山东省济南市第一中学2024-2025学年高一下学期3月学情检测英语试题
一、阅读理解（本大题共5小题）
From going to work to traveling, here are some backpacks you can use in several different situations.
SZLX backpack
This backpack is described as “designed for travel” and you can see why—as unzipped and open, it looks a bit like a carry-on bag. It has two zip pockets and an inside compartment (隔层). With a shoe compartment and a bag for wet clothes, it is a great choice for traveling and regular use.
Della Gao backpack
This backpack will have you feeling safe, with lockable zips (拉链). It has three main compartments and at 17 inches, has a large overall space for keeping important items. It’s a wise choice for business travel, university or if you’re going on holiday with high-value items.
Lekesky backpack
Looking like a cross between a lunch bag and a backpack, the Lekesky bag is actually a bit of both, with two pockets alongside a main compartment. The bag also has a separate lunch compartment, able to store food for nine hours with an ice bag. The bag comes in black/white as well as green/white.
Maxtop backpack
If what you’re after in a backpack is a lot of space, then this bag will be the one for you. It comes with metal zippers and a USB port, plus it can be folded up when not in use. It also has a D-ring for you to hang a key or other items if desired.

A mother of nine who started medical school when her youngest child was 4 years old graduated with her degree and plans to be a neurosurgeon (神经外科医生).
Sarah Merrill, now 41, said her journey to medical school began at age 17. She then met her husband and got married. Merrill first thought about going to school part-time to get a degree, but later she decided to follow her dream of attending medical school. Certainly, it was a challenge. Speaking of her successfully returning to university, Merrill thought it was credited to her family largely. “When I was accepted at Mayo Clinic Alix School of Medicine, we moved from Pennsylvania to Arizona,” said Merrill, who is moving to Indiana with her family to begin her residency (实习期) in neurosurgery. “In fact, they volunteered these movements. I know it was tough for all of us.”
Merrill and her children often have “homework parties” where they study for their own courses. Merrill’s choice has given a stimulus to her children. Merrill felt touched knowing her 11-year-old daughter wants to become a surgeon and overhearing her son tell his friends his mom’s going to be a cool brain surgeon, though he doesn’t understand that really.
Merrill’s next step into a neurosurgery residency will take her into a male-dominated field where only 5% of board certified neurosurgeons are women. Dr. Michele Halyard at Mayo Clinic Alix School of Medicine said Merrill was known as a focused student. Halyard said, “If you can deal with nine children and keep your reason, the residency should be a piece of cake because no amount of stress will make you fail.”
Merrill had considered choosing a more family-friendly specialty, but, again, chose to dream big and follow her original pursuit. It’s the same advice she would give to all. “Set the goal that is what you’re really enthusiastic about, and it helps to think small. If you know what your priorities are, focus on the next step. Then you’ll get where you want to go.”
4．Why does Merrill speak of their movements
A．To show the support of her family.
B．To stress her determination to be a doctor.
C．To reflect difficulties in attending college.
D．To describe the process of pursuing her dream.
5．What does the underlined word “stimulus” mean in paragraph 3
A．Entertainment. B．Inspiration.
C．Commitment. D．Confusion.
6．What does Halyard mean in paragraph 4
A．Merrill will have more stress to handle.
B．Staying focused and sensible is key to success.
C．Being Mom makes Merrill a better doctor.
D．She is confident of Merrill’s being a neurosurgeon.
7．What does Merrill suggest at last
A．Starting with small things.
B．Getting your priorities right.
C．Being true to your passion.
D．Having the courage to dream big.
Birds that migrate (迁徙) long distances tend to be more likely than others to break up with their partners, according to an analysis of 232 species conducted by Sun Yat-sen University.
About 90 percent of bird species are socially monogamous (单一配偶的), which means once they form pairs, they will stay together for life. However, some do end up getting divorced and move onto new partners.
To identify reasons that lead to birds’ breakups, Liu Yang at Sun Yat-sen University in China and his colleagues studied 232 species in one of the world's largest bird databases, Birds of the World. They found that species that migrate particularly long distances to obtain food typically have higher rates of breaking up.
Great blue herons, for example, migrate more than 3,000 kilometers and have a divorce (分离) rate of 100 percent. “This may be because travelling further makes it harder for a pair to return home at the same time,” says Liu Yang. “If you’re the one who gets back first, it’s risky waiting for your partner because you don’t know if it’ll show up because it may have died or been blown off course,” Liu adds. “Finding a new partner may seem a safer bet even if it requires energy to please a new mate.”
