knowing some table manners ( ) important for us 是用is 还是用are
你好,这里应该用is.因为这句话的主语是knowing some table manners这件事,而不仅仅指manners.而knowing some table manners这件事如果把它换成一个代词,可以用it.这样这句话就变成：it ( ) important for us,很容易就能看出应该填is（it=knowing some table manners).
希望对你有所帮助.

is
因为主语是括号前面的整个部分而不是manners

is
前面部分整个分词短语做主语，用单数~~

该用is
因为句意“知道一些餐桌礼节是很重要的。”
主语就是“知道一些餐桌礼仪”（括号前面的部分）这件事，这件事是单数，当然该用单数咯。
