完形填空

I have a cousin who’s a farmer. If you saw him on market day with his old boots and worn hat, you might think he was a tramp (流浪汉). But he’s either buying or selling       for thousands of pounds. He doesn’t have a luxurious lifestyle, but the farmhouse, dozens of acres of land, machinery, cattle, chicken and crops must be worth a fortune. You might describe him as a       man, but he doesn’t look like that.
My father owned a shop selling newspapers, cigarettes, birthday cards, toys, books and magazines. The shop       a comfortable life for us, but we weren’t rich. The only luxury was that my father owned a car when most people in our town couldn’t afford one,      professionals such as doctors and lawyers.

Andrew Bruce, the 11th Earl (伯爵) of Elgin,       a group of press people to his luxurious home in Fife, Scotland. His      , the 7th Earl of Elgin was famous for removing and transporting to Britain priceless sculptures from the Parthenon, a very famous temple in Greece. The so-called Elgin Marbles can be seen in the British Museum. The Earl’s castle was       cold, despite a fire burning in the hearth (壁炉). He explained to us,“I’m sorry it’s so cold, but you should know that a gentleman’s house is always cold.”
There you have it:     doesn’t always bring comfort.
