与过去、现在、将来实施相反都怎么用？举几个例子说明。
我就要if only 的用法,别弄那么多没有用的!
与过去事实相反,后面什么时态?与现在事实相反,后面什么时态?与将来事实相反,后面什么时态?
1、if only在虚拟语气中时态倒退一格，与过去事实相反，后面跟过去完成时，had+过去分词。
2、If only I were a boy= I wish I were a boy
if only
读音：英 [ɪf ˈəʊnli] 美 [ɪf ˈoʊnli]
释义：(与过去时连用，引出一个相对合理的理由)即使仅仅为了，只要。
例句：
If only someone could help me!
有谁能帮助我就好了！
扩展资料
if only的近义词：so long as
so long as
读音：英 [səʊ lɒŋ æz] 美 [soʊ lɔːŋ æz]
释义：只要。
语法：as long as 用于本义表示“与……一样长”时，与 so long as 在用法上是有区别的，即 as long as 可用于肯定句或否定句，而 so long as 只用于否定句，不用于肯定句。
例句：
This offer is open to all comers, so long as they own a home.
该条件适合于有住宅的所有申请者。

1．条件句中：

用一句话，以你要求的几种时态的虚拟语气：我要是在这儿就好了。
现在时：If only I were here.
过去时：If only I had been here.
将来时：If only I would be here.
动词向前推一个时态。
现在时：If only I were here.
过去时：If only I had been here.
将来时：If only I would be here.
动词向前推一个时态。
