Look at this paragraph:                                                  ​​​​​​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​អានជាភាសាខ្មែរ
           
            Mr. Bora is a teacher of English at Hun Sen Sa ang High School. He started teaching it in 2005. Now he is still teaching English. So he has been teaching English for 8 years.
The sentence in red type is called the present perfect continuous tense.
           

We form the present perfect continuous tense like this:

Positive form:
Subject + have/has + been + base verb +ING +...

(Base Verb + ING is also called the present participle)



·         They have been waiting for you for hours.
·         Mr. Savery has been running his English part-time classes since 2010.
·         I have been studying how to create a website for a year.

Negative form:

Subject+ have/has +NOT+ been + base verb+ ING + ...

·         My dad hasn’t been painting his room lately.
·         Most teachers of English haven’t been practicing the teacher-center approach for the last five years.


Interrogative form:

Have/Has + subject+ been + base verb+ ING+...?


·         Have you been crying?
·         Has she been waiting for me?
·         Have Miss Thida and you been trying to pass the exam?
Yes/No questions and answers:

·         Have you been doing anything to get oversea scholarship?
Yes, I have   
 No, I haven’t     
·         Has she been practicing English recently?
Yes, she has    
 No, she hasn’t     
@ Note:
Some learners probably don’t know what subjects are used with have, hasor the past participle​ ​of a specific base verb. You must know the spelling of verb + ING, too. If you don’t know these you can’t use the present perfect continuous correctly.
