不是同位语 也不是定语从句 是强调句型 参考：结构是：It+be+被强调部分+that+从句 　　强调主语：It is the times that produce their heroes.时势造英雄 　　强调宾语：It is English that Prof.Lin teaches us. ...我知道是强调句型，把强调句型的it is和that划去以后的原句中，那几个是什么成分？for the reason that he has lied to me before （原因状语从句），I don't believe him now（结果，也就是主句。）其中that he has lied to me before是修饰reason的定语从句，reason是先行词。
