1选择题
The old man ________ by the river every morning is a retired scientist who studies wetland birds.
- A. is seen
- B. seeing
- C. seen
- D. is seeing
答案：C
解析：本题考查非谓语动词作定语。句意为“每天早晨在河边被看到的那位老人是一位研究湿地鸟类的退休科学家。”主语The old man与动词see之间是被动关系（被看到），且此处需要非谓语形式作后置定语，相当于定语从句who is seen。过去分词seen表被动和完成，符合语境。A项是谓语形式，会导致句子有两个谓语；B项表主动；D项表主动进行。故选C。
2选择题
—Do you know ________ the panda protection center? —Next Friday. I'm looking forward to it.
- A. when will we visit
- B. when we will visit
- C. when we visited
- D. when did we visit
答案：B
解析：本题考查宾语从句的语序和时态。答语Next Friday表示将来时间，说明从句动作发生在将来，应用一般将来时。宾语从句必须用陈述语序，即“引导词+主语+谓语”。A、D项是疑问语序，错误；C项是过去时，与将来时间不符。故选B。
3填空题
Many rare animals ________ (save) in this national park since the government took action.
答案：have been saved
解析：本题考查现在完成时的被动语态。时间状语since...表示动作从过去持续到现在，应用现在完成时；主语Many rare animals与动词save之间是被动关系（被拯救），因此需用现在完成时的被动语态（have/has been done）。主语为复数，故用have been saved。易错点：漏写been或误用过去时。
4解答题
根据汉语提示完成句子（每空一词）。
据报道，未来几年将会有更多的树木被种植在我们城市。
It's reported that more trees ________ ________ in our city in the future.
答案：will be planted
解析：本题考查一般将来时的被动语态。时间状语in the future提示用一般将来时；主语more trees与动词plant之间是被动关系（被种植），因此用一般将来时的被动语态（will be done）。易错点：漏写be或误用主动语态。
5解答题
将下面两个句子合并为一个含定语从句的复合句。
The river is clean now. We used to swim in it when we were young.
答案：The river in which we used to swim when we were young is clean now. 或 The river which/that we used to swim in when we were young is clean now.
解析：本题考查定语从句的构成。先行词是The river，在从句中作介词in的宾语。关系词可以用“介词+which”结构（in which），也可以用which或that（介词in置于句末）。合并时需注意主句The river is clean now是主干，从句作后置定语修饰The river。易错点：关系词误用where（先行词在从句中作宾语，不作地点状语）或语序混乱。
6解答题
阅读下面短文，根据短文内容回答问题。
The Yangtze River is the longest river in China. It provides water for millions of people and is home to many special animals, like the Chinese sturgeon (中华鲟). However, pollution and overfishing have made it difficult for these animals to survive. To protect the Yangtze River, the Chinese government has set up nature reserves and carried out a ten-year fishing ban. Scientists are also working to release more young fish into the river. Thanks to these efforts, the water quality has improved and the number of some fish has increased.
Question: Why has the Chinese government carried out a ten-year fishing ban in the Yangtze River?
答案：To protect the Yangtze River and the special animals (like the Chinese sturgeon) in it. / Because pollution and overfishing have made it difficult for these animals to survive, so the government wants to protect the river and its ecosystem.
解析：本题考查基于阅读材料的信息提取和归纳能力。答案需定位到短文后半部分，直接原因是为了保护长江及其生态系统（特别是像中华鲟这样的特殊动物）。回答时需涵盖“保护”这一核心目的，并可适当提及背景（污染和过度捕捞导致生存困难）。易错点：只回答“禁止捕鱼”而忽略保护目的，或答案过于简略不完整。
7解答题
根据情境，用所给动词的正确形式填空。
A: Hi, Tom. I heard you went to the countryside last weekend. What did you do there?
B: Yes. We ________ (help) the farmers plant trees. It was a meaningful experience.
A: Sounds great! ________ you ever ________ (be) to a tree-planting event before?
B: No, never. But I ________ (learn) a lot about trees since then. I think everyone should do something for the environment.
答案：helped; Have...been; have learned
解析：本题综合考查动词时态在对话中的应用。第一空，根据问句的过去时态went和答语的was，可知描述过去发生的动作，用一般过去时helped。第二空，询问“你以前参加过植树活动吗？”，强调从过去到现在的经历，用现在完成时Have...been。第三空，since then（从那以后）是现在完成时的标志，表示从过去持续到现在的动作或状态，用have learned。易错点：时态判断不准，特别是since与现在完成时的搭配。

Dear neighbors,
I'm Li Hua. I'm glad to share what I do for a greener life.
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
答案：Dear neighbors,
I'm Li Hua. I'm glad to share what I do for a greener life.
First, I try to save water in my daily life. For example, I turn off the tap while brushing my teeth and reuse water for watering plants. This helps save our precious water resources. Second, I always sort the garbage carefully before throwing it away. Recyclable things like paper and plastic bottles are put into the right bins. This reduces pollution and makes recycling easier.
Small actions can make a big difference. I hope everyone will join us and do something for our environment. Let's work together to make our community cleaner and greener!
Yours,
Li Hua
解析：本题考查综合语言运用能力，需围绕“绿色生活”主题，结合提示要点进行写作。1. 内容方面：需明确写出两件具体环保事例（如节约用水、垃圾分类），并简要说明其好处。2. 结构方面：应分段落阐述，开头引出话题，中间分点说明，结尾发出呼吁。3. 语言方面：需使用正确的时态（一般现在时为主），并恰当运用连接词（First, Second, For example等）使文章连贯。易错点：遗漏提示要点；事例描述空洞不具体；时态或拼写错误。
