主题语境 人与社会——科技发展——机器苍蝇
(2021·合肥市高三调研) A team of engineers at Harvard University has been
inspired by Nature to create the first robotic fly.The mechanical fly has bee a
platform for a series of new hightech integrated systems.Designed to do what a fly
does naturally，the tiny machine is the size of a fat housefly.Its mini wings allow
it to stay in the air and perform controlled flight tasks.
“It's extremely important for us to think about this as a whole system and not
just the sum of a bunch of individual ponents，”said Robert Wood，the Harvard
engineering professor who has been working on the robotic fly project for over a
decade.A few years ago，his team got the goahead to start piecing together the
ponents.“The added difficulty with a project like this is that actually none of
those ponents are off the shelf and so we have to develop them all on our own，”
he saiD．
They engineered a series of systems to start and drive the robotic fly.“The
seemingly simple system which just moves the wings has a number of interdependencies
on the individual ponents，each of which individually has to perform well，but then
has to be matched well to everything it's connected to，”said WooD．The flight device
was built into a set of power，putation，sensing and control systems.Wood says the
success of the project proves that the flying robot with these tiny ponents can
be built and manufactureD．
While this first robotic flyer is linked to a small，offboard power source，the goal is eventually to equip it with a builtin power source，so that it might
someday perform datagathering work at rescue sites，in farmers' fields or on the
battlefielD．“Basically，it should be able to take off，land and fly around，”he
saiD．
Wood sa，the power，sensing and putation technologies on board could have much
broader applications.“You can start thinking about using them to answer open
scientific questions，you know，to study biology in ways that would be difficult with the animals，but using these robots instead，”he saiD．“So there are a lot of
technologies and open interesting scientific questions that are really what drives
us on a daytoday basis.”
文章大意：本文主要介绍了哈佛大学的一个工程师团队从自然界的昆虫身上得到灵感，设计开发了第一款机器苍蝇。该机器苍蝇包含一系列新的高科技系统，其大小与胖的家蝇一样，设计目的是使其能自然地做苍蝇能做的事，并执行一些飞行任务。
1．Which of the following statements was the difficulty engineers met while
making the robotic fly?
A．They did not have sufficient funD．
B．No readymade ponents were available.
C．There was no model in their minD．
D．It was hard for them to assemble the ponents.
解析：B 考查细节理解。根据第二段尾句中的“The added difficulty with a project
like this is that actually none of those ponents are off the shelf”可知，额外的困难就是，这些组成部件都没有现成的。故选B项。
2．What can be inferred from Paragraphs 3 and 4?
A．The robotic fly has been put into wide application.
B．The robotic fly consists of a flight device and a control system.
C．Information from many sources can be collected by the robotic fly.
D．The robotic fly can just fly in limited areas at present.
解析：D 考查推理判断。根据第四段中的“While this first robotic flyer is linked
to a small，offboard power source”和“Basically，it should be able to take off，land and fly around”可推知，目前由于电池等的限制，该飞行器只能在有限的区域内飞行。因此D项正确。
3．Which of the following can be learned from the passage?
A．Wood's design can replace animals in some experiments.
B．Animals are not allowed in biological experiments.
C．The robotic flyer is designed to learn about insects.
D．There used to be few ways to study how insects fly.
解析：A 考查细节理解。根据最后一段中的“to study biology in ways that would
be difficult with the animals，but using these robots instead”可知，有些试验很难用动物进行，但是可以用机器苍蝇来替代，故选A项。
