"ing"

0 Peco, 02br
00I am really confused in use of " ing" form too, can you also help alittle? 02br
02br
00I know a word add "ing" is doing something at the present. Like walking, talking, joking, lauging, doing, going, paying. 02br
02br
00However, i see "ing" form is using as adjective purpose too, Like " he has a good living condition". " This is a 'interesting book'" . 02br
02br
00So, how to do i avoid the confusion use between adjective and action? 0-
