Nothing could stop Dad. After he was put on disability for a bad back, he bought a small farm in the country, just enough to grow food for the family. He planted vegetables, fruit trees and even kept bees for honey.
          And every week he cleaned Old Man McColgin's chicken house in exchange for manure(肥料). The Smell really burned the inside of your nose. When we complained about the terrible smell, Dad said the stronger the manure, the healthier the crops, and he was right. For example, just one of his cantaloupes filled the entire house with its sweet smell, and the taste was even sweeter.
          As the vegetables started coming in, Dad threw himself into cooking. One day, armed with a basket of vegetables, he announced he was going to make stew(炖菜).Dad pulled out a pressure cooker and filled it up with cabbages, eggplants, potatoes, corns, onions and carrots. For about half an hour. the pressure built and the vegetables cooked. Finally, Dad turned off the stove, the pot began to cool and the pressure relief valve sprayed out a cloud of steam. If we thought Dad's pile of chicken manure was bad, this was 10 times worse. When Dad took off the lid, the smell nearly knocked us out.

          Dad carried the pot out and we opened doors and windows to air out the house. Just how bad was it? The neighbors came out of their
houses to see if we had a gas leak!
          Determined, Dad filled our plates with steaming stew and passed them around. It didn't look that bad, and after the first wave had shut
down my ability to smell, it didn't offend the nose so much, either. I took a taste. It would never win a prize in a cooking competition,
but it was surprisingly edible and we drank up every last drop of soup.

    If ever a drink were invented to satisfy the thirst of social media, this may be it.

    With its fantastic name, bright pink and blue twist topped with a pillow of whipped cream, Starbucks' new Unicom Frappuccino(独角兽星冰乐) practically asks to be posted on social media.

    And a glimpse at Twitter shows Unicom Frappuccino is indeed gaining attention.

    So what's in it? As Starbucks describes it: “A sweet dusting of pink powder, mixed into a Frappuccino with mango syrup and layered with a pleasantly sour blue drizzle. It is finished with vanilla whipped cream and a sprinkle of sweet pink and sour blue powder topping.”

    A look at the ingredients reveals a list less fantastic. The pink powder is actually sugar and "Fruit and Vegetable Color.”

    Starbucks advertises the drink “^,as rare as a unicorn." But unicorn food is actually a thing. The BBC reports, it's fashionable to post pictures of rainbow colored food which reminds of the fairy tale creature.

    Rainbow sushi, anyone?

    As for the Unicorn Frappuccino, Lori Aquino said the drink caught her eye on social media. Then people at work were talking about it. “I saw it was coming out today, so I decided to try it,” Aquino said at a Washington D.C. Starbucks. “I'll probably put it on Snapchat or Instagram.”

    She bought one to share with her two coworkers.

    And the opinion?

    “It's kind of nasty,” Aquino said.

    Letitia Winston agreed: "Nope. That will not be something I come looking for."

    But Moriam Animashaun was more forgiving. "It's not bad,” she said, “It's just really sweet.”

    A 16-ounce medium, or a grande in Starbucks speak, comes in at 410 calories, 59 grams of sugar and 16 grams of fat.

    One thing the women agreed on was the drink's appearance. “It's pretty," said Animashaun.

    “It looks nice," agreed Winston.

    And in the age of likes, snaps and tweets, the fantasy image may be all that matters.

    The Unicom Frappuccino is available April 19 through April 23 at participating stores in the United Stales, Canada and Mexico.

    Breathing in polluted air on busy roads is as harmful as passively smoking ten cigarettes a day, new research has found. The drop in pollution had the same effects as avoiding four cigarettes a day. One of the researchers, Saskia van der Zee, explained why they compared the effects of pollution lo passive smoking. “We thought that passive smoking would be easier to understand,” she told The Times. "You don't want your neighbors to come into your house and smoke three cigarettes every day."

    Earlier this week, doctors warned that Britain is facing a major health emergency unless diesel(柴油)cars are taken off the roads. Emissions (排放物) from diesel cars arc already contributing to smog which has been linked to the deaths of 40,000 people a year. Health charities, medical leaders and environmental groups have called for a modern Clean Air Act lo bring pollution under control. Separately, more than 300 doctors in the Doctors Against Diesel group have written to Theresa May, calling for a diesel reduction.

    Professor John Middleton, president of the UK Faculty of Public Health, said, “Diesel is the primary source of nitrogen dioxide(二氧化氮)in urban areas and is linked to health effects that begin before birth and extend throughout life, from childhood lung development to increased risk of heart disease, stroke and lung cancer. It is high lime lo handle the problem.”

    London is already planning to introduce an “emission zone” which diesel drivers would be charged to enter, and other cities are set to follow. But exerts are desperate to find new ways to control the damage done by pollution. Diesel drivers in Westminster have been told they may soon be charged 50 percent extra for on-street parking. And Sadiq Khan, the mayor of London，submitted a £ 3,500 plan to encourage drivers to switch to petrol or electric cars.

