According to EMTP and Stat Gear CEO Avi Goldstein, every driver should be taught how to get out of a car when it becomes submerged in water.

“Accidents and natural disasters often occur so quickly that it's essential for drivers to be prepared,” says Goldstein. “In this case, preparation is simply knowing what should be done before it happens.”

        Goldstein offers the following lifesaving tips:

1.Try to stay calm. The worst thing you can do is become overly agitated and      panicked.

2. Don't try to open the door. This will cause the car fill with water very quickly.

3. Unfasten your seat belt or cut it if it's jammed.

4. Help free anyone else in the car.

5. Use a window punch — preferably spring-loaded. It's nearly impossible to break a car window with your hands or feet.

6. Exit through the broken window and swim up to safety.

      “Every car should be equipped with a window punch and seat belt cutter, but they are usually completely forgotten by car owners,” says Goldstein. For example, the T3 Tactical Auto Rescue Tool from Stat Gear features a 440c stainless steel serrated knife, seat belt cutter, spring-loaded window punch and LED light.

       Goldstein asserts that the T3 or another similar tool should always be within arms length of a driver. “If for any reason a driver becomes pinned into his or her seat, emergency tools need to be within reach--otherwise they are useless. They will do you no good in your trunk or backseat.” The following is a quick demonstration on how to escape a sinking car with a baby on board.

    China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities.

    First, you must be punctual (准时的) with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late!

    It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surpri if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have “dress down Friday”, when people wear casual (随便的) clothes.

    In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names.

    In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive（肯定的） things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business!

    So, use these tips, and you will be on your way to a successful international business career!

Why Mars (火星) is New Settlement

    Is it possible to live on other planets? The United States government is taking a serious look at the moon and Mars as potential places for future human settlement. The moon could serve as a training ground for later journeys to Mars. Currently, with Mars becoming the eventual long-term goal, serious questions exist as to whether the dangers of the settlement on the moon are too extreme and unnecessary.

    One major reason the settlement on the moon is too dangerous is the difference between the atmosphere environment of the moon and Mars. Atmosphere is important because it protects humans and all other life from a continuous attack of radiation (辐射) caused by sources such as the sun. This radiation is especially dangerous to humans because it increases the risk of cancer and can negatively change DNA. The fact that the moon has no atmosphere can cause great harm to human beings. Although Mars' atmosphere is significantly thinner than Earth's, at least it has one and would create some sort of protective barrier for humans.

    Another important characteristic necessary for human settlement is natural resources like water, of which the moon is believed to have none. Mars, however, contains vast quantities of water ice, dry ice, and also snow. There is also sufficient evidence that water once existed at the surface of Mars and might return in the future if the planet warms. With increased technologies, the potential for settlers to remain on Mars by being increasingly self-sufficient makes Mars a much more attractive goal as the space settlement than the moon.

    Future settlers will not only benefit from potential water on Mars; the planet is also rich in other natural resources such as oxygen, hydrogen, and minerals, which can be well used in productive ways.  For example, hydrogen can be used as fuel, and it can be combined with nitrogen (氮气) to form new materials necessary for human settlement. Due to these advantages,

    Mars would be a more successful planet for exploration and settlement because it contains the basic resources necessary for humans to survive.

    Since the environment of Mars is more similar to that of Earth and it contains resources necessary to  help  life  exist,  it should  be  the  only option for any kind of long-term human settlement. The settlement on Mars would not only be a milestone in space but also an excellent chance for mankind to improve itself from past adventures on Earth and preserve and make the best use of the natural resources Mars has to offer.

    Alexa is a form of artificial intelligence, or Al for short. Many people start their mornings by asking Alexa for the weather forecast or the latest news. A device (设备)that houses Alexa can also play music from your favorite playlists, keep a shopping list, order takeout food, answer questions, send voice messages and even run "smart" home controls.

    Training AI systems to respond to problems with human-like intelligence—and learn from their mistakes —can take months, or even years. Consider Alexa and similar software, such as Apples Siri. To do the tasks its human owners ask, these systems must make sense of and then respond to sentences such as, "Alexa, play my Ed Sheeran playlist" or "Siri , what is the capital of India?"

    Computers can't understand language as it is spoken by people. So AI researchers must find a way to help humans communicate with computers. The technology used to get computers to "understand" human speech or text is known as natural language processing. By natural language, computer scientists refer to the way people naturally talk or write. To teach an AI system a task like comprehending a sentence or responding to a person's last move in a board game, scientists need to feed it lots of examples.

    AlphaGO is an AI system designed by Google that has beaten a human champion, Lee Sedol, at the strategy(策略)board game Go. To train AlphaGo, Google had to show it 30 million Go moves that people had made while playing the game. Then AlphaGo used what it learned to analyze those plays as it played against different versions (版本)of itself. During this practice, the program came up with new moves —ones never seen in games between people.

    Computers, software and devices that are powered by AI can do much more, however, than just play board games and music. And one day they could make our life much easier and much more interesting.
