（二）阅读理解（30分）
阅读短文，选择最佳答案：
Deep-sea exploration is one of the greatest challenges of modern science.The ocean covers more than 70 percent of our planet, yet more than 80 percent of it remains unmapped and unexplored.
One of the biggest challenges of deep-sea exploration is the extreme pressure.At a depth of 10,000 meters, the pressure is about 1,000 times the atmospheric pressure at sea level.This is why special submersibles are needed to carry humans deep into the ocean.
China has made great progress in deep-sea exploration.The Jiaolong submersible, named after a mythical sea dragon, reached a depth of 7,062 meters in 2012.In 2020, the Fendouzhe (Striver) submersible successfully dived to 10,909 meters in the Mariana Trench, making China one of the few countries capable of deep-sea manned exploration.
Exploring the deep ocean helps scientists discover new species, understand climate change, and find new natural resources.It is truly the final frontier of exploration on Earth.
1.What percentage of the ocean remains unexplored
A.About 50% B.About 70% C.More than 80% D.Almost 100%
2.What is the main challenge of deep-sea exploration mentioned in the passage
A.Darkness B.Extreme pressure C.Cold temperature D.Lack of oxygen
3.How deep did the Jiaolong submersible dive
A.5,000 meters B.7,062 meters C.10,000 meters D.10,909 meters
4.What does "Fendouzhe" mean in English
A.Sea Dragon B.Striver C.Deep Diver D.Explorer
5.What is NOT mentioned as a benefit of deep-sea exploration
A.Discovering new species B.Understanding climate change
C.Finding new resources D.Building underwater cities

Why Sea Exploration Matters
Sea exploration is of great importance to human beings for several reasons.
First of all, exploring the ocean helps us understand marine ecosystems and protect biodiversity.With over 80% of the ocean still unexplored, there are countless new species waiting to be discovered.Secondly, deep-sea exploration leads to important technological breakthroughs in areas like materials science and robotics.Thirdly, ocean research provides valuable information about climate change and helps us find solutions to environmental problems.Finally, the ocean holds rich natural resources that could benefit human society.
In conclusion, pushing the boundaries of sea exploration not only satisfies human curiosity but also brings practical benefits for our future.

二、阅读理解（30分）
阅读短文，选择最佳答案：
The Mariana Trench is the deepest place on Earth.Located in the western Pacific Ocean, it reaches a maximum depth of about 11,034 meters at the Challenger Deep.To put this in perspective, if Mount Everest were placed at the bottom of the trench, its peak would still be more than 2 kilometers below the surface.
Only a few people have ever reached the bottom of the Mariana Trench.The first manned descent took place in 1960 by Jacques Piccard and Don Walsh in the bathyscaphe Trieste.They spent only 20 minutes on the ocean floor and reported seeing some flatfish and shrimp.
Since then, very few manned missions have been attempted.However, unmanned submersibles and robotic vehicles have explored the trench more extensively.Surprisingly, scientists have discovered a surprising variety of life at these extreme depths, including giant amphipods, jellyfish, and even fish adapted to the crushing pressure.
Exploring the Mariana Trench helps scientists understand how life survives in extreme environments and may provide clues about the origins of life on Earth.
1.Where is the Mariana Trench located
A.In the Atlantic Ocean B.In the Indian Ocean
C.In the western Pacific Ocean D.In the Arctic Ocean
2.What is the approximate maximum depth of the Mariana Trench
A.8,000 meters B.9,500 meters C.11,034 meters D.15,000 meters
3.Who made the first manned descent to the bottom
A.Jacques Cousteau B.Jacques Piccard and Don Walsh
C.Chinese scientists D.James Cameron
4.What did the first explorers report seeing
A.Nothing at all B.Flatfish and shrimp
C.Giant whales D.Coral reefs
5.Why is exploring the Mariana Trench important according to the passage
A.To find gold and other treasures
B.To set world records for diving
C.To understand life in extreme environments
D.To build underwater cities

Exploring the Deep Ocean
Exploring the deep ocean is both challenging and rewarding for scientists around the world.
The biggest challenge is the extreme pressure at great depths, which requires specially designed submarines and advanced technology.Darkness and cold temperatures also make deep-sea exploration difficult.
However, the benefits are enormous.Deep-sea exploration helps us discover new marine species and understand ocean ecosystems better.It leads to technological breakthroughs and provides important information about biodiversity and climate change.By pushing the boundaries of sea exploration, we gain valuable knowledge about our planet and unlock secrets of the deep blue world.
