A study found wireless signals are able to pass through bags and suitcases to judge the sizes of
dangerous metal objects and identify them." These items could include weapons, chemicals,
laptops and batteries for bombs, "the research team said on Tuesday.
Research suggested that Wi-Fi can now be used to estimate the volume of liquids such as water,
acid, alcohol and other chemicals for explosive material. The study led by researchers at the
Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed
a
wireless device with two to three antennas( 天线)that could be fitted in existing Wi-Fi networks.
The detection system analyzes what happens when wireless signals go through and bounce off
objects or materials. The approach, which the paper states, works by separating the wireless
interference( 扰乱)caused by two factors of objects-the material and shape." Most dangerous
objects such as weapons are usually metal or liquid, which have significant interference,"
researchers said.
When it submarinewas tested on a backpack, the accuracy rate topped 95 percent. "But the accurac
y
dropped to about 90 percent when objects inside bags are wrapped. And the tech could save
lives if used in museums, stadiums, theme parks or schools," the team said, noting its design can
inspect bags or luggage without being an exposure to privacy.
It uses channel state information (CSI) that is readily available in low-cost Wi-Fi devices." This
could have a great impact on protecting the public from dangerous objects," said Yingying Chen,
a co-author of the study," There's a growing need for that now. In large public areas, it's hard to
set up expensive screening equipment like what's in airports. Manpower is always needed to
check bags and we want to develop a method to try to reduce manpower. ”
The peer-reviewed study, which recently won a best paper award at the 2018 IEEE Conference
on Communications and Network Security, is now published online." Future work will continue to
focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes,"
researchers said.
（1）What does paragraph 3 talk about?
A. The function of the technique. B. The way the device works.

（2）What's the advantage of the device?
A. It saves people in danger of natural disasters.
B. It passes through bags without damaging them.
C. It uses antennas to pick up networks' signals.
D. It protects personal information from being disturbed.
（3）Why did the researchers study the device according to Yingying Chen?
A. To save money and labour. B. To make full use of Wi-Fi.
C. To protect passengers' privacy. D. To research dangerous objects.
（4）Which of the following can replace the underlined word “ameliorating" in the last


paragraph?
A. Confirming. B. Improving. C. Discovering. D. Examining.
【答案】 （1）B
（2）D
（3）A
（4）B
【分析】 【剖析】本是一篇说明文，介绍了研究人员发现， WiFi 可用于可用于安检。
（1）考察段落粗心。依据第三段中的 “Thedetection system analyzes what happens when
wireless signals go through and bounce off objects or materia ls. 这”个检测系统剖析信号在物体
和资料上穿透和反射时会发生什么。可知选 B。
（2）考察细节理解。依据第四段中的 “notingits design can inspect bags or luggage without
being an exposure to privacy. 可知，不”用翻开和检查人们的个人物件，防止了入侵隐私，可
知选 D。
（3）考察推理判断，依据第五段中的 “Inlarge public areas, it's hard to set up expensive
screening equipment like what's in airports. Manpower is always needed to check bags and we
want to develop a method to try to reduce manpower. 在大型公共”场所，很难像机场那样设
置昂贵的安检设备。检查行李老是需要人力，我们希望开发一种互补的方法来减少人力，
可推知选 A。
（4）考察词义猜想。依据最后一段中的 “Futurework will continue to focus on ameliorating
the accuracy of identifying objects and imaging shapes and volumes 此后的工作将持续”重视于
