Very summer with my parents, i go to the forest. this is the most interesting and amazing place on earth. walking along the forest paths, we enjoy the silence, the singing of birds, the smell of flowers. plants in the forest impress us with the forms, colors can attract insects, birds, animals, unusual fruits and seeds. world of plants is diverse and very difficult. bright colors give way like a kaleidoscope! strange shapes of trees, shrubs and grasses is wound at times poetic and artistic images.i like to pick raspberries, strawberries, rosehips, mushrooms. i love nature!

  everybody doesn`t know about what will be in the future. but i`m sure, our future will be innvation.   at first , we`ll live in world of innovation technology. computers will be on desks at all school! so, children won`t read books. they will forget about books! also. they`ll forget about normal communicate. i thikk it`s horible!       i think teachers will be robot in the future. it isn`t  right. becouse the teacher is profession.      also, a lot of the biggest fabric and industrial organisation will poiiut ecology ahd air. our planet will be a lifless stone globe. we won`t see the  different animals and the green plants.    that`s what i think about life in the future. and i hope that people around  think about it too
