            • 1． We talk about people being"color-blind"but very few of us are．Even those who describe  themselves as color-blind are normally just color lack．A strongly color-blind person will still be able to tell 20different colors，compared to the 100or so that normal-sighted people see．
              Pingelap，a tiny island in the Pacific，is a beautiful spot but one that has a genetic trouble．It is known as Color Blind Island because so many people who live on this remote island can only see in black and white．
              Not being able to see in color is bad enough．But one islander，Herrol，who's a fisherman，also struggles in full sunlight because all he sees is a painful burnt-out image．"I find it difficult to go outside in the sun，"he says，"because when it's sunny I cannot see to do my work．"
              But if being truly color-blind is rare，why is it that around 10% of the population of Pingelap lire in a totally black and white world？
              Well，we know that in 1780the population of Pingelap was all but wiped out by a tsunami．As few as 20people survived，one of whom was the king．It's believed he had a genetic fault that causes color-blindness and he passed this fault on to his many generations．
              There is one advantage．Herrol can see well，really well，in the dark．So when it gets dark，Herro1and his friends get in their boats and hunt flying fish．They hang up flaming torches and the fish are attracted to the flames．"This type of fishing is fun，"Herrol says，"especially if we catch plenty．So even though it's hard work we enjoy it．"
              5．What is Pingelap famous as？    
              A．A tiny island．                   
              B．A color-blind island
              C．A mentally troubled island．        
              D．A beautiful island．
              6．What can we infer about Herrol？    
              A．He may stay at home when it's sunny．
              B．He is interested in burnt-out images．
              C．He likes taking photos very much．
              D．He doesn't live in Pingelap any more．
              7．What would be the best title for the text？    
              A．The history of Pingelap

            • 2． Malls are popular places for Americans to go to．Some people spend so much time at malls that they are called mall rats．Mall rats shop until they visit hundreds of stores．
              People like malls for many reasons．They feel safe because malls have police stations．Parking is usually free．And the weather inside is always fine．The newest malls have beautiful rest places with waterfalls and large green trees．
              The Mall of America in Minnesota is one of the most popular ones．It covers 4.2million square feet．It has 350stores，eight nightclubs，and a large park!There are parking spaces for 12，750cars．About 750，000people shop there every week．
              The first indoor mall in the United States was built in 1965in Edina Minnesota．People love doing all their shopping in one place．More malls are built around the country．Now malls are town centers where people come to do many things．They shop，and of course，they also eat in food courts that have food from all over the world．They see films at theaters．Some people even get their exercise by doing the new sport of"mall walking"．Others go to malls to meet friends．
              In some malls，people can see a doctor and even go to church．In other words，people can do almost everything in malls．Now people can live in their favorite shopping centers in fact．

            • 3． Machu Picchu is an unusual site in Peru and one of the most mysterious wonders of the world．Built at almost 10，000feet on the top of an Andean mountain，the Incas built hundreds of structures made of stone．A large number of Machu Picchu's surrounding structures date back to the early 13th century，but it was considered a chief sacred site far before then．The Inca people changed the large site into a very small but wonderful city，completely self-sufficient and hidden from below．Agricultural terraces （梯田） surrounded the entire city，fed by natural spring water，supporting the entire population．
              Inca Trail
              The trail is one of the most famous in the world and regarded as one of the best．It covers only 26miles，combining cloud forest，green mountain scenery，forest，and plenty of tunnels，paving stones，and ruins．The four-day hike begins slowly but quickly changes into a difficult journey suitable for those in excellent shape．The trail winds through the Andes，leading alongside and through ruins．Though independent hiking was once permitted，now it must be done with a guide．
              Funerary Rock
              It is believed that the Funerary Rock at Machu Picchu was used as a place to prepare Inca nobles for preservation，or mummifying （做成木乃伊），a common habit among the tribe．Nobles would be laid out to be mummified by the hot sun and freezing cold nights after their organs were removed．The rock is also famous as a spot from which a view of the city is afforded．
              Temple of the Sun
              Within the city's castle，deep within Machu Picchu，is the Temple of the Sun，accessed only by the Emperor and Inca priests．It means the Inca's advanced knowledge of religion，weather，and nature，showing the great extent Incas went to adapt to and learn about nature．Still unbroken，the temple was built to honor the god Inti，who is exactly the sun．The temple was effectively protected．It was also a very important scientific center，built in half-moon shape with openings facing north and east．The windows'shadows in the center of the temple helped see the start of winter solstice （至日），showing farming season．
              33．What do we know about the Inca Trail？    
              A．The scene is very beautiful along the trail．

