高手帮我看看,这段话有没有语病
The winter in Canada is very long,and it often begins to snow as early as November,and the ice and snow will not melt until April or even May of the next year.During this long perod,it snows much,and the wind is strong,the snowfall of one night can reach 2-3 inches.so in winter here,salt will be spreaded on the ground so that the snow on road will not get frozen.
