通俗點(diǎn)說,介詞就是一種連接詞,語法功能是后接名詞結(jié)構(gòu).英語里一共就怎么幾個(gè)介詞：
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
謂語就是對(duì)主語的稱述或說明,只能由動(dòng)詞結(jié)構(gòu)擔(dān)當(dāng),且一句話只能由一個(gè)謂語.
比如這句話：Prepositions are short words (on, in, to) that usually stand in front of nouns (sometimes also in front of gerund verbs).
謂語只有一個(gè)就是are,that后面是從句,in of 就是介詞
找本語法書看看就好了
