（二）某土地估价机构于2006年10月下旬接到一宗土地价格评估的委托，估价基准日确定在当年10月31日。评估对象位于华南K城市的S湖边，面积500m2，是委托方于2000年10月通过拍卖方式购得的土地，使用期限50年。目前该地块内有一座900m2砖混结构的写字楼，建于2002年10月。写字楼现用于出租，每月租金收入3万元。市场调查显示，该类房屋耐用年限为55年，残值率为2%，当时建筑物综合造价为2000元/m2，目前重置价格为2500元/m2。该写字楼的利用率为90%。当地同类写字楼出租正常空置率为10%，租金一般为每月50元/建筑m2，每年需支付的总费用约80元/建筑m2。假定土地还原率和房屋卒原率分别为7%和8%。根据上述情况，计算并回答56～60题。 假定该写字楼按照自然折旧，则年折旧为（）元。
Passage Four Diego Chiapello, legally blind since birth, isn’t one of Italy’s famous "mama’s boys" who live with their parents into adulthood. The 27-year-old lives alone in Milan, works as a network administrator, loves diving and dreams of sailing across the Atlantic with a sight-impaired (有视力障碍的) crew. Obviously, he’s not your average disabled person--but especially so in Italy. The country has more barriers to integration than almost anywhere else on the continent. Among European countries, Italy ranks third from the bottom in accessibility for the disabled, ahead of only Greece and Portugal. People who use wheelchairs, especially, find it difficult to navigate the country’s cobblestone (鹅卵石) streets, ride buses or visit restaurants, shops and museums. Less than a quarter of Italy’s disabled hold jobs compared with 47 percent for Europe. But the biggest obstacle for the country’s physically challenged may, in fact, be the fabled Italian family. Because of the social defect that still attaches to disabilities, "they tend to keep disabled people at home and out of public view," explains Giovanni Marri, head of an employment training center in Milan that caters to the handicapped. Thus while 15 percent of the country’s families include a disabled person, according to surveys, only 2 percent of Italians report going to school with a disabled person and only 4 percent work with one. Italians are beginning to recognize the problem. Over the past decade, the government has passed laws targeting everything from workplace discrimination to accessibility requirements. A recent study by the European Union found that 85 percent of Italians admit that public transportation and infrastructure (基础设施) are inadequate for the handicapped, and 97 percent say action is needed. But the biggest barrier is psychological. "Italian companies are afraid of hiring disabled people," says Chiapello. The only way to alter that, he says, is for Italy’s disabled to do ’what he did--get out of the house and demand change. What is the passage mainly about

Passage Five What produces a waterproof super glue, acts like a vacuum cleaner, and even teaches scientists about gene repair The humble little shellfish known as the mussel (贻贝)。 Mussels are found worldwide. Some live in the sea. Others inhabit freshwater streams and lakes. When you try to move a mussel from a rock, you will discover what an incredibly firm grip it has- a necessity if the mussel is to resist the sharp grab of a hungry seabird or the pounding waves of the sea. How does it manage to cling so tight When it choose a place to set up home, it pokes its tongue-shaped foot out of its shell and presses it against a solid surface. Special glands give off a fluid mixture of proteins into a channel that runs the length of the foot. The liquid quickly hardens into a fine, elastic thread about an inch long. Then a tiny pad-like structure at the end of this thread gives off some natural glue-like substance, the mussel lifts its foot, and anchor line number one is complete. These strategically placed threads form a bundle, which ties the mussel to its new home in much the same way that ropes hold down a tent. The whole procedure takes only three or four minutes. Imagine having a very strong glue that is non-toxic and so flexible that it can penetrate the tiniest holes and corners, sticking to any surface, even under water. Shipbuilders would welcome it for repairing vessels without the expense of dry-docking them. Auto-body workers would like a really waterproof paint that keeps the rust out. Surgeons would value a safe glue to join broken bones and to close wounds... The list of possible uses appears endless. However, scientists are not thinking of using the mussels themselves to produce this super glue. It would take some l0.000 shellfish to make just one gram of glue. So collection enough mussels to supply the world’s demand for super glue would wipe out the mussel population, many species of which are already endangered. Instead, American researchers have isolated and cloned the genes for five mussel glue proteins, and they are about to mass-produce them in the laboratory. However, the mussel is still one jump ahead. Only the mussel instinctively knows the exact blend of proteins needed for each kind of surface. Molecular biologist Frank Roberto has asked admiringly: "How are you ever going to imitate that" A mussel grips a hard surface very firmly to
