A
(2025·河北滄州高一上期末)
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(傳粉) 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(多樣性) 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(假設)，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.
語篇解讀　本文是一篇說明文。文章主要介紹了一項新研究發現美國西部每天可能有數千萬只蜜蜂被車輛撞死，并提出在路邊而非路中間創建棲息地可減少蜜蜂死亡。
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.
答案　A
解析　段落大意題。根據第二段中“Most studies have focused on forests and larger insects.But bee diversity(多樣性) is greatest in dry，open areas，and most bees are tiny—just 2 to 25 millimeters long.”可知，本段主要討論了過去這類研究的局限性，因為聚焦森林和較大的昆蟲它們沒有關注到蜜蜂。故選A。
2．How does the author mainly develop paragraph 3 and paragraph 4
A．By making a comparison.
B．By listing related numbers.
C．By showing real data related to bees.
D．By stating the result of the team’s study.
答案　B
解析　推理判斷題。根據第三、四段中多處提到的數據可知，這兩段主要通過列舉相關數字來展開論述。故選B。
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
解析　細節理解題。根據最后一段中“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.”可知，防止蜜蜂被殺死的一種方法是在路邊種植植物。故選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.
答案　C
解析　寫作意圖題。通讀全文，尤其是第一段中“Tens of millions of bees are likely being killed each day by vehicles in the western United States，a new study finds.”可知，文章通過研究結果和具體數據說明了每天可能有大量蜜蜂因車輛撞擊而死亡，并提出了減少蜜蜂死亡的建議。因此，文章的主要目的是介紹蜜蜂面臨的危險，即車輛對蜜蜂的威脅。故選C。
B(此篇精讀)
(2025·河南周口高一上期末)
Fish farming is a form of aquaculture(水產養殖)，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(藻類) 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(再循環) 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(海參) 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.”
語篇解讀　本文是一篇說明文。文章介紹了科學家使用海參解決水產養殖中的廢物帶來的困擾。
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　推理判斷題。根據第一段最后一句“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，目前水產養殖面臨的問題是廢物處理問題。故選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　細節理解題。根據第三段的“They feed on very tiny animals，algae，and the waste on the seabed.”可知，海參以微小動物、藻類和海底的廢物為食，所以一些水產養殖場引進海參來應對廢物問題。故選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　詞義猜測題。根據下文的“So in such environments，the ocean animals are just doing what they do naturally out in the wild.”可知，在這樣的環境中，海洋動物們所做的事情和它們在野外環境中所做的事情相同。由此推知，海洋動物專家們想要做的是“模擬”自然環境。故mimic意為“模擬”，與copy意思相近。故選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　標題歸納題。根據第三段的“Now，some fish farms are turning to sea cucumbers(海參) for help.The bottom-animals are often called the ocean’s ‘cleaners’．”及全文可知，本文主要介紹水產養殖場所面臨的廢物處理問題，以及目前一些水產養殖場采取的措施——引進海參。D項“海參幫助應對水產養殖場的廢物處理問題”能夠概括文章內容，適合作文章標題。故選D。
[詞匯積累]
1．take up開始從事(某項活動)；接受(挑戰、任務等)；占據(本文為此義)
2．sickness(派)＝sick＋ness n．疾病
3．turn to...for help求助于……
4．feed on以……為食物
5．ecosystem n．生態系統

1．Fish farming is a form of aquaculture，in which fish are raised in pools to be sold as food.
分析：此句為復合句。in which引導定語從句，先行詞為aquaculture，in which在從句中充當狀語。
翻譯：養魚業是水產養殖的一種形式，在池塘里飼養魚類，作為食物出售。
2．Even better，the sand they take in will come out again in the form of CaCO3，which helps support the growth of coral reefs.
分析：此句為復合句。sand后為省略了that的定語從句，sand為先行詞，that在從句中充當賓語，可省略。which引導非限制性定語從句，CaCO3為先行詞，which在從句中充當主語。
翻譯：更好的是，它們攝入的沙子會以碳酸鈣的形式再次排出，這有助于促進珊瑚礁的生長。

