42、Everyone knows what a needle is. Of course there are needles for sewing machines, needles for injection, you nameit. But few people think of the wonder a needle works in the hands of those who practice acupuncture. During the past ten years of so, I have been suffering from a terrible headache. It seems to be getting from bad to worsethese days. Last night I got a sudden pain in my head. It was so terrible that I could hardly bear it. Although I swallowed all kinds of pain-killers, I didn't feel any better. It seemed that there was nothing I could do but phone for a doctor. One of our neighbors happened to be with us. He was not a doctor, but he timidly offered his help, saying "Do you mind if I tried acupuncture on you? These needles may possibly do you some good."I agreed. In a moment, he had taken out a few needles from his purse. Without a moment's delay, he fixed a few needles into the skin on my head here and there. Before long, I felt thoroughly relieved. Just then, the doctor sped through my house and said,"Where is our patient?" "Sorry, Doctor, You are too late. It's killed!" I answered in delight. It's a miracle, isn't it?统考英语阅读理解
