一般现在时时态讲解及练习题

一般现在时时态讲解及练习题

一、概念：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。

用法可概括为：

①经常性或习惯性动作，常与表示频度的时间状语连用。如：often, always, sometimes, every …, on Sunday等；I go to school on weekdays.

②现在时刻的状态、能力、性格、个性。

如：I am a teacher. She is tall. My father can swim.

③普遍真理、客观事实等。如：The earth moves around the sun.

④表示格言或警句中。如：An apple a day keeps the doctor away. Knowledge is power.

二、构成：一般现在时的构成主要有两种形式：

①含有be的句型：be(am，is或are)：

A．肯定句中，只出现be，如：

I am a student．我是一名学生。

B．否定句中，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或No

—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。)

试题演练：1). She is a beautiful girl with long black hair. (改为否定句和一般疑问句并作肯定否定回答)

_______________________________________________

_________________

2). They are Chinese students. (同上)

_______________________________________________

_______________________________________________

_______________________________________________

_______________________________________

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．否定句中，借助还原：要在实义动词前面加do(does)＋not，do(does)作助动词，本身无意义，常与not缩写成don't(doesn't)，如：

I don't like vegetables．我不喜欢蔬菜。

C．一般疑问句，借助还原：要在句子开头加助动词Do(does)，句尾用问号，回答用Yes或No，

—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。)试题演练：1). Tom goes to school by bike every day. (改为否定句和一般疑问句并作肯定否定回答)

_______________________________________________ _______________________________________________ _______________________________________________ _______________________________________

2). We like playing basketball on the playground after school every day. (同上)

_______________________________________________ _______________________________________________ _______________________________________________ _______________________________________

三、动词单三：主语是任何一个单数名词、不可数名词或者是第三人称单数，谓语动词要进行必要的变化，称为：主语单三，动词单三

动词单三的变化规律是：

(1) 在动词后加-s，如：read - reads，write - writes，say - says

(2) 以s，x，ch，sh, o结尾的词加-es, 如：teach - teaches，wash - washes，guess – guesses, do-does, go-goes

(3) 以辅音字母+y结尾的词变y为i再加-es：如：try - tries，carry - carries

(4) 特殊变化的词：have-has，be-is, am, are

A. Be (是) - am, is, are

I +am …; she/he/it/名词单数+is ; we/you/they/名词复数+are

如: Lucy is at home now. 露茜现在在家。

B. Have (有) - have, has

I/we/ you/they/名词复数+have ; she/he/it /名词单数+has 如: We have six classes every day. 我们每天上六节课。She has math from Monday to Friday.

四、标志词：

1. 频度副词：often, always, sometimes, usually, every…等

2. once a week, once a day, twice a day等

3. on Sundays, on Mondays 等
