初中一般现在时用法及练习.docx
一般现在时专题讲解1概念：一般现在时表示经常的、习惯性的动作或存在的状态一般现在时表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。可概括为经常性或习惯性动作；长期存在的特征或状态；普遍真理、客观事实等。 2构成：一般现在时的构成主要有两种形式,一般现在时用行为动词的原形，但第三人称单数作主语时，动词的词尾要加-S。： 1be型：句子的谓语动词只有beam，is或are： a肯定句中，只出现be，如： I am a student我是一名学生。 b否认句中，要在be后面加not，如： She isn't a teacher她不是教师。 c一般疑问句，要将be放在句子开头注意句首字母大写，句尾用问号，答语用Yes，主语+be或No，主语+be+not如： Are you ready？你准备好了吗？ Yes，I am是的，我准备好了。 No，I'm not不，我没准备好。 2实义动词型：句中的谓语动词为实义动词也叫行为动词： a肯定句中，只出现实义动词，如： I get up in the morning我早晨起床。 b否认句中，要在实义动词前面加dodoesnot，dodoes作助动词，本身无意义，常及not缩写成don'tdoesn't，如： I don't like vegetables我不喜欢蔬菜。 c一般疑问句，要在句子开头加助动词Dodoes，句尾用问号，简单答语用Yes，主语+dodoes或No，主语+dodoesnot如： Do you like oranges？你喜欢桔子吗？ Yes，I do是的，我喜欢。 No，I don't不，我不喜欢。 3, 一般现在时的用法 1) 经常性或习惯性的动作，常及表示频率的时间状语连用。 时间状语： every, sometimes, often, usually, always, at, on Sunday I leave home for school at 7 every morning. 2) 客观真理，客观存在，科学事实。 The earth moves around the sun. Shanghai lies in the east of China. 3) 表示格言或警句中。 Pride goes before a fall. 骄者必败。 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。 例：Columbus proved that the earth is round.4) if 条件句或when等时间状语从句主将从现第三人称单数的用法在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下： 一、人称代词he, she, it是第三人称单数。如： He likes watching TV. 他喜欢看电视。 She has lunch at twelve. 她十二点吃午餐。 It looks like a cat. 它看起来像只猫。 二、单个人名、地名或称呼作主语；是第三人称单数。如： Han Mei looks like her mother. 韩梅看起来像她的母亲。Beijing is in China. 北京在中国。Uncle Wang often makes cakes. 王叔叔经常做蛋糕。三、单数可数名词或"this / that / the+单数可数名词"作主语时，是第三人称单数。如：A horse is a useful animal. 马是有用的动物。This book is yours. 这本书是你的。 That car is red. 那辆小汽车是红色的。 The cat is Lucy's. 这只猫是露茜的。四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，是第三人称单数。如：Everyone is here. 大家到齐了。There is something wrong with the watch. 这块手表有毛病。This is a pen. 这是一支钢笔。That is an eraser. 那是一块橡皮擦。五、不可数名词作主语时为第三人称单数。如： The milk is in the glass. 牛奶在玻璃杯里。 The bread is very small. 那面包很小。 六、当数字或字母作主语时，看作第三人称单数。如： "6" is a lucky number. "6"是个吉利数字。 "I" is a letter. "I"是个字母。 六、变化规那么 V+s; -ch,-sh,-s,-x,-o+es; -辅音字母+y-y变i+es稳固练习题：写出以下动词的第三人称单数形式 1. work_ read_ clean_ write_ 2. teach_ wash_ guess_ watch_ pass _ fix _3. go_ do_ 4. study_ fly_ cry_ play_ carry _ 5. have_ 一般现在时疑问、否认句专练一、写出以下动词的第三人称单数形式 work_ do_ fly_ cry_ teach_ carry _ wash_ read_ clean_ pass _ fix _ write_ guess_ watch_ go_ study_ play_ have_ 二、把以下句子改为疑问句、否认句第 - 33 - 页1.
