0216 If you open the door you will get a surprise. 条件句

细读以下句子:
在这一类条件句中,if 从句谈论想象的情况,主句则推测想象的结果。在从句中要用动词的过去时,这并不表明过去的某一特定时间或过去某一动作,因此常被称作“非真实的过去”,整个条件句也被称为非真实条件句。如果 if 从句中的动词是 be,那么应该在第一和第三人称单数名词之后用 were。 * If you went to the exhibition you would enjoy it. * If you saw him now you wouldn't recognize him. * Would he get annoyed if I told him about it? * If I were in your position, I would act differently. * He would help you if he were here. * If you could make him change his mind, you would save him a lot of trouble.
