你的朋友：李华18、自然 Nature范文Hello, everyone,I'm honored to show you around Dujiangyan tomorrow. To help you have a knowledge of it, I'd like to make a brief introduction to it.Dujiangyan, with a long history of over 2000 years, is an ancient irrigation system situated in the Chengdu Plain, Sichuan Province. Once the plain was often flooded by the Min River which rushed down from the Min mountains. Therefore, Li Bing, one of the governors for the state of Qin, together with his son, headed the construction of the irrigation system, Dujiangyan. It not only acts as a way to prevent flood and irrigate the cropsbut also a kind of transportation. Now it's listed as a World Heritage Site as well as a AAAAA tourist attraction. Meanwhile, it's the oldest irrigation system in the world that is still in use today.I bet that your visiting it in person will leave you a wonderful impression.Yours,Li Hua 参考译文：大家好,我很荣幸明天带你们参观都江堰。
为了帮助你们了解它，我想在这里做一个简单的介绍。
都江堰位于四川省成都市平原，是一个有着 2000 多年悠久历史的古老灌溉系统。
从前，平原经常被从岷山奔流而下的岷江淹没。
因此，秦国的一位官员李冰和他的儿子主持了都江堰灌溉系统的建设。
它不仅是一种防止洪水和灌溉农作物的方法，也是一种交通工具。
现在它被列为世界文化遗产和 AAAAA 级旅游景点。
同时，它是世界上至今仍在使用的最古老的灌溉系统。
我相信你们参观后，一定会有个美好的印象。

Take our school for example.Now there are several HD-cameras monitoring the whole campus in case of emergency or school bullying. At meal time, we can watch TV news in the dinning hall, learning the latest international and domestic events. Not only can our teachers use multimedia equipment to make their classes more lively, but also they can mark papers on the computer, which greatly improves the efficiency of paper-scoring. Additionally, we can do many things conveniently, such as paying by Alipay, getting food by card, going to school by shared bike and so on.In a word, it is the development of science and technology that makes such a comfortable and convenient life available to us.参考译文科学技术影响生活正如我们所看到的，科学技术已经深深地影响了我们的生活。
以我们学校为例：现在有几个 HD-camera 监控整个校园，以防发生紧急情况或校园欺凌事件。
吃饭的时候，我们可以在餐厅里看电视新闻，学习最新的国际和国内事件。
我们的老师不仅可以使用多媒体设备让课堂更生动，而且可以在电脑上批改作业，这也大大提高了工作效率。
此外，我们做事情也变得方便，如支付宝支付、用校园卡购买食物、骑自行车上学等等。
总而言之，正是科技的发展使我们能够拥有如此舒适、方便的生活。
