第三课时(be动词).doc

PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT 1 语法目标：be（am/is/are）动词的用法及其练习（一） be动词用法歌 be动词真伟大，生出am, is, are。 我(I)用am，你(you)用are，is紧连她(she)他(he)它(it)。 其余单数用is，所有复数都用are。（二）含be动词的肯定句变否定句的方法: 否定句很简单，not加在be后边。（三）含be动词的肯定句变一般疑问句的方法若要变为疑问句，be移到主语前。主语变化很简单：“一二互变三不变”，（主语是I,We变you； you变I .we； my，our变your； he,she.it不变。）句首大写莫迟疑，句末问号别忘记。 肯定回答用Yes, 否定回答要用No。(四) Be动词和人称代词的缩写形式：当主语是第一人称I（我）时，用am, 缩写为I’m；主语是第二人称you（你）或复数时，用are, 缩写为you’re，主语是第三人称it/she/he（它/她/他）或名词及代词的单数时，用is, 缩写为it’s/she’s/he’s。如：I am(I’m) Liu Ying. ②You are(You’re)Lin Tao. ③It is(It’s)3344278.巩固练习提高 一）在下面的短文中填上恰当be动词。I ______ a girl.
