  中国的学生从小学三年级就开始学英语,可是为什么有人还是学不懂英语呢。小编在此献上小学英语基础,希望对你有所帮助。

  动词的四种时态

  一般现在时的构成

  1. be动词:主语+be(am, is, are)+其它。如: I am a boy. 我是一个男孩。

  2. 行为动词:主语+行为动词(+其它)。 如: We study English. 我们学习英语。

  当主语为第三人称单数(he, she, it)时,要在动词后加"-s"或"-es"。如:Mary likes Chinese.玛丽喜欢汉语。

  动词+s的变化规则

  1.一般情况下,直接加-s,如:cook-cooks, milk-milks

  2.以s. x. sh. ch. o结尾,加-es,如:guess-guesses, wash-washes, watch-watches, go-goes

  3.以“辅音字母+y”结尾,变y为i, 再加-es,如:study-studies

  动词过去式详解 动词的过去式的构成规则有:

  A、规则动词

  ① 一般直接在动词的后面加ed:如 worked , learned , cleaned , visited

  ② 以e结尾的动词直接加d:如 lived , danced , used

  ③ 以辅音字母加y结尾的动词要改y为i再加ed(此类动词较少)如 study – studied carry – carried worry – worried (注意play、stay不是辅音字母加y,所以不属于此类)

  ④ 双写最后一个字母(此类动词较少)如 stopped

  B、不规则动词(此类词并无规则,须熟记)小学阶段要记住以下动词的原形和过去式:sing – sang , eat – ate ,

  特殊疑问句:以特殊疑问词(what , where , who , which , when , whose , why , how等)开头引导的句子。此类句子应该问什么就答什么,不能用“yes 、no”来回答。

  3.There be句型

  There be 句型与have, has的区别

  1、There be 句型表示:在某地有某物(或人)

  2、在there be 句型中,主语是单数,be 动词用is ; 主语是复数,be 动词用are ; 如有几件物品,be 动词根据最*近be 动词的那个名词决定。
