Qi Baishi (1863~1957) is one of the best-known contemporary Chinese artists. His life shows he achieved success by combining talent with hard work. He was born in a peasant family. At 11 he was sent to learn carpentry . Through his work he got to know some local scholars. One of them, Hu Shenyuan, offered to teach his painting and poetry. During this period he earned his living by painting portraits and selling his works. Gradually he developed a reputation as an artist as well as a carpenter. In those years he devoted himself to poetry, calligraphy , and seal-carving. Although he admitted he was a versatile artist, his own criteria of his successes placed poetry first, seal-carving second, calligraphy third, and painting last. From 1902 to 1916, Qi toured the country five times, and he left his footmarks in many cities, such as Beijing and Hongkong. The trips broadened his vision and changed his style. In 1917 he settled down in Beijing, where he met many artists and scholars, and made friends with Chen Shizeng. Chen advised him not to _ early masters and to form his own style. Through long years of practice, Qi Baishi evolved a distinctive personal style. The subjects of his painting were wide and various, and the flowers, birds, fish, prawns , and insects he painted are most admired by his public. To improve his technique of painting prawns, he raised some at home and frequently observed their movements. He wrote in his diary about how he had changed his method of painting prawns: "At first my prawns owned a reasonable similarity, then they became even more realistic, and finally light and dark color1s became properly contrasted. These are the three changes." Qi Baishi was able to portray the same object in either the xieyior thegongbistyle. When he painted a dragonfly in a detailed manner, he even drew the veins in its wings. When he adopted a , free style, he used only a few dry, expressive strokes to form it. What is fascinating about his work is that in some pictures both methods are used. Which of the following is Qi's fascination about his works? A) He could draw many animals in a painting. B) He drew the veins in a dragonfly's wings. C) He could draw different colours of prawns. D) He could use the xieyiand thegongbistyles in a painting.

Farm-raised pigs are dirty, smelly animals that get no respect. They're also an environmental hazard. Their manure contains phosphorus ,which, when it rains, runs off into lakes and rivers, consuming oxygen, killing fish, stimulating algae overgrowth and emitting greenhouse gases. Doing away with the pig is not an option. Pigs provide more dietary protein, more cheaply, to more people than any other animal. Northern Europe still maintains the highest pig-to-human ratio in the world (2-1 in Denmark), but East Asia is catching up. During the 1990s, pork production doubled in Vietnam and grew by 70 percent in China--along densely populated coastlines, pig density exceeds 100 animals per square kilometer. The resulting pollution is "threatening fragile coastal marine habitats including mangroves ,coral reefs and sea grasses ,"according to a report released in February by the Food and Agriculture Organization of the United Nations. As it turns out, there is a solution to the pig problem, but it requires a change of mind-set among environmentalists and the public. Two Canadian scientists have created a pig whose manure doesn't contain very much phosphorus at all. If this variety of pig were adopted widely, It could greatly reduce a major source of pollution. But the Enviropig, as they call it, is the product of genetic modification--which is anathema to many Westerners. The Enviropig is one of many new technologies that are putting environmentalists and organic-food supporters in _ : should they remain categorically opposed to genetically modified (GM)foods even at the expense of the environment? Elsewhere, trees grown for paper could be made amenable to much more efficient processing, reducing both energy usage and toxic chemical bleach in waste water from paper mills. The most significant GM applications will be ones that help lessen the problem of agriculture , which accounts for 38percent of the world's landmass and is crowding out natural ecosystems and species habitats. Chances are, farmers will... The negative influence brought by the traditional agriculture is _ -. A) more living space occupation B) more crop improvement C) more food production D) more chemical application

Q: Dogs have long been used to find explosives and drugs.Now,a new study shows that man's best friend can also help to find lung and breast cancer,researchers report in integrative Cancer Therapies.The findings show that trained ordinary household dogs can detect early--stage lung and breast cancers by smelling the breath samples of patients. Researchers have found that cancer cells send out molecules different from those of healthy ones,and that might be sensed by smell by the highly sensitive dog's nose. For the study,five dogs were trained by a professional instructor to respond differently to breath samples of healthy and cancer patients."The dogs learned to sit or lie down in front of cancer patient samples and to ignore control samples through the method of food reward," McCulloch explained. After a period of training,researchers tested the animals'ability to distinguish cancer patients from controls.The animals were given breath samples from 55 patients with lung cancer,3 1 with breast cancer and 83 healthy controls who were not included in the original training period. McCulloch's group found that the dogs were able to correctly distinguish the breath samples of cancer patients from those of the control subjects in about 90 percent of the cases.The dogs were also able to detecting early-stage lung and breast cancers. "These results show that there is hope for early detection,"McCulloch said.The re-searches are planning to conduct further studies on the breath composition of cancer patients to possibly design an electronic device that can do the dogs'job."A dog's nose is so powerful it can detect odors 10 000 to 100 000 times better than a human nose can.I hope people will be interested in doing this research,"McCulloch added,"It shows that there is definitely something out there." We can infer from the passage that_. A) dogs can smell signs of other cancers except the above two kinds B) the final goal of the researchers is to design an electronic dog to detect cancer C) dogs can detect odors 10 000 to 100 000 times better than humans can D) dogs will soon be widely used to smell signs of cancers in hospitals
