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!

    The Lantern Festival is a traditional Chinese festival with great significance, which is on the 15^th of the first lunar month, marking the end of New Year celebrations. Here are several things you should know about the Lantern Festival.

    The Origins of Chinese lanterns

    The origins of Chinese lanterns date back to the Stone Age. The coming of the Bronze Age saw the development of various kinds of lanterns, of which palace lanterns were the most fascinating{#blank#}1{#/blank#}Various lantern festivals became a hit during the Sui Dynasty, and during the Southern Song Dynasty, the custom of writing riddles on lantern arose. During the Qing Dynasty, magnificent exhibitions of lanterns were held in the capital city.

    Eating small dumpling balls

    Just as the name implies, an important part of the Lantern Festival, or Yuan Xiao Festival, is to eat small dumpling balls made of sticky rice flour. We call these balls Yuan Xiao, or Tang Yuan.{#blank#}2{#/blank#}The dumpling symbolizes family unity, completeness and happiness.

    {#blank#}3{#/blank#}

    When it comes to the Lantern Festival, “Guessing lantern riddles” is an essential component. Lantern owners will write riddles on a piece of paper and post them on the lanterns in advance. If visitore can answer the riddles, they will get a little gift.

    Watching fireworks

    At night, in addition to lighted lanterns, fireworks form a grand scene. Most families save some fireworks from the Spring Festival and set them off during the Lantern Festival.{#blank#}4{#/blank#}

    The English language has a lot of words which can be used in many different ways and in many different expressions.

    One such example is the word matter. In fact, matter can mean just about anything. It could be one of the most useful words in the English language.

    Let's get to the heart of the matter —a matter of principle(原则).

    If someone says that you owe(欠) him $50, but you don't, a friend might say, “Well, you could pay him the $50. It's not that much money. Then you won't have to hear him say it anymore. But if you do not owe him the money, do not pay him the money. It's a matter of principle.

    There is another way to use the word matter. But be careful with your choice of words.

    If you ask someone, “What's the matter?”, it shows you are worried about the other person. But saying, “What's the matter with you?” has a completely different meaning. And it usually sounds rude (粗鲁的). In fact, when you say, “What's the matter with you?” you are suggesting that the person did something wrong or stupid.

    Another expression that could sound rude is to say, “It doesn't matter to me.” Here, it depends on the context, and how you say it.

    Let's say you tell someone that a friend just got a big raise at work. That person answers with, “It doesn't matter to me.” Here, it means he or she does not care. And it sounds rude.

    But saying, “Oh, you pick where we eat dinner. It doesn't matter to me.” does not sound rude. In this situation, “it doesn't matter” shows you are easy-going(随和的).

    No matter how you look at it and what you say, matter is a very useful word. And it's only a matter of time before you will become an expert on the use of matter.

    If you are interested in studying at an American university, you have to take the Test of English as a Foreign Language. The test is widely known as the TOEFL. It is the most widely used language exam for American universities.

    There are two major kinds of the TOEFL test. The first is the IBT，or Internet based Test. It is offered in most of the world and accepted by nearly every university and scholarship program in the United States. The other kind of the test is called the Paper­based Test or PBT. The PBT is less costly to take and does not require use of the Internet.

    But how to get started with TOEFL? Here are some tips.

    ⒈Plan ahead — It takes a long time to improve your TOEFL score. Do not expect a big lift in your test results after two weeks. You will have to spend a lot of time and energy.

    ⒉Master the basics first — You should have to be good at basic English before you take the test. If you score below 500 on the PBT or 70 on the IBT, study for a few months and come back to the TOEFL later.

    ⒊Get a study guide — It is easy to find study guides for the IBT. Pearson, Barron's, ETS, and Kaplan all produce quality materials, take a practice test once or twice a month. The best study guides will have explanations in the answer key.

    ⒋Use outside resources — Remember, you are learning a language, not a test. You can improve your TOEFL score by making English part of your daily life. Some simple ways are listening to English speakers, watching movies and reading newspapers. Some others are reading English textbooks, sending and reading text messages in English, and writing online in English.

    The best way to do well on the TOEFL is to know English well. The real goal of the test is to measure how well a student can communicate in English­speaking classroom.

On paper, hydrogen (H2) looks like a dream fuel. Coal, oil, and natural gas produce carbon dioxide, which warms the earth when burned, Hydrogen produces pure water. Hydrogen packs more energy into less space than a battery (but certainly less than petrol) . Also, empty tanks (燃料箱) can be refilled with hydrogen much faster than refilling empty batteries with electricity.

While in practice, things are trickier. Storing a meaningful amount of hydrogen gas requires pressing it several hundred-fold. Changing it into the liquid form is another option, but it should be cooled to-253C. Both processes require a heavy and strong tank. While a 700 bar tank is acceptable for a city bus or a truck, adapting it for use in small vehicles is very difficult because the pressure during refilling would be too great.

The solution? Powerpaste.

A German team of researchers, led by Marcus Vogt, have come up with an interesting "powerpaste", which can store hydrogen energy at atmospheric pressure, ready for release when needed. It is so named because it comes in tubes and looks like toothpaste (牙膏) , not in its traditional form of gas.

The main ingredient (原料) of the paste is magnesium hydride, a substance that reacts with water to form hydrogen. The escaped hydrogen can then be directed into a fuel cell, where it reacts with oxygen from the air to produce electric power.

Refueling is very simple, as instead of going to a filling station, drivers and riders can simply replace an empty tube with a new one and refill the water tank.

Given that powerpaste only begins to break down at temperatures of around 250℃ it remains safe even when a vehicle stands in the baking sun for hours.

However, we will have to be patient. Just because researchers have succeeded in developing a new fueling way does not mean that we can expect to see such vehicles on the road anytime soon. It will indeed be several years before this concept is turned into reality.
