Have you ever wondered why birds sing? Maybe you thought that they were just happy.After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy.However, they sing most of the time for a very different reason.Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a "territory" is? A territory is an area that an animal, usually the male, claims as its own .Only he and his family are welcome there .No other families of the same species are welcome.Your yard and house are your territory where only your family and friends are welcome.If a stranger should enter your territory and threaten you, you might shout.Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him.A bird does the same thing.But he expects an outsider almost any time, especially at nesting (筑巢) season.So he's screaming (高聲尖叫) all the time, whether he can see an outsider or not.This screaming is what we call a bird's song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.You can see that birds have a language of their own.Most of it has something to do with attracting mates and setting up territories.
小題1:Some scientists believe that most of the time birds' singing is actually
A.a(chǎn)n expression of happiness
B.a(chǎn) way of warning

A.A place where a bird may shout at the top of its voice.
B.A place where other bird families are not accepted.
C.An area for which birds fight against each other.
D.An area which a bird considers to be its own
小題3:Why do birds keep on singing at nesting season?
A.Because their singing helps frighten outsiders away.
B.Because their singing helps get rid of their fears.
C.Because they want to find outsiders around.
D.Because they want to invite more bird friends.
小題4:How does the writer explain birds' singing?
A.By comparing birds with human beings.B.By reporting experimental results.

Brrriiinnng.The alarm clock announces the start of another busy weekday in the morning.You jump out of bed, rush into the shower, into your clothes and out the door with hardly a moment to think.A stressful journey to work gets your blood pressure climbing.Once at the office, you glance through the newspaper with depressing stories or reports of disasters.In that sort of mood, who can get down to work, particularly some creative, original problem-solving work?
The way most of us spend our mornings is exactly opposite to the conditions that promote flexible, open-minded thinking.Imaginative ideas are most likely to come to us when we’re unfocused.If you are one of those energetic morning people, your most inventive time comes in the early evening when you are relaxed.Sleepy people’s lack of focus leads to an increase in creative problem solving.By not giving yourself time to tune into your wandering mind, you’re missing out on the surprising solutions it may offer.
The trip you take to work doesn’t help, either.The stress slows down the speed with which signals travel between neurons (神經(jīng)細(xì)胞), making inspirations less likely to occur.And while we all should read a lot about what’s going on in the world, it would not make you feel good for sure, so put that news website or newspaper aside until after the day’s work is done.
So what would our mornings look like if we wanted to start them with a full capacity for creative problem solving? We’d set the alarm a few minutes early and lie awake in bed, following our thoughts where they lead.We’d stand a little longer under the warm water of the shower, stopping thinking about tasks in favor of a few more minutes of relaxation.We’d take some deep breaths on our way to work, instead of complaining about heavy traffic.And once in the office—after we get a cup of coffee—we’d click on links not to the news of the day but to the funniest videos the web has to offer.
小題1:What is the purpose of the first paragraph?
A.To tell us a specific story.
B.To introduce the topic of the passage.
C.To indicate how busy one usually is in the morning.
D.To show mornings are not suitable for creative work.
小題2:What does the author imply about newspapers?
A.They are normally full of bad news.
B.They are solution providers.
C.They are a source of inspiration.
D.They are more educational than websites.
小題3:By “tune into your wandering mind” (in Para.2), the author means “_______”.
A.wander into the wildB.listen to a beautiful tune
C.stop concentrating on anything D.switch to the traffic channel
小題4:The author writes the last paragraph in order to _______.
A.establish a routine for the futureB.summarize past experiences
C.a(chǎn)dvocate diverse ways of life D.offer practical suggestions

Televisions, stereos, telephones, and computers have changed the way we spend our time and what we know about the world. Some of the changes brought about by these material possessions have improved our way of life, but others have made it worse. Our young teenagers turn on the television, play the stereo, play games on the computer, talk on the telephone, and eat all the same time. This drives me right up the wall to instant insanity(精神失常).
However, teens of today place too great an importance on material property. They spend an average of several hours a day watching television, listening to stereos, playing on the computer, playing video games, and talking on the telephone. Families no longer watch television together and there is great lack of communication. Materialism is evident when an otherwise intelligent teenager drives their parents crazy, and into debt, when misusing communication equipment. Teens judge and admire other teens for what they own and have, rather than for what they are or what they can do. They no longer care about values, like honesty, integrity(正直), freedom, talent, quality and other values and morals.
However, good or bad, communication devices are here to stay. It is up to us, as parents, to stop our beloved teenagers from misusing and abusing our communication equipment and devices. We need to avoid the problems they present and to make the most of their opportunities they possess and hold for us all.
小題1:The writer’s attitude toward the modern material possessions is generally _____.
A.positiveB.negativeC.neutralD.indifferent
小題2:According to the writer, teens’ overuse of communication equipment can do harm to _____.
A.their own healthB.their own study
C.their own moralityD.their neighbors’ life
小題3:The writer attributes (歸咎) the unsatisfactory behavior of teens to _____.
A.teens’ too much free timeB.parents’ non-interference
C.inadequate school educationD.material property
小題4:It can be inferred from the passage that the writer seems to be most annoyed at ______.
A.a(chǎn)ll the modern material possessionB.eating while talking on the phone
C.the decline in teens’ moralityD.a(chǎn)ll the communication equipment

Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive (自我毀滅的) acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.
According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
Think back to the time you took your very first sip (啜飲) of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (誘惑) you need will power to resist, they never, ever start out that way.
Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (諷刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.
小題1:What do most people think causes bad behavior?
A.Being forced by others.
B.Not having enough will power.
C.Enjoying their first experiences.
D.Following the examples of their friends.
小題2:The author mentions his experience in the third paragraph to prove ____.
A.will power helps develop bad habits sometimes
B.drinking beer is harmful to the health of teenagers
C.self-control should be developed when one is young
D.everyone can be challenged by different temptations
小題3:In the last paragraph, the author stresses that ____.
A.without self-control, no one can succeed
B.bad habits don’t always lead to bad results
C.a(chǎn)pplying self-control correctly is important
D.people can develop wisdom from bad behavior
小題4:What would be the best title for the passage?
A.My First Sip of Beer
B.Do You Have Will Power ?
C.Will Power Benefits Us
D.Dark Side of Self-control

Language-learners who say they never or hardly ever use dictionaries often speak English well but usually write poorly, because they make many mistakes.
The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. So they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations (翻譯) of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English.
The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables (音節(jié)), they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check these in a dictionary.
小題1:Students who never use dictionary speak well but write poor, because_______
A.They can’t remember words.
B.They may make mistakes.
C.They are not interested in writing.
D.They are afraid of writing.
小題2:According to the passage, which of the following is right?
A.Students who never use dictionary can speak well and write well.
B.Whatever new words you meet while reading, just look them up in the dictionary.
C.Small two-language dictionaries are bad for learning English.
D.An English word only has one translation.
小題3:When does the writer advise students to use a good dictionary in reading?
A.At the beginning of the reading
B.At the end of the reading
C.During the first reading
D.After the first reading

A.that students shouldn’t use small two-language dictionaries
B.what were the defects (缺點(diǎn)) of small two-language dictionaries
C.why students should use large college edition dictionaries
D.what dictionary students should choose and how to use it

Why play games? Because they are fun, and a lot more besides. Following the rules… planning your next move…acting as a team member… these are all “game” ideas that you will come across throughout your life.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating.
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones, which sharpens the hand-eye coordination (協(xié)調(diào)) needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it — some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.
小題1:Through playing hide-and-seek, children are expected to learn to ________.
A.be a team leader
B.obey the basic rules
C.a(chǎn)ct as a grown-up
D.predict possible danger
小題2:The underlined part in Paragraph 2 most probably means that games can ________.
A.describe life in an exciting way
B.turn real-life experiences into a movie
C.make learning life skills more interesting

