The race is so dangerous that you have to sign a form to say where you want your body to be sent in case you die. I tried to persuade her, saying, “The worst that may happen is that I get a bit sunburned (晒黑的)”When I arrived in Morocco, I discovered the desert. It was so wonderful. I was bewitched. However, things went wrong on the fourth day. When we set out that morning, there was already quite a bit of wind. Suddenly, a very strong sandstorm began. I was blinded and I couldnt breathe. I understood for the first time how powerful a sandstorm could be. I had to keep moving to keep myself from getting buried. Finally, I arrived at a safer place, waiting for the storm to end.It lasted for eight hours. When the wind died down, it was dark. So I slept on the dunes (沙丘). What I couldnt have imagined was how greatly that storm would change everything around me. I woke up very early the next day. I had a compass (指南针) and a map, so I thought I could find my way back perfectly well. I wasnt worried because I was sure that sooner or later I would meet someone. That was my plan, but unfortunately it didnt work out.After running for about four hours, I climbed up a dune and still couldnt see anything. Thats when I knew I had a big problem. When I realized I was lost, the first thing I did was to urinate (小便) in my spare water bottle. I remembered my grandfather telling me how, during the war, he and his soldiers had drunk their own urine when their water ran out. I wasnt worried because I was sure the organizers would find me soon. As I expected, they found me at last.【文章大意】作者讲述了自己1994年参加撒哈拉沙漠马拉松时遇见沙尘暴的情景。5What did the authors wife think of his plan?AIt was meaningless.BIt was very interesting.CIt was likely to be successful.DIt was very surprising.解析：D推理判断题。根据第一段的.thought I was crazy.

Scientists believe, historically, humans have relied on the movement of the sun across the sky to track time. The ancient Egyptians built tall obelisks (方尖碑) that would cast shadows to help divide the day into sections. These obelisks worked in much the same way as sundials (日晷), which were a popular means of timekeeping long ago. Of course, sundials didnt help much at night or on cloudy days. To help keep time when it wasnt sunny, ancient people also learned to track the movement of the planets and constellations (星座) after dark.Other devices were developed over time, including hourglasses and water clocks. These devices relied upon the time it would take a particular substance (物质), such as sand or water, to move from one part of a container to another. Rather than clocks, though, these devices were more like timers.How did people long ago set up a meeting at a certain time in the future? Some historians believe many people relied upon a technique as simple as pointing to an area of the sky. When the sun reached that point, that was when they would meet the next day.Of course, humans, being the clever creatures we are, relied upon a variety of natural solutions to the problem of timekeeping. For example, many people simply trained their bodies to wake up at the first light of dawn. Others may have relied upon animals, such as roosters, as alarm clocks. If people had to be up before dawn, they might have relied upon the full bladder method. They could wake up in the middle of the night to go to the bathroom.【文章大意】本文为说明文，话题是社会文化类。文章介绍了钟表问世之前人们记录时间的方式。9What do the examples suggest in Paragraph 1?ATall obelisks looked like sundials.BObelisks could be used on cloudy days.CIt was hard for ancient people to keep time.DThe ancients tracked time by the natural world.解析：D推理判断题。根据第一段的.humans have relied on the movement of the sun across the sky to track time.ancient people also learned to track the movement of the planets and constellations after dark可知，古代人类利用自然现象来记录时间。10How did people fix a time for their meeting during the day?ABy the calls of animals.BBy the position of the san.CBy the planets and constellations.DBy the movement of sand or water.解析：B细节理解题。根据第三段的最后两句可知，太阳的位置对他们确定聚会的时间具有帮助作用。11What might ancient people do to wake up before dawn?APredict the first light of dawn.BFind special natural solutions.CDrink water before going to bed.DTrain roosters to be alarm clocks.解析：C推理判断题。根据最后一段的They could wake up in the middle of the night to go to the bathroom可知，古人睡觉前喝很多水然后会在半夜起来上厕所，这样天不亮就可以起来了。12What is the best title of the text?AWhen did clocks appear?BWhy is the sun important?CWhere did clocks come from?DHow did people keep time before clocks?解析：D主旨大意题。本文主要介绍了钟表问世以前人们记录时间的各种方法。.七选五What should you do if you find that you do not have enough time to get all your homework done?
