一道高中英语语法填空：she has taken a number of English courses,but___ has proved to be useful.
为什麽不能填few?
答
none
翻译：她已经上了很多的英语课，却没有一节课是有效果的。
"none"是指“三者或三者以上都不”，可用于 可数名词和不可数名词。例如：Is there any milk? -None.(这里有牛奶吗？ -没有)。
新年快乐
答
none
答
it/that
答
no one
答
none
从句子看后半句应该指那些课有用/没用,因为动词用单数的has,连词用转折的but,因此应该填否定的none,即那些课都没有用.
few 后用复数动词have
