For teenagers, it's great fun to explore new places and it feels like an adventure, even when you know you're not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.

    ◆Do the map reading if you're being driven somewhere. It'll be easier if you keep the map following the direction you are traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat.

    ◆Get a group of friends together and go exploring. You'll need a good map, a compass, a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies. Tell someone where you're going before you set out and let them know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

    ◆See if your school or a club organizes orienteering(越野识途比赛) activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B(and B to C, etc. ) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compass and gain some special skills. In some way, it's not only good fun, but also a great way to keep fit.

    A private sixth grade is set to start its lessons at 1.30 pm every day because the school's teacher thinks his students will study better after a morning lie-in (懒觉).

    Instead of rising early for a 9 am start, students at the ￡15,000-a-year Hampton Court House, in East Molesey, Surrey, will get to enjoy a lie-in and work from 1.30 pm until 7pm. Head teacher Guy Holloway says the move for all sixth grade students, set to begin from September, has been made according to research by scientists. He predicts (预测) that not only will his students aged 16 and upwards get great night's sleep, but their productivity (效率) will also be improved.

    The co-educational school will have the latest start time in the UK, and will be the only one to begin lessons in the afternoon.

    Experts say young people are programmed to get up later, and that rather than laziness it is simply a shift (转变) in their body clocks.

    There are 168 hours in a week and how productive they are depends on how they choose to use those hours,' said Mr Holloway. 'At Hampton Court House we don't think we have the answer for everybody; it's about what works in our school. We want to get them into a condition where they can get great sleep and study well.' He said students would also benefit from reduced journey times as they travel to and from school after rush hour (上下班高峰时间).

    Year 10 student Gabriel Purcell-Davis will be one of the first of 30 A-level students to start at the later time. 'I want to wake up in my bed, not in my maths lesson,' said the 15-year-old. Lessons for all other students at the school will still begin at 9 am as usual.

    Once upon a time, a daughter complained to her father that her life was unhappy and that she was tired of struggling all the time.

    Her father, a chef, took her to the kitchen. He filled three pots with water and placed each on a high fire. Once the three pots began to boil, he placed potatoes, eggs and coffee beans in them. After 20 minutes, he took them out, putting the potatoes and eggs in a bowl and the coffee in a cup. Turning to his daughter, he said, “Look closer, and touch the potatoes.” She did and noted that they were soft. He then asked her to take an egg and break it. After pulling off the shell, she observed the hard-boiled egg. Finally, he asked her to taste the coffee. Its good smell brought a smile to her face.

    “Father, what does this mean?” she asked. He then explained that the potatoes, the eggs and the coffee beans were in the same adversity (逆境)—the boiling water. However, each one reacted differently.

    The strong and hard potato became soft and weak in boiling water. The egg was fragile, with the thin outer shell protecting its liquid until it was put in the boiling water. Then the inside of the egg became hard. However, the coffee beans were unique. After they were exposed to the boiling water, they changed the water and created something new. “Which one do you want to be like?” he asked. “When adversity knocks on your door, how will you respond?”

    In life, challenges happen to us all, but the only thing that truly matters is what happens within us.

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel stressed to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset helps them to learn a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.

    The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centres are set up. In their study, the researchers examined groups of nine-month-old babies in New South Wales and Britain.

    And they came across astounding (令人吃惊的) results. It was found that infants had "social brains" and focused not just on their mothers but on social life in groups as well.

    "They communicate with more than one baby at once, and show jealousy and generousness," said Professor Bradley.

    He added, "They develop their own meanings through group interaction, they notice if a group member is behaving differently and they take on roles, such as leaders and followers."

    "A baby who has a depressed mother tends to be withdrawn (内向的), but put that same baby in a group of its peers (同龄人) and they behave and interact like any other baby."

    It was the first all-baby group study ever to be conducted. "Most studies of babies concentrate on the infant-mother relationship, assuming that is the single foundation for mental health, but babies are constantly involved with groups of people other than their mothers, fathers, siblings, grandparents and those taking care. Therefore, the mother-baby approach needs to be combined with a group approach," said Bradley.

    Phoebe Christison, a child-care worker at Camperdown Sunshine Bubs in Sydney's inner west, said she often noticed what appeared to be emotional attachments developed between toddlers.

    She said, "Joel (1) months and Isabella (2) months always like to hold hands when they sit in their high chairs and eat. And babies definitely show jealousy. They push and touch each other, and copy what the other is doing."
