Question

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

When a whale dies, it quickly sinks (下沉) to the bottom of the ocean floor. There, the whale body provides food and nutrients (营养) to deep-sea animals, which are often hungry for food. The remains can last for hundreds of years and create a complex ecosystem called a whale fall (鲸落).

Chinese scientists found a whale fall for the first time in the South China Sea during a deep-sea expedition (考察) carried out by oceanic research vessel (舰) Tansuo-1, which finished its expedition on April 2, 2020. Tansuo-1 carried the manned submersible (潜水器) Shenhai Yongshi, which is able to dive to a depth of 4,5000 meters.

The whale fall in the South China Sea is about three meters long. Scientists have found several species (物种) of shrimp and fish near the whale fall. Some fish have started to eat the whale’s tail. The whale fall might be quite recent and needs long-term observation (观察), according to Xie Wei, a scientist who took part in the expedition.

The whale fall ecosystem can exist in the deep ocean because great pressure and cold temperatures there prevent body from decomposing too quickly. But the depth also makes it hard for scientists to discover them. There are about 50 known whale falls in the world.

By studying the whale fall, scientists can better understand how marine (海洋的) ecosystems support life and how to protect biodiversity (生物多样性) resources in the deep sea.

【1】What does the writer try to describe in the second paragraph?

A.when a whale fall happen.B.where a whale fall happen.

C.why a whale fall happen.D.how a whale fall happen.

【2】Which sentence about the whale fall in the South China Sea is wrong?

A.It was found during a deep-sea expedition.

B.There was several species of shrimp and fish around it.

C.Scientists have finished the study of it.

D.Scientists from China found it on April 2, 2020.

【3】The underlined words “decomposing” in Paragraph 5 means _________.

A.putting inB.going badC.falling overD.setting off

【4】Why do scientists study the whale fall?

a. To understand how marine ecosystem support life.

b. To find how long the whale fall is.

c. To protect biodiversity resources in the deep sea.

d. To study whether fish eat the whale’s tail.

A.a bB.a cC.b cD.b d

【5】Which magazine can we probably find this article in?

A.Science.B.Geography.C.Mystery.D.Travel

【5】A

【解析】

鲸落指鲸死去后沉入海底的现象。当鲸在海洋中死去，它的尸体最终会沉入海底，生物学家赋予这个过程为鲸落。一座鲸的尸体可以供养一套生态循环系统长达百年。2020年4月2日，中国科学家在南海首次发现一个约3米长的鲸落。

【1】

推理判断题。根据短文第二段的描述可知，在这一段中，作者描述了鲸鱼死亡，沉入海底，为海洋中其他生物提供食物和营养。概括来说，这一段介绍了鲸落是如何发生的，故选D。

【2】

推理判断题。根据第四段“The whale fall might be quite recent and needs long-term observation (观察), according to Xie Wei, a scientist who took part in the expedition.”可知，科学家们在南海发现的鲸落需要长期的观察，C选项不符合文意，故选C。根据第三段“Chinese scientists found a whale fall for the first time in the South China Sea during a deep-sea expedition (考察)”可知A符合文意；根据第四段“Scientists have found several species (物种) of shrimp and fish near the whale fall.”可知，B符合文意；根据第三段“Chinese scientists found a whale fall for the first time in the South China Sea during a deep-sea expedition (考察) carried out by oceanic research vessel (舰) Tansuo-1, which finished its expedition on April 2, 2020.”可知D符合文意。

【3】

词义猜测题。A“放入”；B“变质”；C“跌倒”；D“动身，出发”。根据语境“The whale fall ecosystem can exist in the deep ocean because great pressure and cold temperatures there prevent body from decomposing too quickly.”“鲸落生态系统能在深海存在，因为那里巨大的压力和低温阻止了尸体快速……”，结合常识可知，动物死去之后，尸体会很快变质、腐烂。因此我们可以猜测decomposing的意思与B选项going bad接近，故选B。

【4】

细节理解题。根据短文最后一段“By studying the whale fall, scientists can better understand how marine (海洋的) ecosystems support life and how to protect biodiversity (生物多样性) resources in the deep sea.”可知，通过研究鲸落，科学家们能更好地了解海洋生态系统是如何养育生命以及如何保护深海里生物多样性。由此可知a和c符合文意，故选B。

【5】

推理判断题。A“科学”；B“地理”；C“谜，秘密”；D“旅行”。根据文意可知，这篇短文讲述了中国科学家在南海首次发现鲸落，介绍了鲸落是怎样发生的，以及鲸落的意义。这样的文章属于科学类的，A选项符合文意，故选A。
