The Present Continuous is mainly used to express the idea that something is happening at the moment of speaking. The Present Continuous also describes activities generally in progress (this means that they don't have to take place right now). Another use of the tense is to talk about temporary actions or future plans.

USE 1: Present Actions
Most often, we use the Present Continuous tense to talk about actions happening at the moment of speaking.
Examples:
•    He is eating a dinner.
•    Mary is talking with her friends.
•    They are swimming in the pool.
USE 2: Temporary Actions
This tense is also used for activities continuing only for a limited period of time.
Examples:
•    I'm riding a bike to get to work because my car is broken. Temporary Action (His car will soon be repaired)
•    They are not talking with each other after the last argument. Temporary Action (They will soon make up)
•    Mary is working at McDonald's. Temporary Action (She is working there only during the summer holidays)

USE 3: Longer Actions in Progress
We also use the Present Continuous when we are in the middle of doing something time-consuming (i.e. something that takes time to complete). An example of such an activity is writing a book, saving money or studying for an exam.
Examples:
•    They are working hard to earn money.
•    I am training to become a professional footballer.
•    Mike is studying hard to become a doctor.
•    Elizabeth is currently writing a children's book titled I am the World.

USE 4: Future (Personal) Arrangements and Plans
Sometimes we use the Present Continuous to show that something is planned and will be done in the near future.
Examples:
•    I'm meeting Katie in the evening.
•    He's flying to Rome in September.
•    We're not going anywhere tomorrow.

USE 5: Tendencies and Trends
This tense is also used for expressing tendencies or trends.
Examples:
•    Our country is getting richer.
•    The Internet is becoming less of a novelty.
•    The Universe is expanding .

USE 6: Irritation or Anger
And the last use of this tense is to express irritation or anger over somebody or something in the present with adverbs such as: always, continually or contantly.
Examples:
•    She is continually complaining about everything!
•    Johny is always asking stupid questions!
•    My boss is contantly critising me!
