he/so were they等二、so+主語+be/助動詞/情態動詞這種結構用于表示“的確如此”,用來肯定別人的話.eg.----He is a brave man.他是個勇敢的人 ---so he is.是啊/的確如此----He has won the first prize in the English speaking contest.---so he has.。

6.情態動詞表推測
表示推測的有順序的
從可能性最大到最小是這樣排的:
must——may——might——not

情態動詞表推測的用法小結
(一)情態動詞表推測的三種句式
1.在肯定句中一般用must (一定),can,could(可能),might /may(也許,或許)。
* must/can/may,might knowthe answer to this question.
他一定/可能/也許知道這個問題的答案。
* is cold in the room. Theymust have turned off the heating.
屋里很冷,他們肯定把暖氣關了。
2.否定句中用can't / couldn't(不可能),may not/might not(可能不)。
* can't/couldn't be the
headmaster. He has gone to America.
這不可能是校長,他去美國了。
* may not/might not know thescientist.
他也許不認識那位科學家。
3.疑問句中用can/could (能……?)。
* he have finished thetask?
他可能把任務完成了嗎?
* he be at home now?
他現在能在家嗎?
注:以上三種句式中情態動詞的語氣按程度都是依次遞減的。Might,could并非may,can的過去式,而表示語氣較為委婉或可能性較小。
7.什么是情態動詞
情態動詞的定義: 情態動詞是一種本身有一定的詞義,表示說話人的情緒,態度或語氣的動詞,但不能單獨作謂語, 只能和其他動詞原形構成謂語。
We can be there on time tomorrow. 我們明天能按時去那兒。 May I have your name? 我能知道你的名字嗎? Shall we begin now? 我們現在就開始嗎? You must obey the school rules. 你必須遵守校規。
情態動詞數量不多,但用途廣泛,主要有下列: can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) . 情態動詞的位置: 情態動詞在句中放在謂語動詞之前, 謂語動詞前若有助動詞,則在助動詞之前,疑問句中, 情態動詞則在主語之前。 I can see you. Come here. 我能看見你,過來吧。
He must have been away. 他一定走了。 What can I do for you? 你要什么? How dare you treat us like that! 你怎能那樣對待我們! 情態動詞的特點: 情態動詞無人稱和數的變化, 情態動詞后面跟的動詞需用原形,否定式構成是在情態動詞后面加 "not"。
個別情態動詞有現在式和過去式兩種形式, 過去式用來表達更加客氣, 委婉的語氣, 時態性不強, 可用于過去,現在或將來。 He could be here soon. 他很快就來。
We can't carry the heavy box. 我們搬不動那箱子。 I'm sorry I can't help you. 對不起,我幫不上你。
情態動詞的用法: can (could) 表示說話人能,可以,同意,準許,以及 客觀條件許可,could 為 can 的過去式。 Can you pass me the books? 你能給我遞一下書嗎 ? Could you help me, please? 請問,你能幫助我嗎? What can you do? 你能干點什么呢? Can you be sure? 你有把握嗎? can 和could 只能用于現在式和過去式兩種時態,將來時態用 be able to 來表示。
He could help us at all. 他完全可以幫助我們。 With the teacher's help,I shall be able to speak English correctly. 由于老師的幫助,我將能準確地講英語。
may (might) 可以, 表示說話人同意,許可或請求對方許可。 You may take the book home. 你可以把書帶回家去. May I come in? 我可以進來嗎? May I use your dictionary? 我可以用你的詞典嗎? You may put on more clothes. 你可以多穿點衣服. He said he might lend us some money. 他說他可以借給我們一些錢。
may 否定式為 may not, 縮寫形式是 mayn't. 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, 客氣或對可能性的懷疑。 He told me he might be here on time. 他說他能按時間來。
Might I borrow some money now. 我可以借點錢嗎? He might be alive. 他可能還活著。 Must 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 用來指一般現在時和一般將來時, 過去式可用 have to 的過去式代替。 I must finish my work today. 我今天必須完成我的工作。
