ACoronavirus (冠状病毒) has infected more than 170,000 people across the world, and the virus is expected to peak in the UK in the coming weeks. Professor Chris Whitty said on March 12 that he expects the UK would reach the peak of its coronavirus outbreak in about 10 to 14 weeks.The NHS is currently advising you to self-isolate for seven days if you have symptoms of coronavirus, like a high temperature, or a new continuous cough. If you have travelled to a badly affected area, or have been in contact with someone with the disease, you will also need to self-isolate. Staying at home will help to control the spread of the virus.When you self-isolate, you need to stay away from public places. This means you cannot take your pets out for walks in public places. With more time indoors, its also a good idea to plan how you can keep your pet occupied while self-isolating. If youve been diagnosed with coronavirus, you should inform your local health protection team that there is a pet in the household. They will touch with the relevant animal health authorities. If your pet shows signs of ill health, please do not take them to the vet. Contact your local health protection team for advice.The RSPCA have also issued tips for keeping your pets and family safe while self-isolating. If you havent tested positive or been asked to self-isolate then continue to interact with your pets as normal but adopt good hygiene (卫生) practices including washing hands thoroughly with soap and water before and after touching them, their food, toys and bedding. Avoid being kissed or licked and sharing food with your pet. Ensure you have extra supplies of pet food and medication in case of self-isolation. Speak to your vet or doctor for more advice.1.

Some 11m hectares of the Lucky Country have gone up in smoke since September, almost the same area as Bulgaria (保加利亚). So far at least 26 people are known to have lost their lives, over 2,300 homes have been destroyed and over half a billion animals have been burned alive or choked to death. But numbers tell only part of the story.You might think that Australia is particularly vulnerable to forest fires. But that would be a mistake. Many other countries share the same conditions that have set Australia ablaze, physically and politically, including similar terrain and a leadership that has yet to wake up fully to the new reality that climate change is creating. Worldwide, fire seasons are getting longer and more damaging. As a result, the lessons from Australias tragedy are important. One is that climate change is making fire more likely. It is true that forest fires are a long-standing part of some territories ecology. But as the world gets hotter and drier, their incidence and severity are rising. Another lesson is that as fires get worse the old ways of assessing and containing them have become obsolete. Unlikely as it may seem, Australias fire-planning is ahead of most of the worldsit carries out preventive burns, for example, and its planning codes seek to limit fire risks. Nonetheless this system, and a heroic voluntary firefighting force, has been overwhelmed. Attention must now turn to how to live with fires. In some places, that will mean building structures that can resist the flames. Other regions may no longer be suitable for human habitation. The last lesson is that, as the costs of climate change stop being just about abstract temperature forecasts and start being something you can smell in your nose, the politics surrounding it will change, too.1. How many people have probably died in the recent forest fire in Australia?A. 28.B. 25.C. 18.D. 10.2. Which of the following is NOT the main reason of the forest fire in Australia?A. Terrain.B. Political policy.C. Climate change.D. Lack of firemen.3. What is the meaning of the underlined word in Paragraph 3?A. Advanced.B. Dangerous.C.Outdated.D. Popular.4. What is the passage going to talk about next?A. Regional measures. B. Political change.C. Establishment of anti-fire forces. D. Safer house building.CBetelgeuse (猎户座) is a red supergiant star in Orion, a prominent constellation (星座) that spans the celestial equator. It is one of the brightest objects in the night sky, easily visible to the naked eye. It has around ten times the mass of the sun, and