1、介词英语中称为“preposition”是由“前缀pre-（在前部）+position（位置）”构成的，所以又叫前置词。一般放在名词、代词或动名词的前面。介词是虚词，主要用来表示人、物、事件等与其他人、物、事件之间的关系,如空间位置、时间先后、因果关系、方式方法等。介词与其宾语构成介词短语。可作介词宾语的主要有名词、代词、动名词（或动名词短语）、名词性从句等。在英语里，它的搭配能力最强。但它不能单独作句子成分，需和名词或代词(或相当于名词的其他词类、短语及从句)构成介词短语，才能在句中充当成分。解题技巧： 1. 要认真掌握好常用介词的主要用法及动词与介词的搭配。这是考查的重点，也是做题的基础。
