Howling(吼叫) is a behavior commonly observed among a wolf pack(狼群). As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There’re different explanations of a wolf’s howl and it appears that there may be more to discover．
One theory is that wolves howl to bond better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behavior.
Indeed, there have been times when wolves have been seen one moment howling in a chorus(合唱), and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be “punished” for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status (地位) among its members? Why do wolves howl for sure?
What is clear, however, is that howling is often used among pack mates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering.
Howling, interestingly, is a contagious behavior. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of “roll call” where wolves all howl together to report their

Are you a compulsive spender，or do you hold on to your money as long as possible? Are you a bargain hunter? Would you rather use charge accounts than pay in cash? Your answers to these questions will reflect your personality．According to psychologists，our individual money habits not only show our beliefs and values，but can also stem from past problems．
Experts in psychology believe that for many people，money is an important symbol of strength and influence．Husbands who complain about their wives’ spending habits may be afraid that they are losing power in their marriage．Wives，on the other hand，may waste huge amounts of money because they are angry at their husbands．In addition，many people consider money a symbol of love．They spend it on their family and friends to express love，or they buy themselves expensive presents because they need love．
People can be addicted to different things —for example，alcohol，drugs，certain foods，or even television．They are compulsive in their addictions，i．e．they must satisfy these needs to feel comfortable．In the same way，according to psychologists，compulsive spenders must spend money．
For people who buy on credit，furthermore，charge accounts are even more exciting than money：in other words，they feel that with credit，they can do anything．Their pleasures in spending enormous amounts are actually greater than those they get from the things they buy．
There is even a special psychology of bargain hunting．To save money，of course，most people look for sales，low prices，and discounts．Compulsive bargain hunters，however，often buy things that they don’t need just because they are cheap．They want to believe that they are helping their budgets，but they are really playing an exciting game：when they can buy something for less than other people，they feel that they are winning．Most people，experts claim，have two reasons for their behavior：a good reason for the things that they do and the real reason．
It is not only scientists，of course，who understand the psychology of spending habits，but also business people．Stores，companies，and advertisers use psychology to increase business：they consider people’s needs for love，power，or influence，their basic values，their beliefs and opinions， etc．in their advertising and sales methods．
Psychologists often use a method called “behavior therapy（疗法）”to help individuals solve their personality problems．In the same way，they can help people who feel that they have problems with money：they give them “assignments” If a person buys something in every store that he enters， for instance，a therapist might teach him self discipline in this way：on the first day of his therapy， he must go into a store，stay five minutes，and then leave．On the second day，he should stay for ten minutes and try something on．On the third day，he stays for fifteen minutes，asks the salesclerk a question，but does not buy anything．Soon he will learn that nothing bad will happen to him if he doesn’t buy anything，and he can solve the problem of his compulsive buying．

PALO ALTO, California----"Switching off the television may help prevent children from getting fatter---- even if they do not change their diet or increase the amount they exercise," US researchers said last week.
A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet.
"The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician(儿科专家) at Stanford University.
"American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said.
In the study, presented this week to the Pediatric Academic Societies‘ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise.
"One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said.
"Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said.
小题1:The author tries to tell us in the first two paragraphs that ________.
| A．children will get fatter if they eat too much |
| B．children will get thinner if they eat less |
| C．children will get fatter if they spend less time watching TV |
| D．children will get fatter if they spend more time watching TV |
| A．is more than four hours a day |
| B．is less than four hours a day |
| C．doubled in the last twenty years |
| D．is more than on any other activities |
| A．six hours | B．eight hours | C．three hours | D．one hour |
A. They usually eat more while watching TV.
B. They burn off fewer calories.
C. They change their diet while watching TV.
D. Both A and B.
Lawmakers in the United States have expanded an investigation into the use of location-tracking systems on mobile devices. The action follows recent reports about the storing of information on the Apple iPhone. Some people consider location tracking to be a threat to personal privacy and security.
Allan Friedman, the research director, says, “All wireless companies do some location tracking as part of their networks. This information is usually stored by the companies, not the devices, and there are laws to protect it. Law enforcement(执法) agencies, for example, have to have a fairly high standard before it can access that data. And the phone company is also prohibited from selling that information.
Now, two researchers report that location tracking information is being stored directly on Apple devices. They said Apple’s newest operating systems gather global positioning system and timestamp information. The information is stored on the device in a file that is also uploaded (上传) to any computer that the device is connected to. The researchers say the information is available to anyone who has access to the device or computer.