    “Cutting diesel emissions would therefore have an immediate effect on children's personal exposure, and improve their long-term health.” A government spokesman said.

    Angad Rekhi, a graduate student and an assistant professor of electrical engineering, has developed a wake-up receiver. This wake-up receiver has many potential applications, particularly in designing the next generation of net worked devices, including so called "smart" devices that can communicate directly with one another without human intervention (介入).

    Once attached to a device, a wake-up receiver listens for a unique ultrasonic（超声波）pattern that tells it when to turn the device on. It needs only a very small amount of power to maintain this constant listening, so it still saves energy overall while extending the battery life of the larger device. A well-designed wake-up receiver also allows the device to be turned on from a significant distance.

    Given the increased interest in networked devices, researchers and industry organizations are starting to define what features and techniques will become standard. Regardless of whether this ultrasound wake-up receiver is among these standard designs, it is likely wake-up receivers of some kind will be combined into commercial applications soon.

    By comparison, the ultrasound wake-up receiver requires a battery but has much greater range than the wirelessly powered devices, while still maintaining a long lifetime due to extremely low power draw. These two technologies-wireless power and wake-up receivers-would likely serve different purposes but both indicate at a turning point in devices that make up the Internet of Things.

    "In light of a long-promised future where interconnected, autonomous, widespread and unremarkable technologies make life easier, the networked devices available now, like video doorbells and app-enabled lights, seem like rather slight advances." the researchers said. They believe technologies like theirs could help cross the gap between the Internet of Things as we know it and the Internet of Things at its best-whatever that may be.

    All over the world, children in hospital are being treated with a new kind of medicine：Laughter. Lucy is 23 and works for Theodora Children's Trust. She is one of many clown (小丑) doctors who bring a smile to the faces of sick children.

    “I'm a Theodora clown doctor. I call myself Dr Looloo. I spend two days a week in children's hospitals, making funny faces, telling jokes, and doing magic tricks. As I walk into the wards(病房) I blow bubbles, shake hands with the kids, and make up nonsense songs for those children well enough to sing. I take special balloons to make 'balloon animals' and tell funny stories about them.

    I'm naturally a very cheerful person. I've always been a clown. In fact my father's a clown and I started working with him when I was eight years old. I knew it was just the job for me and I became a clown doctor because I think it's a great way to cheer up sick, frightened children in hospital.

    Being a clown in hospital is very tiring both physically and emotionally. We have to learn not to show our feelings, otherwise we'd be useless. Clown doctors are sensitive but this is not a side most people see. To the children we're happy all the time. I'm still learning to allow myself to feel sad occasionally. There working with a very sick little girl from Bosnia who speaks no English, so our only common language is laughter.

    At weekends I participate in events to raise money for Theodora Children's Trust. It's a charity, so we are paid with the money people give. Being a clown doctor makes the worries of everyday life seem small. All in all I feel honoured to do this job.”

    It is a live celebration of the lasting power of letter writing!

    Letters Live, which started in December 2013, was held at the Freemasons' Hall in London from March 10 to 15. The show invited various great performers who read remarkable letters that had been written around the world over the centuries.

    "Bringing letters alive through outstanding performances is one of the most powerful ways in which the joy and pain and humor and tragedy of being human can be shared," Jamie Byng, managing director of Canongate Books publishing firm, told the Nowness video channel.

    British actor Benedict Cumberbatch agreed. "Letters are windows into the love, beauty, pain and humor of their creators and receivers," he told The Guardian. "Letters Live makes us stop and imagine the lives behind the letters read and where they came from. It's a great honor to read this most ancient of communications live to an audience."

    This year, the movie Sherlock star treated the audience by playing the part of a 17-year Tom Hanks. He put on the young actor's voice when he read his letter to the Hollywood director George Roy Hill, a letter that urged Hill to "discover" him. The letter showed that two-time Oscar winner Hanks' teenage dream was not to "be a big-time Hollywood superstar" but to one day own a Porsche car and call his favorite US actor Robert Redford his nickname "Bob".

    Other famous faces at the event included Carey Mulligan, who played a fictional laundry worker, a female activist fighting for women's rights in the 2015 movie Suffragette. The British actress once again played the role of a suffragette (女权主义者), when she read a very enthusiastic letter demanding the vote for women. The suffragette sent a precious 1913 note to The Daily Telegraph newspaper.

    “Everyone seems to agree upon the necessity of putting a stop to Suffragist anger, but no one seems certain how to do so, " Mulligan read out. "There are two, and only two, ways in which this can be done. Both will be effectual. One, kill every woman in the UK. Two, give women the vote."