Liu and his team members acknowledge that it makes sense for birds with long migrations to have higher divorce rates, but there are exceptions.
Black-tailed godwits, for example, migrate more than 1,000 kilometers from Iceland to the UK or southwest Europe each year but have relatively low divorce rates. This seems to be due to a super ability to keep pace with their partners. Although members of a pair will follow separate migration paths and typically end up more than 900 kilometers away from each other, they are somehow able to return to Iceland at almost the same time, which reduces the risk of breakups. “But most birds are not able to do that — it’s pretty amazing.” Liu concludes.
8．What can be inferred from paragraph 2
A．Few bird species are devoted to their partners.
B．Most bird species tend to have only one partner.
C．Most bird species have higher rates of breaking up.
D．Most bird species have more than one partner for life.
9．Why do great blue herons have a divorce rate of 100 percent
A．They get tired of their partners.
B．They are impatient with waiting.
C．They choose different migration routes.
D．It is safer to move onto a new partner.
10．What can we learn about black-tailed godwits in the last paragraph
A．They set a good example of romance.
B．They have a higher divorce rate than great blue herons.
C．The nearly same returning time reduces the risk of divorce.
D．It is typical to migrate at the same speed with their partners.
11．Which of the following is the best title for the text
A．Reasons for Bird Migration
B．Migration Linked to Bird Divorce
C．Bird Migration with Long Distances
D．Birds with High Rates of Divorce
Giving silkworm silk a metallic bath may make the strands (丝线) both strong and solid, scientists reported on October 6 in Matter. The work is the latest in a decades-long pursuit of creating fibers as strong, lightweight and biodegradable as spider silk. If scientists can mass-produce such material, the potential uses will range from the biomedical to the athletic. Sewing up wounds, even sporting equipment could get a significant improvement.
Hunting for enough silky material to make these super strong products has been a big barrier. Silk from silkworms is simple to harvest, but not all that strong. And spider silk, the gold standard for hand-spun strength and toughness, is not exactly easy to collect. “Unlike silkworms, spiders cannot be farmed due to their nature,” wrote study coauthor Lin Zhi, a structural biologist at Tianjin University.
“Scientists around the world have tried to spin strong strands in the lab using silkworm cocoons. The first step is to take off the silk’s sticky outer coating. Scientists can do this by boiling the fibers in a chemical bath, but that can be like taking a knife to silk proteins. If the proteins get too damaged, it’s hard for scientists to make them into high-quality strands,” said Chris Holland, a material scientist at the University of Sheffield.
Lin’s team tried gentler approaches, one of which used lower temperatures and the papaya enzyme (木瓜酵素) to help dissolve the silk’s coating. That seemed to work. They don’t have little pieces of silk protein. That’s huge because the bigger the proteins that remain, the stronger the fibers are going to be. After some processing steps, the researchers bathed the pressed silk in a solution containing zinc and iron ions (锌离子和铁离子). That was why some of the strands were so strong — Lin’s team detected zinc ions in the finished fibers.
But Holland wasn’t so sure. “The team’s real innovation may be that they’ve managed to untwist silk in a less damaging way. The silk protein remains in a good state,” he said. “In my mind, that’s a major step forward.”
12．Why is creating super strong silk worth the long-term pursuit
A．It can be mass-produced.
B．It promotes athletic training.
C．It might have wide applications.
D．It is potentially environmentally friendly.
13．What makes it hard to collect desirable natural silk according to Lin
A．The absence of silkworm data.
B．The low quality of spider silk.
C．The poor harvest of silkworm silk.
D．The insufficient supply of spider silk.
14．How did Lin’s team make the silk fiber strong
A．By enhancing its protein.
B．By removing its coating.
C．By bathing it in metallic liquid.
D．By squeezing it firmly in a tube.
15．In what aspect did Lin’s team make breakthrough according to Holland
A．Mass-producing silk.
B．Analyzing silk scientifically.
C．Creating silk of superior quality.
D．Processing silk in a safer method.
Is Exercise the Key to Better Health
We’ve all heard that regular exercise is vital for staying healthy. 16 Research shows a clear answer: yes, especially if you mix up your activities to target different fitness areas. By doing so, you can keep your body in top shape and prevent health issues from arising.
·How exercise boosts(促进)heart and lung health.
17 If you do a balanced routine that includes cardio(有氧运动), strength training, and flexibility exercises, your body gets better at using oxygen. When you exercise regularly, your heart and lungs work more efficiently, pumping oxygen-rich blood to your muscles and organs. This can lead to a lower risk of heart disease and improved respiratory(呼吸的)function.
