4.great changes in our school lifeI would like to talk about two ways of study in our school. The first way is to study in groups. When we study in groups, we can help each other. We can learn to listen to others and learn how to work together. Also, everyone can have chances to express his or her ideas. The other way we like is to study by ourselves. We can make our own plans for study and learn to make good use of time. We can also learn to think by ourselves. And the most important thing is that we can be the master of our own study.
