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. The first step you should take before fixing any equipment is to _______.A) discover the equipment's faulty partB) decide on the fixing methodC) know your company's safety rulesD) gather information about the equipment41.

题目解答
答案
解析
本文是一篇关于设备维修前准备工作的说明文，主要内容包括熟悉公司安全规则、收集设备信息、利用感官检查设备等。
40题解析
题目问维修设备前第一步应做什么。根据首句“Before fixing any equipment, be familiar with your company's safety rules for working with electrical equipment”（维修任何设备前，先熟悉公司用电设备安全规则），直接对应选项C“know your company's safety rules”（了解公司安全规则）。A选项“发现故障部件”是后续分析步骤，B选项“决定维修方法”由安全规则决定，D选项“收集设备信息”是第二步，均不符合题意。
41题解析
题目问为了更易分析故障操作，建议了解什么。文中提到“Make sure you know how it should work normally. Having this understanding makes it easier to analyze any faults”（确保了解设备正常工作方式，这种理解能让故障分析更轻松），直接对应选项B“how the equipment should operate”（设备应如何运行）。A选项“谁安装的”、C选项“设备位置”、D选项“购买时间”均未提及，排除。
42题解析
题目问为了解设备常见问题应查看什么。文中明确“If there are equipment history records, you should review them to see if there are any frequent problems”（如有设备历史记录，应查看是否存在常见问题），对应选项A“Its history records”（其历史记录）。B选项“操作手册”和C选项“设备图纸”是信息来源，但不针对“频繁问题”；D选项“公司安全规则”与常见问题无关，排除。
43题解析
题目问检查设备部件温度时为何要小心。文中最后一句“but be careful while doing this as some parts may carry electrical current or be hot enough to cause burns”（需小心，因为部分部件可能带电或足够热导致烧伤），对应选项D“They may carry electrical current”（它们可能带电）。A选项“锋利”、B选项“起火”、C选项“停止运行”均未提及，排除。
