说明文 青年食物领导者 ★★★ 8 min P48
　　High school students dug deep into their studies this summer， participating in the Youth Leadership Programme of Green Village Initiative (GVI) while also earning college credits from Housatonic Community College (HCC). The new and original partnership between the two organisations allowed students to earn four college credits in Biology and immerse themselves in the lively learning environment of GVI’s Reservoir Community Farm.
Eight students， aged 14—18， participated in the strict eight-week programme. For six days each week， students attended online learning while taking HCC’s Plants and Civilisation Course. The farm served as an outdoor lab for the class， where students learnt about the process of seed to table， food access and sustainability， food deserts， food justice and more.
“Students learn better when they’re getting their hands dirty，” said Ofonime Udo-Okon， manager of GVI’s Youth Leadership Programme. “HCC is setting an example as to what integrated learning can look like.” On Bridgeport’s only urban educational farm， the students， who all either live or attend school in Bridgeport， were transformed into young food leaders. Through their studies and hands-on instruction， each learnt their role in the food system， and how to make a positive change. “I wanted to be in the programme so I can give back to the community，” said Sariah Cohen， a 15-year-old sophomore at Bridgeport’s Central High School. “I like the practice that we provide the community with fresh， inexpensive food.”
GVI’s Youth Leadership programme is rooted in food justice， addressing the reality that low-income people are severely impacted by food insecurity， poor access to nutritious food， and the resulting diet-related illnesses. The programme teaches young people how to take action to remove food barriers and provide access to healthy produce for Bridgeport’s community.
“GVI is a jewel in the city that can sustain our future，” said Robin Avant， HCC’s Dean of Academic Affairs. “Seeing the youth deeply embedded in soil is remarkable. As they grow crops， the students are growing their independent knowledge and experiences， while building agricultural sustainability plans that are critical to food justice.”
语篇解读：本文是一篇说明文。文章主要介绍了美国高中生通过Green Village Initiative与Housatonic社区大学合作项目在农场工作，在学习生物学的同时，成为青年食物领导者。
(　　)4.How does the partnership between GVI and HCC benefit the students
A.It offers students the chance to study abroad.
B.It encourages cooperation among learners.
C.It teaches students abundant knowledge about food insecurity.
D.It combines online learning with hands-on experience.
【解析】 细节理解题。根据第一段中的“The new and original partnership between the two organisations allowed students to earn four college credits in Biology and immerse themselves in the lively learning environment of GVI’s Reservoir Community Farm.”及第二段中的“For six days each week， students attended online learning while taking HCC’s Plants and Civilisation Course.”可知，学生们既可以参加Housatonic社区大学的在线学习课程，也能在GVI的农场进行亲身实践，这是二者合作对学生的好处。
D
(　　)5.What does the underlined sentence in Paragraph 3 imply
A.Students prefer working the land to learning in class.
B.Students need to wash their hands before entering the lab.
C.Active engagement and real-life experience help learning.
D.Working on a farm teaches students important life skills.
【解析】 词句猜测题。根据画线句前面的“The farm served as an outdoor lab for the class， where students learnt about the process of seed to table， food access and sustainability， food deserts， food justice and more.”可知，学生在农场这个户外实验室学到了很多课本外的内容。故此处的getting their hands dirty指的是学生们动手实践，暗示学生通过动手实践(在农场亲身实践的体验)学得更好，即强调动手参与和真实的体验能够增强学习效果，而不应局限于课本上的知识，与选项C“积极参与和真实的体验有助于学习”语义相近。
C
(　　)6.What is the main concern that GVI’s Youth Leadership programme aims to address
A.Discrimination against poor people.
B.Uneven accessibility to healthy food.
C.Research on nutrition-related issues.
D.Income inequality among different jobs.
【解析】 细节理解题。根据第四段中的“GVI’s Youth Leadership Programme is rooted in food justice， addressing the reality that low-income people are severely impacted by food insecurity， poor access to nutritious food， and the resulting diet-related illnesses.”可知，该计划主要关注的是低收入群体获取健康食品的机会不均衡的问题。
B
(　　)7.What is the last paragraph mainly about
A.The far-reaching impact of GVI.
B.The commercial value of GVI.
C.The rapid development of GVI.
D.The extensive popularity of GVI.
【解析】 段落大意题。通读最后一段的内容可知，Robin Avant提到了参加GVI的青年领导力计划的年轻人在农业实践中逐渐获得知识和经验，并指出他们正在构建对食品正义至关重要的农业可持续发展计划。由此可知，本段说明了GVI的意义和产生的深远影响。

说明文 城市农业 ★★★ 8 min P48
　　Urban agriculture， the practice of farming within the restrictions of a city， is becoming increasingly popular and is viewed as a sustainable alternative to big industrial farms. By some estimates， between 20% and 30% of the global urban population engages in some form of urban agriculture. But until recently， its carbon footprint remained understudied.