· 18
Lately, scientists have been exploring how physical activity affects our mental health. Wellness centers worldwide are now offering Mental Health Fitness Programs. These programs let people take part in exercises designed to enhance both physical and mental health. Regular exercise has been shown to greatly lower symptoms of depression and anxiety, leading to a better mood overall. It’s like a natural antidepressant(抗抑郁药)that doesn’t come with negative side effects.
·How physical activity improves lifelong well- being.
Staying active is a basis for a high-quality life. Exercise not only maintains your physical health and manages your emotions but also enhances your overall well-being. From hiking to swimming, physical activities can reduce stress, lift your spirits, and give you the energy to fully engage in the things you love. By keeping fit, you’re investing in a lifestyle that’s filled with energy. 19
While exercise is great, it’s important to pay attention to your body and avoid pushing too hard, which can lead to injuries. 20 This helps your body handle the workout and recover properly, ensuring you can continue to enjoy the benefits of exercise without interruption. In summary, making exercise a regular part of your life can lead to a happier, healthier you.
A．The influence of exercise on physical health.
B．But is it really the best solution to better health, as many experts suggest
C．The impact of exercise on mental health.
D．This active lifestyle is also marked by a sense of accomplishment and joy.
E．To stay safe and healthy, always warm up before you exercise and cool down afterward.
F．Another big plus of regular exercise is that it can lift your spirits.
G．Exercise strengthens your heart and lungs.

【分析】本文是一篇记叙文。Sarah Merrill是一位有九个孩子的妈妈，在她最小的孩子只有4岁时，Merrill决定追逐梦想上医学院。在历尽艰难获得医学学位后，Merrill选择步入只有5%的女性医生取得职业资格证书的神经外科，成为一名神经外科医生。
【解析】4．推理判断题。根据第二段的“Speaking of her successfully returning to university, Merrill thought it was credited to her family largely ... In fact, they volunteered these movements.(谈到她成功重返大学，Merrill认为这在很大程度上归功于她的家庭。Merrill说：“当我被梅奥诊所阿利克斯医学院录取时，我们从宾夕法尼亚州搬到了亚利桑那州。”她将和家人一起搬到印第安纳州，开始她的神经外科住院医生实习期。事实上，这些搬家是他们自愿的)”可知，Merrill认为她能成功回到校园主要归功于她的家人，为了方便她学习，Merrill一家从宾夕法尼亚州搬到亚利桑那州，现在为了她的工作又要搬到印第安纳州，并且这些搬家是她的家人主动提出的。由此可推断，Merrill提到他们的搬家是为了说明家人的支持。故选A。
5．词义猜测题。根据画线词后的“knowing her 11-year-old daughter wants to become a surgeon and overhearing her son tell his friends his mom’s going to be a cool brain surgeon, though he doesn’t understand that really(得知她11岁的女儿想成为一名外科医生，无意中听到她的儿子告诉他的朋友，他的妈妈将成为一名很酷的脑外科医生，尽管他真的不明白)”可知，Merrill的11岁的女儿想成为一名外科医生，她的儿子告诉朋友们他的妈妈会成为一名很酷的脑外科医生，由此可推断，Merrill决定成为一名神经外科医生的选择激励了孩子们。stimulus意为“激励”，inspiration“鼓舞人心的人（或事物）”与画线词含义相近。故选B。
6．推理判断题。根据第四段中的“If you can deal with nine children and keep your reason, the residency should be a piece of cake because no amount of stress will make you fail.(如果你能同时照顾9个孩子并保持理智，实习应该是小菜一碟，因为再大的压力也不会让你失败)”可知，Halyard认为如果你能应对九个孩子并保持理智，那么神经外科医生的实习期应该是小菜一碟，因为即使再多的压力也不会让你失败。由此可推断，她对Merrill通过实习成为神经外科医生充满信心。故选D。
7．细节理解题。根据最后一段中的“... chose to dream big and follow her original pursuit. It’s the same advice she would give to all. ‘Set the goal that is what you’re really enthusiastic about(选择了远大的梦想，并遵循了她最初的追求。这也是她给所有人的建议。‘设定你真正感兴趣的目标)”可知，Merrill建议遵循最初的追求，设定真正热爱的目标。故选C。
