1选择题
To protect the local wetland ecosystem, a nature reserve _______ (establish) in this area by the government since 2020, and it has become a haven for migratory birds.
- A. has been established
- B. was established
- C. is established
- D. had been established
答案：A
解析：本题考查现在完成时的被动语态 (have/has been done) 在具体语境中的应用。关键解题步骤：1. 分析主语‘a nature reserve’与动词‘establish’之间是被动关系（保护区被建立）；2. 时间状语‘since 2020’明确表示动作从过去某一时间开始，持续到现在并对现在有影响（已成为候鸟天堂），符合现在完成时的用法；3. 主语为单数，应用‘has’。综合以上，应选‘has been established’。易错点：1. 混淆时态，误选一般过去时‘was established’（B项），忽略了‘since’的延续性；2. 忽略被动语态，误用主动形式；3. 主谓不一致，错用‘have’。故选A。
2选择题
The newly established Wetland Park, _______ a variety of endangered birds find shelter, has become a popular destination for eco-tourists and researchers alike, highlighting the importance of biodiversity conservation in urban areas.
- A. which
- B. where
- C. when
- D. that
答案：B
解析：本题考查非限制性定语从句的关系词选择。主句为‘The newly established Wetland Park has become a popular destination...’，结构完整。逗号后的从句‘_______ a variety of endangered birds find shelter’是对先行词‘Wetland Park’的补充说明，为非限制性定语从句。分析从句结构：从句主语为‘a variety of endangered birds’，谓语为‘find’，宾语为‘shelter’，句子成分完整，不缺少主语或宾语，因此不能使用关系代词which或that。从句需要一个表示地点的状语，说明鸟类‘在湿地公园里’找到庇护，故应使用关系副词where。易错点：学生可能忽略从句成分完整的判断，误选关系代词which；或对非限制性定语从句的逗号标志不敏感。故选B。

阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Many people believe that if they had more time, they would be able to pursue their passions and lead a more fulfilling life. However, research suggests that this is not always the case. A study conducted by a university psychology department found that individuals who were given more free time did not necessarily report higher levels of happiness. In fact, the study revealed a "sweet spot" of around 2-5 hours of free time per day. Beyond this amount, many participants began to feel a lack of structure and purpose, which often led to feelings of restlessness and even guilt. The researchers concluded that while some free time is essential for well-being, too much can be counterproductive. This finding challenges the common assumption that more leisure time automatically equals greater happiness. It highlights the importance of balancing free time with meaningful activities, whether they are work-related, social, or personal hobbies. Therefore, rather than simply wishing for more time, it might be more beneficial to focus on how we use the time we already have.
36. According to the study, what happens when people have too much free time?
- A. They feel more creative.
- B. They experience increased anxiety.
- C. They become more productive at work.
- D. They develop stronger social bonds.
答案：B
解析：本题为阅读理解细节题，考查对文章关键信息的理解。文章第三、四句指出，研究发现，每天超过2-5小时的自由时间，许多参与者开始感到缺乏结构和目的，这常常导致不安感（restlessness）甚至负罪感（guilt）。B选项“他们经历更多的焦虑”（anxiety）与文中restlessness and guilt含义一致，是最佳答案。
A选项“他们感到更有创造力”在文中未提及。
C选项“他们在工作中变得更有效率”与文中结论相反，过多自由时间可能适得其反（counterproductive）。
D选项“他们发展出更强的社会纽带”在文中未提及。
故选B。

