簡(jiǎn)單區(qū)分,about通俗大眾；on學(xué)術(shù)【專業(yè)】性強(qiáng)
on與about 二者都是介詞,意為“關(guān)于,論及”等,一般情況下,二者可以互相替換,但二者有點(diǎn)區(qū)別：about常用于簡(jiǎn)單的或淺顯的論述等,是一般用語(yǔ),多用于講故事,談話；思考等；
on多用于系統(tǒng)論述或?qū)ｎ}講演、論著等,具有學(xué)術(shù)性,如：The teacher told us a story about Lei Feng.It's very moving.He will give us a talk on the history of the Party.他將給我們做個(gè)關(guān)于黨史的報(bào)告.
正誤例析 今天下午我們將聽一個(gè)關(guān)于非洲歷史的演講.
誤：We're going to listen to a lecture about African history his afternoon.
正：We're going to listen to a lecture on African history this afternoon.
析：介詞about和on都可以作“關(guān)于”解.on表示一本書、文章或演講是嚴(yán)肅的、學(xué)術(shù)性的,可供專門研究這一問題的人們參考；about則表示其內(nèi)容比較通俗,一般人都可閱讀.
