让我们一起英语说:涟漪

虽然我们可能出生在不同的年代,小时候玩儿的东西也会有很大差异,但我猜无论住在哪里,多数人可能都玩儿过这样一种游戏:几个小伙伴站在河边,依次将薄薄的小石子扔进水里,看谁打的水漂多。


这里的水漂就是涟漪,用英语作文练习英语讲叫 ripple。


涟漪的特别可爱,会以一个点为圆心,不断向四周扩散,所以 ripple 又有动词的词性,意为扩散,涌起。阅读今天的推送,看 ripple 作为动词出现的一个语境,顺便了解一点粗浅的科学知识吧。


EPIC EARTHQUAKES 

Earthquakes are waves that shake the ground beneath our feet. Earth’s land masses are built on giant rocky plates that grind slowly past one another. Sometimes they jolt up and down, causing a massive release of energy at cracks called faults. This energy races through Earth as a high-speed wave, producing an earthquake on the surface.

▸ plate 板块

▸ jolt 颠簸,摇动

▸ fault 地壳岩层的断层

FAST WAVES 

The waves that carry earthquakes speed through英语测试平台 the ground at around 25,000 km/h (15,000 mph), 25 times faster than a jumbo jet.

DANGEROUS WAVES 

Earthquakes often strike under the ocean. A large quake jolts the water above it very violently. This sudden release of energy causes waves to race across the ocean’s surface. The waves carry massive amounts of energy, and when they reach the shore, they can be higher than buildings. They continue on to land as a tsunami — a massive wave that can flatten everything in its path. 

▸ flatten 把……变平


HOW A TSUNAMI HAPPENS 

Energy from an earthquake races through the ocean, producing giant waves that can destroy towns close to the shore. 


WAVES IN SPACE 

As well as physical waves, there are also waves of force and energy pulsing through the Universe. Some scientists believe that gravity makes waves that ripple through space and time, like waves on the ocean. Bigger objects, such as massive black holes, make bigger waves. As gravitational waves travel, they spread out and get weaker, which makes them very hard to detect. 

▸ pulse 跳动,震动

▸ ripple 扩散,涌起


GRAVITATIONAL WAVES 

Scientists are trying to find evidence that gravitational waves are racing through space. Although they have built sensitive wave detectors, no such waves have yet been found.
