Time Expressions
The simple present tense is often used with frequency adverbs and frequency adverb phrases.

In some limited cases future time expressions can be used with the simple present tense as well, most often when talking about scheduled events or intentions.
Formation - Affirmative Statements & Questions
In most cases affirmative statements in the simple present are formed using the infinitive form of a main verb depending on the subject. However when the subject is singular, it is necessary to add –s. If the main verb ends in -o, -ch, -sh, -ss, or -z, we add –es. If the main verb ends in a consonant and -y drop the -y and add –ies. The verb -be is an exception to this rule, the simple present form of the verb -be is either -am, -is, or -are. Affirmative questions in the simple present are formed with the auxiliary verb -do in the simple present tense (-do / -does) placed before the subject and a main verb in the infinitive form. Questions in the simple present tense with the verb -be and modal verbs are not formed with the verb -do, they have their own question forms.

The word -please is normally used along with a command for it to sound polite. We may also use a person's name before giving a command, this is also usually to clarify who the command is for, to emphasize the command, or to make it sound less harsh, this is also not done frequently.
