一、听力理解
短篇新闻
题目：NASA最新火星探测成果
原文：
"NASA announced this morning that its latest Mars rover, 'Voyager-3', has detected traces of organic molecules in the soil of Jezero Crater. The discovery, made using the rover's advanced spectrometers, marks the first time such complex carbon-based compounds have been found in an area once thought to be an ancient lakebed. Scientists believe these molecules could be remnants of microbial life that existed on Mars over 3 billion years ago, though they caution that non-biological processes, such as reactions between water and rock, could also explain the findings."
问题：
What is the main finding of the Mars rover "Voyager-3"?
What does Dr. Elena Morales say about the discovery?
解析：
答案：探测器在杰泽罗陨石坑的土壤中发现了有机分子痕迹。
关键点：原文明确提到 "traces of organic molecules" 和 "Jezero Crater"，需注意专有名词拼写。
答案：这些分子可能是30亿年前火星微生物生命的遗迹，但也可能是水岩反应等非生物过程的结果。
关键点：科学家观点包含两种可能性，需全面概括。
长对话
题目：职业规划咨询
原文：
M: "Hi, Lisa. Did you talk to any companies at the career fair yesterday?"
W: "Yeah, I spoke to a few tech firms. One of them, GreenSoft, is recruiting for a summer internship in data analysis. They said I’d assist with customer behavior research. Sounds interesting, but I’m not sure if my stats skills are good enough."
M: "You took Advanced Statistics last semester, right? And you aced the final. I think you’re qualified."
问题：
What is Lisa considering applying for?
What does the man suggest Lisa highlight in her application?
解析：
答案：GreenSoft公司的数据分析暑期实习。
关键点：对话中明确提到公司名称和职位类型。
答案：她的项目经验和Python认证。
关键点：男士建议强调项目经验(如社交媒体趋势分析)和Python证书。
二、阅读理解
选词填空
原文：
"A new study published in Nature Climate Change reveals that global sea levels could rise by up to 60 centimeters by 2100 if current greenhouse gas emissions remain unchecked. The research, based on satellite data and ice sheet models, highlights that the West Antarctic Ice Sheet is melting faster than previously estimated."
题目：
The study suggests that limiting global warming to 1.5°C could ______ sea level rise to 30 centimeters.
选项：
A. reduce
B. accelerate
C. maintain
D. ignore
答案：A
解析：原文提到 "limiting global warming to 1.5°C... could reduce the sea level rise to 30 centimeters"，直接对应选项A。
长篇阅读
主题：军事技术民用化
原文：
"Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies."
题目：
What can be inferred from the passage?
选项：
A. Military technology has great potential in civilian use.
B. Blue whales are no longer endangered.
答案：A
解析：原文指出海军开始共享水下监听系统，用于民用科研(如追踪鲸鱼、监测火山)，说明军事技术有民用潜力。
三、翻译
原文：
"地球科学家最近宣布，他们首次利用该系统密切监测了一次深海火山喷发，并计划开展类似研究。"
参考译文：
"Earth scientists recently announced that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies."
解析：
"首次利用"译为 "for the first time";
"密切监测"译为 "closely monitoring";
并列结构需用 "and that" 保持语法正确。
四、写作
题目：在线课程调查反馈
要求：讨论在线课程的优缺点并提出建议，字数120-180.
范文：
"Online learning has become increasingly popular, but its effectiveness remains debated. On the positive side, it offers flexibility—students can access materials anytime, balancing studies with personal tasks. High-quality courses from renowned institutions are also widely available. However, drawbacks exist. Limited face-to-face interaction hinders communication, and self-discipline is required, which many students lack. To improve, universities should enhance interactive tools like video conferences and provide training for both students and teachers on online pedagogy. By addressing these issues, online learning can become a more integral part of education."
解析：
结构：分三段(观点引入、优缺点分析、建议);
亮点：使用 "hinders communication" 和 "online pedagogy" 等高级词汇;
逻辑：通过 "however" 和 "to improve" 清晰衔接。
