专题04 阅读理解D 【Passage 1•广东省东莞市2020-2021学年高一下学期期末英语试题】 Some of the oldest art in human history is being damaged, scientists say. And climate change may be speeding up its loss. New research reports that ancient rock art in Indonesian caves is degrading over time, as bits of rock slowly break off from the walls. It's a huge loss for human history. Salt crystals（结晶）building up on the walls are a key part of the problem, the study suggests. These salt crystals go into the cave walls, changing sizes as temperatures rise and fall. This process causes the rock to slowly break down. Salt crystals may become larger when exposed to repeated changes between wet conditions and periods of drought. These kinds of changes are expected to become more obvious as the climate continues to warm. In particular, the researchers say, climate change may cause more intense El Nino （厄尔尼诺）events in the future. These events can strengthen the kinds of conditions that help salt crystals form Scientists are still debating the exact influence of climate change on El Nino, a natural climate cycle that drives changing patterns of warming and cooling in the Pacific Ocean. The new study, led by Jillian Huntley, examined 11 ancient cave art sites in South Sulawesi, Indonesia. The researchers found evidence of salt formation at all 11 sites. It's merely a small part There are more than 300 known eave art sites around the region. The researchers note that salt crystals may indeed be part of the problem, adding that climate change is a growing threat, one that deserves more attention. 12．What is the main cause of the rocks breaking off from the wall? A．Weather patterns. B．Salt crystals. C．Wet conditions. D．Drought Periods. 13．Which of the following may researchers agree with? A．El Nino events prevent salt crystals forming. B．Climate change makes little difference to El Nino. C．Salt crystals may become much larger in wet conditions. D．Constant warm weather may cause salt crystals to change size. 14．Which
