2025届高考英语模拟预测卷(全国甲卷) 一.阅读理解(共4小题) 1.(2025 达州二模) Last December,researchers at the National Ignition Facility(NIF) had made a breakthrough in fusion(核聚变) energy,the same chemical process that powers the stars and our sun.They had succeeded in producing the first laboratory fusion reaction that produces more energy than it takes to cause the reaction.It made headlines around the world. At extremely high temperatures and pressure,the atoms break into their components—nuclei(原子核) and electrons.This kind of positive nuclei and negative electrons is referred to as plasma(等离子体).It is considered the fourth state of matter,the other three being solid,liquid and gas.Fusion is a process that takes place in the plasma state.The process of fusion produces a huge amount of energy which,in turn,causes further fusion reactions. Our sun is incredibly efficient in producing fusion energy;its huge mass creates the pressure and temperatures needed to keep the reaction going.Earth can't recreate the high pressure and temperature conditions of the sun,so scientists must find techniques in laboratories to start the reaction. The NIF experiment successfully proved that fusion isn't just a theoretical concept:we are able to create an cnergy source that is self﹣sustaining.Fusion also has the advantage﹣it does not cause radioactive waste. However,despite billions of dollars of government funding put into fusion research,we are still decades away from fusion﹣produced electricity.Humans have produced fusion reactions in the past,with nuclear bombs.But in bombs,the energy is released too quickly.Scientists will need to figure out how to release energy in a controlled and consistent manner for regular use. Even if we can overcome challenges in the development,will fusion be able to compete with solar and wind power for cost and availability?The future of fusion may not be clear at the moment,but it is truly brilliant for science and society to see the power of the sun come to life in a lab setting. (1)What facts have we learned about the first laboratory fusion reaction?    A.It was a big success. B.It escaped public attention. C.It produced less energy than expected. D.It introduced the fourth state of matter. (2)What is a big advantage of fusion energy?    A.It depends on the sun. B.It can be clean energy. C.It is an unexpected energy source. D.It works under normal conditions. (3)What can be implied about producing fusion energy in paragraph 5?    A.It faces some challenges now. B.It isn't supported by governments. C.It may cause very dangerous consequences. D.It cannot compete with solar and wind power. (4)Which statement would the author most likely agree with?    A.The future of fusion is clear and bright. B.Fusion energy will be the main energy one day. C.The present achievements in fusion energy are remarkable. D.The experimental techniques are essential to producing fusion ener ... ...
