Read the article and select the best answer. Article: Thirteen can be a challenging age. Not only did I have to adapt to my changing body, I also had to deal with my parents' bitter divorce, a new family and the upsetting move from my country home to a crowded town. When we moved, my beloved companion, a small brown pony had to be sold. I was heartbroken and terribly lonely. I couldn't eat or sleep and cried all the time. Finally, realizing how much I missed my pony, my father bought me another horse, Cowboy. Cowboy was without doubt the ugliest horse in the world. But I didn't care. I loved him beyond all reasons. I joined a riding club. When Cowboy and I entered the events where the horse was judged by appearance, we were quickly "shown the gate". I knew nothing could turn Cowboy into a beauty. My only chance to compete would be in the timed speed events. I chose the jumping race. For the whole next month we practiced running and jumping for hours in the hot sun and then I would walk Cowboy home, totally exhausted. All of our hard work didn't make me feel confident by the time the show came. One girl named Becky rode a big brown horse in the race events. She always won the blue ribbons. I sat at the gate and sweated all out while I watched Becky and her horse charge through the court and finish in first place. My turn finally came. At the signal, we dashed toward the first fence, jumped over it without trouble and raced on to the next one. Cowboy then flew over the second, third and fourth fences like a bird and I turned him toward the finish line. No cheers filled the air. The end of our run was met with surprised silence. Cowboy and I had beaten Becky and her fancy horse by two seconds. I gained much more than a blue ribbon that day. At thirteen, I realized that no matter what the odds, I'd always come out a winner if I wanted something badly enough to work for it. I can be the owner of my fate. Question: It can be inferred from the story that _ . Options: A: all of their hard training was totally in vain B: a blue ribbon must be the second highest prize C: Cowboy lost in the event of being judged by appearance D: both Becky and the author won in the jumping event

Article: The health and welfare of every person in America will be affected by global warming, especially children, the elderly and the poor, according to a new White House science report. The report said every region of the country will suffer worse health from heat waves and drought. _ It predicts an increase in diseases spread by tainted food, bad water and bugs . The report concludes that climate change causes real risk to human health and human system that supports the way of life in the United States. Man-made global warming is caused by greenhouse gases from the burning of fossil fuels. At current emission levels, global temperatures are likely to rise by about 2 degrees by midcentury and about 7.5 degrees by the end of the century. The most vulnerable Americans -- the poor, elderly, sick, very young and immigrants -- will suffer more. That's at least 10 percent of the country's population, probably more. It will be tougher for these people to get enough health care for climate-related illnesses, to cool down in heat waves, to escape extreme events such as Hurricane Katrina, and even to get enough food. While every region of America is vulnerable to global warming's health and welfare effects, more people are moving to coastal regions, which are most vulnerable to climate change because of drought and hurricanes. Question: Which of the following is NOT true according to the passage? Options: A: Global warming is caused by human beings. B: It is wise for the Americans to move into coastal regions. C: Global temperatures are increasing year by year because of carbon dioxide. D: At least one tenth of Americans are more likely to suffer climate-related illnesses.

Adult males can measure more than 9 feet in length and weigh between 770 and 1,430 pounds. The bear's body and neck are elongated, and the head is narrow and long with small, rounded ears. Polar bear populations can be found in northern Canada, Greenland, Norway and Russia, and there have been reports that polar bear tracks have been found as far north as the North Pole. The 5,000,000-square-mile range of the polar bear circles the Arctic and contains stretches of open water where seals are easily caught. Polar bears live on the annual Arctic sea ice that provides a platform from which they can hunt. They hunt seals on the sea ice by breaking into seal dens in the sea ice. The dens aren't visible from above,but seeing is less important than smelling to a polar bear -- with their keen sense of smell,polar bears can sense the breathing holes of seals in their dens beneath the snow and ice. As the southern edge of the Arctic ice cap melts in summer, polar bears are stranded on land and spend their summers fasting ,living off body fat stored from hunting in spring and winter. It might come as a surprise that this species faces an uncertain future. Climate change is causing the disappearance of sea ice from which polar bears hunt seals. Sea ice in the Arctic is melting earlier and forming later each year. With about 22,000 polar bears living in the wild,the species is not endangered at the moment, but its future is far from certain. People have reached an agreement that controls the hunting of polar bears and directs each nation to protect their habitats, but it does not protect the bears against the biggest man-made threat to their survival : global warming. If current warming trends continue, scientists believe that polar bears may disappear within 100 years. Question: Polar bears search for seals mainly through their _ . Options: A: eyes B: ears C: noses D: necks
