May I set the Root of ASTNode to parser by location,say,offset and length?
I only want to parser a line of code.I think I can use ASTVisitor,but
ASTVisitor seems to start at the very beginning of the CompilationUnit
every time.
Any suggestions?

You can use ASTParser.setFocalPosition(..).
This will however scan all statements within a method.

If you want to use this method, you should take the upcoming 3.4M7
build. Two issues have been fixed with this method.

What does setSourceRange(..) mean?
Is it relative to this problem?

No, setSourceRange(...) is called for you by the parser.
