Yesterday, I read a book, the name of the book is《Dr Bethune》.
Dr Bethune was a famous doctor From Canada. In 1938, he came to China. At that time , China was at war with Japan. He worked as a doctor in the Chinese army and saved many soldiers’ lives. He worked very hard and became sick. Dr Bethune died in 1939. He was only 49 years old. He was a good man and we remember him today.
I think the book is very, very good!

How to do research     
                                      -------reading after a science paper   
These days , I am busy preparing my dissertation which is about web usage mining . I read some English papers and learnt much from them .  And now , I want to say something about a paper titled “Web Usage Mining ：Discovery and Applications of Usage Patterns from Web Data”.
This is the first English paper I read about dissertation and gave me great help .
   This paper is a review about web usage mining. It introduced web usage mining in detail . Although it is a little old for it was published in 2000 , its contents are very useful today . It is organized according to the sequence of web usage mining and the six main parts are introduction which tells me what is web usage mining , the sources and abstraction of web data , the three steps of web usage mining , taxonomy and project survey , websift overview , privacy issues . The third and fourth parts are most important .  It had a list of existing project about web usage mining which I saw many times in other papers , but this paper is the one creating this list . Besides , it has been referred for more then twenty times . As we all know that , the higher the referred number is , the more important the paper is , so I consider this paper to be an important and successful one in this region.
    In my opinion , the success of this paper dues to three reasons . The first reason is the profound computer knowledge owned by the authors . Web usage mining relates to  many subjects , such as artificial intelligence , ontology , semantic analysis , but the most basic knowledge is computer science . The four authors are all professors of department of computer science and engineering in university of Minnesota . For myself , I am not major in computer science and I am not very good at computers , so I feel a little difficult to understand technologies used in this region.