if it were at the centre of the solar system its outer edge would stretch beyond the orbit of Mars. Betelgeuse shines more brightly than the sun partly because it is bigger and thus has more fuel, but also because it is burning through that fuel faster. As a result, it will die much sooner. The sun is around halfway through its 10bn-year lifespan. Betelgeuses span will be about 10m years, and it is close to the end of that periodperhaps very close. For, in the past few weeks, astronomers have watched it getting precipitously dimmer and that has made them wonder: could this be a signal that Betelgeuses time has come? When a star such as Betelgeuse runs out of fuel the nuclear reactions in its core which keep it shining stop and the heat and outward radiation pressure need to balance the force of gravity trying to pull everything inward. At that point, gravity wins. The core collapses. And the resulting shock wave destroys the star in an explosion called a supernova (超新星) that is temporarily brighter than the rest of Earths home galaxy, the Milky Way, put together.So far, the closest supernova seen since the telescope was invented is SN1987A, spotted more than three decades ago in the Large Magellanic Cloud, a galaxy 160,000 light-years from the Milky Way. But astronomers detected SN1987A only after it had already happened. They have never been able to bring modern instruments to bear on a supernova in the Milky Way itself, and never watched a star in the moments before and during its final explosion.1. What is the feature of Betelgeuse?A. It is a normal-sized star in Orion.B. It is invisible to our naked eyes.C. It will die much sooner than the sun.D. It is at the center of the solar system.2. Why does Betelgeuse shine more brightly than the sun?A. Because it is twice bigger than the sun. B. Because it has more fuel than the sun.C. Because its burning speed is much slower.D. Because it has a longer lifespan than the sun.3. What can we know from Paragraph 2?A. Stars can continue shining with fuel.B. Stars without fuel will explode in the end.C. A supernova is permanently brighter than the rest of galaxy.D. The outward radiation pressure can balance the gravity.4. Where is this article mostly likely from?A. A guide book.B. A novel.C. A diary.D. A science magazine.参考答案A【答案】1-4 ADCC【解析】本文一篇说明文，主要介绍了英国正受新冠病毒的影响，官方就自我隔离期间提出了关于宠物饲养方面的建议。1. 细节理解题。根据第二段的第一句和第二句“.like a high temperature, or a new continuous cough. If you have travelled to a badly affected area, or have been in contact with someone with the disease, you will also need to self-isolate.”可知，B、C、D都符合隔离的条件，A选项未提及，故选A。2. 推理判断题。根据第三段的第四句“.you should inform your local health protection team that there is a pet in the household.”可知，你可以通知当地的卫生保护小组，再结合下文谈到的动物卫生局，可推知，宠物会有专人照顾，故选D。3. 细节理解题。根据第二段最后一句“Staying at home will help to control the spread of the virus.”可知，C选项符合，故选C。4. 概括大意题。通读全文，文章主要介绍了自我隔离期间，有关宠物饲养方面的建议，故选C。B【答案】14 ADCB【解析】本文是一篇说明文，说明了澳大利亚火灾的影响和得到的启示。1. 细节理解题。根据第一段第三句话“So far at least 26 people are known to have lost their lives”可知，至少有26人死于火灾，故选A。2. 细节理解题。根据第二段第三句话“Many other countries share the same conditions that have set Australia ablaze, physically and politically, including similar terrain and a leadership that has yet to wake up fully to the new reality that climate change is creating.”可知，相似的地势、领导人的政策和气候变化都是澳大利亚火灾的主要原因，故选D。3. 词义猜测题。根据划线单词所在句后文列出的其他评估和抵抗火灾的新方法，可知本句表示另一个教训是，随着火灾的恶化，评估和控制火灾的老方法已经“过时了”，审视选项，Outdated最接近，故选C。4. 推理判断题。根据第三段最后一句话“The last lesson is that, as the costs of climate change stop being just about abstract temperature forecasts and start being something you can smell in your nose, the politics surrounding it will change, too.”可知，文章接下来要谈关于应对气候变化政府相对应措施的变化，故选B。C【答案】14 CBBD【解析】本文是一篇说明文，说明超新星的特点及其发展过程。1 .细节理解题。根据第一段第五句“As a result, it will die much sooner.”可知，猎户座能量消耗得更快，也就会比太阳更早消亡，故选C。2. 细节理解题。根据第一段第四句“Betelgeuse shines more brightly than the sun partly because it is bigger and thus has more fuel, but also because it is burning through that fuel faster.”可知，Betelgeuse因为更大，能量更多，燃烧速度更快，所以比太阳更亮，故选B。3. 推理判断题。根据第二段“At that point, gravity wins. The core collapses. And the resulting shock wave destroys the star in an explosion”可知，超新星能源燃尽后，最后在重力的作用下会爆炸，故选B。此题注意排除D项，既然“重力赢了”，就说明外辐射压力最终没能平衡重力，因此D项不符合，需排除。4. 文章来源题。本文是一篇关于猎户座的科学类报道，审视选项，最可能出现在科学杂志中。故选D。
