Your English is just fine!
You probably have a corrupt preference file, specifically 'systemuiserver.plist'. But there may be two of them, and it is best to delete your caches as well, so ...
In "/Users/<yourname>/Library/Caches", delete everything
In "/Users/<yourname>/Library/Preferences", delete com.apple.systemuiserver.plist
In "/Users/<yourname>/Library/Preferences/ByHost", delete com.apple.systemuiserver.xxx.plist where 'xxx' is a 12 digit (hexadecimal) numeric string.
Then log out and back in again. You may need to go to System Preferences to put back the menu items you need to display.
Let us know if this helps.
