Passage 4

(浙江省宁海县知恩中学2009届高三最后适应性考试)

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  21  to solve the problem of rats. The ancient Egyptians were probably the first people to try to  22  them with poison, and this method is still being used today. This says a great deal about how  23  this method has been. We have set innumerable  24  , from simple wires to  25  machines that drowned the rats in beer! We have tried to inflect them with  26  developed germs. We’ve  27 tried to raise super cats to kill them. However, we are still losing the  28  .

So why can’t man manage to  29  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  30  : wriggle through a hole no  31  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  32  ; jump from a fifth storey window and run away  33  ; and last but certainly not least ,  34  so rapidly that a single pair could have 15,000 babies in one year!

35  all these phyical qualities, we also have the  36  that rats are rather good at not getting caught. They seem to have an almost supernatural ability to  37  when food has been poisoned and a suspicious rat will starve  38  it eats poisoned food. They also seem to be able to  39  a trap with no real difficulty.

One thing looks certain, we had better find a way to  40  these small brown creatures soon, or it may be too late.
