欽州市欽北區(qū)戴氏1對(duì)1高考家教的電話

2023-08-14 03:19:48廣西戴氏教育

最近家長(zhǎng)都在找南寧高中培訓(xùn)費(fèi)用的課外輔導(dǎo)機(jī)構(gòu)的信息,小編在網(wǎng)上整理了欽州市欽北區(qū)戴氏1對(duì)1高考家教的電話的內(nèi)容,僅供參考哦。

can+動(dòng)詞原型,can與be動(dòng)詞差不多的,一般疑問(wèn)句也是一樣的,提前can,改我為你,句號(hào)變問(wèn)號(hào),回答是yes,I can/no,I can';t。就這些吧

情態(tài)動(dòng)詞是一種本身有一定的詞義,但要與動(dòng)詞原形及其被動(dòng)語(yǔ)態(tài)一起使用,給謂語(yǔ)動(dòng)詞增添情態(tài)色彩,表示說(shuō)話人對(duì)有關(guān)行為或事物的態(tài)度和看法,認(rèn)為其可能、應(yīng)該或必要等。情態(tài)動(dòng)詞后面加動(dòng)詞原形。[編輯本段]分類(lèi): 情態(tài)動(dòng)詞有四類(lèi): ①只做情態(tài)動(dòng)詞:must,can(could),may(might),ought to ②可做情態(tài)動(dòng)詞又可做實(shí)義動(dòng)詞:need,dare ③可做情態(tài)動(dòng)詞又可做助動(dòng)詞:shall(should),will(would) ④具有情態(tài)動(dòng)詞特征:have(had,has) to,used to[編輯本段]位置: 情態(tài)動(dòng)詞在句中放在謂語(yǔ)動(dòng)詞之前, 謂語(yǔ)動(dòng)詞前若有助動(dòng)詞,則在助動(dòng)詞之前,疑問(wèn)句中, 情態(tài)動(dòng)詞則在主語(yǔ)之前。I can see you. Come here. 我能看見(jiàn)你,過(guò)來(lái)吧。He must have been away. 他一定走了。What can I do for you? 我能幫你嗎? How dare you treat us like that! 你怎能那樣對(duì)待我們![編輯本段]特點(diǎn): 情態(tài)動(dòng)詞無(wú)人稱(chēng)和數(shù)的變化, 情態(tài)動(dòng)詞后面跟的動(dòng)詞需用原形,否定式構(gòu)成是在情態(tài)動(dòng)詞后面加 "not"。個(gè)別情態(tài)動(dòng)詞有現(xiàn)在式和過(guò)去式兩種形式, 過(guò)去式用來(lái)表達(dá)更加客氣, 委婉的語(yǔ)氣, 時(shí)態(tài)性不強(qiáng), 可用于過(guò)去,現(xiàn)在或?qū)?lái)。情態(tài)動(dòng)詞屬非及物動(dòng)詞,故沒(méi)有被動(dòng)語(yǔ)態(tài)。He could be here soon. 他很快就來(lái)。We can';t carry the heavy box. 我們搬不動(dòng)那箱子。I';m sorry I can';t help you. 對(duì)不起,我?guī)筒簧夏恪;局鷦?dòng)詞與情態(tài)助動(dòng)詞最主要的區(qū)別之一是,基本助動(dòng)詞本身沒(méi)有詞義,而情態(tài)助動(dòng)詞則有自己的詞義,能表示說(shuō)話人對(duì)有關(guān)動(dòng)作或狀態(tài)的看法,或表示主觀設(shè)想: What have you been doing since? (構(gòu)成完成進(jìn)行體,本身無(wú)詞義) I am afraid I must be going. (一定要) You may have read some account of the matter. (或許已經(jīng)) 除此之外,情態(tài)助動(dòng)詞還有如下詞法和句法特征: 1) 除ought和used以外,其他情態(tài)動(dòng)詞后面只能接不帶to的不定式。如果我們把ought to和used to看做是固定詞組的話,那么,所有情態(tài)動(dòng)詞無(wú)一例外地只能接不帶to的不定式: We used to grow beautiful roses. I asked if he would come and repair my television set. 2) 情態(tài)助動(dòng)詞在限定動(dòng)詞詞組總是位居

