How could you be "just ahousewife" when the basic social unit of society depends on you and yourservice? A housewife works for the longest hour, supporting your husband, childstudies, caring for eld-ers, managing finances, paying bills, grocery shopping,cooking according to individual taste, cleaning, etc. A housewife could beanyone: daughter, wife, mother, teacher, financial advisor, fashion designerand nurse, gardener, driver, cook, and so on. Don't think you are not being paid for it.  You get the re-ward that no money canoffer-the love and affection of your family, their trust in you, ahappy home and your own satisfaction.

    It is you who choose to be in thisoccupation, willingly or for any other reason. After a busy day, all wait to return to the comfortable home set by you.They know you will be there to absorb all their stress and tiredness and relaxthem. Would the life have been the same had you been working outside to earnsome money? Would you along with your family have been able to buy all thecontent in life that you are enjoying now with that money?

    Respect yourself for what you are. Introduce yourself to the world with the same dignity. The world understandsthe importance of your job; it's time to make them accept it. Introduceyourself with pride and with twinkle in your eyes "I am a housewife".Kick that "just" out.

    About three decades ago, China was known as the "Bicycle Kingdom". But later on, bikes were replaced by their fuel-powered competitors.

    But recent months have seen a recovery of the humble bike across China, with an increasing number of people choosing cycling instead of driving to schools, to workplaces or to do sightseeing. The introduction of bike-sharing schemes, pioneered by start-ups like Ofo and Mobike, has brought the trend to a new level.

    People can unlock the shared bikes by simply using their smartphone. The bikes are equipped with GPS and can be left anywhere in public for the next user. They're popular among many Chinese people as they provide an effective solution to the "last mile" problem, which refers to the final leg of a person's journey.

    " In places where the subway doesn't extend, where it's difficult to change from one kind of transport to another, it's so easy to get where you want to go with Mobike," Hu Hong,29,told AFP. She pedals(骑车)to her Shanghai real-estate job.

    However, the schemes have also led to problems such as illegal parking, vandalism(故意毁坏) and theft. Last month, two nurses in Beijing were placed under administrative punishment for five days for putting locks on two shared bikes. And in December, a man who stole a shared bike was sentenced to a 3-month detention(拘留),and fined 1 ,000 yuan by the Shanghai Minhang People's Court.

    " Bike-sharing is a greener method of transportation and provides a user-friendly experience,"said Liu Xiaoming, vice-minister of transport.

    " But it's a combination of online and offline business. Operators are usually strong in online services, but lack offline business experience, which causes problems."

    Now, Chinese service operators are trying to solve the problems. For example, a bike- sharing company called Mobike sets a 100-point credit score for each user, with points taken in the case of bad behavior. Once a score drops below 80, bike rental is increased to 100 yuan per 30 minutes, up from 0.5 - 1 yuan.

    Auctions (拍卖行) are everywhere. Here are just a few standouts and some of the areas they specialize in. All have brick-and-mortar (实体的) sales rooms in addition to online buying.

    In earliest times, men considered lightning to be one of the great mysteries (神秘的事物)of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.

    In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (灯泡).

    The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning.

    Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.

    Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day.

    The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.

    With lightning, it is better to be safe than sorry?

    If your life were a book and you were the author, how would you want your story to go? That's the question that changed my life forever.

    At the age of 19, I became a massage therapist(治疗师). For the first time in my life, I felt free, independent and completely in control of my life. That is, until my life took a detour. I was diagnosed with bacterial meningitis. Over the course of two months, I lost my spleen(脾), my kidneys, and both of my legs below the knees.

    One day, I went home. I crawled into bed and this is what my life looked like for the next few months me passed out, escaping from reality, with my legs resting by my side. I was completely physically and emotionally broken. But I knew that in order to move forward, I had to let go of the old Amy and learn to embrace the new Amy. And that is when I began to realize that I didn't have to be small any more. I could be as tall as I wanted or as short as I wanted depending on whom I was dating. And if I snowboard again, my feet aren't going to get cold. And the best of all, I thought, I can make my feet the size of all the shoes that are on the sales shelf. And I did!

    I started snowboarding. Then I went back to work. And then I co-founded a non-profit organization for physical disabilities so that they could get involved in action sports. And just this past February, I won two World Cup gold medals, making me the highest-ranked adaptive female snowboarder in the world.

    Eleven years ago, when I lost my legs, I had no idea what to expect. But if you ask me today, if I would ever want to change my situation, I would have to say no, because my legs haven't disabled me. They've forced me to rely on my imagination and to believe in possibilities, and that's why I believe that our imaginations can be used as tools for breaking through borders, because in our minds, we can do anything and we can be anything. It's belief in those dreams and facing our fears directly that allow us to live our lives beyond our limits.

The gentle giants of our oceans are whale sharks. It's the biggest whale shark and can reach as long as 41. 5 feet, and these amazing creatures are not only the biggest sharks, but they are also biggest fish of any kind.

Whale sharks have a lifespan of 70 years on average, and they spend their days gently swimming in the warm and tropical oceans.

Their teeth are the size of match heads, and while their jaws could be powerful, they have never tended to attack humans. Their teeth play no role in eating, as plankton (浮游生物) does not need to be chewed. They are to be found in numbers in the warmer oceans and they prefer the deep waters of open oceans. They tend to travel alone.

Several times a year they gather together in certain spots where plankton is plentiful. Those areas are all within a 30°north or south latitude from the equator. Sadly whale sharks are targeted by commercial fisheries at those spots.

How easy it must be for the fishermen to catch those beautiful creatures who can only swim at 3. 5 miles per hour! So great a loss in numbers have they suffered that whale sharks are now listed as one of the endangered species. Some countries have started to take measures to protect the whale sharks from extinction.

The Philippines, India and Taiwan have all banned the fishing, selling, importing and exporting of whale sharks for commercial purposes. However, the law doesn't seem to be effective because the hunting and killing still goes on today, especially in Taiwan and the Philippines. Each whale shark can fetch around $21,000. In parts of Asia they are known as the "money shark".

The mighty dollar wins again at great cost to our habitat, and we will not know what we have lost until we have lost it forever. Therefore, it is high time for us to do something for the whale sharks.
