     They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists
began finding infants' skills are more than they are supposed to be.
_________
     Speaking of music, babies can't seem to resist it. Not only are their ears turned to the beats, babies
can actually dance to the music.
     To test babies' dancing ability, the researchers played recordings of classical music, rhythmic beats
and speech to infants, and recorded the results. They also invited professional dancers to analyze how
well the babies matched their movements to the music. The babies moved their arms, hands, legs feet
and heads in response to the music, much more than to the speech. The finding suggests this dancing
ability is innate(与生俱来的) in humans, though the researchers aren't sure why it becomes weaker
later in their life.
     Learning Quickly while Sleeping
     Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping
infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes
200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each
baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air
upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids
in response to the sound by the end of the experiments.
     As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly
adapting to the world around them and help to ensure their survival, researchers said.
     Judging Characters Well
     Judging another person helpful or harmful is crucial when choosing friends. And that ability starts
early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in
which one character helped another climb a hill. In another scene a third character pushed the climber
down. The little ones then got to choose which character they preferred. For both age groups, most
babies chose the helper character. This character-judging ability could be baby's first step in the
formation of morals, Hamlin thought.
1. Which of the following subtitles can fill in the underlined blank?               
A. Dancing to Music                
B. Babies' Amazing Abilities
C. Learning to Dance Quickly          
D. Born to Dance
2. The underlined word "it" in the third paragraph refers to______.
A. the finding                      
B. the dancing ability    
C. the response                      
D. the baby
3. The experiment with 26 sleeping infants prove that_______.
A. babies can learn even while asleep
B. babies can respond to the world around them
C. babies can tighten their eyelids in response to the sound
D. babies can communicate with others while asleep
4. In the last experiment, most babies chose the helper character, showing that________.
A. babies can judge a person helpful or harmful
B. babies love to see a puppet show
C. babies were born to help others
D. babes have learned to help others

     We might like to think we're not influenced by other people, but a new study into the group-buying
mechanisms(机制) - like those used on coupon(优惠券) sites such as Groupon and LivingSocial-reveals
that telling buyers who come later to the offer how many have already signed up increases the number
of purchasers.
      Researchers at the University of Toronto's Rotman School of Management wanted to understand
why group buying sites that have entered the market recently have enjoyed greater success than those
operating a decade ago, such as Mercata and MobShop.
      Earlier attempts typically left potential buyers waiting for days before confirming whether or not they
had got the offer they had signed up for.
      "We think one of the reasons group-buying has been successful recently is because of the short tim
e horizon," says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and
PhD student Jiahua Wu. "It allows for a herding effect."
      Another reason is the use of an information structure that discloses to later arrivals how many have
already signed onto the deal.
      Researchers looked at two ways of designing the purchasing mechanism for a group buy: a
simultaneous mechanism, where no one knows how many buyers have come before them, and a
sequential(连续的) mechanism, where a second group of buyers has the advantage of knowing the
size of the first group.
      The researchers' analytical(分析的) model shows the most successful mechanism is the sequential
 one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of
those who sign on early, as they're able to track the numbers of those who come after them.
      "That boosts confidence," says Professor Hu, who teaches operations management. Deals for
"luxury" services, versus everyday items, work better in a group buy scenario(方案) because they offer
consumers a greater benefit.

1. It can be learned from the text that ______.
A. the short time horizon is the reason why group-buying has been successful.
B. a simultaneous mechanism is where a group of buyers has the advantage of knowing how many
people have signed up.
C. a sequential mechanism allows a herding effect which boosts the confidence of the buyers.
D. researchers at the University of Toronto's Rotman School of Management carried out an experiment
about why group buying sites entered the market successfully, such as Mercata and MobShop.
2. The underlined word "eliminates" in paragraph 7 probably means"______".
A. to become or to make something greater in amount, number, value
B. to remove or get rid of something
C. to deliberately not include something in what you are doing or considering
D. to make something known to somebody
3. What can be the best title for the passage?
A. Secret for marketing success - boosting confidence.
B. Secret for group-buying mechanism-herding effect.
C. Comparison between a simultaneous mechanism and a sequential mechanism.
D. What others do influences our decisions.

