小学英语必背基础知识归纳 小学英语必背基础知识归纳 小学英语是很简单的，因为对语法的要求很低，这个阶段以听课为主，只要将课堂上的知识掌握好就足够了。下面是店铺为大家整理的小学英语必背基础知识，希望对大家有用! 小学英语知识归纳 句型专项归类 1、 肯定句：是指用肯定的语气来陈述的句子，如： I’m a student. She is a doctor. He works in a hospital. There are four fans in our classroom. He will eat lunch at 12:00. I watched TV yesterday evening. 2、否定句：含有否定词或表示否定意义词的句子，如：I’m not a student. She is not (isn’t) a doctor. He does not (doesn’t) work in a hospital. There are not (aren’t) four fans in our classroom. He will not (won’t) eat lunch at 12:00. I did not (didn’t) watch TV yesterday evening. ☆注意 小结：否定句主要是在肯定句的基础上加上了否定词 ―not‖。有动词be的句子则―not‖加在be后面，可缩写成―isn’t，aren’t‖，但am not 一般都分开写。没有动词be的句子则要先在主要动词的前面加上一个助动词(do，does，did)，然后在它后面加上―not‖，你也可以把它们缩写在一起如―don’t , doesn’t , didn’t )。这三个助动词要根据人称和时态来选择，其中―does‖只用于一般现在时主语是第三人称单数的情况，而―did‖只用于一般过去时，不论主语是什么人称和数，都用―did‖ 。 3、一般疑问句：是指询问事实的句子，此类句子必须用―yes‖，或―no‖来回答。 如：Are you a student? Yes, I am / No, I’m not. Is she a doctor? Yes, she is. / No, she isn’t. Does he work in a hospital? Yes, he does. / No, he doesn’t. 4、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。如： What is this? It’s a computer. What does he do? He’s a doctor. 小学英语知识总结 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 , see – saw , have – had , do – did , go – went , take – took , buy – bought , get – got , read – read ,fly – flew , am/is – was , are – were , say – said , leave – left , swim – swam , tell – told , draw – drew , come – came , lose – lost , find – found , drink – drank , hurt – hurt , feel – felt 小学英语知识要点 现在完成时主要用于： 1 、表示到现在为止这一时期中发生的动作或情况，即多次动作的总和。 e.g. We have learnt four English songs this month. 本文来源：https://www.wddqw.com/doc/663952326f175f0e7cd184254b35eefdc8d31589.html
