if 引导的都是虚拟语气么?“if”引导的句子,并不等于我们中文的“如果”,而是一种肯定无法发声的假设?
看情况了,有些时候也表示单纯的“如果”,一般if后的从句用一般现在时,主句用一般将来时,主将从现 if Jane goes shopping tomorrow,I will go with them 如果简明天去购物,我就跟她一起去
if涉及虚拟语气的时候,分3种情况：
1.与现在事实相反：从句用一般过去式,主句一般是would/should/could/might+动词原形
if I were you,I would never give up that chance.如果我是你,我绝不会放弃那个机会.（我事实上不是你,与现在的事实相反）
2.与过去事实相反：从句用had+过去分词,从句一般是 would/should/could/might+have+过去分词
if he had been faithful,he might have been promoted 如果他那时忠诚的话,他就可能被提升了（但是事实是他那时不够忠诚）
3.与将来事实相反：从句有动词过去式或should+动词原形或were to动词原形,从句一般是would/should/could/might+动词原形
if it was sunday tomorrow,I would join the party 如果明天是星期天的话,我就会去参加这次聚会（很显然明天不是星期天）
