英语改错题1,We don't allow to smoke here,you 'd better not smoke.

1.最明显的错误是：to smoke → smoking.
allow doing sth 允许做某事；allow sb to do sth 允许某人做某事 → (sb) be allowed to do sth （某人）被允许做某事；但是没有allow to do sth.
逗号的确有问题,不过我估计是印刷错误或题目本身的失误.
2.的确是把will → would
这是一种含蓄的虚拟.
without electricity = if there were not electricity,这是对现在情况的虚拟.
if从句无须说出,直接用without...代替,其后的句子采用“wouild/might/could do sth”做谓语.
因为事实是“现在的人类生活中有电”.

逗号可以强调语气，适合口语。
be 为什么改为would be ？因为虚拟语气

1.allow sb to do sth。allow后加anybody。
2.would be 表推测！

allow to smoke改allow smoking
因为，这是虚拟假设，电已经存在。

1、We aren't allowed to smoke here. You'd better not smoke.
2、will 改为 would be
解释：这里用虚拟语序，“Without electricty”，表示“没有电”，而事实上不是这样是，所以用虚拟语气。
