求助第15题 为什么不用虚拟语气!不是有it is high time 英语虚拟语气it is time. 虚拟语气句型“it was (high)time that”请问,虚拟语气的句型“it was (high)time that”和“it is (high)time that”在句子表达的意思上有什么区别?请分别举例句说明,谢谢. it is high time for us relected everything 还是 for us to relect..这个it is high time..虚拟语气要用吗 那个不定式的对不低啊? it is high time that 是虚拟语气,后面可加过去时或should do,那是不是所有虚拟语气后都可以加过去时?
