一般现在时讲解与练习
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。
构成： 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"-s"或"-es"或变“y”为“ies”如：Mary likes Chinese.玛丽喜欢汉语。Miss Gu teaches us English. 顾老师教我们英语。 She studies Chinese every day.她每天学习语文。否定句、一般疑问句、特殊疑问句：
1. be动词的变化。 否定句：主语+ be + not +其它。 如：He is not a worker.他不是工人。
一般疑问句：Be +主语+其它。 如：-Are you a student? -Yes. I am. / No, I’m not.
特殊疑问句：疑问词+一般疑问句。如：Where is my bike?
2.行为动词的变化。 否定句：主语+ don’t( doesn’t ) +动词原形(+其它)。如：I don’t like bread.
当主语为第三人称单数时，要用doesn’t构成否定句。如： He doesn’t often play.
一般疑问句：Do( Does ) +主语+动词原形+其它。如：- Do you often play football?
- Yes, I do. / No, I don’t.
当主语为第三人称单数时，要用does构成一般疑问句。如：- Does she go to work by bike?
- Yes, she does. / No, she doesn’t.
特殊疑问句：疑问词+一般疑问句。如：How does your father go to work?
一般现在时的动词形式
一般现在时主要由动词原形表示，但第三人称单数后的动词词尾有所变化。第三人称单数动词词尾的变化有几种形式： 一般情况 加-s reads, says, takes 以ch, sh, s, x, 或o结尾的词 加-es teaches, washes, goes, misses, mi xes 以辅音字母加y结尾的词 变y为i再加-es studies, cries, carries
一般现在时：表示站在“现在”这个时段叙述一般情况下发生的事情或状态, 经常性或习惯性的动作。 用法：（1）Be型句子（即句子里动词为am或is或are）以be为助动词，注意主谓搭配
例：He is a teacher. → Is he a teacher? Yes, he is. / No, he isn’t → What is his job?
I am / You are / He is / She is / It is / We are / You are / They are
(2) 行为动词句子（do型）
Ⅰ 主语为第一，第二人称及复数，助动词为do (don’t).
My parents like watching TV in the evening. → Do your parents like watching TV in the evening? Yes, they do. / No, they don’t. → What do they do in the evening?
Ⅱ 若人称为第三人称单数，助动词为does (doesn’t), 肯定句(仅肯定句)时动词要有变化，否定句与疑问句动词不变（基本同名词复数变化）与上面的一组句子比较。
My father likes watching TV. → Does your father like watch TV ? Yes, he does. / No, he doesn’t. → What does your father do in the evening?
一般现在时动词口诀: 肯定句：单数开头S形式 ，复数，你我用原形
否定句：单数开头doesn’t加动词，复数、你我don’t加动词
一般疑问句：单数Does××加动词，复数、你我Do××加动词
2.第三人称单数的动词变化规则
（1） 多数动词直接加s: runs gets likes collets takes plays climbs…….
（2） 结尾是s, x, sh, ch, o,前为辅音字母, 结尾加es : watches teaches goes does washes crosses mixes
（3） 动词末尾y前为辅音: 将y改i加es: study→studies fly→flies y前若为元音则直接加s: buys says
