2. The PRESENT PERFECT PROGRESSIVE TENSE indicates a continuous action that has been finished at some point in the past
or that was initiated in the past and continues to happen. The action is usually of limited duration and has some current
relevance: "She has been running and her heart is still beating fast." The present perfect progressive
frequently is used to describe an event of the recent past; it is often accompanied by just in this
usage: "It has just been raining."
This tense is formed with the modal "HAVE" or "HAS" (for third-person singular subjects) plus
"BEEN," plus the present participle of the verb (with an -ing ending): "I have been working in the
garden all morning. George has been painting that house for as long as I can remember."Authority for this section: A University Grammar of English by Randolph Quirk and Sidney Greenbaum. Longman Group: Essex, England. 1993. Used with permission.
Generally, progressive forms occur only with what are called dynamic verbs and not with stative
verbs. If you wish to review that concept now, click HERE

4. The Future Perfect tense is quite an easy tense to understand and use.
The Future Perfect talks about the "past in the future".
In this lesson we look at the structure and use of the Future Perfect tense,
followed by a quiz to check your understanding
The future perfect tense is used to describe an action that will have been
completed at some point in the future. It is often used with a time
expression which identifies that point in the future.

5. By the time you arrive, we will have finished the meal and the speeches.
(Note: "By the time you arrive" identifies the point in the future.)
I will have read every magazine in the waiting room before I see the dentist.
(Note: The clause "before I see the dentist" identifies the point in the future.)
Of course, you can also have the negative version, which is formed "will not have" +
"[past particple]":
By the time you arrive, we will not have finished the meal and the speeches.
I will not have read every magazine in the waiting room before I see the dentist.

10. The past perfect refers to a time earlier than before now. It is
used to make it clear that one event happened before another
in the past. It does not matter which event is mentioned first -
the tense makes it clear which one happened first.
Yet, already
Utilizamos los adverbios "already", "just", "still" y "yet" más a
menudo en el presente perfecto, aunque podemos usarlos en
otros tiempos verbales. Estos adverbios se utilizan en referencia
a tiempo y su posición dentro de la oración depende de cuál
