22、费用。没有明显故障，空调反复的停。经常停既损害整体的冷却又增加电费，因为反复的开关增加电损耗。这意味着你已经用光了氟利昂，一般只要重新注入。空调开的时候，断路器跳开。这可能是由于较弱的或者老化的断路器造成的。接地的压缩机，或者冷凝器风扇短路。空调有声音但是风扇不运转，这可能是由于你的风扇电风机坏了或者有缺陷；空调的某根线烧了或者电容器有问题。Section C: TranslationSection C: Translation空调结冰形这可能是空调最恼人的问题了，这是由于你的蒸发器坏了或者你的冷冻剂少了。办公室或者家里的空调漏水。这可能是由于管子堵住了；蒸发器盘管生锈了或者空调内部冻住了。要

23、使空调运转正常，防止因空调问题可能带来的昂贵的维修费用，空调维护是必不可少的。最简单的空调维护就是定期清洗空气过滤器。空气过滤器可以确保灰尘在进入蒸发器和风扇前被过滤掉。很多生产商建议每个月清洗一次过滤器。家用空调的维护还包括拿下面板清洗擦干后再装回去。定期维护空调可以减少空调的维修次数但是空调不坏是不可能的。Section DFast readingSection D: TranslationSection D: Translation微波炉诞生于20世纪40年代末的美国。第二次世界大战期间，微波炉技术广泛应用在雷达设备上，因此这一技术也得到了提高。战后，科学家们用这些知识发明了第一台微波炉

24、。事实上正是由于这一历史原因，微波炉起初被叫作“雷达烤箱”。在那时期，由于微波炉体积庞大，只有餐馆和一些其他商家使用。20年代60年代，日本制造出第一台家用微波炉，但当时只有富裕家庭才能买得起。而如今在许多国家人们都能买得起微波炉了。有了微波炉，加热剩饭菜变得非常简单。随着人们越来越多的了解微波炉的便利，微波炉逐渐得到了推广。接下来让我们了解微波炉如何发展的。微波炉是使用一种叫作微波的电磁波来加热食品的。这种微波类似海洋中的水波。大多数食物中都有水分。水分子经微波照射会以非常快的速度振动，食物中的水分子会通过振动相互碰撞，相互摩擦，使食物变热。Section D: TranslationSec

25、tion D: Translation如果用火加热，食物会从外部开始逐渐变热，要加热至内部需要一段时间。而微波炉通过微波可以很快从食物内部开始加热。微波炉的内部由金属制成。这是因为如果微波第一次没有照到食物上，与内壁碰撞之后也会弹回到食物上。在门上覆盖有隔板，这样微波就不会泄漏到外部。位于微波炉中央的是转盘。是否注意到在用微波炉加热时，转盘总是会不停的旋转？微波通过波导管送入微波炉内部时，不管怎样总会有一些地方容易照到微波，而有些地方很难照到，产生出差异来。这样一来，即使对食物进行加热，也会有地方热，有些地方凉。这样食物就不好吃了。怎样才能将微波均匀地照射到食物上呢？科学家反复研究后发现，通过转动食物要比试图改变微波以使其均匀照射更容易解决这一问题。于是就制作了
