Нам тут по английскому задали переделать предложения под Present Perfect Continuous, но я не уверена правильно ли я сделала.
1) What you (to do) here since morning?
2) He (to run) for ten minutes without and rest.
3) Have you found your notebook? – No!
I (to look) for it for two hours, but I not yet (to find) it.
4) I (to wait) for you since three o'clock.
5) Ann (to read) for an hour already. She already (to read) sixty pages.
6) My uncle (to have) his bike since his father bought it.
7) I (to write) a letter since came home.
8) How long you (to be) here?
9) We (to know) each other for four years.
10) The (not to sleep) since five.
