conj.(連詞)

once用作連詞時(shí)可引導(dǎo)時(shí)間狀語從句和條件狀語從句。用于前者時(shí)意為“一旦…就…”,所引導(dǎo)的從句多很短; 用于后者時(shí)意為“只要”,這種條件從句似帶有時(shí)間條件的含意。

once引導(dǎo)的從句中有些部分可以省略。

n.(名詞)

at once, directly, immediately, instantly, presently, right away

這組詞(組)的共同意思是“立即”“馬上”。其區(qū)別在于:

1.at once主要指動(dòng)作迅速,但中間多有一段距離,且at once比immediately意味更強(qiáng)。例如:

I'm leaving for Rome at once.我馬上去羅馬。

He gave orders for the work to be started at once.他下令立即開始那項(xiàng)工作。

2.immediately側(cè)重指時(shí)間“緊接著”。例如:

I came immediately after I'd eaten.吃過飯我立即就來了。

Please close your books immediately and answer these questions.請(qǐng)立即合上書,回答這些問題。

I left immediately when the clock struck twelve.鐘剛打12點(diǎn)我就離去了。

3.right away經(jīng)常出現(xiàn)在美式英語中。例如:

I'll do it right away.我立即去辦。

He had written down a list of things to do right away.他已寫下須立即做的事情。

Don't expect them to approve of the design right away.不能期望他們馬上批準(zhǔn)這項(xiàng)設(shè)計(jì)。

4.instantly也是指動(dòng)作迅速,但它更強(qiáng)調(diào)的是同時(shí)發(fā)生,中間有很短的距離或無距離。例如:

The electrician went instantly in answer to the phone call.電工師傅一接到電話馬上就去了。

He was killed instantly in a car accident.在車禍中,他當(dāng)場(chǎng)死亡。

5.directly強(qiáng)調(diào)“直接地”,多與“迂回繞過”相對(duì)。例如:

Whether he sailed directly across the bay or coasted round it is uncertain.他是徑直駛過海灣,還是沿海岸迂回繞過的,現(xiàn)在還無法確知。

6.presently強(qiáng)調(diào)過一會(huì)再去做某事。例如:

I will do the dishes presently, but I want to finish the story first.我過一會(huì)去洗碟子,不過我想得先看完這篇故事。
