More and more people take part in marathons these days – over 30,000 people will run the London Marathon this weekend, for instance. But it’s not just the 26 miles and 385 yards that could be a daunting prospect. “I have to admit to being completely frustrated by the blocking and for 18-19 miles was just keeping away from people and being held up,” one participant grumbled after the 2012 London Marathon. “I had to overtake a lot of people and ended up with bruised（淤腫的）forearms from all the elbows,” said another.
How do such crowding problems arise, and could they be reduced? Some researchers believe that we can find the answers through a more familiar system in which jams appear – road traffic flow. Martin Treiber, of the Technical University of Dresden in Germany, has previously developed models for traffic flow. One of the first attempts to model traffic flow was made in the 1950s by James Lighthill and his collaborator Gerard Whitham of Manchester University. They considered the traffic as a kind of liquid flowing down a pipe, and looked at how the flow changes as the fluid gets denser(濃稠). At first the flow rate increases as the density increases, since you simply get more stuff through in the same period of time. But if the density becomes too high, there’s a risk of jams, and the flow rate drops sharply.
Treiber’s model of a marathon uses this same principle that the flow rate first increases and then decreases as the density of runners increases, thanks to an sudden switch from free to crowded flow. He assumes that there is a range of different preferred speeds for different runners, which each maintains throughout the race. With just these factors, Treiber can calculate the flow rate of runners, knowing the “carrying capacity”(承載能力)at each point on the route.
This allows Treiber to figure out how blocking might depend on the race conditions – for example, for different starting procedures. Some marathons start by letting all the runners set off at once (which means those at the back have to wait until those in front have moved forward). Others assign runners to various groups according to ability, and let them start in a series of waves.
Treiber has applied the model to the annual Rennsteig half-marathon in central Germany, which attracts around 6,000 participants. The traditional route had to be changed in 2013, because the police were no longer willing to close a road to ensure that runners could cross safely. It could pass either over a 60m wooden bridge or through a tunnel. Treiber used his model to predict the likely blocking caused in the various options. The model predicted that a mass start would risk an overload of runners if the bridge were to be used. Only by moving the starting point further back from the bridge could the danger be avoided – and even then, if some of the numbers assumed in the model were only slightly inaccurate, there was still a risk of jams at the bridge. On the other hand, no dangerous blocking seemed likely for the tunnel route. The run organizers consulted Treiber’s team, and eventually chose this option.
小題1:What is the worst thing while running a marathon?
A．The long distance.B．Too many participants.
C．The dangerous blocking.D．Serious injuries in forearms.
小題2:Which of the following statements is true?
A．James Lighthill is the first expert trying to model traffic flow.
B．The denser the flow is, the faster the flow rate becomes.
C．The flow rate increases in the beginning because fewer people passed together.
D．The flow rate increases first and then decreases later when the flow is too denser.
小題3:What is NOT true about the Rennsteig?
A．It has much less participants than the London Marathon in 2014.
B．It has a shorter distance than the London Marathon.
C．The route was changed because the traditional one is not safe any longer.
D．The participants running this marathon will pass a tunnel because this choice is safer.
小題4:What’s the main idea of the passage?
A．Make a comparison between marathon and road traffic.
B．Running a marathon is somewhat dangerous if it is not well organized.
C．Introduce a new technology to solve the blocking problem in marathon.
D．Some advice for people who are to run a marathon.

Having finished her homework，Ma Li wants some music for relaxation(娛樂(lè))．As usual，she starts her computer and goes to Baidu.Come to download music files.But this time she is surprised when an announcement about protecting songs'copyright bursts onto the screen.The age of free music and movie downloads may have come to an end as Web companies like Baidu are accused of pirating copyright.Lawsuits(訴訟)have been filed against four websites offering free downloads.In September 2005, a Beijing court ordered Baidu to pay recording company Shanghai Push compensation(賠償)for their losses.Baidu was also told to block the links to the pirated music on the website.This caused a heated discussion on Internet file sharing.
“Baidu's defeat in the lawsuit shows it is not right to get copyrighted songs without paying.Downloaders may face lawsuits or fines，”said an official.
Like many teens，Huang Ruoru，an 18­year­old girl from Puning in Guangdong Province，doesn't think that getting music from websites is wrong.She always shares her favourite songs downloaded from Baidu with her friends.When told about the lawsuit，she began to feel a little guilty about obtaining others' work without paying.
However，other teenagers have different ideas.Wang Yafei，a Senior 2 girl from Jinan，Shandong Province pointed out that file sharing is a good way to promote pop singers.“If I download a song and really like it，I will buy the CD，”she said.“So what the recording companies really should concentrate on is improving their music，rather than pursuing(追趕，追擊)file­sharers.”
小題1:Which of the following best describes the passage?

