问题 Thanks to the invention of e-mail, people don’t need (worry) ______ about spending too much money in communicating with people even in foreign countries.
选项
答案to worry
解析 本题考查动词need的用法。need既可作实义动词，也可以用作情态动词。当它用作实义动词时，后接动词不定式to do的形式，而且有人称、数和时态的变化。否定句及疑问句借助助动词do或does；而作情态动词时，后接动词原形，没有人称、数的变化，否定句直接在need后加not，疑问句直接把need提前。本题中，need用作实义动词，因此后接动词不定式。
