Question

    Recently researchers at the University of Zurich are adding a new member to the drone （无人机） family． Unlike most drones whose application is to make selfies （自拍） or transport something， this drone was built with first aid workers and rescue efforts in mind． Disaster sites are rarely of logical shapes and sizes． So having a drone that could change its shape and size to fit through tight spaces on the fly could prove extremely valuable．

As is often the case in experimental robotic projects， researchers met some technical shortcomings at the beginning． The airplane mode of the existing aircraft， such as passenger planes helicopters and the common drones， couldn't meet the demand of different environmental features． Eventually， they turned to animals for inspiration﹣specifically how some birds can fold their wings to fly through narrow passages．

What makes it distinguishing is that when faced with a narrow passage， it can change into an H shape． Or it can shrink itself into an O shape， arms folded into its body． And if that isn't enough it can also transform into a T shape， allowing an on﹣board camera on the central frame to， get as close as possible to its focal object． While the working concept model is impressive， the researchers aren't done with the folding drone yet They want to improve the structure of the drone so that it can fully fold in three dimensions （维度）， offering even mare shapes， And they want to create full auto operation﹣a drone that looks at the changing land features in， for example， an apartment building partly destroyed by an earthquake and changes its shape to meet is current needs． Researchers say their final goal is to give the drowse a high﹣level instruction such as "enter that building， inspect every mom and come back" and let it figure out by itself how to do it．Therefore， it's reasonable to hope the new drone will play an important supporting role in disaster rescue．

1.What was the new done initially designed to do？

A.To provide disaster relief．

B.To take air photography．

C.To convey a heavy load．

D.To send a message signal．

2.Where did the researchers get the inspiration？

D.From common drones．

3.What is the drone's biggest advantage？

A.It has a unique shape．

B.It can change its shape．

C.Its arms are flexible．

D.It can reach its target．

4.Which can be the best title for the passage？

A.A Drone： To Fold and Unfold in the Sky．

B.A Drone： To Transport Goods in the Future．

C.A Drone： To Make Selfies for Fun．

D.A Drone： To Make a Difference in Rescue．

【解析】

本文是一篇科普说明文。文章主要讲述了研究人员们正在设计一种新型无人机用于救灾当中。

1.

细节理解题。根据第一段“Unlike most drones whose application is to make selfies（自拍）or transport something， this drone was built with first aid workers and rescue efforts in mind．最近，苏黎世大学的研究人员正在为无人机家族增加一个新成员．与大多数无人机用于自拍或运输某些东西的无人机不同，这种无人机的建造首先考虑了急救人员和救援人员。”可知，新产品最初设计的目的是提供救灾，故答案为A选项。

2.

细节理解题。根据第二段“Eventually，they turned to animals for inspiration﹣specifically how some birds can fold their wings to fly through narrow passages．最终，他们转向动物寻求灵感，特别是一些鸟如何折起翅膀飞过狭窄的通道。”可知，研究人员从飞行的生物那里得到灵感，故答案为C选项。

3.

细节理解题。根据第三段“What makes it distinguishing is that when faced with a narrow passage，it can change into an H shape，Or it can shrink itself into an O shape， arms folded into its body． 区别在于，面对狭窄的通道时，它可以变成H形，或者它可以收缩成O形，双臂折叠到身体里。”可知，无人机的最大优势是可以改变形状，故答案为B选项。

4.

主旨大意题。第一段 Unlike most drones whose application is to make selfies （自拍） or transport something， this drone was built with first aid workers and rescue efforts in mind．（大多数无人机都是用来自拍或运送东西的，而这款无人机是为急救人员和救援人员设计的。）是全文的主题句，结合全文内容，可知本文主要讲的是一种用于救援工作的无人机，所以这篇文章最好的题目是“无人机:在救援中有所作为”结合选项，答案为D选项。
