There lived..........(a, an, the) university student near my house. He used to go to university... on, in, with) foot. One day I met him when he .........( was going, went, had gone) to the market. He was in a hurry. I stopped and asked him, Why........ you are running, he was running, are you running)?' In fact the bus had already started.........(because, but, as) some people were left behind. Neither the boy nor his friends...........(was, had, were) able to catch the bus. Everyone........... stranded (were, was, are) on the road. If they were in time, they.........( would catch, will have caught, will catch) the bus without any problem. In this way, the situation made them to regret, regret, regretted) themselves.
