阅读下列短文，从每题所给A、B、C和D四个选项中，选出最佳答案。
A
We may think that gift giving is a purely human trait, but it turns out many other animals also give presents to their mates and friends.
Gift giving during mating has been observed in species as different as snails, earthworms and squid. Birds also enjoy this practice—male great grey shrikes, for example, stick small dead animals on thorns and twigs to attract females.
However, the behavior is most common among insects and spiders. Nursery web spiders, for instance, offer possible mates prey wrapped in silk, adding special chemicals to make it more appealing.
Some insects even make the final sacrifice for the females they wish to win over. The male redback spider does a backflip into the female’s mouth while mating, letting her bite the end of his body until he is finally eaten.
All these are examples of mating gifts, given by males to females to persuade them to mate. Still, animals have also been known to give gifts just to make the receiver happy. For example, dolphins have been seen offering food to humans. There are also stories of crows bringing gifts to people who once helped them.
Selfless gift giving is also common in bonobos, a type of ape that shares nearly 99% of its DNA with humans.
So, this leads to a question—why do animals give each other gifts Since the behavior has developed independently in many species, it probably helps both males and females reproduce more successfully.
But if that doesn’t sound very romantic, be encouraged by this: animals like crows and bonobos also seem to find joy in the simple act of giving.

Around the world, expanding farmland is increasingly overlapping with elephant habitats, often leading to dangerous situations as elephants eat and damage people's crops. But in Kenya, after decades of research, experts have developed a simple yet clever solution to keep elephants away: fences made with beehives.
So why do elephants dislike bees so much And can bees really help maintain peace in our increasingly crowded world
It all began in the early 2000s, when Fritz Vollrath, an ecologist at the University of Oxford and chairman of the charity Save the Elephants, and Iain Douglas-Hamilton, founder of Save the Elephants, heard a local story from Kenyan farmers. They said that trees in some areas were not harmed by elephants because those trees contained beehives.
By 2007, their research confirmed that elephants not only avoid trees with beehives of wild African honeybees, but also communicate with each other to warn others to stay away. Lucy King, coexistence director at the organization, explains, "We know that they can get stung, and we know that they never forget."
Besides protecting crops from elephants and ensuring food supply, the beehive fences bring other benefits to the local communities.
For example, they provide farmers with extra income through honey production. Mwamba, who lives in one of the villages where the beehive fences were tested and now works as a project officer for Save the Elephants, says, "If a farmer has honey and has crops, that's actually enough to support the family."
Before the beehive fences were introduced, "elephants had invaded and damaged most of the farms here," Mwamba recalls. "Now, people can live without constant fear."
1. What is the main problem mentioned in the first paragraph
A. Elephants are losing their habitats to farmland.
B. Farmers are killing too many elephants.
C. Expanding farmland is creating conflicts with elephants.
D. Bee populations are declining in Kenya.
2. How did researchers get the idea of using beehive fences
A. From watching elephant behavior in zoos.
B. From a story told by local farmers.
C. From studying bee behavior in laboratories.
D. From reading ancient scientific reports.
3. According to Lucy King, what do we know about elephants
A. They are not afraid of bee stings.
B. They quickly forget painful experiences.
C. They warn each other about bees.
D. They cannot be stung by bees.
4. Besides protecting crops, what other benefit do beehive fences provide
A. They attract tourists to the area.
B. They provide additional income from honey.
C. They help bees produce more honey.
D. They make elephants produce more honey.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
The stray dog appeared on the coldest night of the year. Li Yan, a high school senior busy with college applications, almost tripped over him while taking out the trash. The animal was curled against the dumpster, his dirty fur covered with snow. One of his back legs shook—an old injury, she guessed—and his ribs showed clearly under his skin. Something about his quiet cry, more sad than fearful, made her stop.
Over the next week, Li Yan brought leftovers to the alley: steamed buns from dinner, sausages from breakfast. She named him Ping An ("safety"), saying it softly as he ate, as if the word could protect him from the world. Her parents, busy with their divorce papers, hardly noticed her being gone.
Then came the storm. Freezing rain covered the streets, and Li Yan woke to the sound of desperate scratching at her door. Ping An stood there, his paw bleeding onto the welcome mat. A piece of glass shone between his toes. Worried, she wrapped him in her quilt and ran downstairs—only to stop outside the locked neighborhood clinic.
"You're lucky I was working late," a voice called. Dr. Chen, the older vet who'd cared for Li Yan's childhood rabbit, stood under an umbrella, keys in hand. His clinic smelled of medicine and old books. As he carefully removed the glass, Li Yan shared her worry: "My mom's allergic... I can't keep him." Dr. Chen bandaged Ping An's paw quietly, then slid a small book across the table: Foster Programs for Strays. "Your secret is safe here," he said, eyes softly smiling. "But this friend needs more than bandages. He needs a plan."
That night, Li Yan made a bed for Ping An in a cardboard box near her heater. As his breathing became steady, she looked at Dr. Chen's notes—"Too thin. Needs to learn to trust."—and understood the words described her, too.

