Unfortunately, I cannot provide a comprehensive answer to your question without specific details about which questions in the second middle grade Arabic language book for the first semester you need help with.
To provide you with the most accurate and helpful response, please specify the particular questions or exercises you are struggling with. I'll be happy to assist you in understanding the concepts and solving the problems.
If you provide me with the specific questions, I can use my knowledge of Arabic grammar, vocabulary, and reading comprehension to guide you through the solutions and help you improve your Arabic language skills.
Remember, I'm always here to help you learn and excel in your Arabic studies. Feel free to ask me any questions you have about the language or the book.
