1、课时跟踪检测（一） Warm-up & Lesson 1 Pre-reading阅读理解ASatellites in space measure temperatures over large areas of the ocean. They are, however, less specific when it comes to measuring temperatures along the coast. However, there is a new solution.Scientists want people who do water sports to help them gath
2、er coastal climate data. This includes surfers, divers and fishermen. The idea came from new data collected by scientists who are also surfers. The group was led by a scientist in England named Bob Brewin. The group designed a surfboard that could be their laboratory. The results show different wate
3、r temperatures than what the satellites have shown.Coastlines are important to the economy. Large amounts of people use them for business and fun. Coastlines are also important for the environment because they are home to many different plants and animals.Brewin says satellite data alone cannot be t
4、rusted. So, his team wants volunteers to gather data during their water activities. The information the volunteers find will be used along with satellite readings. The scientists think this will result in more accurate information.“We can begin to understand how our coastal environment is responding
5、 to climate change，” Brewin said.They want surfers to check water surfaces and divers to measure temperatures deeper in the water. The information would then go into the scientists database. Meanwhile, a group of scientists from Europe had another idea. The group is interested in boots that some fis
6、hermen use. These boots sense water temperatures. The scientists think the fishermen who wear those boots could be connected to a datacollection system.Many water sports take place in areas that are important for sea life. These locations can be difficult to check, Brewin says. For example, ocean wa

At the underside of the shelf there lives a small fish, the Antarctic cod. For forty years scientists have been curious about that fish. How
21、does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer. Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fishs blood and meas
22、ured its freezing point. The fish were taken from seawater that had a temperature of 1.88 and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to 2.05. That small difference is enough for the fish to live at the freezing temperat
