英语语法问题：Be careful when/while crossing the street.这个句子是不是独立主格结构?为什么?语法书上说不是.这里when crossing the street是不是仅仅是个伴随状语?

不是独立主格.是时间状语.
再问：是伴随状语吧
再答：时间状语。。。伴随状语是表示伴随的啊
再问：这里是否可以补充主语？You should be careful when you crossing the street.主语相同表伴随啊
再答：不能那么钻牛角尖可以补充主语来分析但是不是所有主语相同都表示伴随。。。
再答：伴随是类似于 he went out with books in his arms
再问：是的，您是对的。在过马路时要注意安全
这里着重强调在这个时间段，而不是强调其伴随状态。
再答：嗯。加油
再答：客气了
