仁爱英语七年级下一般现在时与现在进行时)

一般现在时与现在进行时

班级：姓名：

第一部分：基本知识

（一）一般现在时

1．定义：表示经常性的动作。经常与频率副词（时间状语）连用：often经常, usually 通常, always总是，every每个, sometimes有时，at…在几点钟等。只有第三人称单数用动词三单形式，其余动词均用原形。

2.动词变化：

（1）多数在动词后加s play—plays like—likes；

（2）以s，x，sh，ch，o结尾的动词加es go—goes wash--washes ；

（3）以辅音字母加y结尾，把y改i再加es fly—flies

3.基本结构：动词原形（如主语为第三人称单数，动词要改为第三人称单数形式）

4.否定形式：am/is/are+not；此时态的谓语动词若为行为动词，则在其前加don't,如主语为第三人称单数，则用doesn't，同时还原行为动词。

5.一般疑问句：把be动词放于句首；用助动词do提问，如主语为第三人称单数，则用does，同时，还原行为动词

（二）现在进行时

1. 定义：表示（说话瞬间）正在进行或发生的动作,。经常与now, at the moment, look, listen 等词连用。

2. 基本结构：be (am/ is/ are)＋v-ing（动词的现在分词）

I’m watching TV now.

They’re playing football.

3. 现在分词的构成：

（1）一般情况下在动词词尾加ing。

go→going ask →asking look→looking

（2）以不发音的e结尾的动词，去掉e加ing。

have →having t ake→taking make→making write→writing

（3）以一个辅音字母结尾的重读闭音节，双写最后一个字母，再加-ing。

get→getting swim→swimming begin→beginning shop→shopping

4. 现在进行时态的肯定式、否定式、疑问式及简略回答。

（1）肯定式：be＋v-ing She is singing in the next room.

（2）否定式：be＋not＋v-ing The students aren’t cleaning the room.

（3）一般问句：be动词提前。

肯定答语Yes，主语＋be，否定答语No，主语＋be not。

5.特殊疑问问句：疑问词＋be ＋主语＋doing＋其他？(疑问词＋一般疑问句)

What is the old man doing under the tree?

（三）现在进行时与一般现在时的区别：

1.现在进行时表示动作的暂时性，而一般现在时表示动作的习惯性和经常性

I am watching TV now. （暂时性）

I watch TV every day. （经常性）

2.现在进行时可表示短暂性动作，而一般现在时表示长久性动作。

Lucy is living in Beijing.（短时间居住）

Lucy lives in Beijing.（长久性居住）
