(2025·河北沧州高一上期末)
Tens of millions of bees are likely being killed each day by vehicles in the western United States，a new study finds.The paper，published in Sustainable Environment，is the first to show how cars may be causing the loss of bees.Bees are important because they help pollinate(传粉) wild plants and a third of the world’s crops.
Scientists have studied the “insect disaster” by counting dead insects along roadsides.Most studies have focused on forests and larger insects.But bee diversity(多样性) is greatest in dry，open areas，and most bees are tiny—just 2 to 25 millimeters long.
A research team from Utah State University studied bee deaths by driving on highways，paved roads，and unpaved roads during the day when bees are active.They made 29 trips around Utah in spring and summer，traveling more than 9,334 kilometers，and identified bees that were hit by cars.Every trip resulted in at least one bee dying，and they found 14 different species.
The researchers guessed that one car driving between Salt Lake City and Moab might kill 50 to 175 bees.Based on traffic data，that means several million bees are killed when 94,000 cars travel that route each day.Millions of cars run in Utah daily，and similar trips happen in nearby states，so the total number of bees killed each day in the region is likely in the tens of millions.
Although the numbers are based on simple assumptions(假设)，they are still important.There are ways to reduce these deaths.Research has shown that bees usually avoid crossing roads unless there are plants in the middle.So，creating healthy habitat along both sides of a road，but not in the middle，could help.
语篇解读　本文是一篇说明文。文章主要介绍了一项新研究发现美国西部每天可能有数千万只蜜蜂被车辆撞死，并提出在路边而非路中间创建栖息地可减少蜜蜂死亡。

3．Which is one way to prevent bees from being killed
A．Raising drivers’ awareness.
B．Placing flowers in the middle.
C．Growing plants on roadsides.
D．Leaving more space available.
答案　C

4．What is the author’s purpose in writing the text
A．To explain the bee’s diversity.
B．To remind readers to drive less.
C．To introduce the danger to bees.
D．To ask people to grow more flowers.

B(此篇精读)
(2025·河南周口高一上期末)
Fish farming is a form of aquaculture(水产养殖)，in which fish are raised in pools to be sold as food.They take up over half of the world’s fish supply and are key for meeting the needs of an ever-growing human population.However，fish farms now face a big challenge.
The uneaten food and waste made by the thousands of sea animals limited to small spaces often build up to harmful levels.Every year，a large number of fish die because of sicknesses.Besides，the phosphorous and nitrogen that come out from the waste can cause algae(藻类) to grow a lot.These algae take up the O2 in the water.This makes it hard for the fish to breathe and they can die.Right now，fish farms fix these problems by using recirculating(再循环) systems.These systems clean the water and deal with the waste.But it costs a lot to put them in and they are hard to keep in good working order.
Now，some fish farms are turning to sea cucumbers(海参) for help.The bottom-animals are often called the ocean’s “cleaners”．They feed on very tiny animals，algae，and the waste on the seabed.Even better，the sand they take in will come out again in the form of CaCO3，which helps support the growth of coral reefs(珊瑚礁)．Sea cucumbers are considered a delicious food in some parts of the world.Once their numbers grow，they could also bring an extra income source for fish farms.
Adding sea cucumbers to fish farms is part of a bigger plan to make them into balanced and good-for-long-time ecosystems.Experts believe it can be achieved if we grow many different kinds of ocean animals from different parts of the food chain.
“We’re trying to mimic natural environments，” says ocean researcher Chris Pearce.“So in such environments，the ocean animals are just doing what they do naturally out in the wild.But when we put them together with other kinds of animals，they are helping the ecosystem.”
语篇解读　本文是一篇说明文。文章介绍了科学家使用海参解决水产养殖中的废物带来的困扰。
5．What is the main problem that fish farms face
A．Unexplained death of fish.
B．High cost of fish food.
C．Waste management.
D．Strong competition.
答案　C
解析　推理判断题。根据第一段最后一句“However，fish farms now face a big challenge.”以及第二段的“The uneaten food and waste made by the thousands of sea animals limited to small spaces often build up to harmful levels.”可推知，目前水产养殖面临的问题是废物处理问题。故选C。
6．Why are sea cucumbers introduced by some fish farms
A．They take in CaCO3.
B．They do good to the algae.
C．They serve as food for fish.
D．They deal with waste on the seabed.
答案　D
解析　细节理解题。根据第三段的“They feed on very tiny animals，algae，and the waste on the seabed.”可知，海参以微小动物、藻类和海底的废物为食，所以一些水产养殖场引进海参来应对废物问题。故选D。
7．What does the underlined word “mimic” in the last paragraph mean
A．Copy. B．Explore.
C．Protect. D．Clean.
答案　A
解析　词义猜测题。根据下文的“So in such environments，the ocean animals are just doing what they do naturally out in the wild.”可知，在这样的环境中，海洋动物们所做的事情和它们在野外环境中所做的事情相同。由此推知，海洋动物专家们想要做的是“模拟”自然环境。故mimic意为“模拟”，与copy意思相近。故选A。
8．What is the best title for the text
A．Balanced Ecosystems Are out of Reach
B．Recirculating Systems Bring New Hope for Fish Farms
C．The World’s Fish Supply Is Facing Greater Challenges
D．Sea Cucumbers Help with Fish Farms’ Waste Treatment
答案　D
解析　标题归纳题。根据第三段的“Now，some fish farms are turning to sea cucumbers(海参) for help.The bottom-animals are often called the ocean’s ‘cleaners’．”及全文可知，本文主要介绍水产养殖场所面临的废物处理问题，以及目前一些水产养殖场采取的措施——引进海参。D项“海参帮助应对水产养殖场的废物处理问题”能够概括文章内容，适合作文章标题。故选D。

