问题 By far the most common snake in Britain is the adder. In Scotland, in fact, there are no other snakes at all. The adder is also the only Britain snake with a poisonous bite. It can be found almost anywhere, but prefers sunny hillsides and rough open country, including high ground. In Ireland there are no snakes at all.
   Most people regard snake bites as a fatal misfortune, but not all bites are serious, and very few are fatal: Sometimes attempts at emergency treatment turn out to be more dangerous than the bite itself, with amateurs heroically, but mistakenly, trying do-it-yourself surgery and other unnecessary measures.
   All snakes have small teeth, so it follows that all snakes can bite, but only the bite of the adder presents any danger. British snakes are shy animals and are far more frightened of you than you could possibly be of them. The adder will attack only if it feels threatened, as can happen if you take it by surprise and step on it accidentally, or if you try to catch it or pick it up, which it dislike intensely. If it hears you coming, it will normally get out of the way as quickly as it can, but adders cannot move very rapidly and may attack before moving if you are very close.
   The effect of a bite varies considerably. It depends upon several things, one of which is the body-weight of the person bitten. The bigger the person, the less harmful the bite is likely to be, which is why children suffer far more seriously from snake bites than adults. A healthy person will also have better resistance against the poison.
   Very few people actually die from snake bites in Britain, and though these bites can make some people very ill, there are probably just as many cases of bites having little or no effect, as there are of serious illness.
选项 A、in wilder parts of Britain and Ireland
B、in Scotland and nowhere else
C、on uncultivated land throughout Britain
D、in shady fields in England
答案C
解析 解答本题时要看清题干“蝮蛇最可能在……地方被发现”。几乎在任何地方都可以找到蝮蛇，但是它最喜欢呆在向阳的山坡和崎岖的乡间地带，可知C项“在英国各地未开垦的地带”是正确答案。而B项“苏格兰地区，其他地区没有”和D项“在英国背阴的地带”是错误的；根据第一段第五句“爱尔兰没有蛇”可知A项是错的。
