So Sarah and her mum said goodbye to the beach and flew away. They flew and flew, until they were out of the cold and back into the warm weather. They flew all the way to Miami, Florida.
There, they found a new beach. It was filled with fish, and there were lots of people to give them sandwiches and chips. Sarah’s mum even found a new roof for them to sleep under.
“I like this other home,” said Sarah. “It is warm, and we have food. This is a nice place too.”
“I told you it would be nice,” said Sarah’s mum. “And when it gets warmer in New York again, we will go back. That is the nice part about being a bird. We can fly to new places whenever we want.”

2、玻尔用量子化轨道解释氢光谱，将量子观念引入原子领域。
3、天然放射现象表明原子核可衰变，说明其有内部结构。
4、康普顿散射证明光子与电子的粒子性，与核式结构无关。
28．【答案】A,D
【知识点】气体的等温变化及玻意耳定律；α粒子的散射；阴极射线与阴极射线管；天然放射现象
【解析】【解答】本题考查阴极射线和α粒子散射实验，天然放射现象和带电粒子在电磁场中的偏转，气体压强随温度的变化关系，会根据题意进行准确分析解答。A．英国物理学家汤姆孙利用图甲所示的气体放电管证实阴极射线是带电粒子流，故A正确；
B．英国物理学家卢瑟福利用图乙所示的α粒子散射实验提出了原子的核式结构模型，故B错误；
