About all that can be said for it is that -it sometimes works-that in this particular time and place it offers abetter chance for remedying some ofthe world's outrages than any otheravailable strategy.
请问句首的about是什么词性?是不是有点多余?
about在此为副词,= almost,nearly,修饰all.
《韦氏高阶》about,adv: almost, nearly
That's about all I know at this point.
It's about time to go.
That's about all the time we have.
你的句子中的about 就是这种副词用法,而不是介词。所以并不多余。你用almost 替换all,就可以看出用还是不用about的句义差别。
