The present perfect tense indicates completed activities in the immediate past. It also expresses past actions whose time is not given and not definite.

Instances of the same are:

• He has gone out.

• I have just reached home.

• They have been to New York.

The present continuous tense is used for an action going on at the time of speaking, as:

• She is riding.

• They are quarreling.

• I am organising, etc.

   

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.

Instances are:

1.You had gone by the time I came;

2.They had said they would arrive by 10 O’ clock, etc.

The past continuous tense (also called the past progressive tense) is commonly used in English for actions which were going on (had not finished) at a particular time in the past. This tense was formed using two components: the verb BE (in the past tense), and the -ING form of a verb.

The following instances would make it clear:

1.It was raining when they left;

2.I was cooking when the phone rang;

3.They were practicing when it started to rain, etc.
