六年级英语肯定句改否定句

一、肯定句改否定句的方法 ：1、 在be动词后加not。如：is not ， are not ， am not， was not， were not；2、 在can，should， will等后加not。如：cannot， should not， will not；3、 上述都没有的，在动词前加助动词否定形式dont/doesnt/didnt。4、 some 改成any。如： I am a girl. I am not a girl.You are a student. You are not a student.You arent a student.This is Toms bag, This is not Toms bag. This isnt Toms bag.答题方法是；否定词not在be后边。二、肯定句改一般疑问句的方法：1、 把be动词放在句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。2、 把can，shall， will等放到句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。3、 上述都没有的，在句首请助动词Do/Does/Did帮忙，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。注意：句首的第一个字母要大写，句尾标点应为“？”。如：I am in Class 6. Are you in Class 6?You are from America. Are you fromAmerica?It is an orange. Is it an orange?答题方法是：要想提问，be提前，句末“？”别忘了。4、 就一般疑问句回答一般疑问句有两种回答，即：肯定回答和否定回答。其中，肯定回答用yes,否定回答用no。 语句顺序为：Yes + 主语 + am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/ isnt/ arent/wasnt/werent.|cant.|dont/doesnt/didnt|.。如：Are you an English teacher?Yes, I am. /No, I am not.Is that a bird? Yes, it is./ No, it isnt.三、对划线部分提问“就划线部分提问”是小学阶段英语学习的难点，但是一旦掌握了规律，就变得容易多了。 小学英语对划线部分提问之答题口诀 ：一代：用正确的疑问词代替划线部分。二移：把疑问词移至句首三倒：颠倒主谓语，但对主语或其定语提问时除外（some 改成any，I改成you，my改成your），四抄：照抄句子剩余部分。总结关键就是：“特殊疑问词+一般疑问句”(即： 先根据划线部分找到特殊疑问词； 再把没划线的部分变成一般疑问句的语序。)特殊疑问词的确定要根据划线内容而定,在小学阶段常出现的有以下几种：1.划线部分是“事或物”，特殊疑问词用what如: This isa book.-What is this?I often play football on Saturdays .-What do you often do on Saturdays ?2.划线部分是“人”，特殊疑问词用who如:He ismy brother.-Who is he ?、划线部分是“地点”，特殊疑问词用where如:The box ison the desk.-Where is the box ?、划线部分是“时间”，特殊疑问词用what time或when如:Itsseven twenty. -What time is it ?I usually get upat six. - When do you usually get up?、划线部分是“年龄”，特殊疑问词用how old如:I amtwelve. -How old are you?My father isthirty-three. -How old is your father ?、划线部分是“职业”，特殊疑问词用what如:Mike isa worker.-What is Mike ?、划线部分是“颜色”，特殊疑问词用what colour如: My hat isblue. -What colour is your hat？8. 划线部分是“数量”，特殊疑问词用how many或how much如:I can seefive kites.-How many kites can you see ?There is some milk in the glass. -How much milk is there in the glass ?、划线部分是“多少钱”，特殊疑问词用how much如:This pen isnine yuan. -How much is this pen ?、划线部分是“形容词性物主代词或名词性物主代词”，特殊疑问词用whose如:That ismy book. -Whose book is that ?The bag isyours.-Whose is the bag ?以下口诀要牢记：1问“谁”用who；2问“谁的”，用whose；3问“地点哪里”，用where；4问“原因”，用why；5问“身体状况”，用how；6问“方式”，用how；7问“年龄”，用how old；8问“多少”，用how many；9问价钱”用how much；10问“哪一个”，用which ；11问“什么”，用what；12问“职业”，用what；13问“颜色”，用what colour；14问“星期”，用what day；15问什么学科，用what subject；16问“什么时候”，用when;17.问几点用Whats the time?或 What time is it?四、同义句型转换同义句型转换，是把意思相同或相近的句子用不同的词汇、短语及句型表示出来。如：Im Peter. My name is Peter.Tom is tall. Tom isnt short.Im fine. Imall right.我们现在学过的大多数句型，在一般情况下（就是不排除有特殊情况）都可以用简单的公式来记忆。1.肯定句变否定句1) 主语+be动词+.*I am a teacher.I am not a teacher.He is a doctor.
