Unit 2 单元语法聚焦练习 2023-2024学年七年级上英语（牛津译林版）

Unit 2 Let's play sports! 单元语法聚焦：行为动词的一般现在时 一.知识点梳理 1、一般现在时的基本用法 一般现在时表示现在的状态或经常性、习惯性的动作。另外，表示主语具备某种性格或能力的句子也要用一般现在时。在一般现在时中，往往含有always, often(经常),usually(通常) ,e very day(每天)等标志词。 在一般现在时中，如果句子包含be动词，其一般疑问句是将be动词置于句首，否定句是在be动词的后面加not。be动词有 am,is 和 are三种形式，依据主语的人称和数而定。 当句子的谓语是实义动词时，除主语是第三人称单数时谓语动词用第三人称单数形式外，其余人称和数作主语时，谓语动词都用原形。实义动词的一般疑问句或否定句要使用助动词do/don't或does/doesn't。 2、行为动词的一般现在时 行为动词的一般现在时的构成：主语+行为动词+（其他） 当主语为第三人称单数（he, she, it,某一人或物）时，谓语动词也要用单数形式。 用好一般现在时，时间状态需牢记; 主语人称是三单，动词要把-s/-es添； 基本用法要记清，状态习惯经常性。 行为动词的一般现在时的变化 （1）肯定句：主语+动词+其它，如： He sings very well. My brother does sports every day. He often plays football. （2）否定句：主语+ don’t/doesn’t + 动词原形+其他 He doesn’t sing very well. My brother doesn’t do sports every day. He doesn’t often play football. （3）一般疑问句：Do/Does + 主语+动词原形+其他 Do you often play football? Yes, I do /No, I don’t. Does he often play football?