You mustn't work all the time. 你不能老是工作。 Must I return the book tomorrow? 我必須明天還書嗎? After such a long walk, you must be tired. 走了這么長的路,你一定困了。
He must be the man I am looking for. 他一定是我要找的人。 He had to go because of somebody's calling him that day. 那天他要走是因為有人叫他。
must + have + 過去分詞,表示現在對過去事物的推測。 He must have told my parents about it. 他一定把這件事情告訴我父母親了。
He must have received my letter now. 他現在一定收到我的信了。 It's six o'clock already, we must have been late again. 已經六點鐘了,我們一定又遲到了。
must 和 have to 的區別: must 表示說話人的主觀思想, have to 表示客觀需要。 You must do it now. 你必需現在就干。
(說話人認為必須現在干) I have to go now. 我得走了。(客觀條件必須現在走) need 需要 多用在否定式或疑問句中. Need I attend the meeting tomorrow? 我需要明天參加會議嗎? You need not hand in the paper this week. 這一周你不必交論文。
need 是一個情態動詞, 他的用法完全和其他情態動詞一樣, 但 need 還可當作實義動詞使用, 這時 need 就象其他動詞一樣,有第三人稱,單復數, 后面加帶 to 的動詞等特性。 I need a bike to go to school. 我上學需要一輛自行車。
Do you need a dictionary? 你需要詞典嗎? She needs a necklace. 她需要一條項鏈。 needn't + have + 過去分詞 表示過去做了沒必要做的事情。
You needn't have taken it seriously. 這件事情你不必太認真。 dare 敢 多用在否定或疑問句中。
The little girl dare not speak in public. 小女孩不敢在公眾面前說話。 Dare you catch the little cat? 你敢抓小貓嗎? dare 除用作情態動詞外,更多的是當實義動詞使用, 用法同實義動詞一樣,要考慮人稱,單復數,時態等。
Do you dare to walk in the dark? 你敢黑夜走路嗎? He doesn't dare to tell the teacher what happened that day. 他不敢告訴老師那天發生的事。 ought 應當,應該 后面跟帶有 to 的動詞不定式。
You ought to read these books if you want to 。
8.情態動詞都有哪些
情態動詞,在英文中主要用來表示說話人的看法、態度等。
它很接近中文里的能愿動詞。從用法上來說,它有這樣幾個特點: 1)各個情態動詞自身都有一定的詞義。
2)情態動詞不能在句中獨立擔當謂語。 3)情態動詞在句中不受任何人稱,性,數變化的影響。
4) 情態動詞后接的不定式(除ought外)都不帶to ,即接動詞原形。英文中的情態動詞主要有:can , could ; may , might ; must ; ought ; need ; dare , dared ,另外,shall , will , should , would在一定的場合也可用作情態動詞。
動詞不定式的基本形式是“to+動詞原形”,有時可以不帶to。動詞不定式(或不定式短語)沒有人稱和數的變化,在句子中不能作謂語。
動詞不定式仍保留動詞的特點,即可以有自己的賓語和狀語。動詞不定式同它的賓語或狀語構成不定式短語。
動詞不定式具有名詞、形容詞和副詞的特征,因此在句子中可以作主語、賓語、表語、賓語補足語、定語和狀語。
9.情態動詞與形態動詞
情態動詞 (Model Verbs) 又稱為情態助動詞 (Model Auxil-iaries)。
英語中助動詞主要有兩類:一是基本助動詞,如have, do, be;二是情態助動詞,如may, must, need等。情態動詞與其他動詞連用表示說話人的語氣。
情態動詞可表達建議、要求、可能和意愿等。情態動詞沒有人稱和數的變化。
在大學英語四、六級考試中,情態動詞部分重點測試以下內容: (1)情態動詞+行為動詞完成式 (2)情態動詞+行為動詞進行式 (3)情態動詞+行為動詞完成進行式 (4)某些情態動詞的特殊用法 一、情態動詞+行為動詞完成式 情態動詞+行為動詞完成式即“情態動詞+ have + v-ed分詞”,表示對過去行為或動作進行推測、評論或判斷。 1. must have v-ed must have v-ed 表示推測過去某事“一定”發生了。
其否定形式為:can't / couldn't have v-ed, 表示過去不可能發生某事。例如: 1)Since the ditch is full of water, it must have rained last night. 2)You couldn't have met my grandmother. She died before you were born. 2. could have v-ed could have v-ed 表示推測過去某動作“很可能”發生了。
