1、Unit 3 Under the sea (建议用时：50分钟).阅读理解A(2020昆明高三模拟)Finding fish is going to get harder as climate change continues to heat the worlds oceans. A new study finds that warming seas over the past 80 years have reduced the sustainable catch of 124 species of fish and shellfish. A sustainable catch refers

2、to the amount that can be harvested without doing longterm damage to the health of populations of some species.Overfishing has made that decline worse, researchers say. Overfishing refers to catching so many fish that the size of the population falls. In some parts of the world, such as the heavily

3、fished Sea of Japan, the decrease is as high as 35 percent. Thats a loss of more than one in every three fish.Researchers examined changes in 235 populations of fish and shellfish between 1930 and 2010. Those fish populations spread far apart across 38 ocean regions. Temperature changes vary from on

4、e ocean site to another. But on average over that time, Earths seasurface temperatures have risen by about half a degree Celsius.On average, that warming has caused the sustainable catch to drop by 4.1 percent, the study found. About 8 percent of the fish and shellfish populations the team studied s

5、aw losses as a result of the ocean warming. However, about 4 percent of some populations increased. Thats because certain species have thrived in warmer waters. One example is a kind of black sea fish. It lives along the northeastern US. coast. As warming continues, these fish will reproduce faster

6、until they reach their limit.About 3.2 billion people worldwide rely on seafood as a source of food. That means its urgent for commercial fishing fleets and regulators to consider how climate change is affecting the health of all of those fish in the sea.【解题导语】研究发现，随着气候变化导致海洋升温，世界上可持续捕获的鱼类和水生有壳动物在不断

7、减少，这在一定程度上影响了渔业的产量。1What does the new study discover?AOverfishing is to blame for fish health.BWarming seas cause fewer fish and shellfish.CSeafood matters to peoples health worldwide.DThe living regions of fish and shellfish are different.B解析：细节理解题。根据第一段中的“A new study finds that warming seas over t

15、ase, climate change and other reasons have caused their population to drop sharply. In a new study published in the journal BioScience, a team of scientists from various institutions claims that turtles are one of the most threatened among the major vertebrate(脊椎动物) groups.“This could，” the authors

16、say, “have serious consequences for the ecology.” Turtles contribute to the health of many environments, including desert, wetland, freshwater and marine ecosystems, and the decline may lead to bad effects on other species, including humans, they explain. Whit Gibbons, senior author and professor at

17、 the University of Georgias Savannah River Ecology Laboratory, says in a statement that the intention of the study is to inform people about the vital ecological roles of turtles.One of the important qualities of turtles is how diverse they are when it comes to food. This allows them to have a major

18、 impact on food webs of their homes all over the world. In some areas, the density(密度) of the turtle population makes them an important part of the ecosystem. With their gathering, other species that feed on them and their eggs are sure to have a large pool of food.For plants, turtles are also extre

19、mely important as they distribute the seeds of many plant species. When they eat, some seeds are not destroyed by the digestive process and instead make their way out of the animals body. Some turtles are the main dispersal(传播) agents of certain plants and their seeds.These are only a few yet very v
