    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(干扰)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 was tested on a backpack, the accuracy rate topped 95 percent. "But the accuracy 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. C、The principle the study is based on. D、The benefit of the study findings.
(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.
举一反三
请阅读下列短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项。

El Nifio, a Spanish term for “the Christ child", was named by South American fishermen who noticed that the global weather pattern, which happens every two to seven years, reduced the amount of fishes caught around Christmas. El Nifio sees warm water, collected over several years in the western Pacific, flow back eastwards when winds that normally blow westwards weaken, or sometimes the other way round.

        The weather effects, both good and bad, are felt in many places. Rich countries gain more from powerful Nifio, on balance, than they lose. A study found that a strong Nifio in 1997 helped American's economy grow by $15 billion, partly because of better agricultural harvest, farmers in the Midwest gained from extra rain. The total rise in agricultural incomes in rich countries is greater than the fall in poor ones.

          But in Indonesia extremely dry forests are in flames. A multi-year drought (干旱)in south-east Brazil is becoming worse. Though heavy rains brought about by El Nino may relieve the drought in California, they are likely to cause surface flooding and other disasters.

The most recent powerful Nino, in 1997-98, killed around 21,000 people and caused damage worth $36 billion around the globe. But such Ninos come with months of warning, and so much is known about how they happen that governments can prepare. According to the Overseas Development Institute(ODI), however, just 12% of disaster-relief funding in the past two decades has gone on reducing risks in advance, rather than recovery and rebuilding afterwards.This is despite evidence that a dollar spent on risk-reduction saves at least two on reconstruction.

Simple improvements to infrastructure (基础设施)can reduce the spread of disease. Better sewers (下水道)make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach. Stronger bridges mean villages are less likely to be left without food and medicine after floods. According to a paper in 2011 by Mr. Hsiang and co-authors, civil conflict is related to El Nino's harmful effects—and the poorer the country, the stronger the link. Though the relationship may not be causal, helping divided communities to prepare for disasters would at least reduce the risk that those disasters are followed by killing and wounding people. Since the poorest are least likely to make up for their losses from disasters linked to El Nino, reducing their losses needs to be the priority.

    The iPhone, the iPad: each of Apple's products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i” --and many other brands are following suit. The BBC's iPlayer--which allows Web users to watch TV programs on the Internet--used the title in 2008. A lovely bear--popular in the US and UK--that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was started last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce(电子商务) first came into use.

    Most “I” products are targeted at(针对) young people and considering the major readers of Independent's “I”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition(定义),” he says.

    “However, thanks to Apple, the term is now connected with portability (轻便).” adds Thorne.

    Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with “Google” and “blog”, readers of BBC Magazines voted “I” as one of the top 20 words that have come to define the last decade(十年).

    But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.

    If you are in charge of a project, the key to success is getting everyone to want to help you. As a director, I point, I suggest, I gently push the actors in the direction I want them to go. In the 1986 movie, "Nothing in Common", Jackie Gleason's character, Max Basner, gets fired from his job as a clothing salesman. The scene, shot on a boat, shows Max's despair about being out of work. I was looking for some gesture that would allow Max to show his feelings.

    Jackie had far more experience at everything than I did, and at first I was frightened. What could I possibly tell "The Great One" about acting? Out of fear I decided to direct by suggestion, and I sat down with Gleason to talk about the scene. "So Max is sad, right?" I said.

    Gleason nodded.

    "And he's probably still carrying his pens with his name on them—the ones he used to hand out to his customers, right?"

    Gleason nodded.

    "So what would you want to do with the pens after you were fired?"

    He was silent for a moment. "Why don't I throw them overboard?"

    I stood up and turned towards the crew. "Hey, everybody, Jackie has a wonderful idea. Let's shoot it."

    After filming the scene, Gleason called me over and said with a smile. "Garry, what kind of wonderful idea am I going to have tomorrow?"

    You and your team can discover the answers to problems together. When there are no prizes or gold stars for those who get the solution first, you'll all benefit when everything turns out right.
