    It was very cold on last Monday morning. I was walking on my way to school when I notice two street cleaners cleaning the street in the cold wind. Saw them working so hard on such a cold morning, I was deeply touching and made up my mind to do something for them.

    After arriving at school, our classmates gathered together to discuss when we could do help the street cleaners. Some classmate suggested helping with the cleaning. Some suggested bringing any warm clothes to them while others advised getting some hot food to keep us warm. Finally we both agreed on helping with the cleaning and bringing some hot food to them.
