问题     The Intergovernmental Panel on Climate Change (IPCC) was set up in 1988 to assess information on climate change and its impact. Its Third Assessment Report predicts global temperature rises by 2100 of between 1.4℃ and 5.8℃. Although the issue of the changing climate is very complex and some changes are uncertain, temperature rises are expected to affect countries throughout the world and have a knock-on effect with sea-level rises.
    Scientists have argued about whether temperature rises are due to human activities or due to natural changes in our environment. The IPCC announced in 2001 that "most of the warming observed over the last 50 years is likely to be attributable to human activities". This was a more forceful statement than in 1996 when the Second Assessment Report stated that there was a "discernible human influence on the climate" which was the first time they had concluded such a link. Many experts believe the faster the climate changes, the greater the risk will be.
    Key points of the projections for climate change globally include that by the second half of the 21st century, wintertime rainfall in the northern mid to high latitudes and Antarctica will rise, that meanwhile Australia, Central America and southern Africa are likely to see decreases in autumn precipitation, that some land areas in the tropics will see more rainfall, and that there will generally be more hot days over land areas. [br] According to the passage, a Chinese city that recorded 45 degrees Celsius at noon on August 4th, 2004, will most probably witness a temperature measuring________at 12:00 sharp in the year of 2100.

选项 A、46.1 ℃
B、1.4 ℃
C、5.8 ℃
D、a number that I do not know

答案 D

解析 题目问2004年8月4日正午测得温度为45摄氏度的中国城市,在2100年12点时的温度可能是多少。根据题干2100定位至第1段第2句。该句提到,IPCC第三次评估报告预测,到2100年全球气温将上升1. 4到5. 8摄氏度,说明2100年此中国城市的气温可能在46. 4至50. 8摄氏度之间,故答案为D项。A项、B项和C项均不在46. 4至50. 8摄氏度之间,故可排除。
