加现在分词
例句：She listened to her favourite rock music while singing along with the words.
She was putting on her jeans while asking me to hand her the sweater.
He banged on the door while opeaning it.
In the bathroom she put on some makeup while loojing in the mirror.
The school master looked angrily at the naughty student while talking with his parents.
improving.
现在分词
这个就具体情况而定，如果前面的句子用的是动词原形，后面和前面是并列关系，当然要用动词原形；如果前面用的是现在分词，后面同样也要用。
没有主语就是ing形式了 是来做状语的
