Lesson: Infinitive of purpose
Part A
Usamos o infinitivo (to + verb) para expressar o propósito que temos ao fazer algo, para explicar o motivo pelo qual fazemos algo.
Example:
| I called her to explain the situation. |
| We studied to pass the test. |
| I went to the supermarket to buy fruits. |
Eu liguei para ela para explicar a situação. Ou seja, porque eu queria explicar a situação.
Também usamos o infinitivo para falar sobre o propósito de algo, ou porque alguém tem, quer ou precisa de algo.
Example:
| The water is to keep the body hydrated during your workout. |
| She has a dog to keep her company. |
| I want an mp3 player to study at home. |
Podemos usar in order e so as antes de (to + verb) para dar mais enfase em estilos mais formais.
| I called her in order to explain the situation. |
| We studied so as to pass the test. |
Não utilize for nestes casos.
Estaria errado dizer:
| I called her for explaining the situation. | ERRADO |
| We studied for pass the test. | ERRADO |
