have和has的用法區分
have 是動(dòng)詞原形i have,we have,you have,they have,to have...
has 是第三人稱(chēng)單數時(shí)用 he has,she has,it has
have用于第一人稱(chēng)(I,we),第二人稱(chēng)(you),及第三人稱(chēng)復數(they);has用于第三人稱(chēng)單數(he,she,it)或單數名詞.
have/has的句型轉換
1.否定句
主語(yǔ)+don't (doesn't)+have +….例：
We don't have any water here.我們這兒沒(méi)有水.
This wall doesn't have a window in it.這面墻上沒(méi)有一個(gè)窗戶(hù).
2.一般疑問(wèn)句：
Do (Does)+主語(yǔ)+have+…?
肯定回答：Yes,主語(yǔ)+do (does).
否定回答：No,主語(yǔ)+don't (doesn't).例：
—Do you have a ruler?你有尺子嗎?
—Yes,I do ./No,I don't.是的,我有./不,我沒(méi)有.
—Does Lucy have a twin sister?露茜有個(gè)孿生姐姐嗎?
—Yes,she does./No,she doesn't.是的,有./不,沒(méi)有.
注意：do,does是助動(dòng)詞,do用于第一、二人稱(chēng)單、復數和第三人稱(chēng)復數;does用于第三人稱(chēng)單數形式.回答一般疑問(wèn)句時(shí),主語(yǔ)用人稱(chēng)代詞表示;否定回答中don't或doesn't 一般不分開(kāi)寫(xiě).
注意：have (has)表示“有”時(shí),一般不用于進(jìn)行時(shí)態(tài).
另外,在現代英語(yǔ)中,當“有”講時(shí),have/has的一般疑問(wèn)句可以把have/has直接提前,當have/has作助詞時(shí)表示完成時(shí)態(tài)時(shí)也可以直接提前.例：
They have a book.Have they a book?
3.“have”與“there be句型”的區別
have意為“有”,指所屬關(guān)系;there be表示“某地有某物”,意指“存在”.例：
There's a book on the desk.桌子上有本書(shū).
Xiao Wang has an English-Chinese dictionary.小王有本英漢字典.
have/has的用法口訣動(dòng)詞
have表示“有”，
位置就在主語(yǔ)后。
“三單”主語(yǔ)用has，
其他人稱(chēng)用have。
一般問(wèn)句句首do/does添。
否定句子也一樣，
don’t /doesn’t主語(yǔ)后面站。
1.A dog has four legs.
2.Our school has a library.
3.We have 37 chairs in our classroom.
4.My sister has a nice toy car.
5.Does that girl have a doll?

使役動(dòng)詞have的用法
一. have sb do sth
此結構意為“讓/請某人做某事”，賓語(yǔ)是賓語(yǔ)補足語(yǔ)所表示動(dòng)作的執行者，但賓語(yǔ)補足語(yǔ)表示的動(dòng)作卻發(fā)生在have動(dòng)作之后，即賓語(yǔ)補足語(yǔ)所表示的動(dòng)作在當時(shí)尚未發(fā)生。例如：
The soldiers had him stand with his back to his father.
士兵們讓這男孩背對他父親站著(zhù)。
The teacher had us hand in our homework on time.
老師讓我們按時(shí)交作業(yè)。
We had Alice attend that meeting with him.
我們讓艾麗斯與他一起參加了那個(gè)會(huì )議。
注意：此結構用于否定句中時(shí)，常含“不能容忍、不允許”之意。例如：
I won”t have you say such things.
我可不允許你說(shuō)這樣的話(huà)。
We”ll never have such things happen again.
我們決不允許類(lèi)似的事情再次發(fā)生。
二. have sb / sth doing sth
在have sb / sth doing sth中，doing sth為現在分詞短語(yǔ)，在句中作賓語(yǔ)補足語(yǔ);sb / sth與doing之間存在著(zhù)邏輯上的主謂關(guān)系。有以下兩種主要用法：
1. 多表示“讓某人/某物處于做某事的狀態(tài)”，此時(shí)have也可由keep來(lái)代替。例如：
His parents had him staying at home all the time.
