With the    1    (发展) of economy, people are    2    (遭受) more and more     3    (自然的) disasters. Due to the strongest typhoon called “Dussuri”, there was a heavy rain in many areas and it caused great losses,    4    (尤其) in the north China. The roads were    5    (覆盖) with water and thousands of houses were     6     (破坏). In case of disasters, we are supposed to keep    7    (镇静的) and try to escape in time.

The bad weather may have something to do with the worsening of environment. People may think that big things must be done to protect the environment. Many forget protecting it begins with small things. For example, it’s a good idea to use reusable bags instead of     8    (塑料的) bags. You can also save electricity by turning off lights before leaving a room. Never use    9    (木制的) chopsticks when you buy takeaway food. All these small things can add up and make a big     10    (差异).
