请举例说说be动词的用法区别
1、be动词的用法.
be am / is are 现在时
was were 过去时
单数 复数
英语中,be动词选用单数还是复数,要由主语来定,主语是单数,就用单数,反之用复数.
◆ 句中含有be动词时:
肯定句:主语+be + 其他
否定句:主语+ be + not + 其他
一般疑问句:Be +主语+其他
特殊疑问句:疑问词(what / who / when / where) + be +主语 + 其他
I am a teacher.You are right.
She is 16 years old.My father is at home.
The students are playing games.My teacher was ill yesterday.
There is a picture on the wall.
There are two books on the table.
★ be动词用法歌:
我用am,你用are,is 连接他她它.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.
★ be动词作谓语,它后面一般跟名词、形容词或介词短语.
2、助动词的用法.
英语句子按正常语序是“什么人或事物” + “做什么”,即,我们常说的“主语 + 谓语 + 其他”.

肯定句:I / We / They / The students + 动词原形 + 其他 + .
We watch TV every night.
变否定:主语+ don’t + 动词原形 + 其他 + .
We don’t watch TV every night.
一般疑问句 Do + 主语 + 动词原形 + 其他 +
Do you watch TV every night?
Yes,we do./ No,we don’t.
特殊疑问句:疑问词 + do + 主语 + 动词原形 + 其他 +
How often do you watch TV?
② 主语为单数名词或代词时:
肯定句:主语 + 动词第三人称单数形式 + 其他 + .
He watches TV every night.
否定句:主语+ doesn’t+动词原形+其他+.
He doesn’t watch TV every night.
一般疑问句:Does + 主语 + 动词原形 + 其他 +
Does he watch TV every night?
Yes,he does./ No,he doesn’t.
特殊疑问句:疑问词 + does + 主语 + 动词原形 + 其他 +
How often does he watch TV?
③ 过去时的句式(当句子时态为过去时时,动词用过去式,不受主语单复数的影响)
肯定句:主语 + 过去式 + 其他 + .
He / We got up early every morning last year.
否定句:主语 + didn’t + 动词原形 + 其他 + .
He / We didn’t get up early every morning last year.
一般疑问句:Did + 主语 + 动词原形 + 其他 +
Did he / you get up early every morning last year?
Yes,he / we did./ No,he / we didn’t.
