某同学复习中用图甲所示的电路再次探究串联电路电压的规律,实验时意外发现:“当变阻器滑片P向左移时,两电压表的读数之和减小。”他产生了疑惑,在老师的引导下,知道了用久的普通干电池内部有不可忽略的电阻,可将它看作一个理想电源(电压U恒定,电阻为0)与一个电阻r的串联(图乙所示)。

请你帮他选择适当器材,设计测量干电池电阻r的实验方案。

可供选用的器材:一个电压表,符合实验要求的已知阻值的定值电阻R1、R2(R1≠R2),导线和开关若干,一节旧干电池。

要求R1、R2在同一电路中不能同时工作。请完成:

(1)画出实验电路图;

(2)根据你设计的电路写出主要的实验步骤和需测量的物理量:

(3)写出电阻r的数学表达式(用已知量和测量量表示)。

When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at "bed and breakfast" houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.
"We didn’t stay at bed and breakfast houses," they said, "because we found that most families were away on holiday. "
I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought "VACANCIES" meant "holidays", because the Spanish word for "holiday" is "vacation". So they did not go to house where the sign outside said "VACANCIES", which in English means there are free rooms. Then my friends went to house where the sign said " NO VACANCIES", because they thought this meant the people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels!
We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word "DIVERSION" means fun. In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word "DIVERSION" on a road sign, they thought they were going to have fun. Instead, the road is blocked by a crowd.
English people have problems too when they learn foreign languages. Once in Paris when someone offered me some more coffee, I said "Thank you" in French. I meant that I would like some more. However, to my surprise the coffee pot was taken away! Later I found out that "Thank you" in French means "No, thank you".

I was surprised when the coffee pot was taken away because I ______.

A.hadn’t finished drinking my coffee
B.was expecting another cup of coffee
C.meant that I didn’t want any more
D.was always understood
