关于if引导的句型都有哪些?

总的来说,if 引导的从句有三种用法1。用于真实条件句例如：If you are at home,I will go to see you。If you work hard at it,you can get success。表示,只要按这样得条件去做,结果是肯定的。2。用于虚拟条件句例如：If I were you,I wouldn't go there。If the sun rose from the west,I would call you Dad。表示,条件是假设的,不真实的,因此,其结果也是不可能实现的。注意句中谓语有所变化3。用于名词性从句,意思等于whether or not 表是否之意。例如：It doesn't matter if you go to attend the meeting。你是否参加会议没关系。
