小学英语一般现在时核心知识点
一、定义:

• 时间短语:every day(每天)、every week(每周)、on Sundays(每周日)、in the morning(在早上)等
3、 句型结构
第一、第二、第三人称复数
第三人称单数
肯定句
主语 + 动词+ 其他
主语 + 动词(+s/es)+ 其他
否定句
主语 + don’t+ 动词原形 + 其他
主语 + doesn’t+ 动词原形 + 其他
一般疑问句及回答
Do + 主语 + 动词原形 + 其他?
→ Yes, 主语 + do.
→ No, 主语 + don’t.
Does + 主语 + 动词原形 + 其他?
→ Yes, 主语 + does.
→/ No, 主语 + doesn’t.
4、 动词形式(核心考点)
1. 三单包含:he/ / /单数名词/不可数名词
2. 当主语为第三人称单数时,动词需要变为第三人称 形式。
3. 第三人称单数变化规则:
· 动词后加 ;
· 动词以s/x/ch/sh结尾加es,
· 动词以o结尾加es,
· 动词以辅音字母+y;去y变i加es
· 不规则变化:have→has do→does go→goes
【小试牛刀】
例:play→plays
Watch→( )
Study→( )
go→( )
wash→( )
sweep→( )
sing→( )
dance→( )
talk→( )
find→( )
hear→( )
have→( )
5、 常见易错点
1. 三单主语漏加-s/es(错:He play → 对:He plays)
2. 否定句句中三单动词仍加-s/es(错:Does she likes the balls? → 对:Does she like the balls?)
3. 客观真理必须用一般现在时(例:The sun rises in the east. 太阳从东方升起)
