1.一般现在时的结构 ①be 动词：主语+be(am, is, are)+其它。 e.g. I am a boy.我是一个男孩。 ②行为动词：主语+行为动词(+其它)。一般现在时主要用动词的原形表示，如果主语是第三人称单数，则
在动词原形后加"-s"或"-es" e.g. He gets up earlyBiblioteka Baiduin the morning.
动词在词尾加 es dress→dresses, fix→fixes, watch→watches, finish→finishes;以“辅音字母加 y”结尾的动词， 把 y 变为 i，再 study→studies, carry→carries, fly→flies ）
(2)一般现在时的用法
?1.表示经常性或习惯性的动作或行为。常与 always, sometimes, often, usually, never 等副词连用。
e.g. I go to school every day except Saturdays and Sundays. My mother often gets up at 6 o’clock. 2.表示现在的状态，能力，性格，个性。e.g. My father teaches maths. Lin Yan dances well. 3.表示普遍真理或客观事实。e.g. The earth moves around the sun.
