| On April 19, we were told to leave school and stay at home because of a new disease called SARS. We started an unusual holiday. It's not very 1 for us to stay at home all day. I think going to school is much better than staying at home, although (虽然) our classes are sometimes 2 . It would be good to see my classmates because I started to 3 them so much. After two weeks, my parents took me to the Great Wall. I felt 4 when I was able to be outside again. It was not crowded (拥挤的) there because 5 people were leaving their houses. My school had asked me to do a special job during this unusual holiday. Every day I 6 ten of my classmates and asked them to take their temperature. I also asked them if they had done their homework. Then I gave the 7 to our teacher. This was a lot of fun. I had 8 made so many phone calls to my classmates before. It's the end of the month now. 9 knows how long this holiday will last. When we go back to school, I 10 everything will return to normal (正常), and SARS will never come back again. | ||||
