Tourism is one of the fastest growing sectors of the global economy and developing countries are attempting to cash in on this expanding industry in an attempt to boost foreign investment and financial reserves.
【正确答案】：发展中国家正试图从旅游业这一快速增长的产业中获利，以促进海外投资、增加金融储备。【解析】原句是主谓宾结构的简单句，主语为developing countries，谓语是are attempting，而to cash in on是宾语，译为“乘机利用，靠……赚钱”，汉译时将其与其宾语补足语this expanding industry调换位置，译作“从这一产业中获利”。in an attempt to...在句中作目的状语，译作“以………”，置于句末。
