Of all man’s natural enemies, the one that has caused him more trouble than any other must be the common rat. For centuries, man has been 1 to solve the problem of rats. The ancient Egyptians were probably the first people to try to 2 them with poison, and this method is still being used today. This says a great deal about how 3 this method has been. We have set innumerable 4 , from simple wires to 5 machines that drowned the rats in beer! We have tried to infect (感染) them with 6 developed germs. We’ve 7 tried to raise super cats to kill them. However, we are still losing the 8 .
So why can’t man manage to 9 a mere animal like the rat? The answer is simply that the rat isn’t a ‘mere’ animal; it is a very special kind of animal. An average rat 10 : wriggle through a hole no 11 than a $ 1 coin; climb a brick wall as if it were climbing steps; happily leave a building by being flushed down the toilet, and then return the same 12 ; jump from a fifth storey window and run away 13 ; and last but certainly not least, 14 so rapidly that a single pair could have 15,000 babies in one year!
15 all these physical qualities, we also have the 16 that rats are rather good at not getting caught. They seem to have an almost supernatural ability to 17 when food has been poisoned and a suspicious rat will starve 18 it eats poisoned food. They also seem to be able to 19 a trap with no real difficulty.
One thing looks certain, we had better find a way to 20 these small brown creatures soon, or it may be too late.

（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. |
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.
