We use the Present Continuous Tense to talk about activities happening now. Examples    The kids are watching TV.    I am sitting down, because I am tired.    I am not learning German, because this is an English class.    Who are you writing to? We can also use the Present Continuous Tense to talk about activities happening around now, and not necessarily this very moment. Examples    Sally is studying really hard for her exams this week.    I am reading a really interesting book now.    How are you brushing up on your English for the trip?    We aren't working hard these days. The Present Continuous Tense is also used to talk about activities happening in the near future, especially for planned future events. Examples    I am seeing my dentist on Wednesday.    Polly is coming for dinner tomorrow.    Are you doing anything tonight?    We aren't going on holiday next week.

present continuous

Now that we know the gerund, we are ready to learn the continuous time, with which we will be able to express more complex ideas.
This English lesson is devoted to the present continuous tense that expresses actions of this but with some nuances that distinguish this simple.
Before seeing how to use the present continuous, let's see how it is formed. Then see how denying this tense and how to form questions with it.
Below is a table showing the continuous present tense. From this table we will see how this time verbal forms.

Use the present continuous
This tense can use it to express different things and in different circumstances:
To refer to actions that are being developed at the same time it is spoken.
I am reading a book -> I'm reading a book (in right now)We also use the present continuous to describe things that happen around the time that we are talking about.
She is studying Español -> She is esstudiando English (not just now)We can use the present progressive to refer to actions that have taken place with some Freq.
You are always working -> You are always working (it does frequently)When we speak of a future action we have already decided that we will develop. In this case we mention the time in which we will develop the action.
I am going to Madrid next week -> I'm Madrid the week bieneNegation and interrogation of the present continuous
To deny this continuum we have to place the particle not between the auxiliary and main verb. For questions we have to first aid and then the personal pronoun.
I am not eating now -> I'm not eating nowAre you eating? -> Are you eating?

simple past when to use

We use the simple past tense to talk about an action or a situation - an event - in the past. The event can be short or long.

Here are some short events with the simple past tense:

The car exploded at 9.30am yesterday. She went to the door. We did not hear the telephone. Did you see that car?
past	present	future
The action is in the past.

Here are some long events with the simple past tense:

I lived in Bangkok for 10 years. The Jurassic period lasted about 62 million years. We did not sing at the concert. Did you watch TV last night?
past	present	future
The action is in the past.

Notice that it does not matter how long ago the event is: it can be a few minutes or seconds in the past, or millions of years in the past. Also it does not matter how long the event is. It can be a few milliseconds (car explosion) or millions of years (Jurassic period). We use the simple past tense when:

• the event is in the past
• the event is completely finished
• we say (or understand) the time and/or place of the event

In general, if we say the time or place of the event, we must use the simple past tense; we cannot use the present perfect.

Here are some more examples:

• I lived in that house when I was young.
• He didn't like the movie.
• What did you eat for dinner?
• John drove to London on Monday.
• Mary did not go to work yesterday.
• Did you play tennis last week?
• I was at work yesterday.
• We were not late (for the train).
• Were you angry?

Note that when we tell a story, we usually use the simple past tense. We may use the past continuous tense to "set the scene", but we almost always use the simple past tense for the action. Look at this example of the beginning of a story:

"The wind was howling around the hotel and the rain was pouring down. It was cold. The door opened and James Bond entered. He took off his coat, which was very wet, andordered a drink at the bar. He sat down in the corner of the lounge and quietly drank his..."
