as possible是虛詞|as soon

不是

as soon as possible意思：儘快，as soon as +形容詞adj 表示像……一樣快的

而虛詞是沒有實際意義的詞，虛詞包括介詞、連詞、冠詞、感歎詞等四類

as ... as possible，當然是比較結構。第一個 as 是參與比較的程度副詞，第二個 as 是比較連詞，引導（省略成分的）比較從句。

I will come as soon as possible. 我儘可能早來這裏。

在 possible 之前省略了 it is，一般是不需要添加的。

如:

I will come as soon as it is possible.

在 it is possible 中，it 指你來這件事，這個情況。it is possible 還可以用 I can 表示：I will come as soon as I can.

舉一反三，以此類推：

You must make the houses as strong as possible. 你應該把房屋建得儘可能結實。

I'd like to see you as early as possible. 我想要儘早見你。

I want to clear my debts as quickly as possible. 我想把我的債務儘快還清。
