【简答题】

Bamboo flooring(竹地板)is a growing trend in home flooring and is also a great improvement to traditional hardwood floors.It is the most environmentally friendly kind of natural flooring that you can select for your home.It is also a renewable(可再生的)resource,is stronger than steel,and does not suffer from problems as a result of temperature changes. Bamboo is one of the fastest growing plants on earth,and only takes five years to grow to form.Bamboo is harvested every five years,and starts to re-grow immediately after being harvested.For this reason,bamboo is a kind of grass,not a tree.Bamboo is hollow(空心的)but very hard and can stand up to 50,000 pounds of pressure per square inch. Bamboo flooring has become very popular with its rich and beautiful golden earth colors.But it is important to shop around for a good-quality bamboo flooring product that contains no formaldehydes(甲醛),which is said to be the best kind of bamboo flooring.Many brands use cheaper bamboo that may contain formaldehydes,and this can cause indoor air pollution problems as certain chemical materials in the bamboo slowly release their pollutants into the air. So,why should we turn to bamboo to save the enviroment?In fact,bamboo cannot save the environment directly,but it is an excellent replacement product for much of the hardwood species of trees that are being harvested in rainforests.Once harvested,if these hardwood trees do grow back,it can take up to 200 years!Rainforests are the lungs of our planet and they make a significant contribution to global oxygen production. By selecting bamoo flooring,you can reduce the demand for hardwood materials and help save the environment for future generations.Of course,everyone wants to buy good-quality bamboo flooring.The brands(品牌)from our shop are very high in quality and have received a lot of public praise. 小题1:Bamboo is a kind of grass because _______.
