only if:只有、除非,意思相当于unless,但用于肯定句,引导条件状语从句:I will go only if you go with me.除非你跟我一起走,否则我就不走(只有你跟我一起走我才走).
比较:unless,用于否定句:I won't go unless you go with me.
If only:只要,引导条件状语从句:If only it clears up,we'll go.只要天一放晴,我们就走.
要是……就好了,引导独立句:If only you had won the game!你要是赢了该多好啊.
Only if 用于句首,用倒装语序,Only if a teacher has given permission is a student allowed to enter this room. 只有得到老师的允许,学生才能进入这间教室。
if only: 但愿 表示对现在和将来的愿望,或与过去事实相反的愿望。 If only it would stop raining 真希望雨能停。
一、if only的用法。
if only后面跟的是虚拟语气的句子,表示与事实相反的假设。

If only that photograph weren't missing. 要是那张照片没丢失该多好。
二、only if的用法。
only if后面跟条件状语从句,用陈述语气,后面用部分倒装句,be动词、助动词和情态动词放在主语之前,表示一种充分非必要条件,意思是只要。
