Although there are (few) new words in the passage ,it's difficult for me to read it .

问题描述:

Although there are (few) new words in the passage ,it's difficult for me to read it .
为什么括号里不填“a few”?

few表示极少的,几乎没有,属于否定词,句意:虽然段落里面几乎没有新词,但对我而言阅读它还是很困难.
a few表示一些,属于肯定词,如果用a few的话,句意应该为:虽然段落里面有一些新词,但对我而言阅读它还是很困难.(有没有感觉怪怪的呢?因为它是错的.)
