I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled (贴标签 ) everything. I always looked for everything. Over time, Kate got nearer and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

    War broke out one evening. Kate came into the room. Soon, I heard her screaming, "Take your shoes away! Why under my bed!" Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.

    The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled (爬) under her covers, sobbing.

    Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart. Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn't notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me. "Thanks."

    Kate and I stayed roommates for the rest of the year. We didn't always agree, but we learned the key to living together: giving in cleaning up and holding on.

    Don't you just hate it when you have to take an important phone call and you're surrounded by potential eavesdroppers(潜在偷听者)? You either have to whisper or go outside to keep the conversation private, which is not good. Now Hushme aims to fix this problem by muffling your voice and making you look like Bane in the film Batman.

    Hushme is a strange high-tech mask(口罩)that blocks the sound of the wearer's voice so that people nearby can't hear what is being said. It connects to your phone via Blucetooth and comes with a pair of earphones. When you get a private call, all you have to do is put the mask on and it will do the rest. The pair of thick pads over your mouth does a good job of muffling your voice, but to ensure nothing gets through. Hushme also has speakers that play a variety of sounds when you speak.

    The Hushme mask, which comes in a variety of colors, can be worn around the neck, like a regular pair of earphones, and attaches in front of your mouth thanks to a couple of very powerful magnets(磁铁). It's not yet clear how comfortable speaking with this Bane-like mask over your mouth really is, or how effective its speech muffling ability is, so we know so far is that it makes you look strange. The sound choices for covering your voice currently include wind, ocean, rain, birds, monkey, but new ones could be added in the future.

    Advertised as the “world's first voice mask for mobile phones'. Hushme was showed at CES. At the becoming of this year. Its makers plan to sell it by the end of this year. It will cost about $200.

    For teenagers, it's great fun to explore new places and it feels like an adventure, even when you know you're not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.

    ◆Do the map reading if you're being driven somewhere. It'll be easier if you keep the map following the direction you are traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat.

    ◆Get a group of friends together and go exploring. You'll need a good map, a compass, a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies. Tell someone where you're going before you set out and let them know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

    ◆See if your school or a club organizes orienteering(越野识途比赛) activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B(and B to C, etc. ) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compass and gain some special skills. In some way, it's not only good fun, but also a great way to keep fit.

    Boomerang children who return to live with their parents after university can be good for families, leading to closer, more supportive relationships and increased contact between the generations, a study has found.

    The findings disagree with the research published earlier this year showing that returning adult children trigger a significant worsening in their parents' quality of life and wellbeing.

    The young adults taking part in the study were "more positive than might have been expected" about moving back home – the shame is reduced as so many of their friends are in the same position, and they acknowledged the benefits of their parents' financial and emotional support. Daughters were happier than sons, often getting back easily to teenage patterns of behavior, the study found.

    Parents on the whole were more uncertain, expressing concern about how they can arrange and manage it if their children continue to live with them. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.

    The families participated in the study were middle-class and were more likely to view the achievement of adult independence for their children as a "family project". Parents accepted that their children needed support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out or even afford their own house.

    "However," the study says, "many parents and a little over half the graduates report day-to-day tensions (矛盾) about the prospects of achieving adult independence, which in a few extreme situations came close to conflict".

    Areas of disagreement included housework, money and social life. While parents were willing to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.

PhoneSoap: Charge and Clean Your Phone

    You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won't surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them—specifically, the bacteria called E.coli.

    The research on bacteria and viruses led to the invention of PhoneSoap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges.

    "There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones," says Wes Barnes, the PhoneSoap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. "He realized he got the idea of getting rid of bacteria and viruses on the phones," said Barnes. "In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines."

    PhoneSoap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you'd plug it into the PhoneSoap charger box. The process only takes a few minutes but, Barnes says, "The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully."

    The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week's International Consumer Electronics Show in Las Vegas, PhoneSoap was all grown-up. Both co-founders have left their previous jobs and are selling PhoneSoap nonstop. "We're shipping almost more than we can handle each day," Barnes says. "It's been a great adventure."

The hardest thing about planning a big European vacation is actually narrowing down where to go—there are just so many amazing places. That's why we've put together what we think are the best cities in Europe. 

AMSTERDAM, NETHERLANDS

Amsterdam is the kind of city that you can't help but fall in love with. It's the kind of place where you dream about moving and buying an apartment that overlooks (俯瞰) a peaceful river. It's relaxing and you get a sense that the locals have an amazing quality of free life. We love simply walking around the canals and exploring the city's neighborhoods. 

BERLIN, GERMANY

Berlin is said to be "poor but charming" and we think that's a pretty good description. Actually, Berlin is becoming more expensive as its popularity grows, but it's still the top spot for Germany's artistic scene. Berlin isn't particularly pretty but it's an energetic city with cool people and cooler graffiti-covered (涂鸦) neighborhoods. 

LISBON, PORTUGAL

Lisbon is a hot destination and I doubt it will be quickly moving up in the ranks of Europe's most visited cities. Lisbon is a popular coastal city that's famous for its unique buildings and charming café culture. It's also very friendly on the wallet when compared to other Western European cities—food and lodging are both priced reasonably and attractions are about average. 

FLORENCE, ITALY

Florence may be touristy but that's no reason to ignore this birthplace of the Renaissance (文艺复兴). If you do your research, you can find plenty of excellent Italian restaurants and world-class ice cream. And, of course, the city is beautiful and home to top museums so it's a dream for art and history lovers.
