新概念一共144課，其中單課為課文，雙課為語(yǔ)法和練習(xí)。整本書是以單數(shù)課為正課，并附帶有插圖而雙數(shù)課則是針對(duì)單數(shù)課所講的內(nèi)容有針對(duì)性地進(jìn)行練習(xí)，展現(xiàn)出整個(gè)新概念一教材區(qū)別于其他教材的獨(dú)特之處。為您整理了以下內(nèi)容，僅供參考。希望可以幫助到您！如果您想要了解更多相關(guān)內(nèi)容，歡迎關(guān)注！
1、directly/immediately+從句
該句型相對(duì)少見一些。其中的directly和immediately都用作了連詞。如：
We'll come directly we have finished the work. (我們工作一結(jié)束就過(guò)來(lái)。)
I came immediately I heard the news. (我一聽到這個(gè)消息,馬上就來(lái)了。)
2、directly引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)，可以放在主句前面或者主句后面。例如：Directly the teacher came in everyone was quiet . / He came directly I called .
3、on doing
介詞on后接動(dòng)名詞，也可以表示“一...就...”。如：
On arriving home I discovered they had gone. (我一到家就發(fā)現(xiàn)他們已經(jīng)離開了。)
