Q: Chinese female scientist Tu Youyou won the 2015 Nobel Prize in medicine on October 5 for her discoveries concerning a novel treatment against Malaria . This is the first Nobel Prize given to a Chinese scientist for work carried out within ChinA. Tu shared the prize with Irish-born William Campbell and Satoshi Omura of Japan, who were honored for their revolutionary anti-roundworm treatment. 84-year-old Tu is awarded this prize for her contribution to cutting the death rate of malaria, reducing patients' suffering and promoting mankind's health. Although she received several medical awards in the past, the 2015 Nobel Prize is definitely the most privilege reward that recognizes Tu's dedication and perseverance in discovering artemisinin , the key drug that battles malaria-friendly parasites . However, her route to the honor has been anything but traditional. She won the Nobel Prize for medicine, but she doesn't have a medical degree or a Phd. In China, she is even being called the "three-noes" winner: no medical degree, no doctorate, and she's never worked overseas. No wonder her success has stirred China's national pride and helped promote confidence of native Chinese scientists. The fact that Tu has none of these three backgrounds reminds us that science should be more accessible to all. One shall be able to become a scientist no matter what kind of background he or she comes from, as long as one dives into scientific research. There have been discussions on people who really love science but are never able to achieve much during their whole life. Their contributions can never be ignored. They work so hard to prove the wrong way so that the future researchers will be closer to the right one. As the first Chinese mainland Nobel Prize Winner of natural science award, Tu's record-breaking winning also serves as a reminder to those who are too eager for instant success. Science is never about instant success. Tu spent decades on scientific research before its value is officially acknowledged. There is no way to... It can be concluded from the text that _ . A) Tu worked home and abroad to conduct her research B) Tu got the Nobel Prize for her anti-roundworm treatment C) The Nobel Prize is the first award to recognize her work D) Her discovery of artemisinin has helped to cut Malaria death rate

Q: Bananas are one of the world' s most important food crops. They are also one of the most valuable exports. Bananas do not grow from seeds. Instead, they grow from existing plants. Bananas are threatened by disease because all the plants on a farm are copies of each other. They all share the same genetic weaknesses. For example, the Cavendish banana is most popular in North American and European markets. However,some kinds of fungus organisms easily infect the Cavendish. Black Sigatoka disease affects the leaves of Cavendish banana plants. The disease is controlled on large farms by putting chemicals on the plant' s leaves. Farmers put anti-fungal chemicals on their crops up to once a week. Another fungal disease is more serious. Panama disease attacks the roots of the banana plant. There is no chemical treatment for this disease. Infected plants must be destroyed. Panama disease has affected crops in Southeast Asia, Australia and South Africa. There is concern that it may spread to bananas grown in the Americas. This could threaten an important export product for Central and South America. The International Network for the Improvement of Banana and Plantain supports research on bananas. The group has headquarters in France and other offices in the major banana-growing areas of the world. The group says that more research must be done to develop improved kinds of bananas. The group says that fungal diseases mainly affect only one kind of banana. In fact, there are five hundred different kinds of bananas. Food and Agriculture Organization of the United Nations has said that the Cavendish banana represents only 10% of world production. The U.N. agency says farmers should grow different kinds of bananas. This protects against diseases that affect only one kind. Experts warn that disease may cause the Cavendish banana to disappear. This happened earlier to another popular banana because of its genetic weakness against disease. According to the passage, which information is right? A) The Cavendish banana can mainly be imported from North America and Europe. B) Panama disease affects the leaves of Cavendish banana plants. C) The Cavendish banana won't die out in the future. D) The Cavendish banana makes up only one tenth of world production.

Q: More and more pupils are giving teachers presents, but the practice only creates insecurity in parents and staff. I've certainly noticed some pupils being feverishly overgenerous of late. Last year, I received not one bottle of wine but four for helping a disaffected pupil through his GCSEs. By and large, my colleagues report the gifts differing along gender lines. Gentlemen get ties, mugs, booze and, if they're really lucky, tickets to football matches. The ladies are often presented with flowers, jewels, chocolates and so on. When my son was at private school, I noticed there was a real competitiveness between the students about giving presents to teachers, with expensive baskets from fancy stores and huge bouquets being handed out on the last days of term. Since my wife and I only let my son give thank-you cards, it was clear we were not "classy". Now he is at an inner-city primary, we've noticed that this kind of _ seems to have more or less disappeared. For one thing, there isn't that kind of money floating around - but there isn't that kind of competitive culture either. Personally, I think gifts to teachers should be banned beyond the thank-you card: they cause many more problems than they solve, creating insecurity in both parents and staff. Perhaps the recession and the lack of money in people's pockets might be a good excuse for the government to issue some guidelines to schools that gifts shouldn't be accepted by teachers. The gifts that I really value are the cards which say a genuine thank you. I still keep them in a file at home. To solve the problem, the author thinks it's a good way to _ . A) forbid the students to give any gifts to teachers B) create insecurity by giving thank-you cards C) make people have less money in pockets D) issue some guidelines by the government
