John acts as if he were the king. (subjunctive past tense)

John acted as if he had been the king. (subjunctive past perfect tense)

Many grammar books show [as if] more or less = [as though] but according to my late professor (he was the professor of English), they are not the same.

He acts as if he were crazy. = He acts as (he would act) if he were crazy.He acts as though he were crazy. = He acts as (he would NOT act) though he were crazy.Therefore, [as though] is more emphatic than [as if].

I wrote the notes for teaching my students (original note from my late professor, Mr. Kwan Kee Cheong, who passed away 20 years ago). I revised the notes to add adverb clauses and to include a lot of examples from different grammar books, which are no longer available on the market.

the sentence:[Do in Rome] should be (When in Rome, do as the Romans do), which is an idiom.

Adverb Clause of Manner
連接方式副詞從句與主句的詞主要有：
as, as if, as though
例如：
You should pronounce this word as your teacher
pronounces it.
* "as" 意指「一如﹝完全一樣﹞」
* 上句可改為：
You should pronounce this word as your teacher does it.
I have done it as it should be done.
Do in Rome as the Romans do.﹝入鄉隨俗。﹞
He acts as if he were crazy.
* "as if"意指「恰如﹝並非完全一樣﹞」。
* "as if" 從句的動詞用假設語氣，因此用 "were"。
不過，在現代口語，有時亦用直說方式﹝現在時態、過去時態、
未來時態等﹞代替假設方式﹝過去時態、過去完成時態﹞。
假設方式強調「非現實性」，直說方式則著重「可能性」。
以前，英文文法規定，在 as if 從句中要用假設方式，例如：
It looks as if it would rain.
現代英文文法漸改用簡潔的直說方式，例如：
It looks as if it will rain.
The baby laughed as if he had understood your expression.
He speaks English as though he were an Englishman.
* "as though" 意指「恰如」。
They talked as though they had been friends for years.
