Unit 1 This is me!
单元语法聚焦:be动词的一般现在时
一.知识点梳理
1.概述
be动词是系动词的一种,表示“……是……”的意思。现在式有am,is,are三种。这三种动词的原形是be,所以它们称为be动词。
2.动词be的用法
①如果主语是第一人称1时,动词be用am。
I am a student.我是一名学生。
②如果主语是you,they或者名词复数(两个或两个以上的人或事物)时,动词be用are。
Are you Simon?你是西蒙吗?
③如果主语是单数名词、不可数名词或he、she.it时,动词be用is。
Mr Wu is our English teacher.吴老师是我们的英语老师。
3.动词be的句式结构
①肯定句:主语+am( is, are ) +其他.
Jane is a good girl.简是个好女孩。
②否定句:主语+am( is,are)+not+其他.
I am not good at English.我不擅长英语。
③一般疑问句:Am (ls,Are) +主语+其他? 肯定回答:Yes,主语+be. 否定回答:No,主语+be +not.
—ls Tom your classmate?汤姆是你的同吗?
—Yes,he is./No,he isn't.是的,他是。/不,他不是。
[记忆口诀]
巧记含be动词的一般疑问句
我用am,你用are,is连着他、她、它;
单数名词用is,复数名词全用are。
变疑问,往前提,句末问号莫丢弃。
变否定,更容易,be后not莫忘记。
疑问否定任你变,句首大写莫迟疑。
(4)注意:
在肯定的简略回答中,主语应由人称代词的主格充当。如:
—Is Sandy your cousin? —Yes,she is.(画线部分不能用Sandy)
(5)一般疑问句的语调
一般疑问句用升调朗读,简略答语用降调朗读。如:
—Are you a student? (个)你是一名学生吗? —Yes,I am. (1)是的,我是。
