One of the most popular and enduring myths about depression is that depressed people are sad all the time—and that by extension, people who are happy can't be experiencing depression, even if they say they are. It is a mistaken version of depression. Depression doesn't make you sad all the time.

    When I'm having a depressive feeling, I'm not walking around in black clothes, and weeping. I go out with friends. I play jokes. I keep working, and have friendly chats with the people I work with. I read books. Above all, I experience moments of happiness. Yet I feel a strange conflicting pressure. On the one hand, I feel like I need to engage in a sort of sadness for people to understand that I really am depressed and that each day is a struggle for me. Because that way I will appear suitably sad, and thus, depressed—and then maybe people will recognize that I'm depressed and perhaps they'll even offer support and assistance.

    On the other hand, I feel an extreme pressure to perform just the opposite, because sad depressed people are boring and no fun, as I am continually reminded every time I speak openly about depression or express feelings of sadness and frustration. I'm caught in a trap where if I don't perform sadness, I'm not really depressed, but if I express sadness at all to any degree, I'm annoying and boring and should stop being so self-centered. Depression can become your master, but you can slip out from under it occasionally. And many depressed people don't actually spend it fainting dramatically on the couch and talking about how miserable they are.

    A “virtual (虚拟的) cocktail” glass that lets you change the flavor (味道) of your drink using your Smartphone has been developed by scientists.

    Offering a customizable (定制的) range of drinks and tastes, the Vocktail can change a glass of water into a cocktail at the press of a button. The world's first technology tricks your brain into thinking it is experiencing a specific flavor by fooling your senses of sight, smell and taste.

    Developed by researchers at the National University of Singapore, the glass' three sensory components are controlled via a Smartphone App. Because the software can combine a number of smells, colors and tastes, the Vocktail can create almost any flavor.

    Developer Nimesha Ranasinghe said: “Our approach is to increase drinks flavor experience by overlaying outer sensory stimuli (刺激物). For example, in the Vocktail we overlay color, taste and smell sensations to create an adjustable flavor experience. Flavor is mainly how we feel food and that is achieved through the use of these senses. Therefore, by changing the color of the drink, using different smells and changing the taste through electricity, we are able to copy the flavor of a drink without it actually changing the liquid.”

    The glass houses three fragrance containers connected to micro-air pumps. The pumps release smell that change your feeling of the drinks, flavor. For example, a lemon fragrance will trick your brain into believing it is tasting lemon-flavored drink.

    On the outside edge of the glass are two electrode strips (电焊条) that send electric pulses into your tongue to stimulate your sense of taste and flavor differs with different pulses.

    One of the hardest parts of living abroad is being away from your loved ones, especially your family. While my friends are so important to me, I've personally found it more difficult being away from family.

    However, I was fortunate that my mum and sister recently found the time to see me. Both my sister and I have major birthdays this year as she's tuming 18 and I'll be 21. My sister is a very big music fan and this year, I created my status as the best older sister by keeping an eye out for music concerts in Paris. In our home town of Leicester, we don't regularly get many well-known artists playing in our city. But in Paris, I managed to get the best 18th birthday present of all: tickets for all three of us to see my sister's favorite American rapper, Angel Haze.

    I will try to visit for my sister's actual birthday in June, the chance for my sister and my mum to visit became a birthday treat. The experience of finding our way together to the concert or getting to show them around the Paris sites such as the Eiffel Tower,the Arc du Triomphe and even my favorite ice cream place,Amorino, was an amazing memory for us all !Despite the fact that I felt the slight pressure to make sure the weekend went smoothly,even the heavy rain failed to dampen our mood.

    Therefore, while it can be difficult being away from home and potentially missing big family moments,there are ways to avoid the sadness and find a way to make the best of your situation to create an unforgettable memory. Just like the continuing rain while we went up the Eiffel tower, every cloud has a silver lining, because then we got the funniest photos ever!

    These days, young people in some English-speaking countries are speaking a strange language, especially when communicating on social media.

    Look at these words chosen by The Washington Post: “David Bowie dying is totes tradge,” and “When Cookie hugged Jamal it made me totes emosh.” Or this sentence: “BAE, let me know if you stay in tonight.”

    What on earth do they mean? Well, “totes” is a short form of “totally”. Similarly, “tradge” means “tragic” and “emosh” means “emotional”. It seems that, for millennials（千禧一代）, typing in this form is not only time-saving but fashionable.

    As you can see, many millennial slangs（俚语）are formed by so-called “totesing”—the systematic abbreviation（缩写）of words. The trend might have started with “totally” becoming “totes”, but it now has spread to many other English words.

    The origins of other millennial slangs are more complex than “totesing”.“Bae”, for example, has been widely used by African-Americans for years. It can be an expression of closeness with one's romantic partner or, like “sweetheart”, for someone without romantic connection. After pop singer Pharrell used the word in his work, “bae” became mainstream.

    Some people might think millennial slangs lower the value of the English language, but Melbourne University linguist（语言学家）Rosey Billington doesn't agree. She says when people are able to use a language in a creative way, they show that they know the language rules well enough to use words differently. Two other linguists, Lauren Spradlin and Taylor Jones, share the same view. The two analysed hundreds of examples of totes-speak and discovered totesing has complex roots.

    It isn't simply an adult version of baby talk, nor a clever way to minimize your word count. Rather, it is a highly organized system that relies on a speaker's mastery of English pronunciation. It is about sounds, follows sound system of English and has strict rules.

    Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.

    Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.

    Do you know what a "territory" is? A territory is an area that an animal ,usually the male, claims(声称)as its own .Only he and his family are welcome there. No other families of the same species(物种)are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.

    If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time ,especially at nesting(筑巢)season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird's song, and it is usually enough to keep an outsider away.

    Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.

    You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.

    The "Give It Up for Earth Day" encourages people to commit to giving up actions that are harmful to the environment, such as using poisonous cleaners.

    Throughout the month of April, Canadians are being asked to "Give It Up for Earth Day!" Earth Day has been celebrated every year on April 22 since 1970. Earth Day Canada president Jed Goldberg says that as people become more environmentally aware, they want to find ways to reduce their environmental influence, not just celebrate one special event.

    "Earth Day is a great launching pad for thinking about environmental action every day," said Goldberg. "Choosing healthier options, even for the short term, can lead to thinking about the influence of our decisions for a lifetime."

    That's the reason behind the "Give It Up for Earth Day" campaign. It's designed to encourage healthy habits that benefit people and the planet. It challenges everyone to help create a healthier world by making changes in their daily routine.

    "We wanted to plan an action—targeted campaign that will give people a chance to act on their concern for the environment in a positive way," said Goldberg.

    The campaign has identified four daily actions that can add up to huge environmental savings. They include pledging (保证) to turn off the TV, give up the use of poisonous cleaners, reduce consumption of consumer products and cut out meat.

    At the end of April, all of the pledges will be recorded and converted (转化) into the number of TV hours not watched, dollars not spent on unnecessary items, electricity saved, greenhouse gas emissions (排放) avoided by cutting out meat, and poisonous chemicals produced from homes and landfills.

    "What we're trying to achieve this year for Earth Day is to give people a chance to do something that is meaningful and measurable," said Goldberg.
