例句：蚓无爪牙之利，筋骨之强。

在如图所示的电路中，电源电压为9V且保持不变，电流表的规格为“0～3A”，电压表的规格为“0～15V”，灯泡上标有“6V 6W”字样，灯泡中的电流随电压变化的关系如图所示．试求：

(1)灯泡正常发光时的电阻．
(2)当电流表示数为0.4A时，电压表的示数．
(3)灯泡正常发光时滑动变阻器消耗的电功率．

增加：在缺词处加一个漏字符号(Λ)，并在其下面写出该加的词。

删除：把多余的词用斜线(＼)划掉。

修改：在错的词下划一横线，并在该词下面写出修改后的词。

Dear Joy,

    How are you doing? Here is an exciting news for you. There will be an invention competition in our school in the 20th of October. However, there is a rule the participants shall be in a group. But I'd like to invite you to be my partners.

    I know that you have been longed to design a tiny cooler that people can wear around the wrist. I think it will be a wonderfully idea for the competition. We can make a small air conditioner to controlling the temperature of the wearer.

    How do you think of my suggestion? Looking forward to you reply.
