The incidence of hip fractures not only increases after age 50 but doubles every five to six years as the risk of falling increases. Slipping and tumbling are not the only causes of hip fractures; weakened bones sometimes break spontaneously. But falling is the major cause, representing 90% of all hip fractures. ThesE... ...

TEXT D'Museum' is a slippery worD.It first meant (in Greek) anything consecrated to the Muses: a hill, a shrine, a garden, a festival or even a textbook. Both Plato's Academy and Aristotle's Lyceum had a mouseion, a muses' shrinE.Although the Greeks already collected detached works of art, many temples - notably that of Hera at Olympia (before which the Olympic flame is still lit) - had collections of objects, some of which were works of art by well-known masters, while paintings and sculptures in the Alexandrian Museum were incidental to its main purposE.The Romans also collected and exhibited art from disbanded temples, as well as mineral specimens, exotic plants, animals; and they plundered sculptures and paintings (mostly Greek) for exhibition. Meanwhile, the Greek word had slipped into Latin by transliteration (though not to signify picture galleries, which were called pinacothecae) and museum still more or less meant 'Muses' shrine'.The inspirational collections of precious and semi-precious objects were kept in larger churches and monasteries - which focused on the gold-enshrined, bejewelled relics of saints and martyrs. Princes, and later merchants, had similar collections, which became the deposits of natural curiosities: large lumps of amber or coral, irregular pearls, unicorn horns, ostrich eggs, fossil bones and so on. They also included coins and gems - often antique engraved ones - as well as, increasingly, paintings and sculptures. As they multiplied and expanded, to supplement them, the skill of the fakers grew increasingly refineD.25.The sentence 'Museum is a slippery word' in the first paragraph means thatA.the meaning of the word didn't change until after the 15th century.B.the meaning of the word had changed over the years.C.the Greeks held different concepts from the Romans.D.princes and merchants added paintings to their collections.

Renewable Energy Sources Today petroleum(石油)provides around 40% of the world’s energy needs,mostly fuelling automobiles.Coal is still used,mostly in power stations,to cover one-quarter of our energy needs,but it is the least efficient,unhealthiest and most environmentally damaging fossil fuel(矿物燃料).Natural gas reserves could fill some of the gap from oil,but reserves of that will not last into the 22nd century either.Most experts predict we will exhaust easily accessible reserves within 50 years.Less-polluting renewable energy sources offer a more practical long-term energy solution.“Renewable”refers to the fact that these resources are not used faster than they can be replaceD.Hydroelectric(水力发电的)power is now the most common form. of renewable energy,supplying around 20% of world electricity.China’s Three Gorges Dam is the largest ever.At five times the size of the US’s Hoover Dam,its 26 turbines(涡轮机)will generate the equivalent energy of 18 coal-fired power stations.It will satisfy 3% of China’s entire electricity demanD.In 2003,the first commercial power station to use tidal(潮汐的)currents in the open sea opened in Norway.It is designed like windmill(风车),but others take the form. of turbines.As prices fall,wind power has become the fastest growing type of electricity generation-quadrupling(翻两番)worldwide between 1999 and 2005.Modern wind farms consist of turbines that generate electricity.Though it will be more expensive,there is more than enough wind to provide the world’s entire energy needs.Wind farms come in onshore and offshore forms.They can often end up at spots of natural beauty,and are often unpopular with residents.And turbines are not totally harmless-they can interfere with radar,alter climate and kill sea birds.Scotland is building Europe’s largest wind farm,which will power 200,000 homes.The UK’s goal is to generate one-fifth of power from renewable sources,mainly wind,by 2020.But this may cause problems,because wind is unreliablE.第11题：According to the passage,which of the following is the most polluting energy resource?A.Petroleum.B.Coal.C.Natural gasD.Water.
