硒 对人体的好处
硒对人体的主要作用有以下表现：1、抗氧化、抗衰老。
人体内的氧化损伤，会引起人的生病、衰老。
而硒可以激活人体自身的抗氧化系统，控制沉降的氧化损伤，预防疾病的发生。
硒的抗氧化作用，是维生素E的五百倍以上。
2、保护和修复细胞。
硒在体内的细胞质中的抗氧化物，具有代谢活性，保护细胞的接触结构，减少氧化损伤。
保护细胞，进而保护人体心脏、肝、肾、肺、眼等重要器官。
3、提高红细胞携氧能力。
硒可以保护红细胞，防止红细胞中血红蛋白被氧化，使携氧能力增强，能给机体的每一细胞带来足够的氧气，使每一个细胞都能维持正常的功能。
4、增强人体免疫力。
硒能增强免疫系统，并能够认识到身体的病变。
还可以提高机体的免疫功能，从根本上提高了抗病能力，这是硒可适性疾病的主要原因。
5、解毒、排毒。
硒作为带负电荷的非金属离子，在人体内可以结合带正电荷的有害金属离子，彻底消除有毒的金属离子，达到解毒和排毒的效果。
6、癌性肿瘤的预防。
微量元素硒既能抑制多种潜在的致癌物质，还能成为癌细胞的杀伤剂，可降低化疗的副作用，减轻晚期癌症患者的疼痛。
体每天必须摄入50--250毫克硒。
可直接补充硒营养补充品，补充每日所需。

关于龙井茶的英语作文
Longjing Tea, West Lake Dragon Well TeaAs a type of green tea gaining a great reputation all over the world, Longjing tea grows near West Lake, Hangzhou of Zhejiang Province, and is characterized by its green color, delicate aroma, mellow taste and beautiful shape.With a long history of over 1,200 years, Longjing tea was named after the Dragon Well in Longjing Village which lies at the north-west foot of Wengjiashan Mountain in the west part of West Lake. Thanks to Emperor Qianlong of the Qing Dynasty , Shifeng Longjing tea has earned a high reputation. The legend went that the Emperor Qianlong visited Lion Peak Mountain during his Hangzhou travels, and he saw some ladies picking the tea at the foot of the mountain. He was so interested in their movements that he decided to have a go himself. While picking the tea, he received the news of his mother’s illness, so he carelessly put the leaves in his right sleeve and left Hangzhou for Beijing. He visited his mother immediately upon his arrival in Beijing, and Empress Dowager smelt the fragrance of the leaves from his sleeves and wanted to have a taste. Emperor Qianlong ordered it to be brewed for her, and she found herself completely refreshed after drinking a cup of tea, and she even praised it as a remedy for all ills. From then on, Shifeng Longjing tea was listed as the tribute tea especially for Empress Dowager.Both the picking and making processes of Longjing tea are elaborate in order to make sure it retains its high quality and original flavor, according to which Longjing tea is classified into six grades . Much importance is emphasized on the timeliness of the leaves being picked, and the tea leaves which are picked before the Qingming Festival or after the Grain Rain Period are considered to be the top grade, while the ones picked before the Grain Rain Period or after the Qingming Festival are considered worthless.Longjing tea is a delicious beverage with potential health benefits owing to its rich antioxidants; however, it’s also rich in caffeine which could deleteriously affect some tea drinkers.
领导讲话稿：市委书记在市发改委调研座谈会上的讲话
领导讲话稿：市委书记在市发改委调研座谈会上的讲话今天到市发改委调研，主要是看望大家，感谢大家长时间在同一个部门、同一个岗位上的辛勤工作、默默付出。
这些年，我市的经济社会发展情况，按照经度思维方式，自己跟自己比有很大进步，但是按照纬度思维方式，与周边发展好的地方相比，还有这样或那样的差距。
这是我最朴素的认识，也是我的理性判断。
实事求是地讲，相比我们拥有的区位优势、交通优势、土地资源、人才优势，我市的发展还没有释放应该释放的能量，没有激发应该激发的活力。
原因在哪里
还是差在发展战略谋划不足、重大项目落地不够、奋发有为的精神状态不佳。
刚才，发改、经信、农办等部门分别从项目方面，汇报了去年的工作情况、今年的工作打算，包括存在的问题和相关建议。
总体感觉，计划可观令人振奋，但能否实现令人忐忑。
比如，今年计划安排的570亿元固定资产投资，能不能扎扎实实地完成
特别是230亿元的工业投资，能否完成还要打问号。
政府主导的基础设施建设项目没有问题，但工业投资，受外部环境、企业后续资金、企业家信心等多重因素影响，我们不能控制，所以没有把握。
农业项目也受大气候影响，比如民间投资到底能不能进一步激活
这是听了情况后我的基本感受。
关于下一步项目怎么抓，工作怎么推进，我想从宏观角度讲四点意见。
各地各部门都要按照这四个维度的城市定位，超前谋划一批能够从根本上改变发展格局的支撑性项目。
农业板块要谋划打造荆楚富硒粮仓、中国