Using data from 73 low-tech city farms， community gardens and personal plots of land， Newell and his team compared the average carbon emissions of food produced at low-tech urban agriculture sites with those of conventionally grown crops. The team found that because of urban gardens’ relatively low yields， along with the energy used in constructing the planting beds， big-city spuds (马铃薯) were significantly more carbon-intensive than commercially grown ones.
This held true even when the researchers factored in emissions from transporting commercially grown produce to often distant grocery stores. That doesn’t mean that growing vegetables in big cities is totally bad， however. “Urban farming is great， if imperfect，” says Carola Grebitus， a food choice expert. “It can be a powerful tool for job creation and education，” she says， “and a good way to introduce fresh produce to urban ‘food deserts’ where healthy fruits and vegetables are hard to come by.” Community gardens can also provide a place to connect with nature， and the added green space can reduce the risks of heat and flooding.
Conscious of these benefits， Newell’s team highlighted several ways to make urban agriculture more sustainable. One option is to be selective about what crops are grown. For instance， tomatoes grown in the soil of open-air urban plots had a lower carbon intensity than tomatoes grown in conventional greenhouses. Another strategy is to rely on existing constructions. Include old structures into a new garden’s design instead of taking down old buildings. Finally， take the local climate， water quality and soil into account. Growing plants that are ill-suited to an area requires more water， energy and pesticides (杀虫剂)， all of which affect the environment.
语篇解读：本文是一篇说明文。文章主要介绍了一种新型的农业模式——城市农业。
(　　)8.What can we know about urban agriculture from Paragraph 1
A.It is thoroughly researched.
B.It is welcomed by city people.
C.It is environmentally friendly.
D.It is limited to industrial farms.
【解析】 细节理解题。根据第一段中的“Urban agriculture…is becoming increasingly popular and is viewed as a sustainable alternative to big industrial farms.”可知，城市农业受到城市居民的欢迎。
B
(　　)9.How does the author explain the reason for urban agriculture’s higher carbon intensity
A.By making a comparison. B.By telling a story.
C.By giving a definition. D.By using a quote.
【解析】 写作手法题。根据第二段中的“Using data from 73 low-tech city farms， community gardens and personal plots of land， Newell and his team compared the average carbon emissions of food produced at low-tech urban agriculture sites with those of conventionally grown crops.”可推知，作者通过作比较的方法来解释城市农业碳强度较高的原因。
A
(　　)10.According to Carola， what is a benefit of urban agriculture
A.It adds variety to urban people’s diet.
B.It provides recreational opportunities.
C.It strengthens the bonds of community.
D.It helps to contain drought and flooding.
【解析】 推理判断题。根据第二段中的“a good way to introduce fresh produce to urban ‘food deserts’ where healthy fruits and vegetables are hard to come by”可推知，城市农业的好处之一是它增加了城市居民饮食的多样性。
A
(　　)11.What is recommended to make urban agriculture more sustainable
A.Reconstructing gardens.
B.Developing greenhouse crops.
C.Selecting pesticide-free vegetables.
D.Growing plants suited to local conditions.
【解析】 细节理解题。根据最后一段中的“Finally， take the local climate， water quality and soil into account. Growing plants that are ill-suited to an area requires more water， energy and pesticides (杀虫剂)， all of which affect the environment.”可知，文章建议种植适合当地条件的植物，这样可以减小对环境的影响，从而促进城市农业可持续发展。

说明文 物种杂交 ★★★ 8 min P49
　　You’ve probably heard of a hybrid (杂交物种) in films or books. The centaurs in the Harry Potter films are hybrids of human and horse. 　12　
Hybridisation occurs in both plants and animals. 　13　 What’s more， many plants that people eat， from strawberries to carrots， corn and potatoes， have been created by hybridisation.
Cross-breeding (杂交) sometimes occurs when animals’ normal territory overlaps (部分重
叠). 　14　 The grolar bear is a hybrid that happens when grizzly and polar bears mate. As the environment warms， grizzlies in Alaska and Canada wander further north， bringing them into contact with polar bears.
Artificial mixing often happens in zoos， where different species that don’t normally meet in the wild can be introduced to each other. Ligers (lion and tiger hybrids) are unlikely to occur in nature， because the only place that their habitats overlap is the Gir Forest in India. 　15　 Mixed species are more likely to be born with health issues than other animals. Most hybrids born in zoos are infertile， which means they are unable to have babies. However， many cross-breeds born in the wild， like the grolar bear， can have their own babies.
　16　 “It’s part of the evolutionary process，” he says. Fertile hybrids can lead to the creation of a new species and increase the variety of living things.
语篇解读：本文是一篇说明文。文章主要介绍了动植物的杂交并且举例说明其发生条件以及结果。
A.Wildlife conservation is of significance.
B.Did you know hybridisation is a biological process
C.That’s due to habitat destruction or changing climate.
D.Did you know that hybrids appear in the natural world， too
E.Jimmy believes species hybridisation in nature is a good thing.
F.Many conservationists think that creating hybrids is a bad thing.
G.Living things， especially plants， will naturally hybridise in the wild.
