Global Connections
Students from different countries helped each other learn. Maria from Spain shared: “We taught our Beijing teammates about Spanish writing apps.” All teams stayed in the host city, experiencing local culture through tech-themed tours.
China’s Double Success
Chinese students won 12 medals (3 gold). Team Shanghai created an AI system predicting forest dangers with 95% accuracy. “We trained it using satellite pictures, “their team leader said,” it helps save trees “Equally important, China also showed that it could do a great job hosting this big world event.
Beyond Competition
The event featured technology workshops (研讨会) where world-class AI scientists shared knowledge with participants (参与者). Organizers started a website to keep students working together. They also announced a new online platform to continue collaborations, declaring: “Our mission is to keep young innovators (创新者) connected year-round.”

[1]据题可知，无风时OC是竖直的，连入电路的电阻是AB段，有风时，OC杆偏转一定的角度，连入电路的电阻变为BP段，连入电路的电阻随风的大小而改变，风力测定仪相当于滑动变阻器。
[2][3]风越强，OC杆偏转的角度越大，BP段越小，电阻变小，电源电压不变，电路中的电流变大，灯泡越亮；但若将小灯泡换成电流表后，由于该电路中只有滑动变阻器一个电阻，所以若风力过大，可能会导致电路发生短路，因此不能将灯泡换成电流表。
6.(1)B (2)变大 变暗
（1）为保护电路，闭合开关前，应将滑片移动到阻值最大处，即B端。
（2）[1][2]由图可知，灯泡与滑动变阻器串联接入电路中，将滑片向右移动，滑动变阻器接入电路中的电阻丝变长，阻值将变大，由，电路中电流变小，灯泡变暗。
7.(1)左 (2)滑动变阻器连接的是下面两个接线柱 滑动变阻器连接的是上面两个接线柱
（1）为了保护电路，连接实物时，开关应当断开，滑片P应移动到阻值最大处，即最左端。
