I installed the latest version of Ubuntu (17.10) , but the problem is, I can't find the menu bars of applications in the GNOME panel. For instance, the Chrome menu bar doesn't appear on the panel like in Ubuntu 17.04 and earlier versions.

You may try a GNOME shell extension called "Gnome Global Application Menu(HUD for Gnome)". It provides a global application menu (i.e. menu bar of an application window in the top bar) à la Unity's global menu.
(screenshot source: extension's homepage at extensions.gnome.org)
For detailed info you may visit the extension's GitHub page.
Warning: Performance may not be as smooth as Unity's global menu. See this if you want to deactivate/uninstall the extension correctly.
Current status and future of the extension
Update: The extension has been discontinued by its original developer. Please consider not using this extension.
