REMEMBER FORGET 的用法,帮帮我啊
MY mother always frogot the door, but she rememberedwhen
she left yesterday.
用 TO DODOING 填空
我认为都是TO DO

remenber与forget的用法比较简单,我们只需记住这么一点:那就是,后面跟不定式to do表示动作尚未进行,跟动名词doing表示动作业已完成.例如:
MY mother always frogot TO LOCK the door,but she remembered LOCKING IT when she left yesterday.