(2025·北京房山高一上期末)
Animals have their own unique ways of communicating，which play an important role in their survival and social interactions.The communication signals are various and have developed over countless generations，finely adjusted to meet their specific needs. 1
One common form of animal communication is through vocalizations.Birds are masters of this.For example，the melodious songs of nightingales aren’t just for our enjoyment.Males sing to mark their territory，warning other males to stay away. 2 The more powerful the song is，the more likely the female is to mate.
3 Wolves use a complex system of body postures.When a wolf holds its tail high and stiff，it shows its power in its group.In contrast，a relaxed，loosely wagging tail indicates a friendly mood.Submissive wolves，on the other hand，will lower their bodies，tuck their tails，and avoid direct eye contact，communicating their non-threatening status.
Chemical signals，often in the form of pheromones(信息素)，are widely used too.Ants release pheromones along its way to lead fellow ants to food sources. 4 Female moths can detect the pheromones of male moths from miles away，enabling them to find each other for mating.
Some animals even use visual displays.Peacocks(孔雀) spread their beautiful tails in a dazzling fan.This isn’t just for show; it’s a way to attract peahens during the breeding season. 5 The more brilliant the display is，the more likely they are to catch a female’s eye and pass on their genes.
In conclusion，the animal kingdom’s communication systems are a wonder of nature.Understanding these communication methods gives us a fascinating peek into the animal kingdom’s hidden social lives.
A．People recognize the signals suggesting changes.
B．It’s like a map guiding them to find the destination.
C．A wagging tail can mean friendliness or excitement.
D．And another purpose is to catch the attention of a female.
E．Body language is also an important way to communicate.
F．The bright colors and patterns show good health and genetic quality.
G．By understanding these signals，we can appreciate the animal world more easily.
语篇解读　这是一篇说明文。文章主要介绍了动物的交流方式。
1．答案　G
解析　根据上文“...The communication signals are various and have developed over countless generations，finely adjusted to meet their specific needs.”可知，动物有独特的交流方式，交流信号多种多样，经过无数代的演化发展，经过精细调整以满足其特定的需求。G选项“By understanding these signals，we can appreciate the animal world more easily.”承接上文，说明理解这些信号的意义，符合语境。故选G。
2．答案　D
解析　根据上文“Males sing to mark their territory，warning other males to stay away.”可知，雄性夜莺唱歌是为了标记自己的领地，警告其他雄性夜莺远离。根据下文“The more powerful the song is，the more likely the female is to mate.”可知，歌声越有力，雌性夜莺就越有可能与之交配。D选项“And another purpose is to catch the attention of a female.”说明雄性夜莺唱歌的另一个目的是引起雌性夜莺的注意，符合语境。故选D。
3．答案　E
解析　下文“Wolves use a complex system of body postures...”举例说明狼使用复杂的身体姿势系统来交流，如尾巴高高竖起且僵硬表示在群体中的权力，尾巴放松、轻轻摆动表示友好情绪等。E选项“Body language is also an important way to communicate.”引出下文关于狼通过肢体语言交流的内容。故选E。
4．答案　B
解析　根据上文“Ants release pheromones along its way to lead fellow ants to food sources.”可知，蚂蚁会沿途释放信息素，引导同伴找到食物来源。B选项“It’s like a map guiding them to find the destination.”把信息素比作地图，形象地说明了信息素对蚂蚁找到食物来源的引导作用，符合语境。故选B。
5．答案　F
解析　根据下文“The more brilliant the display is，the more likely they are to catch a female’s eye and pass on their genes.”可知，孔雀在繁殖季节展开美丽的尾巴，展示得越耀眼，就越有可能吸引雌孔雀的注意，并传递它们的基因。F选项“The bright colors and patterns show good health and genetic quality.”解释了孔雀尾巴展示的意义，即其鲜艳的颜色和图案所代表的含义，起到承上启下的作用。故选F。

