问题     Every human being has a【C1】______ arrangement of the skin of his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of fingerprints and discovered that【C2】______ exactly similar pattern is passed from parents to children, though nobody knows why this is the case.
    The ridge structure on a person’s fingers does not change with growth and is not affected by【C3】______ injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which【C4】______ a reproduction of the original pattern. It is only when the inner skin is injured【C5】______ the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints,【C6】______ this is a dangerous and rare step to take.
    Finger-prints can be made very easily with printer’s ink. They can be recorded easily. With special methods,【C7】______ can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal【C8】______ . A suspected man may【C9】______ a charge but this may be in vain. His finger-prints can prove who he is even if his【C10】______ has been changed by age or accident.
【C7】
选项 A、reproduction
B、identification
C、demonstration
D、discovery
答案B
解析 A项reproduction意为"复制"，B项identificat：ion意为"鉴定，鉴别"，C项de—monstration意为"证明，示范"，D项discovery意为"发现"。上文提到，指纹可以很容易地通过油墨留下，因此A项用在本句显然不合适，正确答案应为B。本句的意思是：运用特殊的方法可以在很短的时间里进行成功的鉴别。C、D两项与原句意思不符，故也不能选用。
