This is a composition of one of my students.
The kitchen in my house is always very greasy. Even the kitchen ventilator can't do much to solve this problem.
I've been worried about my grandmother's health especially her lungs because she is in the kitchen cooking everyday. And there's also air pollution while the oil smoke emits directly out of the house.
I'm thinking about the future design of the kitchens. Will it be better if we design a totally enclosed ventilation system, which includes poriferous ceramic tiles, ceiling materials, to drain and centralize the oil smoke though special pipes.
If so, there won't be nuisance grease in kitchens anymore, and we will have a cleaner environment.
I need a better word to replace "poriferous" , is there any other word?
BTW, I'll appreciate any proofreading comments.
