Biggie Burger, a new fast food restaurant, will soon be opened in the town. A large group of kids and parents were holding signs shouting outside it yesterday. They were there because hey didn't want the restaurant to open. Never!

“This kind of food is really bad for us!” said Diana,” It’s high in salt, fat, and sugar. it’s unhealthy and we are going to say ’no’ to it!”

“Our town has been a quiet place. Restaurants like this bring people and also a lot of trouble to this area,” said Barbara.” And I’m afraid they will take business away form our local restaurants.”

Other local people disagree .The officials believe that Biggie Burger will bring in huge amounts of money to help improve the town. And 17-year-old Sandy can’t wait for Biggie Burger to open.” I love their hamburgers and fried chicken wings! And I can get a job there.”

Sandy’s dad, a cleaner, agrees,” Biggie Burger’s prices are just right for a family like ours.”

Michael, who owns a toy shop next door to Biggie Burger, is excited, too.” Maybe people who come for a Biggie Burger will spend a few minutes in my store and pick up something.”

The town will hole a meeting on Thursday to hear sides. Everyone is welcome to attend it. Come and voice your opinion!

小题3:Barbara is afraid that fewer people will come to the local restaurants.

小题4:Sandy has found a job in Biggie Burger and loves food there.

小题5: Cleaners like Sandy’s dad in the town can afford the food in Biggie Burger.

小题6: Michael welcomes the opening of Biggie Burger.

小题7:The town doesn’t care about people’s opinions when making a decision.

“三个有利于”的标准指什么？

如图是测定小灯泡额定功率的实物连接图，其中电源是三节新的干电池，灯泡的额定电压是3.8V，其灯丝电阻约为1OΩ，滑动变阻器上标有“1OΩ1A”的字样．（说明：电流表接线柱从左到右为“-”“0.6”“3”；电压表接线柱从左到右为“-”“3”“15”）

（1）请你用笔画线代替导线将电路中未连接的部分连好，使它成为完整的实验电路．

（2）小刚合理地连接好电路，并按正确的顺序操作，但闭合开关后灯不亮，聪明的小刚猜想：

A．可能是灯丝断了B．可能是电流表断路

C．可能是小灯泡短路D．可能是滑动变阻器断路

请你借助图1中的电流表和电压表验证小刚的猜想，将电流表、电压表的示数填表．

猜想	电流表示数/A	电压表示数/V
如果A成立	______	______
如果D成立	______	______

（3）假如电压表0-15V量程已损坏，小刚仍想测出小灯泡的额定功率，请你将小刚设计的电路图画在图2的方框内．

（4）按小刚新设计的电路图调节滑动变阻器，使电压表示数达到______V时，小灯泡就正常发光．此时电流表示数如图3所示，则小灯泡的额定功率是______W．
