To begin with, let’s take a look at this task 2 question:
These days everyone seems to have more and more possessions (e.g. computers, cars, mobile phones, etc.). Our strong desire to own these things is making us less aware of important personal qualities such as kindness and concern for others.
Do you agree or disagree?
In order to write a decent introduction, you have to locate the fact given in the task, which in this case is the first sentence. Then you need to rephrase and rewrite it in a different way. Try to use “It is true that nowadays“ at the beginning of the sentence. It could be composed like the following statement:
It is true that nowadays more and more people tend to purchase and use possessions such as computers and mobile phones.
Take this one from IELTS Cambridge 8, test 4:
In some countries the average weight of people is increasing in their levels of health and fitness are decreasing.
Do you think are the causes of these problems and what measures could be taken to solve them?
In this case, the whole statement is a fact so we need to paraphrase it in order to write a proper sentence at the beginning of the introduction, a sentence like this:
It is said that nowadays there are countries where the average weight of people has increased while the two key factors of health and fitness have considerably declined.
To be continued.