     The practice of magic includes special words, actions, and objects. Most magic involves a person
called a magician, who claims to have supernatural powers.
     Magic words. To work most magic, the magician sings or speaks special words in a certain order.
These words are called incantations or spells. Some spells form prayers to demons(魔鬼), spirits, or
other supernatural forces. Many societies believe the magic will not work unless the magician recites the
spells perfectly. Other magic words have no meaning, though they supposedly possess power when
spoken by a magician.
     Magic actions accompany the words spoken in performing much magic. Many of these movements
act out the desired effect of the magic. For example, a magician trying to make rain fall may sprinkle(洒)
water on the ground. The magician's combined words and actions form a ceremony.
     Magic objects include certain plants, stones, and other things with supposed supernatural powers. Any such object may be called a fetish(物神). But this term often refers to an object-for example, a carving
or a dried snake-honored by a tribe for its magic powers. Many tribes believe fetishes have magic power
because spirits live in these objects.
     Many people carry magic objects called amulets(护身符)to protect themselves from harm. Many
amulets are stones or rings engraved(雕刻) with magic symbols.
     The  magician. In some  societies,  nearly  everyone  knows  how to  work  some magic. In other
societies, only experts practice magic.Magicians may be called medicine men, medicine women,shamans,
sorcerers, or witch doctors. In many societies, magicians must inherit their powers. In others, any person
may become a magician by studying the magical arts.
     Many societies believe magicians must observe certain rules and taboos (forbidden actions) for their
spells to work. For example, they may be required not to eat various foods or to avoid sexual activity for
a certain period before the ceremony.
1.What do magic words mean to people in some society?
A.They have the power to kill devils.
B.They have power if magician recites the right spells.
C.They have no effect at all.
D.They can be used whenever they want.
2.People believe magic actions will have an effect if they are accompanied by________.
A.the spells
B.magic objects
C.stones or rings engraved with magic symbols
D.medicine
3.Why do many people believe in a fetish?
A.Because it is often a ring which is worth a lot of money.
B.Because it is carved with magic symbols.
C.Because people think spirits live in it.
D.Because it can help them with many things

     I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded
that today's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for
mental illness 50 years ago.
     Why are America's kids so stressed? The report cites two main causes: increasing physical isolation
(隔离) brought on by high divorce rates and less involvement in community, among other things and a
growing perception that the world is a more dangerous place.
Considering that we_can't_turn_the_clock_back,_adults can still do plenty to help the next generation.
     At the top of the list is nurturing(培育) a better appreciation of the limits of individualism. No child is
an island. Strengthening social ties helps build communities and protect individuals against stress.
To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your
family will thank you later. They will have more time for facetoface relationships, and they will get more
sleep.
     Limit the amount of virtual(虚拟的) violence your children are exposed to. It's not just video games
and movies; children see a lot of murder and crime on the local news.
     Keep your expectations for your children reasonable. Many highly successful people never attended
Harvard or Yale.
     Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a
good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have to ruin your life.
1.According to the analysis, compared with normal children today, children treated as mentally ill 50 years ago ________.
A.probably suffered less from anxiety
B.were considered less individualistic
C.were less isolated physically
D.were probably less selfcentered
2.What does the author mean by saying "we can't turn the clock back" in the third paragraph?
A.It's impossible to forget the past.
B.The social reality children are facing cannot be forgotten.
C.It's impossible to slow down the pace of change.
D.Lessons learned from the past should not be forgotten
3.The author thinks that the conclusions of any research about people's state of mind are ________.
A.illogical  
B.confusing
C.surprising  
D.questionable
4.Which of the following statements is TRUE according to the passage?
A.To children, anxiety is completely avoidable.
B.TV and computer play an important role in isolating children from the real world.
C.Exercise does not help to lessen children's anxiety.
D.Sometimes local news about crime and murder also affects children a little

     Japanese high school students either walk or ride bicycles if the distance is not too great. In other cases, students must take public buses and trains. After junior high school, students attend schools based on their high school entrance examination scores. So some students travel a great distance to attend the school.
     At school
     The school day begins at 8:30. Then students assemble in their homeroom classes for the day's studies. Each homeroom has an average of 40-45 students. Students stay in their homeroom classrooms for most
of the school day. Only for physical education, laboratory classes, or other subjects requiring special
facilities(设备) do students move to different parts of the school. Between classes and at lunchtime,
classrooms can be noisy, lively places. Some schools may have a cafeteria(自助餐厅), but most do not.
In most schools, students bring a box lunch from home, prepared by the mother in the early morning hours.
     Japanese students spend 240 days a year at school, 60 days more than American students. Students in high schools take three years' each of the following subjects mathematics, social studies, Japanese, science, and English. Other subjects include physical education, music, art, and moral(道德的) studies. All the
students in one grade level study the same subjects. Given the number of required subjects, electives(选修科目) are few.
     Afterschool Activities
    Club activities take place after school every day.Students can join only one club, and they rarely change clubs from year to year, so the clubs are relatively stable. Clubs are made up of sports clubs ( baseball,
soccer, judo, kendo, etc.) and culture clubs(English, broadcasting, science, etc.). New students usually
are encouraged to select a club shortly after the school year begins in April. Clubs meet for two hours after school each day and many clubs continue to meet during school vacations.
1.Most Japanese high school students often have their lunch________.
A.in restaurants  
B.in school cafeterias
C.at home

