Many people think of the brain as a mystery.They don't know much about intelligence and how it works.When they do think about what intelligence is,many people believe that a person is born smart,average,or dumb—and stays that way in the whole life.But new research shows that the brain is more like a muscle—it changes and gets stronger when you use it.And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights,your muscles get bigger and you get stronger.A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time.That's because the muscles become larger and stronger with exercise.And when you stop exercising,the muscles shrink and you get weaker.That's why people say “Use it or lose it!”
But most people don't know that when they practice and learn new things,parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex(皮層)of the brain are billions of tiny nerve cells,called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things,these tiny connections in the brain actually multiply and get stronger.The more you challenge your mind to learn,the more your brain cells grow.Then,things that you once found very hard or even impossible to do—like speaking a foreign language or doing algebra(代數(shù))—seem to become easy after learning them for a period of time.The result is a stronger,smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals'brains.They found out that animals that lived in a challenging environment were more perspicacious—they were better at solving problems and learning new things.

Although cats may be one of the most popular pets today, little is known about how and when humans and cats set up their close relationship.
The earliest evidence for human–cat interaction dates back to prehistoric Cyprus(史前塞浦路斯), where the remains of a wild cat and a human — dated 9,500 years old — were found buried together.
A new study in the Proceedings of the National Academy of Sciences has confirmed the first direct evidence of a human–domestic cat relationship among Chinese farmers 5,300 years ago. Researchers studied the bones of cats, dogs, deer and other animals unearthed in an excavation (挖掘) near a village in Central China. By using some ways, scientists showed that the cats were living on a mostly millet(黍)–based diet, just like the domesticated dogs and pigs from the site.
"The most reasonable explanation for a high consumption of millet–based food is that the cats had formed a stable and mutual relationship with humans and could easily feed on rodents (嚙齒動物) around human villages, find leftover food or even have been fed by people intentionally," said Hu Yaowu from the Chinese Academy of Sciences in Beijing, whose research focuses on the relationship between humans and domesticated animals.
"It is very interesting for us to find the consumption of millet-based foods by the cats, since this kind of evidence had long been missing.” Hu explains. Since cats usually eat meat, such a diet would be unexpected, unless the cats were being fed by people, the study argues. The researchers also found that one of the cats survived to reach old age, implying that it had a safe place to live and enough to eat.
Why the farmers wanted to keep cats nearby or make them "pets" could be answered by other evidence. Chinese archaeologists found some storage containers were specifically designed to keep out rodents — a vermin (害獸) that cats could certainly have helped with.
The simplified theory is that rats were attracted to the food of farmers, and so were harmful to farmers. Cats were attracted to the rats, and so farmers formed a mutually beneficial relationship with cats, taking care of them in return for pest control.
小題1:The evidence found in the remains dating back to prehistoric Cyprus means         .
A.human made cats pets as early as 9,500 years ago
B.human interacted with cats very early
C.cats didn’t appear until prehistoric Cyprus
D.when cats became domesticated
小題2:Apart from cats, Hu Yaowu and his teams may also study         .
A.the preventions of pests from grains
B.the history of Chinese farming
C.the dogs and pigs
D.the ways to keep pets
小題3:Which of the following is NOT the evidence of Chinese farms’ keeping cats?
A.Cats didn’t feed on meat.
B.The cats consumed large amounts of millet–based foods.
C.One of the cats survived to reach old age.
D.Some storage containers were specifically designed to keep out rodents.
小題4:What are the reasons for farmers to keep cats?
A.Helping keep other domesticated animals.
B.Not letting cats eat food.
C.Supplying meat for human.
D.Helping reduce the amount of pests.
小題5:In which part of a newspaper would be the passage most probably appear         .

