蟾宫曲

阿鲁威

理征衣鞍马匆匆。又在关山，鹧鸪声中。三叠《阳关》，一杯鲁酒①，逆旅新丰②。

看五陵③无树起风，笑长安却误英雄。 云树濛濛，春水东流，有似愁浓。

【注释】①鲁酒：春秋时鲁国所酿酒，味薄。②逆旅新丰：唐代名臣马周未做官时客游长安，住在新丰旅舍中，受尽店主白眼。逆旅，旅舍。新丰，在今陕西临潼县东。③五陵：西汉高祖长陵、惠帝安陵、景帝阳陵、武帝茂陵、昭帝平陵，均在长安一带。

小华和他的兴趣小组利用如图所示的滑轮组进行实验，人以600N的力向下拉绕在滑轮组上的绳子的一端，10秒钟绳子下端移动了1.5m，重物上升0.5m，已知该滑轮组的效率为70%（g取10N/kg）。

（1） 画出小华兴趣小组所用滑轮组的绕线情况；
（2） 人的拉力做功的功率是多少？
（3） 被吊起重物的质量是多少？
