Now listen carefully and answer questions 21 to 23.

现在请仔细听，并回答第21至第23题。

MIA: You know that joint presentation we've got to do this semester, Leo?

米娅：利奥，你知道我们这学期必须做的那个联合报告吗？

LEO: On houses of the future?

利奥：关于未来的房屋？

MIA: That's right. I'm a bit concerned – are we meant to come up with creative new suggestions for these houses?

米娅：是的，我有点担心——我们应该为这些房屋提出创新的新建议吗？

LEO: I don't think so. It's more a matter of reporting and evaluating possible developments. But we mustn't be too general, we've got to support our points by referring to specific cases. So that'll need a lot of work.

利奥：我不这么认为，更多的是报告和评估可能的发展。但我们不能太笼统，我们必须通过引用具体案例来支持我们的观点，所以这需要大量工作。

MIA: I'm afraid so. When's it got to be done by?

米娅：恐怕是的，必须什么时候完成？

LEO: In about 6 weeks, so that's not too much of a rush.

利奥：大约6周后，所以不是太紧迫。

MIA: Good. We'd better decide now what type of housing we're going to focus on.

米娅：好的，我们最好现在决定要关注什么类型的住房。

LEO: How about housing for different generations living together?

利奥：不同世代共同生活的住房怎么样？

MIA: We could do. Or accommodation for one person?

米娅：我们可以这样做，或者一个人居住的住所？

LEO: I think someone else is doing that. I was wondering about housing for the elderly? That's likely to become more important.

利奥：我认为其他人正在做这个，我在考虑老年人住房，这可能会变得更加重要。

MIA: Yeah that's true. But I think your suggestion about intergenerational living might be more interesting – let's go with that.

米娅：是的，确实如此。但我认为你关于代际共同生活的建议可能更有趣——我们就选那个吧。

LEO: OK. Now I think the future demand is mainly going to be for accommodation in urban areas. So one way of meeting that demand might be to use existing commercial buildings and adapt them to form accommodation…

利奥：好的，我认为未来的需求主要将是城市地区的住房。所以满足这一需求的一种方式可能是利用现有的商业建筑并将其改造成住宅……

MIA: …or come up with original ways of organising space so that people can live in smaller homes. But I think the solution is to design multi-storey apartment blocks.

米娅：……或者提出组织空间的新方式，使人们可以住在更小的房子里。但我认为解决方案是设计多层公寓楼。

LEO: Building up rather than out, yes.

利奥：向上建而不是向外扩展，是的。
