But even with enough food, O’ Brady began to become     5     (thin) and weaker after six weeks. “I     6     (lose) a ton of weight so far. My legs feel more like the size of my arms at this point,” he wrote on US social media Instagram.

Adding to the pressure, O’ Brady was racing against Louis from the UK. The two men set off together, with Brady     7     (take) an early lead. But on Christmas Day, O’ Brady resolved to make a final effort without stopping for a rest.     8    (lucky) for him he made it, getting to the finish line earlier than Louis.

3 . A housewarming party is a special party to be held when someone buys or moves into a new apartment or house. The person who bought the house or moved is the one who throws the party. The party is a chance for friends and family to congratulate the person on the new home.     1     And it is good time to fill the new space with love and hopeful presents.

    2     Some people register a list of things they want or need for their new home at a local stores. Some common things people will put on a gift registry include kitchen tools like knives and things like curtains. Even if there isn’t a registry, a good housewarming gift is something to decorate the new house with, like a piece of art or a plant.

    3     This is often appreciated since at a housewarming there isn’t a lot of food served. There are usually no planned activities like games at a housewarming party. The host or hostess of the party will, however, probably give all the guests a tour of their new home. Sometimes, because a housewarming party happens shortly after a person moves into their new home, people may be asked to help unpack boxes.     4    

Housewarming parties get their name from the fact that a long time ago people would actually bring firewood to a new home as a gift.     5     Now most homes have central heating and don’t use fires to keep warm.
