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. Question: In which countries does most part of virtual water come from outside? _ - Kuwait and the Netherlands - China and the United Kingdom - America and the Netherlands - Israel and America
Kuwait and the Netherlands

Read the following article and select the best answer. Article: If you're a male and you're reading this, congratulations: you're a survivor. According to a survey, you're more than twice as likely to die of skin cancer than a woman, than nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you'll die on average five years before a woman. There're many reasons for this -- typically, men take more risks than women and are more likely to drink and smoke--but perhaps more importantly, men don't go to the doctor. "Men aren't seeing doctors as often as they should," says Dr. Gullotta. "This is particularly so for the over-40s, when diseases tend to strike." Gullotta says a healthy man should visit the doctor every year or two. For those over45, it should be at least once a year. Two months ago Gullotta saw a 50-year-old man who had delayed doing anything about his smoker's cough for a year. "When I finally saw him it had already spread and he finally died from lung cancer," he says. "Earlier detection and treatment may not have cured him, but it would have prolonged his life." According to a recent survey, 95% of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group. "A lot of men think they can never defeated," Gullotta says. "They only come in when a friend drops dead on the golf course and they think, 'Geez, if it could happen to him, ...'" Then there's the ostrich approach. "Some men are scared of what might be there and would rather not know," says Dr, Ross Cartmill. "Most men get their cars serviced more regularly than they service their bodies," Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups. Regular check-ups for men would inevitable place strain on the public purse, Cartmill says. "But prevention is cheaper in the long run than having to treat the diseases. Besides, the ultimate cost far greater; it's called premature death." Question: Why does the author congratulate his male readers at the beginning of the passage? - They are sure to enjoy a longer and happier life. - Their average life span has been considerably extended. - They have lived long enough to read this article. - They are more likely to survive serious diseases today.
They are more likely to survive serious diseases today.

(Question)
Read the following article and select the best answer. Article: 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 Question: 61.
