现在进行时的讲解与练习
一、概念：1、表示说话时正在进行的动作及行为。
2、表示现阶段正在进行的动作。
它的构成关键在于动词形式的变化。即
(1)I am + v-ing + ....
(2) We / You / They / 复数名词 + are + v-ing + ....
(3) He / She / It / 单数名词 + is + v-ing + ....如：
rm doing my homework now .我正在做家庭作业。(指说话 时正在发生的 动作)
We are working on a farm the days .这些天我们在一家农场 劳动。(指 现阶段正在发生的动作
Look ! He is reading .瞧，他正在看书。
现在进行时是由助动词be的人称代词形式加现在分词构成。
动词变现在分词的方法：
情况 | 歌舞青春歌曲下载力卩法 | 例词 |
一般情情况 | 加-ing | play--playi ng, |
以不发音的字母 e结尾 | 去e力卩-ing | Make--mak ing |
以重读闭音节结 尾,末尾只有一 个辅音字母 | 双写末尾辅 音字母,再加 -ing | put — putt ing swim — swimmi ng stop — stopp ing shop — shopp ing run — running sit — sitti ng get — gett ing jog 奥斯卡经典电影歌曲— joggi ng |
| | |
、结构。现在进行时常有三种句型：
(1)肯疋式：王语+ be + v-ing +其它。如：
He is playi ng football
(2)否定式：主语+ be + not + v-ing +其它。如：
He is not ( isn't ) playing football .
(3)疑问式：主要分一般疑问句和特殊疑问句两种句式。 一般疑问句：Be +主语+ v-ing +其它？如：
—Is he play ing football ?
—Yes , he is . ( No , he isn't .)
特殊疑问句：疑问词+ be +主语+ v-ing +其它？如：

(1)以Look !或Listen !开头的句子，提示我们说话时动作正在进行，应用 现在进行时。如：
Look ! The children are playing games over there .
Listen ! Who's singing in the classroom ？
butt(2)当句子中有now (现在)时，常表示说话时动作正在进行，这时也常用 现在进行时。如：

(3)描述图片中的人物的动作时常用现在进行时，以示生动。如：
