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 author, climate researchers________.
选项 A、are quite sure about why it’s getting hotter and hotter
B、declared that we humans are the cause why it’s getting hotter
C、have discussed the possible cause why it’s hotter
D、have claimed that changes in nature are the roots of hot days
答案 C
解析 题目问气候研究人员的研究情况。第2段第1句提到，科学家们已经讨论了温度上升的原因，探究是人类活动造成的还是环境的自然变化造成的，由此可知，C项“讨论过气温升高的可能原因”正确。第2段提到科学家对温度上升原因的争论，认为变暖现象可能是人类活动造成的，只是一种推测，因此A项“非常确定气温升高的原因”和B项“宣称人类是天气变热的原因”错误，均可排除。D项“声称自然界的变化是炎热天气的根源”与文章说法不符，可排除。
