9.They say necessity is the mother of invention.While that might not be the case for every invention,most of coolest inventions are definitely useful.The levitating Lightbulb
The US artist and scientist Simon Morris got the idea of making lightbulb float from hoverboards(悬浮滑板).But the floating is not the most amazing part.It was done simply by putting magnets in the bottom of the bulb and in the wooden base.The rejection force between the opposite ends of the magnets does the job.
What's new here is a technology called induction(电磁感应).It allows the ligtbulb to get power from the base even when they aren't in contact.
Shoes that tie themselves
They're not what you think-shoelaces that tie themselves in the way we tie them.Instead,the new shoes have small motors that control their laces.When you step in them,your feet will hit a sensor in the shoes and the motor will automatically tighten the laces.There are also two buttons on side of the shoes to tighten and loosen them so you can control the laces by yourself.They could actually give athletes an advantage during competitions.They are also useful for people who cannot move their arms or fingers easily.
The no-touch thermometer
Maybe,it's an impossible task for little kids putting a thermometer in their armpits and staying still for minutes.
Now,using infrared(红外线) technology,scientists have invented thermometers that take the body's temperature without contacting the body.Users can simply put the thermometer 2.5 centimeters form a patient's forehead and press the button,and it can get the reading in two seconds.
Not touching the body also means cleaner processes,since patients needn't worry about whether someone else has used the thermometer before.
24.Which of the following about the levitating Lightbulb is true?C
A.It runs only by contacting the base.
B.It gets power by floating from hoverboards.
C.It works by the rejection force from magnets.
D.It operates by using infrared technology.
25.Who do you think possibly use self-tying shoes?B
A.Coaches participating in the sports meeting.
B.The elderly whose fingers cannot move.
C.Athletes who cannot run fast enough.
D.Persons who are injured in feet.
26.When used,the no-touch thermometer isA.
A.quick and clean
B.modern but complex
C.neat but inconvenient
D.portable and fashionable
27.What page of a magazine does the passage come from?B
A.Culture.
B.Life.
C.Medicine.
D.News.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了需要是发明之母,但是其实大多数最酷的发明绝对是有用的.
解答 24.C.细节理解题.根据第一部分But the floating is not the most amazing part.It was done simply by putting magnets in the bottom of the bulb and in the wooden base可知磁悬浮灯泡的工作原理是由磁铁的排斥力;故选C.
25.B.细节理解题.根据第二部分They are also useful for people who cannot move their arms or fingers easily可知手指不能移动的老人可能使用自缚鞋;故选B.
26.A.推理判断题.根据第三部分and it can get the reading in two seconds.Not touching the body also means cleaner processes可知使用时,无接触温度计快速且干净的;故选A.
27.B.推理判断题.根据第一部分But the floating is not the most amazing part.It was done simply by putting magnets in the bottom of the bulb and in the wooden base可知文章最可能来自生活杂志;故选B.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
