考查名词复数和比较级的用法。“one of the+形容词最高级+名词复数”表示“最……之一”，所以第一空
应该用名词复数形式，country的复数是countries；在比较级中，表示同一范围内的比较，用“any
other+名词单数”，表示“其他任何一个……”，加拿大不属于亚洲，是不同范围的比较，用any+名词单
数，这里用any country表示“任何一个国家”，所以第二空用any。故选C。

四、阅读理解
The Aurora Borealis(北极光), also known as the Northern Lights, is one of the most breathtaking natural
wonders on Earth. This celestial phenomenon occurs in the polar regions, where charged particles from the sun
collide with gases in the Earth’s atmosphere, creating a dazzling display of colored lights that dance across the
night sky.
Experiencing the Northern Lights is a once-in-a-lifetime event for many people. To fully appreciate this
wonder, it’s important to approach it with patience and an open mind. The lights are unpredictable—they may
appear suddenly and fade away just as quickly, or they may linger for hours, painting the sky in shades of green,
purple, and pink.
Communicating with this natural wonder means more than just watching it. It involves feeling the cold air on
your skin, listening to the silence of the Arctic night, and marveling at the sheer power of the sun’s energy. Many
who have witnessed the Northern Lights describe it as a spiritual experience, one that makes them feel connected to
the universe in a profound way.
Protecting the Northern Lights and their habitat is crucial. Light pollution from cities and human activities
can dim the visibility of the lights, making it harder to see them. By reducing light pollution and preserving the
Arctic environment, we can ensure that future generations will also have the chance to witness this amazing natural
phenomenon.

A．Collisions between charged particles and atmospheric gases.
