So now I guess

I guess there are scientists right now trying to do that, and I hope they'll succeed because the world would be a much cleaner place, wouldn't it? I think it will be great if they invent something so that we only have to sleep for one or two hours every day.

我想有科学家正在尝试这样做，我希望他们能成功，这样世界会变得更干净，不是吗？如果他们发明一种东西，让我们每天只睡一两个小时，那就太好了。

The first of these is rhythmic, so we're going to turn now -I guess we'll turn off the lights and we're going to go to a couple of slides here.

但是现在，我不知道什么将会发生，所以我猜你将要在周围徘徊并且找个答案出来。
