Climate change is bad news for the world’s coral reefs. As global temperatures increase, the world’s glaciers melt, 【小题1】 （cause） sea levels and ocean temperatures to rise. These conditions have led to coral bleaching（白化） events, 【小题2】 the coral turns white and slowly dies, unable to survive in its changing environment.

Global sea levels 【小题3】（expect） to rise about 1.5 feet by 2100, meaning coral reefs will be deeper underwater than they were 【小题4】（previous）in. The deeper the coral, the less light it receives, and the less 【小题5】（able） it has to make food. This has potential to change the entire ecosystems of reefs and the marine life they support.

But a new study from a team of 【小题6】（researcher） at the National University of Singapore （NUS） provides a ray of hope. They studied nearly 3,000 corals from 124 species at two reefs off 【小题7】 coast of Singapore: Pulau Hantu and Raffles Lighthouse. The water where these reefs live is 【小题8】（cloud）, murky and thick with sediment（沉淀物）.

The light reaches down about 26 feet, yet there are corals growing well 【小题9】 that level and below. They’ve adapted to surviving under the changing conditions. Researchers say it’s likely that these corals will survive sea-level rise, according to the findings 【小题10】（publish） in the journal Marine Environmental Research.
