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

3. Explain usage and formation of Zero and The First Conditional clauses
Zero and first conditional adverbs are used in conditional sentences to indicate the likelihood or possibility of a certain event happening in the future.
Zero conditional adverbs are used for things that are always true or always happen. They are formed by using the present simple in both the if-clause and the result clause. Some common zero conditional adverbs are:
If/when + present simple, present simple Example: If you heat water to 100 degrees Celsius, it boils.
First conditional adverbs are used for things that are likely to happen in the future if a certain condition is met. They are formed by using the present simple in the if-clause and the future simple (will + base verb) or the present continuous (am/is/are + present participle) in the result clause. Some common first conditional adverbs are:
If + present simple, will + base verb Example: If it rains, I will stay home.
If + present simple, present continuous Example: If I have time, I am going to the gym.
Here are some more examples of zero and first conditional adverbs:
If you mix red and yellow, you get orange. (zero conditional)
If you study hard, you will pass the exam. (first conditional)
If it's hot outside, I usually go to the beach. (zero conditional)
If I have enough money, I am going to buy a new phone. (first conditional)
If you don't clean your room, you will not be allowed to play games. (first conditional)
4. Explain usage of The Second Conditional clause and make up sentences.
The second conditional is used to express a hypothetical or unlikely situation in the present or future. It usually takes the following form:
If + subject + past simple verb, subject + would/could/might + base form verb.
Examples:
If I had more free time, I would travel the world.
If she studied harder, she could pass the exam.
If we won the lottery, we might buy a new house.
In these examples, the if-clause expresses a hypothetical or unlikely situation, while the main clause expresses the possible result of that situation.
Other examples:
If I were you, I would take that job offer.
If it rains tomorrow, we'll stay inside and watch movies.
If I had a car, I would visit my family more often.
If you worked harder, you would get better grades.
In all of these examples, the if-clause expresses a hypothetical or unlikely situation, while the main clause expresses the possible result of that situation.
