Combine mount options "bind" and "ro" or "rw".

Try something like this:
# mount -w /dev/hda1 /media/c
# mount -r /dev/hda1 /media/d

Note: Here I have tried to mount a NTFS partition (hda1) from Ubuntu Linux. I have noticed that I can mount a partition many times in read-only mode. But after mounting once (either in read-only or read-write mode) I cannot mount it in rw mode.

mkdir -p -m 0750 /tmp/mount/othermountpoint
mount /dev/somepartition -t auto -o bind,ro /tmp/mount/othermountpoint
mount | grep /dev/somepartition
