Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV.

    Now one American company is offering its employees a new convenience: a microchip implanted in their hands. Employees who have these chips can do all kinds of things just by waving their hands.Three Square Market is offering to implant microchips in all of their employees for free.Each chip costs $300 and Three Square Market will pay for the chip.Employees can volunteer to have the chips implanted in their hands.About 50 out of 80 employees have chosen to do so.The president of the company,his wife and their children are also getting chips implanted in their hands.

    The chip is about the size of a grain of rice.Implanting the chip only takes about a second and is said to hurt only very briefly.The chips go under the skin between the thumb and forefinger.With a chip in the hand,a person can enter the office building,buy food,sign into computers and more,simply by waving that hand near a scanner.The chips will he also used to identify employees.Employees who want convenience,but do not want to have a microchip implanted under their skin,can wear a wristband（腕带）or a ring with a chip instead.They can perform the same tasks with a wave of their hands as if they had an implanted chip.

    Three Square Market is the first company in the United States to offer to implant chips in its employees.Epicenter,a company in Sweden,has been implanting chips in its employees for a while.

    Three Square Market says the chip cannot track the employees.The company says scanners can read the chips only when they are within a few inches of them.“The chips protect against identity theft,similar to credit cards.”The U.S. Food and Drug Administration approved the chips back in 2004,so they should be safe for humans,according to the company.

    In the future,people with the chips may be able to do more with them,even outside the office.Todd Westby is Chief Executive Officer of Three Square Market.He says,“Eventually,this technology will become standardized allowing you to use this as your passport,public transit,all purchasing opportunities,etc.”

    If you ever visit an English village, make sure to look out for morris dancing. Undoubtedly one of the strangest traditions of English culture, morris dancing is a form of folk dancing that dates back to the 15th century. If you ever get the opportunity, you really have to see it.

    Men and women wearing old-fashioned, shabby clothing dance in the streets of towns and villages across the country during the holiday periods. Women wear long, frilly (有褶皱边的) skirts and men wear short trousers with bells attached to them. They dance to traditional folk music which is often played on traditional musical instruments.

    Some groups carry heavy black sticks which they beat against each other while they dance. Other groups wave handkerchiefs in the air while they perform. The dances are usually performed near a pub so that when it's over, the dancers and audience can sing some traditional folk songs over a pint of beer. The celebrations will often continue long into the night, by which point most people are too drunk to think about performing again.

    Morris dancing is a great English tradition but it's facing a big crisis. As the years go by, fewer and fewer young people are joining morris dancing groups. The dancers are getting older and older and eventually. If you've ever had the fortune to see morris dancing, you may understand why teenagers aren't rushing to sign up. Putting it to the point, it's not exactly the coolest thing for an 18-year-old to be doing. Why dress up in bells and funny costumes when you could be going clubbing? Or playing sport? Or doing anything else?

However, it would be a great shame to lose such a fun and lively part of England's history and culture. It's important to look after some traditions and customs especially when it's something as harmless and happy as morris dancing. So here's a toast to the next generation of would-be morris dancers! Let's hope they don't leave it too late.

    “Can I hug you?” community nurse Joyce Jebambula asks with a smile as she welcomes me back to her village. “Of course,” I say as I put my arms around her. It's an unbelievable moment. Just at the height of the outbreak more than a year ago, there was an “avoid body contact” rule here. It's now been removed.

    One of the most challenging parts of reporting this outbreak over the past 18 months is that I haven't been able to touch anyone in the worst-affected countries. When Ebola(埃博拉病毒) survivors described in tears describing losing their families, I had to almost sit on my hands to avoid reaching out to comfort them.

    The outbreak was declared over in Sierra Leone on 7 November. I returned for the celebrations. But despite reaching this long-awaited milestone, all is not well.

    Ibrahim Koroma, 21, clings to (紧紧抓住) his survivor's certificate (证明) outside the home. All 17 of his family are now dead. The certificate is one of his most prized possessions. "He does not pose any risk to the community" it reads.

    Ibrahim tells me how his landlord has allowed him to stay in one of the rooms of his former family home until the end of the year. He says he doesn't know what he'll do after that. He does some part-time work, relying heavily on help from neighbors. His two little sisters and little brother died in the very room where he now sleeps. He says he often lies awake thinking about them, feeling very bad.

