1 Explain usage and formation of Present Simple tense (affirmative, negative and interrogative) and make up sentences

6.Explain formation of 4 Parts of Speech (noun, adjective, adverb, verb) and give examples
Sure! Here's an explanation of the four basic parts of speech in English grammar and some examples for each:
Noun: A noun is a word that represents a person, place, thing, or idea. Nouns can be either singular or plural, and they can also be concrete (such as a chair or a book) or abstract (such as love or freedom).
Examples:
Person: John, teacher, mother
Place: New York, park, beach
Thing: car, computer, phone
Idea: democracy, freedom, love
Adjective: An adjective is a word that describes or modifies a noun or pronoun by providing more information about its size, shape, color, quality, or other characteristics. Adjectives can be placed before or after the noun they modify.
Examples:
Size: small, big, tiny
Shape: round, square, rectangular
Color: blue, red, green
Quality: beautiful, delicious, expensive
Adverb: An adverb is a word that modifies a verb, an adjective, or another adverb by providing more information about how, when, where, or to what extent the action or description is happening. Adverbs can also be used to show frequency, degree, or attitude.
Examples:
How: quickly, slowly, loudly
When: now, later, yesterday
Where: here, there, outside
Degree: very, extremely, somewhat
Verb: A verb is a word that describes an action, occurrence, or state of being. Verbs can be either transitive (when the action affects an object) or intransitive (when there is no object), and they can be used in different tenses to show the time and continuity of the action.
Examples:
Action: run, write, eat
Occurrence: happen, occur, appear
State of being: be, seem, feel
Overall, understanding these four basic parts of speech and their different forms and functions is essential for mastering English grammar and effective communication.

7.Explain usage and formation of Present Perfect Continuous tense (affirmative, negative and interrogative) and make up sentences
Sure! The present perfect continuous tense is used to describe an action that started in the past and is still ongoing at the time of speaking. It emphasizes the duration of the action and often suggests a connection to the present. Here are the formations and some examples of the present perfect continuous tense:
Affirmative: Subject + have/has been + verb (ending in -ing)
I have been studying for three hours.
She has been working on her project all day.
We have been practicing our English conversation skills.
Negative: Subject + have/has + not + been + verb (ending in -ing)
I haven't been exercising regularly lately.
He hasn't been taking his medication as prescribed.
They haven't been paying attention to the teacher's instructions.
Interrogative: Have/has + subject + been + verb (ending in -ing)?
Have you been practicing the piano every day?
Has she been attending her online classes regularly?
Have they been enjoying their new hobby?
In all cases, the verb form "been" indicates the present perfect continuous tense, and the verb in the -ing form (also called the present participle) indicates the ongoing action. The auxiliary verb "have" or "has" changes depending on the subject of the sentence.
Overall, the present perfect continuous tense is useful for talking about actions that started in the past and are still ongoing, and it can be used in a variety of contexts to express duration, progress, and continuity.
