【导语】本文是一篇夹叙夹议文。文章通过讲述一个海洋科学家意外拍摄到罕见小章鱼的故事，引出了科学领域中类似的幸运发现，并进一步扩展到日常生活中因幸运而获得成功的事例。
1.主旨大意题。根据最后一段“These stories show that while hard work is important, sometimes the best things happen when we aren’t even looking for them. Life’s most wonderful surprises often come when we least expect them.(这些故事表明，尽管努力很重要，但有时最美好的事情会在我们毫无期待时发生。生命中最奇妙的惊喜，往往出现在我们最意想不到的时刻。)”以及全文内容可知，全文通过三个故事：海洋科学家意外拍到稀有章鱼、弗莱明偶然发现青霉素、汤姆因陌生人故事获得创作灵感，共同讲述了“意外发现可能带来重大突破”的核心观点。故选B。
2.细节理解题。根据文章第二段“When he returned, he saw that mold (霉) had grown on it — but instead of throwing it away, he noticed the bacteria near the mold had died. This lucky mistake led to the discovery of penicillin, the first antibiotic (抗生素) medicine.(当他回来时，发现培养皿上长出了霉菌——但他没有将其扔掉，而是注意到霉菌附近的细菌已经死亡。这个幸运的失误促成了青霉素的发现，这是人类历史上第一种抗生素药物。)”可知，弗莱明未加盖培养皿后，霉菌生长，且霉菌周围的细菌死亡。故选B。
3.推理判断题。根据最后一段“These stories show that while hard work is important, sometimes the best things happen when we aren’t even looking for them. Life’s most wonderful surprises often come when we least expect them.(这些故事表明，尽管努力很重要，但有时最美好的事情会在我们毫无期待时发生。生命中最奇妙的惊喜，往往出现在我们最意想不到的时刻。)”以及全文内容可知，全文通过三个案例反复强调“意外时刻带来重要发现”，如科学家意外拍到章鱼、弗莱明的偶然疏忽、汤姆的随机聆听，均印证“重要发现常发生在预料之外”的结论。故选D。
4.推理判断题。根据最后一段“These stories show that while hard work is important, sometimes the best things happen when we aren’t even looking for them. Life’s most wonderful surprises often come when we least expect them.(这些故事表明，尽管努力很重要，但有时最美好的事情会在我们毫无期待时发生。生命中最奇妙的惊喜，往往出现在我们最意想不到的时刻。)”以及全文内容可知，作者通过三个故事强调“意外与运气”在发现和成功中的作用，但并非否定努力，而是突出“敞开心态接纳意外”的重要性。选项C“Luck often favors those who are open to surprises.(运气常眷顾乐于拥抱惊喜的人)”既体现“运气”的存在，又隐含“开放心态”的必要，精准契合作者观点。故选C。
【答案】5. A 6. A 7. C 8. D
【导语】本文是一篇说明文。主要介绍了最近一项研究表明，高强度的脑力劳动，如备考，会意外增加食物渴望，而短暂的运动休息可能有助于减少这种因学习引起的食物渴望。
5.细节理解题。根据第一段中的“Scientists explain that when we concentrate hard, our brains burn through energy reserves quickly. Since the brain can’t store much fuel, it signals the body to seek calories — even when we haven’t moved much physically. This may explain why many students find themselves reaching for snacks during long study sessions. (科学家解释说，当我们集中精力时，我们的大脑会迅速消耗能量储备。由于大脑无法储存太多能量，它会向身体发出寻求热量的信号——即使我们的身体并没有太多运动。这也许可以解释为什么许多学生在长时间的学习过程中会伸手去拿零食)”可知，高强度学习期间食物渴望增加的主要原因是大脑在集中注意力时迅速消耗能量。故选A项。
6.细节理解题。根据第二段中的“Dr. Sarah Miller, lead researcher, explains that physical activity boosts circulation, sending more blood sugar and oxygen to the brain. “When the brain gets this energy boost through exercise, it may stop sending urgent hunger signals,” she says. (首席研究员莎拉·米勒博士解释说，体育活动能促进血液循环，向大脑输送更多的血糖和氧气。“当大脑通过运动获得这种能量提升时，它可能会停止发出紧急的饥饿信号，”她说。)”可知，运动通过改善大脑的血液流动来帮助减少因学习引起的食物渴望。故选A项。
7.主旨大意题。根据第一段第一句“A recent study reveals that intense mental tasks, like studying for tests, can unexpectedly increase food cravings (渴望). (最近的一项研究表明，高强度的脑力劳动，如备考，会意外增加食物渴望。)”和第二段第一句“Researchers from Harvard University and Boston College designed an experiment to test whether short exercise breaks could reduce these study-induced cravings. (哈佛大学和波士顿学院的研究人员设计了一项实验，以测试短暂的锻炼休息是否能减少这些因学习引起的渴望)”以及下文对实验的介绍可知，文章主要讲述了脑力劳动会增加饥饿感，但运动可能有助于缓解。故选C项
8.细节理解题。根据最后一段最后一句“The team plans to investigate whether outdoor exercise provides additional benefits compared to indoor workouts. (研究小组计划调查户外运动是否比室内运动提供额外的好处)”可知，未来研究的方向是研究户外运动与室内运动。故选D项。人教版选择性必修2 Unit3 短语句子检测2

三、 阅读
阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
C
A marine scientist was swimming near a colorful coral reef, hoping to photograph a rare kind of seahorse. After hours of searching with no luck, she was about to give up when suddenly, a bright seahorse appeared right in front of her. Excited, she quickly took the picture. Later, when she checked the photo, she made an amazing discovery — just behind the seahorse, hidden in the coral, was an even rarer small octopus! She hadn’t noticed it during her dive, but her camera had accidentally captured one of the ocean’s hardest-to-find creatures. It was a moment of pure luck.
