知识点一：一般现在时
【知识梳理】
(1)一般现在时的基本结构和变化
①be动词：主语+be(am, is, are)+其它。
. I am a 。
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"
. He gets up early in the morning.
①be动词的变化：
：主语+ be + not +其它。 He is not a 。
B. 一般疑问句：Be +主语+其它。 ---Are you a student ---Yes. I am. / No, I'm not.
C. 特殊疑问句：疑问词+一般疑问句。 Where is my bike
②行为动词的变化：
：主语+ don't( doesn't ) +动词原形(+其它)。 I don't like bread. / He doesn't like bread.
B. 一般疑问句：Do ( Does ) +主语+动词原形+其它。
---Do you often play football --- Yes, I do. / No, I don't.
--- Does she go to work by bike --- Yes, she does. / No, she doesn't.
C. 特殊疑问句：疑问词+一般疑问句。How does your father go to work
（注意回顾动词第三人称单数形式变化规则）
一般情况下在词尾加s help→helps, clean→cleans, play→plays, wear→wears, give→gives; 以s, x, ch, sh结尾的动词在词尾加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
。常与always, sometimes, often, usually, never等副词连用。

Lin Yan dances well.
。. The earth moves around the sun. The sun rises in the east.
【注意】此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。如：Our physics teacher said that light travels much faster than sound. 我们的物理老师说光的传播速度比声音的传播速度快得多，在时间、条件、比较等状语从句中，用现在时表示将来的动作，从句的谓语动词用一般现在时。
