The poaching（偷猎）, or illegal killing, of rhinos(犀牛) in South Africa is growing worse each year．The government recently reported that a record number of rhinos were poached in 2015，a year which had more rhino killings in South Africa than ever before.

    The World Wildlife Fund，or WWF，says about 20, 000 rhinos live in South Africa．That is more than 80 percent of the rhinos in the world．Edna Molewa，South Africa's Environment Minister，says, “During 2015，we are sad to say this，1,215 rhinos were killed．This is a rise in the number of poached rhinos from 1,004 in 2014 and indeed very worrying.”

    The animals are hunted for their horns(角)．Many people in Asia believe the horn has curing power，which drives poachers， at all costs，mad for more horns． But there is no scientific evidence for this belief．The horn is made of keratin(角蛋白)．That is the same thing as human hair，fingernails and toenails.

    Ms．Molewa said 386 suspected poachers were arrested last year，an increase from the year before．But rhino protection workers say poachers often go unpunished after arrest． South Africa's legal system is ineffective． Ms． Mo1ewa said more needs to be done and South Africa is taking strong measures to protect rhinos．The efforts include moving some of the animals to secret places in neighboring countries. “Now approximately 100 rhinos have been moved to neighboring states in the SADC region during 2015 and 200 more rhinos will be moved this year,” Molewa said.

    Jo Shaw，the rhino program manager at the WWF，said， “We're talking about a loss of a hundred rhinos a month，or more than three a day．We really need to see effective action not just at a national level but internationally．” She says officials should find the criminal groups responsible for the poaching and punish them. Government officials are to meet in Botswana in March at the Inter-governmental Conference on Illegal Wildlife Trade.

    Parents may think they're smart about where they store medicines, but their kids are smarter. Nearly 60,000 young children are rushed to the hospital every year after getting into medicines not meant for them, according to a new report from Safe Kids Worldwide.

    The report finds little connection between what parents know about storing medicines safely and what they actually do. Nine out of 10 parents know that medicines should be stored up and away out of reach and sight, but 7 out of 10 of them admit not doing that. They leave medicines out on kitchen counters, sinks and sofas, believing babies and toddlers(学步者)aren't tall enough or strong enough to reach them. Unfortunately, they probably can. Children as young as a month have ended up in an emergency department because they'd been poisoned by getting into a medicine that was left within reach.

Most poisonings related to medicines—particularly among babies and toddlers—occur within their home. Kids develop rapidly and they want to explore their environment. At certain ages they have a lot of hand-to-mouth activity, and so it's very common for them to explore their environment and then try to taste what they find.

    The new Safe Kids worldwide report includes a survey of 2,000 parents with children under age 6. While the number of children visiting an emergency department for accidental poisonings had declined since the 2010 maximum, the decline has slowed in recent years.

    Prescription and over-the-counter medicines cause the most severe poisonings, but vitamins and supplements(补充品)can also cause problems. There are steps families can take to lower the risk for an accidental medicine poisoning.

    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.

    One cold day in winter, my wife and I were walking back home from the grocery store as usual when we suddenly decided to walk into a coffee shop.

    My wife ordered a coffee at the counter. Just then, I saw a young woman in her thirties helping with a rather weak Mexican woman into the shop. Maybe it was the gentleness of their difficult experiences or an unclear familiarity (熟悉) with the situation that drew my full attention. I immediately had a strong wish to do something for them. Unfortunately, before I could think of anything reasonable to say, they left the coffee shop without ordering anything!

    When my wife returned, I told her about the two women and said," I missed the chance to do something for them." Strangely enough, though, they came back into the same coffee shop five minutes later. Unbelievable!" This is my chance," I thought out loud as my wife shared some creative possibilities. The two women ordered, took their place card and left the counter.

    After quickly finishing our coffee, we walked up to the counter and asked the smiling cashier (出纳员),"What is your most popular dessert (甜点)?" Chocolate Cake," she answered. With a childlike feeling of happiness, my wife made an unusual order." Can I buy a chocolate cake for the two women who were here just before us? But don't tell them it is from us. Just give them this card," she said while taking out a smile card. The cashier couldn't believe it." Do you do this all the time?" she asked." Not all the time, but just whenever the heart calls for it," I answered with a natural smile.

    We, my wife and I, are people of middle income (收入). That night, we had planned to have our once-in-a-while dinner at a restaurant. But walking out of that coffee shop, both of us stood upright and said," Let's eat at home today." It's more filling (能填饱肚子的) to give a chocolate cake than to eat it.

    A campaign is being launched to encourage children to surrender 30 minutes of screen time a day to head for the great outdoors.

    The newly formed Wild Network—a collaboration of nearly 400 organizations—is attempting to attract youngsters away from television and computer screens to fields, woods and parks. Members of the network include the National Trust, RSPB, Play England and the NHS. Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general well-being.

    A documentary film, Project Wild Thing, will forecast the launch at more than 50 cinemas across the UK from Friday. It looks at the increasing link between children and nature.

    Andy Simpson, chairman of the Wild Network, said, "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation. Time spent outdoors is decreasing, roaming (漫步) ranges have fallen largely, activity levels are declining and the ability to identify common species has been lost."

    Suggestions on how to get more time in nature include collecting conkers (七叶树果), camping, snail racing, and observing autumn colour on trees.

    From January, the network will aim to make suggestions on how the government can do more to get children muddy and bright-eyed.

    This is not the first time the message of less screen time, more play has been brought up. Children in the 1980s were requested to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off the TV set and go to do something less boring instead".
