The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蟻堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通風(fēng)口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.
The engineering firm of Ove  Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned building, where up to 30% of the air is recycled.
小題1:What’s the meaning of “complex” in the second paragraph? 
A．Something that is difficult to understand.
B．A group of buildings together in one place.
C．A group of things that are connected.
D．A mental state that is not normal.
小題2:How is fresh air from outside drawn out?
A．By fans.B．Via ceiling vents.
C．Through chimneys.D．Via ceiling vents and through chimneys.
小題3:What is NOT the factor that makes Eastgate Building work well?
A．Skies without clouds.
B．Little dampness.
C．Daily rapid temperature changes
D．Seasonal rapid temperature changes.
小題4:In general, how is the daily temperature of the building?
A．It changes in a certain range with some exception.
B．It changes from one extreme to another.
C．It remains the same without any exception.
D．It is hard to endure.
小題5:What’s the main idea of the passage?

Many people don't realize the importance of music education in the schools today．A new study showed, however, music education is extremely important．
In college, music education is one of the largest programs．Teachers have to learn general education materials and techniques． They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more．At the same time, much of our culture and tradition is absorbed in music．
Music plays a very important role in our education．
Music helps with math and science． Students learn to count, and how to multiply and divide．Students also use science to help them discover what sounds good together and what doesn't．Students also need science to understand something called the “overtone series", which is about how music is produced by vibration（顫動(dòng)）and why．
Students learn a lot about languages through music．Many songs are written in other languages, including ancient ones．Students must learn to translate these works to understand what they are singing about． A song is likely to be a famous short work set to music; so students are exposed to that very often while singing．
Students learn a huge amount of cooperation （協(xié)作）of body parts through music, so parts of the body can work better together．Students must use motor（肌肉運(yùn)動(dòng)的）skills in order to play an instrument．Singers and wind（管樂(lè)器）players must learn breath control and be in good shape to play．
Students learn about art． Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they're playing the music．
Music education also brings higher thinking to our children．It allows them to think about complex patterns．Students have to be aware of what every other musician does at every time．In that way, it develops cooperation, as well．They tend to develop more ability for learning．
As one can see, music is very important to education．
小題1:According to the passage, learning music in college will be quite         ．
A．easyB．stressfulC．a(chǎn)ttractiveD．useless
小題2:As to the benefits from music, which of the following is NOT included in the passage?
A．Calculation．B．Language study．
C．Relaxation．D．Cooperation of body parts．
小題3:The underlined word "that" in Para．5 refers to“            "．
A．the musicB．the language
C．the cultureD．the work
小題4:What can we know from the passage?
A．Science and music are extreme poles．
B．Only the wisest person can learn music well．
C．Music is good to our all-round development．
D．All of us know the importance of music clearly．

A good teacher is many things to many people. In my own experience, the people I respect the most and think about the most are the teachers who demanded (要求) the most discipline (紀(jì)律) from their students.
I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very vividly (清晰地) a sign over her classroom door. It was a simple sign that said, “Laboratory—in this room the first five letters of the word was emphasized (強(qiáng)調(diào)), not the last seven.” In other words, I guess, labor for her was more important than oratory, which means making speeches.
She prepared her work very carefully and demanded us to do the same. We got lots of homework from her. Once she had broken her arm, and everybody in the class thought that maybe the homework load would be reduced, but it continued just the same. She checked our work by stamping her name at the bottom of the papers to show that she had read them.
I think sometimes teachers who demand the most are liked the least. But as time goes by, this discipline really seems to benefit (有益于) the students.
小題1:Which of the following is considered a good teacher by the writer?
A．A patient teacher.B．An honest teacher.
C．A strict teacher.D．A hard-working teacher.
小題2:The teacher put up the sign over her classroom door ___.
A．to remind the students that this room was a laboratory
B．to advise the students to follow the disciplines
C．to warn the students not to be careless
D．to tell the students to work hard in the classroom
小題3:When the teacher’s arm was broken, she ___.
A．gave her students the usual amount of homework
B．gave her students less homework
C．a(chǎn)sked her students to check the homework themselves
D．gave her students more homework
小題4:What’s the writer’s opinion of discipline?
A．It makes the students dislike their teachers.
B．It does good to the students in the long run.
C．It’s too much for young children.
D．It does more harm than good to the students.

