       If you have ever been rock climbing, you will know that it is not a very easy sport．In fact, you probably felt quite defeated when you first tried to do any serious climbing． Indoor and outdoor rock climbing are both extremely demanding and require practice to get good at．It is one of the most physically and mentally demanding sports．

       There are three basic types of rock climbing．Top roping is the most common type and the climber need to climb with a partner．The second type, which is very similar to top roping, is called．lead climbing．In both of the types, the climber can sit off the wall and rest on the rope．The third type is called bouldering．Bouldering is a type of free climbing without any ropes．This is the most demanding of all climbing types．The climber must be able to complete the climbing without taking a rest on the rope．

       Believe it or riot, climbing is said to be about 75% legs and only 25% arms．To climb efficiently and successfully, a person needs to have a wonderful technique. One of the major rules of rock climbing is to always have three points touching the wall, whether it is both feet and one hand, or one foot and both hands, as it is much easier to have your weight rest on three points than on two． Another important idea to grasp is that your arms in most cases will do the climbing; they only hold you into the wall so that your legs are actually pushing you upward．Also, the closer you are to the wall, the easier it is to climb．

       Rock climbing may sound a bit too extreme for the everyday person, but it is really an amazing workout．Once you get into the sport, and learn how to position your body and rest your weight, then you can begin to deal with some difficult problems．The great thing about rock climbing is that it is mentally challenging as well．You are constantly analyzing the way your body moves and how to do certain moves on the wall． For anyone who wants to get into shape, rock climbing is a fun and effective way to exercise muscles．

       The sun is setting on a summer night． At the entrance to a deep, dark cave, a few bats fly out and begin swirling high up into the air．More and more of the small, furry creatures appear．Within a few minutes, a whole river of bats is pouring out of the cave, and they keep coming, millions and millions of them．

       Sound like a scary horror movie? Believe it or not, this scene takes place every night, all summer long, at Bracken Cave in Texas, where 20 million bats fly outside to feed on insects．"It is magical," says Jim Kennedy of Bat Conservation International in Austin Texas．"It is one of the most majestic（壯麗的）  animal movements on the planet．"

       Every March or April, Mexican Free-tailed bats migrate up to 1,000 miles （1609 kilometers） from their winter home in Mexico to this cave, where they raise their young．Soon after they arrive, each mother gives birth to one pup．As many as 500 baby bats live crammed into one square foot （30．48 cubic centimeters）of space, and all those bodies create nice warm temperatures to keep them cozy and comfortable．If you've ever lost sight of your parents on a crowded playground, you may be wondering how mother bats recognize their children．They use their sense of smell to tell which pup is theirs when it is．time for the babies to nurse．

       The cave, a quiet place in winter, is full with life all summer-and not just with bat residents．Bat waste soon covers the floor, providing food for tiny organisms（生物體） like bacteria and fungi（真菌類(lèi)）．And then there are the bugs．

       When the adult bats leave the cave at night to feed, they are helping humans．They eat tons of insects in a single night, including many pests that eat farmer's crops． And they get rid of mosquitoes, too．

　 Imagine an eco-conscious city where rooftops have been transformed into fertile, green gardens． It's a place where every home is equipped with a system that recycles valuable water resources． In this town, protecting the planet is a way of life．That's how Abby Sharp, 14, Wyatt Peery, 13, and Tom Krajnak, 14, saw their city of tomorrow．The vision won the eighth-graders from Bexley, Ohio: first prize at the 2009 National Engineers Week Future City Competition．

　 The annual design competition challenges middle school students to use engineering to deal with issues that affect the earth． This year the- competition focused on water conservation．Participants had to come up with ways to improve water use in the home．Kids from 38 middle schools across the country competed in the finals．'The event took place from February 17-18 in Washington, D．C．More than 30,000 students entered the competition．

　　　 Abby, Wyatt and Tom call their winning city Novo Mondum．The name means “new world” in Latin．Novo Mondum sits on the coast of Iceland．The group chose the spot for its wealth of clean energy resources, such as geothermal（地?zé)岬模〆nergy and hydropower．Both sources use the power of nature to generate electricity. Geothermal energy draws heat from deep inside the Earth．Hydropower gets energy from flowing water．"Our city is very globally aware," Abby told TFK．

　　　 Students team up with a teacher and a volunteer engineer mentor（顧問(wèn)） to develop their cities．Each group creates a fictional city on SimCity 4 Deluxe, a computer game that allows players to build virtual towns．Then they construct tabletop models of the cities and write essays describing their project, The models must be made using recycled materials and cost no more than $100 to build．

Are Baiji Dolphin Extinct?

