在探究“滑动摩擦力的大小跟哪些因素有关”的过程中，一些同学作出了以下猜想：猜想A滑动摩擦力的大小可能与接触面的粗糙程度有关；猜想B滑动摩擦力的大小可能与接触面间的压力大小有关；为了检验上述有关猜想是否正确，某同学选用了一块底面与各个侧面粗糙程度均相同的长方体木块，并设计了以下实验方案：

步骤1把长方体的木块平放在水平的长木板上，用弹簧测力计水平拉木块沿直线匀速滑动，读出这时弹簧测力计的读数（如图甲）；

步骤2在长方体木块放上砝码（如图乙），用弹簧测力计水平拉木块，使砝码与木块一起沿直线匀速运动，比较“步骤2”与“步骤1”中弹簧测力计读数的大小；

步骤3在水平长木板铺上一层棉布，把木块平放在棉布上（不加砝码），用弹簧测力计水平拉木块沿直线匀速滑动（如图丙），比较“步骤3”与“步骤1”中弹簧测力计读数的大小．

（1）当用弹簧测力计水平拉木块沿直线匀速滑动时，滑动摩擦力的大小就等于弹簧测力计的读数，为什么？

（2）“步骤2”的设计目的，是为了检验上述猜想（A、B）中哪一个的正确与否？

（3）在“步骤2”中，若木块上方砝码的重为0.5牛，当用弹簧测力计水平拉木块沿直线匀速滑动时，则砝码与木块间摩擦力的大小

A．大于0.5牛                  

B．大于零且小于0.5牛

C．等于0.5牛                  

D．等于零．

Twenty-five years and five Oscar nominations later, she (35) a Best Actress Academy Award for her role as Sister Helen Prejean in 1995’s Dead Man Waling, a searing film about capital punishment.
By (36) Sarandon was practiced at using her celebrity to (37) causes close to her heart. (38) , while presenting an award at the 1993 Oscars, she and longtime partner Tim Robbins, an actor and director, took 30 seconds of their podium time to speak on (39) of Haitian refugees with AIDS. "At the (40) of acting and activism is imagination," Sarandon says. "I’ve (41) had the ability to imagine being in someone else’s shoes."
