PTE SST新题高频机经 Visualization of fossil fuel 背景+数据图片

化石燃料可以说是人类社会至关重要的能源之一,就连PTE都一而再再而三的考到这道题。墨尔本文波PTE今天就为大家带来了PTE听力SST中有关化石燃料这道题的相关背景,继续阅读有惊喜喔?!

Fossil fuels (coal, oil, gas) have, and continue to, play a dominant role in global energy systems. Fossil energy was a fundamental driver of the Industrial Revolution, and the technological, social, economic and development progress which has followed. Energy has played a strongly positive role in global change.

However, fossil fuels also have negative impacts, being the dominant source of local air pollution and emitter of carbon dioxide (CO2) and other greenhouse gases. The world must therefore balance the role of energy in social and economic development with the need to decarbonise, reduce our reliance on fossil fuels, and transition towards lower-carbon energy sources.

谈及化石燃料必然离不开几点因素:

1.化石燃料是什么?

2.化石燃料的优点和缺点?

3.人们目前对化石燃料的消耗状态?

4.不同的国家对于化石燃料的依赖程度?

5.如何减少或控制人类社会对化石燃料的依赖?

PTE SST这道真题就总结了以上几个问题的答案:

发达国家80%-90%的能源来自于化石燃料

80%-90% of the energy comes from fossil fuel for the majority of developed countries.

化石燃料并非可持续的能源

However, fossil fuel is not sustainable to some extent.

原因有三点:

1. 容易获取的化石燃料是有限的

Fossil fuels with easy access are finite.

2.化石燃料对空气和气候造成的污染是不可逆的

Burning fossil fuels causes pollution to air and climate, which is harmful to all human beings.

3.化石燃料不丰富的国家可能会有安全问题

If a country largely depends on other countries for fossil fuels,  this dependency could cause security  concern.

考试的时候只要答出fossil fuel的特点和这三点原因即可。

文波PTE每一次为大家总结机经的时候都不仅仅是着眼于机经,众所周知,随着越来越多的考生放弃雅思转考PTE之后,培生官方便越发看中考题中涉及到的背景,可以说是天文地理,人文科学,历史遗迹,社会问题等等话题五一不有,换句话说,考题的内容是有限的,而题目本身涉及到的背景却是无限的。

当谈到化石燃料的问题,我们必然要谈到化石燃料的消耗问题,when it comes to energy consumption, the most convincing evidence is data, in other words, numbers. 在这里为大家提供一个非常好的网站,https://ourworldindata.org/fossil-fuels

这个网站有很多跟社会问题相关的图表,非常适合大家在了解背景之余练习DI,将DI与Retell Lecture和SST完美结合起来,每一张图表下面的解释说明堪称DI能用到的标准模版。大家来看看下面这张煤的生产量的图表,以及ourworlddata对这张图表的解释说明。

Coal production by region

The visualisation below shows recent trends in coal production by region, since 1981. Overall, we see that global coal production more than doubled over this period. Although too early to confirm, global coal production appears to have peaked over the years 2013-14, with several years of declining production since. This would represent a significant peak in global energy, with coal being the first fossil fuel energy source.

The majority of growth in global coal production has been sourced from the Asia Pacific region, with 5 to 6-fold growth over the last 30 years. Total output from Europe, Eurasia and North America has declined during this period. Asia Pacific now produces more than 70 percent of coal, up from around one-quarter in 1981.

你是否发现了熟悉的字眼?可以说是十分高级好用的DI模版,这些图表几乎和PTE考试用到的图表如出一辙,同学们在练习DI时喜欢去Google搜索图片来练习,但是总有那么些时候看着图表说不出口而且也不知道正确答案是怎样的,ourworlddata简直完美的解决了这个问题,以后大家对图表的练习可以上这个网站,一方面可以普及相关背景知识,另外一方面可以练习口语DI,一石二鸟,易如反掌。
