[填空题]December 10th, 2006
Dear Sirs,
I know that your company has a reputation for quality products and fairness toward its customers. Therefore, I’m writing to ask for a replacement for a lawn mower.
I bought the mower about half a year ago at the Watchung Discount Center, Watchung, Nebraska. I’m enclosing a copy of a receipt for the mower.
A month after I bought the lawn mower, the engine failed, and it was repaired under warranty. So far, I have had the engine repaired four times.
Now the engine has broken down again.
I have already spent more than $ 300 on repairs, and I am beginning to seriously question the quality of your mowers.
I am requesting that you replace this mower with a new one.
I hope that you will live up to your reputation of the good customer service that has made your business successful.
Faithfully,
Rod Green

[单项选择]Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and more recently, rubber and plastic. And that was where we stuck, in surgical instrument terms, for many years. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also, in time, to revolutionize the art and science of surgery.
