W: Dr. Thomas? This is Keet Bradley from the Daily News. I’d like to ask you some questions about(22)the new official standard weight that you purchased.
M: I’d be happy to help you. What would you like to know?
W: First of all, how was the standard weight used?
M: Well, we are a government agency, the Department of Weights and Measures. The people in our department use it(23)to check the scales all over the country. It’s our responsibility(23)to see that all the scales measure a kilogram accurately.
W: How did you check the scales before?
M: We have an old standard weight that we used to use. (24)It had to be replaced because it was imprecise. You see it was made of poor quality metal. It absorbed too much moisture.
W: Oh. So when the weather was humid it weighed more and when it was dry it weighed less.
M: Exactly. And that variation can affect the standards of the whole country. So our department had the new weight made out of higher quality metal.
W: How much did it cost?
M: About 45, 000 dollars.
W: 45, 000 dollars? For one kilogram weight? That’s more expensive than gold. Is it really worth that much?
M: (25)I’m sure it is. Industries depend on our government agency to monitor the accuracy of scales so that when they buy and sell their products there is one standard. Think of the drug industry, for example, those companies rely on high accuracy scales to manufacture and package medicine.
22. Q: What is the conversation mainly about?
23. Q: What was the purpose of the standard weight?
24. Q: Why was it necessary to replace the old standard weight?
25. Q: What does Dr. Thomas probably think about the cost of the new weight?
选项
A、To check the accuracy of scales.
B、To calculate the density of other metals.
C、To observe changes in the atmosphere.
D、To measure amounts of rainfall.
答案
A
解析
由对话中的check the scales all over the country,see that all the scales measure a kilogram accurately可知标准重量砝码是用来检验秤是否准确。故选A)项。
