虚拟三加一（特殊句）

  • if 引导的非真实条件状语从句(一张表格3格易错点)
    易错点:
    1.如果if从句（现在/将来）be –> were
    2.if省略，从句要部分倒装(出题人的题干)
    3.混合虚拟（if ____ yesterday,____ now）
If 从句 主句
现在 一般过去式 would/should/could/might+v
过去 had done would/should/could/might+ have done
将来虚拟 一般过去式/were to do/ should +v原型 would/might/could/should+ v原型
