2023年小升初英语重难点知识:句型专项归类1.肯定句:是指用肯定的语气来陈述的句子,如:l'm a student.She is a doctor.He works in a hospital.There are four fans in our classroom.2,否认句:含有否认词或表示否认意义词的句子,如:l'm not a student.He does not (doesn't) work in a hospital.There are not (aren't) four fans in our classroom.注意小结:否认句主要是在肯定句的基础上加上了否认词"not”.有动词be 的句子那么"not"加在be后面,可缩写成“isntarenl",但am not 一般都分 开写.没有动词be的句子那么要先在主要动词的前面加上一个助动词 (do,does,did),然后在它后面加上“ not",你也可以把它们缩写在一起如 "don't, doesn't, didn't ).这三个助动词要根据人称和时态来选择,其中 “does”只用于一般现在时主语是第三人称单数的情况,而“ did”只用于 一般过去时,不管主语是什么人称和数渚B用"did" .3,一般疑问句:是指询问事实的句子,此类句子必须用"yes,或"no" 来回答.如:Are you a student ?

Yes, I did. / No, I didn't.注意小结:一般疑问句是在肯定句的基础上,把动词be调到首位,其他照写,末尾标点符号变成问号即可.没有动词be的句子那么要在句首加上一个助动词(do,does,did) 再把紧跟在后面的动词变回原形,末尾标点符号变成问号即可.这三个助动词也要根据人称和时态来选择,其中"does"只用于一 般现在时主语是第三人称单数的情况,而"did"只用于一般过去时,不管 主语是什么人称和数渚B用"did".一般疑问句有个重要的原那么就是问 和答要一致,即问句里的第一个单词(助动词)和简略答句里的这个词 是一致的.4,特殊疑问句:以特殊疑问词(what, where , who , which z when , whose , why , how等)开头引导的句子.此类句子应该问什么就答什么, 不能用"yes,no"来回答.如:What is this?Where are you going?Who played football with you yesterday afternoon?When do you usually get up?Why do you like spring best ?How are you?注意小结:其中how又可以和其他一些形容词连用组成特殊疑问词组用来 提问,如:how many(多少(数量),how much(多少(钱),how tall(多高), how long(多长),how big(多大),how heavy(多重)例句:How many pencils do you have ?How many girls can you see ?how many用来提问可数名词的数量,主要有以上三种搭配,How many +名词复数 + do you have你有多少How many +名词复数+ can you see你能看见多少How many +名词复数 + are there 有多少
