soon是什么意思？一、副词 soon 作“久”、“早”讲

1.We shall soon know the result. 我们不久（即将）知道结果。

【注】有时soon和fast译成汉语时都表示“快”，但前者指时间的迟早中的早，后者指动作快慢中的快。例如：

2.You will soon go to the factory. 你们很快要下厂了。(指时间的早)

3.Speak to me as fast as you can. 你对我说话能多快就多快。（指说话速度的快）

二、"No sooner...Than"一般用于叙述过去事情，表示“一······就······”的意思。如果表示否定的短语 no sooner 位于句首，那么后面主语、谓语就颠倒

No sooner had the words been spoken than he realized that he should have remained silent。话一出口，他便意识到他本该保持沉默。

【注】than后面的状语从句，常用过去时。主句动作一般发生在从句之前，只是否定式而已，故用过去完成时。

三、“as soon as”引导的是时间从句，作“一······就······”讲

1.As soon as ı saw him, I told him what we needed. 我一见他，就告诉了他，我们需要什么。

2. I will let you fly to Shanghai as soon as we complete the work. 我们把这项工作一做完，我就让你飞往上海。

【注1】主句的动作是在时间状语从句的动作之后发生的，但主句和从句常用一般过去时。上面第2句由于用来叙述将来的动作，故主句用将来时，而时间状语从句像往常一样，只能用现在时代替实际上的将来时。由于从句动作毕竟是在主句动作之前发生，偶尔也有使用过去完成时的情况。例如：

As soon as she discovered her errors, she made the necessary corrections to her data. (那时)她一发现有错，就对自己的数据作必要的修改。

四、注意都表示“一······就······”的几个同义句的表达式

She sent an E-mail as soon as she received a letter from you. 她一收到你的来信就发了一封电子邮件。

同义的句子如下：

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“主语+would(或had)+as soon+……+as+被弃事物或动作”这种句型，它表示“宁愿······而不······”之意

He would (或 had) as soon you took a glass of tea as a glass of milk. 他希望你与其喝一杯牛奶，还不如喝一杯茶。

【注】这里用 would 或 had 表示虚拟语气。

六、注意“主语+would+sooner+原形动词+than+原形动词”这种句型，它表示“宁愿早点······而不愿······”之意

Wouldn't you sooner take this medicine than be sick? 你宁可不吃药而甘愿生病吗?(这里用 would 表示虚拟语气。)
