A typical school day in the UK starts around 8:30 am. This is often even earlier elsewhere in the world, with students sitting down to their first lesson at 7:30 am in the US. The average teenager ideally needs eight to nine hours' sleep each night, but in reality a lot of teenagers struggle to get this much. A lot of the problems arise because our sleep patterns are not fixed, and they change as we grow.

So a later school start time could help to solve this problem, by ensuring to get their eight plus hours of sleep and react properly to their body's natural rhythms (规律). There has been a general shift over the past 25 years to shorten the school day. This is not at the cost of teaching time (which has remained constant) but at the cost of natural breaks, which has led to reduced lunch time and lesson breaks.

Later start times could help teens' grades and health. This is mainly because it makes the management of children easier. Supervising (监管) hundreds of children “playing” requires effective staffing (人员配备). And there is always the fear that behavior worsens during breaks. So the theory goes that having them in class and strictly supervised must be better.

    But this means that students barely have enough time to absorb what they were doing in maths before suddenly they are thrust into ancient history. And teaching staff also transit from one class to another, with hardly a rest or time to refocus.

    Clearly rethinking the school day could benefit everyone involved. Anyway, it could also lead to better achievement in teenagers and less of a struggle for parents in the mornings. For teachers, it could also mean a less stressful day all around and what could be better than that?

For your next out-of-this-world vacation, you now have the option of literally going out of this world—-but it'll cost you $ 40 million. Then again, can you really put a price tag on having the time of your life? According to a new report from Popular Mechanics, Russia is looking to build a luxury hotel in outer space. There you will wake up to a breathtaking blue planet—--the earth! The hotel is expected to be stationed on the International Space Station (ISS).

While space tourism itself isn't exactly a novel idea, the notion of building a hotel out there hasn't been raised before. Really, other companies are still focused on the transportation part of the puzzle—-after all, a trip to space is enough for most folks.

    According to Popular Mechanics, the hotel will include a luxury orbital suite with big windows, personal hygiene(卫生) facilities, exercise equipment, and yes, WiFi. Because if you can't share your experience on social media, did it really even happen?

    Of course, the reasons behind the hotel aren't just for fun and games. Apparently, space tourism might be able to help the Russians pay for another module to add to the International Space Station. Russian space contractor RKK Energia is currently building the first such module, which will give scientists a laboratory and power supply station from which to conduct tests.

    If any of this is going to happen, however, Russia is going to have to hurry. With the ISS expected to be out of use in 2028, there's little time to build the hotel and find wealthy tourists to actually buy a trip into outer space.

    So if you've recently come into a fortune and are interested in what could be the time of your life, ISS is calling your name.

    The world's first subway was built in London in 1863. At the time, the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work, they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems, the idea of the London Underground, the first subway system, was born.

    The plans for building the Underground met with several problems and delays, but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30，000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed), and pleasant decorations inside each of the cars. However, the smoke from the engine soon filled the air in the tunnels(隧道) with ash and soot(煤灰), as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems, riding in the Underground did catch on. It carried 9 million riders in its first year.

    A few years ago, bubble tea(奶茶) exploded as a popular drink for Internet foodies(吃货) everywhere. Many take this Taiwanese drink as a guilt-free snack similar to juice or a cup of coffee. After all, it has the word "tea" in it, so it has to be healthy…right?

    Not quite. Like coffee, bubble tea's ingredients(成分，配料) might not be so bad on their own, but when they're loaded with sweetener(甜味剂) and artificial flavor(人工香料), they lose their nutritional (营养的) value fast.

    It all starts with those "bubbles" found at the bottom of your drink, which are actually round pieces of tapioca(木薯淀粉). Called "tapioca pearls(珍珠)," they're actually made from a vegetable that grows in South America. And as it turns out, those little balls are loaded with sugar—and not the nutritious, fiber-rich(富含纤维) kinds found in whole grains(全麦类), either.

Cooking tapioca pearls only makes it worse. They're typically fried in hot water, along with even more added sugar, for up to three hours. By that point, these balls could have nearly 160 calories per ¼ cup.

    And don't even get us started on what comes in the extra syrups(糖浆). Thanks to all those processed(加工的) ingredients, the average bubble tea can easily reach 300 to 400 calories per cup!

    On top of being an unhealthy habit, bubble tea could even shorten your life. In 2012, a group of German researchers from the University Hospital Aachen reportedly found aspolychlorinated biphenyls, or PCBs, in tapioca ball samples. These cancer-causing chemicals have also been shown to have other bad effects on the immune(免疫), reproductive(生殖), and nervous systems.

    You might want to lay off your bubble tea addiction. Thankfully, we have a few choices for low-calorie, healthier drinks, instead.

    "Mom, what is that?" asked my son. "The Bride of Chucky?"

    The old doll I was holding was pretty scary. Her glass eyes were especially horrible, closing when she stood upright and flying open when she lay flat. Once she had been loved, but she had been stored in an attic (阁楼) for decades, where the extremes of heat and cold can be hard on a girl's looks. Throw her in the waste bin? Maybe. But first, let's check eBay.

    I clicked, supplied the required information about condition, including defects (i.e., "Only a miracle could save this doll"), and uploaded its photos. I sold it for $5.

    The buyer was happy: "As described!" he wrote on my feedback page. "Super seller!" The doll found a home and, I hope, a new life. Maybe she was used to repair other dolls. Perhaps those strange eyes got fixed and once again can inspire a child's love. It's a win-win, if you ask me.

    I also sold lots of other stuff. None of them brought in a lot of money, though I have been surprised at the occasional bidding war, like, for example, the one over an old swimsuit that would have made Brigitte Bardot look bad. And some customers, let's face it, are strange. Recently I had a hard time convincing an Australian would-be buyer of an Irish souvenir bell that I don't shop internationally; it's just too much trouble. He could have flown to Ireland and bought his own bell for the price he was willing to pay. Another time, a buyer complained that the electric wire on an old radio was dirty. Really? Dirty? The wire was black. But I aim to please, so I offered a refund.

    So why bother with the dealing and small profits? Because I don't like abandoning the past. All these treasures once had stories. They meant something. But the people who gave them that meaning are gone, and I simply cannot rescue everything. I can't even sew. So I find it satisfying that a new owner, discovered via eBay, will continue the story in his or her own way.

    Many youths want to learn how to drive cars. This year one sixth of undergraduates in Beijing have registered at driving school. The students, mostly from majors such as business management or imitational trade, will finish their driving courses within 20 days or so.

    Training costs have dropped to 4, 500 yuan for students, according to the Haidian Driving School in Beijing. The price is not really low, but students will accept it, seeing it as an investment (投资) in their future. Familiarity with the operation of computers and fluent English are the basic skills graduating students need to find a job. But a driver s permit has become another factor (因素).

    "In the job market, owning a driver's permit sometimes strengthens a graduating student's competitiveness for a good position," says Li Hua, an undergraduate at the China University of Political Science and law.

    Cars will become a necessary part of many people's lives in the coming years, and it is difficult to get a permit out of campus because of the pressures on working people's time. "Having a full-time job after graduation offers limited time to learn to drive. We senior students have plenty of spare time, plenty of oppurtunity to learn," says another undergraduate at the university.

    Wu Dong, an official at the driving school, said undergraduates were very able and serious, and could grasp in an hour what ordinary people took four hours to learn. In this driving school, middle-aged people, young women and college students are the main customers.

    From March 1, 2018, to get a driver's permit, a beginner is now required to have at least 86 hours' practice before the final road test.
