Question

    It’s sad to learn that a whale has died in the ocean. However, that is not the end for the whale. It gives a lot to other sea animals after death.

When a whale dies, it quickly drops to the bottom of the ocean floor. There the whale’s dead body provides food and nutrients(营养) for deep-sea animals. The remains(残骸) can last(持续) for ten years and build an ecosystem called a whale fall — an “oasis(绿洲)” of life in the deep sea.

Chinese scientists found a whale fall for the first time in the South China Sea this year. The whale fall ecosystem can stay in the deep ocean because of great pressure and cold temperature there. They can stop the body from decomposing(分解) too quickly. The depth(深度) makes it hard for scientists to find the whale fall. There are less than 50 known whale falls in the world.

The whale fall in the South China Sea is about three meters long. Scientists have found several species(物种) near the whale fall. Some fish have started to eat the whale’s tail. A scientist named Xie Wei says the whale fall might be quite recent and needs long-term observation(观察). By studying the whale fall, scientists can better understand how sea ecosystems support life.

【解析】

本文是一篇说明文，介绍了鲸落这一自然现象。

1.

题意：鲸鱼的尸体为深海动物提供了什么？

根据原文There the whale’s dead body provides food and nutrients(营养) for deep-sea animals可知，鲸鱼的尸体能为深海动物提供食物和营养。故答案为Food and nutrients.

2.

题意：中国科学家第一次在哪里发现鲸落？

根据原文Chinese scientists found a whale fall for the first time in the South China Sea this year可知，中国科学家第一次在南海发现了鲸落。故答案为In the South China Sea.

3.

题意：为什么鲸落生态系统能存留在深海？

根据原文The whale fall ecosystem can stay in the deep ocean because of great pressure and cold temperature there可知，因为巨大的压力和寒冷的温度，鲸落生态系统可以停留在深海。故答案为The whale fall ecosystem can stay in the deep ocean because of great pressure and cold temperature there.

4.

题意：南海鲸落附近有没有其他物种？

根据原文Scientists have found several species(物种) near the whale fall可知，南海鲸落附近发现了几个物种。故答案为Yes, there are.

5.

题意：这篇文章主要讲什么？

通读全文可知，本文是一篇说明文，介绍了鲸落这一自然现象。故答案为The whale fall.
