As the saying goes, man struggles upwards; water flows downwards. Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn't the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn't the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of "virtual water ". We typically think about water as the liquid that flows from a tap. However,92%of the water used by people goes into growing crops,according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world. For example, consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310liters of the water--about 95%--is used to grow and process the ingredients .Another 4%goes into the packaging and labeling. In Hoekstra's calculation, when one country produces a half-liter of soda and sells it abroad,it exports as much virtual water as would fill a large refrigerator. According to Hoekstra's new report,dry countries like Israel and Kuwait,both in the Middle East,get the majority of their virtual water from other countries,through imported products. More surprisingly, some wetter countries,like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries. In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products. The example of a sugary soft drink in Paragraph 3 is given to show _ . A) how drinks are shipped B) how virtual water is exported C) how virtual water is used D) how drinks are made

If you want to avoid making impulse and unnecessary purchases,then just keep your hands away from tempting products. According to new research,individuals who touch possible items in stores are more likely to have an increased desire to purchase them than those who keep their hands off the products. Suzanne Shu and Joann Peck,marketing professors at the University of Wisconsin's business school conducted studies on the connection between touch and feelings of ownership and the effect of perceived ownership on the value placed on an object. For one of the experiments,the experts placed two products,a Slinky toy and a coffee mug in front of the volunteers who were undergraduate students. About half of the participants were allowed to touch the products,while the other half were asked not to touch them. The volunteers then were asked to express their sense of ownership of the products and to report how much money they were willing to pay for each. The results showed that those students who were allowed to touch the objects,reported significant increased levels of perceived ownership. They also expressed a desire to pay more money to obtain the products. The investigators also discovered that a sense of very pleasant feelings when touching products,determined how much money consumers were willing to pay. However,if the object did not feel pleasant to the touch,it significantly decreased the amount the buyers were willing to pay. Researchers said that many stores have already followed the right path. But what can be done while shopping online,when touching of an item is not possible? In this case,the experts say,just picturing in mind that they are touching it and then owning it,will cause greater feelings of ownership,and thus the consumers will be more likely to make a purchase. When you touch an object,you immediately feel some kind of a connection to it,according to the researchers. That connection stirs up an emotional reaction. And that emotion can make people buy something they would never even... What led the researchers to conduct this study? A) To illustrate the connection between touch and feelings of ownership. B) To share their good ideas about avoiding impulsive consumption. C) To develop marketing strategies for trade companies. D) To satisfy customers' social needs when shopping.

A letter to Edward,a columnist Dear Mr. Expert, I grew up in an unhappy and abusive home. I always promised myself that I'd get out as soon as possible. Now, at age 20, I have a good job and a nice house, and I'm really proud of the independence I've achieved. Here's the problem: several of my friends who still live with their parents wish they had places like mine--so much so that they make mine theirs. It started out with a couple of them spending the weekends with me. But now they seem to take it for granted that they can show up any time they like. They bring boyfriends over, talk on the phone and stay out forever. I enjoy having my friends here sometimes--it makes the place feel comfortable and warm--but this is my home, not a party house. I was old enough to move out on my own, so why can't I seem to ask my friends to respect my privacy ? Joan Edward's reply to Joan Dear Joan, If your family didn't pay attention to your needs when you were a child, you probably have trouble letting others know your needs now. And if you've gathered your friends around you to rebuild a happy family atmosphere , you may fear that saying no will bring back the kind of conflict you grew up with--or destroy the nice atmosphere you now enjoy. You need to understand that in true friendship it's okay to put your own needs first from time to time. Be clear about the message you want to send. For example, "I really love your company but I also need some privacy. So please call before you come over. " Edward 60. We can infer from the first letter that _ . A) Joan thinks her friends more important than her privacy B) Joan doesn't like the parties at all C) Joan's friends visit her more often than expected D) Joan dislikes the boyfriends her friends bring over
