First Conditional
Condicionais são frases que trazem uma condição para que algo aconteça, ou a possível consequência de determinada atitude que você ou alguém tomar.
Na primeira condicional, ou condicional 1, a oração principal fica no futuro simples e a subordinada, no presente, com "if".
A estrutura é a seguinte:
- If + sujeito + verbo no simple present + sujeito + will + verbo.
- If + we + dump all sorts of chemicals into rivers + we + will + die soon. (Se nós jogarmos toda sorte de químicos nos rios, nós iremos morrer logo).
Mas pode apresentar ordem inversa:
- Sujeito + will + verbo + if + sujeito + verbo no presente simples
- Soon the Earth’s resources + will + be exhausted + if + the human population + continues + to grow.
A negação se dá na frase principal (a com o "will"), seguindo a seguinte ordem:
- If + sujeito + verbo no simple present + sujeito + will + not + verbo
- If + we + dump all sorts of chemicals into rivers + we + will + not + be able to swim in them in the future. (Se nós jogarmos toda sorte de químicos nos rios, nós não poderemos nada neles no futuro).
Mas se você quiser passar a subordinada para a negativa, basta usar o auxiliar "do not"/"does not".
Na interrogação, o Will vai para a frente do sujeito:
- Will + sujeito + verbo + if + sujeito + verbo
- Will + we + be able to swim in the rivers + if + we + continue to dump all sorts of chemicals in it?

Second Conditional
Na Second Conditional ou segunda condicional, a oração subordinada é escrita no passado simples e, na oração principal, usam-se verbos modais, seguido de um verbo no infinitivo.
A estrutura é a seguinte:
- If + sujeito + past simple + sujeito + modal verb + verbo infinitivo.
- If + we + consumed less, + we + would + produce less waste material. (Se nós consumíssemos menos, nós produziríamos menos resíduos).
Os modal verbs são:
- would (iria);
- might (poderia);
- could (poderia); e
- should (deveria).
Assim como na first conditional, a interrogativa ocorrerá na oração principal, que contém o verbo modal:
- If + sujeito + past simple + modal verb + sujeito + verbo infinitivo.
- If + we + consumed less, + would + we + produce less waste material? (Se nós consumíssemos menos, produziríamos menos resíduos?).
Na oração negativa, o "not" vem após o verbo modal. Para deixar a frase subordinada na negativa, basta usar o auxiliar did not:
- If + sujeito + did not + sujeito + verbo modal + not
- If people really didn't care about the environment, they would not try to save it.
