介绍梨的优点英语作文【三】
梨是一种外形漂亮的水果，梨的表面是很光滑但绝对不是很粗糙，仔细摸一摸有很多颗粒形状的东西。梨的外形是一个圆的、黄黄的身子，像一个穿着黄色衣服的小姑娘，小巧可爱很讨人喜欢！梨的里面有香甜可口的汁，闻一闻会散发出迷人的香气，如果你在梨的身上咬上一口脆脆的、甜甜的真是香甜无比，而梨却哭了，流下了香甜可口的汁，梨的大小和成人的拳头一样，小的跟小孩子的拳头那么大。
梨的种类很多，比如：鸭梨、苹果梨、大头梨、香梨、水梨等，梨的种类有一百多种呢！
梨的营养价值非常高，含有钙、铁、维生素等物质，梨的作用也非常多，可以止痰、润喉这些作用，对气管炎患者尤其有益。传统中医理论认为，梨可入药，梨可以高压，心脏病、便秘头昏、失眠、多梦等病症有良好的辅助治疗作用。
梨有许多产地最著名的还是河北，梨已经有4000多年的历史，被誉为“天然矿泉水”。
梨的贮存方法有很多，如果在仓库里贮存的梨就要多通风，库内二氧化碳要2%时就会引起果心和果肉褐变。因此要在贮藏的前期和后期每天通风换气1—2小时，中期2—3天换气一次，每次1—2小时保鲜袋可有效吸收2烯气体，防止梨腐烂。
