一般现在时
一般现在时的用法：
1.表示事物或人物的特征、状态。如：The sky is blue.天空是蓝色的。
2.表示经常性或习惯性的动作。如：I get up at six every day.我每天六点起床。
3.表示客观现实。如：The earth goes around the sun.地球绕着太阳转。
一般现在时的结构:
1. be动词：主语+be(am ,is, are)+其它。如：I am a boy.我是一个男孩。
2.行为动词：主语+行为动词(+其它)。如：We study English.我们学习英语。
当主语为第三人称单数(he, she, it)时，要在动词后加或。如：Mary
likes Chinese.玛丽喜欢汉语。
一般现在时常用的时间词：often, usually, sometimes, every day(week,
year...)等。
A. 第三人称单数形式的构成
一般现在时主语是第三人称单数时，谓语动词后要加s或es，其变化规则与名
词变复数的方法大体相同 ：
1. 一般情况下只在动词后加s，如work-works, write-writes.
2. 以o,s, x, sh, ch结尾的动词，后加es，如guess-guesses, mix-mixes,
finish-finishes, catch-catches.
3. 以辅音字母加y结尾的动词，改y为i加es，如study-studies.
注：不规则变化的有have-has
