时态一：一般现在时／动词第三人称单数一、定义：1、经常性、习惯性的动作；2、事物或人物的特征或状态；3、客观现实、真理或规律。
Example：1. 表示经常性、习惯性、永久性、频率性的动作，通常与副词often, usually, always, every day (year/ month ), once (twice, three times) a day（week/moth/year）, sometimes，in the morning/afternoon/evening，on Sundays等时间状语连用。
They usually go to school by bike.I take the medicine three times a day.She helps her mother once a week.2.表示事物或人物的特征、状态Mary’s father is a policeman.There are 50 students in my class.3. 表示客观真理，科学原理，自然现象等客观事实或格言、谚语等。
The sun rises in the east and sets in the west every day.The man who has never been to the Great Wall is not a real man.Tomorrow is Tuesday.二、结构：肯定句：主语+ v原/v“三单”(主语+ Be/情态动词/行为动词（原形或三单）+其它)否定句：主语+Be/情态动词/do/dose+not+其它一般疑问句：Be/情态动词/do/dose + 主语+其它特殊疑问句：特殊疑问词+ Be 动词/情态动词/do/dose + 主语+其它（对主语提问除外）对主语提问的特殊疑问句= 特殊疑问词+主语+动词原形/三单（肯定句的结构）+？总结：行为动词表示具体的动作，be动词表示状态，情态动词表示态度。
在做肯定陈述的时候，运用的规则是：有do无be；无do一定要加be。
另外，一定要小心：在做句型转换（否定、疑问）的时候，要分别遵守自己的约定：行为动词要请do/does帮忙；有be就直接用be(be提前变成问句，在后面加上not变成否定句)。
