3.人教版七年级上英语语法焦点就是每个单元后面的那个语法(一)be动词.1、be动词包括am, are, is.2、be动词的用法.am → 主语是单数第一人称(即I).e.g. I am…be are → 单数第二人称及所有复数.e.g. You are… The coats are…is → 单数第三人称及不可数名词. e.g. Your father is… The money is…3、否定句式(即改否定句):在be动词之后+not,句子其它部位不变. e.g. He is not a teacher.4、缩写形式.①主语+be,缩写be第一个字母为 ',再与主语合并. e.g. you are → you're Jack is → Jack's② be+not否定形式的缩写,缩写not中“o”为 ',再与be合并. e.g. is not→isn't are not→aren't③不能缩写的情况:this is, these are, those are, am not及缩略的肯定回答. e.g. Yes, I am. (I'm 误) 5、含be动词句子的疑问句型转换.①一般疑问句:将be动词提前,其它照抄不变,最后+?,读升调.(一般第一人称改为第二人称)e.g. The man in the car is her father. → Is the man in the car her father? I'm a middle school student. → Are you a middle school student?②一般疑问句的肯否定回答.肯定回答: Yes,主语+be. 否定回答: No,主语+be+not.e.g. Is he old? Are you a new student? Is your father at home? Yes, he is. Yes, I am.

No, he is not.(isn't)注意:①主语必须用代词回答;②肯定回答不能缩写;③回答第二人称,用第一人称回答.③特殊疑问句(就划线部分提问).1) 方法:将句子被提问(即被划线)的部分改为相对应的疑问词,然后置于句首,接着再将be动词或情态动词提前 (置于疑问词之后),其它部分照抄不变,最后+?(即疑问词+一般疑问句?) e.g. The man in a red cap is her brother. → Who is the man in a red cap?
