He was stuck at the bottom in mud(泥).Two hours later, a Ventura County Fire Department rescue(救援) team pulled Sparks to safety. His foot was badly hurt. “Well,I am home after a great trip,” Sparks said. “It is so bad. And I thank all the wonderful friends. I’m sure I’ll get well soon.”When Sparks mowed the grass, he saw a part of sinking(下沉) ground. He tapped(轻敲) it with his foot and the ground gave way.The accident began. His daughter Merrilee Kaszacs said that no one knew Sparks was in the well. About 30 minutes later, Robin Reyes came. She heard the cry for help after she parked her car. “I could not see him,” Reyes said. “I could only hear his voice coming from the hole and he told me it was about 20 to 25 feet down.”During the rescue, Sparks dug himself out of the thick mud with a shovel(铲子).

These people are killed or hurt in road accidents.There are rules to make the roads safe, but people do not always obey(遵守) the rules. They are careless. If everybody obeys the rules, the roads will be much safer. How can we make the roads safer?Remember this rule. In Great Britain, traffic keeps to the left. Cars, buses and bikes must all keep to the left side of the road. In most other countries, traffic keeps to the right.Before crossing the road, stop and look both sides. Look right and left. Then, if you are sure that the road is clear, it is safe to cross the road. If you see small children or old people, help them to cross the road. We must teach small children to cross the road safely. We must always set them a good example. Small children must not play in the street.根据上文内容判断正(T)误(F)。

答案解析1.【解析】选C 。
本题考查了杠杆的使用。
使用定滑轮既不省距离也不省力，故A 错误；使用斜面省力但费距离，故B 错误；C 图是费力杠杆，动力臂要小于阻力臂的一半，虽然费了力，但省了距离，故C 正确；动滑轮能省一半的力，但费一倍的距离，故D 错误。
2.【解析】选B 。
本题考查杠杆平衡条件的应用。
杠杆平衡条件是动力×动力臂=阻力×阻力臂。
当弹簧测力计逐渐向右倾斜时，拉力（动力）的力臂变小，而阻力、阻力臂不变，欲使杠杆保持平衡，需增大拉力（动力），故选B 。
3.【解析】选C 。
由题图知，钓鱼竿在使用时动力臂小于阻力臂，故为费力杠杆，但省距离，故A 、B 均错；根据杠杆平衡条件F 1l 1=F 2l 2，得2211F 15 N 2 m F 75 N 0.4 m⨯===，l l 故C 正确，D 错。
4.【解析】选B 。
根据题意，必须选择一个可以省力的杠杆才行。
杠杆的动力臂大于阻力臂时，可以实现省力的目的，A 对；动滑轮的动力臂相当于它的直径，阻力臂相当于它的半径。
虽然动力臂大于阻力臂，可以实现省力的目的，但只能省一半力，无法实现用20 N 的力提起50 N 的物体，B 错;斜面相当于一个省力杠杆，C 对；轮轴的动力作用线相当于圆的切线，动力臂相当于圆的半径，阻力臂远小于动力臂，D 对。
5.【解析】选D 。
本题主要考查定滑轮和动滑轮的判断及其特点。
首先判断出滑轮是定滑轮还是动滑轮，然后再根据定滑轮和动滑轮的特点判断省力情况。
甲图中的滑轮，轴固定不动，是定滑轮，定滑轮不能省力；乙图中的滑轮，轴随物体一起运动，是动滑轮，动滑轮能省力。
故选D 。
6.【解析】选B 。
（1）分析甲图可知，n=3，则s=3h ，因为摩擦力可以忽略不计，所以11F G G 3=+动（），111W Gh G W Gh G h G G η===++有总动动； （2）分析乙图可知，n=2，则s=2h ，因为摩擦力可以忽略不计，所以21F G G 2=+动（）， 222W Gh G W Gh G h G G η===++有总动动； 由此可知：F 1<F 2，η1=η2，所以甲图省力，机械效率一样大。
故选B 。
7.【解析】选D 。
钩码的质量是200 g ，重力G=mg=200×10-3 kg ×9.8 N/kg=1.96 N ；滑轮组有3段绳子拉动钩码，在理想状况下，绳子末端的拉力即弹簧测力计的示数11F G 1.96 N 0.65 N n 3==⨯=；若考虑到动滑轮重、绳子重和摩擦，绳子末端的拉力就大于0.65 N 。
故选D 。
8.【解析】选A 。
本题考查利用滑轮组做功和机械效率的有关计算。
由题可知F=80 N,G=120 N,h=1 m,s=2 m 。
则W 有=Gh=120 N ×1 m=120 J,动滑轮的重力G 动=2F-G=2×80 N-120 N=40 N,利用滑轮组所做的总功为W 总=Fs=80 N ×2 m=160 J,该滑轮组的机械效率W 120 J 75%W 160 Jη===有总，选项A 说法错误。
9.【解析】本题考查杠杆的平衡条件。
根据杠杆平衡条件可知，G A L A =G B L B ,即m A gL A =m B gL B ,n A m 0gL A =n B m 0gL B ,则B A B A L 2n n 32L 3==⨯=。
答案：210.【解析】船桨的上端为支点，上端到下面手的距离为动力臂，船桨的上端到末端为阻力臂。
显然动力臂小于阻力臂，是费力杠杆，但是可以省距离。
答案：费力 省距离11.【解析】F 由两段绳子承担,每段绳子的拉力F 200 N F 100 N 22===绳。
物体A 匀速前进,其摩擦力跟每段绳子的拉力相等,为100 N 。
答案：动 10012.【解析】盘山公路相当于简单机械中的斜面，使用它可以省力。
答案：斜面 省力13.【解析】物体A 的重力G=mg=50 kg ×10 N/kg=500 N绕过动滑轮的绳子股数n=2，绳子自由端移动的距离s 绳=2×0.5 m=1 m ，拉力F 做的功W=Fs 绳=120 N ×1 m=120 J 拉力做功的功率W 120 J P 12 W t 10 s=== 答案：500 1214.【解析】两名运动员从高处落下时做的功W 总=2Gh=2mgh=2×60 kg ×10 N/kg ×1.5 m=1 800 J质量为50 kg 的运动员被弹起时做的功W有=G′h′=m′gh′=50 kg×10 N/kg×3 m=1 500 J 此过程中做的额外功W额=W总-W有=1 800 J-1 500 J=300 J跳板的机械效率W 1 500 J83.3%W 1 800 Jη===有总答案：300 83.3%15.【解析】本题考查力臂的画法。