       Does the Yangtze River still have baiji the graceful, grey dolphin with tiny eyes and a long narrow beak?

    Since November 6, a team of scientists from China, Switzerland, the United Kingdom, the United States, Germany and Japan have been searching for any sign of the freshwater dolphin on the middle and lower sections of the river．After six weeks, they came back empty-handed．

    Wang Ding, of the Chinese Academy of Sciences, who is the head of the team, said．he has seen a sharp decline in the baiji population over the past few decades． However, he is still unwilling to call the species extinct, and adds, "We will try every effort to save them as long as they are not found to be extinct．"

    The baiji is shy and nearly blind and is, one of the world's oldest．'dolphin species． It dates back some 20 million years and is found only in the Yangtze．It's listed as one of the  12 most endangered animal species in the world．

       Around 400 baiji were believed to be living in the Yangtze until the 1980s．A 1997 survey spotted 13．Two years later their numbers were down to two．

    The rapid disappearance of this dolphin over the past two decades coincided with（與……同時(shí)）the rapid expansion of economic development along the river． Research on some dead baiji collected in recent years showed that more than 90 percent of the deaths were caused by human activities．

   One reason is that over-fishing has cut the dolphin's food sources．Dams built along the river and neighboring waterways have also kept them from swimming into and out of their habitats． Meanwhile, waste discharge（排放） has seriously polluted the river． And heavy river traffic has greatly reduced their living space．

    The disappearance of the baiji would be the first instance of a large aquatic mammal（水生哺乳動(dòng)物）being driven to extinction since hunting killed off the monk seal（僧海豹）around                                                                      1952．

       A．love of baiji                                                B．eagerness to write the passage

       C．a(chǎn)nger for not having a baiji                           D． dissatisfaction with our government

Some years ago when l was in my first year in college, I heard Salome Bey sing for the first time．The moment was exciting, Salome's 36 filled the room and brought the．theater to life．I was so 37 that I decided to write an article about her．

　　　 I 38 Salome Bey, telling her I was from Essence magazine, and that I wanted．to meet her to talk about her career． She 　39　 and told me to come to her studio next Tuesday．When I hung up, I was scared out of my mind．I 40 I was lying．I was not a writer at all and hadn't even written a grocery list．

　　　 I interviewed Salome Bey the next Tuesday． I sat there 41 , taking notes and asking questions that all began with, "Can you tell me…" I soon realized that 42 Salome Bey was one thing, but writing a story for a national magazine was just impossible．The 43 Was almost unbearable． I struggled for days 44 draft after draft. Finally I put my manuscript（手稿） into a large envelope and dropped it into a mailbox．

　　　 It didn't take long． My manuscript 45 ．How stupid of me! I thought．How could I 46 in a world of professional writers? Knowing I couldn't 47 the rejection letter, I threw the unopened envelope into a drawer．

　　　 Five years later, I was moving to California．While 48 my apartment, I came across the unopened envelope． This time I opened it and read the editor's letter in 　49 ;

Ms Profit,

　　　 Your story on Salome Bey is fantastic． Yet we need some 50 materials．Please add those and return the article immediately; We would like to 51 your story soon.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Shocked, it took． me a long time to 52　 ．Fear of rejection cost me dearly． I lost at least five hundred dollars and having my article appear in a major magazine． More importantly, I lost years of 　53 writing．Today, I have become a full－time writer, Looking, back on this 54 ,I learned a very important lesson: You can't 55 to doubt yourself．
