[EX Q]: Article: LONDON ( Reuters)-- Ecotourism is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to researchers. Biologists and conservationists are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying. "Evidence is growing that many animals do not react well to tourists in their backyard," New Scientist magazine said. The immediate effects researchers have noticed are changes in behavior, heart rates, or stress hormone levels but they fear it could get much worse and over the long term "could endanger the survival of the very wildlife they want to see". Although money produced through ecotourism, which has been growing at about 10--30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited and based on environmentally friendly policies, according to the magazine. "The transmission of disease to wildlife, or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding," said Philip Seddon, of the University of Otago in Dunedin, New Zealand. Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by ecotourists are producing smaller babies. Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started. "The animals' welfare should be very important because without them there will be no ecotourism," said Rochelle Constantine of the University of Auckland in New Zealand.

[EX Q]: Article: People in cities all over the world shop in supermarkets. When you enter the supermarket, you see shelves full of food. You walk in the aisles, pushing your shopping cart. You probably hear soft, slow music in the supermarket. This kind of music is playing to relax you and make you walk slowly. Thus, you will probably stay longer and buy more food. Where do you go in the supermarket when you first arrive? Many people go to the meat section first. This area of the store has many different kinds of meat. Some kinds are expensive and others are not. Usually, some kinds of meat are on sale. So it has a special low price. The manager of the store knows where the customers usually enter the meat section. The meat on sale is usually at the other end of the section, away from where the customers enter. If you want to buy this specially priced meat, you have to walk by the more expensive meat first. Maybe you will see something that you want to buy before you reach the cheaper, inexpensive meat. Then you will spend more money in the meat section. The diary section sells milk that is low in fat. Some supermarkets sell three different containers of low-fat milk. Each container looks different, but each contains the same product. One says "1% fat", one says "99% fat free" and one says "low-fat" in big letters and "1%"in very small letters. If you look carefully you can see that all the milk has the same amount of fat, and each container is the same size. The prices of all these three should be the same. However, in many stores these three containers of milk would each have a different price. The store will make more money if a customer chooses the milk that costs the most. Most of the food in supermarkets is very attractive. People often stop to look at the products in attractive containers. But remember, many products will say, "Buy me!". Stop and think which ones are the best value for your money.

[EX Q]: Article: A 13-year-old American boy on Saturday became the youngest climber to conquer Mount Everest, the world's highest mountain. Jordan Romero from Big Bear, California, climbed up the 8,850-meter summit from the Tibetan side. On the same day, a Nepali man, Apa Sherpa, broke his own world record of climbing Everest when he reached the summit for the twentieth time. Apa Shepa's team set off from Nepal's capital, Kathmandu, last month, heading for the base camp on the Chinese side of the mountain. "The team has just called in and believe that they are standing on top of Mt. Everest," Romero's blog said. "Their dreams have now come true. Everyone is happy." The climbing has put Romero one step closer to reaching his goal of climbing the highest mountains on all seven continents . "It is just a goal." Romero said. He had already climbed five peaks , and needs to climb only Vinson Massif, the highest peak in Antarctica, to hit his goal. The youngest person before to climb Everest was 16-year-old Temba Tsheri Sherpa of Nepal. Romero climbed together with a team including his father Paul and three local guides. He wanted to pick a small piece of rock from the top of the world and wear it in a necklace. While Nepal insists that anyone planning to climb Mount Everest must be at least 16, China does not have any age restrictions . Some mountain climbers haven't agreed with the Romero family for letting him try it but his father said the climbing from the Chinese side is less dangerous.
