What if I took that big jump on my bike?What’s the worst thing that could happen if I go out at midnight?Should try smoking?The teen years can play out like a choose-your-own-adventure novel.
Teenagers must act on an endless parade of choices.Some choices.including smoking.Come with serious consequences.As a result, adolescents often find themselves trapped between their impulsive tendencies（-Just try it!)and their newfound ability to make well-informed and logical choices（-Wait, maybe that’s not such a good idea!）.
So what makes the teenager’s brain so complex? What drives adolescents-more than any other age group-to sometimes make rash or questionable decisions?
If you have ever thought that the choices teenagers make are all about exploring and pushing limits, you are on to something. Experts Experts believe that this tendency marks a necessary period in teen development.The process helps prepare teenagers to confront the world on their own. It is something all humans have evolved to experience-yes, teens everywhere go through this exploratory period.Nor is it unique to people:Even laboratory mice experience a similar stage during their development.
For example，laboratory experiments show that young mice stay close by their mothers for safety. As mice grow．their behavior does too．“When they reach puberty，they’re like，‘I’m gonna start checking out how this environment looks without my mom，…explains Beatriz Luna,of the University of Pittsburgh．
As a developmental cognitive neuroscientist，Luna studies those changes that occur in the brain as children develop into adults．She and other researchers are showing how the teen experience can lead to powerful advantages later in life．Take mice again：Young mice that explore most tend to live longest——that is，unless a cat eats them，Luna adds．

You have some great ideas. But they don’t come out because of what your friends say or because you think that only a few people can be creative geniuses(天才). And, you, of course, think that you couldn’t be one of them. But actually, this is not true at all.
Anyone who is a creative genius will tell you that creativity is very much like a muscle that needs to be developed. If you don’t learn how to develop creative thinking, this skill, just like a muscle, will become poor and useless. On the other hand, keep working at it, and this skill will soon be ready for action whenever you need it. So how do you develop your own personal style of creative thinking?
You should realize that your brain has a greater capacity (容量) and a higher speed than the world’s biggest and fastest computer. So it’s important to get as much information as you can every day. Read, watch and listen to everything around you —good and bad. The more you know, the more you’ll want to know, and the more your brain will be exercised.
Try something new every day and let your experiences show you more about the world and people around you. You need to step out of your comfort zone (舒適地帶) more and more each day.
Follow these suggestions, and begin thinking beyond your "limits" from today. You’ll soon have a life full of interesting and exciting adventures. Who knows, your idea might be the next great idea to change the world.
【小題1】Most people can’t be creative geniuses because they _______.

A．don’t have great ideas
B．don’t want to develop their ideas
C．a(chǎn)re too shy to talk about their ideas
D．don’t believe they can be
【小題2】The underlined word "it" in the second paragraph means ________.
A．creative thinking B．the muscle C．personal style D．great capacity
【小題3】What do we learn from the passage?
A．No computer can store as much information as human’s brain.
B．It is not necessary to remember everything around you.
C．Try something new, as long as you are comfortable with it.
D．It is harder to exercise the brain than the muscles
【小題4】The passage is intended to tell readers _________.
A．how they can learn from creative geniuses
B．a(chǎn)bout ways to develop their creative thinking

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can’t see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones.
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “staff”, in an object.
Another kind of black hole is called “stellar”(星球黑洞). Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way.
The largest black holes are called “supermassive”(超大質(zhì)量黑洞). These black holes have masses that are more than one million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths.
Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole.
When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.
【小題1】The gravity of a black hole may become so strong that light cannot get out when ____________.

A．the star is going to die
B．special tools are used on it
C．other stars come close to it
D．it is seen from the space telescopes
【小題2】According to the passage, which of the following is NOT true?
A．A black hole can be very tiny but extremely heavy.
B．The gravity of a black hole holds all light in its center.
C．Scientists observe high-energy light through their own eyes.
D．Some small black holes came into being as early as the universe.
【小題3】The underlined word “galaxy” in Paragraph 5 means __________.
A．a(chǎn) black holeB．the Milky Way
C．a(chǎn) series of starsD．a(chǎn) planet near the earth
【小題4】What does the last sentence in Paragraph 5 suggest?
A．Neither the sun nor the earth is as heavy as a black hole.
B．There is a supermassive black hole at the center of the Milky Way.
C．The supermassive black hole had existed before the Milky Way was formed.
D．There is a reason why the large black holes are called “supermassive”.
【小題5】The last two paragraph mainly focus on the question of _________.
A．what a black hole is
B．how black holes form
C．how big black holes are
D．how scientists know about black holes

