The importance of practice As we all know, "Knowledge is a treasure, but practice is the key to it" We may hear someone say that knowledge can change fates. However, practice is also so significant. Learning to practice is the best way to strengthen knowledge. For example, the book can provide us contents about computer. But if we want to study computer well, we must operate it frequently Besides, you will not improve your oral English although you have mastered the grammar perfectly. That is because you dont't open your mouth to practice it. In the summary, practice is a inevitable part of success. We must take it seriously.
