星期二，在老师的带领下，我们怀着激动的心情前往水质检测公司参观访问。
On Tuesday, under the guidance of our teacher, we visited the water quality testing company with excitement.
公司环境优美，位于郊外，远离喧嚣的城市。背后是连绵起伏的高山，其间云雾飘渺，触手可及。可我们却无暇细看，因为这不是我们此行的目的。
The company has a beautiful environment, located in the outskirts, far away from the hustle and bustle of the city. Behind is a continuous and undulating mountain, with misty clouds and mist within reach. But we have no time to look closely, because that is not the purpose of our trip.
公司展览馆共有五个展区，最令我印象深刻的便是“饮水思源”。从投影机播放的画面中我们了解到，因为没有先进的技术，古人只能用最原始的推车运送沉重的土、石来建造水库。看到从前的水库，我想到古代劳动人民的智慧很了不起，同时感到他们不怕困难的精神令人敬佩。我想，这也是“饮水思源”的含义吧。
The company exhibition hall has five exhibition areas, and the most impressive one for me is "Remembering the Source of Drinking Water". From the image played by the projector, we learned that without advanced technology, ancient people could only use the most primitive carts to transport heavy soil and stones to build reservoirs. When I see the former reservoir, I think of the remarkable wisdom of the ancient laboring people, and at the same time, I feel that their spirit of fearlessness towards difficulties is admirable. I think this is also the meaning of 'remembering the source when drinking water'.
看完视频后，我们接着观赏展览馆里的壁画。在这里我们看到了最早的水库，看到了各种水井，还看到了水质公司的生产流程。在公司实验室，我们了解了各式各样的仪器的特点和用途，感到收获很大。为了让我们加深印象，老师还演示了显微镜的用法呢。
After watching the video, we continued to admire the murals in the exhibition hall. Here we see the earliest reservoirs, various water wells, and the production process of water quality companies. In the company laboratory, we learned about the characteristics and uses of various instruments and felt that we gained a lot. To deepen our impression, the teacher also demonstrated the use of a microscope.
水是万物之源，没有了它，地球上的万物将不复存在。参观结束后，我一直这样想。
Water is the source of all things, without it, all things on Earth would cease to exist. After the visit, I kept thinking like this.
