阅读理解。 Our winter is very long and cold. The first frost(霜) of the season usually comes about the middle of August. Soon the leaves on the maple (枫树) and oak (橡树) trees on the hillsides turn red, yellow, and brown,  forming a mass of color too beautiful to describe. Gradually(渐渐地) the leaves fall from all the trees except the evergreens (常青树). The earliest snowfall in the Green Mountains usually comes in October. Before Christmas, deep snow sometimes covers the fields and mountains. Then I have fun. I coast(滑行)on my long sled(雪橇)down the steep (陡峭的)hills or go on my skis.After a heavy snowfall, I go for long walks on my snowshoes. All winter the ponds(池塘) and streams(溪流) lie under their roofs of ice while I skate on them. Late in March the snow begins to melt (融化), the ice breaks, and our long winter gives place to spring. 1.
