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."

听力原文： The great advance in rocket theory 40 years ago showed that liquid-fuel rackets were far superior in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. However, during the last decade, large, solid-fuel rockets with solid fuels a bout as powerful as powerful fuels have made their appearance, and it is a favorite layman's question to inquire which one is "better". The question is meaningless; one might as well as ask whether a gasoline or a diesel engine is "better", it all depends on the purpose. A liquid-fuel rocket is complicated, but has the advantage that it can be controlled beautifully. The bunting of the rocket engine can be stopped completely; it can be reignited when desired. A solid-fuel rocket, tin the other hand, is rather simple in construction, though hard to build when a really large size is desired. But once you have a solid-fuel rocket, it is ready for action at a very short notice. A liquid fuel rocket has to be fueled flint and Carl not be held in readiness in very long slier it has been fueled. However, once a solid-fuel rocket has been ignited, it will keep burning. It can't be stopped and reignited whenever desired. Because a solid fuel rocket can be kept ready for a long time, most missiles employ solid fuels, but manned space flight needs the line adjustments that can only be pro vided by liquid-fuel rocket. It may be added that a liquid-fuel rocket is an expensive device; a large solid-fund rocket is, by comparison cheap.

However, during the last decade, large solid-fuel rockets with solid fuels about as powerful as liquid fuels have made their appearance, and it is a favorite layman's question to inquire which one is "better".

A solid-fuel rocket, on the other hand, is rather simple in construction, though hard to build when a really large size is desired. But once you have a solid-fuel rocket, it is ready for action at a very short notice. A liquid-fuel rocket has to be fueled first and can not be held in readiness for very long after it has been fueled. However, once a solid-fuel rocket has been ignited, it will keep burning. It can't be stopped and reignited whenever desired. Because a solid-fuel rocket can be kept ready for a long time, most military missiles employ solid fuels, but manned space flight needs the fine adjustments that can only be provided by liquid-fuel rocket. It may be added that a liquid-fuel rocket is an expensive device; a large solid-fuel rocket is, by comparison, cheap.
