Generally speaking, the English for the second interview is very simple, that is, ask one or two questions in English, or let you read a paragraph in English and then translate it into Chinese. English accounts for a small proportion in the final retest score, and if it is added to the total score, the impact will be even smaller. So don't worry too much now.
Suggestion: focus on re-examination of professional courses, that is the key. Then prepare an English self-introduction, recite two or three commonly used English sentences every day, and rely on it when asking questions. As long as you can speak English, it's not a big deal to be flushed and not say a word.
