思考题:表达某人经常在某一时间段做事的时候,根据主语不同,有什么变化,用什么时态?并:(举例说明)
解题思路: 一般现在时表示反复、经常发生的动作或习惯。当主语是第三人称单数时,谓语动词用第三人称单数形式。当主语不是第三人称单数时,谓语动词用原形。
解题过程:
表示反复、经常发生的动作或习惯用一般现在时。常与always, usually, often, sometimes, every day, every year, every week, once a week(一周一次)等连用。
例如:I go to school by bike every day. 我每天骑自行车上学。
We go to school by bike every day. 我们每天骑自行车上学。
She goes to school by bike every day. 她每天骑自行车上学。
Lily goes to school by bike every day. 丽丽每天骑自行车上学。
构成:
◎主语是I , we, you(你), you(你们), they 及两个或两个以上的人或物作主语:
肯定句:主语+动词原形+其他
I play basketball after school.
They play basketball after school.
Tom and his friends play basketball after school.
否定句:主语+don’t +动词原形+其他
I don’t play basketball after school.
They don’t play basketball after school.
Tom and his friends don’t play basketball after school.
一般疑问句:Do + 主语+动词原形+其他?
肯定回答:Yes, 主语+ do.
否定回答:No, 主语+ don’t.
Do you play basketball after school? Yes, I do. /No, I don’t.
Do they play basketball after school? Yes, they do. /No, they don’t.
Do Tom and his friends play basketball after school? Yes, they do. /No, they don’t.
◎主语是he, she, it 及单个人或物作主语:
肯定句:主语+动词第三人称单数+其他
He plays basketball after school.
Tom plays basketball after school.
否定句:主语+doesn’t +动词原形+其他
He doesn’t play basketball after school.
Tom doesn’t play basketball after school.
一般疑问句:Does + 主语+动词原形+其他?
肯定回答:Yes, 主语+ does.
否定回答:No, 主语+ doesn’t.
Does he play basketball after school? Yes, he does. / No, he doesn’t.
Does Tom play basketball after school? Yes, he does. / No, he doesn’t.
动词原形变第三人称单数的规则与名词单数变复数大致相同。
1、 大多数动词在词尾加“s”。如:
stop-stops; make-makes;read-reads; play-plays
2、以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”。 如:
fly-flies; carry-carries; study-studies ; worry-worries
3、以“s, x, ch, sh”结尾的,在词尾加“es”。如:
teach-teaches ; watch-watches
4、以“o”结尾的动词,加“es”。 如:
go-goes; do-does
5. have 的第三人称单数是has。
