幫忙分析一下這個(gè)句子
in short, the image that best represents the current crisis is the stereotypical cartoon scene of a man sitting at the breakfast table with a newspaper held up in front of his face, while a woman glares at the back of it, wanting to talk.該句中的“ a man sitting at the breakfast table with a newspaper held up in front of his face, while a woman glares at the back of it, wanting to talk.” while 后面連接的是一個(gè)完整的句子,怎么前面的句子中沒有謂語(yǔ)成分?
