テキストを他の静的テキストと置き換えたい場合は、文字列の上書きモジュールをご覧ください。プロジェクトページから：
Provides a quick and easy way to replace any text on the site.
Features
- Easily replace anything that's passed through t()
- Locale support, allowing you to override strings in any language
- Ability to import/export *.po files, for easy migration from the Locale module
- Note that this is not a replacement to Locale as having thousands of
overrides can cause more pain then benefit. Use this only if you need
a few easy text changes.
