自然能源英文

同学们，在遥远的明朝，没有电和蒸汽来发动船只，郑和是怎么样完成下西洋的壮举呢？这是因为他们借用了一种自然能源——风。很早以前，人类就学会了利用风能来改善我们的生活。风在自然界里做了许多工作。它能使大范围的热量和水汽混合、均衡，调节空气的温度和湿度；能把云雨送到遥远的地方，使地球上的水分循环得以完成。风在日常生活中的作用很多，帆船的行驶也是靠风力的推动。郑和下西洋就是多亏了风的帮忙才能得以成功。Dear classmates, in the long-past Ming Dynasty, under the condition that there was no electricity nor steam to motivate boats, how could He ZHENG completed the feat of exploring the oceanic countries? It is because of a natural energy- wind, that they utilized to succeed. Long long ago, mankind had mastered the ways to use winds to improve their lives. Wind does a lot of work in the nature. It can mix and balance heat and vapor on a large scale and modulate the air temperature and humidity as well as complete the water cycle on the earth by sending clouds and rain to faraway places. Wind plays many roles in our daily lives, for example,the moving of a yacht is realized by the force from the wind blowing the sails . Mr. Zheng succeeded in his oceanic adventure because of the help from Aeolus. 空气在水平方向上的流动就叫做风。风的形成是空气流动的结果。是气压在水平方向分布的不均匀。简单地说，风是空气分子的运动。风能的形成主要是将空气分子运动时所具有的动能转化为其他形式的能。帆船就是通过船帆兜风受到推力来前进的。随着风向的变化，船员们及时的调整帆的角度，以此得到前进方向的推力。Wind is the flow of air in a horizontal way. The formation of wind is the result of the air movement and the uneven distribution of air pressure in the horizontal direction. Simply speaking, wind is the movement of air molecules. The wind energy is formed mainly by changing the kinetic energy from air molecule movements into other forms of energies. The movement of a sailing boat is achieved by the energy from the wind blowing the sails. With the changes of wind directions, sailors can adjust the angles of sails in time to get the thrust for forward movement. 在这个实验中，在风扇的转动下，空气分子运动起来，形成了风，风作用于船帆，小船得到了前进的推力，所以能够前进。In the experiment, due to the rotation of the fan, air molecules start moving to form wind, which works on the sails to provide the energy to push the boat. That is the reason why the boat can move forward. 仅供参考，欢迎指正
