2.In a computer age,a broadband Internet connection is very popular now.Whether cable or mobile broadband,today's connections are many times faster than those in the early days.Videos play smoothly,complex websites load quickly,and files download much faster than ten years ago.And the files are much bigger too.
There's  a catch:You have to live near enough to a major city to get broadband Internet.If you don't,it's slow dial-up access for you.And for those living really far out,there may be no Internet access at all.
Technology experts often talk about the"last mile"problem,which refers to the difficulty of bringing Internet access to remote locations.In cities and suburbs(郊區(qū)),it's relatively easy to provide access for everyone.It is much more difficult to deliver access to those living far from cities,especially in developing countries.Internet service providers,for their part,have been reluctant to provide access to sparsely (稀疏地) populated areas.The handful of Internet users they would reach wouldn't cover the expense.
But every year,technological advancements allow of more and more Internet users.Most broadband connections today run over existing cable TV and telephone lines although these technologies aren't available everywhere.
Some companies have delivered the Internet over standard power lines.Advancements in cheaper,more efficient fiber optics cables (光纖電纜) promise to bring extremely fast Internet connections to more users.Still,the"last mile"problem remains hard to deal with.There will always be somewhere that doesn't have an affordable broadband connection.But someday that might not matter.If the rapid progress in cell phone technology is any indication,it may not be too long before an Internet connection simply follows you wherever you go.

41.The underlined part"a catch"(in Paragraph 2)probably means"D".
A.a(chǎn) big task      B.a(chǎn) wonderful plan
C.a(chǎn) major city    D.a(chǎn) hidden problem
42.Which of the following is TRUE according to the passage?D
A.Internet connections have been popular everywhere.
B.Internet service providers are willing to care about rural(農(nóng)村的)customers.
C.Computer can't become popular in developing countries.
D.The problem of Internet access hasn't been completely dealt with.
43.Paragraph 4mainly tells us that technological advancementsC.
A.make TV and telephone available everywhere
B.bring great change to people's everyday life
C.make it possible for more people to use the Internet
D.bring faster Internet connections to users
44.What may eventually settle the"last mile"problem?D
A.The broadband connection's getting faster.
B.More and more Internet users.
C.More and more Internet connections.
D.The rapid progress in cell phone technology.
45.The best title for this passage may beA.
A.Internet Connection Problems
B.Internet Connections Need Improving
C.Progress in Internet Connections
D.Internet Connections Today.

分析 本文講述當(dāng)代網(wǎng)絡(luò)連接發(fā)展十分迅速,無論是播放或是下載都得到大大提速,然而背后仍然隱藏著"最后一米"的問題即:邊遠地區(qū)網(wǎng)絡(luò)權(quán)限的問題.但手機技術(shù)的迅速發(fā)展使得將來這一問題的解決成為可能.

解答 41-45 DDCDA
41  D  猜測詞義題.由第二段You have to live near enough to a major city to get broadband Internet.可以看出網(wǎng)絡(luò)有個隱藏的問題,那就是你想獲得高速的網(wǎng)絡(luò),你必須住在大城市附近,故選D.
42 D   推理判斷題.由文章第二段experts often talk about the"last mile"problem,which refers to the difficulty of bringingInternet access to remote locations.技術(shù)專家經(jīng)常談?wù)撟詈笠幻椎膯栴},即將網(wǎng)絡(luò)權(quán)限帶給邊遠地區(qū),可知網(wǎng)絡(luò)權(quán)限的問題還未完全解決,故選D.
43  C  細節(jié)理解題.由第四段advancements allow of more and more Internet users技術(shù)進步允許更多的網(wǎng)絡(luò)使用者,可知這一段主要就是講技術(shù)進步使越來越多的人使用網(wǎng)絡(luò),故選C.
44  D  推理判斷題.由文章最后一句the rapid progress in cell phone technology is any indication,it may not be too long before anInternet connection simply follows you wherever you go.如果手機技術(shù)的迅速發(fā)展是一個征兆,無論你去哪里都會有網(wǎng)絡(luò)連接不會太久,可知手機技術(shù)的迅速發(fā)展最終會解決最后一米的問題,故選D.
45   A. 標(biāo)題歸納題.文章主要介紹了在如今的電腦時代,仍然存在網(wǎng)絡(luò)連接不上的問題,作者分析了原因,并給出了可能解決的辦法.故選A.

點評 學(xué)生需要認真閱讀原文,把握文章大意,對文章脈絡(luò)有整體的了解,能仔細查找文中細節(jié),并能根據(jù)文章內(nèi)容進行合理的推測判斷.

