A habit is something that you do often or regularly almost without thinking, especially something that is hard to stop doing．

　　In our daily life, we ought to keep a healthy diet．Also, it’s necessary for us to exercise a lot．And we should learn to make good use of our time．In our school life, we should prepare well for each lesson．In class, we must listen to the teacher carefully．Besides, it’s important for us to do our homework on our own．

　　In a word, good habits can help us learn things better and improve our skills．We can learn to control ourselves if we have good habits．

　　I think good habits are really good for our mind and body．