【答案】8．B 9．D 10．C 11．B
【分析】这是一篇说明文，文章主要讲述一项研究发现：长途迁徙的鸟类往往比其他鸟类更有可能与伴侣分手。
【解析】8．推理判断题。根据第二段中“About 90 percent of bird species are socially monogamous (单一配偶的), which means once they form pairs, they will stay together for life.(大约90%的鸟类是一夫一妻制的，这意味着它们一旦结成一对，就会一生在一起)”可知，大多数鸟类往往只有一个配偶，故选B。
9．细节理解题。根据第四段中“Finding a new partner may seem a safer bet even if it requires energy to please a new mate.(找一个新伴侣似乎是更安全的选择，即使取悦新伴侣需要精力)”可知，大蓝鹭的离婚率为100%，是因为换一个新的伴侣对它们来说更安全，故选D。
10．细节理解题。根据最后一段中“Black-tailed godwits, for example, migrate more than 1,000 kilometers from Iceland to the UK or southwest Europe each year but have relatively low divorce rates. This seems to be due to a super ability to keep pace with their partners. Although members of a pair will follow separate migration paths and typically end up more than 900 kilometers away from each other, they are somehow able to return to Iceland at almost the same time, which reduces the risk of breakups.(例如，黑尾塍鹬每年从冰岛迁移1000多公里到英国或欧洲西南部，但离婚率相对较低。这似乎是由于他们与伴侣保持同步的超强能力。虽然一对的迁徙路线各不相同，而且通常会在相距900多公里的地方结束，但它们几乎可以同时返回冰岛，这就降低了它们分手的风险)”可知，一对黑尾塍鹬虽然迁徙路线不同，但它们几乎在同一时间返回，这降低了它们离婚的风险，故选C。
11．主旨大意题。根据全文内容，结合第一段“Birds that migrate (迁徙) long distances tend to be more likely than others to break up with their partners, according to an analysis of 232 species conducted by Sun Yat-sen University.(根据中山大学对232种鸟类的分析，长途迁徙的鸟类比其他鸟类更容易与伴侣分手)”和下文分析长途迁徙导致鸟类离婚率高的原因可知，文章主要讲述一项研究发现：长途迁徙的鸟类往往比其他鸟类更有可能与伴侣分手，B项“迁徙与鸟类离婚有关”为最佳标题，故选B。
【答案】12．C 13．D 14．C 15．D
【分析】这是一篇说明文，科学家在10月6日的《物质》杂志上报道称，将蚕丝放入金属浴中可能会使其变得既结实又坚固。
【解析】12．细节理解题。根据第一段中“If scientists can mass-produce such material, the potential uses will range from the biomedical to the athletic. Sewing up wounds, even sporting equipment could get a significant improvement.(如果科学家能够大量生产这种材料，其潜在用途将从生物医学到体育运动。缝合伤口，甚至运动器材都能得到显著改善)”可知，制造超级坚固的蚕丝值得长期追求是因为它可能有广泛的应用，故选C。
13．细节理解题。根据第二段中“And spider silk, the gold standard for hand-spun strength and toughness, is not exactly easy to collect. ‘Unlike silkworms, spiders cannot be farmed due to their nature,’ wrote study coauthor Lin Zhi, a structural biologist at Tianjin University.(而蜘蛛丝作为手工纺丝强度和韧性的黄金标准，并不容易收集。‘不像蚕，蜘蛛的性质决定了它们不能被人工饲养。’天津大学结构生物学家、该研究的合著者Lin Zhi写道)”可知，在Lin看来，很难收集到理想的天然丝是因为蜘蛛丝供应不足，故选D。
14．细节理解题。根据第一段中“Giving silkworm silk a metallic bath may make the strands (丝线) both strong and solid, scientists reported on October 6 in Matter.(科学家在10月6日的《物质》杂志上报道称，将蚕丝放入金属浴中可能会使其变得既结实又坚固)”和第四段中“After some processing steps, the researchers bathed the pressed silk in a solution containing zinc and iron ions (锌离子和铁离子). That was why some of the strands were so strong — Lin’s team detected zinc ions in the finished fibers.(经过一些处理步骤后，研究人员将压下的丝绸浸泡在含有锌离子和铁离子的溶液中。这就是为什么一些纤维如此坚固的原因——Lin的团队在成品纤维中检测到锌离子)”可知，Lin的团队将蚕丝浸泡在金属液体中使丝绸纤维变得结实，故选C。
15．细节理解题。根据最后一段“But Holland wasn’t so sure. ‘The team’s real innovation may be that they’ve managed to untwist silk in a less damaging way. The silk protein remains in a good state,’ he said. ‘In my mind, that’s a major step forward.’(但Holland并不那么肯定。‘该团队真正的创新可能是，他们设法以一种损害较小的方式解开丝绸。蛛丝蛋白仍处于良好状态，’他说。‘在我看来，这是向前迈出的一大步。’)”可知，Holland认为，Lin的团队在用更安全的方法加工丝绸方面取得了突破，故选D。

A mother of nine who started medical school when her youngest child was 4 years old graduated with her degree and plans to be a neurosurgeon (神经外科医生).
