    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.

    When thinking about placing a human being in space, one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment. The cold of space will freeze skin in a short time. The fierce heat of the sun can cause serious burns. The lack of atmosphere can cause gases in the body to expand(扩大) and even burst. With no oxygen to breathe, a human being will die in only a few moments. Radiation from the sun is another risk in space. So is damage from small pieces of rock and objects like meteoroids (陨石).

    In 1933, an American flyer, Wiley Post, designed one of the first successful devices to protect a pilot at extreme heights. It was a large device that looked like a can surrounded the pilot's head. Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s. The clothing was similar to that invented by Wiley Post.

    Today, astronauts wear very different protective clothing. It lets them move, do useful tasks, and stay outside their spacecraft in comfort and safety for several hours. The spacesuit is called the shuttle extravehicular mobility unit or EMU. It was designed to endure longer and to permit more movement than earlier spacesuits.

    The EMU has a number of parts that an astronaut can link together by using only one hand, which makes it possible for each astronaut to select the parts that fit correctly.

    Nowadays, NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars. Because of the gravity on Mars, spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. The equipment may also have to protect astronauts from dust carried in the winds on Mars. And, they must be easy to repair and keep clean during a longer flight to and from the red planet.

    Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock {#blank#}1{#/blank#} Here is how to make one.

    {#blank#}2{#/blank#} In order to make a change, you need to decide why it's important. Do you want to get up in time to have breakfast with your family, get in some exercise or just be better prepared for your day? Once you are clear about your reason, tell your family or roommates about the change you want to make.

    Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags{#blank#}3{#/blank#} That's a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.

    Keep your sleep/wake schedule on weekends. If you're tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating (弥补) on the weekends actually feeds into your sleepiness the following week, a recent study found{#blank#}4{#/blank#}

    Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you've tried a new method for a week, take a look at your record.{#blank#}5{#/blank#} If rot, take another look at other methods you could try.

A. Gel a sleep specialist.

B. Find the right motivation.

C. A better plan for sleep can help.

D. And consider setting a second alarm.

E. If the steps you take arc working, keep it up.

F. Slick to your set bedtime and wake-up time, no matter the clay it is.

G. Reconsider the 15 minutes you spend in line at the café to get coffee.

    For those concerned about wrinkly old skin, It might be a creative solution: an elastic(有弹性的) “second skin” that can be smoothed on to make aged tissue look more youthful.

    The wearable film, developed at the Massachusetts Institute of Technology (MIT), has shown promise in a series of small experiments where it was applied to wrinkles, under-eye bags and areas of dry skin. When applied to the face or body, the thin, transparent layer sticks to the skin and supports the tissue, making it look and behave like younger skin, its producers claim.

    “What we've been able to do is create a cream that you can put on the skin, and then when it's on the skin it can actually form, essentially, an elastic second skin,” said Bob Langer, who led the research. Tests in the lab found that the polymer film (高分子膜), which is only 70 thousandths of a millimetre thick, reduced the appearance of wrinkles and under-eye bags, and helped keep moisture in areas of dry skin.

    The layer is designed to be applied in the morning, then peeled off at night. In previous studies, the second skin withstood normal daily wear, and the stresses and strains of exercise and swimming, without falling off or causing irritation. It also survived exposure to rain.

    “It's something you can wear for a whole day or longer, depending on the physical forces thatget applied to the area where it is worn, "said Daniel Anderson, who helped develop the product at MIT. “You can't tell you're wearing it.”

    While normal cosmetics can mask imperfections on the skin, the new coating changes the way skin behaves by giving it the elasticity of young skin. It was developed with help from two companies.

Study abroad

    Every year, thousands of students choose to study abroad for the summer, six months, a year or longer. Here are some things you need to know before you make such a decision.

Why do it?

    Living in another country will help you learn about the culture of another land. You will see the world in a new way. {#blank#}1{#/blank#} Many companies today want employees who speak a second language or who have experienced living or working in another country.  

Making the right choice.

    To choose the right country or school,  ask yourself these questions:  {#blank#}2{#/blank#} Do I want to live with a host family (寄宿家庭),  with roommates,  or alone?  How much do I want to pay?  

    {#blank#}3{#/blank#}

    Get your passport and visa (签证) early!  Before you go, learn as much of the language as you can, and read about the customs of your host country. Also, talk with people who have experienced studying abroad. Call the school to make sure someone can meet you when you get there.

    Once you are there.

    After the first few weeks it's usual to feel a little homesick. {#blank#}4{#/blank#}Just be open to meeting new people and having new experiences. Remember that it takes time to get used to a new place with new customs. Talk to your new friends and write about your feelings. {#blank#}5{#/blank#}

    These days, it seems like everyone wants to go out into space and live on new planets. Rather than depend on another pre-existing planet, could we make a new, proper planet ourselves?

    To start with, if we do want to be living on it, we should find a good place in space to put the new planet. We'd want it to be in a habitable zone, meaning the planet should be at the right distance from its star to make sure there would be perfect temperatures and most importantly, liquid (液态的) water.

    We'd also need the right materials to make the planet. Our Earth is made up of many different elements (元素). If we made our own new planet we'd probably want it to have similar elements and a similar structure (结构). We'd also want enough water to form some oceans.

    But even if we get all of the materials creating a new planet like Earth could have many troubles. It might be something more like a huge space station. It would be pretty expensive if we wanted it to be super big.

    We would probably also need a lot of food since there's going to be many scientists and astronauts out in space working on this project!

    According to NASA, each astronaut uses about 0. 83 kilograms of food per meal, including 0.12 kilograms of packaging (包装) material. Without the weight of the packaging material, we'd need about 780 kilograms of food just to feed one astronaut for a year.

    Putting all these together could make it possible to make our own planet one day! In reality, creating a new planet would probably require a very modern technology and there would be tons of other things to think about. And if this is even possible, it likely won't happen for a very long time.