“iPhone 5”, the tallest thing to happen to iPhone since iPhone

We don’t want to change your phone, we want to make you say, “Wow, that is a bigger change than I expected”. “iPhone 5” is a result of that desire to surprise.
It’s been completely redesigned. For the first time ever, we’ve increased the size of display (顯示) by making the screen taller but not wider.
You can see more of your content without the need to scroll. We are making scrolling the thing of the past. It is more comfortable to use and reduces tiredness from scrolling when you read long documents.
Even with the larger display, it is the thinnest iPhone we ever built. To achieve the design this tall, we have to look at it and completely redesign the architecture inside. It’s 18% thinner and 79.5% taller than the previous iPhone. It makes everything you do on “iPhone5” easier. No more hidden menus, no confusing gestures. Everything is right at your fingertips.
The panorama feature (全景拍照) is simply awesome. The ultra HD (超高清) widescreen display lets you get your entire shot in a single snap (快門). You can also use its creative design for picture stabilization.
With an iPhone this tall, reception of signals has never been better. And of course, all your favorite applications are still available. In fact you will find your old favorites also benefit from the new experiencing handsome ultra HD widescreen. We found while many previous iPhone owners were using Facetime, they only used it for the faces. That’s why we are introducing Bodytime. With its ultra HD widescreen display, Bodytime lets you see a person’s entire body.

New research has revealed that which song drivers listen to can influence how safe they are on the roads.Among the top ten safest songs to drive to are Come Away With Me by Norah Jones,I Don't Want to Miss a Thing by Aerosmith and Tiny Dancer by Elton John.Each of the songs has an optimum tempo(最佳節(jié)奏) for safe driving,imitating the human heartbeat at around 60 to 80 beats per minute.The Scientist by Coldplay and Justin Timberlake's Cry Me a River also appeared in the top 10.
The study,conducted at London Metropolitan University,also revealed the type of songs that cause motorists to drive dangerously.Unsurprisingly,music that is noisy increases a driver's heart rate,which can be deadly.Fast beats cause excitement that can lead people to concentrate more on the music than on the road and to speed up to match the beat of the song.Styles of music were also measured during the experiment and revealed differences between male and female drivers.Hip­hop made a female driver drive far more aggressively,speeding up faster than male driver.The heavy metal music caused the fastest driving among males in the group while the dance music had the same effect among women.The male and female drivers who listened to the classical music drove the most irregularly.
The experiment involved eight people driving 500 miles each using the confused.com MotorMate app,which monitored driving behaviors through GPS technology.
小題1:What's the main idea of the whole passage?
A.Songs that drivers prefer to listen to on their way.
B.A study made by the confused.com MotorMate app.

During adolescence(青春期), peers(同齡人) play a large part in a young person's life and typically replace family as the center of a teen's social activities. Some kids give in to peer pressure because they want to be liked or because they worry that other kids may make fun of them if they don't go along with the group. Others may go along because they are curious to try something new that others are doing. The idea that "everyone's doing it" may influence some kids to leave their better judgment, or their common sense, behind. 
As children grow, develop, and move into early adolescence, contacts with one's peers and the attraction of peer identification (認同)increases. As pre-adolescents begin rapid physical, emotional and social changes, they begin to question adult standards and the need for parental guidance. They find it good to turn for advice to friends who understand— friends who are in the same position themselves. By trying new things and testing their ideas with their peers, there is less fear of being laughed at.
There are two levels of peer pressure. The first is in the large group: for most teens a school or a youth group are examples. This is the situation that gets the most attention. The second is in the close relationship with one or several best friends. This is the situation that is sometimes disregarded. The large group puts a general pressure on its members. It sets the standard for clothing, music, entertainment, and "political correctness". The pressure can be avoided by keeping quiet or by putting on the appearance of agreement.
小題1:Why can’t some children follow their common sense?
A.Because they want to be liked by everybody.
B.Because they don’t want to make fun of others.
C.Because they are curious about their new friends.
D.Because they think all the children will do the same.
小題2:When in pre-adolescence, who may children ask for suggestions?
A.ParentsB.TeachersC.FriendsD.Classmates
小題3:Which word can replace the underlined word disregarded in the last paragraph?
A.unnoticed B.mentionedC.disagreedD.a(chǎn)voided
小題4:What might be discussed in the following paragraph?
A.The reasons of peer pressure.
B.The advantages of peer pressure.
C.Peer pressure from close friends.
D.Peer pressure from a youth group.

