| “一般现在时”部落淘宝进程已过半，现在到“温泉小站”来温习一下吧。
一般现在时定义：表示经常发生的动作或存在的状态。
一般现在时构成形式：
1) 行为动词引导的一般现在时：主语（S） + be + 名词 / 形容词 / 介词
例句：I'm a teacher. They are students. We are young. He's here.
2) 行为动词作谓语，人称为一、二人称或者复数人称时：
主语（S） + 动词原形（V） + 其它
例句：I like my country. 我热爱我的祖国。
3) 行为动词作谓语，人称为第三人称单数（如： he, she, it）时：
主语（S3） + V3 + 其它。
例句：Daming comes from China. 大明来自中国。
4) be动词变否定句，在be 后加not ：
S + be + not + 名词（n.） / 形容词（adj.） / 介词（prep.）
例句：It isn't my book. 这不是我的书。
5） 行为动词变否定句，则须先加助动词do 或does, 再加not：
S + don't + V + （其它）
S3 + doesn't + V + （其它）
例句: We don't know.
David doesn't play basketball.
6) 要明确事情发生的强度、密度，可用频度副词：always, usually, often, sometimes, never。这些词在句子中放在动词前面。
例句：I often go to bed at ten. Sometimes we play table tennis on the playground.
