第二节(满分25分)
47. 阅读下面材料, 根据其内容和所给段落开头语续写两段, 使之构成一篇完整的短文。
On a sunny Friday afternoon, our class was excited about the upcoming school science fair. Mr. Smith, our science teacher, tasked us with creating a unique project to showcase. He divided the class into groups of four and I was teamed up with three other classmates: Alex, Lily, and Tom. We brainstormed ideas, and I proposed a project about the effects of different fertilizers (肥料) on plant growth. Everyone took the idea on board, and we got started right away.
We divided the work. I was in charge of researching different types of fertilizers, Alex was to prepare the plants, Lily would record the data, and Tom was responsible for making the display board. At first, everything went smoothly. I dug deep into various resources, finding detailed information about fertilizers. Alex carefully planted the seeds and took good care of the young plants. The other two also applied themselves to completing their tasks routinely.
However as the days passed, problems began to surface. Tom, who was not very interested in the project from the start, started slacking off (偷懒). He didn’t spend much time on the display board, saying he was too busy with other things. Lily got frustrated because the incomplete display board affected her data organization. Arguments broke out within the group. I was angry with Tom for not completing his duty, and Tom argued that the project wasn’t as important as we thought. Alex tried to calm us down, but the tension was still on.
The science fair was approaching fast, and we were far from ready. With the project in a mess, we all felt stressed and disappointed. Lily even stayed up late trying to reorganize the scattered (零散的) data, but without Tom’s visuals, her charts looked incomplete and confusing. None of us wanted to see our hard work go to waste, but we didn’t know how to solve the problem.

3、安徽初中2025年5月九年级模拟考试生物答案


C、甲中可以通过控制水的流量，控制反应速率，乙中的水有除杂、降温的作用，故正确；
D、供氧器中的固体B是催化剂，不一定是二氧化锰固体，还可能是氧化铁等，故错误；
故选：D。
5．化学兴趣小组开展了“设计和制作简易供氧器”的实践活动。图甲为供氧器的工作原理，下列说法正确的是（　　）
A．要防止输出氧气的管道堵塞，避免引发安全事故
B．制氧剂只能是过氧化氢溶液和二氧化锰
C．加湿过滤仓中水的作用是控制反应速率


综上所述，答案为C。
10．D
A．正反应过程中，涉及到H－H非极性键、C=O极性键断裂，生成H－O、C－O、C－H极性键，无非极性键形成，故A项错误；
B．反应过程中，反应前后气体总质量不变且为密闭容器，体积不变，则气体密度不变，故B项错误；
C．已知该反应为放热反应，断键吸收的总能是小于形成化学键放出的总能量，故C项错误；
D．当3molH2完全转化时消耗二氧化碳的物质的量为1mol，极限转化率为20%，该反应为可逆反应，则转化率小于20%，故D项正确；
故本题选D。
