    阅读理解：阅读下面的短文，然后根据短文内容选择最佳答案。

    　　Comets(彗星)are parts of our solar system．Like the planets, they go around the sun．

    　　But comets are not made of solid rocks like planets．A comet is a ball of dust, stones, and ice．Many people call comets dirty snowballs．

    　　The “snowball” may be only a few miles across．But when the sun heats the “snowball, ” much of it is changed to gases．The gases spread out and form the comet's head, which may be thousands of miles across．

    　　A comet moves fast in its trip around the sun．But when we see it, the comet does not seem to move．That's because it is so far away．The moon moves fast, but when you look at it, you can't see any motion(运动)．That's because the moon is far away．

    　　Each year astronomers(天文学家)discover new comets．Some of them are seen only once．They make one trip around the sun and then go away out into space．The sun's gravity cannot hold them．

    　　Other comets, like Halley, keep returning．They have been captured by the sun．Halley's earliest visit was probably 3, 000 years ago．It may keep returning for another 3, 000 years．

    　　But every time a comet goes around the sun, the comet loses part of itself．Gases and dust are pulled out of the comet．That's why Halley is now dimmer(暗淡的)than it used to be．Next time it visits us, in 2062, it may be even dimmer．Each visit it may get dimmer and dimmer, until it finally disappears．

    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)

    (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．
