Question

【題目】Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

The ridge（脊?fàn)睿﹕tructure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but 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, identification 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 case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.

When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

【解析】

試題分析：這篇文章告訴我們每一個(gè)人的指紋都是不一樣的，并且指紋的形狀是不會(huì)隨著年齡的增長以及受傷而改變的，除非改變它的內(nèi)部形狀。因此在破案時(shí)，一旦罪犯的指紋被發(fā)現(xiàn)，他的身份就會(huì)被暴露。

【1】細(xì)節(jié)題。由第一段中的Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children句意為科學(xué)家以及專家證實(shí)了指紋的獨(dú)特性，并且發(fā)現(xiàn)沒有確切的相似的圖案是由父母遺傳給孩子的，可以推斷出人類指紋的圖案是不同于任何其他人的。故選D。

【2】推斷題。由第二段中的The ridge（脊?fàn)睿﹕tructure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. 句意為人們指紋的脊?fàn)罱Y(jié)構(gòu)不會(huì)隨著年齡的增長以及表面的受傷而改變的。燙傷，切傷以及對于表面皮膚的其他傷害會(huì)及時(shí)的被另一塊皮膚替代，這塊皮膚是原來皮膚的原始圖案的復(fù)制品，可以推斷出當(dāng)手受傷了，它恢復(fù)之后的皮膚圖案是沒有變化的。故選C。

【3】細(xì)節(jié)題。由第二段中的It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. 句意為只有當(dāng)內(nèi)部皮膚受損時(shí)，這種一致性才會(huì)被破壞。一些罪犯利用這個(gè)事實(shí)，移除自己的指紋，但是這是很危險(xiǎn)，很稀少的做法。可以推斷出罪犯通過傷害自己的內(nèi)部皮膚來改變自己的指紋。故選B。

【4】推斷題。由第三段中的Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case.句意為由于這個(gè)系統(tǒng)的簡單性以及經(jīng)濟(jì)性，改變指紋成為解決犯罪案件中經(jīng)常使用的一種方法，可以推斷出這樣做的原因是這種方法既簡單又不貴，故選B。

【5】推斷題。由最后一段中的Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained句意為盡管有些標(biāo)記是不完整的，但是如果獲得了四分之一的指紋，那么這是有可能得到確認(rèn)的，可以推斷出當(dāng)指紋被用來指控罪犯時(shí)，罪犯否認(rèn)是沒有用的，故選D。
