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 take→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
1
I am watching TV now. (暂时性)
2
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) 第二部分:对应练习