Sarah Merrill, now 41, said her journey to medical school began at age 17. She then met her husband and got married. Merrill first thought about going to school part-time to get a degree, but later she decided to follow her dream of attending medical school. Certainly, it was a challenge. Speaking of her successfully returning to university, Merrill thought it was credited to her family largely. “When I was accepted at Mayo Clinic Alix School of Medicine, we moved from Pennsylvania to Arizona,” said Merrill, who is moving to Indiana with her family to begin her residency (实习期) in neurosurgery. “In fact, they volunteered these movements. I know it was tough for all of us.”
Merrill and her children often have “homework parties” where they study for their own courses. Merrill’s choice has given a stimulus to her children. Merrill felt touched knowing her 11-year-old daughter wants to become a surgeon and overhearing her son tell his friends his mom’s going to be a cool brain surgeon, though he doesn’t understand that really.
Merrill’s next step into a neurosurgery residency will take her into a male-dominated field where only 5% of board certified neurosurgeons are women. Dr. Michele Halyard at Mayo Clinic Alix School of Medicine said Merrill was known as a focused student. Halyard said, “If you can deal with nine children and keep your reason, the residency should be a piece of cake because no amount of stress will make you fail.”
Merrill had considered choosing a more family-friendly specialty, but, again, chose to dream big and follow her original pursuit. It’s the same advice she would give to all. “Set the goal that is what you’re really enthusiastic about, and it helps to think small. If you know what your priorities are, focus on the next step. Then you’ll get where you want to go.”
4．Why does Merrill speak of their movements
A．To show the support of her family.
B．To stress her determination to be a doctor.
C．To reflect difficulties in attending college.
D．To describe the process of pursuing her dream.
5．What does the underlined word “stimulus” mean in paragraph 3
A．Entertainment. B．Inspiration.
C．Commitment. D．Confusion.
6．What does Halyard mean in paragraph 4
A．Merrill will have more stress to handle.
B．Staying focused and sensible is key to success.
C．Being Mom makes Merrill a better doctor.
D．She is confident of Merrill’s being a neurosurgeon.
7．What does Merrill suggest at last
A．Starting with small things.
B．Getting your priorities right.
C．Being true to your passion.
D．Having the courage to dream big.
Birds that migrate (迁徙) long distances tend to be more likely than others to break up with their partners, according to an analysis of 232 species conducted by Sun Yat-sen University.
About 90 percent of bird species are socially monogamous (单一配偶的), which means once they form pairs, they will stay together for life. However, some do end up getting divorced and move onto new partners.
To identify reasons that lead to birds’ breakups, Liu Yang at Sun Yat-sen University in China and his colleagues studied 232 species in one of the world's largest bird databases, Birds of the World. They found that species that migrate particularly long distances to obtain food typically have higher rates of breaking up.
Great blue herons, for example, migrate more than 3,000 kilometers and have a divorce (分离) rate of 100 percent. “This may be because travelling further makes it harder for a pair to return home at the same time,” says Liu Yang. “If you’re the one who gets back first, it’s risky waiting for your partner because you don’t know if it’ll show up because it may have died or been blown off course,” Liu adds. “Finding a new partner may seem a safer bet even if it requires energy to please a new mate.”
Liu and his team members acknowledge that it makes sense for birds with long migrations to have higher divorce rates, but there are exceptions.
Black-tailed godwits, for example, migrate more than 1,000 kilometers from Iceland to the UK or southwest Europe each year but have relatively low divorce rates. This seems to be due to a super ability to keep pace with their partners. Although members of a pair will follow separate migration paths and typically end up more than 900 kilometers away from each other, they are somehow able to return to Iceland at almost the same time, which reduces the risk of breakups. “But most birds are not able to do that — it’s pretty amazing.” Liu concludes.
8．What can be inferred from paragraph 2
A．Few bird species are devoted to their partners.
B．Most bird species tend to have only one partner.
C．Most bird species have higher rates of breaking up.
D．Most bird species have more than one partner for life.
