PTE听力口语练习-科学60秒:Recycling The Lithium Ion Batteries

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,PTE听力口语-科学60秒-Frosty Moss练习记笔记技巧和复述。废话少说,下面开始:

Lithium ion batteries power everything these days from smartphones to electric cars.

They’ve been a great advance in portable power storage.
On the downside, their spread also makes a big contribution to electronic waste dumps often found in developing countries.

But IBM scientists in India may have come up with a way to decrease the numbers of discarded batteries while also bringing electricity to underserved parts of the world.

They developed an experimental power supply, called the UrJar, consisting of reusable lithium ion cells salvaged from three-year-old laptop battery packs.
For a study of the technology, the researchers enlisted street vendors who had no access to grid electricity.
Most users reported good results.
Several of them used the UrJar to keep an LED light going for up to six hours daily.
For one participant, the power supply meant keeping the business open two hours later than usual.
IBM presented its findings the first week of December at the Symposium on Computing for Development in San Jose, California.
The UrJar isn’t ready for the market quite yet.
But it shows that one person’s trash could literally light up someone’s life halfway around the world.
