B (2023·重庆高一期末) A trip to Venice—the poster child for tourism—will now leave your wallet even emptier.Earlier this year，the city announced that anyone who enters Venice and doesn’t stay overnight is set to pay a fee ranging from 3 to 10 euros(about 21 to 70 yuan)，depending on factors such as advance booking and whether it’s peak season or if the city is very crowded.This rule will come into effect in next January. According to The Associated Press，as mass tourism gained popularity in Venice in the mid­1960s，the number of visitors increased year by year.In 2019，there were some 19 million day­trippers who visited the city. As more visitors come to enjoy the charm of the distinctive Italian city，lots of Venetian residents have been forced to leave their homes.According to CNN，due to congestion and the soaring costs of delivering food and other goods in careless Venice，around 70 percent of Venetian residents have left the city in the past 70 years. The government hopes the new rule could help to regulate tourism in the city and “find a balance between Venetian residents and long­term and short­term visitors”，as noted by AP.The money they collect will be used to clean up waste and maintain the heritage of the city. Local Marco Malafante，who manages luxury vacation rentals in the city，also expressed his approval for the move.“As a Venetian I often found myself stuck in crowded lanes.Venice is engulfed by tourists and we have to reduce the day­trippers in favor of a more qualified，let’s call it ‘luxury’ tourism，” Malafante told CNN.But a Venetian gondolier，simply called Cuba，was worried and thought the government moves would “commercialize” the city and disrupt the lives of ordinary people.“Entering Venice will be like entering a museum.I don’t think the measure will help the problem of transforming Venice into a Disneyland，with fake glass shops and piazza sellers replacing the old artisan shops，” Cuba told CNN. 4．Which one of the followings is NOT a factor that influences the future entrance fee of Venice? A．The number of tourists. B．Bookings ahead of arrivals. C．The water conditions of Venice. D．Whether Venice is crowded or not. 5．What can we learn about Venice from the second and the third paragraphs? A．Tourism has greatly benefited the city as well as its local citizens. B．A total of 19 million tourists visited Venice from 1960s to 2019. C．The high delivery fees of goods in Venice make life there expensive. D．About 30% of Venetian residents are thinking about leaving the city. 6．What’s the Venetian gondolier Cuba’s attitude toward the new policy? A．Doubtful. B．Neutral. C．Uncaring. D．Supportive. 7．What is the best title for this passage? A．Will Venice Lose Its Charm? B．Venice—the Italian Water City that You Must Visit C．A New Policy that Might Ruin the Water City—Venice D．Visitors Will Pay for Day­trips in Venice C (2022·广东深圳高一期中) Being highly connected to a strong social network has its benefits.Now a new study is showing the same goes for trees，thanks to their underground neighbors.The study is the first to show that the growth of adult trees is linked to their participation in fungal(真菌) networks living in the forest soil.Though past research has focused on young trees，these findings give new insight into the importance of fungal networks to older trees—which are more environmentally beneficial for functions like capturing carbon. “Large trees make up the main part of the forest，so they drive what the forest is doing，” said researcher Joseph Birch，who led the study.When they live in the forest soil，fungal networks act as a sort of highway，allowing water，nutrients and compounds to flow back and forth among the trees.The network also helps nutrients flow to resource­limited trees like family units that support one another in times of stress. Cores taken from 350 Douglas firs(花旗松) showed that annual tree ring growth was related to the extent of fungal connections a tree had with other trees.They had much higher growth than those that had only a few connections.The research also showed that trees with more connections to many unique fungi had much greater growth than those with only one or two connections.“If you have this network that is helping trees grow faster，that helps capture more carbon year after year.These networks may help trees grow more steadily even as conditions become more stressful，and could even help protect them against death，” said Birch. Birch hopes his findings lead to further studies in different kinds of forests in other geographical areas，because it’s likely that the connections among trees change from year to year.He said，“Knowing whether fungal networks are operating the same way in other tree species could inform how we reforest areas after harvesting them，and inform how we plant trees to preserve these networks.” 8．In what way do the new findings differ from the previous ones? A．They confirm the benefits of fungal networks. B．They demonstrate a new way to capture carbon. C．They clarify misunderstandings of fungal networks. D．They reveal the value of fungal networks to adult trees. 