Grammary :
We use the present simple to talk about things we do regularly. Facts, habits or routines
For example: I play basketball every Wednesday.
We use the present continuous to talk about things we are doing now. Temporary actions
For example: I am playing basketball at the moment.
The imperative is a verb form that is used to give orders, instructions, advice, encouragement etc. It's formed by using the base infinitive of the verb (the infinitive without to). You don't need a subject.
Sometimes you want to tell someone NOT to do something. This is a negative imperative. In this case you simply add the word 'Don't' before the verb.
Active Voice: Active voice is a grammatical construction in which the subject of a sentence performs the action. In simpler terms, the subject is the doer of the action. Active voice sentences typically follow the subject-verb-object (SVO)
Passive Voice: Passive voice is a grammatical construction in which the subject of the sentence receives the action, rather than performing it. Passive voice sentences typically follow the object-verb-subject (OVS)
The Preterit Tense (also known as the Simple Past)
We use the preterit to talk about actions completed in the past.
For regular verbs in the affirmative, you add "-ed" to the end of the verb in its infinitive form. If the infinitive ends in a consonant+y, the "y" becomes an "i".
Example: I played football. She studied for hours.
Modal Verbs
We use modal verbs to describe the "modality" of another verb, or the way it expresses itself. They tell us the possibility or impossibility of events, as well as the ability the subject has to complete them. Here are some commonly used modals: can, could, should, may, might, must, will and would.
Qualifiers are words that enhance or limit the meaning of the word(s) after it. They express doubt (It seems you understand him) or amplify (The class was very hard).
Here are some common examples of both:
To enhance
To limit
Even
Suggests
Quite
Indicates
Super
Probably
Fairly
Somewhat
