The present continuous tense is used for actions happening now or for an action that is unfinished.
The present continuous tense (sometimes referred to as the present progressive or present imperfect) is the verb tense most commonly used in modern English. It combines the present tense and continuous aspect.
The past perfect tense is used to show that something happened before another action in the past.
The past perfect, sometimes called pluperfect, describes events in the past. This is a specific type of tense and even when it seems hard to use, it is actually pretty easy. This tense describes events that happened in the middle of another event in the past, or which „passed in the past“. To construct the past perfect tense, we need to know all the irregular verbs and their forms.
The past continuous tense is used to describe actions that began in the past and often continued for a short period of time after the action started.
The past continuous (sometimes past progressive) tense is a really important tense used in English. This tense is very often used in daily conversation so it is really necessary to know how to use it.
