小学英语动词的时态与变化规律知识点哎呀,说起小学英语动词的时态和变化规律,这可真是让当年的我头疼了好一阵子呢!不过后来我发现,只要认真观察和总结,其实也没那么难搞。
先来说说一般现在时吧。
这就像是我们每天的日常生活,平平常常,按部就班。
比如说,“I play football every day”(我每天踢足球。
)在这个句子里,“play”就是一般现在时。
一般现在时里,当主语是第三人称单数(他、她、它)的时候,动词就得变一变啦。
就像“He plays football every day”这里的“play”就变成了“plays”。
这就好比他是个特别的家伙,得有点特殊待遇。
那一般过去时呢,就像是回忆过去的故事。
比如说,“I played football yesterday”(我昨天踢足球了。
)这里的“played”就是“play”的过去式。
很多动词的过去式都是有规律的,比如直接加“ed”,像“walked”“looked”;但也有些调皮的家伙,它们的过去式不规则,得专门去记,像“go”的过去式是“went”,“eat”的过去式是“ate”。
还有现在进行时,这就像是正在发生的精彩瞬间!“I am playing football now”(我正在踢足球。
)你看,“be 动词+动词的现在分词”,这里的“playing”就是“play”的现在分词形式。
一般情况下,动词的现在分词就是在动词后面加“ing”,不过也有一些要注意的地方。
比如以不发音的“e”结尾的动词,要先去掉“e”再加“ing”,像“write”变成“writing”;还有重读闭音节的动词,要双写末尾的辅音字母再加“ing”,比如“run”变成“running”。
记得有一次上英语课,老师在讲台上眉飞色舞地讲着这些动词时态的变化规律,我一开始听得云里雾里的。
老师举了个例子:“The bird flies in the sky”(这只鸟在天空中飞。
