I went back to China as soon as school was over at the end of June. And I returned to Canada on August 17th.

It’s       to go back to China this summer, because of the A（H1N1）flu. Everybody seemed to be      . The easiest thing for us to do was to wear masks（口罩）on the plane, as my mom suggested. However, it was not     to wear a mask for ten hours. I decided to put the masks into my bag      wearing them.

Everything seemed OK       the flight. I saw only five people wear masks all the time. When we arrived in Beijing, some       came into the plane and took our temperature. Fortunately,       had a fever. Therefore, I was able to get home on time.

It’s always wise to listen to your mom’s suggestions.
