(2017·江苏省重点中学高三联考)In the western Pacific Ocean lies the deepest

place on the planet — the Mariana Trench, which runs as deep as about 7 miles below

the ocean's surface. That's greater than the height of Mount Everest measuring about

5 and a half miles above sea level.

The Mariana Trench is home to a variety of sea life.

Coral reefs and underwater volcanoes are all found there.

But because few humans have been able to go far into the

trench, scientists know little about it.

Now they are working to change that. Recently, the Okeanos Explorer has been

on an exploration there. Remotely operated vehicles sent out from it are taking

videos of life in its deepest, darkest areas. Scientists around the world, along

with the general public, can watch the videos in real time. These videos are showing

the most mysterious parts of the ocean. Much of the area that the Okeanos Explorer

is exploring has been protected since 2009 as part of the Marianas Trench Marine

National Monument. Covering more than 95,000 square miles, it is one of the world's

largest marine protected areas.

It's very dark, so the animals must use many other senses other than sight to

understand their surroundings, find food and escape from enemies. The water is also

very cold — slightly above freezing — and its pressure is extremely high. That

means only certain animals can live there, like shrimp, crabs, and starfish.

So far, the expedition's cameras have filmed a variety of rarely seen deep­sea

creatures, including ghost sharks, huge lobsters, and sea pigs. Perhaps the most

amazing sight is beautiful red jellyfish that scientists have never seen before.

Scientists hope this expedition will help them unlock the mysteries of the

Mariana Trench. They'll learn about the deep­sea animals and plants found there.

They'll also study its unique features, including underwater mountains, mud

volcanoes, and hot springs produced by the volcanoes.

They say that this knowledge will also help scientists better understand how

the deepest part of the ocean affects the rest of the world. “The ocean plays a

role in the air we breathe, the food we eat, and the transportation of the goods

we buy — not to mention the weather and climate change,” a scientist said. “The

deep sea may also hold cures for some diseases. How will we know what is out there

if we aren't looking into it?”

语篇解读:本文是一篇新闻报道。最近,科学家们对世界上最深的地方——马里亚纳海

沟进行了一次探测。通过探测,他们对世界上最深的地方的生态有了初步的了解。

1.What do we know about the Mariana Trench from the text?

A.Sea life can hardly be found there.

B.It has never been explored by humans.

C.It's the world's largest marine protected area.

D.It's lively even as the deepest place in the world.

解析:选D 细节理解题。根据第一段的内容和第二段的“The Mariana Trench is home

to a variety of sea life. Coral reefs and underwater volcanoes are all found there.”

可知,尽管马里亚纳海沟是世界上最深的地方,但是海沟里依旧生机勃勃。故答案选D项。

2.What does the author want to say in Paragraph 4?

A.Living conditions are tough there.

B.The surroundings make animals much stronger.

C.Animals there are slow in reacting to potential threats.

D.Animals' sight is severely damaged by high water pressure.

解析:选A 推理判断题。根据第四段的内容,尤其是“It's very dark,so ... The

water is also very cold — slightly above freezing — and its pressure is extremely

high”“only certain animals can live there”等信息可知,马里亚纳海沟的生存条件

是很恶劣的。故答案选A项。

3.What is implied in the scientist's words in the last paragraph?

A.He feels proud of what they have done for humans.

B.It's worthwhile to take effort to explore the Mariana Trench.

C.Scientists should spend more time studying the oceanic climate.

D.There're many challenges for the scientists to explore the ocean.

解析:选B 推理判断题。根据最后一段科学家所说的话可知,海洋同人类的生活息息

相关,且深海可能会为某些疾病提供治疗方法。故可推知,他认为花费精力探索马里亚纳海

沟是非常值得的,故答案选B项。

★ is the best title for this text?

A.The Most Mysterious Ocean

B.A Special Experiment on the Ocean

C.Searching for Precious Animals

D.Exploring the Deep Sea
