We set a lot of activities before asking students to begin to write, such as present pictures, brainstorming, and group discussion. Students can get their idea of this topic by doing these. And students’ troubles of vocabulary or expressions were resolved through looking for answer in dictionary, asking classmates for help and teacher’s guidance. So it should not be too difficult for most students to complete the writing task. Then considering the individual differences of students, such as study level, writing speed, thinking mode and combining the accuracy of writing skill, I set 10 minutes to finish the writing. I think that is acceptable.
