根本不知道什么叫介词 什么叫谓语 能告诉我什么叫介词 什么谓

通俗点说,介词就是一种连接词,语法功能是后接名词结构.英语里一共就怎么几个介词：
1. in2.on3.under4.behind5.at 6.of7.after 8.between 9.off10.to 11.with 12.around
13.as14.by 15.over 16.below 17.about18.without 19.above20.before 21.into 22.onto 23.like 24.unlike 25.for26.beneath 27.from 28.among29.along30.within 31.during32.beside 33.plus ; minus; times
谓语就是对主语的称述或说明,只能由动词结构担当,且一句话只能由一个谓语.
比如这句话：Prepositions are short words (on, in, to) that usually stand in front of nouns (sometimes also in front of gerund verbs).
谓语只有一个就是are,that后面是从句,in of 就是介词
找本语法书看看就好了
