D: while不对，应该是并列关系不是转折

注意：

2、             while表转折让步时才能省略主语和系动词，表示当。。。时不能省略

有这个规则吗？请NN确认一下

怎么和我看到的刚好相反

anyname nn在之前的帖子里说

以下是中国教育资源网上搜到的while用法，供参考：（http://edu.jtjy.com)

连词while大致有以下四种用法:

　　1.引导时间状语从句,意为"当……的时候;和……同时",此时的主从句谓语动作同时发生,从句谓语通常是延续性动词。如:

　　Mary watched TV while she ate her supper.玛丽边吃饭边看电视。

　　While she was listening to the radio, she fell asleep.她听着收音机睡着了。

　　while引导从句时,如主从句的主语一致,且从句谓语又含有be,则从句主语和be可省略。while后可直接跟现在分词、名词、形容词或介词短语。如:

　　We are teachers while (we are) serving as students.我们边当老师边当学生。

　　While (he was) yet a youth, he gained many prizes.他年轻时就曾多次获奖。

　　He caught a cold while(he was) on vacation.他度假时患了感冒。

是不是一时笔误啊

nn来看一下吧

语法专区的while的知识点还是解释不了这个问题的

谁有关于while更多的总结呢？

1楼不对。

这题是因为stimu和while语义重复。

OG里有几次这样的用法：A do sth while doing.可以的而且优选。

马上就考

在语法区活跃也是挑战自己信心的方法啊

让NN们来质疑我的回答，这样才能找到问题以免闭门造车

多谢你的吉言 fighting～
