Last Friday I took the subway home as usually. Since our physics teacher had just teach us in class that the escalator£¨×Ô¶¯·öÌÝ£© worked, I decided to see how fast the escalator went. To my surprise, it went a speed of about 40 m/min. The next day, I went to a department store with her cousin Emily. I times the escalator here too. I found that it was much slower, going about 30 meter every minute. Why? I check on the Internet and found the reason. Stores slow down escalators on a purpose, allowing customers more time to looking at their products.

This semester the sports meeting hold in our school was unforgettable. Our class attended the opening parade, for that we had made a lot of preparations. Our parade took on the shape of the letter ¡°V¡±, which indicated victory for them. To our excitement, our parade performance was great success. As usual, the games started before the opening parade. My classmates attended a lot of event such as running, high jump and long jump. Due to the hard training the athletes had done before, their performances were particular impressive. On the stand, we applauded and cheer for the athletes, some raise their cameras to capture the exciting moments. Finally, the result was announced. It was amazing that our class came first. Our efforts were paid off!
