下面是答案：

# application.rb 

# rails will fallback to config.i18n.default_locale translation 
config.i18n.fallbacks = true 

# rails will fallback to en, no matter what is set as config.i18n.default_locale 
config.i18n.fallbacks = [:en] 

# fallbacks value can also be a hash - a map of fallbacks if you will 
# missing translations of es and fr languages will fallback to english 
# missing translations in german will fallback to french ('de' => 'fr') 
config.i18n.fallbacks = {'es' => 'en', 'fr' => 'en', 'de' => 'fr'}
