A flood hit Beijing
A storm hit Beijing around 1:00 pm on July 21, 2012. My classmates and I were learning DIY course, and the teacher told us to go home as soon as possible. We held together an umbrella, but the rain kept going around us. Unluckily, we lost the umbrella in the wind, and both of us almost fell down; Finally we arrived at my uncle's house. What a terrible flood! It washed away small villages and bridges. Houses were collapsed, at least 79 people were killed and many people became homeless. People began to rebuild their homes, and the government has actively taken measures to help people in trouble.
When flood hits our city, we should follow the adults’ advice. Don’t run away or be scared. The electricity and gas should be cut off at once if the flood goes into your house. Keep calm. You can make a difference.
