PTE阅读练习题训练

　　PTE学术英语考试,英文名称Pearson Test of English Academic(PTE Academic),也被译为培生英语考试，是由培生教育集团(Pearson)开发并得到GMAC(Graduate Management Admission Council )认可的一款新的基于电脑的国际学术英语考试。它为那些需要学术英语的机构例如大学，高等学府以及政府部门提供了一个真实的衡量考生能力的工具。为需要通过英语考试获得赴英语国家学习机会的非英语国家的学生提供了一种新的选择。　PTE阅读薄弱的同学赶紧收藏啦!什么?你在PTE其他科目也遇到瓶颈了?

　　一.You may have spotted V-shaped squadrons of geese heading south this fall.

　　But for many migrants-like smaller songbirds-nighttime is the right time, when it comes to migration. Winds are gentler.

　　And darkness helps them avoid airborne attacks.Of course darkness also makes it harder for us to see them.Which is where weather radar comes in.

　　These radars were designed to detect water drops in the air, precipitation in the air.Jeff Buler, an ornithologist and aeroecologist at the Universityof Delaware.

　　They also detect any other large object that will reflect back radio energy.It essentially sees insects and bats and birds as large drops of water.

　　今年秋天，你可能会看到一群v形的大雁向南飞去。

　　但是对于许多迁徙者来说，比如小型的鸣禽，在夜间迁徙是合适的时机。风是温和的。

　　黑暗帮助他们避免空中攻击。当然，黑暗也让我们更难看到它们。这就是天气雷达的作用。

　　这些雷达被设计用来探测空气中的水滴和空气中的降水。杰夫·布勒，特拉华大学的鸟类学家和航空生态学家。

　　他们还能探测到任何其他能反射无线电能量的大型物体。它本质上把昆虫、蝙蝠和鸟类视为大水滴。

　　二.Computer models of the splashes revealed interesting details.At the moment the blob of liquid makes contact with the surface, the bottom of the drop flattens out and the pressure increases.The ring of pressure spreads towards the drop's edges. If the surface is too hard, the ring of high pressure creates tiny droplets that explode from the main drop's edges.But the softest surfaces deform in response to the drop hitting them- and that prevents the pressure from getting high enough to cause that explosion.Sadly, you won't see squishy coatings on urinals just yet, or in your laboratories- antisplash materials are too frail.The softest ones are quite delicate so you wouldn't be able to make a laboratory bench with them, they'd get damaged quite quickly.

　　电脑模型的飞溅揭示了有趣的细节。在液体接触表面的那一刻，液滴的底部变平，压力增大。压力环向水滴的边缘扩散。如果表面太硬，高压环会产生微小的液滴，从主滴的边缘爆炸。但是，最柔软的表面会变形，以应对撞击，从而防止压力升高到足以引起爆炸的程度。遗憾的是，你在便池上看不到粘糊糊的涂料，或者在你的实验室里——防溅材料太脆弱了。最柔软的是非常脆弱的，所以你不能用它们做实验室的工作台，它们会很快被损坏。
