When I review the lab today,I experienced the odd number and even of subnet。I think everybody maybe use it in fact,So I introduce it now for everyone:
        It is actually simple ,use "254"mask(0.254.255.255;0.0.254.255;0.0.0.254 of course ,you should know witch class of network address do you want to match)and 1 or 0.both of them be used to complete the worke.
        For instance :192.168.0.0/24;192.168.1.0/24;192.168.2.0/24;192.168.3.0/24;192.168.4.0/24;192.168.5.0/24……
        Now We  only allow the even subnet to be match ,So We need to do this:
        Access-list 1 permit 192.168.0.0 0.0.254.255 or access-list 1 deny 192.168.1.0 0.0.254.255
 
       The second instance:10.0.1.0/16;10.1.1.0/16;10.2.1.0/16;10.3.1.0/16;10.4.1.0/16;10.5.1.0/16;……Now We only allow odd number of subnet  to be match,So We should to do like this:
       access-list 1 permit 10.1.1.0 0.254.255.255 or access-list 1 deny 10.0.1.0 0.254.255.255
      Another ones look like as above,Everyone need to do it by yourself。