Remembering names is an important social skill. Here are some ways to master it.
Recite and repeat in conversation
When you hear a person’s name, repeat it. Immediately say it to yourself several times without moving your lips .You could also repeat the name in a way that does not sound forced or artificial.
Ask the other person to recite and repeat
You can let other people help you remember their names. After you’ve been introduced to someone, ask that person to spell the name and pronounce it correctly for you. Most people will be pleased by the effort you’re making to learn their names.
Admit you don’t know
Admitting that you can’t remember someone’s name can actually make people relaxed. Most of them will feel sympathy if you say, “I’m working to remember names better. Yours is right on the tip of my tongue. What is it again？”
Use association
Link each person you meet with one thing you find interesting or unusual. For example, you could make a mental note: “Vicki Cheng-tall，black hair”. To reinforce your association, write them on a small card as soon as possible.
Limit the number of new names you learn at one time.
When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering everyone. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
Go early
Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That’s fewer names for you to remember. And as more people arrive, you can hear them being introduced to others-an automatic review for you.
小題1:If you can’t remember someone’s name, you may________
A．tell them the truthB．tell them a white lie
C．a(chǎn)sk him for pityD．a(chǎn)sk others to help you
小題2:The underlined word “reinforce” mostly means “______”.
A．getB．simplifyC．strengthenD．collect
小題3:When you meet a group of people, it is better to remember______
A．a(chǎn)ll their namesB．a(chǎn) couple of names first
C．just their last namesD．a(chǎn)s many names as possible
小題4:What does the text mainly tell us?
A．How to recite and repeat namesB．Importance of attending parties
C．How to make use of associationsD．Tips on an important social skill

Parents are fuelling bad behavior among their children by attempting to "buy" their love with expensive gifts nowadays.
Over recent decades we seem to have created a "must have" culture among our young people. Many mothers and fathers believe they are "failing as parents" if they are unable to ensure that their children have the latest toy, electronic devices (the lap-top, cellphones, Game Boy, etc.) along with their friends. In many cases, families also feel pressured to enroll (使加入) children in "'every interest club or after-school activity that is available" to fill up their time like most of the other children.
But experts warned that the move might affect "precious family time" negatively. Graham Gorton, chairman of the Independent Schools Association, said that parents spent too much time filling their children's lives, which had a series of negative effects on "the very precious family time that exists".
"It seems that those times when a whole weekend without planned work was seen as a luxury (奢侈) and a perfect opportunity to spend time together and share those valuable moments of childhood are long gone," Mr. Gorton said. "As a child I only once said that phrase that parents feared 'I'm bored'. Immediately my mother took action and produced a list of jobs and then insisted that I complete every one of them. Though l didn't think cleaning all the floors could really get rid of my boredom, I enjoyed the feeling of staying at home with my mother and brothers."
Earlier this year, some researchers suggested that relatively wealthy parents were sometimes guilty of failing to teach basic social skills to children. "Often, it’s the rich middle classes that buy off their children through the computer and the TV. That then sets them apart from their family, and then the parents are surprised when their child isn’ t coming to school."
小題1:The second paragraph mainly tells us that ________.
A．today’s children have little time to play
B．today’s children depend on electronic tools too much
C．today’s parents feel pressured by the "'must have" culture
D．being qualified parents becomes harder for today's young people
小題2:What does the "must have" phenomenon refer to based on the passage?
A．That children must have what other children have.
B．That children must have proper pressure to work hard.
C．That children must have special skills to ensure a better future.
D．That parents must have patience to know their children better.
小題3:Which of the following is the best advice you could give to parents based on Gorton’s statement?
A．Plan fewer activities for their children to improve family time.
B．Buy their children fewer things that they are fond of.
C．Give their children more housework to do.
D．Leave their children alone when the kids feel bored.
小題4:Mr. Gorton tended to think that in the past ________.
A．children enjoyed doing housework
B．children never thought life was boring
C．children liked to spend time with their family
D．children often had some planned work after school
小題5:From the passage we can infer that ________.
A．wealthy parents don’t like teaching basic social skills to children
B．parents should be much more strict with their children at home
C．children should not be brought up in a wealthy and pleasant environment
D．only satisfying children’s material needs is not a good way of parenting

