Question

（二）   66  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.  67   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 be recorded easily.  68  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. 69  . When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye.   70  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.

【小题1】G
【小题2】C
【小题3】D
【小题4】F
【小题5】A

解析试题分析：此题型为补全对话。兼有完型填空和情景对话的特点。首先，需要在空白处填上适当的，也就是符合语境的句子，换句话说，句子需要和它紧挨着的前后两句有紧密的衔接关系。首先，可根据句子意义的相识性和关键词索引等对答语进行归类。第一类：B.E.F第二类：A.D第三类：C.G
根据此方法：
【小题1】G考察上下文理解和句意完整。根据空白句在句意上对上一句内容的进行补充，推出G
【小题2】C考察上下文理解和句意完整。根据空白句在句意上对上一句内容的进行补充，作者上句提到outer skin ,则此处为：inner skin ，推出C
【小题3】D考察上下文理解和句意完整。根据下句中的关键词method，此处也应有相同的主语，推出D
【小题4】F考察上下文理解和句意完整。根据B选项的关键词his，显然替代上句中的罪犯 故选F
【小题5】A考察上下文理解和句意完整。根据上句和空白句信息的关联性，空白句中的them和上句中的they 方能推出E
考点：任务型阅读，句型划分和句意判断
点评：要做好该类型题，需用归类法&信息关联法&经验法&关键词法，用已有的句型知识帮助自己做出判断。试举一例，以本题为例，用信息关联法解题，70题，根据上句和空白句信息的关联性，空白句中的them和上句中的they 均指代犯罪份子在犯罪现场留下的指纹，此为递进关系，环环相扣。考生平时多注意这方面的训练。
