BUnusually bright light in the sky that appeared suddenly last June has got astronomers in great excitement.After months of study,they still aren't sure what the object-universally referred to as the "Cow"-is.Whateverit is,says astronomer Liliana Rivera Sandoval of Texas Tech University in Lubbock,"It's super strange."The Cow first appeared in telescope observations on 16 June 2018,in what turned out to be a small galaxy()about 200 million light years away."When we saw that we thought,let's get on this,says Daniel Perley,anastronomer at Liverpool John Moores University.The early observations confirmed the Cow was truly strange.It didn't show the obvious changes in its lightoutput that an exploding star would make.Sandoval says as soon as she and her colleagues knew the Cow wastruly distant,they requested time on NASA's Neil Gehrels Swift Observatory to see what the Cow was doing inX-rays.Although the X-ray brightness varied over the early weeks,"the spectrum()didn't change,which isvery unusual,"she notes.After 3 weeks,the X-ray signal began to vary more wildly while also dropping off inbrightness.Many astronomers agree that the long and steady duration of the event means that it was powered after aninitial explosion by some form of central engine.But what that engine may be is also far from clear.Some arguethat it could be a very unusual star whose central part has collapsed()inward after it exploded.Others say itis a tidal disruption event-a star being torn apart by a black hole.But that usually requires the supermassiveblack hole in the center of a galaxy,and the Cow is situated in its galaxy's arm.So,some say,it could be a tidaldisruption event generated by an intermediate mass black hole,although evidence for the existence of suchsmaller black holes remains controversial."All explanations have problems,Sandoval says,"I hope there aremore Cows.”4.What is astronomers'main concern about the Cow?A.What it is.B.How it forms.C.When it appears.D.Where it is from.5.What did Sandoval and her team hope to find out about the Cow in X-rays at NASA?A.What the Cow was doing.B.How far the Cow is from the earth.C.Whether the Cow is an exploding star.D.Why the X-ray signals varied wildly.6.What do Sandoval's words at the end of the text probably mean?A.The research results help little.B.More Cows will appear.C.Extra attention should be paid to the Cow.D.More information is needed.7.What is the best title for the text?A.A Strange Explosion in Deep SpaceB.An Interesting Observation of NASAC.A Wide Range of Changes in the GalaxiesD.A Great Achievement in Astronomy【语篇导读】本文是一篇说明文。文章主要讲了一个新出现在太空中的发光体引起天文学家的极大关注，但对它的观察结论却难达共识。4.A推理判断题。根据第一段After months of study,they still aren't sure what the object-一universallyreferred to as the“Cow”一is.可知天文学家们首要关心的是“Cow”是什么。5.A细节理解题。根据第三段Sandoval says as soon as she and her colleagues knew the Cow was truly distant,they requested time on NASA's Neil Gehrels Swift Observatory to see what the Cow was doing in X-rays.,Sandoval和她的团队希望通过NASA的X射线发现Cow在做什么。6.D推理判断题。根据最后一段“All explanations have problems,”Sandoval says,“I hope there are moreC0ws.”可知，目前观测C0w得出的结论都有问题，由此推断，她希望出现更多的Cow提供更多的信息。7.A标题归纳题。根据第一段Unusually bright light in the sky that appeared suddenly last June has gotastronomers in great excitement,.,.“It's super strange,”并结合全文内容可知，这篇文章主要讲了一个新出现在太空中的发光体引起天文学家的极大关注，但对它的观察结论却难达共识。全文“theC0w”这一主题贯穿始终，A项“深空的奇怪爆炸”最适合作为文章标题。

第一部分阅读理解（共两节，满分40分）】第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。AUnique Australian Wildlife ExperiencesDive with whale sharksAbout halfway up the West Australian coastline,Ningaloo Marine Park is the only place on the planet wherelarge numbers of whale sharks are known to reliably visit so close to land.Join a one-day marine tour in holidaytowns of Exmouth or Coral Bay from April to July and dive alongside these 14-metre harmless fish.Play with a platypusThe native Australian platypus is well-known for its shyness,but in a remote rainforest you can dive withthem.In Queensland's Mackay region,you'll get a very special experience indeed.Dives take place at dawn anddusk,when these beautiful animals are most active.If you'd rather not get wet,then head to the HealesvilleSanctuary in Badger Creek.Spot Australian dingoesNot quite a dog,and definitely not a wolf-the Australian dingo is a wild animal and an Australian symbol.You can find them at the Australian Reptile Park and at most zoos,but if your heart is set on seeing them in thewild,your best bet is to visit Queensland's Fraser Island.Enjoy the Penguin ParadeLocated just a 90-minute drive south of Melbourne,Phillip Island is a great place with different varieties ofwildlife.One of the area's most popular events,the Penguin Parade allows visitors to catch a sight of the island'snative little penguins as they come back ashore after a day of fishing.Head to Summerland Beach for a 180-degreeviewing of the parade.1.What do we know about whale sharks?A.They live close to land.B.They are large in size.C.They are dangerous fish.D.They are unique to Australia.2.When can you dive with platypus?A.Right at noon.B.Around midnight.C.Early in the afternoon.D.Early in the morning.3.What is the best destination for seeing dingoes in the wild?A.Queensland's Mackay region.B.Australian Reptile Park.C.Queensland's Fraser Island.D.Summerland Beach.【语篇导读】本文是一篇应用文。文章主要介绍了四种独特的澳大利亚野生动物之旅。l.B细节理解题。根据第一段最后一句中的dive alongside these 14-metre harmless fish可知，鲸鲨是一种无害的大型鱼类。2.D钿节理解题。根据第二段Dives take place at dawn and dusk,when these beautiful animals are most active.可知，潜水的时间是鸭嘴兽最活跃的两个时间段一黎明和黄昏时分，只有D选项属于这两个时间段。3.C细节理解题。根据第三段if your heart is set on seeing them in the wild,your best bet is to visitQueensland's Fraser Island可知，如果想要看到野生的澳洲野犬，最好的选择就是去Queensland's Fraser Island。
