I think the Buddy Club is great. I really enjoy talking with the older students about school life and growing up. They can tell me a lot. One student told me how he relaxed (放松) before exams. Another student told me about great websites about learning History and English.

The Buddy Club is also a good place to just forget about school altogether! One of the older students taught us origami (日本折纸). We made paper planes, birds and hats together.

The table tennis tournament（锦标赛) was a great idea. I didn’t do very well, but I learnt a lot from watching the doubles tournament won by a fourteen-year-old girl and a seventeen-year-old boy.

Last year, we had the annual (每年的) Buddy Club Picnic. Everyone enjoyed the games we played. After I learnt how to fish, I caught two fish in the lake. I think it might be a good idea to change the Buddy Club Picnic to a weekend camping trip. We could learn how to put up (架起) tents (帐篷) and how to find our way through a forest. Many of the older students know how to do this already, and I think they would like to teach the younger students.

I want to say again how much I enjoy the club. When I’m older, I will make friends with younger students. Then, I can tell them all about school life and growing up.

学习了欧姆定律之后，老师引导同学们结合串联电路中电流、电压的特点推导出“串联电路中的总电阻等于各个串联导体的电阻之和．”你能利用滑动变阻器（铭牌上标有50Ω 1A）、两个定值电阻（5Ω和10Ω）、三节干电池、电压表、电流表、开关、导线等器材验证这个结论的正确性么？请你帮助小明同学完成这个实验的设计．

（1）画出电路图，并在右图中对照电路图用笔画线代替导线将没有连接完的实物电路连接好（导线不允许交叉且电流表的量程选取要适当）．

（2）若闭合开关后发现电流表有示数，而电压表无示数，则出现该现象的原因可能示下面哪一种情况？______（只填字母序号即可）．

A、滑动变阻器某处断路              B、只有R₁被短路

C、只有R₂被短路                    D、电压表的某一个接线柱接触不良．
