  4. Hello Liz,

    I wanted to ask you about the video above, which was supposed to be about the use of complex vocabulary. Unfortunately I was unable to watch it since it says that this video is for private use. But from the posts above I can see that students were actually able to watch it online. So, could you tell me if you had changed the option for private use of there is sth wrong with my browser. If yes it is private, can you tell me if there is anyway I could still watch it?

  5. Hello, Liz . thanks for your wonderful explanations , please can you help how to listen your video ,how to write a complex sentence .

    • Sorry, I have removed this video in order to film it again. Meanwhile you can watch the 4 main sentences video.
      All the best

  6. Hi Liza
    Thank you for your great efforts, we highly appreciate that.
    do you have a complete course for IELTS?
    so we can purchase it or attend it in UK.
    Kind regards

  7. Hi Liz,
    Greetings from Bangladesh ! I must say this is a very informative blog for all levels of people practicing IELTS at home. But in this video, you have placed 2000 erroneously, in between 2009 and 2010 in x-axis. Otherwise everything is okay.
    All the best.

  8. Hi Liz.
    Can I put this information in the introduction?

    • This information is for the body paragraphs which contain the detail. Please see my model task 1 on the writing task 1 page.

  9. Hi Liz,

    Not to be rude, in your clip, I saw you used “the amount of people” to rephrased “the number of people” in the description. Is there any explanation for it?

    Many thanks!

    • Hi Thanh, I’ve been meaning to remove this video and replace it. While some people use “amount ” relating to people (it is increasingly common these days), there are examiners who won’t accept it so I must remove it. Sorry, for the confusion.

    your lesson is very interesting . do you have lesson for both of bar chart pie chart . thanks

  11. Hi Liz,

    Can I write ” The amount of people decided to start a vegetarian diet ” rather than ” The amount of people deciding to start a vegetarian diet “??
    Thank you so much.

  12. Hello Liz,
    Its a wonderful site to learn and prepare for IELTS.It would be grateful if you could help me in clarifying some doubts which I have in your lessons.I do have a dilemma whether to use “amount” to indicate people and the other one is ” units are measured”[though it happened in the past years 2000].Please explain how could it be possible.

    • It is best not to use “amount” with people. “Units are measured in ” is always written in the present passive because it refers to the current graph seen on the page.
      All the best

  13. Hi Liz,
    The complex sentence you taught in the line graph is quiet intresting but i have been wondering on where to incorporate it in the writing ,because in the overview, we cannot start giving figures and i know it is not for the body paragraphs.Eassy one does not permit include conclusion so that leaves out the paraphrased introduction as the only option if am right. Now do we start including this figures in our introduction.

    • Hi,

      That’s right, there is no data usually given in an overview unless there is a total to give, for example in a table. In the body, however, you must give detail and support the sentences with data. For a line graph, the detail will be information about the changes that occurred over the given period. So, the sentence from this video is for the body paragraphs. Here is a link to previous lesson which shows how the detail would be written using such similar sentence structures:
      All the best

  14. thanks a lot

  15. That helps me much. Do you have lesson for bar charts because I have problem with it?
