The photo must be taken in the late autumn.The moss is the only alive plant which we can see in this picture.A meander brook flowing down from the mountain plays an important role in the picture .There are a large amount of tree trunks standing around like many bodyguards.Some branches lie scattering .Some is on the brook ,others is on the ground.We can find a big bole lies acroos the brook.There are full of thorns on the surface of the bole.Brown fallen leaves spread everywhere.We can even see some sun spot .No matter how bad the surrounding is,we should believe ourselves we can find the hope.Now flourish woods dispear but we can also find the moss.In deed,a lot of brances and leaves fell down.They will be the nutrition in the second spring.
