According to the news, ice from Greenland gives information about [br]
Scientists say they can tell what air and sea conditions were like hundreds of thousands of years ago. They say pieces of ice taken from Greenland provide such information. Scientists took the ice from more than 15 miles deep in huge masses of ice that float on the sea. The ice represents 25,000 years of history. [23B] It provides one of the clearest records of ancient weather.
[24C] European and American scientific teams have been studying ice from the same area to confirm each other’s findings. They measured the oxygen and carbon dioxide in the ice for the temperature. From these measurements, the scientific teams say that [25D] the past 10,000 years is the only period during which temperature has not changed very much.
选项
A、the weather must have been warmer.
B、the weather must have been colder.
C、the weather had remained almost the same.
D、the weather had changed a lot.
答案
D
解析
根据常识,从两万年前到现在气候不会保持不变,故[C]很可能不是答案。再由…the past10.000 years is the only period during which temperature has not changed very much可推断两万年前的气候总在变化之中,故答案为[D]。
