课时作业21 UNIT 5 WORKING THE LAND
Ⅰ.阅读理解
(2025·山东济南三模)Esther Kimani, a 29-year-old pioneer in agritech, is changing the lives of smallholder farmers across Africa. As the founder of Farmer Lifeline Technologies (FLT), she has applied artificial intelligence (AI) to fight against crop pests (害虫) and diseases, significantly reducing losses for rural farmers.
Kimani’s journey began in a small Kenyan village on the Aberdare Mountains. Witnessing firsthand the severe impact of pests and diseases on their crops—and consequently, their income—she understood early how agricultural losses could mean unmet basic needs like school fees and healthcare. Despite these challenges, Kimani became the first girl from her village to attend university, studying computer science. It was there that she recognized the potential of technology to solve rural farmers’ struggles, and that’s how FLT was born.
In Kenya alone，7.5 million smallholder farmers lose up to 50% of their yield (产量) to pests and diseases annually—losses that could feed millions. Traditional solutions like hiring agricultural consultants or using drones (无人机) are prohibitively expensive. To solve this critical issue, she developed an AI-powered camera, which is set up on farms at no upfront cost. It scans crops continuously and warns farmers through Short Message Service (SMS) for $3 per month when pests or diseases are detected.
A key focus for Kimani is supporting women farmers, who make up 43% of the agricultural labor force in developing nations, but who often lack access to technology. “Men in rural communities tend to have smartphones, while women rely on basic feature phones，” she notes. “Through SMS, we ensure women aren’t left behind.”
Kimani’s innovation has already impacted thousands of farmers, 78% of whom have reported a yield increase of over 36%. Her team aims to reach 200 thousand farms across the country within five years. For Kimani, success in 2030 means seeing 200 thousand smallholder farmers living with dignity—affording education, healthcare, and financial stability through improved yields. Kimani is not just building a company; she’s reshaping the future of African agriculture.

Ⅱ.阅读七选五
[语篇解读]　本文是一篇说明文。文章主要讲述了水果蔬菜上面贴的PLU(价格查询代码)标签的用途、由来，以及随着技术的发展，它可能会被标记水果和蔬菜代码的激光代替。
Whenever you pick up an apple and prepare to eat it, you may notice a small sticker attached to the fruit with a row of four or five numbers on it. That string of numbers is something called a Price Look-Up (PLU) code. 1 It’s designed to help supermarkets get to know their inventory (库存) of fruits and vegetables, and to make it easy for checkout clerks to know what to charge for a particular item. Thus, you can get through the line and out of the door more quickly.
A.The function is fairly simple.
B.PLU codes have a long history.
C.You probably think organic food is healthier.
D.The appearance of PLUs helped solve this problem.
E.Besides, it shows where the fruit or vegetable comes from.
F.The future of fruit and vegetable stickers is still uncertain.
G.You can use the PLU search app to know what a particular one means.
1.答案：A
解析：下文“It’s designed to help supermarkets get to know their inventory of fruits and vegetables, and to make it easy for checkout clerks to know what to charge for a particular item.”说明发明PLU代码的用途。空处引出下文，A项“功能相当简单”符合语境。故选A。
From the code, you can also know what specific variety of a particular fruit or vegetable you’re going to enjoy—whether it’s a Honeycrisp apple or a Shamouti orange. And it may tell you the size of the fruit or vegetable. 2 You may know whether it was grown conventionally (常规地) or on an organic farm.
A.The function is fairly simple.
B.PLU codes have a long history.
C.You probably think organic food is healthier.
D.The appearance of PLUs helped solve this problem.
E.Besides, it shows where the fruit or vegetable comes from.
F.The future of fruit and vegetable stickers is still uncertain.
G.You can use the PLU search app to know what a particular one means.
