2、ho (谁) where (哪里) whose (谁的) why（为什么）when(什么时候）which（哪一个）how old (多大) how many （多少）how much（多少钱）二：形容词比较级详解当我们需要对事物作出比较时，需要用到比较级。比较级的句子结构通常是：什么 + 动词be (am , is , are ) + 形容词比较级 + than（比）+ 什么 ,如：Im taller and heavier than you. （我比你更高和更重。）An elephant is bigger than a tiger. （一只大象比一只老虎更大。）形容词的比较级是在形容词的基
3、础上变化而来的，它的变化规则是： 一般的直接在词尾加er ，如 tall - taller , strong - stronger , 以e结尾的，直接加r ，如 fine finer , 以辅音字母加y结尾的，先改y为i再加er，如funny - funnier 双写最后的字母再加er，如big bigger, thin thinner ,hot hotter注意 比较的两者应该是互相对应的可比较的东西。典型错误：My hair is longer than you.（我的头发比你更长。）比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。应该改为：My hair is long

6、s 30 cm long.三：动词过去式详解 动词的过去式的构成规则有：、规则动词一般直接在动词的后面加ed：如worked , learned , cleaned , visited以e结尾的动词直接加d：如lived , danced , used以辅音字母加y结尾的动词要改y为i再加ed（此类动词较少）如study studied carry carried worry worried （注意play、stay不是辅音字母加y,所以不属于此类） 双写最后一个字母（此类动词较少）如stopped 、不规则动词（此类词并无规则，须熟记）小学阶段要记住以下动词的原形和过去式：sing sang
7、 , eat ate , see saw , have had , do did , go went , take took , buy bought , get got , read read ,fly flew , am/is was , are were , say said , leave left , swim swam , tell told , draw drew , come came , lose lost , find found , drink drank , hurt hurt , feel felt四：动词现在分词详解 动词的ing形式的构成规则： 一般的直接在后面加
8、上ing , 如doing , going , working , singing , eating 以e 结尾的动词，要先去e再加ing，如having , writing 双写最后一个字母的（此类动词极少）有：running , swimming , sitting , getting五：人称和数人称代词物主代词主格宾格第一人称单数I（我）memy（我的）复数we（我们）usour（我们的）第二人称单数you（你）youyour（你的）复数you（你们）youyour（你们的）第三人称单数he（他）himhis（他的）she（她）herher（她的）it（它）itits（它的）复数they
9、（他们/她们/它们）themtheir（他们的/她们的/它们的）六：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 (d
10、oesnt) 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“no
11、t”，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. / N
12、o, 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 are
13、nt.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 li
