1) How long have you been writing this story? Have you finished it? *Объяснение*: В первом вопросе акцент на процессе написания (длительность), поэтому используем Present Perfect Continuous. Во втором вопросе важен результат, поэтому используем Present Perfect Simple. 2) I haven't met Mr. Webster. I don't know what he looks like. *Объяснение*: Здесь важен факт знакомства, а не его процесс. Знакомство либо произошло, либо нет. 3) We have been learning English for several years. But I can't say we know it very well. *Объяснение*: Упор на длительность процесса изучения, поэтому используем Present Perfect Continuous. 4) They haven't seen/haven't been seeing each other for ages. *Объяснение*: Оба варианта возможны. Первый (haven't seen) подчеркивает факт отсутствия встреч, второй (haven't been seeing) - что они не встречались в течение длительного периода времени. 5) John has lived/has been living in this house since he came here. *Объяснение*: Оба варианта возможны, но немного отличаются по смыслу. Первый (has lived) подчеркивает факт проживания, второй (has been living) - длительность проживания. 6) I have never spoken to Mr. Forrester. *Объяснение*: Важен факт отсутствия разговоров с мистером Форрестером, поэтому используем Present Perfect Simple. 7) Jack has been waiting for his cousin for an hour already. Are you sure she will come? *Объяснение*: Упор на длительность ожидания, поэтому используем Present Perfect Continuous. 8) I have read/have been reading this book up to the end and I find it boring. *Объяснение*: Оба варианта грамматически верны, но с небольшими нюансами. 'Have read' акцентирует внимание на завершении чтения, 'have been reading' – на процессе, который утомил говорящего. 9) We have grown/have been growing grapes on these lands for all our lives and we are going to do it in the future. *Объяснение*: Оба варианта возможны. 'Have grown' подчеркивает результат их деятельности (то, что они вырастили виноград), а 'have been growing' делает акцент на длительности процесса. 10) He has worked/has been working here for 5 years. *Объяснение*: Оба варианта возможны. 'Has worked' подчеркивает факт работы, 'has been working' - длительность работы.
