Read the passage and fill in the blanks with proper words(在短文的空格内填入适当的词,使其内容通顺,每空格限填一词,首字母已给):

On March 28 Richard’s other workmates were heading back to the main camp on the coast of Antarctica (南极洲), but Richard would have to stay and work at the base camp(探险营地). He stood o1. the small house and shook hands with the men who were leaving.

‘I don’t like leaving you here alone.’ Peter said. ‘I’ll be OK.’ Richard r2.. He was looking forward to the challenge of spending the winter at the base camp. He would record the weather. There was plenty of food and fuel (燃料) in the little house. He felt sure n3. would go wrong.

But something did go wrong. Richard burned the fuel for heat, but the fumes (有毒气体) didn’t leave the house. Slowly he was poisoned (中毒). On May 31 he broke down. When he came to(苏醒), he made h4.into the sleeping bag. Three days later he knew it was Sunday. The men thought of his radio message. Richard moved hard out of bed and made the call. He didn’t want the men to know how sick he was. It was too dangerous for them to come to save him.

By will-power, Richard stayed alive. He was quite weak and was hardly a5.to walk. But he tried to do the basics. He cooked food and had a simple m6.. He took notes of weather and sent radio messages. But by late June, the men guessed that something was wrong. Most of the time, Richard’s messages made no answer.

On August 11 Peter and two others reached the base camp. They hardly recognized (认出) Richard. He was very thin and looked terrible. Richard greeted them and then fell to the ground. The men arrived in time. They saved Richard. After two months of care, he felt b7.. He and his men worked together again.

You're not the same person you were as a child. You're not even the same personyou were five years ago. We don't just mean your personality. While we'd love tostart a never-ending discussion over the “true self”,we're here to talk about thecells(细胞)in your body.

Do you know how your fingernails and hair are constantly growing and replacingthemselves? The same thing happens almost everywhere in your body. Your outerlayer of skin makes way for fresher skin, and inside your veins(血管),blood cells turn over to make wayfor fresh blood. It's probably no surprise that these types of cells are short-lived, even some of the mostseemingly permanent(永久的)parts of your body replace themselves over time-including your bones.

Strong as your bones might seem, the cells they're made of won't last a lifetime. Bones are masters at rebuilding themselves, which is why most broken bones can heal on their own into the right shape.

Bones have special cells called osteoclasts(破骨细胞)whose job is to break down bone, even if itisn't broken, and send the minerals into the blood stream. This may sound frighteningly like your bonesare wearing away, but your body knows what it's doing. As osteoclasts break down bone, osteoblasts(成骨细胞)build up new bone to replace the old. By the end of each year, about 10 percent of yourentire adult skeleton will have been rebuilt through this process.

If 10 percent of your bone breaks down every year, it must take about ten years to renew 100percent of your skeleton. That would be a great guess, and it lines up nicely with the medical myth thatthe human body's cells are fully replaced every seven years, but the body is a bit more complex. That10 percent is just an average-some bone grows faster than that, and some grows slower. While someparts of your bone will turn over quickly, other parts will stick around for decades. In fact, most bonecells could live as long as 50 years.

So before you get wrapped up in an identity crisis(危机)about the cells in your body disappearingon you, know that you can lose some hair and you can cut your nails, but the bones of you aren't goinganywhere-at least not very soon and not all at once.
