Imperativo. Adjetivo calificativo: posición. Comparación de adjetivos.


The imperative mood

The Imperative Mood is used for giving commands. Like the Simple Present Subjunctive, the Imperative Mood of a verb is formed from the bare infinitive of the verb. For instance, the Imperative of the verb to work is work. In the following examples, the verbs in the Imperative Mood are underlined.
e.g. Work!
Work harder!

Likewise, the Imperative of the verb to be is be.
e.g. Be more alert!
You be ready to come with us.

The Imperative Mood can be used only in the second person. As shown in the first three examples above, the subject of the sentence is often omitted when the Imperative Mood is used. In such sentences, the subject you is said to be "understood". In written English, when the subject of the verb is omitted from a command, the command is often followed by an exclamation mark: !

The Imperative Mood can also be used in negative statements. Negative statements are formed using the auxiliary do, followed by the word not. The contraction don't is often used in spoken English. For example:

Without Contractions

With Contractions

Do not work so hard.

Don't work so hard.

Do not be afraid.

Don't be afraid.

To compare people, places, events or things, when there is no difference, use as + adjective + as:

More examples:
