PTE听力口语-科学60秒: 诺贝尔物理学奖

PTE考生目前最大的问题之一就是练习题缺乏。除了有限的基本官方书(PLUS,Testbuilder, OG)之外就没有题了。很多英语基础不是很扎实的同学很难找到练习材料。悉尼文波雅思PTE培训学校专门为澳洲,尤其是悉尼、墨尔本的PTE考生准备了适合PTE听力阅读练习的科学60秒。各位PTE同学可以练习PTE听力中的summarise spoken text和PTE口语中的retell lecture,练习记笔记技巧和复述。


Nobel Prize in Physics
The 2009 Nobel Prize in physics goes to Charles Kao of Standard Communications Labs in England and the Chinese University of Hong Kong for the invention of practical optical fiber communication, and George Smith and Willard Boyle of Bell Labs in New Jersey, for inventing the chargecoupled device, the CCD, making digital cameras possible.

The Nobel Prize in physics goes to Charles Kao, of Standard Communications Labs in England and the Chinese University of Hong Kong, and George Smith and Willard Boyle of Bell Labs in New Jersey. Kao figured out how to transmit light over long distances in optical glass fibers. From the official announcement: “Today, more than a billion kilometers of optical fiber around the world forms the backbone of modern global communication.”

In 1969, Smith and Boyle made your digital camera possible by inventing the chargecoupled device, the CCD: “This device allows electronic recording of images and it replaces the photographic film in cameras. The CCD records the image as a distribution of charge in small cells or pixels, and it outputs the image as a series of digital numbers. The CCD is a crucial component of advanced cameras, and it finds numerous applications in scientific and medical equipment. For example, it gives us the spectacular images of the universe that we can see today.”
