求翻译：室内的光线是可以人为营造的，对于开窗率比较大的房间来说，不妨采用不同图案的纱质窗帘，这样当光线透进来时，光影会发生变化，使得空间层次变得丰富。这样的空间如果不需要私密性或者遮光，那么单层的窗纱就足够了。是什么意思？

Indoor light can be artificially created, for ventilation rates than larger rooms, and may wish to adopt a different yarn quality curtains of the pattern, so that when the light came in, the light will change, makes it rich spatial level. This space if you do not need privacy or shading, flat screens would have been enough.
