When Luke went to university he thought he would be on a new journey in life and getting his own place. In the UK, it's common to fly the nest at a fairly young age. Many choose a flat-share; others make plans to get on the property ladder.

    But the current economic situation forced Luke back to his mum's house at the age of 27. And he's not alone: a quarter of young adults in the UK now live with their parents. The Office for National Statistics said more than 3.3 million adults between the ages of 20 and 34 were living with their parents in 2013.

    Lack of jobs and the high cost of renting accommodation made Luke change his plans. He's upset. "There's something very difficult about being an adult living in an environment where you're still a child," he says. "It limits me socially; sometimes I feel it limits me professionally."

    Indeed, many young people have no choice but to stay at "the hotel of Mum and Dad".

    Krissy had to return home after a year away and now lives in rather terrible conditions, sharing the family's three-bedroom house with her sisters. She says they end up getting on each other's nerves when it's time to use the bathroom in the morning.

    Of course, living with your parents is not unusual in some countries. Economic conditions, culture, or family traditions mean many young people stay at home until they get married. Even then, it can be too expensive to rent or buy a house and the married couples continue to live at one of their parents' homes.

    But some parents seem to enjoy having their kids back at home. Janice's daughters are part of what's being called "the boomerang generation". She says, "I get to share their lives with them, and I've got to know them all as adults. We have the sort of conversations that good friends do."

    So for some it's a win-win situation — spending time with your families, and saving money.

    The percentage of women working in technology has decreased since the 1990s.Women make up only a quarter of all jobs in computer and math professions.I think all girls should learn how to code（编码）.Here is why.

    If we want to be part of one of the fastest growing job markets out there,we need to jump on board!Over the last ten years the growth in STEM jobs has been three times faster than that in non-STEM fields.Women will never be able to keep up with men in the professional workplace if we don't join the fastest growing fields.

    Just like hundreds of years ago,people who could read and write controlled the future,and now those who are at home with technology will shape the world we live in.You can use coding in every aspect of your life,even if you don't enter a field that involves coding.You cant use coding to create your own website or to program games.You can animate your YouTube videos,or make graphic designs.Programming is now being used in every profession, including medicine and airplane design.

    You can have fun creating your own website,programming a robot to get the remote for you when you're lying on the couch,photoshop pictures to change the color scheme to something better than the Instagram filters,and so much more.Coding allows you to realize your wildest dream,and create anything you can imagine.Coding allows you to rule the world.

    It's not very hard to learn to code.You could learn to code on YouTube,in the Girls Who Code club;you could take a free course online on Code Academy;you could even just Google how to code.

You learned to read,you learned to drive-now learn to code.

    How did people in ancient China change their luck? Most of them would take the exam, Keju, which began during the Sui Dynasty and lasted for 1,300 years before it was ended in the Qing Dynasty.

    Keju, the early “gaokao”, played a very important role in choosing qualified persons to work for the king.

    The Keju exams were mainly based on classical literature(文学) and philo- sophy. Poetry was very important in earlier Keju exams, and later Keju focused more on writing.

    All candidates had to write an article explaining ideas from those books, which was called Eight Part Essay. Two sentences were required at the start of the article, about the main idea of the title, which was called “to clear the topic”. The exams also focused on more practical matters.  

    Most candidates in ancient China had to go a long way to the capital city for the exam. As transportation in ancient times was not developed, they usually went to the capital on foot, and some took several months to reach the capital.

    The exam was held once every three years and it was made up of four levels: the county examination, provincial examination, academy examination and palace examination. Candidates had to first pass one level in order to take part in the next level. Each examination would take from one to three days to finish, and they were locked in a small room and received cold meals.

    On the exam day, candidates had to first go through safety check. They had to let their hair loose so that it could be checked and their trouser legs, shoes and socks, even bottoms were also checked.

    Most people will answer a ringing phone. Usually you don't know who is phoning or how urgent their business is, so a ringing phone is difficult to ignore. In one experiment, a researcher wrote down the numbers of several public phones in stations and airports. Then he called the numbers. Someone nearly always answered. When he asked why, people usually said, "Because it rang."

    A few years ago in New Jersey, a man with a rifle killed 13 people. Armed police surrounded his house but he refused to come out. A reporter found out the phone number of the house and called.

    The man put down his rifle(步枪) and answered the phone. "What do you want?" he said, "I'm really busy right now."

    Imagine you're at work and the phone is ringing in someone else's office. Do you answer it or not?

    In one survey on telephone use, 51% of participants told researches that they did. We can't ignore the phone and for the reason, it forces its way into our lives. It interrupts what we are doing and on top of that, the caller is often someone we don't really want to talk to. However, in the survey, 58% said they never took the phone off the hook, and 67% didn't mind if someone called during a television programme. For 44% it wasn't a problem if someone rang during a meal, while only 28% were annoyed or upset.

    If someone phoned in the middle of the night, 40% told researchers that they got nervous or frightened, while around 30% got angry.

    Of course, when someone is really annoying, you can choose to hang up on him/her. This is in fact one of the rudest things you can do on the phone, but 79% said they were prepared to do it in some cases. Only 6% told researchers they never hung up on people.

Spending all day glued to your smartphone probably isn't doing you any favors. Too much phone use has been linked with a range of concems, including sleep issues, joint pain and even relationship problems. But if it's radiation you're worried about, experts say you don't have to ditch your phone. 

"There's no risk of anything hazardous or dangerous with radiation from cellphones, "said Gayle Woloschak, an associate dean and professor of radiology at the Northwesterm Univerity Feinberg School of Medicine. As with all cellphones, along with Wi-Fi networks, radio stations, remote controls and GPS, smartphones do send out radiation, said Emily Caffrey, an assistant professor of health physics at the University of Alabama at Birningham. They use invisible energy waves to transmit voices, texts, photos and emails to nearby cell towers, which can carry them to almost anywhere in the world. But nearly three decades of scientific research has not linked such exposures to medical issues like cancer, health authorities including the Food and Drug Administration say. Here's what we know. 

"Radiation"describes many types of energy, some of which do carry risks, explained Dr. Howard Fine, director of the Brain Tumor Center at NewYork —Presbyterian Weill Cornell Medical Center in New York City, "It is often sent out from radioactive substances", Atomic bombs, or, to a far lesser degree, X-ray machines, send out energy called ionizing radiation that in high enough or frequent enough amount can damage DNA and cause cancer, Dr. Fine said. 

But smartphone energy falls into a category called non-ionizing radiation, Dr. Caffrey said, which isn't powerful enough to cause this damage. "A lot of people think‘radiation is radiation, 'but it's not all the same, "Dr. Woloschak said. "There's no DNA damage seen from cellphone use. "

Most experts and health authorities like the F. D. A. and World Health Organization agree that there's no evidence that smartphone radiation causes health problems. Still, several studies over the years have made headlines for suggesting their links to brain diseases. Many of these studies have since been proved to be false, Dr. Fine said, including those focused on fifth-generation.
