    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.

    As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper.

    Procrastination is the thief of time and a lot of students suffer form it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely are doing nothing either.

    Paralyzed (使失去活力) by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell (魔咒).

    According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world's population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don't delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong.

    Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is non sense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones.

    Pelling also points out that procrastination feels particularly delinquent（过失的） in a society that thinks of speedy action as admirable, and, at times, even as a moral good.

    Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is “designed” to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.

With the clicking of walking sticks and determined steps, a long line of walking group along the winding road is a fantastic sight. Almost each of the walkers is using some kind of fitness tracker. A few Fitbits, some Xiaomi wrist bands (手环), a couple of phone apps and some other pedometers (计步器) — and all, they say, are counting their steps.

    Fitness trackers are in. Sales figures for 2016 released by Internet Data Center (IDC) indicated 25% market growth compared to the previous year, with Fitbit taking the lion's share, followed by the brand Xiaomi.

    However, the wearables market has had a rollercoaster ride in recent months. Jawbone, once a popular fitness tracker brand, announced that it is leaving the consumer market. Microsoft has removed its Fitness Band on its online store although it is still available on retail (零售) giant Amazon. Fitbit remains a key brand name at the heart of the fitness tracker revolution. But it is recently reported to be cutting down on workers, and its founder James Park said it experienced “softer than expected” sales recently.

    Counting steps is probably the most common use of wearable devices (可穿戴设备), but recently experts have questioned whether the golden goal of walking 10,000 steps a day is actually worthwhile, and a US study concluded that health trackers did not aid weight loss.

Analyst Ben Wood from CCS Insight used to wear a fitness tracker on either wrist. Now, however, his concern is about users'experience — these devices don't tell you anything new after a while. There are also battery problems and many of the older and cheaper varieties aren't waterproof (防水的).

    My elephant adventures began in 1984 when, with our one-year-old daughter, my husband and I crossed the jungle in a jeep, slicking behind a lorry for comfort and company. The elephants standing like watchers on either side of the forest highway had us praying for our safety. One elephant made loud noise and angrily pawed (抓) the ground, warning us off. We raced away before they could attack.

    It was wise to keep elephants at a distance. We heard stories of tourists whose jeeps were overturned, and a couple of photographers were killed because they moved too close. Elephants are misleading animals. They give people an impression of being quiet and kind, so tourists think it's safe to picnic in the jungle (丛林). Yet angry elephants have knocked them down in seconds before they could take off.

    Elephants might make life unpredictable and dangerous. It's difficult for inexperienced environmentalists to even, begin to grasp this reality. I've heard city people say " We humans are encroaching (侵害) on their forests." But what's the solution?

    When a poor farmer borrows heavily to plant a crop, he'll do anything to protect it His life depends on it Elephants ruining an about-to-be-harvested corn field cannot expect to be welcomed like special guests. The battle between beast and farmer is violent.

    Experts are working on solutions to human-elephant conflicts (冲突). Some are sure to fail to like the plans to build electric fences around human settlements. Elephants rapidly figure them out and come in, around and over them.

    There are more questions than answers, for sure. But as my husband said, "More people die in car accidents every single day, in every city on the earth. But they won't take cars off the roads, will they?" So we need to seek practical ways of preventing elephant accidents.

    Three months after Hurricane Katrina in 2005, Rebecca Sell, then 24, a photojournalist for Fredericksburg photographed a New Orleans couple worriedly examining water-spotted photo albums. As she took the photo, something within her clicked. "I told them I could take the ruined pictures, copy them and give them digitally restored (修复) photos," she recalls. Although a bit sceptical, the couple agreed. Rebecca took their photos home, restored them and took them to the couple at their temporary home. "It felt so good to be able to do that for them," says Rebecca.

    When her editor, Dave Ellis, saw the photo of the couple, he suggested they go back and restore damaged photos for even more people. So in January 2006, with paid time off from the paper, the two set up shop in Pass Christian. After posting a notice in the community newsletter, Rebecca and Dave received 500 photos in four days. For each, the pair took a new digital picture, then used high-tech software to erase water spots and restore colors. It just so happened that a popular website linked to Dave's blog about the experience, and soon Operation Photo Rescue, as it came to be known, had emails from hundreds of volunteers, including photographers and restoration experts, eager to help.

    Though digital restoration is a painstaking process, mending irreplaceable family pictures means the world to victims like Emily Lancaster, 71, who took out piles of ruined photo albums after Katrina, never thinking the mess could be saved. But she just couldn't bear to part with a few treasured pictures, including a portrait of her father, who had passed away, and a photo of her husband as a boy. Then she heard about Operation Photo Rescue. "I didn't have a whole lot of hope they could fix them, but they did," Emily says. "Almost every day I think about all the pictures I've lost. I'm so happy to have these two."

    In the five years since Katrina, Operation Photo Rescue has collected thousands of pictures ruined by floods, hurricanes and tornadoes. Volunteers make "copy runs" to disaster areas across the country to gather damaged photos from survivors; operating costs are covered by donations. "It's great to be able to give people some of their history back," says Rebecca. "One person told me that thanks to us, her grandmother got to see her photos again before she passed away. Moments like that remind me why I do this."

I believe in the power of science fiction,not just for its capacity to transform dreams into reality, but also for its power to bond together those who share a common vision of the future. For me, that's true for my relationship with my dad. Some fathers and sons bond over sports, fishing or hunting, but my dad and I bond over Star Trek. We tried a trip to Disney World, but one of my earliest memories wasn't Mickey, but a Klingon battle cruiser（巡洋舰）on the screen.
Over the years, nearly every setting and situation has become far away for my dad and me. When it's warm at night, we're not driving along some dark streets in Indiana,but.going at a slow speed with stars dimly shining. Both of us are thinking of them,without needing to say a word. All these visions of other universes have together created a private universe for my dad and me.

Gene Roddenberry, creator of Star Trek,once said, "Science fiction is a way of thinking，a way of logic that bypasses（绕过）a lot of nonsense. It allows people to look directly at important subjects." A lifetime of science fiction has influenced more than just my relationship with my dad, but has also helped me shape my own hopes for the future.I'm now a science writer.

Yes,science fiction has made me into a nerd. And it also has been a source of joy for my family,making me an optimist while enabling me to think critically about the danger of technology.thank those authors who have shared their visions, the world and my family are better for it. Thank my dad, who is both the best storyteller and the best man i have ever known because he helped me realize the truth of Tennyson's words," since i dipped into the future,i saw the vision of the world,and all the wonders that would be.
