  小学英语语法知识点大全

  在现实学习生活中,大家对知识点应该都不陌生吧?知识点是知识中的最小单位,最具体的内容,有时候也叫“考点”。为了帮助大家掌握重要知识点,下面是小编整理的小学英语语法知识点大全,欢迎阅读与收藏。

  小学英语语法知识点1

  一、现在进行时用法

  主语在句首,am is are 跟在后,

  现在分词跟着走,其他成分不可丢。

  表示动作正进行,句中now时间定。

  一般问句,把be提到句前去。

  否定句式也简单,be后只把not添。

  二、特殊疑问句用法。

  What用途广,要问“什么”它当先。(What's this?)

  How开头来“问安”。(How are you?)

  Who 问“谁”。(Who's that man?)

  “谁的”Whose来承担。(Whose eraser is this?)

  询问“某地”用Where。(Where is her cat?)

  “哪一个”which句首站。(which one?)

  三、动词加-s或-es方法歌诀

  动词三单现在式,一般词尾加-s。

  s,x,ch,sh在词尾,直接加上-es。

  词尾若是字母o,加上-es不用愁。

  “辅音字母+y”来结尾,变y为i是正规。

  -es后边紧跟随,study——studies看明白。

  四、“be going to”的用法口诀

  be going to,表打算,准备、计划将干。

  表可能,有必然,通过现象来推断。

  使用它,要注意,疑问形式be提前。

  否定句,更简单,not放在be后边。

  to之后,动原型,be的形式看人称。

  下列词,要注意,come go 和离去(leave)

  进行时,表将来,牢牢记住莫忘记。

  一、形容词性物主代词。

  1、形容词性物主代词8个:

  My、your、his、her、its、our、your、their

  我的、你的、他的、她的、它的、我们的、你们的、它(他、她)们的

  2、形容词性物主代词的特点:

  ①译成汉语都有“的”eg:my 我的 their 他们的

  ②后面加名词:eg:my backpack his name

  ③前后不用冠词 a an the

  This is a my eraser(错误)

  That is your a pen(错误)

  It's his the pen(错误)

  3、I(物主代词)my you(物主代词)your he(物主代词)her we(物主代词)our

  注:在变物主代词时,把原题所给的词加上的,再译成单词就可以了。

  二、名词性物主代词

  1、名词性物主代词和形容词性物主代词一样有8个:

  Mine、yours、his、hers、its、ours、yours、theirs

  我的、你的、他的、她的、它的、我们的.、你们的、它(他、她)们的

  2、名词性物主代词的特点:

  ①译成汉语都有“的”

  ②后面不加名词

  ③名词性物主代词=形容词性物主代词+名词

  eg:the pen is mine 钢笔是我的 (mine=my pen)

  三、单数的句子变成复数的句子

  把单数的句子变成复数的句子很简单,变法是把能变成复数的词变成复数,但a或an要去掉。

  特殊疑问词、形容词、国家及地点通常不变。

  eg:把下列句子变成复数

  1、I have a car.——We have cars.

  2、He is an American boy.——They are American boys.

  3、It's a car.——They are cars.

  4、This is an eraser.——These are erasers.

  5、That is a backpack.——Those are backpacks.

  6、I'm an English teather.——We are English teachers.

  7、It's a new shirt.——They are new shirts.

  8、He's a boy.——They are boys.

  9、She's a singer.——They are singers.

  10、What's this in English?——What are these in English?

  小学英语语法知识点3

  一、动词be(is,am,are)的用法

  我(I)用am,你(you)用are,is跟着他(he)、她(she)、它(it)。

  单数名词用is,复数名词全用are。变否定,更容易,be后not加上去。变疑问,往前提,句末问好莫丢弃。还有一条需注意,句首大写莫忘记。

  二、this,that 和 it 的用法。

  ① this 和 that 是指示代词,it 是人称代词。

  ②距离说话人近的人或物用 this,距离说话人远的人或物用 that。

  如:This is a flower.这是一朵花(近处)

  That is a tree.那是一棵树(远处)

  ③放在一起的两样东西,先说this,后说that。

  如:This is a pen.这是一只钢笔。

  That is a pencil.那是一只铅笔。

  ④向别人介绍某人时说 this is ......不说 that is ......。

  如:This is Helen. Helen, this is Tom.这是海伦。海伦,这是汤姆。

  ⑤This is 不能缩写,而 That is 可以缩写。

  如:This is a bike.这是一辆自行车。

  That's a car.那是一辆轿车。

  ⑥介绍自己,打电话时用 this,询问对方用 that。

  如:Hello! Is that Miss Green? 喂!是格林小姐吗?

  Yes,this is.Who's that? 是的,我是。你是谁?

  注意:虽然汉语中使用“我”和“你”,但是英语打电话种绝对不可以说:I am......,

  are you......?/Who are you?

  ⑦在回答 this 或 that 作主语的疑问句时,要用 it 代替 this 或 that。

  如:Is this a notebook?这是笔记本吗?

  Yes,it is.是的,它是。

  What's that? 那是什么?

  It's a kite. 是只风筝。
