西班牙语母语者常犯的错误
Spanish speakers often use the infinitive where English uses the gerund, especially after prepositions.
For example, a common mistake is I am good at speak English (incorrect).
The correct form is I am good at speaking English, because at is a preposition, and it must be followed by the -ing form.
Another common error is using -ing after verbs that require to + infinitive.
For instance, I want going home (incorrect).
The correct form is I want to go home, as want is followed by to + infinitive.
