 But 34-year-old US explorer Colin O' Brady is different. Three {#blank#}3{#/blank#} (month) ago, he became the first person {#blank#}4{#/blank#} (cross) Antarctica alone. During the 932-mile journey, O' Brady spent 54 days in extreme conditions. He had to push {#blank#}5{#/blank#} (he) to the limit. He carried everything he'd need on a sled. But even with enough food, O' Brady began to become {#blank#}6{#/blank#} (thin) and weaker after six weeks. "I {#blank#}7{#/blank#} (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.

But on Christmas Day, O'Brady decided to make {#blank#}9{#/blank#} final effort without stopping for a rest. Luckily for him he made it, getting to the finish line earlier than Louis.

Then she asked me {#blank#}5{#/blank#} the restaurant was on the fifth floor, I told her I was going to the restaurant {#blank#}6{#/blank#} (my), and I offered to show her where it was. She said, "Oh, fine." Then she said, "Why don't we have lunch together?" Imagine! I never thought I would have lunch with a movie star! But I {#blank#}7{#/blank#} (do)! We had lunch together and talked for about half {#blank#}8{#/blank#} hour. She even paid for my lunch! Can you imagine? But that isn't all. {#blank#}9{#/blank#} lunch, she asked me if she could give me a ride to somewhere. I told her I was going home. {#blank#}10{#/blank#} she took me home in her big, black limousine (豪华轿车). It was an exciting day. That's all for now. I've got to run!
