一、副詞 soon 作“久”、“早”講
1.We shall soon know the result. 我們不久（即將）知道結(jié)果。
【注】有時(shí)soon和fast譯成漢語(yǔ)時(shí)都表示“快”，但前者指時(shí)間的遲早中的早，后者指動(dòng)作快慢中的快。例如：
2.You will soon go to the factory. 你們很快要下廠了。(指時(shí)間的早)
3.Speak to me as fast as you can. 你對(duì)我說(shuō)話能多快就多快。（指說(shuō)話速度的快）
二、\”No sooner…Than\”一般用于敘述過(guò)去事情，表示“一······就······”的意思。如果表示否定的短語(yǔ) no sooner 位于句首，那么后面主語(yǔ)、謂語(yǔ)就顛倒
No sooner had the words been spoken than he realized that he should have remained silent。話一出口，他便意識(shí)到他本該保持沉默。
【注】than后面的狀語(yǔ)從句，常用過(guò)去時(shí)。主句動(dòng)作一般發(fā)生在從句之前，只是否定式而已，故用過(guò)去完成時(shí)。
三、“as soon as”引導(dǎo)的是時(shí)間從句，作“一······就······”講
1.As soon as ? saw him, I told him what we needed. 我一見(jiàn)他，就告訴了他，我們需要什么。
2. I will let you fly to Shanghai as soon as we complete the work. 我們把這項(xiàng)工作一做完，我就讓你飛往上海。
【注1】主句的動(dòng)作是在時(shí)間狀語(yǔ)從句的動(dòng)作之后發(fā)生的，但主句和從句常用一般過(guò)去時(shí)。上面第2句由于用來(lái)敘述將來(lái)的動(dòng)作，故主句用將來(lái)時(shí)，而時(shí)間狀語(yǔ)從句像往常一樣，只能用現(xiàn)在時(shí)代替實(shí)際上的將來(lái)時(shí)。由于從句動(dòng)作畢竟是在主句動(dòng)作之前發(fā)生，偶爾也有使用過(guò)去完成時(shí)的情況。例如：
As soon as she discovered her errors, she made the necessary corrections to her data. (那時(shí))她一發(fā)現(xiàn)有錯(cuò)，就對(duì)自己的數(shù)據(jù)作必要的修改。
四、注意都表示“一······就······”的幾個(gè)同義句的表達(dá)式
She sent an E-mail as soon as she received a letter from you. 她一收到你的來(lái)信就發(fā)了一封電子郵件。
同義的句子如下：
She had no sooner received a letter from you than she sent an Email.=She had scarcely (或 hardly) received a letter from you when (或 before) she sent an Email.
五、注意“主語(yǔ) would(或had) as soon …… as 被棄事物或動(dòng)作”這種句型，它表示“寧愿······而不······”之意
He would (或 had) as soon you took a glass of tea as a glass of milk. 他希望你與其喝一杯牛奶，還不如喝一杯茶。
【注】這里用 would 或 had 表示虛擬語(yǔ)氣。
六、注意“主語(yǔ) would sooner 原形動(dòng)詞 than 原形動(dòng)詞”這種句型，它表示“寧愿早點(diǎn)······而不愿······”之意
Wouldn\’t you sooner take this medicine than be sick? 你寧可不吃藥而甘愿生病嗎?(這里用 would 表示虛擬語(yǔ)氣。)