    The Ebola outbreak in West Africa was the worst on record. In past outbreaks there had only been a few hundred deaths and a few hundred survivors. It was thought Ebola could live for only three months. But research has now shown it can linger for at least nine months. Scientists are still trying to find how long it could be infectious.

    Finland is the happiest place on Earth, according to the 2018 World Happiness Report of 156 nations.

    The report, released Wednesday by the United Nations' Sustainable Development Solutions Network, ranks the countries of the world based on six different categories of well-being: income, freedom, trust, life expectancy, generosity and social support. This year's report also pays special attention to the happiness of each country's immigrants.

    The U.S. dropped four spots from 2017 and landed in 18th place, and last year's winner, Norway, came in second place — followed by Denmark, Iceland and Switzerland.

    "The top five countries all have almost equally high values for the six factors found to support happiness, and four of these countries—Denmark, Switzerland, Norway and now Finland — have been in first place in the six World Happiness Report rankings since the first report" in 2012, "co-editor John Helliwell told CNN. "In a division with such excellent teams, changes in the top spot are to be expected."

    Rounding out the top 10 happiest countries was Canada in sixth place, then New Zealand, Sweden and Australia. The order of the top 10 nations changed from the 2017 list but the countries did not, according to the report. They were also 10 of the 11 top spots in the immigrant happiness category (including Mexico — 24th overall, but 10th in immigration).

    "The most striking finding of the report is the remarkable consistency between the happiness of immigrants and the locally born," Helliwell said in a statement. "Although immigrants come from countries with very different levels of happiness, their reported life evaluations resemble those of other residents in their new countries. Those who move to happier countries gain, while those who move to less happy countries lose."

    Other major world powers placed in significantly low spots on the list. Germany came in 15th, the UK was 19th — followed by Japan in 54th place, Russia in 59th and China in 86th.

    The report, based on surveys completed by citizen volunteers, came just under a week before World Happiness Day on March 20, when the UN declared to recognize "the relevance of happiness and well-being as universal goals and aspirations in the lives of human beings around the world and the importance of their recognition in public policy objectives".

    OK, so it's not a real war but the U. S. and China are at the beginning of a trade war thanks to President Trump's policy. The Chinese government raised $34 billion in new duties on goods exported from the U.S. last week in answer to President Trump's unwise tariffs(关税) of $34 billion on Chinese goods.

    Farm and seafood-producing states are going to be hit hardest by China's new tariffs on U. S. goods. States where cars are made and shipped to China are on the hook as well.

    In terms of value, some 38 percent of products on the tariff list are agricultural, including soybeans, sorghum, tobacco and meat. That's nothing like good news for farm-belt states, primarily in the Midwest like Iowa.

    A wide range of seafood is on China's tarifflist. That could hurt fishery workers in Alaska and lobster(龙虾) harvesters in Maine. Alaska, for example, exported nearly $lbillion worth of seafood to China. "China is a major market for Alaska seafood," said Alexa Tonkovich, Executive Director of the Alaska Seafood Marketing Institute. "The seafood industry directly employs nearly 60,000 workers in Alaska each year and directly employs more workers than any other private industry."

    And automaking States, particularly in the South, are also at risk. Some 24 percent ofproducts on the list- in terms of value-are cars, trucks and other vehicles. Michigan alone exported $1.7 billion worth of motor vehicles and vehicle parts to China in 2017. Other states being affected include South Carolina, where BMW makes SUVs for both the U.S. and export, and Alabama, home to Mercedes-Benz, Toyota, Honda and Hyundai factories.

    This round of tariffs spares some industries, like commercial aircraft. Washington State could breathe a sigh of relief, which is home to Boeing. It also, for the moment, skips tariffs on chemical products.

    Alexa Tonkovich has warned the U.S. government that the trade war could risk jobs, reduce industry profits, and cause higher prices for consumers in the U.S!

China's Tianwen 1 Mars probe (探测器) conducted its fourth orbital correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.

The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布) the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Tianwen I has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and I. I million km from Mars. Depending on the two planets' orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen I is seen in its first selfies in space on Oct. 1, 2020. The administration also published a black-and-white picture of Mars taken by Tianwen I, the first snapshot (抓拍的照片) from the Chinese craft.

Tianwen I, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

A successful landing would make China only the second nation to place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署) a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.
