It seems that no one can live a happy life without friendship. While a great number of people expect others to be their friends, they don't give friendship back. That is why some friendships don't last long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.

    Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven't been honest, you may lose your friend's trust. Good friends always depend on one another to speak and act honestly.

    Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.

    Sooner or later everyone needs understanding and help with each other. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend's place so that you can understand the problem better.

    No two friendships are exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.

    A Japanese company, Next Technology, has created a robot dog that can tell you how bad your feet smell, by using a powerful sensor fixed in its nose. If you feet don't have a bad smell. Hana-chan will happily wag its tail, if it's exposed to feet that are mildly smelly, it'll start to bark, and if they give off an extremely bad smell, it'll just fall over like the smell caused it to faint(昏倒).

    Foot odor (脚臭) is a big deal in Japan, where it's a custom for people to take off their shoes whenever they enter someone's home. In fact, exposing others to bodily odors can be considered annoyance in Japan. Some of the most brilliant minds in the country's tech industry have been trying to solve this problem. Last year, Thanko started selling axmpit (腋窝) fans designed to keep people's armpits nice and dry Now, we have Hana-chan.

    The robot dog has a special sensor for a nose, and can tell you if your feet smell just by sniffing them for a few seconds. According to some media reports, Hana-chan can help solve the problem of extremely smelly feet by spraying them with air freshener, but it's unclear whether this feature comes built-in, or if you'll have to pay extra for it.

    According to researchers at NextTechnology, the idea for Hana-chan was inspired by a person who desperately wanted some way to know if his feet smelled. "He told us his daughter had said his feet were smelly, " NextTechnology's Kimika Tsuji said. “But he didn't want to know how bad the odor was because he would feel hurt. That's why we developed this cute robot. "

    You may be able to make Hana-chan faint with your smelly feet, but it can have the same effect on budget-conscious people. NextTechnology plans to start selling the feet-smelling robot dog for ￥100, 000 ($9, 280) next May.

    The Island Rule is one of the best explanations scientists could give to the observable phenomenon that animals and humans have evolved (演变) depending on the resources available in their habitat (栖息地). Through time, scientists have noticed through fossil (化石) records that some large animals from mainland habitats have dwarf (矮小的) versions in bland habitats.

    A report from BBC described the existence of what scientists call “hobbit island” off a small island somewhere in Indonesia. It was given such a name because fossil records of tiny, humanlike creatures have been found in the region. What they called as “hobbits” or “Homo Floresiensis”, are only as tall as one meter and arc small versions of early human species with tinier brains.

    Though scientists cannot perfectly trace the origin of the “Homo Floriensis”, they believe that they arc human relatives, but it is the “island life” that has caused them to evolve as they have. Scientists have noticed through fossil records and existing organisms (有机体) today that it seems if large animals grow small in islands while small animals grow large in larger islands.

In theory, animal and human bodies have adjusted to the available food and fresh water in their habitats. Since there is no opportunity for them to leave their island, they might as well adapt.

    New York Magazine explained that islands usually have fewer predators (捕食者) than mainland ecosystems. However, it is the lack of resources that cause the death of many animals. As a means of natural adaptation, the bodies of these animals have evolved smaller than their ancestors, making their bodies require fewer resources.

    A report from Web Ecoist listed down a few examples of animals that have shrunk significantly compared with their ancestors. Some of these include the Bali tiger as small as leopards (豹).

    Generations of children grew up reading comic(漫画) books secretly, hiding out from parents and teachers who saw them as a waste of time and a risk to young minds. Comics are now gaining a new respectability at school. That is thanks to an increasingly popular and creative programme, often aimed at struggling readers, that encourages children to plot, write and draw comic books, in many cases using themes from their own lives.

    The Comic Book Project was started in 2001 by Michael Bitz at an elementary school in Queens. Since its creation, the programme, which is mainly conducted after school, has spread to more than 850 schools across the country. It has gotten a big push from the craze(狂热) among adolescents for comic book clubs and for Manga, a widly popular variety of comic originating in Japan.

    The point is not to drop a comic book on a child's desk and say “read this”. Rather, the workshops give groups of students the opportunity to collaborate(合著) on often complex stories and charac-ters that they then revise, publish and share with others in their communities.

    Teachers are finding it easier to teach writing, grammar and punctuation with material that students are fully invested in(投入). And it turns out that comic books have other built-in advantages. The pairing of visual and written plotlines that they rely on appear to be especially helpful to struggling readers. No one is suggesting that comic books should substitute for traditional books or for standard reading and composition lessons. Teachers who would once have dismissed comics out of hand are learning to exploit(利用) a style that clearly has a powerful hold on young minds. They are using what works.

    People are always looking for lost cities and occasionally one is found: Borobudur in Indonesia, for example. But perhaps some of the places people look for never existed — or did they? Here are just a few famous mythical (传说中的) cities.

    El Dorado

    El Dorado is a story that began in 1537, when Spanish explorers found the Muisca people in the mountains of what is now Colombia. They heard the story of a man who covered himself with gold and dived into a lake. Then people began to talk of El Dorado — 'the golden man'. Soon people started to think of El Dorado as a place, too — a city of gold and amazing riches. Nowadays, the name 'El Dorado' is still used to mean 'a place where you can get rich quickly'.

    Atlantis

    There was once an island in the middle of the Atlantic Ocean. It was the mythical island of Atlantis. The people of the island were very rich, thanks to the natural resources (资源) on their island. For hundreds of years, they lived simple lives. But slowly they began to change. They started to want power. So the gods decided to destroy Atlantis. Suddenly, the island and its people were swallowed (淹没) by the sea and were never seen again.

    Shambhala

    In Tibetan Buddhist tradition, Shambhala is a mystical (神秘的) country that is hidden somewhere behind the Himalayas. Shambhala is a word from an old language that means 'place of peace' or 'place of happiness'. It is said that there is no war in Shambhala, and in the future, when the world is full of war, a huge army will come out of Shambhala, destroy the world's bad rulers, and start a new Golden Age. Some people say this will happen in 2424.
