Read the article and select the best answer. Article: Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body. Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic . To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs. Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we've had enough to eat; as a result, people often overeat . Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells. The body's metabolism becomes inactive, and then result is weight gain and obesity. The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common. To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize (...)the acid already accumulated in body. Eating the right types of raw and whole foods can help. it's also important to restore your enzyme balance. You need to identify and avoid the foods that... Question: . Processed foods are unhealthy because they _ Options: A: destroy body's cells B: are difficult to digest C: may lead to obesity D: stop body's metabolism

People often put these flags on top of houses, or leave them where a vehicle accident happened. They prevent evil spirits from injuring people again. A wind-horse flag can be white, yellow, red, green or blue. These five colors symbolize the five elements that form the world; earth, water, fire, wind and sky. Another explanations that red is the sun, green is the grassland, yellow is the earth, blue is the sky, and white is the cloud. The wind-horse flag originated with a monk who obtained a scripture from India. When he crossed a river, he carelessly dropped the scripture into the water. He quickly saved the scripture and spread it out on a big rock to dry as he sat in meditation . Suddenly violent thunder sounded like drums. The monk felt liberated from all of his sadness, and when he opened his eyes he saw that the scripture had been blown into the sky by a strong wind. Finally, he went straight to heaven. In order to honor the spirit of the monk and the Buddhist scripture, people printed the scripture on a piece of cloth and hung it up between the sky and the earth as though the scripture was flying in the sky. We also know why people put the wind-horse flag on the top of mountains and houses. The Tibetan ancestors had a very great idea about chanting scripture. They thought people not only could chant scripture, but also the five elements. The wind-home flag is a good example of how they use the wind to blow the flag, which means that the wind also chants scripture. Question: According to the passage, the origin of the wind-horse flag is based on _ . Options: A: a historical event B: an ancient custom C: a religious tale D: a vehicle accident

Q: Read the article and select the best answer. Article: Many people may not believe it, but this is what is happening: polar bears are dying out! They are dying because they are losing a great deal of habitat due to human incursion and global warming. They are dying because of starvation as well. With the sea ice they depend on for survival shrinking, it is becoming increasingly difficult for them to find food. An ecosystem is highly dependent on all of its parts, and removing even a single species can result in serious consequences. Polar bears are at the top of the predators where they live. They play an important part in the ecosystem. They feed on seals, fish and deer. Several other animals depend on the kill of polar bears. The failure to save polar bears might result in loss of these predators. In addition, all large predators perform a very important function in their habitat: helping to control the populations of other species. When an animal group loses its natural predators, its population will rise rapidly, having a direct result in population decrease of other groups. A huge boom in population of Arctic seals would have a direct effect on the prey of seals, and could reduce numbers of certain types of fish. This could also have a direct effect on humans, who might have to compete with Arctic seals for food supplies from fish. Lack of polar bears could eventually affect human food supply. Human beings shall save polar bears to ensure the food supply. There is no doubt that we should save polar bears. However, there is still another question: can they be saved? This is a matter that scientists debate because of rapid degradation of the polar bear' environment in recent years due to warming temperatures. It is estimated that if the bears cannot adapt to changing climates, they might die out before the end of the 21stcentury, with about 50% of the animals disappearing by 2050. So time is running out! There are some things that may help slow down global warming and help delay extinction of polar bears. These include finding new energy sources... Question: Why do we need to save polar bears? Options: A: For the predators in the ecosystem. B: For the seals in Arctic Circle. C: For our own source of food. D: For our environment.

Read the article and select the best answer. Article: Parents are creating an "I want it now" generation by satisfying children's every demand at Christmas, say experts. Youngsters in Britain are becoming increasingly selfish, claim the education analysts. Behavioral consultant Chris Calland said: "Parents want to make Christmas into magical fairytale for their kids. "There's nothing wrong with that. The problem arises when it means always giving into all our children's demands--- even if they are beyond our price range or not age-appropriate." Ms Calland, who runs "Santa Says No" style sessions with colleague Nicky Hutchinson, added: "Many of us go into so much debt providing the gifts our children want that we spend the rest of the year paying off the bills. But so often the gifts we've carefully wrapped, once opened, are just pushed away because the very thing our little boy or girl was once so desperate for, they have now lost interest in." Ms Calland and Ms Hutchinson have drawn up a list of guidelines to help parents manage their offspring's Christmas lists this year. They say that adults can actually improve their relationships with their children by resisting "pester power". Ms Calland said: "All too often we say yes because we want an easier life when the fact is that we're only building up problems for the future. We are helping create a generation of youngsters who are blind to the needs of others and the necessity of hard work. "Children learn fast--- if we sometimes change our mind, they quickly realize it might be worth lying on the floor and screaming for it. Make sure you and your partner are working together on this. Be consistent. And try not to get caught up in competition with other families or friends. Question: What is the main problem with the " I want it now" generation? Options: A: They are quite self-centered. B: They like to live in fairy tales. C: They waste a lot of money on gifts. D: They can't keep their interest in gifts.
