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 Conditional:
The Zero Conditional is used to express a general truth or a scientific fact, which is always true. It refers to a cause-effect relationship that is straightforward and predictable.
Formation: The Zero Conditional consists of two clauses. The first clause uses the present simple tense, and the second clause also uses the present simple tense.
If + present simple, present simple
Examples:
If you heat water to 100 degrees Celsius, it boils.
If it rains, the grass gets wet.
If you mix blue and yellow, you get green.
First Conditional:
The First Conditional is used to talk about a possible situation or event in the future that may happen as a result of a certain condition being met. It refers to a cause-effect relationship that is likely to happen.
Formation: The First Conditional consists of two clauses. The first clause uses the present simple tense, and the second clause uses the future simple tense (will + base form of the verb).
If + present simple, will + base form of verb
Examples:
If it rains tomorrow, I will stay at home.
If I pass the exam, I will go on vacation.
If she misses the bus, she will be late for work.
Overall, both the Zero Conditional and the First Conditional are used to express a cause-and-effect relationship. The Zero Conditional expresses a general truth, while the First Conditional expresses a possible future outcome. It is important to understand their formation and usage to effectively communicate in the English language.
Here are some additional examples of sentences using the Zero and First Conditionals:
Zero Conditional:
If you mix blue and yellow paint, you get green.
If you don't brush your teeth regularly, you get cavities.
If the temperature drops below freezing, water turns into ice.
First Conditional:
If it rains tonight, we will have to cancel our picnic.
If you study hard, you will pass the exam.
If I have time, I will go to the gym after work.
It is important to note that the use of "if" in these conditional clauses is interchangeable with "when" in some cases. For example, "When it rains tonight, we will have to cancel our picnic" has the same meaning as "If it rains tonight, we will have to cancel our picnic."
Overall, understanding the Zero and First Conditional clauses is important for effective communication in English, as they are commonly used to express cause-and-effect relationships and possibilities.
