(一)介词在英语用词里也属于难缠的一个项目。因为它涉及方面很广，而且变化多端，往往令人捉摸不定，记起来很麻烦。因此就有有心人弄了一个《介词口诀》来帮助学习者；也有人写了《PrepositionSong》令学习者一面唱歌一面轻松地记忆介词的用法。介词英文叫作Preposition(简称prep)，它由pre和position组成，pre是前面的意思，而position是位置的意思。因此以前中文译作“前置词”，就是一种放在名词(或相当于名词的词语)前面的虚词。
一、常用的介词about,above,across,after,against,around,at,before,behind,below,beneath,beside,besides,between,beyond,by,down,during,except,for,from,in,inside,into,like,near,of,off,on,out,outside,over,since,through,throughout,till,to,toward,under,until,up,upon,with,without,accordingto,becauseof,bywayof,inadditionto,infrontof,inplaceof,inregardto,inspiteof,insteadof,onaccountof,outof.
哇，这么一大堆！别怕别怕，大部份的介词都不难理解，比较令人头痛的只是下列几个：at,by,to,in,for,of,on,from,with其中又以at,by,in,on为四大“要犯"！学习介词就是要抓住这几"要犯"，看招吧，嘿嘿!!

怎样？唱完十段歌词，你就学到许多介词用法喽。其中包括四大“要犯”at,by,in,on。另外再加上许多虫虫蚁蚁，有的还得劳驾找一找喔，呵呵。大家多唱几遍，下回我们再见时，你就更加胸有成“介”了，哈哈。
