— Jenny, how many years have you studied in China?— I ________ here for three years by the end of this month.

It is time that we ____ ready for the final examination.

-----I called you at about half past eight last night but nobody answered. -----Oh, I _____ in my office at that time.

 Don’t call him at this time tomorrow, because he ________ a meeting with his teachers.
