60秒科学:你见过蚊子变成”落汤鸡”吗?

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:


 

下面是墨尔本悉尼文波PTE雅思培训学校为大家整理的原文材料:

Have you ever wondered what happens to mosquitos in the rain? A raindrop is, like, 50 times heavier than those little suckers. So getting hit by one has gotta hurt, right?

Well, not so much. Because researchers at GeorgiaTech have found that the bugs are so light, speedingwater drops simply brush them aside, withoutimparting much force. The results appear in theProceedings of the National Academy of Sciences.
Previous studies have shown that precipitation canbe a real pain for lots of winged critters. Batsexpend twice as much energy flying through a storm as in clear skies. But what about bugs nobigger than the raindrops themselves?
Researchers used highspeed video to watch mosquitos winginin the rainwell, through aspray of mist in the lab. They saw that when a skeeter and a water droplet meet, the insectbasically hitches a ride for a bit before peeling away off unharmed.
So the bugs go with the flow and offer little resistance. And the drop slows only slightly, keeping its kinetic energy rather than blasting the bug. So for stormtrooping skeeters, resistance is not only futile. Its all wet.
文波陪伴,PTE不难!