              D．The trail covers a distance of 80miles in all．

            • 4． The Pacific island nation of Nauru used to be a beautiful place．Now it is an ecological disaster area．Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes．
              For thousands of years，Polynesian people lived in the remote island of Nauru，far from western civilization．The first European to arrive was John Fearn in 1798．He was the British captain of the Hunter，a whaling ship．He called the island Pleasant Island．
              However，because it was very remote，Nauru had little communication with Europeans at first．The whaling ships and other traders began to visit，bringing guns and alcohol．These elements destroyed the social balance of the twelve family groups on the island．A ten-year civil war started，which reduced the population from 1，400to 900．
              Nauru's real troubles began in 1899when a British mining company discovered phosphate（磷酸盐）on the island．In fact，it found that the island of Nauru was nearly all phosphate，which was a very important fertilizer for farming．The company began mining the phosphate．
              A phosphate mine is not a hole in the ground； it is a strip mine．When a company strip-mines，it Comremoves the top layer of soil．Then it takes away the material it wants．Strip mining totally destroys the land．Gradually，the lovely island of Nauru started to look like the moon．
              In 1968，Nauru became one of the richest countries in the world．Every year the government received millions and millions of dollars for its phosphate．
              Unfortunately，the leaders invested the money unwisely and lost millions of dollars．In addition，they used millions more dollars for personal expenses．Soon people realized that they had a terrible problem-their phosphate was running out．Ninety percent of their island was destroyed and they had nothing．By 2000，Nauru was financially ruined．Experts say that it would take approximately$433，600，000and more than 20years to repair the island．This will probably never happen．

              32．What was Nauru like before the Europeans came？    
              A．rich and powerful        B．modern and open
              C．peaceful and attractive  D．greedy and aggressive
              33．The ecological disaster in Nauru resulted from    ．
              A．soil pollution    B．phosphate overmining
              C．farming activity  D．whale hunting
              34．Which of the following was a cause of Nauru's financial problem？    
              A．Its leaders misused the money．       B．It spent too much repairing the island．
              C．Its phosphate mining cost much money．D．It lost millions of dollars in the civil war．
              35．What can we learn about Nauru from the last paragraph？    
              A．The leaders will take the experts'words seriously．
              B．The phosphate mines were destroyed．
              C．The island was abandoned by the Nauruans．
              D．The ecological damage is difficult to repair．

            • 6． Laptop computers are popular all over the world．People use them on trains and airplanes，in airports and hotels．These laptops connect people to their workplace．In the United States today，laptops also connect students to their classrooms．
              Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want．Within five years，each of the 1500students at the college will receive a laptop．The laptops are part of a＄10million computer program at Westlake，a 110-year-old college．The students with laptops will also have access to the Internet．In addition，they will be able to use e-mail to speakwith their teachers，their classmates，and their families．However，the most important part of the laptop program is that students will be able to use computers without going to computer labs．They can work with it at home，in a fast-food restaurant or under the trees-anywhere at all!
              Because of the many changes in computer technology，laptop use in higher education，such as colleges and universities，is workable．As laptops become more powerful，they become more similar to desktop computers．In addition，the portable computers can connect students to not only the Internet，but also libraries and other resources．State higher-education officials are studying？how laptops can help students．State officials are also testing laptop programs at other universities，too．
              At Westlake College，more than 60percent of the staff use computers．The laptops will allow all teachers to use computers in their lessons．As one Westlake teacher said，"Here we are in the middle of Virginia and we're giving students a window on the world．They can see everything and do everything．"

              46．The main purpose of the laptop program is to give each student a laptop to    ．

            • 7． The Republic of Vanuatu is an island nation located in the South Pacific Ocean．It was one of the poorest nations in the region．Within the last five years，however，it has become a hot spot for adventure travelers．In 2006 it was voted the happiest place on Earth．The reason is not that Vanuatu are the richest but that Vanuatu has white-sand islands，clear waters，the world's most accessible live volcano，great diving and food that grows faster than it can be picked．
              With a population of about 221，000，Vanuatu has 113 languages，which is a result of 3，000 years of immigration from many Pacific countries．There are three official languages：English，French，and Bislama．Bislama developed from South Pacific English，a simplified language that traders and other foreigners used it to communicate with speakers of the many local languages．
              Most of the islands are mountainous and of volcanic origin．There are several active volcanoes in Vanuatu，including Yasur on the island of Tanna，one of the world's most accessible volcanoes．If you've ever fancied getting close to a volcano，here's your chance．
              Vanuatu Post's Underwater Post Office has quickly become one of the busiest post offices for postcards in the world!Visitors from around the world want to experience the world's first underwater post office．The Post Office is only 50 meters offshore and at just three meters below the surface，very appealing to the young and young at heart．Since opening in 2003，the underwater post office has received about 100，000 visitors．They have posted one of the waterproof（防水的）postcards available in Vanuatu； these cards are collected regularly by one of Vanuatu Post's four trained divers．The underwater branch is manned daily for usually about an hour，longer with demand．

