M: Hi, May, how about going swimming this weekend?W: Oh, sorry, Rob, I don't know how to swim.M: Really? I think swimming is a very popular activity in the UK and it is said that four in five adults in the UK are good swimmers.W: You're right. Most people recognize that swimming is very important for safety and good for fitness. But maybe some people weren't introduced to the water early enough and they don't have the confidence to start swimming later in life. Just like me.M: And in fact experts say that the best time to learn is when we're babiesor children.W: That makes sense. I think a lot of babies are natural swimmers, so it's good for them to be in the water from an early age.M: As long as they've been supervised well.W: Definitely! Babies as young as three months old can start swimming. But there are still many people like me who didn't start learning swimming in our childhood. What can those people do?M: Ah, well there are a number of schemes to encourage people to swim. I know one called "Big Slash", which celebrates swimming and wants to get more people into the water, whether they're adults or children.W: That sounds wonderful. Can you tell me more about this scheme?M: They always arrange many swimming classes for adults and the coach will use some techniques to encourage adults to swim.W: I am interested in it. Do you know how I can participate?M: Well, this Saturday in Central Pool they will hold an orientation session for beginners. If you have time, you can go and have a look.W: Oh, thanks a lot.1.How many adults in the UK cannot swim according to the conversation?A) 1/4.B) 4/5.C) 1/5.
