1.last time you tell that ethereal can set my card in promiscuous mode

No.  Ethereal doesn't have any code to put adapters into monitor mode.
if not ,should i set it in monitor  mode before ethereal run.
If you want the 802.11 header and non-data frames, yes.
now i use asus wl-167g to capture data.
See
	http://wiki.ethereal.com/CaptureSetup_2fWLAN#head-83ad8510bbd3f22363d068e1c96f82fd0fcccd31
and the various pages it links to.  For example, it refers you to pages 
of information on various 802.11 cards, which will indicate what chips 
particular adapter cards use and what Linux driver(s) are used with them.
2.i know ethereal can show  802.11 header and non-data frames,but is it 
support automatically without another settig if my adapter support 
monitor  mode.
I think so, but it probably depends on your adapter and the driver used 
for it.
3. when ethereal run ,information that "symbol 'pcap_version' has 
different size in shared object,consider re_linking" is shown. i wonder 
if   mismatching   react to  that i only capture data to and from  my 
adapter.
That's a separate problem, which has nothing to do with the packet 
capture issues you're seeing.
