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.

    A heated debate is currently going on in our town.Should we allow the cinema to be constructed in the Havenswood Shopping Center? There is just one large lot left to build on,and the theater would use up all of that space.Some people are excited at the idea of finally having our own movie theater.Others would rather travel ten miles to the nearest theater to keep our quiet town the way it is.They say it is enough to have Marvin's Movie Video Rentals.After all,Marvin's store keeps thousands of the latest videos.

    There are certainly benefits to renting videos.For one thing,you can plan your own schedule when it is convenient for you.You can relax on your sofa,and take a break whenever you need one.You can also talk to others without bothering any strangers seated nearby.In additional,it is a less expensive way to view a movie compared to going to a theater.

    On the other hand,seeing a movie in a theater is an experience all its own.First,you can see the movie on wide screen as the filmmaker intended.To be viewed on a television screen,a film must be changed in some way to make it smaller.One is the “pan-and-scan” method,which involves removing some of the details in the picture.The other way,called “letterboxing”,keeps the image the way it is on the big screen,with one annoying exception; because the big-screen version is wide,the same picture on a television screen must be long and narrow.

    Another problem is sound.The sound from a television cannot compare to the sound system in a theater.Your experience of a movie improves when you can clearly hear all of the sounds.Furthermore,at home,viewing companions often talk during a movie,which makes you miss out on what's happening in the film.

    Besides,having a movie theater will not mean that you can't still go to Marvin's! You will just have a choice that you didn't have before.Isn't it time for Havenswood residents to enjoy a little progress?

The First Hello

    The man from the telephone department got off the bus, and made his way to the tea stall, wiping the sweat off his head, face, then slipping his handkerchief under his shirt to wipe his neck and back. It was a year ago that the phone line had been installed, six months later men from the public works department had come to put up the phone booth—a neat box-like structure, with a glass window, and wooden ledges, yellow in colour. And days after that, a painter had taken an entire day to colour in broad, black brushstrokes, the words: STD Booth, local and STD allowed.

    No one could tell that the last word had been misspelled. Besides, he had taken the entire day. After he had a cup of tea, he left, waving cheerfully. And now months later, someone else was here again.

    Everyone watched the man as he sat on the bench. No one said a word, and soon the sound of him slurping his tea filled the hot afternoon. A few leaves fell, heavy in the heat, and sometimes a car passed, on its way to the main city farther away.

    When the man had finished, he tried to pay but the tea shop owner who sat behind his steaming kettle and the washed upturned cups, waved him away.

    “You are our guest here.”

    So the man took his handkerchief out again and wiped his face.

    They crowded around him as he shut himself up in the phone booth. When the children pressed their nose against the glass, he shooed them away, as he took out a shiny black soon changed to an excited yell as they saw him dial a number, pressing a finger into the ringed dialer of the phone and letting it go all the way in a half-circle. A while later, they hear him say into the mouthpiece, “Hello.”

    “Hello,”the children around the booth took up the cry, the teashop owner broke into a smile and the men waiting for a bus smiled and said hello to each other. The sadhu(印度的僧人)who sat under the banyan tree nodded wisely. As the sound carried, more hellos were heard. The women winnowing grain giggled as they tried the word tentatively, the shepherds feeding their flocks called out to their sheep, laughing as they used the word.

    “It's a big occasion, ”said the headman, in an awed(敬畏的) voice.

    “It is.” agreed those around him. The telephone man emerged and handed over a small chit of paper to the headman. “This is the telephone number.”

    The headman looked at it respectfully as if it were a mantra(符咒). The others around him read out the numbers slowly, digit-by-digit.

    The telephone man was now too tired to notice the cheering around him. He knew he had to wait long before the bus to take him back arrived. As he sipped his second cup of tea, he remembered something else.

    “Oh, you can't start using the phone now. The minister will come next month and inaugurate it. ”

    No one said a word. No one was surprise. They had waited so long; a month more did not really matter.

    Plan on traveling around the USA this summer? If you need help in arranging the trip, or want ideas about where to go and what to do, there are a number of outstanding websites that can make your American dream come true.

    When introducing American universities, some of the first institutions to mention are the Ivy League schools. Originally, the Ivy League was an athletic conference made up of 8 private institutes of higher learning in northeastern United States. However, as time went on, these schools also became known for their excellence in academics besides athletics. Included in the Ivy League schools are Brown University, Columbia University, Cornell University, Dartmouth College, Princeton University, University of Pennsylvania, Yale University, and Harvard University. These 8 schools have been recognized as some of the best colleges and universities in the United States.

    Harvard University is a private institution located in Cambridge, Massachusetts. The university includes a number of graduate and professional schools, as well as a college for undergraduates. In 2012, Harvard ranked number one in US News' ranking of national universities again. Founded in 1636, Harvard is the oldest institute of higher education in the United States. It can be said that first there was Harvard, then the United States of America. Also, Harvard's library contains the oldest collection of books in the United States as well as the largest private collection in the world. Harvard has also been described by Forbes Magazine as one of the "billionaire universities" as of their recent list of 469 billionaires, 50 received a degree from Harvard.

    Harvard College (the institute for undergraduate students) is one of the most famous schools in the United States. It offers over 40 undergraduate fields of study, including astrophysics(天体物理学), mathematics, neurobiology(神经生物学), etc. And the financial aid program there is amazing. Even though the tuition is about $ 37,576, and there are other expenses throughout the year, about 70% of undergraduate students received financial aid. Out of those students, over 90% of them had their full need met. And the policies for international students are the same for U.S. citizens.

    Harvard College is very selective, as it only admits about 6% of their applicants. For admission into Harvard College, it is required that students take the SAT or the ACT, as well as SAT Subject Tests. Harvard will also look at other factors during admission such as your application essay, high school transcript, work experience, GPA (Grade Point Average), your interview, recommendations, and most importantly, your character and personal qualities.

    Eating is best when it's a social activity. Think of the meal a family enjoys in the evening when everyone's together after work or school, or the big get-togethers over food at Spring Festival. But now, in the age of the Internet and social media, anyone with an Internet connection can enjoy a social eating event.

    Mukbang-a South Korean phrase meaning “eating broadcast”-is an unusual food fanaticism that's sweeping the country. This is a meal where only one person gets to eat, while many viewers watch live shows of hosts eating large quantities of food. They leave comments on the dishes the host is taking, and the host responds to them live.

    So why have people taken to this unusual new food trend(趋势)? Jeff Yang, an Asian-American cultural critic, thinks that it's down to “the loneliness of unmarried or uncoupled South Koreans”. He believes that eating on your own can be hard in a country like South Korea, where social eating is such a long tradition. However, Mukbang gives people the feeling that they are part of something larger, it seems.

    Millions of people have trouble with food. Either they eat too much of it, or too little. Some say that the popularity of Mukbang helps people with these disorders. Those who always eat too much and put on weight can watch Mukbang live shows to satisfy their appetite (胃口). And those who don't eat enough can build their appetite by watching delicious food being eaten.

    Even though Mukbang is a South Korean phenomenon, it's also taken off in the US. But unlike South Koreans who sit down to enjoy noodles and kimchi (泡菜), Americans enjoy their own native dishes. This means that viewers of US Mukbang live shows will see locals stuffing themselves with hamburgers, fries and ice cream.
