求英语口语中和写作中常用的连词 或者连接短语

我自己学习时,总结的,还没有结束,分享给你吧!
1.If only and only if
If only
（1）在if only这个短语中,中心词是从属连接词if, 而副词only只是加强if的语气的,因此,if only仅仅是if的一种强化形式,不仅能表达说话人的愿望,而且能表达条件.因此,它同if一样,译为“如果”,也能引出条件状语从句.
Ex：If only they were here now, we would be able to celebrate their wedding anniversary.如果他们现在在这里,我们就能庆祝他们的结婚纪念日了.
（2）if only常常用来表达强烈的愿望或遗憾,因此,主要用在虚拟语气中,用以表达强烈的愿望或非真实条件.常被译为“但愿”、“要是……该多好啊”等.
Ex：If only she could have lived a little longer. 要是她能活得再长一些,那该多好啊!
（3）if only有时也可以写成if…only.
Ex：① If she would only come! 但愿他能来.
② If I only knew! 要是我知道该多好!
（4）if only从句在大多数情况下用作虚拟条件句,但是偶尔也有用在真实条件句的情况.常被译为“只要, 只要...就好” 等.
Ex：He will succeed if only he does his best. 只要他竭尽全力,他就会成功.
Only if
“只有……(才)；只有在……的时候,唯一的条件是……” only if 有时也写成only...if,表示唯一的条件,但是意思不变.
Ex：① I told him he would succeed only if he tried hard. 我告诉他,只有努力才能成功.
② I will only come home if you come with me. （= I will come home only if you come with me.） 只有你跟我一起走,我才回家.
③Yet they could only get the blood if one of the frightened children would agree to give it. 可以改写成：Yet they could get the blood only if one of the frightened children would agree to give it. 但是,只有这些受惊吓的孩子中有人自愿献血,他们才能够得到血.
If only和Only If的用法区别：
从上面的分析,我们还可以看出if only和only if这两个短语都可以用来引导条件从句,表示主句所需要的“条件”,但是两者有差异,主要表现在说话人的语义意图等方面.
（1） If only引导的条件句,通常用来表示说话人对某事所寄予的某种强烈愿望,相当于as long as.它可以独立使用,用来表示由于客观条件限制,为某事不大可能或完全不可能实现而感到惋惜或遗憾的复杂心情,常用虚拟语气.
Ex：If only I were as clever as you!要是我像你一样聪明该多好啊!
（2） Only if 引起的条件状语从句,是一个对“条件”限制更严的“限制性条件状语从句”,表示“只有……(才) ；只有在……的时候；唯一的条件是……”的意思；与if引起的一般条件句相比,它有一种增强主句语势的作用.
Ex：Only if the case is urgent should you call out the doctor in the middle of the night. 只有患者情况紧急时,你才可以在半夜叫医生看病.

3.Only that 要不是, 若非
注意与上短语有相近意义的还有如下一些词组:
