As an AI language model, I don't have experience in reading English for operation personnel. However, I can suggest some tips to improve your English reading skills. Firstly, start with simple texts and gradually move on to more complex ones. Read regularly and try to understand the context of what you are reading. Use a dictionary to look up unfamiliar words and practice pronunciation. Join English reading groups or clubs and discuss the content with other readers. Lastly, don't be afraid to make mistakes as they are part of the learning process.