9．Why do great blue herons have a divorce rate of 100 percent
A．They get tired of their partners.
B．They are impatient with waiting.
C．They choose different migration routes.
D．It is safer to move onto a new partner.
10．What can we learn about black-tailed godwits in the last paragraph
A．They set a good example of romance.
B．They have a higher divorce rate than great blue herons.
C．The nearly same returning time reduces the risk of divorce.
D．It is typical to migrate at the same speed with their partners.
11．Which of the following is the best title for the text
A．Reasons for Bird Migration
B．Migration Linked to Bird Divorce
C．Bird Migration with Long Distances
D．Birds with High Rates of Divorce
Giving silkworm silk a metallic bath may make the strands (丝线) both strong and solid, scientists reported on October 6 in Matter. The work is the latest in a decades-long pursuit of creating fibers as strong, lightweight and biodegradable as spider silk. If scientists can mass-produce such material, the potential uses will range from the biomedical to the athletic. Sewing up wounds, even sporting equipment could get a significant improvement.
Hunting for enough silky material to make these super strong products has been a big barrier. Silk from silkworms is simple to harvest, but not all that strong. And spider silk, the gold standard for hand-spun strength and toughness, is not exactly easy to collect. “Unlike silkworms, spiders cannot be farmed due to their nature,” wrote study coauthor Lin Zhi, a structural biologist at Tianjin University.
“Scientists around the world have tried to spin strong strands in the lab using silkworm cocoons. The first step is to take off the silk’s sticky outer coating. Scientists can do this by boiling the fibers in a chemical bath, but that can be like taking a knife to silk proteins. If the proteins get too damaged, it’s hard for scientists to make them into high-quality strands,” said Chris Holland, a material scientist at the University of Sheffield.
Lin’s team tried gentler approaches, one of which used lower temperatures and the papaya enzyme (木瓜酵素) to help dissolve the silk’s coating. That seemed to work. They don’t have little pieces of silk protein. That’s huge because the bigger the proteins that remain, the stronger the fibers are going to be. After some processing steps, the researchers bathed the pressed silk in a solution containing zinc and iron ions (锌离子和铁离子). That was why some of the strands were so strong — Lin’s team detected zinc ions in the finished fibers.
But Holland wasn’t so sure. “The team’s real innovation may be that they’ve managed to untwist silk in a less damaging way. The silk protein remains in a good state,” he said. “In my mind, that’s a major step forward.”
12．Why is creating super strong silk worth the long-term pursuit
A．It can be mass-produced.
B．It promotes athletic training.
C．It might have wide applications.
D．It is potentially environmentally friendly.
13．What makes it hard to collect desirable natural silk according to Lin
A．The absence of silkworm data.
B．The low quality of spider silk.
C．The poor harvest of silkworm silk.
D．The insufficient supply of spider silk.
14．How did Lin’s team make the silk fiber strong
A．By enhancing its protein.
B．By removing its coating.
C．By bathing it in metallic liquid.
D．By squeezing it firmly in a tube.
15．In what aspect did Lin’s team make breakthrough according to Holland
A．Mass-producing silk.
B．Analyzing silk scientifically.
C．Creating silk of superior quality.
D．Processing silk in a safer method.
Is Exercise the Key to Better Health

From hiking to swimming, physical activities can reduce stress, lift your spirits, and give you the energy to fully engage in the things you love. By keeping fit, you’re investing in a lifestyle that’s filled with energy. 19
While exercise is great, it’s important to pay attention to your body and avoid pushing too hard, which can lead to injuries. 20 This helps your body handle the workout and recover properly, ensuring you can continue to enjoy the benefits of exercise without interruption. In summary, making exercise a regular part of your life can lead to a happier, healthier you.
A．The influence of exercise on physical health.
B．But is it really the best solution to better health, as many experts suggest

There were many strong runners in my grade, and some of them had more experience and skills than me. One of them was Leo. He was my friend, but also my biggest competitor. He was confident that he would win the marathon too.
The day of the race finally came. I was nervous but excited. I put on my running shoes and headed to the starting line. I saw my competitors, some of them looking confident, some of them looking worried. Leo was among them, smiling and waving at me. I tried to relax myself and pay attention to my own running. The coach gave us some last-minute advice and encouragement. He told us to do our best and not give up.
The whistle blew and we were off. I rushed ahead, trying to get a good position. I felt the wind in my face. I heard the cheers of the crowd and the footsteps of the other runners. I kept running, pushing myself to do my best.
