Question

Though measures have now been taken to prevent further price hikes, many people remain _______ over the rising cost of food.

A．be concerning

B．concerns

C．concern

D．concerned

Answer 1

D

试题分析：考察concern用法。形容词concerned担心的；与系动词remain连用，构成系表结构。Concerns是名词担心；句意：尽管措施已经被采取来预防价格上涨，很多人仍然对于食品价格的上涨很担心。故D正确。
点评：该词是高中阶段的重要的词汇之一，concern可以作为动词；介词concerning关于…；还可以构成固定搭配as far as sb be concerned就…而言。
