西班牙语母语者常犯的错误
A common mistake for Spanish speakers is trying to translate numbers directly. For example, saying ten and one instead of eleven. Remember that eleven, twelve, ， 和 twenty are unique words in English.
Another mistake is confusing the -teen sound (like in thirteen) with the -ty sound (like in thirty). For numbers 13 to 19, always use -teen. Pay attention to the stress in words like thirteen (stress on ‘teen’) versus thirty (stress on ‘thir’).
