A different way of teaching is widely used in our English study. Before class, we make study plans first. Then we look up the new words, listen to the recording and read the text. When we meet problems we can't solve by ourselves, we always write them down in our notebooks.
In class, we sit in groups to discuss the problems freely.The teacher always offers help when we need.After discussion, it's time for us to give a report to the class.We also make conversations in pairs and practice a lot.It's really good for our listening and speaking.
After class, we have less homework now so we can go to the library to read English books, magazines and newspapers.We can also surf the Internet for useful information.
In a word, we enjoy the new way of studying.We can make more progress in our study.