At the moment, there are two reliable ways to make electricity from sunlight. You can use a panel of solar cells to create the current directly, by liberating electrons from a semiconducting material such as silicon. Or you can concentrate the sun’s rays using mirrors, boil water with them, and employ the steam to drive a generator.
Both work. But both are expensive. Gang Chen of the Massachusetts Institute of Technology and Zhifeng Ren of Boston College therefore propose an alternative. They suggest that a phenomenon called the thermoelectric（熱電）effect might be used instead—and they have built a prototype（原型）to show that the idea is practical.
Thermoelectric devices are not new. They are used, for example, to capture waste heat from car engines. They work because certain materials generate an electrical potential difference within themselves if one part is hotter than another. That can be used to drive a current through an external circuit.
The reason thermoelectric materials have not, in the past, been applied successfully to the question of solar power is that to get a worthwhile current you have to have a significant temperature difference. (200℃ is considered a good starting point.) In a car engine, that is easy. For sunlight, however, it means concentrating the heat in some way. And if you are going to the trouble of building mirrors to do that, you might as well go down the steam-generation route, which is a much more efficient way of producing electricity. If the heat concentration could be done without all the equipment of mirrors, though, thermoelectricity’s inefficiency would be balanced by the cheapness of the equipment.
In their view, three things are needed to create a workable solar-thermoelectric device. The first is to make sure that most of the sunlight which falls on it is absorbed, rather than being reflected. The second is to choose a thermoelectric material which conducts heat badly but electricity well. The third is to be certain that the temperature gradient（梯度）which that badly conducting material creates is not wasted by poor design.
【小題1】The following methods can be adopted to make electricity from sunlight EXCEPT         .

A．putting a panel of solar cells into use
B．concentrating sun’s rays with mirrors
C．creating a solar-thermoelectric device
D．building a practical solar prototype
【小題2】Why was the application of thermoelectric materials a failure in the past?
A．Because it’s hard for them to build enough mirrors to make it work.
B．Because 200℃ was hard to reach at that time even in a car engine.
C．Because of the failure of having a significant temperature difference.
D．Because it was hard to focus the sun’s rays with equipment of mirrors.
【小題3】Which of the following is the best title for this passage?
A．Thermoelectric Device --- the Best Method of All
B．A New Method of Making Electricity from Sunlight
C．How to Create a Workable Thermoelectric Device
D．Solar Power --- a New Energy Trend in the Future

It’s the dirty little secret many shampoo companies don’t want you to know.  When you wash your hair with certain traditional chemical shampoos, you may actually be removing your hair and scalp（頭皮）of their natural oils.  These shampoos generate a thick bubble to clean hair, they can also create dryness, curl, dullness, and color fade. We then spend a lot of time and money on products that are effectively repairing the damage caused by shampoo.
Chaz Dean got tired of clients leaving his salon raving about their color and the feeling of their hair---brassy（似黃銅的） and dull. He knew the main cause was likely their shampoo, so he started experimenting with various ingredients, including natural herbs and botanicals, that he knew had cleansing（弄干凈）and hydrating (保濕的) properties.
The result was a totally new approach to the way we cleanse our hair.  It’s called WEN® Cleansing Conditioner.  WEN® contains a super-hydrating natural herbs and botanicals mixture of glycerin, chamomile(甘菊), rosemary, calendula, and Cherry bark, which when combined, will both cleanse the hair as well as give shine and softness, even to damaged hair.
WEN® is a 5-in-1 formula（配方） that takes the place of your shampoo, And the most amazing thing about it is that it cleanses without bubble.  Instead, when mixed with water, it creates a smooth bubble for shiny, healthy-looking, manageable results.  The first time you try it certainly feels strange, but the results speak for themselves.
Before being marketed, WEN® went through extensive consumer tests, and the results were impressive.  More than 90 percent of the participants in the studies reported that their hair was more shiny, less frizzy, and had more bounce.
WEN® is recommended for all hair types, and once you start using it, it will become the only cleanser/conditioner you will want to include in your daily routine.
Right now, WEN® is offering an easy way for online shoppers to try the product.  Now you just pay less than $30 and have a 60 day money back guarantee if you are not completely satisfied. Click here to learn more about WEN® and try this revolutionary new approach yourself.

