How the Grand Canyon (大峡谷) was created remains one of the geology’s greatest mysteries. Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years. But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead. Down-cutting is when a flood of water rushes over a landscape (地形) with enough force to cut deeply into the ground and leaves behind a canyon. Such a flood is usually released when a natural or man-made dam (堤坝) bursts.Robert Webb, a research geologist, says natural dams seem to have formed and broken across the Colorado River several times during the last million years. The dams were built when lava(熔岩) from the eruptions of nearby volcanoes flowed into the river. The lava hardened into hard rocks and blocked the river, causing it to back up and form a lake. Each time the lake grew so huge that it broke the rock dam, releasing a flash flood that furthered the down-cutting process and deepened the canyon.Down-cutting is not just an earthly event. Satellite photos sent back from Mars suggest that the process has happened there, too, say many other researchers.The photos, taken by the Mars Global Surveyor, indicate that an enormous lake existed on Mars 3.5 billion years ago. The lake spilled into a large nearby hole. One edge of the hole broke, releasing a flash flood that quickly carved out a grand canyon.The existence of down-cutting on Mars is just one more piece of evidence that the cold, dry planet was once warm and wet.1. In the past, deep canyons were believed to have formed _______.A. as a result of a sudden break of volcanoesB. due to river flows over millions of yearsC. owing to the burst of artificial damsD. thanks to our ancestors’ creative work2. According to the passage, which of the following statements is TURE?A. Several volcanoes broke out on Mars directly creating grand canyons.B. Several great lakes existed on the upper parts of the Colorado River.C. People built high dams on the upper parts of the Colorado River.D. The Colorado River crossed the Grand Canyon to form down-cutting.3. From the last three paragraphs we learn that _______.A. there are great lakes on MarsB. there are active volcanoes on MarsC. there might be cities on MarsD. there might be life on Mars4. The passage can be titled as _______.A. Lakes on Earth and MarsB. The Cause of Lake FormationC. The Force of Dam BreakingD. Canyons—Results of Flood Cutting参考答案1—4、B B D D写人记事（阅读理解）Some years ago,writing in my diary used to be a usual activity.I would return from school and spend the expec ted half hour recording the day’s events,feelings,and impressions in my little blue diary.I did not really need to express my emotions by way of words,but I gained a certain satisfaction from seeing my experiences forever recorded on paper.After all,isn’t accumulating memories a way of preserving the past?When I was thirteen years old,I went on a long journey on foot in a great valley,well-equipped with pens,a diary,and a camera.During the trip,I was busy recording every incident,name and place I came across.I felt proud to be spending my time productively,dutifully preserving for future generations a detailed description of my travels.On my last night there,I wandered out of my tent,diary in hand.The sky was clear and lit by the glare of the moon,and the walls of the valley looked threatening behind their screen of shadows.I automatically took out my pen...At that point,I understood that nothing I wrote could ever match or replace the few seconds I allowed myself to experience the dramatic beauty of the valley.All I remembered of the previous few days were the dull characterizations I had set down in my diary.Now,I only write in my diary when I need to write down a special thought or feeling.I still love to record ideas and quotations that strike me in books,or observations that are particularly meaningful.I take pictures,but not very often—only of objects I find really beautiful.I’m no longer blindly satisfied with having something to remember when I grow old.I realize that life will simply pass me by if I stay behind the camera,busy preserving the present so as to live itin the future.I don’t want to wake up one day and have nothing but a pile of pictures and notes.Maybe I won’t have as many exact representations of people and places; maybe I’ll forget c ertain facts,but at least the experiences will always remain inside me.I don’t live to make memories—I just live,and the memories form themselves.1.Before the age of thirteen,the author regarded keeping a diary as a way of .A.observing her school routineB.expressing her satisfactionC.impressing her classmatesD.preserving her history2.What caused a change in the author’s understanding of keeping a diary?()A.A dull night on the journey.B.The beauty of the great valley.C.A striking quotation from a book.D.Her concerns for future generations.3.What does the author put in her diary now?( )A.Notes and beautiful pictures.B.Special thoughts and feelings.C.Detailed accounts of daily activities.D.Descriptions of unforgettable events.4.The author comes to realize that to live a meaningful life is .A.to experience itB.to live the present in the futureC.to make memoriesD.to give accurate representations of it语篇解读:本文为记叙文。
