92 years ago, in the Los Angeles Olympics, a man who looked a bit tired stood on the start line of the men's 100 metres. He had just spent 21 days getting here from China. This was the first time that a Chinese athlete participated the Olympics. Maybe it's a common thing for many other countries, but for a country that was struggling with wars, everything was not that easy. He was the hero of China at the moment he standing on the track. Though he didn't get a good score due to the long trip, he had alreay represented the Olympic spirits. He was respected after returning home from generation to generation. His name is Liu Changchun .He died in 1982, which was also the year that a great Chinese athlete was born,his name is Liu Xiang. They have the same family name. Two years later, in the 1984 Los Angeles Olympics, our athlete won the first gold medal. The same place, Chinese atheletes eventually prove themselves. The great Olypics spirits encourage each person who is just suffering from tough time to stand up and to be better. Never give up, just do it!

I can't describe these pictures in English clearly. Please help me. 今年6月,当我参观北京圆明园时,我看到一些图片,介绍圆明园中喷泉的工作原理,我当时震惊了,中国的古代没有电,没有水泵,怎样实现喷泉? 谁能想象如此漂亮的喷泉,如此漂亮的建筑,里面竟然藏着一个人牵着一头驴在绕着柱子做圆周运动。一楼的齿轮与二楼的柱子同轴旋转,通过一对锥齿轮,将二楼的旋转运动转化为一楼相互垂直的旋转运动,带动了一楼曲柄旋转。曲柄旋转时,通过曲柄上的连杆带动活塞在气缸内上下往复运动,将一楼水池的水源源不断地抽吸入活塞,再压入二楼水池。再通过不同粗细的管子将二楼水池的水放出来,行成喷泉。不得不赞叹设计师的智慧。 On April this year, when I visited the Old Summer Palace in Beijing, I saw some pictures that introduced how the fountain working in Old Summer Palace. I was shocked. There were not electricity and pump, How to make a fountain? Who can imagine what a beautiful building and fountain, a donkey followed a person hiding in the seconditions floor made the beautiful fountain. What intelligent designers!

90 day's training: Day 12 Could you please check my sentences? Thanks in advance. 🐰 1) This picture was taken on the Herren Island. This castle is called the Herrenchiemsee Castle. It was built by the king Ludwig Ⅱ of Bavaria in Germany. 2) He is known for the world wide famous castle Neuschwanstein. The Herrenchiemsee Castle is one of his three castles. 3) This castle is modelled the Versailles in France, but the size is much smaller than the Versailles. 4) There was the carriage which we rode in. These horses were very cute so I asked a coachman if it was no problem to take their pictures. 5) He said me that I should take pictures from left side. He told me that it would be better to take the pictures of horses because of the beautiful background with the castle.
