CONDITION: IF CLAUSES
Usamos frases condicionais para mostrar que uma ideia depende da outra.
As “Conditional Tenses” são usadas em estruturas chamadas de “If-clauses”, onde existe uma correlação entre duas formas verbais, gerada pela expressão “if” (se) “Unless” (a menos que, a não ser que).
Exemplos:
If you said it before, I would buy you some potatoes.
I won’t go there unless you ask me to.
O USO DOS VERBOS MODAIS EM “IF CLAUSES”
• Formas que apresentam ideias no futuro.
Exemplos:
If it rains, we shall (will) stay at home.
If I have enough time, I may go and see Pamela this evening.
If you study really hard, you should enter to EFOMM.
If they don’t come soon, they might miss the train.
• Formas que apresentam ideias no presente.
Exemplos:
If I were you, I would take up a sport to keep t.
If you saved your money, you could afford a holiday abroad.
Observação
Nesse caso acima usamos a forma do verbo “to be” no subjuntivo,
logo a forma correta será: I were, you were, he were, she were, it were, we were, you were, they were.
Algumas gramáticas aceitam, I was, he was, she was, It was.
• Formas que apresentam ideias no passado.
Exemplos:
If I hadn’t come to Rio, we would never have met, darling.
If you hadn’t reacted so quickly, we might well have had an accident.
As seguintes expressões também são usadas para introduzir orações condicionais: “unless (if not)”, “in case”, “provided or providing”, “on condition that” e “supposing”.
Exemplos:
Supposing everyone did like that, (what would happen then)?
Here’s a ten-dollar bill. Don’t spend it unless you have to.
I’ll give you some money in case you need to buy some clothes.
You can go out tonight, provided you have nished your homework.
Observação
A expressão “unless” significa “if not”.
Exemplos:
She will fail the exams, unless she studies harder.
If she doesn’t study harder, she will fail the exams.
Nas “If-clauses”, a inversão do verbo com o sujeito elimina o uso do “if”.
Exemplos:
Had you left earlier, this wouldn’t have happened (if you had left…)
Were I to be invited, I would go (If I were invited…)
As “Conditional Tenses” são usados com “wish” (desejar).
Exemplos:
I really wish it would stop raining.
She wishes she would have rested more.
Nas “if-clauses” e com “wish”, o passado de “be” é sempre “were”, mesmo na 3a pessoa do singular.
Exemplos:
If I were you, I wouldn’t say that.
She wishes she were married.