(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.
語篇解讀　這是一篇說明文。文章主要介紹了動物的交流方式。
1．答案　G
解析　根據上文“...The communication signals are various and have developed over countless generations，finely adjusted to meet their specific needs.”可知，動物有獨特的交流方式，交流信號多種多樣，經過無數代的演化發展，經過精細調整以滿足其特定的需求。G選項“By understanding these signals，we can appreciate the animal world more easily.”承接上文，說明理解這些信號的意義，符合語境。故選G。
2．答案　D
解析　根據上文“Males sing to mark their territory，warning other males to stay away.”可知，雄性夜鶯唱歌是為了標記自己的領地，警告其他雄性夜鶯遠離。根據下文“The more powerful the song is，the more likely the female is to mate.”可知，歌聲越有力，雌性夜鶯就越有可能與之交配。D選項“And another purpose is to catch the attention of a female.”說明雄性夜鶯唱歌的另一個目的是引起雌性夜鶯的注意，符合語境。故選D。
3．答案　E
解析　下文“Wolves use a complex system of body postures...”舉例說明狼使用復雜的身體姿勢系統來交流，如尾巴高高豎起且僵硬表示在群體中的權力，尾巴放松、輕輕擺動表示友好情緒等。E選項“Body language is also an important way to communicate.”引出下文關于狼通過肢體語言交流的內容。故選E。
4．答案　B
解析　根據上文“Ants release pheromones along its way to lead fellow ants to food sources.”可知，螞蟻會沿途釋放信息素，引導同伴找到食物來源。B選項“It’s like a map guiding them to find the destination.”把信息素比作地圖，形象地說明了信息素對螞蟻找到食物來源的引導作用，符合語境。故選B。
5．答案　F
解析　根據下文“The more brilliant the display is，the more likely they are to catch a female’s eye and pass on their genes.”可知，孔雀在繁殖季節展開美麗的尾巴，展示得越耀眼，就越有可能吸引雌孔雀的注意，并傳遞它們的基因。F選項“The bright colors and patterns show good health and genetic quality.”解釋了孔雀尾巴展示的意義，即其鮮艷的顏色和圖案所代表的含義，起到承上啟下的作用。故選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(傳粉) wild plants and a third of the world’s crops.
語篇解讀　本文是一篇說明文。文章主要介紹了一項新研究發現美國西部每天可能有數千萬只蜜蜂被車輛撞死，并提出在路邊而非路中間創建棲息地可減少蜜蜂死亡。
Ⅲ.主題語篇閱讀
Scientists have studied the “insect disaster” by counting dead insects along roadsides.Most studies have focused on forests and larger insects.But bee diversity(多樣性) 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(假設)，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.
√
段落大意題。根據第二段中“Most studies have focused on forests and larger insects.But bee diversity(多樣性) is greatest in dry，open areas，and most bees are tiny—just 2 to 25 millimeters long.”可知，本段主要討論了過去這類研究的局限性，因為聚焦森林和較大的昆蟲它們沒有關注到蜜蜂。故選A。
解析
2.How does the author mainly develop paragraph 3 and paragraph 4
A.By making a comparison.
B.By listing related numbers.
C.By showing real data related to bees.
D.By stating the result of the team’s study.
√
推理判斷題。根據第三、四段中多處提到的數據可知，這兩段主要通過列舉相關數字來展開論述。故選B。
解析
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.
√
細節理解題。根據最后一段中“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.”可知，防止蜜蜂被殺死的一種方法是在路邊種植植物。故選C。
解析
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.
√
寫作意圖題。通讀全文，尤其是第一段中“Tens of millions of bees are likely being killed each day by vehicles in the western United States，a new study finds.”可知，文章通過研究結果和具體數據說明了每天可能有大量蜜蜂因車輛撞擊而死亡，并提出了減少蜜蜂死亡的建議。因此，文章的主要目的是介紹蜜蜂面臨的危險，即車輛對蜜蜂的威脅。故選C。
解析