After running for a while, I realized that I was in the lead. I couldn’t believe it. I had never been in this situation before. But then I also felt a sense of fear. What if I couldn’t keep it up What if someone caught up with me What if I fell
I tried to shake off (摆脱) these negative thoughts and pay attention to the finish line. But it was getting harder and harder. My legs were burning and my heart was pounding.

It’s a wise choice for business travel, university or if you’re going on holiday with high-value items.(这个背包有可锁的拉链，会让你有安全感。它有三个主隔间，有17英寸的空间，整体空间很大，可以存放重要物品。对于商务旅行、上大学或带着贵重物品去度假来说，这是一个明智的选择)”可知，Della Gao backpack最适合携带贵重物品。故选A项。
2．细节理解题。根据Lekesky backpack下的“Looking like a cross between a lunch bag and a backpack, the Lekesky bag is actually a bit of both, with two pockets alongside a main compartment.

The bag comes in black/white as well as green/white.(Lekesky包看起来像是午餐袋和背包的混合体，实际上两者兼而有之，在主隔层旁边有两个口袋。这个袋子还有一个单独的午餐隔间，可以用冰袋储存9个小时的食物。这个包有黑色/白色和绿色/白色两种颜色)”可知，Lekesky backpack很适合保存食物。故选B项。
3．推理判断题。根据第一段“From going to work to traveling, here are some backpacks you can use in several different situations.(从上班到旅行，这里有一些你可以在不同场合使用的背包)”可知，本文主要介绍一些可以在不同场合使用的背包，而背包和生活有关。由此推知，本文有可能出现在报纸的生活方式板块。故选C项。
【答案】4．A 5．B 6．D 7．C
【分析】本文是一篇记叙文。Sarah Merrill是一位有九个孩子的妈妈，在她最小的孩子只有4岁时，Merrill决定追逐梦想上医学院。在历尽艰难获得医学学位后，Merrill选择步入只有5%的女性医生取得职业资格证书的神经外科，成为一名神经外科医生。
【解析】4．推理判断题。根据第二段的“Speaking of her successfully returning to university, Merrill thought it was credited to her family largely ... In fact, they volunteered these movements.(谈到她成功重返大学，Merrill认为这在很大程度上归功于她的家庭。Merrill说：“当我被梅奥诊所阿利克斯医学院录取时，我们从宾夕法尼亚州搬到了亚利桑那州。”她将和家人一起搬到印第安纳州，开始她的神经外科住院医生实习期。事实上，这些搬家是他们自愿的)”可知，Merrill认为她能成功回到校园主要归功于她的家人，为了方便她学习，Merrill一家从宾夕法尼亚州搬到亚利桑那州，现在为了她的工作又要搬到印第安纳州，并且这些搬家是她的家人主动提出的。由此可推断，Merrill提到他们的搬家是为了说明家人的支持。故选A。
5．词义猜测题。根据画线词后的“knowing her 11-year-old daughter wants to become a surgeon and overhearing her son tell his friends his mom’s going to be a cool brain surgeon, though he doesn’t understand that really(得知她11岁的女儿想成为一名外科医生，无意中听到她的儿子告诉他的朋友，他的妈妈将成为一名很酷的脑外科医生，尽管他真的不明白)”可知，Merrill的11岁的女儿想成为一名外科医生，她的儿子告诉朋友们他的妈妈会成为一名很酷的脑外科医生，由此可推断，Merrill决定成为一名神经外科医生的选择激励了孩子们。stimulus意为“激励”，inspiration“鼓舞人心的人（或事物）”与画线词含义相近。故选B。
6．推理判断题。根据第四段中的“If you can deal with nine children and keep your reason, the residency should be a piece of cake because no amount of stress will make you fail.(如果你能同时照顾9个孩子并保持理智，实习应该是小菜一碟，因为再大的压力也不会让你失败)”可知，Halyard认为如果你能应对九个孩子并保持理智，那么神经外科医生的实习期应该是小菜一碟，因为即使再多的压力也不会让你失败。由此可推断，她对Merrill通过实习成为神经外科医生充满信心。故选D。
7．细节理解题。根据最后一段中的“... chose to dream big and follow her original pursuit. It’s the same advice she would give to all. ‘Set the goal that is what you’re really enthusiastic about(选择了远大的梦想，并遵循了她最初的追求。这也是她给所有人的建议。‘设定你真正感兴趣的目标)”可知，Merrill建议遵循最初的追求，设定真正热爱的目标。故选C。

9．细节理解题。根据第四段中“Finding a new partner may seem a safer bet even if it requires energy to please a new mate.(找一个新伴侣似乎是更安全的选择，即使取悦新伴侣需要精力)”可知，大蓝鹭的离婚率为100%，是因为换一个新的伴侣对它们来说更安全，故选D。
