现在进行时(一)
现在进行时表示现在(说话瞬间)或现阶段正在进行或发生的动作,常与now, these days等时间状语连用。
★现在进行时由“助动词am / is / are + 动词-ing形式”构成。动词-ing形式的构成是有规律的:
1. 一般情况下,在动词原形末尾直接加-ing。如:
sing → singing clean → cleaning
2. 以不发音字母e结尾的动词,去掉e,再加-ing。如:
make → making write → writing
3. 以重读闭音节结尾的动词且末尾只有一个辅音字母,双写这个辅音字母,再加-ing。如:
swim → swimming run → running
★ 1. 现在进行时的肯定式为“主语+ am / is / are + 动词-ing形式(+ 其他).”。如:
I am doing the dishes now.
Mike is writing a book these days.
Her parents are watching TV now.
2. 现在进行时的否定式为“主语+ am / is / are + not + 动词-ing形式(+ 其他).”。如:
I’m not doing the dishes now.
Mike is not / isn’t writing a book these days.
Her parents are not / aren’t watching TV now.
3. 现在进行时的疑问式为“Am / Is / Are + 主语+ 动词-ing形式(+其他)?”。简略肯定回答为“Yes, 主语(人称代词) + am / is / are.”;简略否定回答为“No,主语(人称代词) + am / is / are + not.”。如:
—Are you doing the dishes now?
—Yes, I am. / No, I’m not.
