Put the verbs in brackets in the Present Perfect (have/has worked), Pre Present Perfect Continuous (havelhas been working) or Past Perfect Continuous (had been working). Since he left university, Mark (prefer) to live alone. For the last four years he (look for) a property to buy, and he (just pay) a deposit on a small flat not far from the railway station. He (save) money for three years before he could make such a decision. But suddenly he no longer knows if he is doing the right thing. Before he graduated from the university, he (live) in a quiet place near the park for 15 years, and he got used to it. Now he is also thinking of getting married. It would be better for his children to walk in the park, not near the station. So, Mark sits down and pours himself another coffee. He (already/have) ten cups today, but he can't find a solution.
