Ⅳ. 跨学科 珠穆朗玛峰气象考察 (2023·盐城中考)阅读理解
中国科学家利用气象站去研究珠穆朗玛峰的气候变化情况及全球变暖对青藏高原的影响。我们一起来了解一下吧！
A team of Chinese scientists and climbers reached the top of Qomolangma at about 12:30 p.m. on Tuesday, May 23. It's the second time since last year for the science expedition(考察) team to reach the top.
The team was made up of 13 Chinese scientists and climbers. They set off at a height of 8, 300 metres for the top at about 3 a.m. After more than 8 hours of hard climbing, they arrived at the 8, 830-metre weather station.
After fixing steel ropes, changing batteries and putting in wind speed and direction sensors (传感器), they finished improving the world's highest automated(自动化的) weather station, which was set up by Chinese scientists last year. Besides, they collected ice-snow samples on the top for further research.
The weather station records temperatures, wind speeds and other key data for studying climate change. Climate scientists have found that global warming has had a large influence on the glacier number on the Qinghai-Tibet Plateau (青藏高原).
Over the last fifty years, the temperature on the Qinghai-Tibet Plateau has risen about 0.5℃ every ten years. Studying the ecosystem (生态系统) of the Qinghai-Tibet Plateau will help scientists have a better understanding of the influence of climate change, and help scientists and the government make proper decisions.
Since the mid-20th century, China has sent different research expedition teams to Qomolangma. But because of limited resources and technologies, many key scientific questions are still unanswered, such as whether global warming can melt the ice at the top of Qomolangma, and how ecosystem can change as height increases to extremity.
1. How many times has the Chinese science expedition team reached the top since last year?
A. Once.
B. Twice.
C. Three times.
D. Four times.
2. 中考新考法 图片理解 Which paragraph best describes the picture below?

A. Paragraph 1.
B. Paragraph 2.
C. Paragraph 3.
D. Paragraph 4.
3. 中考新考法 推断段落大意 What does Paragraph 5 mainly talk about?
A. The way of scientists studying climate change.
B. The effort of government to solve climate change.
C. The influence of climate change on the Qinghai-Tibet Plateau.
D. The importance of studying ecosystem of the Qinghai-Tibet Plateau.
4. What can we know from the passage?
A. The team set off at a height of 8, 830 metres for the top at about 3 a.m.
B. The team collected rock samples on the top for further research.
C. China has set up the world's highest automated weather station so far.
D. All the key scientific questions have been answered up to now.

B [解析]细节理解题。根据“It's the second time since last year for the science expedition(考察) team to reach the top. ”可知,自去年以来,中国科学考察队登顶了两次。故选 B。