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

Every year in late spring at Wild Friends, the wildlife health center, workers receive baby animals, including songbirds and rabbits. This is the busiest time when workers care for and raise all the little ones before sending them back into the wild.
There are many reasons for these little animals' coming to the center. First of all, street cats or dogs catch, injure or take away little birds from their nests. Sometimes people catch baby animals and keep them at home, giving them food that they are not used to. It would make them sick. Most people don't realize that it's against law to get live animals out of their nests.
As for songbirds, people often find them on the ground in their yards, thinking they have no other choice but to leave them on the ground to die. This is because many people wrongly believe that once a bird is touched by a person, its mother will not accept this child bird. But that's not true.
If a little bird falls out of the nest, you should check whether it is injured. If not, you should put the bird back in the nest. If the bird is injured, call your local wildlife center quickly.
As for the progress of protecting wild animals, people at Wild Friends devote all their energy to this work. Over the last weeks, they have been able to send many of the birds and rabbits that came here earlier this spring back to nature.
【小題1】Which is the busiest season for workers at Wild Friends?

A．SpringB．Summer.C．Autumn.D．Winter.
【小題2】Which of the following will probably injure young birds?
A．Giving them food they don't like.B．Letting them play with children.
C．Leaving them on the ground.D．Bringing them to the center.
【小題3】If a young healthy bird is lying on the ground, you should ________.
A．wait for its motherB．help it go back home
C．touch it with your handsD．call workers at Wild Friends

Global warming is causing more than 300,000 deaths and about $125 billion in economic losses each year, according to a report by the Global Humanitarian Forum, an organization led by Kofi Annan, the former United Nations secretary general.
The report, to be released Friday, analyzed data and existing studies of health, disaster, population and economic trends. It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition and heat-related health problems.
But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions. Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries,were being seriously affected by climate change. It projected that the number would double by 2030.
Roger Pielke Jr., a politicalscientist at the University of Colorado, Boulder, who studies disaster trends, said the Forum’s report was “a methodological embarrassment” because there was no way to distinguish deaths or economic losses related to human-driven global warming amid（在...中間） the much larger losses resulting from the growth in populations and economic development in vulnerable(易受傷害的) regions. Dr. Pielke said that “climate change is an important problem requiring our utmost attention.” But the report, he said, “will harm the cause for action on both climate change and disasters because it is so deeply flawed(有瑕疵的).”
However, Soren Andreasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.
In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability to climate hazards while still controling the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report.
【小題1】 What is the finding of the Global Humanitarian Forum?

A．Rates of death from illnesses have risen due to global warming.
B．Global temperatures affect the rate of economic development.
C．Malnutrition has caused serious health problems in poor countries.
D．Economic trends have to do withpopulation and natural disasters.
【小題2】 What do we learn about the Forum’s report from the passage?
A．It caused a big stir in developing countries.
B．It was warmly received by environmentalists.
C．It caused a lot of interest in the scientific circles.
D．It was challenged by some climate and risk experts.
【小題3】 What is Soren Andreasen’s view of the report?
A．Its conclusions are based on carefully collected data.
B．It is vulnerable to criticism if the statistics are closely examined.
C．It will give rise to heated discussions at the Copenhagen conference.
D．Its rough estimates are meant to draw the attention of world leaders.
【小題4】What does Kofi Annan say should be the focus of the Copenhagen conference?
A．How human and economic losses from climate change can be reduced.
B．How rich countries can better help poor regions reduce climate hazards.
C．How emissions of heat-trapping gases can be reduced on a global scale.
D．How rich and poor regionscan share responsibility in curbing global warming.

In the near future, we may be using our eyes to operate our smart-phones and tablets, even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years. But those devices have been firstly designed to help those with disabilities, and are very expensive.
“After a while, we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen. “where everybody would have this available."
Johansen and some of his colleagues have formed a new company, the Eye Tribe, which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements, the technology is then able to easily find where a person’s eyes are moving, and then allow the eyes to control a cursor(光標(biāo)).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at, ” reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Recently Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. But still, most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device. Johansen said a replaceable filter(濾光器)would be a cheap, convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

A．the eye-controlling technology was first developed for the blind
B．the present developing of the technology will bring no good
C．the eye-controlling technology is only intended for the disabled people
D．there is no such a phone as we can use only with our eyes at present