Such happy accidents also happen in science. In the 1920s, a scientist named Alexander Fleming was studying bacteria when he forgot to cover one of his experiment dishes. When he returned, he saw that mold (霉) had grown on it — but instead of throwing it away, he noticed the bacteria near the mold had died. This lucky mistake led to the discovery of penicillin, the first antibiotic (抗生素) medicine. Fleming wasn’t trying to find a cure, but his accident changed medical history forever.
Even in daily life, luck can bring great things. My friend Tom, who loves music, was having trouble writing song lyrics. One day, while sitting in a park, he heard two strangers telling an interesting story. Their words gave him the perfect idea for his song—and that song later became his first big success!
These stories show that while hard work is important, sometimes the best things happen when we aren’t even looking for them. Life’s most wonderful surprises often come when we least expect them.
1. What is the main idea of the passage
A. The importance of careful observation in marine biology.
B. Unexpected discoveries can lead to significant breakthroughs.
C. The process of developing new medicines in the 1920s.
D. How to become a successful musician through luck.
2. What happened when Alexander Fleming left his experiment dish uncovered
A. The bacteria grew faster than expected.
B. The mold killed the surrounding bacteria.
C. The dish became polluted and was thrown away.
D. He had to restart his experiment from the beginning.
3. What can be inferred from the passage about accidental discoveries
A. Tom deliberately listened to strangers to get song ideas.
B. Fleming was initially worried about the mold growing there.
C. The importance of these findings immediately became apparent.
D. Important discoveries often happen during unexpected moments.
4. Which of the following sayings can best summarize what the author thinks about
A. Wisdom comes from careful consideration.
B Success belongs to those who plan carefully.
C. Luck often favors those who are open to surprises.
D. No joyful moment lasts forever.
D
A recent study reveals that intense mental tasks, like studying for tests, can unexpectedly increase food cravings (渴望). Scientists explain that when we concentrate hard, our brains burn through energy reserves quickly. Since the brain can’t store much fuel, it signals the body to seek calories — even when we haven’t moved much physically. This may explain why many students find themselves reaching for snacks during long study sessions.
Researchers from Harvard University and Boston College designed an experiment to test whether short exercise breaks could reduce these study-induced cravings. Dr. Sarah Miller, lead researcher, explains that physical activity boosts circulation, sending more blood sugar and oxygen to the brain. “When the brain gets this energy boost through exercise, it may stop sending urgent hunger signals,” she says.
The study involved 40 university students who first completed challenging math problems for 30 minutes. Afterwards, half the participants rested while the other half did 15 minutes of mixed exercises (jumping jacks, squats, and light jogging). When offered snacks later, the exercise group ate 25% less than the resting group and reported feeling more satisfied.
However, the research had some limitations. It only measured immediate food intake after one study session, and didn’t track whether participants compensated (补偿) by eating more later. Also, all exercises were moderate-intensity (中等强度); the team isn’t sure if easier activities like stretching would have the same effect.
“While more research is needed,” Dr. Miller notes, “our findings suggest that short activity breaks could help students avoid unnecessary snacking during cram sessions (临时抱佛脚).” The team plans to investigate whether outdoor exercise provides additional benefits compared to indoor workouts.
5. What is the primary cause of increased food cravings during intense studying
A. The brain consumes energy rapidly during focus.
B. The body mistakes mental work for physical labor.
C. Blood sugar drops sharply during concentration.
D. Students snack more when feeling stressed.
6. How does exercise help reduce study-induced cravings
A. It improves blood flow to the brain. B. It reduces stress levels significantly.
C. It delays hunger temporarily. D. It replaces the need for calorie intake.
7. What does the passage mainly tell us
A. All brain work leads to weight gain.
B. Stress causes food cravings during tests.
C. Mental effort increases hunger but exercise may help.
D. Students should exercise instead of eating snacks.
8 What future research direction is suggested
A. Testing if stretching reduces cravings. B. Comparing snack types during studying.
C. Tracking students’ sleep patterns. D. Studying outdoor vs indoor exercise.人教版选择性必修2 Unit3 单词检测1
