Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren't doing any more physical activity than usual. Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men's blood pressure also dropped, which the researchers believed was due to weight lost. Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual--about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic   rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data. Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile. Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn't practical as a... In what manner does Lippl talk about the way of losing weight by spending holidays on mountains? A) casual B) inaccurate C) uncertain D) confident

Each Sunday, people can hear the music of the Mission Dolores Basilica in San Francisco. The Spanish missionaries built the church in 1791. It was the start of a special kind of neighborhood: the Mission District. The area is a place with a long and varied history. One community member says that it's important for people to understand the many levels of history in the neighborhood. He feels that _ is a big part of understanding what it means to be a real San Franciscan. One of the most interesting parts of the district is its people. Over the years, immigrants have come to the area from Ireland, Germany, and Italy. But the most recent immigrants are mainly from Latin America. It's easy to see the style that these recent additions give to the neighborhood. You can see it in the art on the walls, taste it in the food, and hear it in the music! Juan Pedro Gaffney, the director of the Spanish Choir of San Francisco, says that the people there share the pain and the happiness of their friends and family members and that music has always been a basic part of cultural identity in the district. He feels that the music of the district is colorful and lively. But it isn't just its music that's colorful and lively. Its art is full of life as well. The local art community stays close to the area's culture and tradition. A local arts organization often leads people on walks through the district. They visit streets like Balmy Alley, which is famous for its murals  . Even though the meanings behind the murals are always changing, they are still very powerful. One artist explains that they are fighting for fairness in the community and to help the environment through murals. Apparently, they're something the community likes. Many of these artists feel that the district is a successful neighborhood where new immigrants are welcome. "People see that they're not so different from each other," says one artist. "There are a lot of things that bind the immigrants through culture and tradition." What would be the best title for the passage? A) The Mission Dolores Basilica B) A Special Type of Neighborhood C) Music of the Mission District D) The Spanish Choir of San Francisco

Ques: Greenspace facilities   are contributing to an important degree to the quality of the city environment. Fortunately it is no longer necessary that every lecture or every book about this subject has to start with the proof of this idea. At present it is generally accepted, although more as a self-proved statement than on the base of a closely reasoned scientific proof. Recognizing the importance of greenspaces in the city environment is a first step on the right way, this does not mean, however, that enough details are known about the functions of greenspace in towns and about the way in which people are using these spaces. As to this subject I shall within the scope   of this lecture, enter into one aspect only, namely the recreative function of greenspace facilities. The theoretical separation of living, working, traffic and recreation   which for many years has been used in town and country planning, has in my opinion resulted in more attention for forms of recreation far from home, while there was relatively little attention for improvement of recreative possibilities in the direct neighborhood of the home. We have come to the conclusion that this is not right, because an important part of the time which we do not pass in sleeping or working, is used for activities at and around home. So it is obvious that recreation in the open air has to begin at the street door of the house. The city environment has to offer as many recreation activities as possible, and the design of these has to be such that more required activities can also have recreative aspect. The very best standard of living is nothing if it is not possible to take a pleasant walk in the district, if the children cannot be allowed to play in the streets because the risks of traffic are too great, if during shopping you can nowhere find a spot for enjoying for a moment the nice weather, in short, if you only feel yourself at home after the street door of your house is closed after you. For many years town and country planning has   _  . A) brought living areas and places of entertainment close together B) separated recreation facilities far from home C) improved recreative possibilities in the neighborhood D) enabled people to reach the best standard of living
Ans: B


Ques:Many people consider their pets members of the family and are very sad when they die, but what if you could clone your dog, cat or bird? A scientist in New Orleans, who has proved his ability to clone other animals, is now offering the possibility to pet owners here in Wisconsin. Scientists have not been able to clone dogs, cats or other pets, but if and when the time comes, several companies will be ready and able to do the job. The question is: Are you ready to clone your pet? Brett Reggio is betting on it.He is working on his Ph. D at Louisian State University. He's successfully cloned a goat five times and wants to try the process on family pets.  So he started a business called Lazaron. "What Lazaron provides is the first step in the cloning process. "He said."It's for curing and storing the fiberglass cells that will be used for cloning." "Your first reaction is yeah! I think I'd like that." said Donna Schacht, a pet owner. "I don't believe you can ever replace a special love," pet owner Paulette Callattion said. Most pet owners will tell you freezing your pet's  DNA in hopes of one day cloning it is a personal decision. Scientists say that cloning your own pet doesn't mean that the offspring  will have the same intelligence, temperament  or other qualities that your pet has. Brett Reggio started a business in order to   _  . A) clone pets for people B) store the DAN of people's pets for cloning one day C) make pets members of a family D) collect different ideas on cloning from people
