K: First of all, how is the standard weight used

K: How did you check the scales before
S: 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 was too porous. It absorbed too much moisture.
K: Oh. So when the weather was humid it weighed more and when it was dry it weighed less.
S: Exactly. And that variation can affect the standa
A. How to care for precious metals.

M: Hello, Mrs Smith. I’m from the Daily Mirror. And I’m doing a report on public opinion about the city bus service. So, what do you think of the bus service
W: The bus service Actually I don’t use it that often unless I have to go shopping.
M: What’s ... how could the bus service be improved
W: Well, they could turn up on time. I mean you look at the timetable and you think, oh, well, five minutes to wait, and it turns out to be an hour.
M: Do any other people in your family use the bus service
W: My husband. He uses it more often. But fortunately a girl who works in his office often gives him a lift to work. But when he does need to use it, he’s often angry at it. Once, he waited up to fifteen minutes at the station for a bus. So I think there should be some way of warning people when a bus is not going to arrive and certainly much more frequent bus services.
