Question

1. 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 （隆起） structure 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．2. 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 by recorded easily．3. 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．4.

When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye.

5. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

A．Special techniques are used to "develop" them.

B．A fingerprint is an impression of the friction ridges of all part of the finger.

C．It is only when the inner skin is injured that the arrangement will be destroyed.

D．With special methods, identification can be achieved successfully within a short time.

E．A latent print is the chance reproduction of the friction ridges deposited on the surface of an item.

F．His finger-prints can prove who he is even if his appearance has been changed by age or accident.

G．Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable.

【解析】

試題分析: 本文講述了指紋的唯一性和它在刑事案件偵破中的重要作用。人的指紋是具有唯一性的，人的成長，變老，表皮受傷等都不會改變一個人的指紋，即使只有一小部分也可以通過技術(shù)手段繪出人的指紋，正是利用這一點警方才會破獲了很多的犯罪案件，但是如果是刀傷，燒毀就無法顯示指紋了，但這是很危險的。

1.考查對上下文的理解和推理判斷能力。根據(jù)前句內(nèi)容“科學(xué)家們和專家們都證明了指紋的獨特性, 并且還發(fā)現(xiàn)父母沒有遺傳給小孩相同的紋路排列，然而沒人知道這是為什么”可知這句話提到了指紋的唯一性，而G選項內(nèi)容“每個人手指上都有著獨一無二的紋路排列，而且這種排列是不會改變的，”同樣也提到了這一特性，是對上一句內(nèi)容的進一步補充，故選G

2.考查對上下文的理解和推理判斷能力。上句內(nèi)容提到“燙傷，割傷和其它的表皮損害都會被新皮膚給取代，而且還會長出原有的紋路來”，而且第四句說“一些罪犯利用這點而去銷毀他們的指紋，但是走這一步是危險和罕見的”，可知如消除指紋特征，表層皮膚受損不會改變特征，那么只有深層皮膚受損可改變了，故選C。

3.考查對上下文的理解和推理判斷能力。前句內(nèi)容是“由于這種系統(tǒng)的簡單和經(jīng)濟，指紋鑒定已經(jīng)經(jīng)常被用作解決刑事案件一種方法，可知指紋的唯一性可指證身份”，而D項內(nèi)容是“使用特殊的方法，身份確認可以在很短時間內(nèi)成功的達成”，內(nèi)容符合語境，故選D。

4.考查對上下文的理解和推理判斷能力。由前句內(nèi)容“嫌疑犯可以否認對他的指控但是這也許是在徒勞”，可知由于指紋唯一性，即使年齡、面貌或其他特征改變，指紋也不會變，而F項意思“即使他的外表或許因為年齡或者事故而改變，但是他的指紋能證明他是誰”，內(nèi)容可以承接上文，故選F。

5.考查對上下文的理解和推理判斷能力。上文提到“當一個嫌疑犯在犯罪現(xiàn)場留下指紋印的時候，是很難用肉眼察覺的”，而A項內(nèi)容是“特殊的技術(shù)被用于使之現(xiàn)形”，內(nèi)容符合語境，可以承接上文，故選A。
