M: Hi, Lesley! Did you go to the Kent Centre to vote last week?
W: Of course. I'd feel guilty if I didn't exercise my right to vote.
M: Yes, but voting in the UK is optional--so you don't have to do it, whereas in some countries voting is compulsory. (1) If you were in Australia, where the government passed a law that made voting compulsory, you would have had to pay a fine of $ 20 for not voting.
W: And that's because the Australian government believes that voting is a duty and not just a right. Do you think we should also introduce this kind of law in the UK?
M: (2) Well, I'm quite cautious about this, because it could bring about this sort of slapdash attitude towards politics.
W: Oh, sorry. (3-1) What does "slapdash attitude" mean?
M: (3-2) It means doing something quickly and carelessly. Young people might just pick a political party out of a hat--which means to choose randomly--rather than making an informed choice.
W: So some people think that politicians need to improve political education.
M: So compulsory voting would mean a responsibility for the politicians, too.
W: That's right. They need to engage and educate young people. Otherwise reluctant voters may deliberately spoil--or waste--their votes.
M: The government could also include a "none of the above" option on the ballot paper.
W: Can you explain a bit more about that, Rob?
M: (4) Well, it means you tick this option if you don't want to vote for any of the listed political parties.
W: An interesting idea.