Pupils remember more and behave better when 3D images are used in lessons，research suggests．They are quicker to learn and absorb new concepts，and display higher levels of concentration．
Professor Anne Bamford，of the University of the Arts，London， studied the effectiveness of 3D content in 15 schools across seven countries，including the UK．Pupils in 3D classes can remember more than those in the 2D classes after four weeks，improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons．They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿動(dòng)作) to answer the test questions successfully．
The teachers commented that the pupils in the 3D groups had deeper understanding，increased attention span．more motivation and higher engagement in the lessons．
Children are used to 3D with the rise of computer games that use the technology—90 percent of those in the study had seen a 3D film．Schools would need 3D—enabled projectors(投影儀)，laptops with good picture capabilities，3D software and glasses for children to introduce animations(動(dòng)作) into classrooms．
But Danny Nicholson，an educationist，said the technology would be impractical to use in schools and could be costly．He said，“While I think the idea of 3D technology is very interesting， I worry that 3D is a bit of an expensive gimmick(小玩意兒)．There are a few cases where a true 3D image might help，but most of the time，good 2D models that can be moved would be just as effective．”
In the US，one school district in Colorado is already in the process of having 1．000 3D projectors fixed in classrooms．And the University of Caledonia．which carries out scientific research into the Lake Tabon Basin．has used 3D presentations with Grade Six pupils．Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version．
小題1:What is the main idea of the first three paragraphs?
A．There are slight differences between 3D and 2D images．
B．Pupils perform better when 3D images are used in classes．
C．Schools have difficulties in making full use of 3D technology．
D．3D technology is always more effective than 2D technology．
小題2:Danny Nicholson holds the view that 3D_____.
A．is of no help in classes
B．has a bright future in classes
C．is more practical than 2D models
D．may not be affordable for schools
小題3:What can we learn from the last paragraph?
A．3D technology will replace 2D models in the future．
B．Many pupils are now more Interested In science than before．
C．Teachers will use the 3D technology through specific training．
D．3D will soon be put into use in one school district in Colorado．
小題4:The underlined word “engrossed” in the last paragraph means_____.

【1】People study their family history for different reasons. For some, genealogy(家譜學(xué)) is important to their religion（宗教信仰）. Other people who get involved in genealogy may want to confirm （證實(shí)）stories they heard about a family member. Some people say their interest in genealogy came from an eight-part series on television called Roots. Roots was first broadcast in 1977 and was based on a book which describes how the author’s ancestor, long ago in Africa, as slave was brought to America. After watching Roots, many Americans wanted to study ________________.
【2】Finding family roots is not always easy. So how exactly does someone start a genealogical research?
【3】Experts say you should start with yourself. Write down your own history. One idea is to ask your parents what they can remember about their parents or grandparents. You can often find a lot of information in family pictures, letters and other documents.
【4】Resources on local history may also provide useful information. Large libraries may have hundreds of helpful books. In the United States, several groups have large collections of genealogical materials. These collections are open to the public.
【5】Governments often have many helpful records of genealogies. Governments usually keep official copies of birth, marriage and death records. Local governments may have copies of wills. These statements of final wishes often contain details about a person’s life and wealth.
【6】Today, many people use the Internet. There are thousands of websites related to genealogy. They can guide people to historical records and provide information about how to write down their family’s history.

閱讀下面短文，從各題A、B、C、D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。
Your brain isn’t a muscle, but you can treat it like one
Many people focus on physical fitness, but few know that brain fitness is also something you can work on. In fact, you can exercise your brain as often as you do to your arms or legs —and the results can be positive and empowering.
To improve your brain, you can’t simply repeat the same exercises over and over. Just as lifting a two—pound weight will stop challenging you, so will repetitive exercises such as crosswords or Sudoku. Once you master easy exercises, you must move on to harder ones in order to push your brain —like your muscles —to a new level.

