"Have you ever heard that it's impossible to fold a piece of paper more than seven times? Actually, it is just a popular myth.
The myth refers to folding a piece of paper in half many times in any direction. The paper is folded in half. Try it for yourself with a piece of notebook paper. ____ But when you make the fifth and sixth folds, you'll notice that it's increasingly hard to fold the paper. Why does it happen? Because the number of the layers (层) of paper doubles with each fold. For example, after the sixth fold, you're left with 64 layers of paper. If you have strong hands, you may be able to make that seventh fold. If you start with a piece of paper that is 0.01 centimeters thick, it'll be as thick as a notebook after seven folds. And it would seem impossible to make more folds. At this point, you may be thinking that the paper-folding myth doesn't sound much like a myth.
However, in 2002, a high school student named Britney Gallivan proved the idea wrong. Britney successfully folded a 1.20-meter-long roll of toilet paper 12 times (note that she used single-direction folding). She also developed a math rule. This is convenient. It allows you to find out the maximum (最大的) number of possible folds based on paper thickness, paper length, and direction of folding.
Since Britney's success, many people have managed to fold a single piece of paper more than 7 times. Students even folded a piece of toilet paper a total of thirteen times. The toilet paper they used was about 4,000 meters long!
Wind is a powerful force in nature. Wind energy may cause great waves in the world's oceans. Its power can be used to create electricity for cities and the countryside.
Wind can also power many expressions in American English. Let's start with a simple one. If you run like the wind, you can run very fast. After running, sometimes you can be full of energy.
If you are doing something difficult, it is good to have the wind at your back, for example, when you are sailing. In this way, it is easier to go forward.
Knowing the direction of the wind is one of the most important parts of sailing. When wind fills a sail, it makes the boat go faster. If you take the wind out of someone's sails, you prevent them from reaching their goals.
Let's turn from sailing to music. Many songwriters use the image of wind in their songs. If an idea is blowing in the wind, it is under discussion but has yet to be decided. When a singer sings"you don't need a weatherman to know which way the wind blows", he means you know what is going on, and he tells you to trust yourself as you can find something out on your own.
Now you know which way the wind blows. Then how can you use these expressions properly? First, read them aloud and keep them in mind. Then, practice using them and test yourself. You know, practice makes perfect.
