6．Now Hear This
What do former American president Bill Clinton and rock musician Pete Townshend have in common．'？Both men have hearing damage from exposure to loud music，and both now wear hearing aids as a consequence．As a teenager，Clinton played saxophone in a band．Townshend，who has the more severe hearing loss，was a guitarist for a band called the Who．He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music．
Temporary hearing loss can happen after only 15minutes of listening to loud music．One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones．One later is that an unusual sound or a ringing is sometimes produced in your head after the concert．
"What happens is that the hair cells in the inner ear are damaged，but they're not dead，"says physician and ear specialist Dr．Sam Levine．According to Dr．Levine，if you avoid further exposure to loud noise，it's possible to   recondition  the cells somewhat．However，he adds，"Eventually，over a long period of time，hair cells are permanently damaged．"And this is no small problem．
What sound level is dangerous？According to Dr．Levine，regular exposure to noise above 85decibels （分貝） is considered dangerous．The chart below offers a comparison of decibel levels to certain sounds．Here's another measurement you can use．If you're at a rock concert and the music is so loud that you have to shout to make yourself heard，you're at risk for hearing loss．That's when wearing protective devices such as earplugs becomes critical．
The facts are pretty frightening．But are rock bands turning down the volume．'？Most aren't．"Rock music is supposed to be loud，"says drummer Andrew Sather．"I wouldn't have it any other way．And neither would the real fans of rock．"
Continued exposure to loud music and the failure to wear earplugs can lead to deafness，according to Dr．Levine．He states，"There's no cure for hearing loss．Your ears are trying to tell you something．That ringing is the scream of your hair cells dying．Each time that happens，more and more damage is done．"
Levels of Common Noises
Normal conversation                            50-65dB
Food blender                                  88dB
Jet plane flying above a person standing outside      103dB
Rock band during a concert                      110-140dB
63．From Paragraph 1，we can learn thatA．
A．loud music is a major cause of hearing loss
B．famous people tend to have hearing problems
C．teenagers should stay away from school bands
D．the problem of hearing damage is widely known
64．In Paragraph 3，the underlined word"recondition"meansD．
A．not to be seen                      B．to fill with sound
C．to become larger in size            D．to make good again
65．The purpose of the chart at the end of the article is to showB．
A．a(chǎn) list of harmful sounds
B．the effect of rock concerts
C．the noise levels of familiar sounds
D．relationship between daily activities and hearing loss
66．Which of the following statements will Dr．Sam Levine probably agree？C
A．When your ears feel warm，your hair cells are dead．
B．Drummer Andrew Sather gives good advice．
C．Many are taking the risk of losing hearing．
D．Doctors know how to cure hearing loss．

4．On an ordinary weekday evening，Jane was at home as usual．As she was considering what she was going to do with her dinner plans for the evening，she was unexpectedly interrupted by an urgent call from her sister"get over here!"

5．Attention to detail is something everyone can and should do-especially in tight job market．
Bob Crossley，a human-resources expert notices this in the job applications that come across his desk every day．"It's amazing how many candidates eliminate （淘汰） themselves，"he says．"Resumes （簡歷） arrive with faults．Some candidates don't bother to spell the company's name correctly．Once I see a mistake，I refuse the candidates，"Crossley concludes，"If they cannot take care of these details，why should we trust them with a job？"
Can we pay too much attention to details？Absolutely not．
Perfectionists（完美主義者） struggle over little things instead of something larger they work toward．"To keep from losing the forest for the trees，"says Charles Garfield，the professor at the University of California，San Francisco，"We must constantly ask ourselves how the details we're working will influence the larger picture．If they don't，we should drop them and move to something else．"
Garfield compares this process to his work as a computer scientist at NASA．"The Apollo II moon launch was slightly off-course 90percent of the time，"says Garfield．"But a successful landing was still likely because we knew the exact position of our goal．This allowed us to make adjustments as necessary．"Knowing where to go helps us judge the importance of every task we undertake．
Again and again，we see that by doing little things within our grasp well，large rewards follow．
67．According to the passage，some job applicants were refused because they areB．
A．too limitedly educated to write a perfect resume
B．so careless that they make some spelling mistakes in their resume
C．so careless that they forget the company's name
D．too foolish to spell the company's name correctly
68．From the passage，we can infer that a perfectionist willD．
A．change their goals as the situations change
B．lose their jobs by paying too much attention to details
C．pay attention to details as much as to their major goals
D．pay attention to details more than their major goals
69．Garfield makes his opinion believable byC．
A．giving ideas of experts              B．offering examples of resumes
C．providing an example of his work．D．showing the results of experiments
70．Which of the following best shows the structure of the passage？A

