    6．For years，scientists have argued over what killed the great Austrian composer Wolfgang Amadeus Mozart （1756-1791）．The various accounts of his final days suggest that he might have died from strep or trichinosis or rheumatic fever or renal disease or"'Now two researchers have put forth another diagnosis：a vitamin deficiency．
    Uncertainty clouds Mozart's death because physicians of the time did not know how to diagnose most illness．No autopsy of his body was performed either．
    Like many people of the time，Mozart was often sick．He suffered from smallpox，typhoid fever，and several respiratory infections．Illness tended to strike him between mid-October and mid-May，says William Grant，a retired U．S．atmospheric scientist who is a member of the Sunlight，Nutrition and Health Research Center．Grant and Stefan Pilz，an Austrian researcher，studied more than 80references to Mozart's health in medical literature．
    Mozart's poorer health between October and May may have dated from a vitamin D deficiency． says Grant．Vitamin D is the"sunshine vitamin"； the human body makes it when exposed to strong sunlight．People who live at higher latitudes don't get that exposure between late autumn and early spring．
    Vitamin D aids in the absorption of calcium，a mineral that help build strong skeletons．Not enough Vitamin D can lead to tickets，a disorder marked by soft，weak bone．
    Mozart's habits may have made his D deficit worse，says Grant．'The composer was a night owl who often slept through the day，thereby depriving （使丧失） himself of even more sunshine．"Mozart died on December 5，1791，two to three months into the vitamin D winter，"wrote Grant and Pilz in the journal Medical Problems of Performing Artists．Vitamin D is also involved in the operation of more than 200genes．Low vitamin D levels are linked to high blood pressure，heart disease，and many cancers．
    Vitamin D deficiencies still exist among residents of the higher latitudes，say scientists．We now know what people in Mozart's day did not know，however．Milk，eggs，and oily fish are good sources of Vitamin D．So is 10to 20minutes of unprotected exposure to the sun every Summer day．

    46．It is certain thatC．
    A．Mozart died from renal disease
    B．Many people in Mozart's time suffered from smallpox
    C．Mozart was often ill between autumn and the next spring
    D．William Grant knows little about Mozart'health
    47．The underlined word"deficiency"in the fourth paragraph most probably means"B"．
    A．the quality of doing something well
    B．a lack of something that is necessary
    C．a weakness or fault in something
    D．a choice or judgment that you make after a discussion
    48．Which of the following is NOT TRUE about Mozart？D．
    A．'Physicians of Mozart's day didn't know much about his illness
    B．Mozart lived at a high latitude
    C．Mozart often worked at night and slept during the daytime
    D．Mozart was 45years old when he died
    49．What is the text mainly about？B．
    A．Stories about Mozart
    B．A probable death cause of the great Austrian composer
    C．The importance of Vitamin D
    D．Good sources of Vitamin D．

    4．Do you have any skiing equipment you are no longer need？A ski school in the far north of India could put it to good use．
    In March we published a photostory about the extraordinary Zsnskar region in northern India，which is cut off from the outside wodd for more than seven months of the year，and only accessible via a frozen river．We also included information about the limited use of skiing in the region and the recent creation of the Zanskar Ski School：
    "Despite the difficulties of travelling through the region when the snow comes，skiing hash't traditionally been used as a means of transport by the locals，largely because trees don't grow here，so there is little in the way of raw materials from which to make skis．In 1995，a group of British scientists in the region noticed the lack of skis and one of them returned to set up the Zanskar Ski School in Padam．The school provides lessons for a small fee and rents out donated skis to the local people．Among the benefits that the school hopes to bring are improved education-children often find it difficult to get to school through the deep snow-and the possibility of offering ski tours to tourists in the future．So far，more than 300 local people have received training，and local doctors and policemen regularly borrow skis．"
    But，what we weren't able to include in the article is that the ski school is always on the look out for old skiing equipment-particularly of a size suitable for children-and，I thought．now the European ski season is drawing to a close，there might be a few of you out there who have some old equipment you'd like to see go to a good home．If that's the ease you can get in touch with the school via their website www．zanskarskischooL．org．
    66．What's the purpose in writing the text？A
    A．To ask people to give away their skis to the school
    B．To attract more tourists to the area
    C．To appeal to more locals to attend the school
    D．To raise money to develop this area
    67．The local people don't use skiing to go about becauseC．
    A．it is against the local custom
    B．trees are in the way of the skiing route
    C．they don't have the wood to make skis
    D．it is dangerous to go skiing in this region
    68．The Zanskar Ski SchoolB．
    A．has donated money to the local community
    B．makes it easier for the students to attend school
    C．provides special training to the tourists
    D．has borrowed many skis from Europe
    69．Who would be the most helpful to the school now？C
    A．Locals in Zanskar region．           B．Students in the Zanskar Ski School．
    C．People having old skiing equipment．  D．Tavellers enjoying skiing．
    70．What can be the best title for the text？D
    A．An extraordinary region in India    B．The Zanskar Ski School
    C．A good means of transport         D．A home for old skis．