10．细节理解题。根据最后一段中“Black-tailed godwits, for example, migrate more than 1,000 kilometers from Iceland to the UK or southwest Europe each year but have relatively low divorce rates. This seems to be due to a super ability to keep pace with their partners. Although members of a pair will follow separate migration paths and typically end up more than 900 kilometers away from each other, they are somehow able to return to Iceland at almost the same time, which reduces the risk of breakups.(例如，黑尾塍鹬每年从冰岛迁移1000多公里到英国或欧洲西南部，但离婚率相对较低。这似乎是由于他们与伴侣保持同步的超强能力。虽然一对的迁徙路线各不相同，而且通常会在相距900多公里的地方结束，但它们几乎可以同时返回冰岛，这就降低了它们分手的风险)”可知，一对黑尾塍鹬虽然迁徙路线不同，但它们几乎在同一时间返回，这降低了它们离婚的风险，故选C。
11．主旨大意题。根据全文内容，结合第一段“Birds that migrate (迁徙) long distances tend to be more likely than others to break up with their partners, according to an analysis of 232 species conducted by Sun Yat-sen University.(根据中山大学对232种鸟类的分析，长途迁徙的鸟类比其他鸟类更容易与伴侣分手)”和下文分析长途迁徙导致鸟类离婚率高的原因可知，文章主要讲述一项研究发现：长途迁徙的鸟类往往比其他鸟类更有可能与伴侣分手，B项“迁徙与鸟类离婚有关”为最佳标题，故选B。

Sewing up wounds, even sporting equipment could get a significant improvement.(如果科学家能够大量生产这种材料，其潜在用途将从生物医学到体育运动。缝合伤口，甚至运动器材都能得到显著改善)”可知，制造超级坚固的蚕丝值得长期追求是因为它可能有广泛的应用，故选C。
13．细节理解题。根据第二段中“And spider silk, the gold standard for hand-spun strength and toughness, is not exactly easy to collect. ‘Unlike silkworms, spiders cannot be farmed due to their nature,’ wrote study coauthor Lin Zhi, a structural biologist at Tianjin University.(而蜘蛛丝作为手工纺丝强度和韧性的黄金标准，并不容易收集。‘不像蚕，蜘蛛的性质决定了它们不能被人工饲养。’天津大学结构生物学家、该研究的合著者Lin Zhi写道)”可知，在Lin看来，很难收集到理想的天然丝是因为蜘蛛丝供应不足，故选D。
14．细节理解题。根据第一段中“Giving silkworm silk a metallic bath may make the strands (丝线) both strong and solid, scientists reported on October 6 in Matter.(科学家在10月6日的《物质》杂志上报道称，将蚕丝放入金属浴中可能会使其变得既结实又坚固)”和第四段中“After some processing steps, the researchers bathed the pressed silk in a solution containing zinc and iron ions (锌离子和铁离子). That was why some of the strands were so strong — Lin’s team detected zinc ions in the finished fibers.(经过一些处理步骤后，研究人员将压下的丝绸浸泡在含有锌离子和铁离子的溶液中。这就是为什么一些纤维如此坚固的原因——Lin的团队在成品纤维中检测到锌离子)”可知，Lin的团队将蚕丝浸泡在金属液体中使丝绸纤维变得结实，故选C。
15．细节理解题。根据最后一段“But Holland wasn’t so sure. ‘The team’s real innovation may be that they’ve managed to untwist silk in a less damaging way. The silk protein remains in a good state,’ he said. ‘In my mind, that’s a major step forward.’(但Holland并不那么肯定。‘该团队真正的创新可能是，他们设法以一种损害较小的方式解开丝绸。蛛丝蛋白仍处于良好状态，’他说。‘在我看来，这是向前迈出的一大步。’)”可知，Holland认为，Lin的团队在用更安全的方法加工丝绸方面取得了突破，故选D。

56．【答案】I felt like giving up. With these negative thoughts almost overwhelming me, so worn-out was I that my legs got limp and my lung seemed to be about to explode. Naturally, my pace slowed down. With the sound of other competitors’ footsteps coming closer and closer to me, a sense of hopelessness and despair settled over me. “You’ll lose your lead in no time,” an inner voice reminded. I couldn’t help looking back, only to find that Leo was only a few steps away from me.
