初一一般现在时态精讲讲解

初一英语一般现在时态讲解

一、定义与讲解

（2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es.

watch---watches wish---wishes do---does go---goes 一般现在时表示经常或习惯性的动作或一般性事实。，也可表示现在的状态或主语具备的性格和能力。

通常与副词every day（每天），always（总是）,usually（通常）,often（经常）sometimes（有时）,等时间状语连用。 例：（1）表示事物或人物的特征、状态。

The sky is blue.天空是蓝色的。

Mary’s father is an English teacher. 玛丽的爸爸是一名英语老师。

（2

I get up at six every day.我每天六点起床。 She plays sports every day. 她每天都做运动。

（3The table has four legs.桌子有四条腿。

There are 50 students in my class. 我们班有50个学生。 （4）表示客观真理，科学原理，自然现象，等客观事实或格言谚语等。

The sun rises in the east every day.太阳每天从东方升起。

The earth goes around the sun.地球绕着太阳转。 （5）表示平日的喜好。

I like bananas. We don’t like vegetables.

He likes ice cream. She doesn’t like strawberries. 二．只有主语在第三人称单数时用动词的“三单形式”，

其他人称用动词原形。

★ 动词三单形式的变化规则：

1.（1）多数直接在动词词尾加

play — plays like — likes

ask---asks work---works get---gets call---calls

（3）以“辅音字母加 - y”结尾的动词，要先变y为i再加-es.

try---tries study---studies cry---cries fly---flies

三、一般现在时的句子转换：

（1）变一般疑问句：当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等)提到主语的前面， （口诀：一调二变三问号）;

（2）变否定句：在be动词或情态动词后面直接加not变成否定句. (be后not莫忘记)

例：①陈述句：She is my sister..

疑问句→ Is she your sister? Yes, I am./ No, I’m not. 否定句→ She is not my sister.

②陈述句：I can play soccer.

疑问句→ Can you play soccer? Yes,Ican./ No, I can’t.

否定句→ I can not /can’t play soccer.

★ 注意：对一般疑问句的回答：

一般用什么问就用什么来回答。

但以下例外：Is this a pencil? Yes , it is./ No, it isn’t.

Y’s brothers? Y

（3）当句子中没有be动词，也没有情态动词时，变一般疑问句时，在主语前加助动词do (I, we, you,以及复数), does（第三人称单数she,he,it等）变成问句；

（4）变否定句时，在主语后谓语动词前加助动词don’t,

变成否定句，

例：①陈述句：We get up（起床） at 7:00 every morning. 疑问句→Do you get up at 7:00 every morning? 否定句→We don’t get up at 7:00 every morning. ②陈述句：She has a brother.

疑问句→ Does she have a brother? 否定句→ She doesn’t have a brother.

※ 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。

二、单个人名、地名或称呼作主语；是第三人称单数。如： ①Han Mei likes salsd . 韩梅喜欢萨拉。 ②Beijing is in China. 北京在中国。 ③Uncle Wang often plays volleyball.. 王叔叔经常打排球。 三、单数可数名词或

六、当数字或字母作主语时，看作第三人称单数。如： ①
