B.The loss of natural habitats. C.The harm of nuclear radiation. D.The thickening of the ozone layer. 2.How did Koski’s team get their findings？（　　） A.By collecting photographs of flowers from different species. B.By analyzing how levels of UV pigments change over time. C.By collecting abundant samples from various species. D.By analyzing historic local temperature and ozone level data. 3.What can we learn about the change in pigments？（　　） A.It exists in flowers with exposed pollen only. B.It responds to temperatures and sea levels. C.It remains the same regardless of species. D.It varies depending on the flowers structure. 4.What is Koski’s attitude toward the change in flowers color？（　　） A.Concerned. B.Indifferent. C.Unclear. D.Optimistic. B 　　As we all know， trees are always stationary： they stay more or less where you plant them， and no one worries about finding a tree wandering around a park or back yard. 　　However， there is one special exception， some say： the so-called walking palm tree （棕榈树） was found in the rainforests of Central and South America.Many people believe it can really walk around.This is because of its unusual root system： while most trees have one trunk， the palm breaks into many smaller roots a few feet off the ground， giving it the appearance of many little legs. 　　The amazing walking ability of the palm tree has always been told by rainforest guides to tourists for years， and appears in many sources of documents as an amazing plant adaptation.As journalist Sherry Seethaler writes in her book Curious Folks Ask 2： “Screen writers searching for the perfect B-movie （小成本电影） plant hero could take inspiration from the walking palm.The tree slowly walks from shade to sunlight by growing new roots toward the light.” 　　A tree that walks in search of the sun is a fascinating， strange story.And it’s not true either； the tree is real enough， but it doesn’t walk.It sits where it began to grow， not moving except under the force of wind or an axe. 　　Biologist Gerardo Avalos is one of the world’s top experts on the palm tree.His analysis of the plant and its roots shows that the walking tree can’t walk because its roots don’t move.A few roots on one side or another may die off， but the trunk itself remains， well， rooted to the spot. 　　“My paper proves that the belief of the walking palm is just a myth，” Avalos said.“Thinking that a palm tree could actually track the sunlight changes by moving slowly over the forest floor ... is a myth that tourist guides find amusing to tell visitors to the rainforest.” 5.What is the reason for no worries about wandering trees？（　　） A.Trees are not always standing. B.Trees are not always moving. C.Trees are not always growing. D.Trees are not always dying. 6.Why do people think the palm tree can walk around？（　　） A.It has no roots underground. B.It appears to have several trunks. C.It grows a few feet off the ground. D.It appears to have many little legs. 7.What can we learn about the palm tree from the passage？（　　） A.It wanders around the rainforest at night. B.It grows in Central and North America. C.It is a popular attraction among visitors. D.It grows well in the shade of the rainforests. 8.What does biologist Gerardo Avalos believe？（　　） A.The palm tree cannot actually walk at all. B.The palm tree can move its roots. C.The palm tree can track the sunlight. D.The palm tree cannot keep its trunk growing. Ⅱ.阅读七选五 　　No matter where you go， you’ll notice something strange about trees — the fact that their bottoms are painted white.Generally speaking， the purpose of whitewashing is to protect trees from heat and insects.9.（　　）.Let’s check them out！ 　　Blocking the sun 　　You might sometimes notice that some tree trunks’ surfaces get dry and crack easily.10.（　　）.Simply put， they are exposed to the burning sun and the temperatures change wildly between day and night.Fortunately， painting a tree’s trunk white is similar to adding sunscreen， which helps block the sun. 　　Heat protection 　　11.（　　）.White paint reflects the heat and allows trees to spend more time on transpiration （蒸腾） and growing their fruits.Additionally， when trees are cooler， they have less stress， which makes their stomata （气孔） stay open a bit longer for the exchange of gases. 　　Defending against pests 　　More often than not， a tree’s surface will crack， allowing insects to creep inside.12.（　　）.Therefore， people whitewash trees using latex paint and water， which prevents insects from climbing up trees and entering inside through the cracks. 　　13.（　　） 　　Last but not least， the surface of trees is painted white to make them more visible， specifically for those on the side of the road.Why is that important？ Because accidents involving trees are extremely common， especially during the night， when drivers can not see them much more clearly. A.Stopping accidents B.Improving visibility C.Whitewashing is a good way to solve the problem D.The cause of this phenomenon has already been found E.Whitewashing helps young trees remain cool in spring F.However， there’re many other reasons for whitewashing trees G.Bacteria will feed on the tree’s inner parts， eventually killing it Ⅲ.应用文写作 　　假定你是校学生会主席李华，你校即将举办“美丽校园”短视频大赛。请你用英文写一份邀请函，请国际班的学生参加比赛，内容包括： 　　（1）比赛目的；（2）视频要求。 注意：（1）写作词数应为80个左右；（2）请按如下格式作答。 Dear students， 　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　 Yours sincerely， Li Hua 6 / 6 学科网（北京）股份有限公司 $ Section Ⅲ　Developing ideas 基础知识自测 维度一 1.roots　2.myths　3.legends　4.centimetres　5.linked 6.primitive　7.characteristic　8.worldwide　9.detect 维度二 1.amazing　2.Surprisingly　3.similarly　4.injuries 5.belief　6.appearance　7.communication 8.cultural　9.detection　10.attraction 维度三 1.With time going by　2.It’s reported 3.so that they could catch the first bus 4.is very similar to　5.communicate with 6.was to blame for　7.link their bank cards to 8.drive away　9.In the end　10.in particular 维度四 1.①C　②B　③A　2.n.根源，起因　3.n.图例 素养能力提升 Ⅰ. 语篇解读：本文是一篇说明文。最新研究表明，为了适应气候变化，一些花的颜色正在变深。 1.A　细节理解题。根据第一段可知，为了适应气候变化，一些花朵正在加深颜色以保护自己免受太阳辐射，所以花朵颜色变化的原因是气候危机的影响。 2.B　细节理解题。根据第三段可知，研究团队将紫外线敏感相机拍摄的花瓣照片与采摘植物时的当地历史温度和臭氧水平数据配对，分析紫外线色素水平如何随时间变化，从而得出研究结果。 3.D　细节理解题。根据第四段第一句可知，色素的变化因物种而异，是花朵结构导致的，即色素变化取决于花朵的结构。 4.A　推理判断题。根据最后一段中Koski说的话可知，Koski 认为花朵颜色变化对植物繁殖有负面影响，说明他对花朵颜色变化持担忧态度。 语篇解读：本文是一篇说明文。许多人都相信中美洲和南美洲的热带雨林中的棕榈树会行走，而相关研究发现这些树实际上并不能行走。 5.B　细节理解题。根据第一段内容可知，人们不用担心树会四处游荡，是因为树一直是静止的，即不会四处移动。 6.D　细节理解题。根据第二段最后一句可知，人们认为棕榈树能行走是因为它的根系不同寻常，在离地面几英尺的地方分成许多小根，看起来像许多小腿。 7.C　推理判断题。根据第三段第一句可知，多年来雨林导游一直向游客讲述棕榈树惊人的 “行走” 能力，这表明它在游客中是一个很受欢迎的景点。 8.A　细节理解题。根据倒数第二段可知，生物学家 Gerardo Avalos 认为棕榈树实际上根本不能行走，因为它的根不会移动。 Ⅱ. 语篇解读：本文是一篇说明文。文章解释了树木底部被粉刷成白色的原因。 9.F　10.D　11.E　12.G　13.B　 Ⅲ.
