I learned that there are external commands and internal commands

me@host:~$ time pwd
/home/gaowei

How could retrieve a list of all the internal commands. Are there distinction between internal commands and builtin commands?

The builtins could be retrieved by

me@host:~$ enable -a | cut -d ' ' -f 2 | nl
 1 .
 2 :
 3 [
 4 alias

 9 caller
 10 cd
 11 command
 12 compgen
 13 complete
 14 compopt
 15 continue
 16 declare
 17 dirs
 18 disown

command-line

  There's a distinction between shell builtins and keywords - in fact the example you chose (time) is one of the latter - see for example the difference between compgen -b and compgen -k
