蜘蛛恐惧症便是一种害怕蜘蛛等蛛形动物的恐惧症。
This phobia is quite common, affecting as many as 1 in 3 women and 1 in 4 men.
这一恐惧症非常平常,影响着三分之一的女性和四分之一的男性。
The sight of a spider can trigger(诱发) a fear response,
看见蜘蛛会诱发恐惧心理。
but in some cases, simply an image of an arachnid or the thought of a spider can lead to feelings ofoverwhelming(难以掌控的) fear and panic.
有的时候,一张蛛形动物的图画或仅仅是想到蜘蛛的样子都会导致难以掌控的恐惧惊慌。
So why are so many people terrified of arachnids?
为何有那样多人都害怕蛛形动物呢?
While there are an estimated(估计)35,000 different spider species, only around a dozen pose any type of real threat to humans.
虽然世界上已知有35,000种区别的蛛形动物,但仅有其中的十几种会危及人类。
One of the most common explanations for this and similar animal phobias is that
一种针对蛛形动物恐惧症或是别的动物类恐惧症最为平常的解释是
such creatures once posed(导致)a considerable threat to our ancestors(祖先) who lacked the medical know-how(专门知识) and technological tools to address(处理) injuries from animals and insects.
这类动物曾经对咱们的祖先造成为了很大的威胁,而她们缺少医疗科学手段治疗昆虫动物导致的伤口。
As a result, evolution contributed to a predisposition(倾向) to fear these creatures.
因此呢,生物进化使得人们容易对这类动物产生恐惧心理。