18．The Cunning Cat and His Company

Everyone was glad to go．Next Monday at 5o'clock in the afternoon，the Cat's neighbors began arriving．（62）By half past five the room was full（63）wherethere were all sorts of birds，sparrows，swallows，woodpeckers and （64）other small animals．

17．A Myth
It is true that world population is growing，but this is not the cause of our current and future global problems．Believing this will cause us to ignore the real problem and risk long-term damage to our planet．
Let me start by explaining why overpopulation is a myth．For one thing，the UN Population Division regularly predicts population growth but provides a low variant  （變量），medium variant，and high variant to factor in various possibilities．In the 2010revision，their high variant suggests that the world population will be almost 16billion in 2100，but the low variant predicts it will peak at 8billion and decrease to just over 6billion by 2100．In most cases，it is the low variant that has come true in the past，suggesting the same will be true of their future population predictions．In addition to this，the size of families is actually decreasing．
For another，if the Earth is overpopulated，there needs to be insufficient （短缺） food，water，and space for humans to live．However，Indian economist Raj Krishna estimates that India alone is able to increase crop produce to the point of providing the entire world's food supply．The World Food Programme confirms that there is sufficient food grown to feed the world and there is the same amount of fresh water on the planet now as there was 10，000years ago．So how is it possible that the number of people in the world is affecting our planet？
Therefore，it is not an increase in population but an increase in consumption that is a severe threat．Materialism and overconsumption are facts of life for everybody in the western world，as possessions reflect a person's status in society and people strive to obtain happiness through owning the latest fashionable goods．Not only that，but waste is a common occurrence which has a huge effect on our resources．It is a sad truth that 80% of the world's resources are currently used by just 20% of the world's population．
Our overconsumption must be addressed now to make our lives more sustainable （可持續(xù)的） and avoid continuing the terrible damage to the environment we are causing．The key is education．If we do not work towards this but instead focus on the wrong issue，we may find ourselves living on a planet that can no longer sustain human life．
67．According to the author，what causes our current and future global problems？C
A．The increase in population．
B．Shortage of food and water．
C．The fast growth of material needs．
D．Failure to protect the environment．
68．The underlined word"myth"in Paragraph 2is closest in meaning toB．
A．fact B．misconceptionC．possibilityD．uncertainty
69．The author stresses thatC．
A．people should save food and water
B．economists are making wrong predictions
C．wrong judgment leads to serious consequences
D．measures should be taken to reduce population
70．What is mainly discussed in the passage？A
A．The real cause of global problems．
B．The severe effect of overpopulation．
C．Reasonable use of natural resources．
D．Methods to reduce overconsumption．

7．Around 200 people who thought their only experience of the London 2012 Olympic Games would be minor heats of synchronized swimming （花樣游泳） have received an unexpected change to the men's 100m final because of an embarrassing ticketing mistake．
The London 2012 Organizing Committee （Locog） confirmed on Wednesday that an error in its ticket selling had led to four synchronized swimming competitions being oversold by 10，000 tickets．
Locog and its ticket agent spent the Christmas period contacting ticket holders and offering them alternatives that included the tickets they had applied for but unsuccessful．The changes need no additional cost．It has also offered to return any discrepancy （差額） if the new tickets cost less than the originals．Locog said the replacement tickets would come from a number of unsold seats across the Olympic Games and that it was doing all it could to make up the error to the fans who bought tickets．
Locog said the error occurred in the summer，between the first and second round of ticket sales，when a member of staff made a mistake，entering"20，000"into the computer rather than the correct figure of 10，000 remaining tickets．The error was discovered when Locog checked the number of tickets that had been sold against the final seating numbers，and began contacting ticket holders before Christmas．
Thousands of ticket holders have already struck lucky，changing to tickets for major events including swimming and athletics finals，and in around 200 cases the hottest of all，the men's 100m final．Locog said the decision to award 100m final tickets was made because one of the synchronized swimming competitions was on the same afternoon as the event，August 5．

    A．will luckily be able to watch the men's 100m final

    A．Locog                                B．the ticketing mistake
    C．the Olympic Games                    D．the additional cost
39．How many ticket holders will have to change their tickets？B
    A.200．       B.10，000．

    B．Thousands of ticket holders refused to change their tickets．
