122. What is the weather like in your hometown? ( 5 - 8 )
One of the aspects I could tell you about regarding this topic is that it is very cold in winter, and hot in summer in my hometown Shenyang. What I mean to say is that in winter the temperature often drops to as far as twenty degrees Celsius below zero. During the summer however, it might rise as high as thirty degrees Celsius above zero. In addition, we often get some snow in winter. However, it is not as heavy as in a place like Harbin, which is further north. I am pleased when it snows because the city seems to be clean then. Lastly I would like to mention that we seldom get dust storms here in Shenyang. This is because, unlike a city like Beijing, there are many forests around the city.
