The form for the Subjunctive and Impersonal Expressions is the required 3-part formula.
Impersonal Expressions work in almost the same way that Ojalá expressions work. The first subject is already provided: Es ("It's").
There is a long list of adjectives we can use with Es - most of which require the Subjunctive when followed by que and a change of subject.
For example:
| It's important that she study every night. | Es importante que ella estudie cada noche. |
| It's great that he is coming to the party. | Es bueno que él venga a la fiesta. |
| It's probable that Keanu will eat dinner with us. | Es probable que Keanu coma la cena con nosotros. |
| It's marvellous that Antonio Sabáto is dating our professor. | Es maravilloso que Antonio Sabáto salga con nuestra profesora. |
It doesn't matter if something is important, probable, critical, necessary, good etc. because these are value judgements and not statements of objective fact. It is your opinion of the statement rather than the statement itself which is the focus.
However, statements that express Truth , Certainty, and Fact do not use the Subjunctive.
| Es verdad que mi perro se llama Lucy. | It's true that my dog is called Lucy. |
|---|---|
| Es cierto que los pastores alemanes son perros fabulosos. | It is certain that German Sherpherd Dogs are fabulous. |
| Es hecho que ellos trabajan como perros policías. | It's a fact that they work as police dogs. |
