现代社会,住房和出行都很拥挤,我希望未来能够充分利用陆海空的空间。在我们房顶的空间,能够修建公路,种上制氧树,无论走多远、飞多高,都不会因为缺氧而限制我们前行的脚步。这样,不仅可以开阔我们的眼界,而且能在旅行中欣赏 In modern society, housing and travel are very crowded. I hope that in the future, we can make full use of the space in the land, sea and air. In our roof space, we can build roads and planted oxygen trees. No matter how far we go and how high we fly, we will not limit our progress because of lack of oxygen. In this way, not only can we broaden our horizons, but also enjoy traveling
