问题     Global warming is a trend toward warmer conditions around the world. Part of the warming is natural; we have experienced a 20,000-year-long warming as the last ice age ended and the ice【C1】______away. However, we have already reached temperatures that are in【C2】______with other minimum-ice periods, so continued warming is likely not natural. We are【C3】______to a predicted worldwide increase in temperatures【C4】______between 1℃ and 6℃ over the next 100 years. The warming will be more【C5】______in some areas, less in others, and some places may even cool off. Likewise, the【C6】______of this warming will be very different depending on where you are—coastal areas must worry about rising sea levels, while Siberia and northern Canada may become more habitable(宜居的)and【C7】______for humans than these areas are now.
    The fact remains, however, that it will likely get warmer, on【C8】______, everywhere. Scientists are in general agreement that the warmer conditions we have been experiencing are at least in part the result of a human-induced global warming trend. Some scientists【C9】______that the changes we are seeing fall within the range of random(无规律的)variation—some years are cold, others warm, and we have just had an unremarkable string of warm years【C10】______—but that is becoming an increasingly rare interpretation in the face of continued and increasing warm conditions.
A)appealing I)melted
B)average J)persist
C)contributing K)ranging
D)dramatic L)recently
E)frequently M)resolved
F)impact N)sensible
G)line O)shock
H)maintain
【C2】
选项
答案G
解析 空格前面有介词in，后面也有介词with，因此空格处需要填入名词，能和in和with搭配。文章下一句提到温度继续升高可能就不是自然原因了，这一句也提到我们现在已经达到了一个温度，句子后面部分是间冰期温度，因此这里是将两者相比较，因此空格处动词应该有“一致”或“比较”的意思。由此确定名词line为本题答案，意思为“一致”。备选名词中，average和impact均无法与in和with一起搭配，可以排除。