Fahad Azad, an engineer in India, invented a robot named DuctBot.The toy-car sized DuctBot measured 23 centimeters in length, 19 centimeters in width and 9 centimeters in height and weighs just two kilograms.
The robot is designed to snake through dark, narrow air conditioning ducts (管道) and clean them.A pair of LEDs fitted on the robot light up the dirty scenery, so it can be captured (抓拍) by a camera.
In order to control it more easily, Mr. Azad chooses to fix DuctBot on wheels.The robot can clean off lots of dirt, as well as dead pigeons and insects.Keeping indoor air in good quality and monitoring carbon-dioxide levels in buildings with central air conditioning is a challenge.It is important in some places where clean air can mean a difference between life and death, such as hospitals.Dirty air has a bad influence on people's health.
EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad's invention in a national newspaper after he had won an international robotics competition.EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work.Across India, for example, the task still falls to children.They are small enough to go through those ducts.
In 2005, Mr. Azad who was still at university decided to do something about it.Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners.
Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage (污水)pipes.Their biggest challenge is to make the robots user-friendly enough.Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers.There will be lots of difficulties they need to overcome in the future.

In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about a half a dozen generate the strong, circling winds of 75 miles per hour or more that give them hurricane status, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.
The great storms that hit the coast start as innocent circling disturbances (氣旋) hundreds — even thousands — of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the trade winds. When conditions are just right, warm, moist (潮濕的) air flows in at the bottom of such a disturbance, moves upward through it and comes out at the top. In the process, the moisture in this warm air produces rain, and with it the heat that is switched to energy in the form of strong winds. As the heat increases, the young hurricane begins to turn around in a counter-clockwise motion (反時針方向).
The average life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released (釋放) by a hurricane’s rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months.
Water, rather than wind, is the main source of death and destroying in a hurricane. A typical hurricane brings 6-to-12-inch downpours resulting in sudden floods. Worst of all is the powerful movement of the sea — the mountains of water moving toward the low-pressure hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore.
小題1:An ordinary tropical storm is called a hurricane when ______.
A.it occurs in the Caribbean seas
B.its winds reach 75 miles per hour
C.it makes its way to the coastline
D.its winds begin to circle on the sea
小題2:What is the worst thing about hurricane?
A.The rough water.B.The violent winds.
C.The heat it gives out.D.The length of its life.
小題3:What does the third paragraph mainly talk about?
A.The hurricane is extraordinarily powerful.
B.The hurricane is used to generate electricity.
C.The hurricane can otherwise offer an unusual sight.
D.The hurricane can give people an unforgettable experience.
小題4:The counter-clockwise movement of the hurricane is caused by ______.
A.the low-pressure area in the center of the storm
B.the force of waves of water
C.the increasing heat
D.the trade winds

Should the color be white or black? Or perhaps navy blue! Well, choosing the right graduation dress for middle school students can be a little difficult at times. Here are some ideas for graduation dress for middle school students.
For many students, middle school graduation marks a big change in their lives. This is a step that takes students away from junior high school but towards the elementary level before senior high school. Compared to elementary (初級的) school, middle school means more lessons and more classes, but of course, students can also see it as an opportunity to make new friends.
Well, it is no wonder that the graduation day of a middle school is often planned formally. Although this occasion is not considered to be really formal like a high school graduation, it is still celebrated in many ways. Besides, it is also considered to be a very important part of someone's life.
Many schools often have middle school graduation parties. Well, the question that often arises in the minds of young students is about the right graduation dress for themselves. Long flowing dress with caps are commonly seen. Students should always stick to a common graduation dress that creates uniformity (統(tǒng)一) among all. The dress can be royal blue, black or even golden. If they seem too formal for the party, you can even plan for a common color for all the students. For example, white shirts with black pants or skirts can serve the needs of such a special occasion.
Whether the graduation party is simple or great, the graduation dress for middle school students should be planned accordingly. The main idea would be to accept the success of the students and celebrate with family and friends.
