小学英语总复习资料-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:Im a student. She is a doctor. He works in a hospital. There are four fans in our classroom. He will eat lunch at 12:00. I watched TV yesterday evening. 2,否定句:含有否定词或表示否定意义词的句子,如:Im not a student. She is not (isnt) a doctor. He does not (doesnt) work in a hospital. There are not (arent) four fans in our classroom. He will not (wont) eat lunch at 12:00. I did not (didnt) watch TV yesterday evening. 注意 小结:否定句主要是在肯定句的基础上加上了否定词 not.有动词be的句子则not加在be后面,可缩写成isnt,arent,但am not 一般都分开写.没有动词be的句子则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dont , doesnt , didnt ).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,不论主语是什么人称和数,都用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 am / No, Im not. Is she a doctor Yes, she is. / No, she isnt. Does he work in a hospital Yes, he does. / No, he doesnt. Are there four fans in our classroom Yes, there are. / No, there arent. Are you going to buy a comic book tonight Yes, I am. / No, I am not. (Yes, we are. / No, we arent.) Will he eat lunch at 12:00 Yes, I will. / No, I will not(wont). Are they swimming Yes, they are. / No, they arent. Did you watch TV yesterday evening Yes, I did. / No, I didnt. 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的句子则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,不论主语是什么人称和数,都用did .一般疑问句有个重要的原则就是问和答要一致,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 , 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？ Its a computer. What does he do？ Hes a doctor. Where are you going？ Im going to Beijing. Who played football with you yesterday afternoon？ Mike. Which season do you like best？ Summer. When do you usually get up？ I usually get up at 6:30. Whose skirt is this？ Its Amys. Why do you like spring best？ Because I can plant trees. How are you？ Im fine. / Im happy. How did you go to Xinjiang？ I went to Xinjiang by train. 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 I have three pencils. How many girls can you see I can see four girls. How many desks are there in your classroom There are 51. 小结:how many 用来提问可数名词的数量,主要有以上三种句式搭配, 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