Tens of millions of bees are likely being killed each day by vehicles in the western United States，a new study finds.The paper，published in Sustainable Environment，is the first to show how cars may be causing the loss of bees.Bees are important because they help pollinate(传粉) wild plants and a third of the world’s crops.
语篇解读　本文是一篇说明文。文章主要介绍了一项新研究发现美国西部每天可能有数千万只蜜蜂被车辆撞死，并提出在路边而非路中间创建栖息地可减少蜜蜂死亡。
Ⅲ.主题语篇阅读
Scientists have studied the “insect disaster” by counting dead insects along roadsides.Most studies have focused on forests and larger insects.But bee diversity(多样性) is greatest in dry，open areas，and most bees are tiny—just 2 to 25 millimeters long.
A research team from Utah State University studied bee deaths by driving on highways，paved roads，and unpaved roads during the day when bees are active.They made 29 trips around Utah in spring and summer，traveling more than 9,334 kilometers，and identified bees that were hit by cars.Every trip resulted in at least one bee dying，and they found 14 different species.
The researchers guessed that one car driving between Salt Lake City and Moab might kill 50 to 175 bees.Based on traffic data，that means several million bees are killed when 94,000 cars travel that route each day.Millions of cars run in Utah daily，and similar trips happen in nearby states，so the total number of bees killed each day in the region is likely in the tens of millions.
Although the numbers are based on simple assumptions(假设)，they are still important.There are ways to reduce these deaths.Research has shown that bees usually avoid crossing roads unless there are plants in the middle.So，creating healthy habitat along both sides of a road，but not in the middle，could help.
1.What is paragraph 2 mainly about
A.Limitations on such studies.
B.The influence of climate on bees.
C.Living areas of various bees.
D.Scientists’ efforts to study diversity.
√

(2025·河南周口高一上期末)
Fish farming is a form of aquaculture(水产养殖)，in which fish are raised in pools to be sold as food.They take up over half of the world’s fish supply and are key for meeting the needs of an ever-growing human population.However，fish farms now face a big challenge.
语篇解读　本文是一篇说明文。文章介绍了科学家使用海参解决水产养殖中的废物带来的困扰。
The uneaten food and waste made by the thousands of sea animals limited to small spaces often build up to harmful levels.Every year，a large number of fish die because of sicknesses.Besides，the phosphorous and nitrogen that come out from the waste can cause algae(藻类) to grow a lot.These algae take up the O2 in the water.This makes it hard for the fish to breathe and they can die.Right now，fish farms fix these problems by using recirculating(再循环) systems.These systems clean the water and deal with the waste.But it costs a lot to put them in and they are hard to keep in good working order.
Now，some fish farms are turning to sea cucumbers(海参) for help.The bottom-animals are often called the ocean’s “cleaners”.They feed on very tiny animals，algae，and the waste on the seabed.Even better，the sand they take in will come out again in the form of CaCO3，which helps support the growth of coral reefs(珊瑚礁).Sea cucumbers are considered a delicious food in some parts of the world.Once their numbers grow，they could also bring an extra income source for fish farms.
Adding sea cucumbers to fish farms is part of a bigger plan to make them into balanced and good-for-long-time ecosystems.Experts believe it can be achieved if we grow many different kinds of ocean animals from different parts of the food chain.
“We’re trying to mimic natural environments，” says ocean researcher Chris Pearce.“So in such environments，the ocean animals are just doing what they do naturally out in the wild.But when we put them together with other kinds of animals，they are helping the ecosystem.”
5.What is the main problem that fish farms face
A.Unexplained death of fish.
B.High cost of fish food.
C.Waste management.
D.Strong competition.
√
推理判断题。根据第一段最后一句“However，fish farms now face a big challenge.”以及第二段的“The uneaten food and waste made by the thousands of sea animals limited to small spaces often build up to harmful levels.”可推知，目前水产养殖面临的问题是废物处理问题。故选C。
解析
6.Why are sea cucumbers introduced by some fish farms
A.They take in CaCO3.
B.They do good to the algae.
C.They serve as food for fish.
D.They deal with waste on the seabed.
√
细节理解题。根据第三段的“They feed on very tiny animals，algae，and the waste on the seabed.”可知，海参以微小动物、藻类和海底的废物为食，所以一些水产养殖场引进海参来应对废物问题。故选D。
解析
7.What does the underlined word “mimic” in the last paragraph mean
A.Copy. B.Explore.
C.Protect. D.Clean.
√
词义猜测题。根据下文的“So in such environments，the ocean animals are just doing what they do naturally out in the wild.”可知，在这样的环境中，海洋动物们所做的事情和它们在野外环境中所做的事情相同。由此推知，海洋动物专家们想要做的是“模拟”自然环境。故mimic意为“模拟”，与copy意思相近。故选A。
解析
8.What is the best title for the text
A.Balanced Ecosystems Are out of Reach
B.Recirculating Systems Bring New Hope for Fish Farms
C.The World’s Fish Supply Is Facing Greater Challenges
D.Sea Cucumbers Help with Fish Farms’ Waste Treatment
√
标题归纳题。根据第三段的“Now，some fish farms are turning to sea cucumbers(海参) for help.The bottom-animals are often called the ocean’s ‘cleaners’.”及全文可知，本文主要介绍水产养殖场所面临的废物处理问题，以及目前一些水产养殖场采取的措施——引进海参。D项“海参帮助应对水产养殖场的废物处理问题”能够概括文章内容，适合作文章标题。故选D。
解析
1.take up开始从事(某项活动)；接受(挑战、任务等)；占据(本文为此义)
2.sickness(派)＝sick＋ness n.疾病
3.turn to...for help求助于……
4.feed on以……为食物
