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: Which of the following is TRUE according to the passage? Yes or no, is the answer "About 30% of medicinal species are at risk of dying out."?
No

Article: As the capital of China's Shaanxi Province, Xi'an's long history was properly summed up by our English-speaking guide: "If Xi'an is the grandmother of cities, Beijing is a youth and Shanghai is just a baby in the womb. " However, it was not until 1974, following the chance discovery of the Army of Terracotta Warriors by well-digging farmers, that Xi'an was once again pushed onto the international map. Three decades later, the local government is pouring funds into the tourism sector. Ancient monuments and museums are being restored, and various copies of Buddhist and Tang heritage are being constructed to help Chinese tourists rediscover their national heritage. One of those ancient monuments is the Big Wild Goose Pagoda-Xi'an's most sacred monument-which was built in 652 by the monk Xuanzang ,who travelled across India for 18 years and returned with a precious collection of Buddhist sacred texts. In 1966,the Red Guards burnt the pagoda's scriptures, silk wall hangings and other relics in a bonfire that raged all night. But that destruction has largely been forgotten as tourists flock to the newly restored pagoda. The only original remainders-the empty shell of the seven-storey pagoda-light up at night, standing out in the city's skyline. Xi'an is also displaying the glories of the ancient Tang Dynasty, with a 165-acre Tang Paradise Theme Park that is visited by flocks of tourist groups. Although every bit of this Tang heritage is recreated, it is artistically pleasing, landscaped with ponds and lakes, classical gardens, bridges, palaces and pavilions. Explore the vast area on a golf cart, hopping on and off to see shortened operas from the Tang Dynasty days, laser shows on the lake, highly structured man-made waterfalls, as well as murals and statues of historical figures ,philosophers and poets. A 36km drive northeast takes you to Xi'an's most famous attraction, the Army of Terracotta Warriors. They were made to order in 221BC by the first emperor of China, Qin Shi Huangdi, who used the forced labour of... Question: From the passage we can learn that a large sum of money of the local government in Xi'an is being ploughed into _ Yes or no, is the answer "tourism industry"?

Article: Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained. Question: It is _ for a criminal to deny his crime when finger-prints are used to identify him. Yes or no, is the answer "useless"?
No
