读写任务（共1小题，满分25分）

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

During a recent Senior Three English lesson, the teacher caught Xiao Li, a female student, busily typing messages on her cell-phone. To the teacher’s surprise, Xiao Li wasn’t just texting her friends the latest gossip. She was actually blogging about what was being taught in the classroom, sharing her opinions about the information and material with her classmates and other students.

The case aroused a heated discussion among teachers and students city-wide. Miss Li, an English teacher from another nearby school said, “I am amazed at how creative the students can be when writing on their blogs. To me it’s a great way for students to improve their writing skills while writing about personal feelings and experiences.” But other teachers are worried that blog-addiction may interfere with their students’ study.

A supporter and classmate of Xiao Li said, “We love her blog! We all read it each day and can’t wait to see what she writes about next. Her interesting stories and great suggestions on study really help to motivate us. And it adds a little fun to our stressful life.” Another student blogger admitted that he often works late into the night, writing his blog and responding to comments posted there. “Sometimes I don’t even have time to finish my homework. I can’t help myself. I really have a lot to say.”
