Lights out, phones on. Many teenagers reach for their smartphones or tablets at bedtime, but it may be a good idea to switch off before you hit the pillow.

    According to a study by researchers at Murdoch and Griffith Universities in Australia, using mobile devices late at night could harm teenagers' sleep and lead to an increased risk of mental health problems.

    The study was carried out on more than 1,000 Australian high school students aged between 13 and 16. It lasted four years as student participants moved from Year 8 to Year 11.

    During the study, students were asked what time of the night they received or sent text messages and phone calls, and how well they slept.

    The results are impressive. When the study started in Year 8, more than 85 percent of the students had a mobile pone and around one-third of these students never used phones after lights out. In contrast, 93 percent of Year 11 students had a mobile phone and only 22 percent of then had no late night mobile use when the study concluded four years later.

    As the levels of mobile phone use increased, there was a growth in poor sleep behavior among the students. Meanwhile, mental health problems also increased. Students in Year 8 who were more likely to use phones at night were found to have higher levels of depression (抑郁) and lower self-esteem (自尊心) one year later.

    Lynette Vernon, lead author of the study, explained that phones affect our sleep patterns because of the unnatural blue light they produce. This light could affect the level of hormones (荷尔蒙) in the body, disrupting (打乱) its balance.

     “The more you sit in bed and watch TV, play with your tablet, and play with your phone at three o'clock in the morning, the more these things affect the slow waves of your sleep pattern and give your poor quality sleep,” Mark Levi, a Sydney-based sleep doctor said.

    Based on the findings, the researchers suggested parents should focus on guiding their children's use of mobile devices.

    According to Vernon, the solution is not simply to ban teenagers from using their devices, but teach them better ways of using them

     “Back when they're aged 7 to 10, you have to be a role model. If you put your phone away at night and it doesn't go into your bedroom, it becomes normalizedin the household and you have a much easier job,” he told The Guardian.

    Your next car could have two seats, three wheels — two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in the center with the passenger directly behind.

    The starting price for the car is just $6,800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motors. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating U.S. manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. “Whatever matters to you, this can move the needle on it,” he said.

    Already, more than 27,000 people have reserved (预订) one. Paul hopes to make 250,000 cars a year by 2016. So far, reservation holders are those who will use the Elio as a second or third car for work. Finally, though, he believes the car will interest high school and college students as well as used-car drivers who want something newer and more reliable.

    Does meeting new people make you nervous(紧张的)? If so, you're not alone. {#blank#}1{#/blank#}Here are some simple choices.

    Look your best

    Obviously the way that you look like decides people's impression (印象) of you. But you don't need to look like a model to make a good impression. You just need to take care of yourself. Make sure your clothes are clean, tidy and right for the situation. It is said that blue or black are best for job interviews. {#blank#}2{#/blank#} They change how people see you.

    Stand tall

    {#blank#}3{#/blank#} Standing up straight makes you look and feel confident. When you get close to someone, smile to show you're friendly and interested. Then greet them with a firm handshake.

    Speak up

    Speak loudly and clearly enough that people can hear you. If you don't know what to say, ask questions. Most people enjoy talking about themselves. Listening is just as important as talking. When people are talking, pay attention to what they're saying rather than planning what you'll say next. {#blank#}4{#/blank#} .

    {#blank#}5{#/blank#}

    Most importantly, show people you care. Your concern for them will be clear if you smile and listen carefully. Respect other people's time, too. Don't keep them waiting because you arrive late or keep using your cellphone instead of talking to them. Everyone you meet, whether they're a businessperson, a reporter or a bus driver, is important.

A. Don't forget little things like brushing your teeth and washing your hair.

B. Never be late

C. But meeting new people isn't as hard as you might think.

D. Respect people

E. You are stubborn, and others' opinions can't change who you are.

F. The way you stand, sit and move tells others a lot about you.

G. If you're not sure what they mean, ask!

    Every time a new year is coming, people set out to better themselves. They promise they will lose weight, find a new job, or maybe even take that vacation they've always talked about. But why do we make these promises to ourselves, and where did this tradition come from? Why does this tradition live on when so many people fail to keep the resolutions(决定) they made? Well, we can start by blaming the ancient Babylonians.

    Around 4, 000 years ago in Babylon, the earliest recorded celebration honoring the coming of a new year was held. Calendars weren't as they are today, so the Babylonians did it in late March during the first new moon after the Spring Equinox(春分). The festivities were meant for the rebirth of the sun god, but the Babylonians made promises in order to please their gods. They felt this would help them start the new year off well.

    Resolutions continued on with the Romans. When the early Roman calendar no longer synced(同步) up with the sun, Julius Caesar decided to make a change. He consulted with the best astronomers and mathematicians of the time and introduced the Julian calendar, which more closely represents the modern calendar we use today. Caesar declared January 1 the first day of the year to honor the god of new beginnings, Janus. The Romans celebrated the New Year by offering sacrifices to Janus.

To this day, the traditions of the ancient Babylonians and Romans continue around the world. So much that Google launched a Resolution Map in 2013 where people could add resolutions and see others adding theirs in real time. However, no matter how many people participated in Google's project, the numbers are bleak when it comes to the number of people who maintain their resolutions—-only eight percent of people are successful in sticking them out.

    During the past Spring Festival, many children may have received red packets from their families. But Xing Pu, a 40-year-old economist, is asking the government to give red packets to every Chinese citizen.

    Xing suggested the government give out 1,000 yuan to each Chinese since the government income has increased rapidly in recent years. He said his suggestion would allow everyone to directly enjoy the fruits of the country's economic success, help the lower-income groups deal with rising prices and increase consumption around the country.

    Recent years have seen the government carry out a series of pro-poor (扶贫)and prorural (惠农)policies, including increasing spending on public health-care and cutting down the agricultural tax. But the lower-income group still needs more help.

    Xing said he has borrowed many ideas from practices in countries like the United States and Singapore. Earlier this year, the governments of the two nations offered cash handouts (救济)to their citizens. As for in China, "We can even encourage the rich to donate their 1,000 yuan red packet to the poor" said Xing.

    Although Xing's suggestion has gained wide support among ordinary Chinese on the Internet, many other economists criticized it as unpractical. "To better use the increase of money, handing out money is not a solution that holds good for all time. It could be better to improve the public service or cut the price of energy use in daily life," said Qiao Xinshcng, an economic professor.
