Article: 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." Question: What is the passage mainly about? Options: 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.

Read the article and select the best answer. Article: It is a familiar scene these days: employees taking newly laidoff coworkers out for a drink for comfort. But which side deserves sympathy more, the jobless or the still employed? On March 6, researchers at a conference at the University of Cambridge heard data suggesting it's the latter. Brendan Burchell, a Cambridge sociologist, presented his analysis based on various surveys conducted across Europe. The data suggest that employed people who feel insecure in their jobs show similar levels of anxiety and depression as those who are unemployed. Although a newly jobless person's mental health may "bottom out" after about six months, and then even begin to improve,the mental state of people who are continuously worried about losing their job "just continues to get worse and worse," Burchell says. Evolutionary psychologists support this theory by arguing that human beings feel more stress during times of insecurity because they sense an immediate but invisible threat. Patients have been known to experience higher levels of anxiety, for example, while waiting for examination results than knowing what they are suffering from -- even if the result is cancer. It's better to get the bad news and start doing something about it rather than wait with anxiety. When the uncertainty continues, people stay in a nonstop "fight or flight" response, which leads to damaging stress. But not every employee in insecure industries has such a discouraging view, Burchell says. In general, women get on better. While reporting higher levels of anxiety than men when directly questioned, women scored lower in stress on the GHQ 12, even when they had a job they felt insecure about losing. As Burchell explains, "For women, most studies show that any job -- it doesn't matter whether it is secure or insecure -- gives psychological improvement over unemployment." Burchell supposes that the difference in men is that they tend to feel pressure not only to be employed, but also to be the primary breadwinner, and that more of a man's selfworth... Question: Why do researchers think the still employed deserve sympathy more? Options: A: They have to do more work since then. B: They have no chance to find better jobs. C: They have to work with inexperienced workers. D: They constantly worry about losing their job.
