Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we are often able to know where most words come from.

    Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburger. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Germans did not understand the question and answered. “We came from Hamburger.” One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburger ate. Then he put each between two pieces of bread and started selling them. Such bread came to be called “ hamburgers”.Today “hamburgers” are sold in many countries around the world.

    Whether this story is true or not, it is certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason, for most English words, can be found in any large English dictionary.

    Australia is a big country, but it is easy to get around. The untouched beaches that go for miles and deserts that touch the horizon(地平线) are just there, waiting to be reached and explored. You can explore the big country in different ways.

Air

    Flying is the best way to cover large distances in a short time. You can spend more time on the Australia's landscapes(陆地风光) and relaxing lifestyle. Moreover, competition among airlines makes great flying fees available for you.

Drive

    Australia has a big network of well-kept roads and some of the most beautiful touring routes in the world. You have no trouble finding car rental companies at major airports, central city and suburbs(怒火).

Bus

    Bus travel in Australia is comfortable, easy and cheap. Buses generally have air conditioning, reading lights, adjustable(可凋) seats and videos. Services are good for everyone, frequent.

Rail

    Train travel is the cheapest and gives you an insight into Australia's size, all from the comfort of your carriage. Scheduled services are a great way to get quickly between our cities and regional centers.

Ferry(轮渡)

    The Spirit of Tasmania runs a passenger and vehicle ferry service between Melbourne and Tasmania nightly. Extra services are running during summer rush hours. Sea-link ferries connect South Australia and Kangaroo Island several times a day. Ferries connect suburbs in our capital cities.

    Besides all of above, you can also experience some of the longest tracks and trails in the world in central Australia-impressive journeys of a thousand kilometers or more that can take several weeks to complete.

    When we think about happiness, we usually think of something surprising and unexpected, a top great delight.

    For a child, happiness has a magic quality. I remember playing police and robbers in the woods, getting a speaking part in the school play. Of course, kids also experience lows, but their delight at tops of pleasure is easily seen, such as winning a race or getting a new bike.

    For teenagers, or people under 20, the idea of happiness changes. Suddenly it's conditional on such things as excitement, love, and popularity. I can still feel the pain of not being invited to a party that almost everyone else was going to. I also recall the great happiness of being invited at another event to dance with a very handsome young man.

    In adulthood the things that bring great joy — birth, love, marriage — also bring responsibility and the risk of loss. Love may not last; loved ones die. For adults, happiness is complex.

    My dictionary explains “happy” as “lucky” or “ fortunate”, but I think a better explanation of happiness is “ the ability to enjoy something”. The more we can enjoy what we have, the happier we are. It's easy for us not to notice the pleasure we get from loving and being loved, the company of friends, the freedom to love where we please, and even good health. Nowadays, with so many choices and much pleasure, we have turned happiness into one more thing we have. We think we own the right to have it, which makes us extremely unhappy. So we try hard to get it and consider it to be the same as wealth and success, without noticing that the people who have those things aren't necessarily happier.

    While happiness may be more complex for us, the answer is the same as ever. Happiness isn't about what happens to us. It's the ability to find a positive for every negative, and view a difficulty as a challenge. Don't be sad for what we don't have, but enjoy what we do possess.

    Lemurs are cute animals that live on the island of Madagascar, the fourth-largest island in the world. Lemurs have big eyes, long noses, and long tails(except for the Indri) and live high in the trees of Madagascan forests. Lemurs are quite intelligent. They are the cousins of monkeys and look quite similar. They also swing through the trees and live in family groups.

    There are different species of lemurs. Some lemurs (the Indri) sing like a whale, and some (the Sifaka) walk like a ballet dancer. Some lemurs are very small, like the Pygmy Mouse Lemur which weighs only 25-30 grams. Others, like the Indri, can weigh up to ten kilograms. Some lemurs are nocturnal, being awake at night and sleeping during the day, and some are not nocturnal but diurnal. Generally, the smaller lemurs are nocturnal, while the bigger ones are diurnal. All the species are unique to Madagascar.

    However, all of the lemurs are endangered species. Many species have already disappeared in the last few centuries. There are not many of lemurs left. People in Madagascar have been destroying the forests where lemurs live. Local people also hunt lemurs for food. Some of the local people see lemurs as bringers of bad luck, so they kill lemurs.

    At the moment, there are about 85 lemur species left. But many people fear that the number of species will fall quickly. Soon there may be no lemurs left if we do not make serious efforts to protect them.

Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out (分配) energy reserves during the night so that the plant can keep growing, yet not risk burning off all its stored energy.

While the sun shines, plants perform photosynthesis (光合作用). In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch (淀粉). At night, the plants burn this stored starch to fuel continued growth.

"The calculations are precise so that plants prevent starvation but also make the most efficient use of their food," said study co-author Alison Smith. "If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted. "

The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them.

During one of the exams, they shut off the lights early on them that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day means they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm.

Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth.

The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average.

The results of the study were published in e Life.

Education in 2080 is distinctive from education in the 2020s. Until about 2035, the main function of education systems was to supply the economy with the next generation of workers. In 2080, the purpose of education is the well-being of society and all its members. To make this a bit more tangible(可感知的;有形的) for you, I would like to give an example of what a child's education looks like in 2080. Her name is Shemsy. Shemsy is 13, and she is confident and loves learning. 

Shemsy does not go to school in the morning because schools as you know them no longer exist. The institution was abolished as it was widely thought of as more like a prison or a factory than a creative learning environment. Schools have been replaced with "Learning Hubs" that are not restricted to certain ages. They are where intergenerational learning happens, in line with the belief that learning is a lifelong pursuit. 

Every year, Shemsy designs her learning journey for the year with a highly attentive "teacher-citizen". Shemsy is actively engaged in designing her education and has to propose projects she would like to be involved in to contribute to and serve her community. She also spends lots of time playing as the role of play in learning has finally been recognized as essential and core to our humanity. Shemsy works a lot collaboratively. Access to education is universal, and higher education institutions no longer differentiate themselves by how many people they reject yearly. Variability between students is expected and leveraged （利用） as young people teach one another and use their differences as a source of strength. Shemsy naturally explores what she is curious about at a pace she sets. She still has some classes to take that are mandatory for children globally: Being Human and the History of Humanity. 

We invite you to think about your vision for education in the year 2080, what does it look like, who does it serve, and how does it transform our societies?
