八年级时态复习一般现在时例A：I study very hard and Tom studies very hard, too.（我很用功，汤姆也很用功。
）例B：The teacher is not in the classroom and the students are very noisy.（老师不在教室，学生都很吵闹。
）解说如例所示主语为第三人称单数时，一般现在时的动词必须使用第三人称单数形式，其他则除“be”以外都使用动词原形(Root Verb)。
一般现在时的用法如下：解说文法上一般现在时所指的“现在(at the time of speaking)”其实其观念并非是绝对的。
这里所指的现在是在表明说话时存在着的事物，其时间领域含盖着过去，也将延伸及将来。
例如：It is very hot today.（今天天气很热。
---如说话时间是在中午，本句话是在表明说话时“天气很热”，实际上“天气热”的现象在中午之前就已开始存在，同时也将延伸到下午。
）例：Dogs bark at strangers.（狗看到陌生人就会吠。
──这句话是在谈狗的习性，说话时不一定有狗正在吠，而狗的这种习性可以追溯及远古，当然也将延伸到将来。
）因此，一般现在时所指的“现在”可以图示如下：一般现在时常可用时间副词如“today，this + time (this week, this year, …)，now，right now，at present，etc.”来修饰。
△动词第三人称单数的规则变化1. 一般情况：加-s 例：reads，writes，says2. 以s，x，ch，sh和部分以o结尾的词加-es 例：teaches，washes，guesses3. 以辅音字母+y结尾的词变y为i再加-es 例：try—tries，carry—carries.☆☆☆[一般现在时的用法] 简述1) 经常性或习惯性的动作，常与表示频腮度的时间状语连用。
