degrees Fahrenheit. The second was set 6 degrees Fahrenheit higher - what researchers expect water temperatures to average under moderate (适度的) climate change. They heated the third pool to 95 degrees Fahrenheit, what the region could see under a worst­case­climate situation.

　　Essie Rogers, the study's lead author and a Ph.D. student at the University of Queensland, quickly saw a change in the crocodiles' behavior. "Acute increases in water temperature resulted in greatly shorter crocodile dives，" Rogers said in a statement. "Their underwater time halved with every 3.5­degree Celsius increase in water temperature."

　　For Australia's saltwater crocodiles, the changing temperatures could mean the animals might start searching for cooler waters, heading farther south than the species' known range. Franklin said more testing needs to be conducted to get a better understanding of how climate change could affect crocodiles' prey (捕食). "We are not sure what this means, but it's likely that if the water is too hot, crocodiles might move to cooler regions or will seek shelter in deep, cool water pockets to defend their dive time，" Franklin said.

　　1．What do we learn about saltwater crocodiles in Australia?

　　A．They are at the risk of dying out now.

　　B．They are not sensitive to temperatures.

　　C．They don't like spending time underwater.

　　D．They are good at adapting to new environments.

　　解析：选D　细节理解题。根据第一段的"The species is considered one of the most adaptable in Australia"可知，这种鳄鱼适应新环境的能力强。

　　2．Under moderate climate change, the average summer water temperature can reach ________.

　　A．82 degrees Fahrenheit

　　B．88 degrees Fahrenheit

　　C．92 degrees Fahrenheit

　　D．95 degrees Fahrenheit

　　解析：选B　推理判断题。根据第三段的"The first pool was set ... climate change."可知，答案应选B项。

　　3．What Franklin said in the last paragraph shows that crocodiles ________.

　　A．may die out pretty soon

　　B．will change their diving ways

C．will get used to the climate change
