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!
Can photography allow us to see the past? Or is such talk just metaphorical? Philosopher Kendall Walton thinks it can. He argues through unretouched photos, we actually see there are subjects indirectly of course, like seeing around a corner in a mirror, or seeing an amoeba through a microscope. Let’s say you look at an amoeba through a microscope and film what you see. If you watch the film an hour later, don’t you see the same amoeba again? Of course, it might have died or divided before you play the film back, so you don’t see it as it is, but as it was when the camera was running, but you still see it, don’t you? Walton says yes, cameras are the devices that extend our power of vision, like mirrors and microscopes if he’s right. You are not just looking at an image of me now, you are actually seeing me as I was on the September 30th, 2013. In other words, you are seeing the past.
