标题:全球变暖 体裁:说明文 难度:★★★ 建议用时:7分钟 正确率: /4
(2025·南通期末)Maybe we did not feel it at that time. But in September, there was a shaking(摇晃) under our feet for more than a week. Now, scientists find that it is because of global(全球的) warming.
The shaking came from Earth's crust. It is the shell of the Earth, just like the skin of an apple. It lasted for nine days and went across the whole world.
The study shows that it started in eastern Greenland. Because of global warming, at the foot of a mountain, the ice got thin. It couldn't carry the rocks(岩石) on it, and the 1,200-metre-high mountain came into small pieces. The rocks all fell down into the sea. This made a really big tsunami(海啸). It was about 110 metres high. Over the next few days, the water moved back and ahead, hitting the cliffs(崖壁).
Luckily, nobody was hurt. But scientists believe more things like this will take place because the world is getting warmer.

19. D 代词指代题。根据“Maybe we did not feel it at that time. But in September, there was a shaking under our feet for more than a week. Now, scientists find that it is because of global warming.”可推知，这里的“it”指的是前面提到的“a shaking”，即地面的摇晃。故选D。
20. A 细节理解题。根据“The shaking came from Earth's crust. It is the shell of the Earth”可知，摇晃来自地壳，地壳就是地球的外壳。故选A。
21. B 图示理解题。图示的正确顺序应是，“at the foot of a mountain, the ice got thin”①山脚下冰变薄；“It couldn't carry the rocks on it, and the 1,200-metre-high mountain came into small pieces.”③不能承受岩石重量，山崩；“The rocks all fell down into the sea. This made a really big tsunami.”②然后形成巨大海啸；“Over the next few days, the water moved back and ahead, hitting the cliffs.”④海水前后冲撞崖壁。根据文章内容，正确顺序是：①→③→②→④。故选B。
22. D 细节理解题。根据“scientists believe more things like this will take place because the world is getting warmer”表明全球变暖会持续引发各种类似的变化，也就意味着全球变暖将持续改变世界。故选D。
