17．Why do we make New Year’s resolutions (不超过10个词)
18．What is the main idea of the passage (不超过10个词)
阅读下面的短文，按要求回答问题或翻译画线部分。
Peter’s birthday wish
Peter was a 12-year-old boy. He was the only child in his family.
His birthday was coming up soon. He wished he could have a bike. But his family didn’t have much money. His father said they were too (太) poor to buy him a bike.
A week later, when Peter was on his way home from school, he saw a boy riding a bike. But the bike was too small for the boy. Suddenly (突然地) the boy fell down (摔倒) and got hurt (受伤). Peter went over to him and asked others to help him to send the boy to the hospital. The boy’s parents arrived at the hospital later and gave Peter some money to thank him for his help. But Peter didn’t take it. Later, the boy’s parents knew that Peter didn’t have a bike. They gave the child’s bike to Peter. They said, “The bike is too (太) small for our child and that is why he fell down.”

6、哈九中2024级高二学年下学期4月阶段性测试数学试题

B、核反应过程中引发剧烈能量释放，则该核反应会出现质量亏损，故B正确；
、根据质量数和电荷数守恒可知质子数，质量数，生成的新核为碳核，故CD错误。
8.【答案】
【解析】核反应都遵循质量数守恒和电荷数守恒，与是否发生质量亏损无关，选项A错误
中等大小核的比结合能较大，轻核聚变是向中等大小核变化，所以核的比结合能增大，则核的比结合能大于核的比结合能，核的核子数大于核的核子数，结合能等于比结合能与核子数的乘积，则核的结合能也大于核的结合能，选项B错误
轻核聚变过程中参与核反应的核子数为个，平均每个核子放出的能量为，选项C正确
轻核聚变时生成的核的比结合能大，比结合能越大越稳定，不会发生衰变反应，所以不具有放射性，选项D错误。
