The first English week at our school started on May 4th, 2009. The whole school was filled with an English learning atmosphere. A series of activities was held. There were handwriting activities, story writing, English songs, role playing in English, and so on, all the teachers and students were very happy. They spoke English, sang English songs and enjoyed all the activities. Handwriting was for the students in lower grades. Although most of them couldn’t write so well, they were all very careful about it. In the show window, there were a lot of colorful handwritten papers. They copied some articles from books or newspapers. And then they decorated(装饰) them with pictures in different colors, and some even put their own photos on them. How cute and lovely they looked!

Story writing was for students in Grade 7 and Grade 8. These students are always fond of cartoons, so they got interested in this activity. Reading the stories they made up, all the visitors couldn’t help speaking highly of them.
