    At the age of twelve, the human body is at its most vigorous. It has【C1】______ to reach its full size and strength, and its owner his or her full intelligence: but at this age the【C2】______ of death is least. Earlier, we were infants and young children, and consequently more【C3】______: later, we shall【C4】______ a progressive loss of our vigour and resistance which, though imperceptible at first, will finally become so【C5】______ that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This【C6】______ in vigour with the passing of time is called ageing.
    Most animals we commonly observe in fact age as we【C7】______, if given the chance to live long enough: and mechanical systems like a wound watch, or the sun, will run out of energy someday. But these are not【C8】______to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch,【C9】______, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself—it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves—well enough, at least, to【C10】______ all but the most instantly fatal illnesses and accidents. Between twelve and eighty we gradually lose this power: an illness which at twelve would knock us over, at eighty can knock us out.
【C8】
选项
答案F
解析 根据上文可知these指的是“大多数动物的衰老过程和机械装置或太阳的能源耗尽过程”，由下文提到的人的自我修复功能可知，这些与人衰老的过程并不一样，备选项中analogous符合句意，be analogous to意为“相似的，类似的”。
