如何写旅游景点类描述性说明文
描写性说明文写作要特别注意知识的科学性、准确性和行文的条理性。
旅游景点类说明文介绍旅游景点时，要对旅游地的位置、历史和景点等进行简要介绍；也可介绍别人对旅游地和景点的评价。
【写作步骤】
第一步：
整体介绍旅游地，可以包括其基本地理信息、历史人文特色或旅游的重要性和必要性等。
第二步：
具体介绍地方特色，可以从风景、人文等方面入手，突出特色，把握重点。
第三步：
指导游客衣食住行等方面的信息，并充分考虑游客的需要。
时态常用一般现在时态，人称常常用第三人称。
在写作过程中，作者可以按空间顺序，由远及近，由上及下，由外及里，由前到后组织材料，也可以按视线转移的顺序组织材料。
【常用句式】
①Abelocatedin/liein/totheeastofB
②coveranareaof...
