🤔 Why?
为什么电路和开关这么有趣？
Why is Circuits and Switches interesting?
当开关闭合时，电路形成通路，电流流过灯泡使它发光；当开关断开时，电路断路，灯泡就灭了。

🎯 Fun Challenge
Multiple Choice开关断开时，电路里的灯泡会怎样？
What happens to the light bulb when the switch is open?
💡 想一想刚才读到的内容。 Think about what you just read.
答对了！开关断开时电路断路，电流无法通过，灯泡就熄灭了。 Correct! When the switch is open, the circuit breaks and current cannot flow, so the bulb goes dark.
💭 Think About It
你能举一个生活中电路开关控制的例子吗？
Can you give a real-life example of Circuit Switch Control?
哇！ Wow!
