A few years I was on a bicycle trip when I got off my bike for a rest. I sat down on the grass. A few seconds later, I was covered in ants. They were swarming all over me so I got up and brushed them off. It was a strange experience but I soon forgot about it. A couple of years later, I was living in Jordan. I had just moved into a modern flat and was unpacking plates when I saw something move out of the corner of my eye. I looked over at the kitchen drawer and there was a cockroach(蟑螂) crawling out of it. I screamed. Then I grabbed a can of insecticide and sprayed it on the cockroach. He ran under the nearby bathroom door. It took me three days before I found the courage to open the bathroom door to see if he was still alive. He wasn' t. Why did I react so violently to one lone insect when a closer encounter with hundreds of ants hardly affected me? The answer is easy: because cockroaches are creepy crawlies(令人害怕的爬虫) and ants aren't. Creepy crawlies are those little bugs which provoke feelings such as apprehension(忧虑), anxiety or aversion(讨厌) - they make your skin crawl. Did you know that some people feel such a fear of bugs that it becomes a phobia(恐惧)? Psychologists have offered many explanations. Some say we associate them with dirt and disease. Or that these are life forms that are so alien to us, that we find them repulsive(排斥的) for their dissimilarity. Insects, however, don't fo llow our rules - they just do what they want and invade our space. Unfortunately, although insects and bugs have been a successful animal species up to now, many of them, like many other species nowadays, are under threat of extinction. Entomologists(昆虫学家) warn that this could upset entire ecosystems and lead to all kinds of disastrous consequences. So my plea to you is: the next time you feel the urge to stamp on, splatter or spray a creepy crawly, give a thought to the planet and stop. 1. Why did the author mention the ants in the beginning?
