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,[6]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.
5. What is the conversation mainly about?
6. How is the new weight used?
7. Why is it necessary to replace the old standard weight?
8. What does the man 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
四个选项都是动词不定式结构,多表示目的(用途)、打算或将来的动作。根据选项内容可以判断题目询问某物的用途。男士说:“我们部门的人用它来检查全国的(重量)计量器……确保所有的(重量)计量器都能准确地测量一公斤……”,故答案为A。对话中还有提示,在听到问题“how was the standard weight used”时,要注意问题的回答。
