1、DSE五星级专题系列 专题一 时态一般现在时态一、导入某人刻苦学习英语，终有小成。一日上街不慎与一老外相撞， 忙说：I am sorry. 老外应道：I am sorry too. 某人听后又道：I am sorry three. 老外不解，问：What are you sorry for 某人无奈，道：I am sorry five. 二、一般现在时态1概述一般现在时表示习惯性、经常性、反复性的动作或存在的状态。“习惯性、经常性、反复性”是一般现在时的三大特性，它不表示特定时间内发生的事。2构成：时态的结构指的是动词的变化形式。一般现在时间有两种结构，一种是动词原形，用于主语为非第三人称时的
2、情况；另一种为动词的第三人称单数形式，用于主语为第三人称时的情况。 often get up early in the morning. father often gets up early in the morning.3. 谈谈“主语为三单，其后动词s添” 在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。可以简单叙述为“主语为三单，其后动词s添”。何谓第三人称单数用一句话概括就是“非你、非我、非复数”，如he, she, it, my father, my mother, my sister, our English teacher, Tom, Mike, Liu J
3、ia, China, my book, etc. sometimes goes to school by bike. father works in the hospital as a doctor.4 . 动词第三人称单数变化规则动词第三人称变化的规则与可数名词复数变化的规则相同。1) .一般在词尾加-s。如：looks, puts. reads, sees, skis等。2）以-o, -s, -x, -sh, -ch结尾的加-es。如：goes, does, misses, passes, mixes, fixes, pushes, wishes, watches, teaches,等。3
4、）以辅音字母加y结尾的，变y为i，再加-es。注意一定是辅音字母加y才变，若是元音字母加y，则直接加-s。如：flyflies,trytries,fryfries,copycopiesbuybuys,enjoyenjoys,playplays,saysays,paypays5. 一般现在时态的用法： 1）. 现阶段经常性，习惯性的动作或者存在的状态 。 I get up at six every morning. He plays tennis once a week.My mother is a teacher. She teaches English in a school. 2).客观真
5、理 例如：The earth goes around the sun.3)在条件状态从句和时间状语从句中，用一般现在时表示将来。 If you dont go soon, youll be late. 如果你不快去的话，你就要迟到了。 I will wait for you until you come back. 我将一直等到你回来。 6. 常用于一般现在时态的时间状语： often usually sometimes always every day never in the morning 等。例题解析：举一反三，学的更轻松！- May I help you, sir - Yes, I
