在PTE中,无论是Summarise Spoken Text 还是 Re-tell Lecture的考题大都是从真实的讲座或者演讲中截取的,中间经常经常夹杂很多不同的环境音.很多同学都反映有时未必是听不懂,而是听不到. 鉴于此,墨尔本文波雅思PTE专门为大家总结了真实讲座的PTE练习音频,相比新闻音频来说,整体更加接近PTE考试的真题,内容方面,我们也会为大家提供考试中存在的近似题,最近我们会持续更新,敬请期待!
So so why should you study stem cells in plants? So the first answer they make really really good stem cells, so there’re excellent at it. And there are also some practical reasons and that you will see some examples of these that plant to make themselves in ways that we can actually study on them, they make them out of surface and so we can watch them, we can watch the birth of a stem cell in its entire life as well as estimates. And then two other things I think are important, one has to do with evolutionary history and I’ll give you more some more about this as well, but the prison animals are actually pretty different and so it’s a way of asking if they both come up with two different things come up with the same solution or something fundamental about that. If two things come up with a different solution to this problem with being a stem cell. Then maybe we have alternative stem cells. And then the final thing I am going to talk about this a few minutes for the end is that we are all very focused on understanding stem cells for our own seek, but plants themselves actually make important stuff, important products for plants and those are actually pretty important for the world.
