PTE听力口语练习素材:科学60秒-Better Car Labeling

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。墨尔本文波雅思PTE培训学校专门为墨尔本,悉尼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。废话少说,下面开始:

60秒科学:Better Car Labeling Could Pump Up Fuel Efficiency


60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

Quick: which saves more fuel? Boosting miles per gallon from 10 to 11? Or from 33 to 50?

Neither. They both save the same amount—one gallon of gasoline every 100 miles. And that’s why some behavioral scientists think gallons per mile is a better metric. Because it tells you exactly how much fuel your car will burn per mile traveled. As a result, the U.S. Environmental Protection Agency added gallons per 100 miles to fuel economy labels in 2013.

Now new research suggests that’s not the only way to better inform new car buyers of the fuel efficiency of their vehicle.

To test what works best, management researchers at Duke University’s business school offered would-be car buyers a host of labeling options in an experiment. The labels ranged from gallons of gas used per 100 miles to cost of gas over 100,000 miles.

When consumers saw that cost-of-gas label, they picked the most fuel efficient car every time. The research appeared in the Journal of Public Policy & Marketing. [Adrian R. Camilleri and Richard P. Larrick, Metric and Scale Design as Choice Architecture Tools]

The finding suggests that cost is the main driver for people to opt for fuel efficiency. And if lifetime fuel cost is what matters, maybe that ought to be on the new car labels, too.
