听力原文： As a tradition, workers in companies are always required to wear suits and fie, but according to a senior government official, Thailand is to ask workers to stop wearing suits as part of the country ' s latest measure to conserve energy. This is the idea of the new government, because Thailand is a tropical country and air-conditioners have been used very commonly, which consume a large amount of energy, but if the workers turned up in shirt sleeves, they wouldn't need air-conditioners turned up so high. At its weekly meeting, the cabinet passed a resolution asking all public servants not to wear jackets and urging private employees to do the same. This has already been practised by the government. At a re cent meeting, only four of six air-conditioners in the cabinet room had been turned on. One of the government officials says, 'Initially it was not hot in the room, but if a meeting lasts a long time, the temperature might need to be lowered a bit.' (31)
