将下列短文翻译为中文
Unit 4
11 The second running skill is endurance. An athlete needs good endurance to
be able to run for a long time without getting tired. This is a very important skill
in most sports.
12 The key to endurance running is to conserve energy. This means using as
little energy as needed to move oneself forward. As with sprinting, there is a
technique runners use to help them become better endurance runners. This
technique is known as the gravity pull technique. Here’s how it works:
13 First, the athlete leans forward just enough so that he has to keep
stepping forward to keep from falling. Second, he swings his arms long, to keep
his balance. Finally — and here’s the tricky part — he stays in that position for
the entire course of the run!
14 It takes quite a bit of practice to become skilled at this technique. However,
by running this way, the athlete uses the pull of gravity to move forward, rather
than having to use his own energy to push himself forward. Isn’t that clever?

11日第二次运行技能是耐力。一名运动员需要良好的耐力
能够运行了很长一段时间没有得到厌倦。这是一个非常重要的技能
在大多数体育运动。
12耐力跑的关键是节约能源。这意味着作为
小能源需要将自己前进。正如短跑，有
运动员使用的技术，帮助他们成为更好的耐力运动员。这个
技术被称为引力拉技术。其工作原理如下：
13首先，运动员倾斜着足以使他保持
挺身而出继续下跌。第二，他摆动他的手臂长，保持
他的平衡。最后-这是棘手的部分-他留在这个位置的
整个过程中运行！
14需要相当多的实践，成为熟练的技术在此。但是，
通过运行这样，运动员使用的重心拉向前进，而不是
不必用他自己的能量，推动自己前进。难道这不是聪明的？