10.Lying in the town of Kutná Hora in the Czech Republic,the Sedlec Ossuary(藏骨堂)never fails to inspire fear and fascination in first-time visitors.Usually,an ossuary is just a site where bones are kept,but this one is very different.It is an ossuary richly decorated with bones of mote than 40,000human skeletons(骨架),a strange fact that led to its nickname-the Bone Church.
The current location of the Sedlec Ossuary was originally a cemetery.In 1278,the headmaster of Sedlec paid a visit to the Holy Land,and on his return,he brought back a handful of earth from Golgotha,the area where Jesus is thought to have been crucified(釘在十字架上).The headmaster spread the soil in the cemetery and word went around that the place was blessed.Soon,people from all over Europe wanted to be buried there.In the 15thcentury,the cemetery was nearly out of place,so to make room for newcomers,some of the older bones were removed from the cemetery and stored in an ossuary they built.At the time,however,the bones were merely piled up and not carefully arranged.
It was Frantisek Rint,a wood carver,who rearranged the burial site and transformed it into the magnificent Bone Church.In 1870,he cleaned up thousands of bones and carefully pieced them together in various shapes.The designs include two chalices,several candleholders,a noble family crest,a splendid chandelier,and much more.Equally astonishing are the six bell-shaped pyramids of bones in the four corners of the ossuary.Together,they express the short life of human beings.To this day,tourists can't help but feel small after a visit to the Bone Church.

24.What makes Sedlec Ossuary different?B
A.It has a special nickname.    
B.It is decorated with bones.
C.It keeps bones of common people.
D.It's originated from a cemetery.
25.Why would people like to be buried in Sedlec?D
A.It was well managed.    
B.It was where Jesus was buffed.
C.People saw it as home.
D.People believed it was blessed.
26.Why was an ossuary built in the 15th century?D
A.To reuse the bones.    
B.To sort out the bones.
C.To enlarge the cemetery.
D.To manage space for newcomers.
27.What does Paragraph 3mainly tell us?B
A.We human beings are great.    
B.The church was amazingly decorated.
C.Frantisek Rint is a great carver.
D.The bones in the church are valuable.

17.Dear Mr.King,
I'm Bob Watson,one of the customers in your grocery store.I'm writing to express my idea about your goods.
Your Supermart is outstanding in many ways.First I enjoy the selection of produce and fresh bakery items.Second your low prices and excellent customer service keep me coming back to Supermart.I have found,however,that I must make a separate shopping trip to one of your competitors because there are many items your store does not carry.This becomes inconvenient for me,as my time is valuable,and I don't like to make two trips.I have been a long time Supermart shopper and hope to continue for many years.If I could find all the items I need in one place,I would be a more satisfied customer.
Specifically,I have never been able to purchase nacho cheese soup at your store.I can find other flavors (味道) of soup,but your store does not carry nacho cheese soup,a common ingredient (原料) in many of my recipes.In addition,I can only find large wonton wrappers,while many other stores carry both large and small and offer a more varied selection for their customers.Another example is Regent Brand Chili Seasoning.Though it is not a leading brand,it is still common on the shelves of other grocery stores in this area and is superior in flavor to its competitors.
I sincerely hope to continue a relationship with your store,and I hope that you will consider the possibility of expanding your goods to be more competitive.
Yours truly,
Bob Watson

A.a(chǎn) very picky reporter                   
B.a(chǎn) regular customer of the store

7.Iceland is a large island.In fact,it's the world's 18th  largest island.Most of the population,however,lives in the southern part of the country,in or around the capital city of Reykjavik.By its very name,you'd expect Iceland to be mostly ice.Looking at Iceland on a map,you'll notice it sits just outside the Arctic Circle.Despite this location and its name,Iceland actually has temperate climate because it's warmed by the Gulf Stream.The Gulf Stream also helps keep Iceland's coastal ports ice-free through the winter.
There is plenty of ice on Iceland,though.The country consists of a large plateau(高原)that includes fields of sand,mountains and glaciers(冰川).Over sixty percent of Iceland is tundra(苔原).About fourteen percent of Iceland is lakes and glaciers.Only about twenty-three percent of the country has plants or vegetation of any kind.
Iceland was settled in the late 800s and early 900s by Norsemen from the Scandinavian country of Norway.Other settlers also came from Ireland and Scotland.From the thirteenth century up until 1918,Iceland was part of the Norwegian and later Danish monarchies.For most of that time,the small Icelandic population depended upon fishing and farming to make a living.For hundreds of years,Iceland was one of the poorest and least developed countries in the world.After World War II,international aid and industrialization of the fishing industry turned Iceland into one of the wealthiest countries in the world.In 1914,Iceland became part of the European Economic Area.which allowed its economy to grow even.more.
Iceland is one of the youngest islands in the world.Surtsey rose out of the ocean during a series of volcanic eruptions between 1963and 1968.Today,only scientists who study the growth of new life can visit the volcanic island of Surtsey.

