PEP 小学英语毕业总复习-句型详解 1 句型详解 1、肯定句：是指用肯定的语气来陈述的句子。如：I m 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？
