High school plays a major role in shaping up your future and your whole development. Extracurricular (课外的) activities along with the studies can be very helpful. Make yourself take part in various activities and at the same time try to stand out in your studies. When you move out to college these efforts that you put in may count for a lot.

    High school is not just about books or classes. Schools always provide opportunities for students to socialize (社交). There are various group tasks designed which allow the students to learn to work together.

    High school is the right time for you to discover yourself and bring out some of your hidden talents. In your lessons, you may find that you are better at English than you were earlier or have grown an interest for Math. High school also provides many other opportunities for students to take part in. These help develop leadership skills and management skills at an early age, which in turn is a way of preparing students to manage and plan their careers (事业) better.

    Balancing all activities is an experience in time management. If you have taken up a part-time job along with your high school you would have to arrange your time for studies, and extracurricular activities. Such management can go a long way in teaching you to manage things better when you take up a job. Moreover, they help build your character. You would be better prepared for additional stress that you may feel sometimes.

    When at high school you should pick up your classes wisely. Depending upon what you like and your career plan you should choose suitable classes. Doing something that you hardly like may get you very low grades as well as lose valuable time. Take up interesting and challenging classes that would allow you to put in those extra efforts.

    The American state of Colorado is considering a ban on smartphones for children younger than 13.

    A Denver-based doctor - and father - is leading the effort. Tim Farnum is the founder of a group called ‘Parents Against Underage Smartphones.' His proposal would ban sales of smartphones to children under the age of 13. It would also ban sales to anyone who wishes to buy such a device for anyone younger than 13. The measure would also require sellers of smartphones to provide proof to the state government that they have asked buyers if the phone is for anyone under 13.

    The measure now needs about 300,000 signatures in order to appear on Colorado's statewide ballot (投票权)next year. If it makes the ballot and is approved by voters, Colorado would become the first state to have such a ban.

    Tim Farnum said he decided to push for the measure after watching his own children struggle with the mental effects of always having a smartphone around. "They would get the phones and lock themselves in the room and change who they were," he told The Coloradoan newspaper.

    State Senator John Kefalas, a Democrat, said he understands the reasoning behind the proposed law. However, he told The Coloradoan that a child's smartphone usage is a "family matter" and not something the government should decide. "Ultimately, this comes down to parenting,” he said, “making sure their kids are not putting themselves at risk.”

    Last year, the AAP (the American Academy of Pediatrics) released guidelines for media use by children. The group advised parents to limit time spent watching videos to no more than one hour a day of high-quality programming until age 6. After that, it said, parents should set reasonable time limits for their children and make sure electronic devices do not take time away from sleep or exercise.

    Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word “green” means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 15th century, a greenhorn was a young cow or an ox whose horns(角)had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18th century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20th century. A person with a green thumb can make plants grow quickly and well.

    Green is also the color used to describe the powerful feeling , jealousy(嫉妒). The green-eyed monster （怪物）is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants. For example, a young man may suffer from the green-eyed monster if you get a pay rise and he does not.

    In most places in the world, a green light means to move ahead. In everyday speech, a green light means agree to continue with a project.

When we meet someone for the first time, we usually get a vague sense of what kind of person they are by the way they shake hands, talk, or walk. In the age of social networking, however, first impressions are sometimes made even before we actually meet someone in person—that is, by looking at their profile photo.

    According to a recent study, these social images say a lot about our personality. In the study, presented in a paper at the International AAAI Conference on Web and Social Media, a group of researchers from the University of Pennsylvania in the US used software to analyze the profile pictures of 66,000 users of US social platform Twitter and 3,200 of their tweets. At the same time, about 434 participants were asked to complete a survey about their personality type. The researchers wanted to find out if there was a connection between personality traits—like openness, extroversion, and neuroticism(神经质)—and a person's profile picture.

    According to the results, open people are more likely to pose in an unusual way and use objects such as glasses or a guitar in their profile photo because they enjoy new and exciting experiences. Meanwhile, neurotic people often hold back their negative emotions. They try to avoid showing their face；Instead, they use an image of something like a pet, a car or a building.

    Apart from the objects in profile pictures, the colors used in them also give us some hints about the photo's owner. For example, extraverts were found to have the most colorful profile images, as they want to emphasize their personality and show themselves off, the researchers wrote.

    Although social media photos "usually represent an extension of one's self, they also allow a user to shape his or her own personality and idealized view," according to the researchers. So, when choosing a profile photo, maybe we should ask ourselves first what kind of image we'd like to convey. After all, first impressions always last.

Traveling Tips

    No Smoking

    Federal and State Government Regulations do not allow you to smoke on board express coaches within Australia.

    Luggage Allowance

    As a fare paying customer you are entitled to take 2 pieces of personal luggage. Each must not exceed 75 cm in length, or weigh more than 20kg.

    Excess luggage will be carried at the company's excess luggage rate and depending on space availability may be required to be carried on another coach.

    Luggage Tips

    1) Keep your valuables with you. Money, jewellery, valuable documents, credit cards, keys, medications should be retained by you and not on the coach at meal or transport stops.

    2) Use sturdy, lockable luggage. Do not use plastic bags as these may split during the transit.

    3) Make sure you identify your luggage with a name tag.

    4) Backpacks—stow all items and do not leave mugs, shoes, towels hanging off your backpack as these can get caught in other luggage and cause damage.

    Departure Times

    The time shown on your ticket is the coach departure time. If you are boarding halfway and not at a travel centre or terminal you should be at the pick up point 15 minutes ahead of this time, so you can be comfortably on board by the time the coach is due to leave. If you are boarding at a travel centre or terminal, please arrive at least 20 minutes prior to the published departure time and remember to allow extra time at peak travel times.

    Finland is the happiest place on Earth, according to the 2018 World Happiness Report of 156 nations.

    The report, released Wednesday by the United Nations'Sustainable Development Solutions Network, ranks the countries of the world based on six different categories of well-being: income, freedom, trust, life expectancy, generosity and social support. This year's report also pays special attention to the happiness of each country's immigrants.

    The U.S. dropped four spots from 2017 and landed in 18th place, and last year's winner, Norway, came in second place — followed by Denmark, Iceland and Switzerland.

    “The top five countries all have almost equally high values for the six factors found to support happiness, and four of these countries—Denmark, Switzerland, Norway and now Finland — have been in first place in the six World Happiness Report rankings since the first report" in 2012, "co-editor John Helliwell told CNN. “In a division with such excellent teams, changes in the top spot are to be expected."

    Rounding out the top 10 happiest countries was Canada in sixth place, then New Zealand, Sweden and Australia. The order of the top 10 nations changed from the 2017 list but the countries did not, according to the report. They were also 10 of the 11 top spots in the immigrant happiness category (including Mexico — 24th overall, but 10th in immigration).

    "The most striking finding of the report is the remarkable consistency between the happiness of immigrants and the locally born," Helliwell said in a statement. "Although immigrants come from countries with very different levels of happiness, their reported life evaluations resemble those of other residents in their new countries. Those who move to happier countries gain, while those who move to less happy countries lose."

    Other major world powers placed in significantly low spots on the list. Germany came in 15th, the UK was 19th — followed by Japan in 54th place, Russia in 59th and China in 86th.

    The report, based on surveys completed by citizen volunteers, came just under a week before World Happiness Day on March 20, when the UN declared to recognize "the relevance of happiness and well-being as universal goals and aspirations in the lives of human beings around the world and the importance of their recognition in public policy objectives"
