英语的学习中如果能积累一些常用句型、短语，效果定会事半功倍的。例如：动词be(is,am,are)的用法、this，that和it用法等，还有哪些是小学英语常用、常考句型、短语呢?下面是我为您收集整理的小学英语常用句型、短语盘点，供大家参考！
小学英语常用句型、短语盘点
1.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，句末问号莫丢弃。还有一条须注意，句首大写莫忘记。
2.this，that和it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. That is a pencil. 这是一支钢笔。那是一支铅笔。
(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。
(5)This is 不能缩写, 而That is可以缩写。如：
This is a bike. That’s a car. 这是一辆自行车。那是一辆轿车。
(6)打电话时，介绍自己用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”，但英语中打电话时绝不可以说：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：
①-Is this a notebook? 这是笔记本吗?
-Yes, it is. 是的，它是。
②-What’s that? 那是什么?
-It’s a kite. 是只风筝。
