The rain in Suzhou

It has rained often in recent days. June and July are rainy months in every year. I cannot sleep well because my bedding and mattress are wet. When I go to work, I must bring the umbrella or the raincoat. also I cannot wear a skirt either.
People often go out on tours with their families, but they cannot go because of the rain these days.  Instead, they must watch TV , play on the computer and cellphone. Actually, I like the rain, because it cleans the air, but I do not like it when it rains everyday.

Your basic syntax and grammar are good.  The phrasing needs work, though.  Also, remember to put a space after every period or comma.