(2025·河南周口高一上期末)
Fish farming is a form of aquaculture(水產養殖)，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.
語篇解讀　本文是一篇說明文。文章介紹了科學家使用海參解決水產養殖中的廢物帶來的困擾。
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(藻類) 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(再循環) 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(海參) 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.
√
推理判斷題。根據第一段最后一句“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，目前水產養殖面臨的問題是廢物處理問題。故選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.
√
細節理解題。根據第三段的“They feed on very tiny animals，algae，and the waste on the seabed.”可知，海參以微小動物、藻類和海底的廢物為食，所以一些水產養殖場引進海參來應對廢物問題。故選D。
解析
7.What does the underlined word “mimic” in the last paragraph mean
A.Copy. B.Explore.
C.Protect. D.Clean.
√
詞義猜測題。根據下文的“So in such environments，the ocean animals are just doing what they do naturally out in the wild.”可知，在這樣的環境中，海洋動物們所做的事情和它們在野外環境中所做的事情相同。由此推知，海洋動物專家們想要做的是“模擬”自然環境。故mimic意為“模擬”，與copy意思相近。故選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
√
標題歸納題。根據第三段的“Now，some fish farms are turning to sea cucumbers(海參) for help.The bottom-animals are often called the ocean’s ‘cleaners’.”及全文可知，本文主要介紹水產養殖場所面臨的廢物處理問題，以及目前一些水產養殖場采取的措施——引進海參。D項“海參幫助應對水產養殖場的廢物處理問題”能夠概括文章內容，適合作文章標題。故選D。
解析
1.take up開始從事(某項活動)；接受(挑戰、任務等)；占據(本文為此義)
2.sickness(派)＝sick＋ness n.疾病
3.turn to...for help求助于……
4.feed on以……為食物
5.ecosystem n.生態系統

more easily.
√
The communication signals are various and have developed over countless generations，finely adjusted to meet their specific needs. 1
根據上文“...The communication signals are various and have developed over countless generations，finely adjusted to meet their specific needs.”可知，動物有獨特的交流方式，交流信號多種多樣，經過無數代的演化發展，經過精細調整以滿足其特定的需求。G選項“By understanding these signals，we can appreciate the animal world more easily.”承接上文，說明理解這些信號的意義，符合語境。故選G。
解析
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.

√
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.
根據上文“Males sing to mark their territory，warning other males to stay away.”可知，雄性夜鶯唱歌是為了標記自己的領地，警告其他雄性夜鶯遠離。根據下文“The more powerful the song is，the more likely the female is to mate.”可知，歌聲越有力，雌性夜鶯就越有可能與之交配。D選項“And another purpose is to catch the attention of a female.”說明雄性夜鶯唱歌的另一個目的是引起雌性夜鶯的注意，符合語境。故選D。
解析
A.People recognize the signals suggesting changes.
B.It’s like a map guiding them to find the destination.

√
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.
下文“Wolves use a complex system of body postures...”舉例說明狼使用復雜的身體姿勢系統來交流，如尾巴高高豎起且僵硬表示在群體中的權力，尾巴放松、輕輕擺動表示友好情緒等。E選項“Body language is also an important way to communicate.”引出下文關于狼通過肢體語言交流的內容。故選E。
解析
A.People recognize the signals suggesting changes.

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.
根據下文“The more brilliant the display is，the more likely they are to catch a female’s eye and pass on their genes.”可知，孔雀在繁殖季節展開美麗的尾巴，展示得越耀眼，就越有可能吸引雌孔雀的注意，并傳遞它們的基因。F選項“The bright colors and patterns show good health and genetic quality.”解釋了孔雀尾巴展示的意義，即其鮮艷的顏色和圖案所代表的含義，起到承上啟下的作用。故選F。
解析
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.
