改错题73.The UK is desperately short of scientists and engineers, which means science festivals now have a more important role than ever in conveying to young people how science and engineering can be a funny and rewarding career.
【正确答案】
C
【答案解析】这句话的意思是：英国当下非常缺少科学家和工程师，这意味着科学节比以往任何时候都需要担当起向年轻人进行宣传的重要角色，要让他们知道科学与工程是既有趣又有益的事业。根据句意，科学与工程是fun and rewarding，而不是funny(滑稽的、可笑的)、rewardless(无报酬的、徒劳的)、rewarded(reward的过去式)，排除A、B项。career为可数名词，需要用不定冠词a修饰，排除D项。答案为C。