A.  The likely reason of global warming
B.Global warming-a world problem
C.The fast increase in recent years
D.What we should do to avoid greenhouse gases producing
E.The earth is becoming warmer
F.Different opinions on the cause of global warming
     1________
     Is the world warming up? According to many reports, the answer is yes. Eleven of the hottest years
since 1850 appeared between 1995 and 2006. Last year, the United Nation's Intergovernment Panel on
Climate Change (IPCC) reported the earth was about 0.75 ? warmer than it was in 1850. While this
doesn't sound like a lot, a small difference in average temperature can make a big difference in climate.
During the last Ice Age, the planet was only about five degrees colder than now.      
     2.________
     It's all about the speed at which temperatures are changing. In the past,temperatures moved up or down step by step. But in the 20th century,  especially since 1976,  temperatures  have  likely risen more quickly
than during any century in the last 1000 years. Warming may bring improved harvests to northern countries such as Canada  and  Russia.  However,  many species won't like  these  conditions.  They begin moving
towards cooler places and cause lots of trouble to human world.
     3.________
     The IPCC reported that human activity is very likely responsible for increasing the greenhouse effect.
Some gases  cause the air  to  take in  heat  energy. Without  the greenhouse effect,  the  earth's average
temperature would be-18? rather than the present comfortable 14.6 ?. The main greenhouse gases are
carbon dioxide, water vapor and some other gases. Burning oil,coal and waste add to the carbon dioxide,
and it has increased 35% since 1850.
     4.________
     Many researchers have found that natural forces alone don't explain the temperature increases over the
last 30 to 40 years. Their study shows that as carbon dioxide goes up, temperature will rise, too. But some scientists don't agree. They think the effect of human produced greenhouse gases is very small compared
to the normal changes that the climate causes.
     5.________
   When asked whether humans are causing the world warming,Carl Wunsch, a professor at Massachusetts Institute of Technology says, "It seems very likely from what I've seen. Is it 100% sure? No. There is
something to do with natural changes." Does that mean we should have a "waitandsee" attitude? No. He
points out we buy house insurance not because we are sure our homes will be on fire, but because it's a
danger we'd rather avoid.

     Even plants can run a fever, especially when they're under attack by insects or disease. But unlike
human, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago,
adopting the infrared(红外线)scanning technology developed for military purposes and other satellites,
physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which
ones are under stress. The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than
rain poison on a whole field, which invariably includes plants that don't have pest problems.
      Even better, Paley's Remote Scanning Services Company could detect crop problems before they
became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured
the heat emitted by crops. The data were transformed into a colourcoded map showing where plants
were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they
otherwise would.
     The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted
the new technology and longterm backers were hard to find. But with the renewed concern about
pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation.
Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of
agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who
recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be
adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain
10 years ago.

1. Plants will send out an increased amount of heat when they are________.
A. facing an infrared scanner
B. sprayed with pesticides
C. in poor physical condition
D. exposed to excessive sun rays

2. In order to apply pesticide spraying precisely, we can use infrared scanning to________.
A. estimate the damage to the crops
B. draw a colourcoded map
C. measure the size of the affected area
D. locate the problem area

3. Farmers can save a considerable amount of pesticide by________.
A. resorting to spotspraying
B. transforming poisoned rain
C. consulting infrared scanning experts
D. detecting crop problems at an early stage

4. The application of infrared scanning technology to agriculture met with some difficulties-_______.
A. its high cost
B. the lack of official support
C. the lack of financial support
D. its failure to help increase production

5. Infrared scanning technology may be brought back into operation because of________.
A. full support from agricultural experts
B. growing concern about the excessive use of pesticides on crops
C. the forceful promotion by the Department of Agriculture
D. the desire of farmers to improve the quality of their produce

