    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable.

    Good luck!

    Eddie, Aged 20

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    I am not going to lie. The first day is kind of frightening. But you'll get used to it. Don't be afraid of anyone; upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    Most of us have been in this situation: You're on your way to your friend's house, then you suddenly ask yourself,"Did I remember to turn the lights off?” For those with "smart homes", however, this wouldn't be a problem.

Over the last few years,smart home technology has become more popular. Thanks to user-friendly products like intelligent lighting and heating controllers, people can control nearly every electrical item in their homes from anywhere in the world.

    While smart homes aren't new, companies like Philips, Amazon and Xiaomi have finally brought automation to everyday people with affordable products like artificial intelligence(AI) speakers and sensors.

    “The obvious message is that you can stop wasting energy,” Tom Kerber, director of research for U. S -based digital company Parks Associates, told The Guardian.

    And the technology also has more meaningful uses. In Norway, for example, one company is using smart tech to make life easier for its elderly customers. Abilia's system allows carers to check up on patients through a tablet on a wall inside their home. The device sends patients reminders about tasks, such as when they need to take medication(冥想). It can even tell carers if there's any unusual activity in the home that could be life-threatening.

    “This kind of system allows people to take care of themselves, which is the most important thing,” Abilia's vice president, Oystein Johnsen, told the BBC. "It also saves the government money. In Norway, it costs 1 million kroner(about 0. 8 million yuan )per year to have someone in a care home. This system costs 15,000 kroner a year.”

    So, for those who have already "gone smart", will it ever be possible to go back to do things in the old-fashioned way? "I think it would be difficult. When we go to a friend's house or on vacation we find ourselves expecting the house to do things for us that we should do, "Poulson, 35, a senior program manager from Seattle.,U. S.,explained.

    Tattoos (纹身) are becoming more and more common. But they are not a new thing. Scientists have found some frozen bodies from around 3,000 BC and their skin shows the marks of tattoos. For example, Otzi, the Iceman (the oldest body ever found), was discovered in the mountains of Austria. He had many different lines and crosses tattooed on his back and his knees.

    The most common places to get tattoos are the tops of the arms for men and the bottoms of the backs for women. Any mark can be used but there are some common ideas. Some people like to get animals, like dragons, birds and tigers. Other people like to get something written in a foreign language, so Chinese and Japanese words are common in America and the UK. If you can't read the language, make sure you get someone to check what they represent because the tattoo artist could write anything and you would never know.

    It is a big decision to get a tattoo because they are very difficult to remove. It is possible with expensive laser surgery (激光手术) but this is very painful and amazingly expensive and the skin will never be perfect afterwards. You want to do a test, to see how you look with a tattoo, you can get a temporary tattoo which disappears after about a month. This kind is very popular in India, where people often have them for festivals.

    In some countries, such as Japan and Korea, tattoos are still connected with law-breaking activities and it isn't normal to see a tattoo in public. In many places of Europe and America, most people don't care very much whether you have a tattoo or not, though there are some types of job where they don't like tattoos. But some Presidents of the USA have had them.

    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 (辐射) 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.”

That night, when Aksionov was lying on his bed and just beginning to sleep, someone came quietly and sat down on his bed. He peered(看) through the darkness and recognized Makar.

"What more do you want of me?" asked Aksionov. "Why have you come here?"

Makar Semyonovich was silent. So Aksionov sat up and said, "What do you want? Go away, or I will call the guard!"

Makar Semyonovich bent close over Aksionov, and whispered, "Ivan Dmitrich forgive me!"

"What for?" asked Aksionov.

"It was I who killed the merchant and hid the knife among your things. I meant to kill you, too, but I heard a noise outside, so I hid the knife in your bag and escaped out of the window."

Aksionov was silent, and didn't know what to say. Makar Semyonovich slid off the bed-shelf and knelt upon the ground. "Ivan Dmitrich" he said, "forgive me! I will confess that it was I who killed the merchant, and you will be released and can go to your home."

"It is easy for you to talk," said Aksionov "but I have suffered for you these twenty-six years. Where could I go now?... My wife is dead, and my children have forgotten me. I have nowhere to go..."

Makar Semyonovich did not rise, but beat his head on the floor. "Ivan Dmitrich, forgive me!" he cried. "When they flogged(鞭打) me with the knot, it was not so hard to bear as it is to see you now... yet you had pity on me and did not tell. Forgive me, devil that I am!" And he began to sob.

When Aksionov heard him sobbing, he too, began to weep. "I will forgive you!" he said. "Maybe I am a hundred times worse than you." And at these words his heart grew light, and the longing for home left him. He no longer had any desire to leave the prison, but only hoped for his last hour to come.

In spite of what Aksionov had said, Makar Semyonovich confessed his guilt. But when the order for his release came, Aksionov was already dead.
