Have you ever tried to understand something new on your own but found it a bit too difficult in books or on the Internet?  Don't be worried一you can get help at Khan Academy(可汗学院).
Khan Academy is an online learning website created in 2007 by Salman Khan, an American teacher. In order to provide "a free world-class education to anyone anywhere",Khan offers more than 4,200 free micro lectures(讲座)atkhanacademy.org.

So how can you start your learning journey at Khan Academy?
First of all,enter the website with a personal e-mail account.Your personal home page at Khan Academy is designed to help you learn math. You can take a pre-test first to see your level. The academy then suggests exercises at the right level for you. It also allows you to watch videos and improve yourself until you reach level 5一the highest level.
If you are interested in other subjects, click "LEARN" to see all topics on offer. Try "Art History",for example. This will take you to all the things in that area like text articles, videos and questions. You can also put key words into the search box to see related topics.
Don't worry if you find it difficult to follow the courses in English. The courses have been translated into other languages, such as Chinese.
