现在我真的很沉迷机械装置，但是你可以想象重物掉落的时候会带动桨轮旋转。
Now I'm really fantastic at drawing this mechanical device, but you can imagine that dropping weight can cause a paddlewheel to turn.
这是一个很简单的问题，通过观察重量是多少以及它下降了多远，来确定桨轮做了多少功。
It's a trivial matter, by looking at what is the weight and how far does it drop, to say OK, how much work is done by the paddlewheel.
它的两舷装着会转动的桨轮。
好，让我们看看重物的质量,以及它下落的距离，就知道桨轮做了多少功。
So, it's a trivial matter, by looking at what is the weight and how far does it drop, to say OK, how much work is done by the paddle wheel.

桨轮船把桨楫改为桨轮推进，把桨楫的间歇推进改为桨轮的回旋推进(连续运转)。
Oar oar oar ships to change paddle wheel forward, the oar oar paddle wheel instead of the intermittent advance of the roundabout forward (continuous operation).
那接下来可以做一件类似的事，但不再是蜡烛，我们将它换成一个桨轮，桨轮末端拴一个重物，它可以从这掉落到这。
Now you could do a similar sort of thing, but instead of having a candle, you have a paddle wheel, and the paddle wheel is spun by a weight that's dropping from here to here.
另外中国也是世界上二氧化硫排放最多的国家，由此产生的酸雨正在侵蚀韩国和日本的森林面积，甚至日本渔民也受到了中国环境污染问题引起的影响：大型海蜇在漂游到日本北部之前会先在中国沿海产卵，这破坏了大麻哈鱼和黄鱼的捕捉，渔网和轮桨也因此受损。
The country is also the world's biggest emitter of sulphur dioxide. The resulting acid rain is damaging Korean and Japanese forests.
为了头轮能更加工作，桨必须起作用。
For the great wheel to work once more, the paddles must function.
