For one thing，renewables supplied only 23 per cent of electricity during this coal-free period，while 45 per cent came from natural gas. In the past decade，the country has gone from getting a third of its electricity from coal to obtaining more than a third from renewables like onshore wind on average. Australia now gets 11 per cent of its electricity from “renewable” biomass(生物质能燃料)，much of it using imported wood. But forest campaigners say swapping coal for wood isn't truly renewable and is actually doing huge damage to the environment. For another，Australia is off-track when it comes to meeting its long-term targets for cutting greenhouse gas emissions(排放).Producing electricity without burning fossil fuels is relatively easy. But it is much harder to heat homes，to make cement and steel，to grow food and to power cars，ships and planes without producing any greenhouse gases. In view of this，we should handle the energy and climate crises at the same time by finding climate-friendly alternatives to coal. Australia has now stopped the financial aid that drove its renewables revolution. So growth in renewable energy is expected to come to a stop in a decade. The global renewables revolution seems to be following the same trend. The International Energy Agency(IEA) recently announced that the world added 180 gigawatts (千兆瓦) of solar，wind，hydropower and bioenergy in 2018，the same as in 2017.But IEA said we must add 300 gigawatts a year to have a chance of limiting global warming to under 2 ℃ by 2100. So we should cheer the end of coal，but continue to worry about how it will be replaced. [语篇解读]　本文是一篇说明文。我们应该为澳大利亚“无煤周”感到兴奋吗？虽然一些人将其视为该国的环保举措，但从宏观角度上看它却并不是那么鼓舞人心。 2 3 1 4 1．In the“coal-free week”，what did Australia use most to make electricity? A．Natural gas.　　　　　 B．Onshore wind. C．Biomass. D．Wood. 答案：A 2 3 1 4 细节理解题。根据第一段中的“renewables supplied only 23 per cent of ...while 45 per cent came from natural gas”可知，在“无煤周”，45%的电力来自天然气，故A项正确。 2 3 1 4 2．What can be inferred about the reduction of greenhouse gas emissions in paragraph 2? A．Positive results are tracked. B．Long-term goals are ambitious. C．Additional efforts are required. D．Climate change is unavoidable. 答案：C 2 3 1 4 推理判断题。根据第二段中的“Australia is off-track when it comes to meeting its long-term targets for cutting greenhouse gas emissions”并结合本段的陈述可以推断，在减少温室气体排放问题上，澳大利亚还需要付出更多努力，故C项正确。 2 3 1 4 3．What can we learn about renewable energy in paragraph 3? A．It ought to be replaced. B．It will see an adequate increase. C．It starts a revolution in Australia. D．It needs constant financial aid. 答案：D 2 3 1 4 推理判断题。根据第三段中的“Australia has now stopped the financial aid ...come to a stop in a decade.”可以推知，可再生能源的变革需要持续的资金援助，故D项正确。 2 3 1 4 4．What is the author's attitude towards the coal-free week? A．Skeptical. B．Optimistic. C．Thrilled. D．Ambiguous. 答案：A 2 3 1 4 观点态度题。根据第一段中的“Should we be thrilled that ...the bigger picture is less encouraging.”可知，作者对“无煤周”持怀疑态度，故A项正确。 B (2023·江苏南京统考)New bioplastics are being made in laboratories from straw，wood chips and food waste，with researchers aiming to replace oil as the source of the world's plastic. The new approaches include genetically modifying bacteria to eat wood and produce useful chemicals. But the bioplastics are currently significantly more expensive to make than fossil fuel-based plastics. Land and seas around the world，from high mountains to deep oceans，have become polluted with plastic，prompting major public concern. The world has produced about 8bn tonnes of plastic since the 1950s and demand is still rising. While some waste plastic is recycled，much of it is burnt to produce electricity，resulting in carbon emissions that drive climate change. In contrast to plastic made from oil，plastics made from plant-based materials only release the carbon the plants absorb from the air as they grow. Bioplastics will also give more options for products that biodegrade in the environment，although they can be made very long-lasting if required. “Plastics are an incredible enhancement to our daily lives，”said Paul Mines，CEO of Biome Technologies in the UK，which has spent￡ 5m in the last five years on bioplastics research. “But we can't go on using fossil fuel-based materials. About 6%－7% of every barrel of oil is used to make plastics.” Using plant materials is feasible，said Professor Simon，at the University of York. Replacing half of the nation's plastic bottles could be done by using just 3% of the sugar beet crop，5%of wheat straw or 2.5% of food waste，he said. Currently，just a few thousand tonnes of bioplastics are used in the UK each year，compared to millions of tonnes of conventional plastic. Mines said this could rise to about 20，000 tonnes in the next five years. [语篇解读]　本文是一篇说明文。科学家们正在试验用秸秆、木屑和食物垃圾制造一种新型生物塑料。与传统的化石燃料塑料相比，它更具有环保性。 5 6 7 8 5．Why are high mountains and deep oceans mentioned in paragraph 3? A．To display the range of plastic waste. B．To show the widespread use of plastic. C．To stress the increasing demand for plastic. D．To raise awareness of ocean protection. 答案：A 5 6 7 8 推理判断题。根据第三段中的“Land and seas around the world，from high mountains to deep oceans，have become polluted with plastic”可知，世界各地的陆地和海洋，从高山到深海，都受到了塑料的污染。由此可推知，作者提到高山和深海主要是为了展示塑料垃圾的范围，故选A。 5 6 7 8 6．What is one advantage of bioplastics over fossil fuel-based plastics? A．Producing electricity. B．Being eco-friendly. C．Driving climate change. D．Biodegrading other plastics. 答案：B 5 6 7 8 细节理解题。根据第四段中的“While some waste plastic is recycled ...from the air as they grow.”可知，传统的化石燃料塑料会产生很多的碳排放，而新型的生物塑料只释放被植物吸收的碳。由此可知，与化石燃料塑料相比，生物塑料的一个优势是有利于环保，故选B。 5 6 7 8 7．What does the underlined word “feasible” mean in paragraph 6? A．Possible. B．Troublesome. C．Original. D．Costly. 答案：A 5 6 7 8 词义猜测题。根据画线词后的“Replacing half of the nation's ...2.5% of food waste”可知，仅用3%的甜菜作物、5%的小麦秸秆或者2.5%的食物垃圾就可以替换全国一半的塑料瓶。由此可推知，使用植物材料是可行的，故画线词的意思与A项最为接近。 5 6 7 8 8．What is the main idea of the text? A．Plastics are necessary in daily life. B．Oil is the source of the world's plastic. C．Bioplastic making is a promising industry. D．Scientists are researching bioplastic making. 答案：D 5 6 7 8 主旨大意题。通读全文尤其是第一段内容可知，本文主要讲述了科学家正在研究一种用秸秆、木屑和食物垃圾制造的新型生物塑料。故选D。 Ⅱ.完形填空 (2023·广东惠州调研)One summer day，Bella，our pet dog，was in the bushes in our backyard making all sorts of noises.Our 11-year-old daughter，Kaitlin，discovered her sniffing and pawing at a 1 ，where several caterpillars (毛毛虫) chewed.