25.What would be the best title for this passage?D
A.An Island of Ice and Snow.
B.A Developing Island in the world.
C.Island,the Largest Island in the World.
D.An Introduction to Iceland.
26.What can you know about Iceland according to the passage?B
A.Its capital city is crowded.
B.Its climate is fairly mild.
C.People live in the east.
D.It's located in the Arctic Circle.
27.What is mainly talked about in Paragraph 3?A
A.Iceland's development    B.Iceland's settlers.
C.Iceland's geography.    D.Iceland's politics.
28What can we infer about Surtsey from the last paragraph?C
A.Science develops fast there        B.Many visitors drop in there.
C.No human beings live there.       D.Its citizens feed on fish.

11.Upon reaching an appropriate age,usually between 18and 21years,children are encouraged,but not forced,to"leave the nest"and begin an independent life.After children leave home they often find social relationships and financial support outside the family.Parents do not arrange marriages for their children,nor do children usually ask permission of their parents to get married,Romantic love is most often the basis for marriage in the United States; young adults meet their future spousesthrough other friends,at jobs,and in organizations and religious institutions,Although children choose their own spouses,they still hope their parents will approve of their choices.
In many families,parents feel that children should make major life decisions by themselves.A parent may try to influence a child to follow a particular profession but the child is free to choose another career.Sometimes children do precisely the opposite of what their parents wish in order to assert their independence.A son may deliberately decide not to go into his father's business because ofa fear that he will lose his autonomy in his father's workplace.This independencefrom parents is not an indication that parents and children do nt love each other.Strong love between parents and children is universal and this is no exception in the American family Coexisting with such love in the American family are cultural values of self-reliance and independence.

12.Up to 90%of school leavers in major Asian cities are suffering from myopia-short-sightedness,a study suggests.Researchers say the"extraordinary rise''in the problem is being caused by students working very hard in school and missing out on outdoor light.
Eye experts say that you are short-sighted if your vision is blurred(模糊的)beyond 2m.It is often caused by an elongation(拉抻)of the eyeball that happens when people are young.According to the research,the problem is being caused by a combination of factors--a commitment to education and lack of outdoor light.
Professor Morgan who led this study argues that many children in South East Asia spend long hours studying at school and doing their homework.This in itself puts pressure on the eyes,but exposure to between two and three hours of daylight helps maintain healthy eyes.
Cultural factors also seem to play a part.Across many parts of South East Asia children often have a lunchtime nap.According to Professor Morgan they are missing out on natural light to prevent short-sightedness.
A big concern is the number of the students suffering from‘‘high"myopia.One in five of these students could experience severe visual impairment(障礙)and even blindness.These people are at considerable risk-sometimes people are not told about it and are just given more powerful glasses-they need to be warned about the risk and given some self-testing measures so they can get to all ophthalmologist and get some help.
For decades,researchers believed there was a strong genetic component to the condition.But this study strongly suggests all alternative view.‘‘Any type of simple genetic explanation just doesn't fit with that speed of change;gene pools just don't change in two generations.Whether it's a purely environmental effect or an environmental effect playing a sensitive genome(基因組),it really doesn't matter.The thing that's changed is not the gene pool-it's the environment."

29.As is mentioned above,which factor mainly results in students'myopia in South East Asia?C
A.Genetic faults of the people.
B.Visual impairment and blindness.
C.The shortage of outdoor light.
D.Lack of research into the problem.
30.Which of the following statements do you think agrees with Professor Morgan?D
A.A lunchtime nap is helpful in reducing myopia.
B.Glasses keep myopia from getting even worse.
C.It's necessary to treat myopia with an operation.
D.It's of vital importance to reduce educational pressure.
31.What's the main idea of the last paragraph?B
A.Gene remains the main cause of the long-standing problem.
B.The environment is to blame for the extraordinary rise in myopia.
C.Short-sightedness has nothing to do with changes in gene pools.
D.An environmental effect playing a sensitive genome counts.
32.What's the best way to take care of your eyes according to the passage?D
A.Equip the classroom with better lights.
B.Look at the Sun from time to time.
C.Do eyes exercise regularly.
D.Spend more time in the open air.
