今天我们学习高考英语语法填空——介词。通常情况下，无括号提示词。介词之后通常跟名词、代词、动名词或词组，构成介宾短语。
1.固定搭配。例如，
a)Duo to the growing popularity of environmentally-related and adventure travel, various types of trips are now being classified as ecotourism.（此处为固定结构,“各种各样的”various of…故填of.）[2021年全国乙卷]
b)Bamboo plants are associated with health, abundance and a happy home.（翻译为：竹子与健康，富足和幸福的家庭联系在一起，此处与前面的are associated连用表示“与……相关联的”，故填with.）[2020年全国2卷]
2.根据具体语境填空。例如，
It was built originally to protect the city in the Tang dynasty and has now been completely restored.（ 此处翻译为“在唐朝”与the Tang dynasty构成介词短语。[2021年全国甲卷]