     Nuclearpowered aircraft carriers are considered one of the most important marine weapons in the
20th century. So far, only two countries in the world, the USA and France, have ever produced them.
But these fearful fighting machines are about to enter Asia.
    The US Navy said last month that one of its nine nuclearpowered aircraft carriers will be sent to
Japan to replace the diesel(柴油)powered carrier Kitty Hawk in 2008. In an agreement on October
30, the two countries also planned to level up their military (军事的) cooperation and the USA called
for Japan to take a larger role in alliance military moves.
     It will be the first time that a nuclearpowered carrier is based in Japan. Bombed by US forces in
World War ? at Hiroshima and Nagasaki, Japan is the only world country to have been attacked by
a nuclear weapon. Therefore, the citizens are highly sensitive to where nuclearpowered weapons are
based.
     "A radiation leak at Yokosuka would kill 100,000 people as far away as Tokyo, and could cause
billions of dollars in damage, " said Masahiko Goto, leader of a protest group in Yokosuka. His group
has collected more than 300,000 signatures of people across Japan opposed to the nuclear carrier.
     The 44yearold Kitty Hawk, the US Navy's oldest active ship, has been based in Yokosuka since
1998. It had returned to the US to be decommissioned in 2008. The new carrier, yet to be unveiled,_
will travel faster, be capable of supporting longer operations and carry with it the Navy's most modern
technology.
     Experts pointed that this change is not only to strengthen the USJapan military alliance but also to
keep the military power of China and North Korea within limits. However, even Japanese experts don't
believe that the two countries are threats to the region.
    "There is no need for Japan to have a nuclear carrier as defense, " said Tetsuo Maeda, an international
relations professor at Tokyo International University. He said that the change of ship indicates an
increased military capability in the region, much more than what is needed.

1. With such a formidable weapon to enter its country, Japanese citizens ________.
A. are aware of its benefits to the country
B. are anxious about its potential danger
C. are curious about the advanced technology
D. are against where the carrier will be based

2. The replacement of the aircraft carrier is intended to________.
A. set up a kind of base in Japan
B. strengthen the USJapan military alliance
C. show Japan's greater military capability
D. get rid of the dated marine weapon

3. From the story, we learn that________.
A. no other countries except the USA and France possess aircraft carriers
B. Japan has long planned to increase its military capability with new weapons
C. Japan will be the first country in Asia to have a nuclear aircraft carrier
D. Japan will be the third country to produce a nuclearpowered aircraft carrier

4. The underlined word "unveiled" in the fifth paragraph probably means________.
A. perfected  
B. discussed about
C. produced  
D. brought to view

5. By his remark in the last paragraph, the professor means that________.
A. he is quite confident of their military defense
B. he is completely opposed to a new nuclear carrier
C. what is needed is far more than a nuclear carrier
D. it is unnecessary to guard against the two countries

     I heard many parents complaining that their teenage children are rebelling. I wish it were so. At your
age you ought to be growing away from your parents. You should be learning to stand on your own two
feet. But take a good look at the present rebellion. It seems that teenagers are taking the same way of
showing that they disagree with their parents. Instead of striking out boldly on their own, most of them
are clutching (紧握) at one another's hands for reassurance.
     They claim they want to dress as they please. But they all wear the same clothes. They set off in new
directions in music. But somehow they all end up huddled (聚在一起) round listening to the same record. Their reason for thinking or acting in thusandsuch a way is that the crowd is doing it. They have come out
of their cocoon (蚕茧) into a larger_cocoon.
     It has become harder and harder for a teenager to stand up against the popularity wave and to go his
or her own way. Industry has firmly carved out a teenage market. These days every teenager can learn
from the advertisements what a teenager should have and be. And many of today's parents have come
to award high marks for the popularity of their children. All this adds up to a great barrier for the
teenager who wants to find his or her own path.
     But the barrier is worth climbing over. The path is worth following. You may want to listen to
classical music instead of going to a party. You may want to collect rocks when everyone else is
collecting records. You may have some thoughts that you don't care to share at once with your
classmates. Well, go to it. Find yourself. Be yourself. Popularity will come-with the people who respect
you for who you are. That is the only kind of popularity that really counts.

1. In this passage, the author wants to tell ________.
A. teenagers to try to pursue their real selves
B. readers to try to be popular with people around
C. parents to try to control and guide their children
D. people to try to understand and respect each other

2. The author disapproves of rebelling teenagers ________.
A. growing away from their parents
B. following the popularity trend
C. walking a new way on their own
D. turning to their friends for help

3.The phrase "larger cocoon" at the end of the second paragraph refers to ________.
A. the distractive and variable society
B. the dazzling music world
C. the parental care and love
D. the popularity wave in the society

4. What does the author think of advertisements?
A. Convincing. 
B. Instructive.
C. Influential.  
D. Authoritative.

5. According to the author, what might happen when a teenager stands up against the popularity
