1) she (come) already from school. Now she is doing her homework. 2) what are you doing here? I (wait) for 2 hours. 3) we (solve) already the problem. 4) they (know) each other since their childhood. 5) we (sit) here for 25 minutes and I'm not going to wait anymore. 6) it (snow) for 2 days. 7) my father (never/be) to Spain. 8) it is the most delicious cake I (ever/taste). 9) my parents (build) the house for two years. 10) you look exhausted! What (do)?
