The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid—we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

    However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ''

    But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

    Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

    Life is comprised emotion and sense. When we were babies we reached the pinnacle(顶峰) of emotion. At that time we asked for everything that we wanted, cried as we were uncomfortable, laughed as we were happy and released our emotions day and night. When we grow up we find that if we want to live in a cozier environment we must be sensible enough to deal with our emotions and relationships. Our world is based on sense and beautified by emotion.

    Sense is the base of life; it builds up the structure of life, and helps us see the real world. And emotion is the invaluable element of life. It adds colorful paint to our life. Lacking sense we may lose the guiding light and lacking emotion we may lose the value of life.

    We admire Da Vinci's Mona Lisa, we are attracted by Michelangelo's The Creation of Man, and we are carried away by Monet's Lotus. Shakespeare's Romeo and Juliet may bring us tears, Victor Hugo's poems can make a maid's love revive, and Jane Austin's stories arouse our dream of holding a party of ladies and gentlemen as an England beauty in the countryside. All of them are people who deserve our respect and showed us sentimental emotion: love, hatred, betrayal, loyalty and so on. They made their works full of emotion, shocked our nerves, and evoked our passions. Somebody may have found their destiny in these works, and surely they influence people time after time. But in fact, though these people or their works have the power to control our mental world, we don't choose them to be our President or Prime Minister. We cannot deny the fact that our world is based on sense and ration. Mark Twain once said that the passion of friendship is so sweet, steady and royal and enduring a nature that it will last through a whole lifetime if neither of the two friends asks the other to lend money.

    Emotion is our nature and sense gives us an eye to live in reality. Only sense makes Jack a dull boy; emotional moments give us vigor and enthusiasm to live and color our life.

    Apple announced its new iPhones last week, but competitors' mobile phones can do many of the same things for less money.

    The new iPhone 8 and X have wireless charging, edge-to-edge glass screen and double cameras. But all of these features are already available in smart phones from China's Huawei and Oppo, and Korea's Samsung. While Apple asks buyers to pay $1,000 for its high-end model, some Asian phone makers can offer similar features for less.

    At one time, Chinese manufacturers copied features and designs from others to produce low-cost phones. But they have now added high-end features to their phones and they control nearly half the global mobile phone market.

    Media MarktSaturn is Europe's biggest electronics seller. A spokesperson for the store told Reuters that,“Huawei is seen as a relevant competitor to Apple and Samsung by covering all major price points and placing big investments in marketing and sales. '' She also said that the Chinese companies Huawei, ZTE, Lenovo and TCL were among the top-10 best-selling smart phones in its stores.

    Chinese manufacturers' fast growth has been fueled by strong sales in China. But they now export 40 percent of their smart phones. That is almost double the number from just three years ago, according to the Hong Kong investment company CLSA.

    Huawei is currently the world's third largest phone maker behind Samsung and Apple. According to research company Canalys, the Chinese company is getting closer to second-place Apple and might overtake it later this year.The Chinese company even made fun of Apple's new facial recognition feature with a Facebook video called "Real AI phone." Huawei plans to show its top-of-the-line Mate 10 phone on Oct. 16. The phone will have artificial intelligence features such as instant translation and image recognition and will cost less than $1,000.    Other Chinese companies are looking to enter the high-end smart phone market.

    There is a very long list of rules for the New York City subway. Don't put your feet on a seat, don't carry open cups of coffee or soda, don't take more than one seat... Those are just a few of the rules. There are hundreds more.

    With so many rules, why is it still unpleasant to ride the subway?

    Some people think that the problem is that no one enforces the rules. Other passengers sometimes try to enforce rules. But you can't rely on them because New Yorkers have unwritten rules against talking to strangers and making eye contact with strangers. How can you tell someone to take her shopping bags off the seat and throw away her Coke without talking to her or looking at her? It is difficult.

    There are other New Yorkers who think that the subway is unpleasant because there are not enough rules. One rider wrote a letter to The New York Times a couple of weeks ago suggesting a few more subway rules. Here are some of the rules that she would like to see:

    —Don't lean on the poles. You prevent other people from holding on. They can fall down.

    —Talk quietly. The trains are already too noisy.

    —Give your seat to elderly passengers or to parents with small children.

    If those unwritten rules of etiquette are written down, will the rude people be more likely to follow them? It doesn't make sense to make more rules that no one will enforce.

    The real problem is that we are forgetting how to be nice to each other. It is embarrassing that we need a rule to tell us to give our seat to elderly passengers. Nobody should need to be reminded to do that.

    I say we stop talking about the rules and try to remember our manners. Let's be nice to each other not because a police officer might tell us to get off the train, but because it is the right thing to do. Then New York City would be more civilized —both above ground and below.
