问题     We tend to learn better from experience than from what we have simply been told. So for many in Europe, sleepless nights and airless buses or workplaces have helped to make real the threat posed by global heating. Now statistics are reinforcing the message. Last week the UK had the hottest day on record; 38. 7℃ in Cambridge. New records were set in Germany, Belgium and the Netherlands in July, and June was the hottest month in US history.
    Heatwaves naturally occur in summer, but they used not to be so hot, or so frequent. Experts say that the UK’s sweltering weather last summer was made 30 times more likely by global heating. In a new survey, 77％ believed the recent heatwave was partially or wholly caused by the climate crisis. As temperatures reach unprecedented levels, so does public concern about the environment.
    Some places will experience more severe temperature shifts or will find it harder to adapt than others, often through lack of resources. Poorer countries, which broadly speaking are the least to blame for the climate crisis—emitting less carbon dioxide per capita—will suffer most. A hurricane or wildfire is deadlier when there is little capacity to prepare for it or to speed recovery. Families that spend most of their income on food struggle to eat when crops suffer.
    A recent study found that global heating has already increased global inequality; in most poor countries, higher temperatures are very likely to have resulted in lower economic output than they would otherwise have enjoyed, while richer nations were not harmed to the same degree, and some were potentially able to actually benefit. The research ties in with previous projections that by 2100 the average income in the poorest countries will be 75％ lower than it would be without climate change, and that some wealthy countries might even see higher incomes.
    Yet none of these problems will be fully contained within national borders. Drought and famine are already forcing families from Guatemala, Honduras and El Salvador to attempt to migrate to the United States when they are unable to feed themselves. A 4℃ rise this century, which is now considered a realistic prospect, would produce at least 300 million refugees and drown cities in the US and China. It is the duty of richer nations to do all they can to hold back the soaring temperatures which they did most to produce, and to take what action they can to mitigate their impact—abroad as well as at home. It is also in their self-interest.
The hottest day on record in Cambridge is mentioned to________.
选项 A、make a comparison with other countries
B、show the findings of statisticians
C、explain the sleepless nights of people in the UK
D、stress the severity of global heating
答案D
解析 例证题。根据题干中的The hottest day on record in Cambridge可定位至第一段第四句。举例是为了证明结论，相关的论点往往位于举例之前。此处举例与第一段第二句中的the threat posed by global heating密切相关，即为了表明“全球变暖带来的威胁”，与选项D表达最为接近。故正确答案为D项。原文并非旨在比较各国温度差异，故A项错误。B项过于表面并与文章主题无关，故排除。原文提及sleepless night能加重the threat posed by global heating，即前者是后者的部分原因，C项因果倒置，故排除。故本题答案为D项。
