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] Obviously, the word precipitation most probably refers to________.
选项 A、latitude
B、rainfall
C、temperature
D、projection
答案 B
解析 题目问precipitation可能表示的意思。根据题干precipitation定位至第3段，该段提到，wintertime rainfall in…will rise, that meanwhile Australia…are likely to see decreases in autumn precipitation，这里的meanwhile表示“与此同时”，连接rise和decreases，说明前后两句形成对比，前句表示“……地区冬季降雨将增加”，由此可猜测后句表示“……地区秋季降雨将减少”，因此precipitation表示“降水”，故B项正确。A项“纬度”、C项“气温”和D项“预测”均与语境不符，可排除。
