✔ 最佳答案
In an oral examination, what you should try your best to do is to be confident and speak out loud. It is common knowledge that english is not your first language, no one will accuse you for not speaking it properly. Instead you should try to use simple words to at least make sense. On top of that you should be fluent, do not speak in fragments, lastly if you remember some vocabulary that you can top up your speech with that is even better.
Please relax and give it your best!
