The IELTS speaking exam is suppose to represent what it is like to talk to someone in a real life situation. You should therefore not practice IELTS past paper topics and just talk normally to someone instead. There are thousands of past paper questions and it is very unlikely that you will be asked any of them in your test.
We strongly suggest that you must find someone to practice your English with and talk about something you are interested in or discuss the up-to-date topics in your oral exam. This will make it much easier and you are less likely to get bored.
You will learn the language better if you practice it often, we recommend every day. You will probably agree with the idea that the more you do something, the better you will get at it, right?
But, what if you can’t really speak/practice the language? Because you’re in your home country and nobody speaks it. Well, that’s not always true. Check online see if there are some meet-ups or other similar events where people just want to exchange languages. Another method is to talk to yourself, some people do it in the shower, think about conversations you may have had in this language before or from whatever textbook you use to learn. And repeat it to yourself, then go with other scenarios. Imagine simple day to day conversations, practice the way you would approach them. And if ever you get stuck, you know what the next thing you need to learn is. Just talk, even if it means talking to yourself.
Our strong recommendation is to try to connect with English speaking people. Surely, there are bunch of online school out there who offers variety of courses. Try to enroll and make friends with your online tutor, so you can practice conversational English and IELTS at the same time. You already have plenty of Chinese friends. Now would be a great time to diversify the types of people you associate with. This may seem extremely awkward for you at first, but you should push yourself in that direction for your own good.
You shouldn’t be afraid or embarrassed of speaking the language you are trying to learn. You’re learning the language, you don’t know it yet. You’re going to make mistakes, accept it. Only when speaking the language will you be able to play around with new words or grammar you have learnt. You will get comfortable talking the language, even with mistakes. It doesn’t matter in the end – people will always appreciate your efforts and they will not care about mistakes you might make, because these mistakes are part of who you are and the way you communicate. Embrace them and conversations will flow normally.
