1、 2022年职称英语考试理工类C级阅读判断练习题(12)阅读下面的短文。每篇短文后面都有七句话，请依据短文的内容推断这些话是正确、错误，还是在短文中没有提到。每个试题计1分,共计7分。Computer MouseThe basic computer mouse is an amazingly clever invention with a relatively simple design that allows us to point at things on the computer and it is very productiveThink of all the things you c
2、an do with a mouse like selecting text for copying and pasting1，drawing，and even scrolling on the page with the newer mice with the wheelMost of us use the computer mouse daily without stopping to think2 how it works until it gets dirty and we have to learn how to clean itWe learn to point at things
3、 before we learn to speak，so the mouse is a very natural pointing device Other computer pointing devices include light pens，graphics tablets and touch screens，but the mouse is still our workhorse3The computer mouse was invented in 1964 by Douglas Englehart of Stanford UniversityAs computer screens b
4、ecame more popular and arrow keys were used to move around a body of text，it became clear that a pointing device that allowed easier motion through the text and even selection of text would be very usefulThe introduction of the mouse，with the Apple Lisa computer in 1983，really started the computer p
5、ublic on the road to relying on the mouse for routine computer tasksHow does the mouse work? We have to start at the bottom，so think upside down for nowIt all starts with the mouse ballAs the mouse ball in the bottom of the mouse rolls over the mouse pad，it presses against and turns two shaftsThe sh
6、afts are conneected to wheelswith several small holes in themThe wheels have a pair of small electronic light-emitting devices called light-emitting diodes (LED) mounted on either side4One LED sends a light beam to the LED on the other sideAs the wheels spin and a hole rotates by，the light beam gets
7、 through to the LED on the other sideBut a moment later the light beam is blocked until the next hole is in placeThe LED detects a changing pattern of light，converts the pattern into an electronic signal，and sends the signal to the computer through wires in a cable that goes out the mouse bodyThis c
8、able is the tail that helps give the mouse its nameThe computer interprets the signal to tell it where to position the cursor on the computer screenSo far we have only discussed the basic computer mouse that most of you probably have or have used5 One problem with this design is that the mouse gets
9、dirty as the ball rolls over the surface and picks up dirtEventually you have to clean your mouseThe newer optical mice avoid this problem by having no moving parts词汇：scroll/skrEul/v(在显示屏上)上下移动文本 pad/pAd/n垫板mouse pad 鼠标垫板 graphics/5rAfiks/n图形，图表tablet/5tAblit/n书写板 graphics tablet 图形书写板workhorse/5w:k

12、目前为止，我们只限于争论根本型的电脑鼠标，你们中间多数人或许拥有一个鼠标，或许你们已用过鼠标。练习：1Most computer users want to know how the computer mouse worksARight BWrong CNot mentioned2 According to the attthor，general computer users need not to know how the computer mouse was inventedARight BWrong C Not mentioned3The computer mouse derives i

14、ed6The most durable comptner mice on sale are the IBM onesARight BWrong CNot mentioned7The optical mouse is superior to the basic one in that the former has no moving partsARight BWrong CNot mentioned答案与题解：1B题句的意思是大多数电脑使用者都想了解鼠标的工作原理。这与短文的介绍不符。短文第一段第三句说，大多数电脑使用者每天用电脑却没有想到要了解一下鼠标的工作原理。题句的信息是错误的，故答案为B
15、。2C 题句表达的意思是，短文认为一般电脑使用者无需了解鼠标是如何创造的。题句表达的内容短文中找不到，故答案为C。3A 题句说鼠标的名称源白鼠标主体拖出的一根看上去像鼠尾巴的电线，这与短文第三段倒数其次、第三句所介绍的信息相符，所以，此题选项A是正确答案。4A短文的第三段说到鼠标的部件有滚动部件如滚球，还有光电装置如二极管等。二极管将光信号转换为电信号，传送到电脑，电脑依据收到的电信号作出相应的反响，因此，二极管是鼠标的主要部件，而滚轮等只是帮助性的机械部件。题句对短文信息的推断是正确的，故答案为A。5B 题句说鼠标脏了，就得换用新的。这一说法与短文包含的信息不符。第一段第三句和末段倒数其次句都提到，鼠标脏了，可以擦洁净再用。题句的信息是错误的，故答案为B。6C题句说，当前市场上出售的最耐用的鼠标是IBM生产的鼠标。这一说法短文中找不到，故答案为C。7A末段说到光学鼠标由于没有一般鼠标使用的滚动部件，所以不会吸附灰尘，用不着擦拭，这是一种新型的鼠标。题句是对短文信息的一种合理的推断，所以选项A是答案。
