SA strong Ssand Sstorm Ooccurred Yyesterday Iin Beijing. (This is a diary, not a book or film. You do not need to capitalize evey word.)

My friend and I have to cancel a shopping plane trip because of the terrible weather yesterday. WThe wind was so strong that many trees broke down fell on(to) the street. One of them hit exactly on landed on a car. The colour of the sky turned to yellow. I hope our government could can do something with to help the environment. (I don't see why you wrote this last line, governments helping the enviroment, has nothing to do with the weather. They can not do anything to control the wind, to stop it blowing.)
