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] Such a link in the passage refers most probably to________.

选项 A、IPCC and climate changes
B、global temperatures and sea levels
C、natural changes and human activities
D、human activities and temperature rises

答案 D

解析题目问such a link可能表达的意思。根据题于Such a link定位至第2段倒数第2句。该句提到，the first time they had concluded such a link，而such a link指代前面提到的第二次评估报告发布的结论，即discernible human influence on the climate “人类对气候有明显的影响”，此处“对气候的影响”具体是指前文所述的“气温的升高”，由此可知，Such a link是指“人类活动与气温上升的关系”，因此D项正确。A项“IPCC和气候变化”、B项“全球气温和海平面”和C项“自然变化和人类活动”均不符合语境，可排除。
