W:Dr.Thomas? This is Keet Bradley from the Daily News.I’d like to ask you some questions about 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, people in our department use it to check the scales all over the country.The department of weights and measures, we are a government agency. It’s our responsibility to see that all the scales measure a kilogram accurately so this is the way we use to adjust the scales.
W:How did you check the scales before?
M:We have an old standard weight that we used to use. It had to be replaced because it was imprecise. You see it was made of poor quality metal that 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 a one kilogram weight? That’s more expensive than gold. Is it really worth that much?
M: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.
12. What is the conversation mainly about?
13. How is the new weight used?
14. Why is it necessary to replace the old standard weight?

选项 A、It is a small amount to pay for so much precious metal.
B、It is difficult to judge the value of the object.
C、It is too high for such a light weight.
D、It is reasonable for an object with such an important function.

答案D

解析 男士说:“我肯定(物有所值)。所有产业都依靠我们政府机构来监控他们的磅秤。从而当他们买卖产品时能有一个(重量)标准。”故D正确。根据选项的提示词small、value、reasonable和high,可猜测题目是问对某物价值的评价。“I’m sure it is"是省略句,省略worth it,说明男士认为这个价钱物有所值。
