陳述句變成一般疑問句和否定句.docx

英語中如何把陳述句變成一般疑問句和否定句一、一般疑問句什么是一般疑問句:用Yes 或No 作答的疑問句叫一般疑問句。要將陳述句變成一般疑問句，可以遵循下列步驟：1.句子中有be(am is are was were )動詞、情態(tài)動詞（can would may ）、will 時，只要直接把這些詞置于句首，句末改成問號。 例：It is rainy today. Is it rainy today?Toms father can play the pianoCan Toms father play the piano? 2.如果句中沒有be 動詞、助動詞或情態(tài)動詞，則根據(jù)謂語動詞的形式借助do 的相應(yīng)形式放在句首，必須在句首加上助動詞Do 、Does （單三）、Did （過去式）加上這些助動詞后，句子中謂語動詞必須用原形。英語中如何把肯定句變成否定句例：They go to school by bike. They do not go to school by bike.二肯定句變否定句1.句子中有be(am is are was were ) 動詞、情態(tài)動詞（can would may）、will 時，只要直接在這些詞后加not.例：It is rainy today. It is not rainy today.Toms father can play the piano Toms father can not play the piano .2. 謂語動詞是行為動詞時，必須在動詞前加上動dont 、doesnt（單數(shù)第三人稱）didnt（過去式）, 句子中謂語動詞用原形。例：They go to school by bike. They dont go to school by bike.注意：1.在把肯定句改成否定句或一般疑問句的時候, 要注意句thing 、somebody 等詞，如果有也必須進(jìn)行改變，already 要改成yet ，some 、something 、somebody 等分別改成any 、anything 、anybody 等。例：There is some water on the playground.Is there any water on the playground?2.在改成否定句的時候注意把too 改成either, both改成neither, all改成none 等.3. 在改成一般疑問句的時候，常常把第一人稱I/we改成第二人稱you, my /our改成第二人稱 your, me/ us改成第二人稱you 。例：I usually have lunch at schoolDo you usually have lunch at school? My father is playing soccer. Is your father playing soccer?三. 一般疑問句的回答一般疑問句往往采用簡短回答，共由三部分（三個單詞）組成，對這三部分（三個單詞）的確定可以概括例下：1. 第一個詞：不是Yes 就是No 。（有時根據(jù)語氣的不同，Yes 可由Sure, Certainly, Of course等代替.2.第二個詞：問誰答誰。即答語中的主語須與問句的主語一致（但必須用主格代詞）。例：Does she clean her room every day? Yes, she does. Is Annas father a doctor? No，he isnt.Are you a student ? Yes, I am .No, Im not如果主語是 this that,回答時用 it 代替，如果問句中主語these, those,回答時用 they 代替。3. 第三個詞：用什么問，用什么答。即沿用問句中的引導(dǎo)詞。Can Jim play soccer? Yes, he can.Does Mr Bean speak English? Yes, he does.4用No 開頭作否定回答時, 結(jié)尾要加上 not。因?yàn)榛卮鸨仨毷侨糠?，所以否定回答必須縮寫，而肯定回答不能縮寫。Is Lin Lin in Class 3? Yes, she is. / No, she isnt. 或（No, shes not）一般疑問句和否定句專項(xiàng)練習(xí)把下列句子變成一般疑問句和否定句。1.
