### Comments for Usage of the Past Perfect Continuous Tense

 Sep 05, 2015 Past perfect in IELTS Task 1 by: IELTS buddy Hi Serge, I think you are over-complicating things. You need to use the past simple for completed actions in the past, which is clearly the case for (3). As for (1) and (2), it is possible you could use PRESENT perfect continuous, but only if you are referring to a point in the past up until the present. So for example if temperatures have been decreasing from 1995-2015 (this year). But this does not seem to make sense as you are talking about days of the week. I would really need to see the graphs you are referring to. So depending on this, these seem like the possibilities: 1) temperatures have been decreasing 4 celsius approximately since hottest day of the week OR 2) temperatures decreased 4 celsius approximately as of the hottest day of the week 3) The total amount of bike usage decreased between 1960 and 2000.

What tense Should I use in writing task 1?

Because it was observed almost always past tenses have been used in the model answers.

 Oct 25, 2016 Past Simple by: IELTS buddy Hi Chaminda, Yes you will find that it nearly always is in the past, so you will be using the past simple but you should always check the years carefully to make sure. For example, you sometimes get graphs that also include the past and future, in which it is not just the past simple.

## Using the Present Perfect

by Hai Anh

Everything seems correct but these examples make me so confused:

"In general, the employment opportunity has increased till 1970 and has dropped down afterwards."

"The overall sale of the company has increased by 20% at the end of the year."

Why does he use present perfect?

Thanks!

### Comments for Using the Present Perfect

 May 28, 2017 Present Perfect Tense in IELTS Writing Task 1 by: IELTS Hi Hai, Actually strictly speaking that is incorrect. Those are completed actions in the past so they should be past simple. There is a possible argument for using the present perfect. It can be used for something that has relevance to the present moment. For example we say "I've closed the door" if you just closed it and are telling someone who is with you. So if you were describing that graph to someone there with you, you could do it in that way. But really I think most people, and examiners, would expect to see the past simple so to not risk any penalties for someone who views it as wrong I would stay safe and stick with past simple for changes clearly shown to be in the past. You can use past perfect with the word 'by'. So "By 1970 the employment rate had increased by 50%". But that's just one exception.
