问题 By far the most common snake in Britain is the adder (蝰蛇,小毒蛇). In Scotland, in fact, there are no other snakes at all. The adder is also the only British 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 (英雄地)，but mistakenly trying to do-it-yourself surgery and other unnecessary measure.
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 dislikes 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 in Britain and though the 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. [br] We are told that in general British people think snakes are______.

选项 A、unlikely to kill people by their bite
B、more dangerous than they usually are
