Question

是three bamboo还是three bamboos,这时的bamboo可数还是不可数

Answer 1

既可数,又不可数.
bamboo 作为材料时（如区别于 wood 等）不可数；而作为“竹竿”、一棵一棵生长着的竹子时是可数的.但是我们通常说的“一片竹林”则又不可数了.例：
I planted three bamboos in my backyard this morning.我今天上午种了三棵竹子.
I have bamboo in my backyard.我后院里有一片竹林.
Bamboo is often used for building houses in Asia.在亚洲竹子常用来盖房子.
可以说 three bamboos.