答案与解析：
1. 答案B解析：主旨大意题。文章开篇即点明主旨：送礼并非人类独有，许多动物也有此行为。全文随后分别介绍了动物为求偶而送礼和利他性送礼等多种情况，都支撑了这一核心观点。A项与文章主旨相反；C项中的“only”过于绝对，与原文“most common”不符；D项忽略了文中关于利他性送礼的内容。
2. 答案B解析：细节理解题。根据第五段第一句“All these are examples of mating gifts, given by males to females to persuade them to mate.”可知，雄性动物赠送“婚礼物”的直接目的是为了说服雌性与之交配。A项可能是礼物隐含的效果，但非文中直接阐明的目的；C项和D项均与文中描述不符。
3. 答案C解析：细节理解题。问题关键词是“selfless”（无私的）。根据第五段和第六段，文章将乌鸦回报帮助过它的人的行为与求偶送礼区分开，归类为“just to make the receiver happy”和“Selfless gift giving”。因此，乌鸦的行为是利他性送礼的例子。A、B、D三项均属于文中明确说明的以“求偶”为目的的礼物。
4. 答案C解析：推理判断题。通读全文可知，动物送礼既有为了“求偶繁殖”的目的（如各种昆虫、蜘蛛和伯劳鸟），也有看似“利他”或为了取悦对方的目的（如海豚、乌鸦和倭黑猩猩）。因此可以推断，这种行为在不同情境下可能服务于不同的目的。A项与第七段“the behavior has developed independently in many species”相悖；B项中的“solely”（ solely）过于绝对；D项中的“only”也过于绝对，送礼行为并非高智力动物的专利，昆虫和蜘蛛也有。

答案与解析：
1.答案C解析：细节理解题。根据第一段首句"Around the world, expanding farmland is increasingly overlapping with elephant habitats, often leading to dangerous situations as elephants eat and damage people's crops."可知，主要问题是不断扩张的农田与大象栖息地重叠，导致大象破坏庄稼，引发人象冲突。
2.答案B解析：细节理解题。根据第三段"heard a local story from Kenyan farmers. They said that trees in some areas were not harmed by elephants because those trees contained beehives."可知，研究人员是从当地农民讲述的故事中获得灵感的。
3.答案C解析：细节理解题。根据第四段"elephants not only avoid trees with beehives of wild African honeybees, but also communicate with each other to warn others to stay away."可知，大象会互相沟通警告彼此远离蜂巢。
4.答案B解析：细节理解题。根据第五、六段"bring other benefits to the local communities"和"provide farmers with extra income through honey production"可知，蜂巢围栏除了保护庄稼外，还能通过生产蜂蜜为农民提供额外收入。

During extreme flood events, your government may issue warnings. Check your local weather reports and follow your 9. ______ (government) updates, especially as storms become 10. ______ (severe) and harder to predict.
答案与解析：
1. to develop解析：考查非谓语动词。固定结构 "take + time + to do sth." 表示“花费时间做某事”。这里指洪水形成需要花费数小时甚至数天。
2. suddenly解析：考查词性转换。空格处需要副词来修饰后面的动词短语 "turning..."，表示“突然将……变成”。形容词 "sudden" 的副词形式是 "suddenly"。
3. to解析：考查固定搭配。 "from... to..." 表示“从……到……”，用于连接时间的起点和终点。
4. likely解析：考查形容词比较级。空格前有 "more"，提示此处应用形容词原形 "likely" 来构成比较级 "more likely"（更可能）。
5. to experience解析：考查固定句式。 "be likely to do sth." 是一个常用句式，表示“很可能做某事”。
6. which解析：考查定语从句。空格前有逗号，这是一个非限制性定语从句，修饰前面整个主句“道路和人行道又硬又不吸水”，关系代词 "which" 指代整个主句内容，在从句中作主语。
7. to解析：考查固定短语。 "lead to" 是固定搭配，意为“导致，引起”。
8. that解析：考查宾语从句。动词 "require" 后接了一个宾语从句 "residents of flood-prone areas buy flood insurance"，且从句成分完整，故应用引导词 "that"。在表示“要求、建议、命令”等动词后的宾语从句中，谓语动词常用 "should + 动词原形" 或直接用动词原形，此处 "buy" 即为动词原形。
9. government's解析：考查名词所有格。空格后是名词 "updates"，这里表示“政府的更新”，需要用名词所有格形式来表示所属关系。
10. more severe解析：考查形容词比较级。空格后由 "and" 连接两个并列的比较级结构 "more severe and harder to predict"。根据语境“风暴变得更加猛烈和难以预测”，此处应用 "severe" 的比较级 "more severe"。

参考范文：
Paragraph 1:
Li Yan knew she had to talk to her parents, no matter how difficult it might be. Gathering her courage, she carried Ping An's box into the living room where her mother was reading. Her heart pounded as she explained everything—the cold night, the injury, and Dr. Chen's help. To her surprise, her mother didn't get angry. Instead, she looked thoughtfully at the sleeping dog and then at her daughter's hopeful face. "I see he's helped you too," she said softly. After a long discussion, they reached an agreement: Ping An could stay in the garage temporarily while Li Yan contacted the foster program.
Paragraph 2:
Watching Ping An happily chasing a ball in the living room, Li Yan felt a warmth spread through her chest. Her father, who had come to visit, was smiling as he watched them play. It turned out that her parents' decision to let Ping An stay wasn't just for her—caring for the dog had become their common ground, helping them communicate better. Ping An had not only found a home but had also helped mend hers. Li Yan realized that sometimes rescue isn't a one-way street; while she offered Ping An safety, he gave her family something even more precious—a new beginning and rediscovered joy.
