一般现在时(Simple Present Tense)一般现在时也译为单纯现在时。

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”以外都使用原形动词(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。）

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：

一般现在时常可作用如“today，this + time (this week, this year, …)，now，right now，at present，etc.”时间副词来修饰。
