14.In the computer age,most of us take a broadband(寬帶)Internet connection for granted.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(檔案文件)download much faster than ten years ago.And the files are much bigger too.
There's a catch,of course: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 (跡象),it may not be too long before an Internet connection simply follows you wherever you go.
68.The underlined part"a catch"(in Paragraph 2)probably means"D".
A.a(chǎn) rare challenge                 B.a(chǎn) desirable plan
C.a(chǎn)n efficient device              D.a(chǎn) hidden problem
69.What can we know from the third paragraph?D
A.Internet connection has not been popular in most cities.
B.Internet service providers care about rural(農(nóng)村的)customers.
C.Computer is popular in developing countries.
D.It is hard to bring Internet access to users in remote areas.
70.Paragraph 4 mainly 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
71.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.

4.Joan,super visor (檢查員) of the town's morals recently accused George,a local man,of having a drinking problem because she noticed his car outside the town's only bar.She reasoned,it was a logical assumption (邏輯假設(shè)).George stared at her for a moment and said nothing.Later that evening,he parked his car in front of her house and left it there all night.
Why is it that so many of our logical assumptions are just plain wrong?And why do we want to act as if they must be true?In an age long before the Internet,a young American at a party found himself seated next to the famous Chinese diplomat Wellington Koo.Completely not knowing what to say to someone from such a different culture,this young man turned and asked,"Likee soupee?"After all,he assumed,don't all Chinese speak in broken English?Mr.Koo smiled and nodded.Later when called upon to speak,Wellington Koo delivered a wonderful talk in fluent English,sat down while the applause was still continuing,turned to the young man and whispered,"Likee speechee?"
Do you know why red roses are so popular?Men keep buying them.They assume that all women prefer red roses.But when women are asked what color of rose is their favorite,they are more likely to answer that they prefer yellow,white or peach.And when asked what kind of flowers they would prefer to receive,the answer is generally not roses at all.The age-old assumption that most women like red roses best is simply not true.
We all make assumptions.They're too often wrong and can easily get us into trouble.So here is what I've learned:when in doubt,check it out.And if I'm not in doubt,I still check it out.We may think we know.But what we know may not be so.So it's best to check it out.
64.According to the passage,we can know George isA
A.clever           B.honest        C.kind-hearted        D.bad-tempered
65.Wellington Koo's experience is mentioned to showB.
A.his talent in speaking English       
B.people's assumption can be false
C.the Chinese were looked down on      
D.his humor in doing with difficult situations
66.Red roses are so popular at the market in thatD.
A.women prefer red roses.                               
B.women like the red color best.
C.they smell pleasant than others.                      
D.men think women would like them.
67.How is this passage mainly developed?A
A.By giving examples.                  B.By presenting research results.
C.By analyzing causes.                 D.By making comparisons.

6.Every people has its own way of saying things,its own special expressions.Many everyday American expressions are based on colors.
Red is a hot color.Americans often use it to express heat.They may say they are red hot about something unfair.When they are red hot they are very angry about something.The small hot tasting peppers found in many Mexican foods are called red hots for their color and their fiery taste.Fast loud music is popular with many people.They may say the music is red hot,especially the kind called Dixieland jazz.
Pink is a lighter kind of red.People sometimes say they are in the pink when they are in good health.The expression was first used in America at the beginning of the twentieth century.It probably comes from the fact that many babies are born with a nice pink color that shows that they are in good health.
The color green is natural for trees and grass.But it is an unnatural color for humans.A person who has a sick feeling stomach may say she feels a little green.A passenger on a boat who is feeling very sick from high waves may look very green.
Sometimes a person may be upset because he does not have something as nice as a friend has,like a fast new car.That person may say he is green with envy.Some people are green with envy because a friend has more dollars or greenbacks.Dollars are called greenbacks because that is the color of the back side of the paper money.
The color black is used often in expressions.People describe a day in which everything goes wrong as a black day.The date of a major tragedy is remembered as a black day.A blacklist is illegal now.But at one time,some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.
In some cases,colors describe a situation.A brown out is an expression for a reduction in electric power.Brown outs happen when there is too much demand for electricity.The electric system is unable to offer all the power needed in an area.Black outs are common during World War two.Officials would order all lights in a city turned off to make it difficult for enemy planes to find a target in the dark of night.

61.Americans use"red hot"to describe the following EXCEPTA.
A.something unfair    
B.small hot-tasting peppers
C.the person who is very angry   
D.popular music like Dixieland jazz
62.People use"in the pink"to express they are in good health becauseD.
A.the expression has a very long history   
B.the color pink makes people feel happy
C.people think the color pink is gentler than red 
D.healthy babies are born with nice pink skin
63.When we say someone feels a little green,it means he/sheC.
A.enjoys himself in boating   
B.is hit by a high wave
C.has a stomach ache   
D.likes trees and grass
64.In the writer's eyes,what is related to a black day?C
A.Being sent a beautiful gift   
B.Passing a very difficult test
C.Being refused during an important interview   
D.Being invited to an exciting party
65.The writer wants to tell usBin American everyday expressions
A.the most popular colors               
B.different meanings of colors
C.how to use colors correctly            
D.why Americans like to use colors.
