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!
One of the most mind-blowing events in the universe is the explosion of star. In 1054 CE, Chinese astronomers spotted one so bright they could see it in the daylight. Today you can still see a cloud of gas and dust from the same explosion and because a drawing of it looked like a crab. It was called the Crab Nebula, much like a supercharged lighthouse, the center of the star now a neutron star, spins 30 times a second and sends out a beam of radiation, several thousands of these have been discovered each about 20 km across, but with the mass similar to the sun. If we could imagine a cup full of neutron star matter, it would weigh a hundred billion tonnes, but Supernovae more than just impressive bangs. Life forming elements like carbon and oxygen were created inside stars. And the explosion of the star creates even more elements, like gold and platinum to create generations of stars and planets and a variety of attractive ornaments. So in a way, everything is made of star dust, but luckily it’s not all quite as dense as a neutron star.