Some students get so nervous before a test; they do poorly even if they know the material. Sian Beilock has studied these highly anxious test­takers.
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry，it actually uses up attention and memory resources. I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher，Gerardo Ramirez，have developed a possible solution. Just before an exam，highly anxious test­takers spend ten minutes writing about their worries about the test.
Sian Beilock: “What we think happens is when students put it down on paper，they think about the worst that could happen and they reappraise the situation. They might realize it's not as bad as they might think it was before and，in essence(本質(zhì)上)，it prevents these thoughts from popping up when they're actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of  B＋，compared to a B－ for those who did not.
Sian Beilock: “What we showed is that for students who are highly test­anxious，who'd done our writing intervention(排解)，all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don't normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.
小題1:Which of the following is TRUE?
A．The result in the math test agrees with that in the biology test.
B．In the first math test, students who sat quietly performed better.
C．In the second math test, students who wrote about their feelings did worse.
D．Some college students are highly anxious test­takers while others are not in the tests.
小題2:What may happen if students have the problem of test anxiety?
A．Test anxiety is sure to cause students to fail the test.
B．Test anxiety can improve students' performance to some degree.
C．Students' attention and memory resources run out when worried.
D．Students may not be admitted into their favorite college if worried.
小題3:The result of the research suggests that ________.
A．proper amount of burden may turn out to be a good thing
B．facing the fears bravely may help one to achieve more
C．a(chǎn)voiding facing the problem may contribute to relaxation
D．taking no action before difficulty may result in success
小題4:What is the main idea of the passage?
A．It is important for students to overcome test anxiety.
B．Anxious students overcome test anxiety by writing down fears.
C．It is a common practice for students being worried before a test.
D．Being worried before tests does harm to students' performance.

IMAGINE that you are in school, giving a speech to your class.
Now think what it feels like when stammering(口吃)makes it a struggle to communicate your thoughts and feelings to other people.
The King’s Speech, which won the best picture at
the Academy Awards, highlights(突出) stammering along with other speech-related problems. The movie tells the story of Britain’s King George Ⅵ, who became king after his brother Edward Ⅷ gave up the crown to marry an American woman.
As a result of British actor Colin Firth’s performance, people are starting to realize that stammering can damage a person’s self-confidence and cause him/her to escape from life.
“The problem is unseen and unheard,” said Norbert Lieckfeldt, an expert at the British Stammering Association, in an interview with The Guardian newspaper.
“Stammering masks(遮蓋) your ability,” he said, “It's a serious disability(殘疾).”
Most stammerers face bullying(欺負(fù)) in school, something that is “usually carried over into the workplace”.
George Ⅵ’s stammer took away his confidence as a speaker. But Samantha Mesango, a speech coach based in the UK, believes that speech problems are more common than most people realize. “Some simply don't like the sound of their own voice; others are scared of speaking in public,” she said.
Travis Treats from Saint Louis University’s department of communication sciences in the US, praised The King’s Speech. He said it shows that “how one’s speech does not mean what one is inside”.
He also added that people who stammer need to be heard and our society should recognize that they have a lot to give to the world.
小題1: What is the point of the first two paragraphs?
A．To tell readers about speech speaking.
B．To show how harmful a stammer is.
C．To draw the attention of readers to the problem of a stammer.
D．To show how a stammer makes a person popular
小題2: According to the article, King George Ⅵ _____.
A．was a hero during World War Ⅱ
B．took the place of his brother
C．married a divorced American woman
D．was a failure because of his stammer
小題3: What is Norbert Lieckfeldt’s view of the challenge of a stammer?
A．A stammer can destroy a person’s self-confidence.
B．A stammer is a serious problem for many people but it is often ignored.
C．People who stammer need to have their own voice.
D．People who stammer do better in work than in school.