一: They need not have been punished so severely. 3) 情態(tài)助動(dòng)詞用于

第三人稱(chēng)單數(shù)現(xiàn)在時(shí)的時(shí)候,沒(méi)有詞形變化,即其詞尾無(wú)-s形式: She dare not say what she thinks. 4) 情態(tài)動(dòng)詞沒(méi)有非限定形式,即沒(méi)有不定式和分詞形式,也沒(méi)有相應(yīng)的動(dòng)名詞: Still, she needn';t have run away. 5) 情態(tài)助動(dòng)詞的“時(shí)”的形式并不是時(shí)間區(qū)別的主要標(biāo)志。在不少場(chǎng)合,情態(tài)助動(dòng)詞的現(xiàn)在時(shí)和過(guò)去時(shí)形式都可以表示現(xiàn)在、過(guò)去或?qū)?lái)時(shí)間: Would you mind very much if I ask you to do something? She told him he ought not to have done it. 6) 情態(tài)助動(dòng)詞之間是相互排斥的,即在一個(gè)限定動(dòng)詞詞組中只能出現(xiàn)一個(gè)情態(tài)助動(dòng)詞,但有時(shí)卻可以與have和be基本助動(dòng)詞連用: You should have washed the wound. Well, you shouldn';t be reading a novel.[編輯本段]用法 首先它是動(dòng)詞,而且不同于行為動(dòng)詞,行為動(dòng)詞表示的是可以通過(guò)行為來(lái)表達(dá)的動(dòng)作(如寫(xiě),讀,跑),而情態(tài)動(dòng)詞只是表達(dá)的一種想法(如能,也許,敢)。用法是:情態(tài)動(dòng)詞+行為動(dòng)詞原形 例句:I can read this sentence in English. 我能用英語(yǔ)讀這句話。情態(tài)動(dòng)詞是一種本身有一定的詞義,表示說(shuō)話人的情緒,態(tài)度或語(yǔ)氣的動(dòng)詞,但不能單獨(dú)作謂語(yǔ), 只能和其他動(dòng)詞原形構(gòu)成謂語(yǔ)。We can be there on time tomorrow.我們明天能按時(shí)去那兒。May I have your name? 我能知道你的名字嗎? Shall we begin now?我們現(xiàn)在就開(kāi)始嗎? You must obey the school rules.你必須遵守校規(guī)。情態(tài)動(dòng)詞數(shù)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),have (to) ,had better.[編輯本段]功能 助動(dòng)詞(auxiliary)主要有兩類(lèi):基本助動(dòng)詞(primary auxiliary)和情態(tài)助動(dòng)詞(modal auxiliary)?;局鷦?dòng)詞有三個(gè):do, have和be;情態(tài)助動(dòng)詞基本的有十四個(gè):may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to.had better 上述兩類(lèi)助動(dòng)詞的共同特征是,在協(xié)助主動(dòng)詞構(gòu)成限定動(dòng)詞詞組時(shí),具有作用詞的功能: 1) 構(gòu)成否定式: He didn';t go and neither did she. The meeting might not start until 5 o';clock. 2) 構(gòu)成疑問(wèn)式或附加疑問(wèn)式: Must you leave right now? You have been learning French for 5 years, haven';t you? 3) 構(gòu)成修辭倒裝: Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4) 代替限定動(dòng)詞詞組: A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do.[編輯本段]can和could的用法 1. 表示能力或客觀可能性,還可以表示請(qǐng)求和允許。如: Can you finish this work tonight? Man can not live without air. — Can I go now? — Yes, you can. 注意:①could也可表示請(qǐng)求,語(yǔ)氣委婉,主要用于疑問(wèn)句,不可用于肯定句,答語(yǔ)應(yīng)用can(即could不能用于現(xiàn)在時(shí)態(tài)的簡(jiǎn)略答語(yǔ)中)。如:
