Complete List of Present Continuous Forms
USE 1 Now

Use the Present Continuous with Normal Verbs to express the idea that something is happening now, at this very moment. It can also be used to show that something is not happening now.

Examples:

    * You are learning English now.
    * You are not swimming now.
    * Are you sleeping?
    * I am sitting.
    * I am not standing.
    * Is he sitting or standing?
    * They are reading their books.
    * They are not watching television.
    * What are you doing?
    * Why aren't you doing your homework?

USE 2 Longer Actions in Progress Now

In English, "now" can mean: this second, today, this month, this year, this century, and so on. Sometimes, we use the Present Continuous to say that we are in the process of doing a longer action which is in progress; however, we might not be doing it at this exact second.

Examples: (All of these sentences can be said while eating dinner in a restaurant.)

    * I am studying to become a doctor.
    * I am not studying to become a dentist.
    * I am reading the book Tom Sawyer.
    * I am not reading any books right now.
    * Are you working on any special projects at work?
    * Aren't you teaching at the university now?

USE 3 Near Future

Sometimes, speakers use the Present Continuous to indicate that something will or will not happen in the near future.

Examples:

    * I am meeting some friends after work.
    * I am not going to the party tonight.
    * Is he visiting his parents next weekend?
    * Isn't he coming with us tonight?

USE 4 Repetition and Irritation with "Always"

The Present Continuous with words such as "always" or "constantly" expresses the idea that something irritating or shocking often happens. Notice that the meaning is like Simple Present, but with negative emotion. Remember to put the words "always" or "constantly" between "be" and "verb+ing."

Examples:

    * She is always coming to class late.
    * He is constantly talking. I wish he would shut up.
    * I don't like them because they are always complaining.

REMEMBER Non-Continuous Verbs/ Mixed Verbs

It is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. Instead of using Present Continuous with these verbs, you must use Simple Present.

Examples:

    * She is loving this chocolate ice cream. Not Correct
    * She loves this chocolate ice cream. Correct

ADVERB PLACEMENT

The examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.

Examples:

    * You are still watching TV.
    * Are you still watching TV?

ACTIVE / PASSIVE

Examples:

    * Right now, Tom is writing the letter. Active
    * Right now, the letter is being written by Tom. Passive

زمان آینده استمراری، future continuous


Future Continuous

Future Continuous has two different forms: "will be doing " and "be going to be doing." Unlike Simple Future forms, Future Continuous forms are usually interchangeable.
FORM Future Continuous with "Will"

[will be + present participle]

Examples:

    * You will be waiting for her when her plane arrives tonight.
    * Will you be waiting for her when her plane arrives tonight?
    * You will not be waiting for her when her plane arrives tonight.

FORM Future Continuous with "Be Going To "

[am/is/are + going to be + present participle]

Examples:

    * You are going to be waiting for her when her plane arrives tonight.
    * Are you going to be waiting for her when her plane arrives tonight?
    * You are not going to be waiting for her when her plane arrives tonight.

REMEMBER: It is possible to use either "will" or "be going to" to create the Future Continuous with little difference in meaning.
Complete List of Future Continuous Forms
USE 1 Interrupted Action in the Future

Use the Future Continuous to indicate that a longer action in the future will be interrupted by a shorter action in the future. Remember this can be a real interruption or just an interruption in time.

Examples:

    * I will be watching TV when she arrives tonight.
    * I will be waiting for you when your bus arrives.
    * I am going to be staying at the Madison Hotel, if anything happens and you need to contact me.
    * He will be studying at the library tonight, so he will not see Jennifer when she arrives.

Notice in the examples above that the interruptions (marked in italics) are in Simple Present rather than Simple Future. This is because the interruptions are in time clauses, and you cannot use future tenses in time clauses.
USE 2 Specific Time as an Interruption in the Future

In USE 1, described above, the Future Continuous is interrupted by a short action in the future. In addition to using short actions as interruptions, you can also use a specific time as an interruption.

Examples:

    * Tonight at 6 PM, I am going to be eating dinner.
      I will be in the process of eating dinner.
    * At midnight tonight, we will still be driving through the desert.
      We will be in the process of driving through the desert.

REMEMBER

In the Simple Future, a specific time is used to show the time an action will begin or end. In the Future Continuous, a specific time interrupts the action.

Examples:

    * Tonight at 6 PM, I am going to eat dinner.
      I am going to start eating at 6 PM.
    * Tonight at 6 PM, I am going to be eating dinner.
      I am going to start earlier and I will be in the process of eating dinner at 6 PM.

USE 3 Parallel Actions in the Future

When you use the Future Continuous with two actions in the same sentence, it expresses the idea that both actions will be happening at the same time. The actions are parallel.

Examples:

    * I am going to be studying and he is going to be making dinner.
    * Tonight, they will be eating dinner, discussing their plans, and having a good time.
    * While Ellen is reading, Tim will be watching television.
      Notice "is reading" because of the time clause containing "while." (See Explanation Below)

USE 4 Atmosphere in the Future

In English, we often use a series of Parallel Actions to describe atmosphere at a specific point in the future.

Example:

    * When I arrive at the party, everybody is going to be celebrating. Some will be dancing. Others are going to be talking. A few people will be eating pizza, and several people are going to be drinking beer. They always do the same thing.

REMEMBER No Future in Time Clauses

Like all future tenses, the Future Continuous cannot be used in clauses beginning with time expressions such as: when, while, before, after, by the time, as soon as, if, unless, etc. Instead of Future Continuous, Present Continuous is used.

Examples:

    * While I am going to be finishing my homework, she is going to make dinner. Not Correct
    * While I am finishing my homework, she is going to make dinner. Correct

AND REMEMBER Non-Continuous Verbs / Mixed Verbs

It is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. Instead of using Future Continuous with these verbs, you must use Simple Future.

Examples:

    * Jane will be being at my house when you arrive. Not Correct
    * Jane will be at my house when you arrive. Correct

ADVERB PLACEMENT

The examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.

Examples:

    * You will still be waiting for her when her plane arrives.
    * Will you still be waiting for her when her plane arrives?

    * You are still going to be waiting for her when her plane arrives.
    * Are you still going to be waiting for her when her plane arrives?

ACTIVE / PASSIVE

Examples:

    * At 8:00 PM tonight, John will be washing the dishes. Active
    * At 8:00 PM tonight, the dishes will be being washed by John. Passive

    * At 8:00 PM tonight, John is going to be washing the dishes. Active
    * At 8:00 PM tonight, the dishes are going to be being washed by John. Passive

NOTE: Passive forms of the Future Continuous are not common
