After an hour's flight one of the scientists wrote in his book, "Look here for probable metal." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word "Uranium." None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth's surface. They were merely putting to use one of the newest methods of locating minerals in the ground---using trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface. At Watson Bar Creek, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches. If the trees had not indicated that there was gold in the ground, the scientists would not have spent money to pay for digging into the ground. They did dig and found more gold below. They dug deeper. They found large quantities of gold. Question: Scientists went to different regions in order to search for _ . Options: A: gold B: silver C: metals D: minerals

Read the article and select the best answer. Article: Grandma celebrated her fifty-third birthday just weeks before grandpa died of cancer in 1965. Although his passing was very difficult for her, I think their shared struggle to make his life longer taught grandma that good health was not to be taken for granted, and she made up her mind to live the rest of her own life as fully and as long as she could. One day, when she announced to attend lessons at the Fred Astaire Dance Studio in Portland, Oregon, where she lived, we rolled our eyes in embarrassment and helplessly wished she would just stay home and bake cookies as normal grandmothers did. Many years filled with countless dance lessons passed before we learned to appreciate the wonder of having a dancing grandma. I suppose grandma's primary motivation for wanting to learn to dance was social. She had been a shy girl, always very tall and heavy, and had married into grandpa's quiet lifestyle before developing any elegance or confidence in her personal appearance. Dancing, on the other hand, filled her life with flash lights, wonderful parties, beautiful dresses, handsome young dance instructors, and the challenge of learning. Although the weekly dance lessons did not change her ample, two-hundred-pound figure, grandma surprised everyone with energetic performances on the dance floor, which soon gave her as much elegance and confidence as any Miss American competitor. Having taken weekly dance lessons for years, my grandma learned various dances easily and was soon participating in dancing matches all over the Northwest. When I was fourteen, grandma proudly invited me to watch her compete in one of these matches to be held in the grand ballroom of the Red Lion Inn. My attitude was still unenthusiastic at that point, but to make her happy, my mother and I attended the match. As if to prove me wrong, grandma made a wonderful showing in every event she entered. I thought she was truly the queen of the ball during the dance, and my thoughts were shared by the judges a short time later when she was awarded a gold... Question: Normal grandmas usually _ in the author's point of view? Options: A: took dance lessons B: did some exercises at home C: took care of grandchildren at home D: did some housework at home

Read the article and select the best answer. Article: Tu Youyou, the 85-year-old Chinese pharmacologist ,received the Nobel Prize for medicine in Stockholm on December 10,2015. Tu is the first Chinese Nobel winner in physiology or medicine. Also, in 2011, she became the first Chinese person to receive the US-based Lasker Award for clinical medicine. Based on a fourth-century Traditional Chinese Medicine (TCM) text, together with her team, she managed to get artemisinin from sweet wormwood through trial and error and developed an important drug that has significantly reduced death rates among patients suffering from _ . Tu delivered a speech titled Artemisinin is a Gift from TCM to the World. She has urged more research into the benefits of traditional Chinese medicine and called for joint efforts worldwide to fight against malaria and develop more potential uses for TCM, which she called a "great treasure" with thousands of years' history and empirical knowledge. She said that by combining TCM with modem scientific technologies, "more potential can be discovered in searching for new drugs " . According to the WHO, more than 240 million people in sub-Saharan Africa have benefited from artemisinin, and more than l. 5 million lives are estimated to have been saved since 2000 thanks to the drug. Apart from its contribution to the global fight against malaria, TCM played a vital role in the deadly outbreak of SARS across China in 2003. Besides treating viruses, TCM has been most effective in diagnosing diseases, cultivating fitness, treating difficult multisource illnesses, and using nonmedical methods such as acupuncture and breathing exercises. However, TCM, which is based on a set of beliefs about human biology, is seldom understood or accepted by the West. Tu's success will bring more recognition and respect for TCM, experts say. The Western world should learn to appreciate the value of the treasures of TCM, which will lead to more basic scientific research into ancient TCM texts and ways to explore research findings worldwide. Question: What can we learn from the passage? Options: A: This success may encourage Easterners to learn more about Chinese medicine. B: Nothing remains to be done in researching into TCM theories and texts. C: More research into the value of TCM should be carried out worldwide. D: TCM only contributes to the fight against malaria and SARS in China.
