英語怎麼變否定句?
英語中的否定句怎麼改??
簡單地說就是在動詞後面加not,有is、am、are的句子會在這些詞後面加not,I am (not) a boy.沒有is、am、are的句子會在動詞前加don*t或者do not,I (don*t)like basketball.如果有must、may、can這類的詞,在這類詞後面加not,I can (not )walk.一般是根據句子的不同情況進行改動。
英語的否定句怎麼寫
英語否定句最關鍵的是加否定詞not、no、none等。
not: not 一般用於be動詞、助動詞do、have等後面。如are not(aren't),is not(isn't),do not (don't),have not(haven't).
no:一般用於名詞之前,表達“沒有。。。”之意。
否定句可分為
(1)一般否定句
I don't know this.
Nonews is good news.
(2)特指否定
He went to his office, not to see him.
I am sorry for not coming on time.
I don't think/believe/suppose/feel/imagine you are right.
(3)部分否定
All the answers are not right
All is not gold that glitters
(4)全體否定
None of my friends smoke.
I can see nothing/nobody.
(5)延續否定
You didn't see him, neither/nor did I.
You don't know, I don't know either.
(6)半否定句
We seldom/hardly/scarcely/barely hear such fine singing.
I know little English. I saw few people.
(7)雙重否定
You can't make something out of nothing.
What's done cannot be undone.
(8)排除否定
(9)加強否定
I won't do it at all.
I can't see it any more.

英語怎麼改否定句和一般疑問句(要詳細的)
動詞的分類
Be動詞:is,am,are,was,were
助動詞:do,does,did,has,have,had
動詞 情態動詞:can,must,may,should,等
實義動詞:run,eat,play,like,等等.
陳述句改為一般疑問句的改法:
一般疑問句:以be動詞、助動詞、情態動詞為句首,句末有問號(?)的句子.例如:
Is she a doctor.她是一名醫生嗎?
Has she got any grapes?她有些葡萄嗎?(這裡的has是助動詞,got(get的原形)是有的意思.
Can you fly?你會飛嗎?
當句子中的謂語只有實義動詞,沒有be動詞、助動詞、情態動詞的時候,句子變一般疑問句時要加do、does、did(do、dose的過去式)其中之一.如:The fox likes grapes.句子的謂語沒有be動詞、助動詞、情態動詞,只有likes,like是實義動詞,因此,句首要加助動詞;又因為the fox是第三人稱單數,句首的助動詞就用does.句子的就變成Does the fox like grapes?注意原來likes中的s,要刪除.
一般疑問句主語和be動詞、助動詞、情態動詞倒裝.沒有這三類詞時要加助動詞.如:
She is a doctor.She usually goes to school at seven.
Is she a doctor?Does she usually go to school at seven?
記住:實義動詞始終在主語的後面.
注意:述句(句子後面只有句號的句子)給成一般疑問句時,一般情況下,還要把第一人稱I、we、my、our改成you、your,把some變成any.如:
I have got some apples.I am making my aeroplane.
變成:Have you got any apples?Are you making your aeroplane?
We are watching TV.變成:Are you watching TV?
還要注意:如果has、have、had、do、does、did後面是名詞時,has、have就不是助動詞了,他們是實義動詞.改一般疑問時不能提前(一般情況下,所有實義動詞都不能提到主語前面),要根據時態加助動詞do、does、did.
如:She has breakfast everyday.
Does she have breakfast everyday?
否定句的改法首先要認清“否”就是“不”的意思,在英語中就是not或not的省略形式n’t.否定句是在be動詞、助動詞、情態動詞後加not或not的縮略形式n’t.人稱不變化.實義動詞不能直接加否定詞,須加助動詞doesn’t(第三人稱單數)、don’t、didn’t.例如:I am English teacher.改成:I am not (aren’t也可以)English teacher.She has got some apples.改成:She hasn’t(has not也可以)got any apples.注意:一些否定詞hardly(幾乎不)few(很少可數)little(很少不可數)nothing(沒有)none(沒有人或物)等也是否定詞.含有此類否定詞的句子也是否定句.am not的否定縮略形式是aren’t
如:Su yang often plays football.可以改成:Su yang does......