            • 8． Every culture has it own ways to show friendship．On the island of Hawaii，friendship is part of the"aloha spirit"．In the language of the Hawaiians who first settled the islands long ago，aloha had a very special meaning．That is"to be with happiness"．
              Hawaiians believe that once somebody loves the land，they are ready to love their people or community．This is the second most important thing of friendship．It is called lokahi in the Hawaiian language，which means"oneness with all people"．To enjoy the land you should not be selfish．The land is for everyone who lives on．Today many different people call Hawaii their home．Indeed，Hawaii is a place where people make one big community from many smaller communities．Each person gives kokua（help） to other people so that all feel stronger．It is believed that the islands can be a paradise（天堂） when people live in peace．People are told that their actions should be as gentle as the wind that blows from the sea．When problems happen，people are asked to solve them with understanding．So when people of Hawaii talk about ohana（family），they are really talking about all those who live on the island．
              Living in peace，Hawaiians have developed a third sign of friendship．This personal friendship is shown by giving leis to one another．The lei，a string of flowers，is put over a friend's neck．Then the friend is given a kiss on the cheek．Visitors to the islands are also given leis．When they hear aloha，visitors began to feel at home．Aloha also means"goodbye"，so visitors will hear it again when they leave．It can mean"our hearts singing together"．Perhaps this is how most visitors will remember their new friendship．
              51．Which of the following can be the proper title for this text？    
              A．People in Hawaii                          
              B．Visitors to Hawaii
              C．Traveling in Hawaii                    
              D．Friendship in Hawaii

              A．Happiness matters most for Hawaiians．
              B．Friendship is always together with happiness．
              C．Friendship is every thing in Hawaiian culture．
              D．Friendship has special meanings for Hawaiians．

            • 9． In Singapore，most of us love window-shopping while some others enjoy having a picnic at East Coast Park or Changi Beach on sunny days．Singaporeans are never bothered by the occasional thunderstorm．However，we know that if it rains for long continuous periods，there will be more serious effects．Just recently the main shopping street of Orchard Road was flooded and some part of Bukit Timah was impassable to traffic．People reacted by writing in to the newspaper to complain about this!We forget that other countries suffer much worse effects．Elsewhere，heavy tropical（热带的）storms often result in floods that ruin erops especially in Thailand and Malaysia．This in turn usually means that the price of rice and vegetables here in Singapore will rise because we import these products from them．If there is a typhoon or tsunami，thousands of lives are lost too．This happened in Indonesia and Phuket in Thailand in 2004 and it serves to remind us of how Mother Nature can cause great damage．
              Weather patterns in general have changed dramatically in recent years．Scientists believe that global warming and the resulting melting of the polar ice-cap has caused the level of the ocean to rise．This in turn causes flooding of low-lying areas in countries where the land is rather flat and some parts of which is below water level．It is believed that human activities have caused Mother Nature to show her extreme anger，so it is now important that we really work together to cut down on harmful activities，for example，illegal logging（伐木）or irresponsible forest-burning to clear land for farming．
              56．From Paragraph 1，we can see that most Singaporeans love    ．
              A．making complaints       
              B．going out for picnics
              C．doing window-shopping   
              D．traveling along the coast
              57．What will happen in Singapore if there are floods in its neighboring countries？    
              A．Heavy tropical storms will follow shortly．
              B．The price of rice and vegetables will go up．
              C．Many people will write in to the newspaper．
              D．More rice and vegetables will be imported．
              58．The underlined word"it"in Paragraph 2 refers to    ．
              A．the arrival of heavy tropical storms
              B．the import of rice and vegetables
              C．the rising price of rice and vegetables
              D．the loss of lives in natural disasters
              59．Which of the following shows how the low-lying areas are flooded？    
              a．global warming
              b．the rise in ocean level
              c．harmful human activities
              d．the flooding of low-lying areas
              e．the melting of the polar ice-cap
              A．c→a→e→b→d       
              B．a→c→e→b→d       
              C．c→a→b→e→d       
              D．d→a→c→b→e
              60．What should we do in order not to make Mother Nature angry？
