新学期和蟑螂

我今天开始新学期，昨天回到学校。如果今天我没有课，我昨天不会回到学校了。到家呢，我遇到好多蟑螂。昨天杀了十多蟑螂。我用了一个小时多杀了它们。它们的味很丑。我昨天不能开窗，因为是晚上所以蚊子什么的可以进来。我的卫生间是他们的住处。我不能杀了它们在那里，因为会把地上弄脏。

I started the new semester today and resumed yesterday. If I didn't have class today, I wouldn't have come back to school yesterday. When I got home, I met a lot of cockroaches. I killed a dozen cockroaches yesterday. It took me over an hour to kill them. They smell bad. I couldn't open the window yesterday because it was at night so mosquitoes could come in. My bathroom is their place to live. I can't kill them there because they will stain the ground.
