PTE Re-tell Lecture 真实讲座练习题:温室效应

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!


Most people I talk to a totally godsmacked shocked when I tell them up to seven percent all global energy emissions come from concrete, seven percent. And that’s reflection the fact that three hand a half percent of global energy spent heating stuff up to make it. And three percent of carbon dioxide comes out as you know when you add the water you get a huge huge reaction going on and we get the concrete. So can we solve it? Yes, we can. And this is a wonderful Australian story, and it’s actually a Melbourne story and you know the zip on story and I think it’s a great story and it just used the powerstation ashes whatever the world else wants. Crowd plastic just about any kind of waster could be poured into concrete, it’s just forms of this great polymer. I’m exaggerating course but there are lots of things we can do with concrete. And I know they’re a big worries a moment about whether pillars can hold up for long enough one of the great big tower blocks or whether it’s strong enough to survive corrosion near the sea and a big structure. But we will have those answers within the next five to ten years and in the meantime I think a lot of opportunities to be very creative and just one example, where we can make big savings
