we don't need buy anything(改错）

原句的错误在于出现了两个谓语——实义动词need和实义动词buy.去掉其中一个或者改变其中一个的成分即可.
正确表达应该是：
we don't need anything.
或者we need not buy anything.或者 we don't need to buy anything.
此题考查need的两种词性——实义动词和情态动词——的用法区分：
第一句中,need作实义动词,表示需要,整句话意思是：我们不需要任何东西.need作实义动词后面不能再跟动词原型,否则造成一句话有两个以上谓语的错误.但是,跟动词不定式做need的补语是可以的,如第三句,need to do sth表示需要干某事.
第二句中,need作情态动词,与can、must、may等情态动词用法一致,否定时直接在后面加not再跟动词原型buy.
