1.4 Summary: A good title may have a role of “adding the finishing touch” to the whole paper. Titles are the first part of the whole paper which is read by readers. So to every author it is necessary to spend his efforts to work out an excellent title. In addition, the proper expression of authors’ affiliation is also very important.   

2. The “Introduction” of papers
2.1    Functioning Requirements
Introduction is the beginning of the main body of papers. A good introduction could attract the readers, let them continue to read the contents followed or the paper won’t be read further. The history, recent advances, significance,  the present research contents and purpose or aim of the research should be briefly introduced.
2.2  Linguistic Characters
More complex and simple sentences; present, past and the present perfect tenses; passive voice.
For instance,

The role of summer pruning on growth and development of apple trees  is now well established.
