阅读下列短文,从每题所给的四个选项中,选出最佳答案

A couple of years ago, I received a $ 600 insurance dividend (保险股息).Sitting at the kitchen table, my wife and I discussed what we might do with the money. I realized now that the refrigerator overheard our talk. The very next day it went wrong. The repairman told us we needed a new unit. Cost:$600. Not long after that, we got a refund(赔偿金)from the shop, enough to pay for a trip to Mexico. “I’ve something to tell you,” I said to my wife in a low voice. “How about the living-room?” she suggested. I remembered the color TV set was there. “No, not there. Let’s go out.” I showed her the check as we stood on the driveway. We held each other excitedly and hardly noticed the rain. My car was parked within5 meters. I didn’t think anything about it at the time. As I started for the airport the next day, the car began making strange sounds. Changing the engine cost about $ 1, 000.

Then I looked through our financial records. I discovered that during the last ten years we spent all our “found money” repairing a hot water heater, a television and a stove.

I never mention money in front of our mechanical equipment. But if this article is published and I am paid for, the word processor(文字信息处理机)is going to go for sure. It’ll know.
