摘要:
该小学英语单元复习课件系统梳理了字母Mm-Pp的发音书写、教室物品词汇及短语、核心句型(介绍物品、There be、祈使句)等内容,通过知识框架将字母本身音与自然发音对比、词汇分类表、句型结构解析串联,帮助学生构建从字母到词汇再到句型的完整知识体系。
其亮点在于采用“游戏化输入-情境化应用-分层化练习”的复习模式,如通过“Magic fingers”“Which is missing”游戏强化词汇记忆,对比“a/an”与“the”的用法培养思维品质,设计选择、补全句子等分层练习提升语言运用能力。这种设计兼顾基础巩固与能力拓展,让学生在互动中夯实知识,教师也能通过多样化练习精准把握学情,提高复习效率。

Tips
知识点一:
There be 句型(单复数)
—There is a desk in the classroom. 教室里有一张书桌。
—There are two chairs near the desk. 书桌旁有两把椅子。
规则:
表示“某地有某物”时:
1.主语是单数物品用“There is a/an...”;★★★
2.主语是复数物品用“There are...”。★★★
知识点一:
例:computer(单数)
→There is a computer.;
fan(复数:fans)
→There are three fans.
注意:“a”用于辅音音素开头的单数物品前(如 a desk)
“an”用于元音音素开头的单数物品前(如 an apple)。
知识点一:
3.否定形式:
句型结构:There+be动词+not+其他。
例句:There is not a desk in the classroom.教室里没有桌子。
There are not any apples in the basket.篮子里没有苹果。
注意:如果肯定句中形容很多物品用many修饰时
否定句中由many变成了any(一般疑问句同理)。
用“There is”或“There are”填空。
1. ___________ a blackboard on the wall.
2. _________ four windows in the classroom.
3. _________ a light above the desk.
4. _________ two fans in the room.
5. _________ a chair next to the door.
There is
There are
There is
There are
There is
知识点二:
肯定式祈使句(表请求/指令)
—Open your books, please. 请打开你们的书。
—Stand up, please. 请站起来。
祈使句的含义:用于礼貌地提出请求或发出指令的句子。
特点:省略主语(默认“you”),以动词原形开头,用于向对方发出动作请求或指令,不表疑问、陈述或感叹。
知识点二:
句型结构:常用两种结构:
1. 动词原形 + 宾语+please.
例:Close the door, please. 请关上门。
2. Please + 动词原形 + 宾语.
例:Please turn on the fan.请打开风扇。
知识点二:
注意:句中的动词需用原形,“please”可放在句末(前加逗号)或句首,表达礼貌语气。
否定形式:若要表达“禁止打开门”,需在动词前加“Do not/Don’t”,
即“Don’t open the door, please”,
此时“please”仍表礼貌,使禁止指令更委婉。
根据汉语提示补全句子。
1. 请关上窗户。__________________, please.
2. 请打开风扇。__________________, please.
3. 请打扫黑板。__________________, please.
4. 请坐下。__________________, please.
5. 请进来。____________, please.
Close the window
Turn on the fan
Clean the blackboard
Sit down

介绍教室物品的句型
— This is the classroom. 这是教室。
—This is a chair. 这是一把椅子。
句型结构:指示代词This+be动词 is+a/the+名词单数。意思是“这是一个.....。”
例句:This is a classroom.这是一间教室。
This is the reading room.这是阅览室。
知识点三:
注意区分:定冠词 “the” 与不定冠词 “a” 的用法
1.两种句型结构均为 “This is + 冠词 + 单数名词”(主系表结构,用于介绍单个事物),核心区别在于冠词不同,导致语义、语境和功能完全不同。
2.对比维度 This is the classroom. This is a classroom.
知识点三:
冠词功能 :定冠词 “the”,表特指 ,不定冠词 “a”,表泛指 ;
语境示例:老师带学生走进教室时说:
“This is the classroom. Let’s go in.”(这就是那间教室,我们进去吧)
孩子指着图片中的建筑问“这是什么”,家长回答:
“This is a classroom.”(这是一间教室)
知识点三:
