All around the world, shoppers flock to Wal-Mart to buy everything. In Texas, they come for another reason: to see the wind turbine , which supplies 5% of the store's electricity. It along with other facilities, such as exterior walls coated with heat-reflective paint, makes this Wal-Mart a green giant. The laws of economics suggest that Wal-Mart, with 5, 200 stores worldwide, influences everything including the price of all kinds of goods. It throws its weight behind environmental responsibility, and the impact could be amazing. "One little change in product packaging could save 1, 500 trees," says Wal-Mart CEO Lee Scott."If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day you have made a huge difference." Scott wants Wal-Mart to do its part too. He has promised to cut the existing greenhouse-gas emissions over the next few years and promised to construct new stores that are more efficient. He wants Wal-Mart's fleet of more than 7, 000 trucks to get twice as many miles per gallon by 2015. Factories that show Wal-Mart they're cutting air pollution will get preferential treatment in the supply chain. Wal-Mart says it's working with consumer-product manufacturers to reduce their packaging and will reward them if they do so. Some people may doubt it is a bid to attract attention from Wal-Mart's controversial labor and health-insurance practices. But it's not just window dressing, because Wal-Mart sees profits in going green. Scott says, " _ . We don't go where we don't think there's a great interest in change." Like Bill Gates, who started his charitable foundation, Scott happens to be promoting Wal-Mart's image at a time when his company's reputation is declining. He acknowledges that he launched the plan partly to shield Wal-Mart from bad press about its contribution to global warming. "By doing what we're doing today, we avoid the headline risks that are going to come for people who did not do... We can infer from the passage that _ . A) Lee Scott is Wal-Mart's CEO B) there are 5, 200 stores in the world C) Wal-Mart has a great influence on the world market D) Wal-Mart has more than 7, 000 trucks all over the world

Today, they're back again in all colours, lengths and materials. In fact, today's women can wear all types of clothes on almost any occasion. While all of these changes were taking place in women's fashions, men's clothing remained almost the same until a few years ago. And, in fact, most men are still dressed in the kinds of clothes they used to wear. The passage tries to tell us _ .

Ques: Imagine what you could do with a machine that could make things disappear. For inspiration, you could read some books. In the books of J.R.R. Tolkein, Bilbo Baggins finds a ring that can make him disappear. Of course, there's also poor Harry Potter, who used his invisibility cloak to hide from danger. Now that you've got some ideas, it's time for the hard part: building the cloak. To do that, you have to give up science fiction and turn to real science. An invisibility cloak has to cheat anything or anyone who might be watching. In order to understand how something can be seen, it's important to understand how we see. Human beings can only see objects that reflect light waves. These waves enter the eye and are then processed by the brain. However, if an object doesn't reflect light, then the waves don't enter the eye, and the brain doesn't process. So building an invisibility cloak is building something that doesn't reflect light. Cummer was part of a team of scientists from Duke University, including David Smith and David Schurig, who built the world's first version of an invisibility cloak. They had been inspired by the work of a British physicist, John Pendry. He in May said that an invisibility cloak was possible and Pendry was not the only one thinking about a disappearing act. At the same time, a Scottish physicist, UIf Leonhardt published a paper on building invisibility equipment. "It wasn't easy," says Cummer. "As often happens in science and research, it didn't work very well the first time. That first cloak didn't work like Harry Potter's --- the scientists didn't actually see anything disappear. So the research is still under way. " Cummer and other scientists got the idea of building an invisibility cloak from _ . A) the film Harry Potter B) the work of a British physicist C) a paper published by a Scottish physicist D) the book of J.R.R. Tolkein
Ans: B
During communication, "words" express only 7% of meanings between people. About 23% of meanings are from the "tone of voice" and 70% of meanings come from "body language". So next time you want someone's attention--try body language instead. Everyone does it, and most interestingly--most do it unconsciously. You may wonder: "Does that mean I have to study psychology to succeed in reading body language?" The answer is "no" because most people are already body language readers. It's a skill developed since we're babies--think of how most babies can recognize facial expressions and get attention without saying anything. That is, you needn't spend most of your time practicing some of your body language cues ! However, you should know that the context is king. It suggests that, depending on the context of the situation, people will hide body language cues. So sometimes cues can be tricky: a woman who locks her arms may think you are boring--or she may just feel cold. You must learn to read into the context as well as the cues. Sometimes people care more about their body language cues. For example, poker players will consciously hide more of their body language cues. The first place to start when reading a person's body language is the face. The easiest way to hide your feelings is to cover your face. This is why it's sometimes hard to tell if an Islamic girl likes you. If the eyes are the windows of the mind, the eyebrows are the windows of the eyes. So, notice how a person's eyebrows will generally rise when they meet someone, see something they like or are surprised at. Eyes generally smile along with the mouth when someone is happy, so everyone knows "^ . ^". Who will hide their body language cues on purpose according to the text? A) Scientists B) Farmers. C) Teachers. D) Poker players.
