参考解析
解析：前面并没有提到过电脑鼠标，这里是泛指，又由于空格后的单词读音由元音音素开头，故选B项。the 是定冠词，特指已提到的人或物；an 是不定冠词，用在以元音音素开头的可数名词前，表示“一个”;a也是不定冠词，用在不是以元音音素开头的可数名词前，也表示“一个”。
这里表示：我们虽然每天都在用鼠标，却没人会思考鼠标是怎么工作的。make制造，制作；do做，干；get得到，收到；work工作，运作。
由空格前的“it gets dirty”可知，空格处应为clean。clear清楚的，明白的，清晰的；clerk店员，职员，办事员；dean清洁，清理；check检查，核对。
按照人类生长的一般规律，学习用手指指东西理应发生在学习说话之前。before在……之前，先于；after在……以后；until到……为止；u沮ess除非，如果不。
鼠标是一项发明创造，而不是一项发现。find发现，找到，发觉；make制作，制造；discover发现；invent发明，创造。
依照逻辑推理，电脑鼠标的引人应该是为了使电脑完成日常任务。四个介词中只有for能够表示目的。
called在这里是“被称作”之意。这句话的意思是电子发光设备被人们称为LED,A项符合题意。
根据空格前一句提到的either可知，滚轮总共有两边，两者中的另一个应用the other来表示。other与复数名词连用，与others表示相同的意思。
later表示一段时间以后，是英语中的习惯用法。late晚的，迟到的，晚期的；Iater一段时间以后；after在……之后；when当……时候。
这里说的是LED的一种功能，即它能探测光线模式的改变。detect探测，发现；develop发展，开发；relieve解除，缓解；support支持，帮助，支撑。
convert…into…是固定短语，表示“把某事物转化为另一事物”。
此处表示的是“给电脑屏幕上的光标定位”。desk书桌，办公桌；table餐桌，目录；screen屏幕；mouse鼠标。
电脑鼠标应该是大多数人都用过的，故选most。much许多，与不可数名词连用；whole全部的，所有的，完整的；most大多数的，大部分的；few不多，很少。
鼠标变脏后，最终要清理，这里用eVentually来表示。comPletely完全地，彻底地；eventually最后地，最终地；specially特别地，特意地；particularly特别，尤其。根据题意，应选B。
结合上下文语境可知，光学鼠标避免了鼠标变脏的问题。ban禁止；avoid避开，避免，防止；allow允许，承认，准许；adapt使适应，使适合。