2.答案：E
解析：上文“And it may tell you the size of the fruit or vegetable.”说明从PLU标签中可以知道水果或蔬菜的尺寸。空处和上文为递进关系，同时说明能够从PLU代码中获取什么信息。E项中的it指代上文中的code，说明除了水果或蔬菜的大小，它还可以让人们知道蔬菜或水果来自哪里。E选项“此外，它还显示了水果或蔬菜的来源”符合语境。故选E。
A volunteer committee developed PLUs in 1988.One important reason why PLUs were invented was to enable supermarkets to tell the difference between conventionally grown fruits and vegetables and higher-priced organic food. As organic produce was being introduced then, cashiers often wrongly sold it at the conventional price. 3 There are now more than 1，500 different PLUs in use around the globe. 4 Just type in the code from a sticker on a piece of fruit, and it will tell you that 3114, for example, refers to an extra large green mango，belonging to the Keitt or Francis varieties of that fruit.
A.The function is fairly simple.
B.PLU codes have a long history.
C.You probably think organic food is healthier.
D.The appearance of PLUs helped solve this problem.
E.Besides, it shows where the fruit or vegetable comes from.
F.The future of fruit and vegetable stickers is still uncertain.
G.You can use the PLU search app to know what a particular one means.
3.答案：D
解析：上文“As organic produce was being introduced then, cashiers often wrongly sold it at the conventional price.”说明收银员经常错误地将有机农产品以传统产品的价格出售。空处给出解决此问题的办法。D项中的“this problem”指代上文中的“cashiers often wrongly sold it at the conventional price”，因此D项“PLU的出现帮助解决了这个问题”符合语境。故选D。
4.答案：G
解析：下文“Just type in the code from a sticker on a piece of fruit, and it will tell you that 3114, for example, refers to an extra large green mango，belonging to the Keitt or Francis varieties of that fruit.”说明输入水果贴纸上的代码会获得什么样的信息。空处承上启下。G项中的“what a particular one means”和上文中的“more than 1，500 different PLUs in use”相呼应，“the PLU search app”和下文中的“type in the code”相呼应，说明G项“你可以使用PLU搜索应用程序来了解某个特定代码的含义”符合语境。故选G。
5 The produce industry has been trying to develop biodegradable (可生物降解的) PLU stickers, but it’s difficult to do that. Eventually, PLU stickers may be replaced altogether by lasers that mark the codes on fruits and vegetables.
A.The function is fairly simple.

课时作业
Ⅰ.阅读理解
(2025·山东济南三模)Esther Kimani, a 29-year-old pioneer in agritech, is changing the lives of smallholder farmers across Africa. As the founder of Farmer Lifeline Technologies (FLT), she has applied artificial intelligence (AI) to fight against crop pests (害虫) and diseases, significantly reducing losses for rural farmers.
Kimani’s journey began in a small Kenyan village on the Aberdare Mountains. Witnessing firsthand the severe impact of pests and diseases on their crops—and consequently, their income—she understood early how agricultural losses could mean unmet basic needs like school fees and healthcare. Despite these challenges, Kimani became the first girl from her village to attend university, studying computer science. It was there that she recognized the potential of technology to solve rural farmers’ struggles, and that’s how FLT was born.
In Kenya alone，7.5 million smallholder farmers lose up to 50% of their yield (产量) to pests and diseases annually—losses that could feed millions. Traditional solutions like hiring agricultural consultants or using drones (无人机) are prohibitively expensive. To solve this critical issue, she developed an AI-powered camera, which is set up on farms at no upfront cost. It scans crops continuously and warns farmers through Short Message Service (SMS) for $3 per month when pests or diseases are detected.
A key focus for Kimani is supporting women farmers, who make up 43% of the agricultural labor force in developing nations, but who often lack access to technology. “Men in rural communities tend to have smartphones, while women rely on basic feature phones，” she notes. “Through SMS, we ensure women aren’t left behind.”
Kimani’s innovation has already impacted thousands of farmers, 78% of whom have reported a yield increase of over 36%. Her team aims to reach 200 thousand farms across the country within five years. For Kimani, success in 2030 means seeing 200 thousand smallholder farmers living with dignity—affording education, healthcare, and financial stability through improved yields. Kimani is not just building a company; she’s reshaping the future of African agriculture.

