My friend Herbert has always been fat, but things got so bad recently       he decided to go     a diet. He began his diet a week ago. First of all, he wrote out a long list of all the foods that were forbidden. The list included most of the things Herbert loves: butter, potatoes, beer, milk, chocolate and sweets. Yesterday I paid him       visit. I rang the bell and was not surprised to see that Herbert was still as fat       ever. He     (lead) me into his room and      (hurried) hid a large parcel under his desk.      was obvious that he was very embarrassed. When      (ask) what he was doing, he smiled guiltily and then put the parcel on the desk. His      (explain) was that his diet was so strict that he had to reward     occasionally. Then he showed me the contents of the parcel. It contained five large bars of chocolate and three bags of sweets!
