I Dislike The Terrible Air Quality Here

The air pollution in Harbin, a Chinese city where I live now, is severe and alarming. (do not use "to be" verbs) I could only see a vague outline of a car,a person, or a building in the distance when the dust is blown (do not use "to be" verbs) in the wind and covers my sight (the wind cannot cover your sight. Cover implies intent. When I read the words, "the wind covers my sights", I imagine the wind watches you from the sky and decides to prevent Hu Shu Chang from seeing. So the wind says, "Let's cover her sight so she cannot see." When an object prevents you from seeing, we say the object "obstructs our view." So therefore, you should write: The air pollution covering the city causes the wind to obstruct my view or visability ). Sometimes I have to go outside with (the thing you have to do is not "GO", the thing you have to do is "WEAR") a mask, (therefore, your verbs are in the wrong order [I have to wear a mask to go outside.]) especially on a windy and dusty day. I'm worried about my health when I'm living in a city like this. I must leave off for (how about using the verb move to  or relocate to) another city with a better environment when (word choice is not correct) I graduate from the university here. Besides, the weather in Harbin is inconstant (not the right word to describe weather). Yesterday was a (do not use "to be" verbs) rarely fine day here. The genial sunsine poured upon me and saturated me with its warmth. However, it only lasted one day. This early (we do not usually seperate morning into parts but if you must, use phrases like ["At dusk" or "In the wee hours of the morning) morning when I went outside, I could feel the chill of the wind on my body, and I could hear the wind whistling by my ears.

I found a website that has a list of verbs that you can use when you want to show Achievements or Phenomena. The verbs of Phenomena can be reviewed to learn words to use instead of using "to be" verbs all the time.