9．How do fungal networks help trees? A．By fighting against diseases. B．By bettering forest soil conditions. C．By maintaining the balance of resources. D．By acting as the center of family units. 10．What does the underlined “those” refer to in paragraph 3? A．Douglas firs. B．Tree rings. C．Fungal networks. D．Cores from Douglas firs. 11．What can be inferred from what Joseph Birch has put? A．The fungal networks support one another in times of stress. B．The fungal networks enable us to know more about reforestation. C．The findings can apply to different kinds of forests in other geographical areas. D．The fungal networks will help trees grow more steadily if conditions become more stressful. Ⅱ.七选五 (2023·广东广州五中高一期末) If you’re looking for a reason to care about tree loss，the nation’s latest heatwaves might be it.Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. 1 .A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five­year period.There are many reasons why our tree cover is decreasing.But the one way that humans can control tree loss is through sensible development.So how can you help stop tree loss? Protect what you have. 2 .We pay for our houses，and so we know that we must maintain them.But because we don’t pay for nature，we often feel we don’t need to protect it.That’s not necessarily true. 3 .If they’re small enough，do it yourself or hire a company which can cut off branches that need to be removed.The risk of branches damaging your house is lowered when there’s tree upkeep(保养)． Notice when your trees may be in trouble.Often，you can observe when something’s wrong，such as when branches are losing leaves and breaking or when mushrooms are growing at the base or on the trees. 4 ，or you can contact your local agricultural office for advice. Don’t remove old trees if it’s not necessary. 5 .It takes a long time for big trees to reach that size.And once they’re established，they can live a long time.But getting rid of a big tree and saying “we’ll plant another tree” isn’t always the answer.There’s no guarantee that small trees will survive and they take a very long time to grow. A．But tree cover in the US cities is reducing B．Cut off the dead branches out of your trees C．Educate yourself about trees and get involved D．Instead，try taking actions like removing branches E．You can dig it up and plant a new tree where you like F．The first step is caring for the trees on your own property G．You can hire an expert to assess the health of your trees annually Ⅰ. 1．C　[细节理解题。根据Highlights部分的第一条“Private Guided Tour for photography lovers”可知，这项旅游适合喜欢摄影的人。故选C项。] 2．D　[推理判断题。根据Itinerary部分的第三段可知，2号观景台是欣赏美景的完美去处，并且也留足了拍照时间，可推知2号观景台是游客的必去之地。故选D项。] 3．B　[写作意图题。根据文章标题The Longji Rice Terraces Day Tour并通读全文可知，文章介绍了龙脊梯田一日游的信息，包括价格、出发时间、亮点描述以及具体的行程安排，故这篇文章的目的是推广这项跟团旅行。故选B项。] 语篇解读　这是一篇新闻报道。文章主要讲述了威尼斯将施行的一项新的旅游举措：对一日游的游客收取入城费用。 4．C　[细节理解题。根据文章第一段第二句可知，具体费用取决于提前预订、是否是旺季(游客的数量)或城市是否拥挤，而选项C并未提及。故选C项。] 5．C　[推理判断题。根据文章第三段第二句可知，由于在威尼斯运送食品和其他商品的费用飙升，已有70%的威尼斯人离开了，由此可推知，高额的运输费用使得在威尼斯的生活昂贵起来。故选C项。] 6．A　[推理判断题。根据文章最后一段最后三句可知，Cuba担心新政并不能帮助解决问题，由此可推知，他持怀疑态度。故选A项。] 7．D　[标题归纳题。通读文章，根据首段可知，威尼斯将对一日游的游客收取入城费用，后文讲述了采取这一措施的原因和人们对此的态度。故选D项。] 语篇解读　这是一篇说明文。一项新研究发现，森林土壤中的真菌网络给树木的生长提供了有利的条件。 8．D　[细节理解题。根据第一段最后一句可知，新的研究关注成年树木，以往研究关注的是幼树。所以新发现与之前的不同之处在于其揭示了真菌网络对成年树木的价值。故选D。] 9．C　[细节理解题。根据第二段的“When they live in the forest soil，fungal networks act as...support one another in times of stress.”可知，真菌网络通过维持资源平衡的方式来帮助树木。故选C。] 10．A　[代词指代题。根据第三段前两句可知，本段以道格拉斯花旗松为例，说明年轮生长和树木之间的真菌联系程度有关。由此猜测，those指代上文提到的“道格拉斯花旗松”。故选A。] 11．B　[推理判断题。根据最后一段最后一句Joseph Birch的话可知，研究真菌网络可以启发我们在采伐后如何重新造林。由此推知Joseph Birch的话表明，真菌网络使我们能够更了解植树造林。故选B。] Ⅱ.1.A　2.F　3.B　4.G　5.D 1 / 9 学科网（北京）股份有限公司 $$ Unit 6 Period 1 Starting out & Understanding ideas分层练习 基础达标 01 能力提升 02 拓展培优 03 Ⅰ.默写重点单词(共30空；每空1.5分，满分45分) 1．____________ v．包，裹 2．____________ n．(冰或水等的)一大片；一张(纸)；被单；床单 3．____________ n．朝代 4．____________ adv.因此，由此 5．____________ adj.浅的 6．____________ n．材料 7．____________ n．障碍，壁垒 8．____________ n．结构，构造，组织vt.系统安排；精心组织 9．____________ adj.活的，活着的 n．生活；生计 10．____________ adj.宏伟的，壮丽的 11．____________ n．霜→____________ adj.严寒的；结霜的 12．____________ n．地区，区域→____________ adj.地区的，区域的 13．____________ v．设计；计划；意欲 n．设计(方案)；意图→____________ n．设计者 14．____________ n．农业→____________ adj.农业(劳动/生产)的 15．____________ v．以……替换，更换；取代；把……放回原处→____________ n．替换(的人/物) 16．____________ n．优先处理的事，当务之急→____________ adj.先前的；优先的 17．____________ n．美，美丽；美人；美好的东西→____________ adj.漂亮的；美丽的→________ v．美化；使更美丽 Ⅱ.词形变化填空(共5小题；每题3分，满分15分) 1．The book written by a professor raised public awareness of the danger of pollution and the ____________(harm) effects of chemicals on humans. 2．When it comes to ____________，____________ in the developed countries ____________ the most energy in the world.(consume) 3．As is known to us all，a ____________ society means that human beings can live in __________ with each other.(harmony) 4．Knowing the symptoms(症状) of heart attack is of great importance to the elderly，which will have a positive effect on its ____________(prevent)． 5．The photographer ____________(narrow) escaped being killed in the serious car accident.
