On Wednesday, we learned about some Google service(tasks on Gmail and Google Books)and added some reference books for book review of summer reading to Google Books. In Rab's class, it is important to work with computer. Students can edit and share their assignments in everywhere and everytime if they use online services. It makes our writing easier and faster. And other benefit of using web services is that they do not depend on OS while Microsoft Word requests Windows. I use Windows and Linux at home. And when I work with Google Document, I can do as same. For this two reason, working online is good for everyone.
