跟Kakei老师学英语，每日掌握小学课内重难点，今天我们来谈谈让人懵懵懂懂，分不清楚的时态问题。
在学校课程里，所有的时态都可以从三个方面去认识：含义、结构和标识语。
一般现在时
用法：
①习惯：He goes to school by bus every day.
②规律真理：The earth goes around the sun.
③名言：Practice makes perfect
结构：动词原形或三单形式
（主语是非第三人称单数 动词原形、
主语是第三人称单数 三单形式）
标志语：
①频率副词：always,often,usually,sometimes,seldom,never..
②every day/week/Sunday/year...
③无标志语
一般过去时
含义：表示过去发生的动作
I went to the concert yesterday.
结构：动词过去式
标识语：
①yesterday；the day before yesterday；in 2002
②last week/year/month/Saturday...
③....ago
一般将来时
含义：表示将要发生的动作
I am going to see the doctor.
She will see the movie tomorrow.
结构：
am/is/are going to do/will do
标识语：
①tomorrow;the day after tomorrow;in 2022
②next week/year/month/Saturday...
③in 一段时间
