人教版新目标英语七年级上册 unit 3 Is this your pencil.ppt

be动词构成的一般疑问句 一调：找到句中的be动词（am , is ,are)，把be动调到主语前 This is his book. Is this his book? 二改：句中的主语若含有I (my /we )等第一人称代词时，需将它们改为you (your /you ） This is my pencil . Is this your pencil? 三问号：将句末的句号改为问号 如何将含be动词的肯定句变为否定句 一般将含be动词am, is ,are 的肯定句转化为否定句时，直接在be动词am, is ,are 后加上“not”即可。其他部分不变。 e.g.1. This is a ruler . 变：This is not a ruler . 2. I am a student . 变：I am not a student. 3. Tim and I are good friends. 变：Tim and I are not good friends . 口诀 be 动词真伟大， 生出am is are . 表示否定很简单， not加在be 后边。 若要变为疑问句， be应移到主语前。 还有一点要注意， 句末问号别忘记。 2a listen and check( √ ) the things you hear. 棒球：baseball 英式足球： soccer 篮球：basketball 排球：volleyball 乒乓球：ping pong 网球：tennis 羽毛球：badminton 高尔夫球：golf 足球：football(英：足球；美：橄榄球） Lost:丢失物 My name is +姓名 Please call+姓名+at 电话号码 A:What’s this/ that?
