Everyone knows what a needle is. Of course there are needles and needles: Needles for sewing machines, needles for injection(注射), you name it. But few people think of the wonder : a needle works in the hands of those who practice acupuncture(针刺疗法).

During the past ten years or so, I have been suffering from terrible headache. It seems to be getting from bad to worse these days . Last night I got a sudden pain in my head. It was so terrible that I could hardly bear(忍受)it. Although I swallowed all kinds of pain-killers(止痛药), I didn’t feel any better, It seemed that there was nothing I could do but phone for a doctor.

One of our neighbours happened to be with us. He was not a doctor, but he timidly(胆怯地) 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(缓解疼痛).

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 miracle , isn’t it?
