答案

trees are very inportant for us. when they are alive,they give us O2 and give us good mood.in summer,they can shield the shining and make people feel cool.
after they dead,we can make deskchair,pencils and so on. we can see the things make of wood every well.
some people also use wood to get fire for cooking.
but now, there are less and less trees on earth. our environment become worse and worse.if we do not protect trees, one day,there will be no trees on earth but seed.
