In the past, teachers always kept on to explaining the points in class. Our students just listened and take notes. But now we often discuss and try to solve the problems raising by the teachers or ourselves. After class, we enjoy different kind of activities instead of doing endless homework. For example, we can read that we are interested. We can go to the library and surf the Internet for variously kinds of information. In my opinion, exploring study does not only help us learn much, but also make us to enjoy study and become masters of study.
