Before fixing any equipment, be familiar with your company's safety rules for working with electrical equipment. These rules determine the methods you can use.Next, gather information about the equipment and the problem. Make sure you know how it should work normally. Having this understanding makes it easier to analyze any faults. Operation manuals and drawings are valuable sources of information. If there are equipment history records, you should review them to see if there are any frequent problems.In many cases, faults exhibit obvious signs that indicate their cause. Through careful examination and logical reasoning, it is often possible to discover the actual faulty part with very little testing.In addition, it is important to use your other senses when examining equipment. The smell of burnt insulation (绝缘材料), for example, can be a strong indicator (信号) of a problem. Paying attention to the sounds produced by the equipment during operation may also provide valuable clues. Furthermore, checking the temperature of various parts can help discover an issue, but be careful while doing this as some parts may carry electrical current or be hot enough to cause burns.40.

题目解答
答案
解析
本题主要考查对文章内容的理解，解题关键在于仔细阅读文章，从文中提取关键信息来回答各个问题。
第40题
文章开篇明确指出“Before fixing any equipment, be familiar with your company's safety rules for working with electrical equipment”，意思是在修理任何设备之前，要熟悉公司操作电气设备的安全规则。这清晰地表明了修理设备的第一步是了解公司的安全规则。而选项A“发现设备的故障部件”、选项B“决定修理方法”以及选项D“收集设备信息”都不是第一步要做的事情。
第41题
文中提到“Make sure you know how it should work normally. Having this understanding makes it easier to analyze any faults”，即要确保了解设备正常的工作方式，因为有了这种了解，分析故障就会更容易。所以为了更容易分析设备的故障运行情况，应该了解设备的正常运行方式，选项B正确。选项A“谁安装了设备”、选项C“设备的位置”和选项D“设备的购买时间”在文中均未提及与分析故障的关联。
第42题
根据文中“If there are equipment history records, you should review them to see if there are any frequent problems”，可知如果有设备历史记录，应该查看这些记录，以了解是否存在常见问题。所以要了解设备的常见问题，应该查看其历史记录，选项A正确。选项B“操作手册”、选项C“设备图纸”和选项D“公司安全规则”虽然也是获取设备信息的来源，但并非用于了解常见问题的关键。
第43题
文中提到“but be careful while doing this as some parts may carry electrical current or be hot enough to cause burns”，说明在检查设备部件温度时要小心，因为有些部件可能带电或者温度足够高会导致烧伤。所以检查设备部件温度时要小心是因为它们可能带电，选项D正确。选项A“它们可能很锋利”、选项B“它们可能引发火灾”和选项C“它们可能停止运行”在文中均未提及。
第44题
文章围绕修理电气设备展开，详细阐述了修理前要熟悉安全规则、了解设备正常工作方式、查阅历史记录，以及利用感官判断故障等内容。所以文章主要是关于如何修理电气设备的，选项B正确。选项A“操作电气设备”、选项C“使用感官检查设备”和选项D“查看设备历史记录”都只是文章中修理设备过程中的一部分内容，不能概括文章的主要内容。
