    　　The Italian island of Sardinia recently lost its oldest person．Family members say Antonio Todde died in his sleep early this month．Mr Todde was 112 years old．He was less than three weeks away from his 113th birthday．Record-keeping experts say he was the world’s oldest man．

    　　His long life and that of other very old Sardinians are the subjects of a scientific project(项目)called Akea．Luca Deiana of Sassari University is directing(指导)the study．He says the name Akea comes from a traditional greeting(问候)on Sardinia．It means “health and life for 100 years．” Professor Deiana and his team started to collect information for the study in 1997．They identified(确定))more than 220 Sardinians who were centenarians －－100 years old or older．His team needed three documents to make sure a person’s age．They were a government(政府)birth record, a church record and a statement(声明)by a close family member．

    　　The Akea study has produced two major findings．The first is Sardinia’s extremely high number of centenarians．The island has about 135 centenarians for every one million people．In other Western countries, the average(平均数)is about seventy-five centenarians for every one million people．The second major finding is an unusual rate(率)of female(女性)to male(男性)centenarians．Sardinia has two women centenarians for every male centenarian．In central Sardinia there are the same numbers of female and male centenarians．

    　　Studies in other parts of the world have shown a much higher percentage(百分比)of female centenarians．The Akea study collected information about the health and food of about 140 of the centenarians．About ninety percent of those in the study also agreed to provide blood(血)for scientific testing．The study team hopes to identify genetic(基因)material in the blood that can be linked to successful aging．Study leaders say there is no single reason why people on Sardinia live so long．They believe the answer is a combination(组合)of genetic and environmental conditions(条件)．

    判断下列句子是否符合短文内容，符合的用“T”表示，不符合的用“F”表示

    　　In September 1991, two German mountaineers were climbing in the Italian Alps(阿尔卑斯山)when they saw something lying in the ice．They were surprised when they realized that it was the body of a man．The two Germans guessed that the man had been another mountaineer．Many climbers had been killed in the Alps over the past 200 years, and sometimes their dead bodies were found after a long time．

    　　When the two men got back to the nearest town, they reported what they had seen and the body was recovered．When doctors examined it to try to identify the man, they discovered something surprising．The man was not a modern mountaineer, but a Bronze Age(青铜器时代)traveler who lived more than 5,000 years before．He had died high up in the mountains and the freezing temperatures and thick ice kept his body perfect for thousands of years．

    　　Scientists gave the Bronze Age man the name Otze and began to study him in detail．He was 1.57 meters tall and weighed 55 kilos when he was alive．When the Germans found the body, it was lying down near some rocks with the right arm across the face．Scientists guessed that Otze had died while trying to take shelter among the rocks．Perhaps he was covering his face with his arm to protect the snow and wind．

    　　The ice had not only kept Otze's body, but also the things he had been carrying with him．These gave the scientists exciting new information about the life thousands of years ago．Otze's clothes, shoes and hat were made of animal skins, and his shoes were filled with grass to keep his feet warm．Scientists were even able to say what Otze had eaten for his last meal by examining the frozen remains in his stomach．

    (1)

    Two German mountaineers saw a wounded mountaineer lying in the ice．

    (　　)

    (2)

    A lot of mountaineers were killed by others when they were climbing the Alps．

    (3)

    People living in Bronze Age also liked climbing mountains．

    (　　)

    (4)

    The body was perfect for thousands of years because of freezing temperatures and thick ice．

    (　　)

    (5)

    One of the reasons for scientists to study Otze is to know more about the life of people thousands of years ago．

    (　　)

    (6)

    Otze's shoes were so big for him that he filled them with grass．

    (　　)

    (7)

    Scientists knew what kind of person Otze was by studying the frozen remains in his stomach．

    (　　)

    　　Look closely at your hands．Are they clean? It doesn't matter how many times you wash your hands, tiny microbes(微生物)still stay on them．But don't worry．Most microbes don't harm you．

    　　Now scientists say the microbes on our hands could be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹)could be used to indentify the criminal．

    　　When you work on a computer you leave the microbes from your hands on the keyboard．The scientists can easily tell the owner of the keyboard by looking at the microbes on it．Even if you don't leave your fingerprints behind, your microbes may give you away．

    　　Noah Fierer, a scientist, says．"You can only clean a fingerprint, but you can't sterilize(使无菌)a surface just by wiping(擦)it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool．
