测量“小灯泡的电功率”。小灯泡的额定电流为0.3 A，灯丝阻值在10Ω一15 Ω之间。   所提供的器材有：电流表、电压表、电源（电压恒为6 V)、开关各一个，滑动变阻器 (“5Ω 2A”、“20Ω  1A”）两个，导线若干

(1)图是小明没有连接完的实物电路，请你用笔画线代替导线将实物图补充完整。

（2）小明选用的滑动变阻器的规格为          。

（3）闭合开关，移动滑片，当电流表的示数为0.3 A时，电压表的示数如图19所示，读数为         V，小灯泡的额定功率为     W。

（4）小红没用电压表，但多用了一个开关，其它器材与小明的相同，也测出了小灯泡的额定功率。请在虚线框内画出她设计的电路图，并写出实验步骤及测定额定功率的表达式。实验步骤：

     Neighborhoods aren't like they used to be. Sometimes neighbors are complete strangers, even after years

of living yards away. Believe it or not, neighborhoods were once tight-knit communities full of supportive,

friendly and familiar faces. Can they be that way again? You don't have to be an experienced social director

to build bonds in your neighborhood. If you're not happy with the social dynamic in your community, start

making a change today.

     The term "social life" has taken on new meaning, especially for our kids. What was once defined as actual

interaction (e.g. face-to-face) now often refers to the number of Facebook friends or Twitter followers we

can collect. Our social lives have essentially turned inside out, with the focus now being on cyber-space rather

than on reality. "Children play indoors instead of out; most don't even take walks through their streets

anymore," says Jaymes Ian Woode, a relationship counselor. "Moat have grown accustomed to living without

meaningful friendships."

     Change has to start somewhere, and most neighborhoods don't have an official party planner. “To create

change in neighborhoods, it often only takes one person who is willing to reach out," says Woode. "One

person can knock on a neighbor's door and find those who also want to open up. As most salespeople know,

after enough knocks, you are bound to make a sale." Yes, it takes courage and you'll probably have to

overcome some skepticism (怀疑) towards your friendly attitude, but it will be worth it when you actually learn

the names of the people who live around you.

     Susanne Alexander, a relationship coach, recounts some of the ways she has successfully connected with

her neighbors in recent years. "I feel safer and less isolated knowing that I have at least some connection to the

people who live near me," she says. Perhaps her experience will inspire you:

     * Meet neighbors at civic (市民的) events or start an in-home spiritual group.

     * Connect over yard advice or repairs that need cooperation.

     * Exchange numbers with elderly neighbors in case of an emergency.

     * Bring the Sunday comics over to cheer up a neighbor going through a hard time.