他父母親讓他一直呆在家里。
The night before the procession, the two cheats had their lights burning all night long.
在舉行游行的前一天夜里，那兩個(gè)騙子讓燈整夜亮著(zhù)。
We have never had women working in this part of our company before.
我們以前從來(lái)沒(méi)有讓女性在公司的這個(gè)部門(mén)工作過(guò)。
2. won”t / can”t have sb / sth doing sth含“不允許或禁止”之意，通常可由not allow / not permit / forbid + sb / sth +to do替換。例如：
I can”t have you catching cold. Run and change your wet clothing.
我不能讓你感冒了。快去把濕衣服換掉。
George, I won”t have you shouting at me that way!
喬治，我不允許你那樣對我大吵大叫。
We can”t have them forcing their views on everyone else.
我們不容許他們把自己的觀(guān)點(diǎn)強加于其他所有的人。
三. have sth done
在此結構中，賓語(yǔ)與賓語(yǔ)補足語(yǔ)之間有著(zhù)邏輯上的被動(dòng)關(guān)系，所以賓語(yǔ)補足語(yǔ)一般由及物動(dòng)詞的過(guò)去分詞充當。這個(gè)結構一般有以下三種不同的意思：
1. 表示“請/讓/叫別人(為自己)做某事”，強調主語(yǔ)的意志。例如：
To keep the enemy out of his empire, Emperor Qin Shihuang had all the walls joined up.
為御敵于國門(mén)之外，秦始皇令人將所有的邊墻連成一體。
Mr Howe wants to have his washing machine repaired.
豪先生想請人為他修理洗衣機。
Mrs Smith had two of her teeth taken out last week.
上個(gè)星期史密斯夫人請人拔掉她的兩顆壞牙。
2. 表示“遭遇某種不幸的事情”，說(shuō)明賓語(yǔ)遭遇的是一種意外的事故，并不著(zhù)重說(shuō)明“是誰(shuí)使他遭遇這種災難”。例如：
I had my wallet stolen on my way home last Monday.
上星期一我在回家的路上，錢(qián)包被(人)偷了。
Houses near airports sometimes have their windows broken by the noise of jet planes passing overhead.
機場(chǎng)附近房屋的窗戶(hù)有時(shí)被上空掠過(guò)的噴氣式飛機的響聲震破。
Workers in some industries have their hearing harmed by the noise of the machines.
在一些產(chǎn)業(yè)中，工人的聽(tīng)力常被機器噪音所損害。
3. 表示“使完成某事”。強調事情的結果，而不強調動(dòng)作的執行者。此事可以是別人完成的，也可以是自己參與完成的。例如：
We must have the work finished before the hurricane comes.
我們必須在颶風(fēng)到來(lái)之前完成這項工作。(“我們”可能參加這項工作，也可能沒(méi)參加。)
She told me she had her house repaired.
她告訴我她的房屋修好了。(“她”可能參加了修理工作，也可能沒(méi)有參加。)
The nurse will have your temperature taken.
護士要量你的體溫。(主語(yǔ)The nurse參與完成。)
I have your medicine prepared now.
我已經(jīng)把你的藥準備好了。(主語(yǔ)I可能參與完成。)
四. have+賓語(yǔ)+形容詞/副詞/介詞短語(yǔ)
此結構表示主語(yǔ)“讓某物或某事處于某種狀態(tài)，或使某人到某處”。用作賓語(yǔ)補足語(yǔ)的形容詞、副詞或介詞短語(yǔ)常含有動(dòng)向意義。因此，賓語(yǔ)(人或物)與賓語(yǔ)補足語(yǔ)之間也存在著(zhù)邏輯上的主謂關(guān)系。例如：
It is too hot, so you must have all the windows open.
天氣太熱，你們得讓所有的窗戶(hù)都開(kāi)著(zhù)。
It”s sunny today. You”d better have your flowers out.
今天天氣晴朗，你最好把你的花搬到外面去。
