单元语法专项解析及练习
一般现在时（simple
present）就是：
时间：指动作发生在“现在”的时间段内。
状态：一般现在时最容易迷惑的一个问题，就是拿不准什么叫“经常发生的动作或存在的状态”。
这个问题要分两层来讲：
1、规律性：“经常发生的动作”，比如每天起床、吃饭、上学，一个星期去几次超市或新华书店等。
经常性：在生活中，有的事情是有规律的，有的是偶尔做几次。这些都算经常发生的事件。
习惯性：这个动作经常发生，是一般的情况而不是具体的某一次。
真理性：有些动作或状态是永恒的，比如长江向东流、地球绕着太阳转。
2、事物存在的状态。
一般现在时结构:
主语+谓语+其他(表动作)；
主语+be+表语（形容词、名词充当表语）。
注意★：句式结构错则全句都错。
当主语是第三人称单数时，动词变相应的第三人称单数形式。
?(1)?be(am,is,are)动词：(作谓语动词时)?肯定句:主语+be动词(am,is,are)+其它。
如：?①I?am?a?student.(主语+be动词+名词)????
?②They?are?hungry.（主语+be动词+形容词）???
?③He?is?out.(主语+be动词+副词)???
?④That?pen?is?mine.(主语+be动词+代词)???
?⑤I?am?fifteen.(主语+be动词+数词)?
?⑥The?bike?is?under?the?tree.(主语+be动词+介词短语)?运用am,is,are写三个句子??
否定句：主语+?be(am,is,are)?+?not?+其它。?
如：He?is?not?a?worker.他不是工人。?运用am,is,are写三个句子??
一般疑问句：Be(am,is,are)?+主语+其它。?
如：-Are?you?a?student??-Yes.?I?am.?/?No,?I'm?not.?运用am,is,are写三个句子?
特殊疑问句：疑问词+一般疑问句。
如：Where?is?my?bike???运用am,is,are写三个句子
特殊疑问句：
疑问词（what,?where,?who,?when,?which,?whose,?how,?how?many,?how?much,?what?shape,?
what?colour,）,找句子中有没有be动词（is,?am或者are）或情态动词或者助动词?
（特殊疑问句:疑问词+be动词（is,?am或者are）或情态动词或者助动词+其他?）?
?
(2)行为动词：主语+行为动词+（其它）
1.主语不是第三人称单数时，??
肯定句为：主语+动词原形+其它??
否定式为：主语+don't+动词原形+其它??
疑问句为：Do+主语+动词原形+其它？??
e.g.???①We?speak?Chinese.??
②Do?you?speak?Chinese???---Yes,?I?do.?/?No,?I?don't.?
③They?don't?speak?Chinese.??写三个句子??
2.当主语是第三人称单数时：?(he,she,it,A/An,单独的人或事物:Lily/book)?
肯定句为:主语+动词（词尾加s或es）+其它。??
否定式为：主语+doesn't+动词原形+其它.??
疑问句式：Does+主语+动词原形+其它？??
①He?speaks?English.?
②He?doesn't?speaks?English.?
③-?Does?she?go?to?work?by?bike??Yes,?she?does.?/?No,?she?doesn't.?写三个句子??
特殊疑问句：疑问词+一般疑问句。如：How?does?your?father?go?to?work??
