【正确答案】 C
【答案解析】[解析] 本句意思:近几年经济迅速发展。句中boom:繁荣,迅速发展。fall:下降,如:We are expecting a fall in stock prices.我们预料股市价格将要下跌。mistake:错误,如:Tom didn't make a single spelling mistake in his composition.汤姆在这篇作文里一个字也没拼错。growth:增长,如:Exercise and good food are important to the proper growth of a child.运动和营养好的食物对孩子的正常发育十分重要。flaw:缺陷,如:There's a flaw in your plan.你的计划有个缺陷。只有growth意思上和boom最接近。
