"Notas you represent it. Had she merely dined with him, she might only havediscovered whether he had a good appetite; but you must remember that fourevenings have been also spent together -- and four evenings may do a greatdeal."
"Yes;these four evenings have enabled them to ascertain that they both like Vingt-unbetter than Commerce; but with respect to any other leading characteristic, Ido not imagine that much has been unfolded."
"Well,"said Charlotte, "I wish Jane success with all my heart; and if she weremarried to him to-morrow, I should think she had as good a chance of happinessas if she were to be studying his character for a twelvemonth. Happiness inmarriage is entirely a matter of chance. If the dispositions of the parties areever so well known to each other, or ever so similar before-hand, it does notadvance their felicity in the least. They always contrive to grow sufficientlyunlike afterwards to have their share of vexation; and it is better to know aslittle as possible of the defects of the person with whom you are to pass yourlife."
"Youmake me laugh, Charlotte; but it is not sound. You know it is not sound, andthat you would never act in this way yourself."
请教老师：I should think she had as good a chance of happiness as if she were to bestudying his character for a twelvemonth. 这里出现的as...as if 如何剖析和理解句子的意思？
as引导的比较分句或方法状语从句本身可以是个带有if从句的虚拟条件句。因为as从句结构与主句结构相同，一般as从句的主谓结构省略，只保留if 从句，得到as if 引导的方法从句或比较状语从句。比如：
He speaks English as he would speak it if he werean Englishman. as 从句为方法状语从句。本句中he would speak it与主句结构相同，省略后听话人可以从主句结构推知省略了什么，所以一般he would speak it省略，得到下句：
He speaks English as if he were an Englishman. asif引导方法状语从句
He speaks English as fluently as he would speakit if he were an English man. as从句为比较状语从句。同理，一般省略与主句结构相同的he would speak it, 得到下句：
He speaks English as fluently as if he were anEnglishman. as if引导比较状语从句
也就是说，as if 从句本质上是as 从句省略了主谓结构，只保留了从句中的if从句（if为虚拟条件句）。因为as可以引导方法状语从句，也可以引导比较状语从句，所以as if从句除去多用于引导方法状语从句外，也可以用于as... as if... 比较结构。
你的句子中，as if 从句就不是方法状语从句，而是as ... as if 比较结构，特殊之处是，主句本身又是一个虚拟条件句的主句而已。
if she were married to him to-morrow, I shouldthink she had as good a chance of happiness as （he wouldhave) if she were to be studying his character for a twelvemonth.
假如她明天就嫁给他，我想她感到幸福的几率和她研究他的性格特点一年后（再嫁给他）感到幸福的几率相同。（事实上她明天不会嫁给他，事实上她也不会研究他的性格特点一年，所以句子用虚拟语气。）
