二、阅读理解。
A tsunami is one of the most powerful and dangerous natural disasters. It is a series of huge ocean waves caused mainly by underwater earthquakes. When the ocean floor suddenly moves during a quake, it pushes a large amount of water upward, creating waves that travel across the ocean at very high speeds, as fast as a jet plane.
Unlike normal waves, a tsunami wave is very long and low in the deep ocean, so ships might not even notice it passing underneath. However, as it approaches the coast and enters shallower water, the wave slows down but grows much taller, sometimes as high as a tall building. The word “tsunami” comes from Japanese, meaning “harbor wave”.
Warning signs of a tsunami can include a strong or long-lasting earthquake near the coast, the ocean pulling back far from the shore very quickly (like a very low tide), or a loud roar from the ocean. If you see any of these signs, you must move to higher ground immediately. Do not wait for an official warning. Remember, the first wave may not be the largest, and tsunamis can last for hours.
