What if I don't have one?
If you look at all the prompts of IELTS task 2 more closely in Cambridge IELTS Student's Book, then you will have this instruction:
"Give reasons for your answer and include any relevant examples from your own knowledge or experience." This indicates that stating
an example is a must . Have a look at how the
specific example is used in a paragraph:
Many everyday practices are now performed by machines instead of people and this has resulted in less need for labour. For example, in recent decades nearly all major banks have replaced telephone operators with telephone switchboards that have recorded messages an all bank now have automated teller machines (ATMs). This reduces the need for people to visit the bank itself and has resulted in a corresponding decrease in the need for bank staff. As bank and other similar businesses strive for profit, this is likely to increase unemployment further in the future.This paragraph uses journalistic questions to construct an specific example. Here are:
Who? - banks
How many? - nearly all
When? - over the last few decades
What? - replaced need for telephone operators and bank tellers
How? Using switchboards and ATMs
Result? - people don't need to visit the bank and less staff needed.
Most of the time, my problem is that I don't have opinion about the topic and the result is what you have seen.
If you could, then you'd better read as many samples of IELTS writings in this website as you can to improve your writing skills. Result shows that reading the samples not only gives students some new ideas about different topics, but it also improves their grammatical mechanics and vocabularies.
Hope this help :D
