The health of millions could be at risk because medicinal plants are being used up.These plants are used to make traditional medicine,including drugs to fight cancer."The loss of medicinal plants is a quiet disaster,"says Sara Oldfield,secretary general of the NGO Botanic Gardens Conservation International. Most people worldwide (including 80 percent of all Africans)rely on herbal medicines which are got mostly from wild plants.But some 15,000 of the 50,000 medicinal species are under threat of dying out,according to a report from the international conversation group Plantlife.Shortages have been reported in China,India,Kenya,Nepal,Tanzania and Uganda. Overharvesting does the most harm,though pollution and competition from invasive species are both responsible."Businessmen generally harvest medicinal plants,not caring about sustain ability,"the Plantlife report says."Damage is serious partly because they have no idea of it,but it is mainly because such collection is unorganized." Medicinal trees at risk include the Himalayan yew and the African cherry,which are used to treat some cancers. The solution,says the report's author,Alan Hamilton,is to encourage local people to protect these plants.Ten projects studied by Plantlife in India,Pakistan,China,Nepal,Uganda and Kenya showed this method can succeed.In Uganda the project has kept a sustainable supply of lowcost cancer treatments,and in China a public run medicinal plant project has been created for the first time. "Improving health,earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants,"says Hamilton."You have to pay attention to what people are interested in." Ghillean Prance,the former director of the Royal Botanic Gardens at Kew in London,agrees that medicinal plants are in need of protection. "Not nearly enough is being done,"he told New Scientist."We are destroying the very plants that are of most use to us." What is the passage mainly about? A) The function of medicinal plants. B) The importance of traditional medicine. C) More and more people rely on herbal medicines. D) The dangerous situation of medicinal plants and ways of protecting them.

Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes , Thomas would need to inject himself with insulin three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance. After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar , and created diabeticrockstar.com, a free online community for diabetics and their loved ones--a place where over 1,100 people share personal stories, information, and resources. Jason Swencki"s son, Kody, was diagnosed with type diabetes at six. Father and son visit the online children's forums together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone." Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages. These days, Thomas's main focus is his charity, Fight It, which provides medicines and supplies to people--225 to date--who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000--in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean. Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar one of Rockstar's original members. "But Christopher is the only person I know saying people need help now." What can we learn about Fight It? A) It helps the diabetics in financial difficulties. B) It organizes parties for volunteer once a year. C) It offers less expensive medicine to diabetics. D) It owns a well-known medical website.

Ques: The hottest show this summer---"the Voice" just finished on Sunday at the Shanghai Stadium. But the show that had a good start didn't end to everyone's satisfaction. The two and a half hour show dragged on for more than four hours because of the huge amount of advertising, which the audience and residents living nearby could hardly bear. This summer, something hotter than the weather came to Shanghai. That is the Voice of China. The show soon became a cash cow for the organizer as the advertisement prices reached 1.16 million yuan for 15 seconds. And the show has earned more than 100 million yuan up to now in ad income only, But the organizers' bliss was audiences' melancholy. In the final live show on Sunday, about 14 rounds of advertisements were aired, each of which came at a crucial result-announcing moment. Frequently interrupted by advertisements, some live audience members complained that the show wasn't worth its ticket prices of 180 to 1680 yuan. The planned two and a half hour show went two hours overtime because of the advertising. This annoyed audience members, and touched the nerves of residents living near the site. Someone called the police, and the show is now facing punishment for going over-time and disturbing residents late at night. Why didn't "the Voice" make audience satisfied? A) Because it had a good start but it failed to attract audience' attention in the end. B) Because it had a good start but it failed to make audience satisfied. C) Because it increased by one and a half hour and audience couldbear it. D) Because it was full of so many advisements that audience can't tolerate it.
Ans: D
Federal regulators Wednesday approved a plan to create a nationwide emergence alert system using text messages delivered to cell phones. Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates more than 48 billion text messages are sent each month. The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation's emergency alert system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. "The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan. Participation in the alert system by carriers--telecommunications companies is voluntary, but it has received solid support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three different types of messages, according to the rules. The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction emergencies, or so-called Amber Alerts. The service could be in place by 2014. What is the purpose of the approved plan? A) To warn people of emergencies via messages. B) To popularize the use of cell phones. C) To estimate the monthly number of messages. D) To promote the wireless industry.