例如: 1)“The dictionary has disappeared. Who could have taken it?” 2)“Tom could have taken it. He was alone yesterday.” * / might have v-ed may / might have v-ed 表示推測過去某事“也許”發生了.may 比 might 表示的可能性在說話人看來稍大些。例如: I can't find my keys. I may / might have left them at the school yesterday. 4. ought to / should have v-ed 和 ought not to / shouldn't have v-ed ought to / should have v-ed 和 ought not to / shouldn't have v-ed 用于對已發生的情況表示“責備”、“不滿”,分別表示“本應該…”和“本不應該…”。
例如: 1)With all the work finished, I should have gone to the party last night. 2)You ought not to make fun of him. He is not the one you laugh at but learn from. 5. needn't have v-ed needn't have v-ed 表示過去做了某事,但沒有做的必要, 意為“本沒必要…”。例如: You needn't have waken me up; I don't have to go to work today. 注:表示推測過去某動作發生的可能性時,就表示的可能性程度而言,must最大,could其次,may更次之,might最小。
例如: “I wonder how Tom knew about your past.” “He must / could / may / might have heard of it from Mary.” 二、情態動詞+行為動詞進行式 情態動詞+行為動詞進行式(即情態動詞+ be + v-ing形式),表示推測或評論某動作現在是否正在進行。例如: 1)He must be playing basketball in the room. 2)She may be staying at home. 三、情態動詞+行為動詞完成進行式 情態動詞+行為動詞完成進行式(即情態動詞+ have been + v-ing 形式),表示推測或評論過去某動作是否正在進行或一直在進行。
例如: 1)They should have been meeting to discuss the problem. 2)He may / might have been buying stamps in the post office when you saw him. 四、某些情態動詞的特殊用法 1. need 考試中主要測試 need 作情態動詞與作實義動詞的區別,對此,可參見表* 作情態動詞時,后面跟不帶to 的動詞不定式,即 “need to”。通常用在疑問句和否定句中,表示詢問是否有“必要”,其否定形式為needn't,表示“不必”;疑問形式為 Need … do? 極少用于肯定句。
例如: 1)I don't think we need turn the light on at that time. 2)Need you ride a bike to school? 情態動詞need與實義動詞need 在時態、肯定、否定結構上的對比見表1。 2. dare 考試中主要測試dare作情態動詞和作實義動詞的區別。
情態動詞dare 與實義動詞dare 在時態、肯定、否定、疑問結構上的對比見表2。 3. can 和 may 考試中主要測試can,may或could,might表示可能性的區別及對may構成的疑問句的回答。
時態 情態動詞need 實義動詞 need 現 You need (not) do You (don't) need to do 在 時 He need (not) do He needs (doesn't need) to do 過 You needed (didn't need) to do 去 時 He needed (didn't need) to do 將 You need (not) do You will (not) need to do 來 時 He need (not) do He will (not) need to do 句型 時態 動詞 情態動詞dare 實義動詞 dare 肯定句 現在時 dare to 少用 dare/dares to do 過去時 dare to 少用 dared to do 否定句 現在時 daren't/dare not do do/does not dare (to) do 過去時 dared not do did not dare (to) do 疑問句 現在時 Dare he do? Do you/Does he dear (to) do? 過去時 Dared he do? Did he dare (to) do (1)can, could, may, might都可以表示可能性.can, could表示潛在的可能性或理論上或邏輯判斷上存在的可能性;而may, might則表示事實上的可能性。此外,can還具有“有能力”的意思,而may與might則不具此意。
例如: 1)According to the weather forecast, it may rain tomorrow. 2) Any man with a little sense can see that he is wrong. (2)May I / we …?這一類疑問句的肯定回答為Yes, please.或Certainly;否定回答為Please don't.或No, you mustn't. 例如: “May we leave now?” “No, you mustn't. 。
