if you want to turn it off, you should use 0, not nil. See:

• Emacs: How to Turn a Minor Mode on/off/toggle?
  http://xahlee.org/emacs/emacs-tip_mode_on_off_toggle.html

try that see if it address the problem. If that doesn't work, i
suspect it might be a bug, of the inter-relations of the global vs non-
global version...

instead of turning it off for particular modes, possibly more
practical is to turn it on for text related modes.

e.g.

(defun turn-spell-checking-on ()
  "Turn speck-mode or flyspell-mode on."
  (flyspell-mode 1)
  )

(add-hook 'text-mode-hook 'turn-spell-checking-on)

i tried, but it can't work.

i also have tried to use (linum-mode 1) in certain mode like c,
without using the (global-linum-mode t), but i never see linum in c
files.

i think maybe there are some thing wrong in (global-linum-mode t),
because i firstly set it, and later in other mode, disable linum-mode
would be failed.

you are right.

i just tried open a new buffer type something to get some lines and
set it to c-mode and turn on linum-mode, and no line num shows.
However, using global-linum-mode shows the lin nums.

must be a bug. Reporting the bug would probably be helpful.
