今天小编给大家整理了3篇PTE口语练习题，PTE口语薄弱的同学赶紧练习啦，希望对你有所帮助，提高口语表达能力，顺利通过2018年PTE考试。
1.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.
2.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.
3.That's Harvard researcher Amy Cuddy. Her talk is the second most-watched on the TED site: 37 million views.
The 2010 study by Cuddy and colleagues that inspired the talk stated that striking power poses can affect your hormone levels, and in turn, your appetite for risk.Fake it til you make it, she said. Strike a pose, and it could significantly change the way your life unfolds.
Problem is: that memorable advice looks suspect.Because several studies, with many more participants, have tried to replicate the original results, and
failed. The most recent attempt involved 247 male college studentsnearly six times more volunteers than were in the original study.
And the new study found that holding poses-dominant or otherwise-had no significant effect on testosterone and cortisol levels, or on risk-taking either.
