Translation:I like to go shopping alone by myself.
The English sentence tries to translate the Chinese as directly as possible, but in my opinion this goes too far here, as the English sentence becomes wrong. "I like to go shopping alone by myself." may be okay as an accepted translation, but should definitely not be the default solution.
Is it just me, or does Duolingo keep repeating the same questions in the same unit, even if I get them right?
