单选题Onions (洋葱) I like onions very much. I not only like to eat onions raw (生的天然的), but also like them in a fried dish with pork or eggs in it. As long as the dining hall (过道，会堂) serves onions, I will eat them. Some people have asked me: "Why do you like onions so much?" I said, "An onion a day keeps the doctor away." Some days ago, I had a bad cold (寒冷的，伤风) and a sore (疼痛的，痛处) throat (喉咙). Three days passed, but I was not better at all. So I decided to see the doctor. As I was walking along to the clinic, I coughed badly. Suddenly, someone walking behind me called out my name. I turned around and saw, it was one of my lunch partners. He asked me, "What's wrong with you?" I told him I had a cold and was going to see the doctor. He said, with a smile on his face, "You needn't go to see the doctor." I was puzzled and asked, "Why?" He looked at me and said, "An onion a day keeps the doctor away./
