The school au thorities won't allow smoking.为什么somke加ing啊 The school au thorities won't allow smoking.后面换成allow to smo we don't allow -----in the library为什么不是to smoke 而是smoking have started smoking 为什么加ing We don't allow/permit smoking in the offices． We don't allow smoking in the reading room. The man doesn't allow smoking这句话是什么意思? Sorry,we don't allow smoking in the lecture room. 为什么run要双写n加ing而allow不用? we don't allow smoking here 改为同义句 Smoking ------ ------ ---- I won't allow by such a thing.allow by 是啥用法啊? Don't somke here 的同义句是否no smoking here