阅读下面关于极地生态保护的短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
The preservation of polar regions is not just an environmental concern; it is a matter of global significance. As temperatures rise, the melting of ice sheets and glaciers accelerates, leading to rising sea levels that threaten coastal communities worldwide. Furthermore, the loss of sea ice disrupts the habitat of iconic species like polar bears and seals, which rely on it for hunting and breeding. Scientists have observed that _______ is causing a decline in the population of certain fish species, which in turn affects the entire polar food web. This intricate chain reaction underscores the urgent need for international cooperation to reduce carbon emissions and protect these fragile ecosystems.
Which of the following best completes the blank in the passage?
- A. the increasing acidity of the ocean
- B. the overfishing in Arctic waters
- C. the growth of tourism in Antarctica
- D. the expansion of polar research stations
答案：A
解析：本题考查在语篇中运用名词性从句（此处为表语从句）的能力，并结合环保情境。空格处需要一个在从句中作主语的连接词，且其内容需与上下文逻辑一致。A项“the increasing acidity of the ocean”（海洋酸度增加）是导致鱼类种群下降的科学原因，与后文“affects the entire polar food web”形成因果链，符合语境。B项“过度捕捞”虽可能影响鱼类，但前文已提及气温上升和海冰融化，此处应延续气候变化的影响，而非引入新的人为因素。C、D项与鱼类种群下降无直接逻辑关联。易错点在于忽略从句成分（需一个作主语的名词性成分）和上下文因果逻辑，而误选B。故选A。
5填空题
阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
The global effort to protect endangered species requires not only scientific research but also widespread public participation. ________ (involve) local communities in conservation projects is crucial, as their traditional knowledge and daily practices often hold the key to sustainable solutions. For instance, in some regions, ________ (protect) forests has been achieved through community-based management systems, ________ villagers monitor wildlife and report illegal logging. However, a major challenge remains: balancing economic development with ecological preservation. It is no use ________ (ignore) the needs of the people living in these areas; instead, finding ways to ________ (harmony) their livelihoods with conservation goals is essential for long-term success.
答案：1. Involving 2. protecting 3. where 4. ignoring 5. harmonize
解析：本题综合考查非谓语动词（动名词作主语）、定语从句（关系副词）以及固定句型。1. 分析句子结构，空格处缺主语，且表示一般性、习惯性活动‘让当地社区参与’，应用动名词Involving作主语。2. 空格处作句子的主语，表示‘保护森林’这一泛指行为，应用动名词protecting作主语。3. 分析句子结构，主句为‘in some regions, protecting forests has been achieved...’，逗号后的从句‘________ villagers monitor...’修饰先行词‘systems’，且从句成分完整（主语villagers，谓语monitor），缺少地点状语，表示‘在这些系统中’，故用关系副词where引导非限制性定语从句。4. 句型‘It is no use/good...’后应接动名词，故填ignoring。5. 空格前为‘to’，此处是动词不定式符号，后接动词原形；根据句意‘使他们的生计与保护目标和谐共处’，动词harmonize符合语境。易错点：第1、2小题易误用不定式作主语；第3小题易忽略从句成分完整而误填which；第4小题易在固定句型中误用不定式。

Dear fellow students,
As part of our school's initiative to build a greener campus, I'd like to share some thoughts on waste sorting and resource recycling.
答案：Dear fellow students,
As part of our school's initiative to build a greener campus, I'd like to share some thoughts on waste sorting and resource recycling.
Currently, some students still throw all waste into the same bin, making it difficult to recycle useful materials. This not only wastes resources but also pollutes the environment.
To improve this, I suggest that we first place clearly labeled recycling bins for paper, plastic, and cans in classrooms and hallways. This would make sorting convenient and efficient. Second, why not organize a weekly 'green class' competition? The class that recycles the most waste could win a prize, which would motivate everyone to participate actively.
By taking these small steps, we can contribute to a sustainable future. Let's work together to make our campus cleaner and greener!
解析：本题综合考查建议信的写作能力，特别是结合‘自然生态与环境保护’情境提出具体、可行的建议。易错点包括：1. 建议空泛，如只说‘我们应该好好分类’，没有具体措施；2. 结构混乱，缺少开头、正文和结尾的层次；3. 语气不当，使用命令式而非委婉的建议句型（如‘I suggest that...’ ‘Why not...?’ ‘It would be a good idea to...’）。学生需注意内容紧扣‘校园垃圾分类’主题，建议需有理由支撑，并发出呼吁。

阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
In recent years, there has been a growing awareness of the importance of protecting wetlands, which are often called the "kidneys of the earth" due to their vital role in purifying water. A project ___36___ (launch) in a coastal city aims to restore a degraded wetland ecosystem. The area, once ___37___ (pollute) by industrial discharge, is now undergoing a transformation. Experts ___38___ (concern) with environmental science have designed a plan to reintroduce native plants. These plants, known for their strong root systems, can effectively absorb harmful substances from the water and soil. The project's success depends largely on the ___39___ (cooperate) of local communities. Volunteers, many of ___40___ are students, have been actively involved in planting and monitoring. Their efforts are ___41___ (gradual) bringing life back to the wetland. It is a reminder that if we take immediate action, damaged ecosystems can be ___42___ (heal). The ___43___ (responsible) for protecting our planet lies with every individual. This initiative not only benefits the environment but also provides a valuable lesson in ___44___ (sustain) development for the younger generation. The renewed wetland now serves as a habitat for various birds, proving that human intervention, when guided by science, can lead to positive ___45___ (out).
答案：36. launched 37. polluted 38. concerned 39. cooperation 40. whom 41. gradually 42. healed 43. responsibility 44. sustainable 45. outcomes
解析：
36. 考查过去分词作后置定语。project与launch之间是被动关系（项目被发起），且句子已有谓语动词aims，故用过去分词launched作定语，相当于which was launched。
37. 考查过去分词作表语。area与pollute之间是被动关系（区域被污染），且空格前有was，构成被动语态或系表结构，故用polluted。
38. 考查过去分词作后置定语。experts与concern之间是被动关系（专家被关注/涉及到），且be concerned with是固定短语，意为“与…有关”，此处作定语，故用concerned。
39. 考查名词。空格前有定冠词the，后有介词of，需要名词形式。动词cooperate的名词形式是cooperation，意为“合作”。
40. 考查定语从句关系代词。先行词是volunteers，且空格前有介词of，指代人，在介词后作宾语，故用whom。
41. 考查副词。修饰动词短语bringing life back，需要副词形式。形容词gradual的副词形式是gradually。
42. 考查被动语态中的过去分词。主语ecosystems与heal之间是被动关系（生态系统被治愈），且情态动词can be后需接过去分词构成被动语态，故用healed。
43. 考查名词。空格前有定冠词The，后有介词for，需要名词形式。形容词responsible的名词形式是responsibility，意为“责任”。
44. 考查形容词作定语。修饰名词development，需要形容词形式。动词sustain的形容词形式是sustainable，意为“可持续的”。
45. 考查名词。空格前有形容词positive，需要名词形式。动词out的名词形式是outcome，意为“结果”，且根据语境应用复数outcomes。
解析：本题为语法填空，综合考查非谓语动词（过去分词作定语和表语）、构词法（动词变名词、形容词变副词、动词变形容词）、定语从句关系词和被动语态。情境为自然生态保护，贴近考点。易错点：1. 第36、37、38题均涉及过去分词，但句子成分不同（定语 vs. 表语），需准确判断动词与所修饰名词的逻辑关系及句子结构。2. 第39、43题考查动词变名词，需注意不规则变化（cooperate→cooperation）和拼写（responsibility）。3. 第40题在“介词+关系代词”结构中，指人应用whom，易误用who或that。4. 第42题在情态动词后需用过去分词，易误用原形。

阅读下面关于海洋塑料污染的短文，然后回答问题。
Plastic pollution in the oceans has become a critical global issue. Millions of tons of plastic waste enter the sea each year, harming marine life and ecosystems. Recent studies indicate that plastic debris can be found even in the most remote areas of the ocean, from the surface to the deep sea floor. Microplastics, tiny fragments less than 5mm in size, are particularly concerning as they are easily ingested by a wide range of marine organisms, from plankton to whales. This not only threatens individual species but also disrupts the entire food chain. Scientists are now investigating innovative solutions, such as developing biodegradable plastics and improving waste management systems on land. However, public awareness and individual responsibility are equally vital in combating this problem.
1. Identify the topic sentence of the paragraph and state the main idea it conveys.
2. Analyze the structure of the paragraph. What is the problem presented, what supporting details are given, and what solution is suggested?
3. The text mentions "microplastics... are easily ingested by a wide range of marine organisms." Explain the significance of this statement in the context of the paragraph's argument about the severity of plastic pollution.
答案：1. Topic sentence: "Plastic pollution in the oceans has become a critical global issue." Main idea: It introduces the central theme that ocean plastic pollution is a severe and widespread problem.
2. Structure analysis:
- Problem: Plastic pollution is a critical global issue, with millions of tons entering the sea annually, harming marine life and ecosystems.
- Supporting details: Plastic debris is found everywhere, including remote areas. Microplastics are especially dangerous because they are ingested by many organisms, disrupting the food chain.
- Suggested solution: Scientists are developing biodegradable plastics and improving waste management. Public awareness and responsibility are also crucial.
3. The statement highlights the pervasive and insidious nature of microplastics. Their tiny size allows them to be consumed by organisms at all levels of the marine food web, from the smallest to the largest. This illustrates how the pollution doesn't just affect isolated species but has a cascading effect on the entire ecosystem, thereby strengthening the paragraph's argument that plastic pollution is a severe, systemic threat.
解析：本题综合考查主旨识别、篇章结构分析和细节理解能力。第1题要求准确找出主题句并概括主旨，易错点是将支撑细节（如具体数据）误认为主旨。第2题考查议论文结构，需清晰区分问题、论据和解决方案，学生易遗漏解决方案部分或概括不全。第3题要求分析细节的论证作用，需理解“ingested by a wide range of marine organisms”这一细节如何支撑“破坏整个食物链”这一论点，从而论证问题的严重性。解题关键在于结合上下文进行逻辑推理。
