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,墨尔本悉尼文波雅思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!
The deep question which was one that in some sense drove Einstein was would we know about the sun disappearance by feeling it? by the laws of sun’s gravity? or by seeing the loss of the sun’s light first, which would we see first. According to Newton, we’d actually feel the sun had disappeared because once it goes away, it’s gravity according to Newton disappears instantaneously. So we fly off into the space, even though we still see the sun in the sky for it takes eight minutes for the light from the sun to reach us. Einstein, however, reworked the laws of gravity, and found the gravity doesn’t travel instantaneously from place to place. Instead, it travels at the speed of light. So in Einstein’s reworking, we feel the loss of the sun gravitationally at exactly the same moment that we’d see the loss of the sun by virtue of the sky going dark eight minutes after it happened.
