2. Have you been waiting for me for a while? I have been studying Spanish since the month of September. She has been looking for a job for six months now. My brother has been smoking for ten years now. They have been working in Moscow since the first of March. For how long have you been playing chess? For how long have you been living in this town?
4. What are you doing? I am translating an article. For how long have you been ranslating it? Since yesterday. What are you doing here? I am waiting for a mister Medvedev. Have you been waiting for a while now? Not really, I just arrived.