What could be cuter than your puppy giving his doggy friend a kiss on the nose? Nothing, really. But is your dog actual-fly planting a kiss on his friend? Yes, but that’s only one of the reasons your dog may lick another dog’s nose. Here are some other reasons why your dog may lick another dog’s nose.    
During an introduction, a shy and lower-ranking dog will lower his head, avoid direct eye contact and gently extend his tongue to lick the nose of a more confident and high-ranking dog. The first dog licks the nose of the second dog to simply make it know that：he comes in peace.
Dogs who are already friends will also trade kisses. Two strongly bonded dog pals will lick and clean each other. They give each other “dog kisses” showing friendship.
Puppies also “kiss” their mothers, but it's not a gesture of love. When puppies stop suckling(吸吮)their mothers’ tits for milk and start to eat semisolid(半固體)food instead；they lick their mothers’ mouths and noses in the hope of getting the mother to regurgitate(反哺) some semi-digested food.
So how to help your bashful dog make friends with other dogs? You can carefully select confident-but-friendly and good-tempered dogs to play with your shy dog, to help him develop his social skills. Also consider taking him to a special training class that focuses on socialization and positive training technique.
Do not disturb them when your two dogs play “kiss” briefly with each other. Sit back and enjoy this display of friendship. Then call them over and have them do a command such as “sit’’ or “shake paws”. Offer them treats as a reward for being good to each other.
If you foster(收養(yǎng))a dog and have three or more resident dogs, introduce the foster dog to your brood dog one at a time and let muzzle licking between them happen naturally. Start with your least reactive or most friendly dog. Never force an in production between the dogs because this can deepen the foster dog’s submissiveness or spark a fight.
小題1:We know a shy and lower—ranking dog licks the nose of a higher-ranking dog to        .
A．a(chǎn)sk the dog for helpB．show he is friendly
C．show his anger D．show his respect for him
小題2:What can we know about two dogs who are already friends?
A．They seldom give each other kisses.
B．They usually avoid direct eye contact.
C．They like keeping their friendship a secret.
D．They show their friendship by “dog kisses”.
小題3:What does the underlined word “bashful” in Paragraphs 5 mean?
A．Shy. B．Honest. C．Lovely.D．Little.
小題4:What should you do if your two dogs play “kiss” briefly with each other?
A．Ask them to stay away from each other immediately.
B．Ask them to shake tails.
C．Ask them to have a fight.
D．Give them a reward for being friends.
小題5:The writer wrote this passage to_________.
A．tell us about a study he did recently
B．explain why a dog kisses other dogs
C．tell us how to raise dogs
D．help us to make friends with dogs.

Tarik Celebi, who lives in San Francisco suburb, takes his home-security system with him to work, to dinner, just about anywhere．By his cell phone, he "arms" his home-security alarm from his car before he leaves for work．During his workday, he gets e-mail alerts every time his front door opens, even though he's miles away．If the door opens at an unusual time -say midday when no one should be coming or going - he can order a 30-second video clip（片段） from the camera that watches the door．If it's just his  mother-in-law getting a package delivery, no worries．
Celebi is one of the first users of the latest interactive home-security systems．In addition to sounding alarms when the house is broken into and notifying homeowners or police, as traditional systems do, the interactive systems give users new ways to remotely control their systems and their home environment．Different from traditional home-security alarms, which homeowners typically have to press buttons on a keypad to turn on before they leave their homes, the interactive systems enable consumers to arm and disarm systems from smart phones, iPads and PCs, no matter where they are．
Most traditional systems are set up to sound an alarm if doors or windows are opened． The interactive systems give homeowners more options．For example, users can elect when they want to be notified．They might want an e-mail or a text every time a door is opened, or only during the hours of 3 to 4 p．m．, when kids come home from school．Like Celebi, they can add cameras and get video clips when doors open．That could be helpful in making sure kids aren't bringing friends home when they're not supposed to．
Nationwide, about 20% of homes have．traditional home-security systems．About half stop using them because they tire of the trouble．Being able to arm systems even while dashing to the subway or while at work will increase their usage of the new interactive systems．Although the new functions add costs to home security, the interactive-systems are believed to push home-security systems' usage rates closer to 30%, which would be a big movement for an industry that's been largely stuck at 20% for the past decade．"We all know it's going to get bigger, though we don't know how long it's going to take," Eric Taylor, an officer from San Francisco Security Department says．