Switching telephone providers used to be the only way homeowners could save money on telephone bills. Now thanks to new technology, comsumers have another choice-making phone calls over the internet. And this can be completely free if you call another person with an internet phone set-up.
The technology is called voice over internet protocol (協(xié)議), or VoIP. In 2005, consumer demand for VoIP dramatically grew. In the US, where popularity has grown faster than here in the UK, 8.4 million are predicted to subscribe this year. For the past couple years, VoIP pioneers such as Skype have accounted for the majority of internet phone subscribers.
VoIP is attractive to consumers because it’s cheaper than traditional phone services. With the basic equipment of PC, microphone and headset, and VoIP software and broadband internet for optimum (最適宜的) voice quality, consumers can save a fortune chatting for free to other internet phone owners and save money calling regular landlines (通訊電纜). But, as the saying goes, you get what you pay for. Many of these services suffer from uncontinuous lapses (失效) in quality. While some users may tolerate echoes or a dropped call, improved quality is needed to attract more customers.
Computing has examined the benefits of using a PC as a telephone with VoIP in how easy they were to set up, how effective they were and the range of their features.
Skype(www. skype.com) came top for its bother-free approach, easy set-up and exceptional voice clarity. Sipgate (www. sipgate. co. uk), MSN(www. messenger. msn. co. uk) and Yahoo! Messenger (uk. messenger. yahoo. com) provide an audio “wizard” that improves sound levels. Google Talk (www. google. com/ talk) was less helpful and Babble. net (www. babble. net) was let down by its poor help files. Yahoo! Messenger provides some of the best features, including the option of landline calls, webcam chats, instant messaging, voice-mail and conference calls.
小題1:Which one of the following if you call others?
A.VolP,voice over internet protocol
B.Switching telephone
C.New technology
D.letters
小題2:The underlined sentence in Paragraph 3 implies that ______.
A.VoIP can save money but it has some disadvantages
B.whatever you buy is related to how much you pay
C.what you pay for will belong to you forever
D.what you buy is not always high in quality
小題3:Which of the following statement is true according to the passage?
A.Sipgate is less helpful.
B.Yahoo! Messenger offers some best features.
C.Skype is the best one in the new technology.
D.Google Talk provides very good audio “wizard”.

For high school leavers starting out in the working world,it is very important to learn particular skills and practice how to behave in an interview or how to find all internship(實(shí)習(xí)).In some countries,schools have programs to help students onto the path to work.In the Unites States,however,such programs are still few and far between.
Research shows that if high schools provide career-related courses,students are likely to get higher earnings in later years.The students are more likely to stay in school,graduate and go on to higher education.
In Germany,students as young as 13 and 14 are expected to do internships.German companies work with schools to make sure that young people get the education they need for future employment.
But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world.Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track.Schwartz argued that this approach leaves the country’s most vulnerable(易受影響的)kids with no jobs and no skills.
Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high school.James Madison High School in New York,for example,encourages students to choose classes on career—based courses.The school then helps them gain on—the-job experience in those fields while they’re still at high school.
However,even for teens whose schools encourage them to connect with work,the job market is daunting.In the US,unemployment rates for 16-to 19-year-olds are above 20 percent for the third summer in a row.
“The risk is that if teenagers miss out on the Summer job experience,they become part of this generation of teens who had trouble in landing a job,”said Michael,a researcher in the US.
小題1:In the author’s opinion, American high school leavers__________.
A.have enough career-related courses
B.need more career advice from their schools
C.perform better in exams than German students
D.can get higher earnings in later years
小題2:According to Robert Schwartz,_________.
A.there is no need for kids to go for higher education in the US
B.students should get contact with the working world at high school
C.education reform should focus on students’ performance in exams
D.teenagers in the US can’t miss out on the summer job experience
小題3:What can be inferred from the text?
A.Unemployment rates for US teenagers remain high at the moment.
B.Students with career—based courses never have problems finding a job.
C.US companies work with schools to prepare young people for future employment.
D.High school leavers with no practical skills can’t find a job absolutely
小題4:What’s the main idea of the text?
A.Arguments about recent US education reform.
B.Tips on finding jobs for high school leavers.
C.The lack of career—based courses in US high schools.
D.Advice for American high school leavers.
小題5:The underlined word “daunting” in Paragraph 6 most probably means___________.
A.discouragingB.interesting
C.creativeD.unbearable

Even at school there had been an unhealthy competition between George and Richard.
“I’ll be the first millionaire in Coleford!” Richard used to boast.
“And you’ll be sorry that you knew me,” George would reply “because I’ll surely be the best lawyer in our town!”
After graduation, George never became a lawyer and Richard was anybody but a millionaire …. Instead, it happened that both men opened bookshops on opposite sides of Coleford High Street, while it was hard to make much money from books then, which made the competition between them worse. Eventually, Richard closed down his, dreaming of making a fortune elsewhere. 
Now, with only one bookshop in the town, business was better for George. But sometimes he sat in his narrow old kitchen and gazed out of the dirty window, thinking about his former rival (競(jìng)爭(zhēng)對(duì)手)。Perhaps he missed him?
George was very interested in old dictionaries, and he had recently found a collector in Australia who was selling a rare first edition. When the parcel arrived, the book was in perfect condition and George was quite delighted. But while he was having lunch, George glanced at the photo in the newspaper that the book had been wrapped in. He was astonished — the smiling face was older than he remembered but unmistakable! Trembling, George started reading: “Bookends Company has bought ten bookstores from its competitors. The company, owned by multi-millionaire Richard Pike, is now the largest bookseller in this country.”
小題1:George and Richard were        at school.