Ⅱ.阅读七选五
Whenever you pick up an apple and prepare to eat it, you may notice a small sticker attached to the fruit with a row of four or five numbers on it. That string of numbers is something called a Price Look-Up (PLU) code. 1 It’s designed to help supermarkets get to know their inventory (库存) of fruits and vegetables, and to make it easy for checkout clerks to know what to charge for a particular item. Thus, you can get through the line and out of the door more quickly.
From the code, you can also know what specific variety of a particular fruit or vegetable you’re going to enjoy—whether it’s a Honeycrisp apple or a Shamouti orange. And it may tell you the size of the fruit or vegetable. 2 You may know whether it was grown conventionally (常规地) or on an organic farm.
A volunteer committee developed PLUs in 1988.One important reason why PLUs were invented was to enable supermarkets to tell the difference between conventionally grown fruits and vegetables and higher-priced organic food. As organic produce was being introduced then, cashiers often wrongly sold it at the conventional price. 3 There are now more than 1，500 different PLUs in use around the globe. 4 Just type in the code from a sticker on a piece of fruit, and it will tell you that 3114, for example, refers to an extra large green mango，belonging to the Keitt or Francis varieties of that fruit.
5 The produce industry has been trying to develop biodegradable (可生物降解的) PLU stickers, but it’s difficult to do that. Eventually, PLU stickers may be replaced altogether by lasers that mark the codes on fruits and vegetables.
A.The function is fairly simple.
B.PLU codes have a long history.
C.You probably think organic food is healthier.
D.The appearance of PLUs helped solve this problem.
E.Besides, it shows where the fruit or vegetable comes from.
F.The future of fruit and vegetable stickers is still uncertain.
G.You can use the PLU search app to know what a particular one means.
[语篇解读]　本文是一篇说明文。文章主要讲述了水果蔬菜上面贴的PLU(价格查询代码)标签的用途、由来，以及随着技术的发展，它可能会被标记水果和蔬菜代码的激光代替。
1.答案：A
解析：下文“It’s designed to help supermarkets get to know their inventory of fruits and vegetables, and to make it easy for checkout clerks to know what to charge for a particular item.”说明发明PLU代码的用途。空处引出下文，A项“功能相当简单”符合语境。故选A。
2.答案：E
解析：上文“And it may tell you the size of the fruit or vegetable.”说明从PLU标签中可以知道水果或蔬菜的尺寸。空处和上文为递进关系，同时说明能够从PLU代码中获取什么信息。E项中的it指代上文中的code，说明除了水果或蔬菜的大小，它还可以让人们知道蔬菜或水果来自哪里。E选项“此外，它还显示了水果或蔬菜的来源”符合语境。故选E。
3.答案：D
解析：上文“As organic produce was being introduced then, cashiers often wrongly sold it at the conventional price.”说明收银员经常错误地将有机农产品以传统产品的价格出售。空处给出解决此问题的办法。D项中的“this problem”指代上文中的“cashiers often wrongly sold it at the conventional price”，因此D项“PLU的出现帮助解决了这个问题”符合语境。故选D。
4.答案：G
解析：下文“Just type in the code from a sticker on a piece of fruit, and it will tell you that 3114, for example, refers to an extra large green mango，belonging to the Keitt or Francis varieties of that fruit.”说明输入水果贴纸上的代码会获得什么样的信息。空处承上启下。G项中的“what a particular one means”和上文中的“more than 1，500 different PLUs in use”相呼应，“the PLU search app”和下文中的“type in the code”相呼应，说明G项“你可以使用PLU搜索应用程序来了解某个特定代码的含义”符合语境。故选G。
5.答案：F
解析：下文“The produce industry has been trying to develop biodegradable PLU stickers, but it’s difficult to do that. Eventually, PLU stickers may be replaced altogether by lasers that mark the codes on fruits and vegetables.”说明PLU标签在未来可能会被标记水果和蔬菜代码的激光完全取代。F项“水果和蔬菜标签的未来仍不确定”适合作为本段的主旨句，统领本段。故选F。