The science behind brain training
Scientists once believed that your mental abilities were fixed in adulthood. Since studies have shown just the opposite, millions of people around the world have adopted the new practice of brain training. The most popular of these brain training products is made by the San Francisco—based Lumosity. Lumosity's scientists with an experienced team of game designers have developed a fun，effective online brain training program that measures，tracks，and adapts to your progress，so you'll always be challenged.
Promising studies on the effects of brain training
In a 2013 Stanford study，a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed，mental flexibility，and working memory tasks. On average，those who trained improved on tests of these abilities，compared to a group that did not train with Lumosity.
There is even some evidence suggesting that Lumosity may be beneficial to normal，healthy adults. In a 2011 study by Lumosity and San Francisco State University researchers. 13 people who trained over 5 weeks improved working memory scores by 10％and attention scores by 20％.
Brain training is designed to meet real-life needs
The design of brain training is targeted at real-life benefits instead of improving game scores. Better attention，for example，can mean greater focus in the classroom or at an important business meeting. With improved processing speed，you might react and adapt faster to the demands of a busy life. And a better memory could mean stronger，longer relationships with the people closest to you.
小題1:We can learn from the passage that _________.
A．brain training speeds up the recovery of breast cancer
B．your brain is like a muscle because it gives you power
C．people's mental abilities can't develop after they grow up
D．Lumosity can measure，track and suit your level as you improve
小題2:Which skill may brain training not improve?
A．Better attention. B．A better memory.
C．Better writing skills.D．Higher processing speed.
小題3:What can we infer from the passage?
A．People should care more about physical health instead of mental health.
B．Brain training has been proved effective through scientific researches.
C．A bad memory is the only reason for weak relationships with people.
D．Playing online games is the best way of brain training.
小題4:What's the best title for the passage?
A．Brain Training Makes a DifferenceB．Train Your Brain like a Muscle
C．Lumosity，Your Best ChoiceD．How to Train Your Brain

Koala bears as pets might be appealing to many of us. However, there are quite a few points to consider even before thinking of adopting one.
Koala bears are one of the most lovely Australian animals. In certain cases where the koala has been raised by hand, they have turned out to be quite affectionate pets. These people tied a piece of fur to a pillow and placed it beside a joey (a baby kola) as a substitute (替代物) for the mother koala. This trick seemed to work well with the baby koala. However, it is a known fact that human handling causes stress to koalas. In my personal opinion, this aspect clouds the fact that koala bears can be tamed (馴服).
In Australia the koala is a priority animal as far as conservation status assessment is concerned. It was hunted to near extinction (滅絕) for its fur. In fact the koala had been wiped out from South Australia in the 1920s. However, rehabilitation efforts have brought the animal back in the state. As for the Australia government, the koala is not a threatened animal, but the US government does list the koala as one.
Although they may live in 40 to 60 kinds of eucalyptus trees, they prefer only 10 to 14 specific kinds. Koalas sleep for most part of the day, which is about 16 to 18 hours, and for most of their waking hours all they do is eat. Koala bears eat the leaves of eucalyptus trees. A full-grown koala can eat almost 2 to 3 pounds of leaves in a day. Despite their slow movements and sweet look, koala bears can be vicious when hungry. Other than this, there are the stress caused to koalas due to human handling and the fights that start in koalas.
Almost everyone finds koalas lovely in the zoo. However, as far as having koala bears as pets is concerned, there are legal issues to consider. Other than that, being able to provide for its diet and habitat is another point that needs some attention before any law legalizing their adoption as pets is passed.
小題1:What’s the author’s attitude towards people raising the koala?
A．Optimistic.B．Grateful.C．Cautious.D．Enthusiastic.
小題2:Why did Australians hunt the koala?
A．To get its fur.B．To eat its meat.C．To wipe it out.D．To have it for fun.
小題3:The underlined word “vicious” in Paragraph 4 probably means __________.
A．fierce and dangerousB．patient and friendly
C．a(chǎn)fraid and defensiveD．lovely and interesting
小題4:It can be inferred from the passage that __________.
A．koala bears tend to live in groups
B．koala bear care can be very demanding
C．koala bears are not particular about their food
D．koala bears are the No. 1 threatened animal in the US