Allan Friedman says, “This raises additional concerns. There’s the idea that because it’s on my phone and on my computer, rogue applications(恶意程序) that I pay for or that I’m tricked into downloading may be able to access this data and somehow misuse it.”
Apple says it is “not tracking the location of your iPhone”. It is simply keeping a database of Wi-Fi hotspots and cell phone towers near the user’s location. This information is meant to help the iPhone quickly find its location when needed.
Letters have been sent to some of the leading mobile device developers, including Apple and Google. The letters asked for more information about their location tracking systems. Allan Friedman calls this an important start to strengthening privacy laws. He says, “There aren’t strong controls over things like location information, what they are doing with it, how long they are keeping it. And perhaps the most important question is, is my location data with other facts about me?”
小题1:Why did American lawmakers investigate the use of location-tracking systems on cell-phones?
| A．Because the systems can store users’ information |
| B．Because many users have suffered loss after using them. |
| C．Because it is thought to threaten users’ privacy. |
| D．Because many reporters have shown the problem of the systems. |
| A．wireless companies focus on personal privacy. |
| B．people are forbidden to get access to private data at will |
| C．phone companies may sell private information secretly |
| D．customers may ask wireless companies to locate their tracking |
| A．Location tracking information is stored online. |
| B．Apple’s newest operating systems collect all kinds of information. |
| C．Location tracking information may be uploaded to any iPhone. |
| D．Apple’s newest operating systems may reveal the private information of users. |
| A．Apple denies that it tracks the location of users. |
| B．The researchers may misunderstand the Apple’s systems. |
| C．The global positioning system is to blame for rogue applications. |
| D．The iPhone can quickly find its location by using its user’s information. |
Can you imagine living in a house built by recycled waste?
Texas home builder Dan Phillips transforms trash into artful treasures, creating beautiful floors with wood pieces, kitchen counters from ivory -colored bones and roofs out of license plates （牌照）．
The fantastic houses which spring from his imagination are made almost entirely of materials which would otherwise have ended up in a garbage area．
" People have been doing this for hundreds of thousands of years; using whatever is available to build shelter, " Phillips said．"If you think about carefully what could be used, then building materials are everywhere．
The thirteen homes he has built so far would fit better in an art museum than the residential streets of Huntsville, a conservative town of about 35 ,000 people．
Living in these houses is a bit like living in a roadside attraction．"Almost every day, somebody knocks on the door and says " Is there any way that we could see?" "said Edie Wells, an artist who rents a room in the Bone House．Her home features a stairway made of bones, floors covered in wine corks （软木塞） and beer bottle caps．Wells said visitors are most impressed when they see a bathroom with its walls, floor and ceiling entirely covered with broken mirror pieces．
In addition, each house is highly energy efficient with plenty insulation （隔热材料） , an on-demand solar hot water heater and a system that can collect and recycle rainwater to clean the toilet and wash clothes．
Phillips founded Phoenix Commotion 12 years ago with the aim of creating a new model for sustainable housing．For as little as $ 10,000 it builds affordable homes for single parents, low-income families and artists．
The company has used hundreds of tons of construction waste by recycling the materials into habitable buildings．
Phillips tries to spread his recycled-house idea by speaking at events across the United States, and by using the Internet to reach out to like-minded individuals．Phillips said: "I"m not going to be saving the world anytime soon．But there needs to be at least some visibility for this model in this century．
小题1:Which of the following is NOT the advantage of the homes built by Phillips?
| A．environmentally-friendly | B．energy efficient |
| C．convenient | D．cheap |
| A．He is serious and hard-working． |
| B．He is full of imagination and intelligence． |
| C．It didn"t take him long to build the houses． |
| D．He didn"t give speeches in the United States． |
| A．made of bones | B．museums |
| C．admired by people | D．made of various trash |
| A．Home Builder Dan Phillips |
| B．Green Homes |
| C．Home Builder Dan Phillips Tunis Trash into Green Homes |
| D．A Home Builder" s Life |
Have you heard of the movie Benji off the Leashf This Benji story7 begins when his mother, a pretty black furry dog, escapes from the puppy mill with Colby, a boy who loves her．He tries to hide her in an abandoned house．The boy" s father discovers her there and takes mother and pups back home to the puppy mill, but leaves Benji behind because he doesn"t look purebred （纯血统的） enough to be sold for money．Colby comes back later to rescue the tiny puppy and keeps Benji in his wooden clubhouse, bringing Mom to come to visit him in secret．
As Benji grows bigger, it becomes harder to keep him in the clubhouse, and eventually the boy" s father discovers him and Benji is forced to flee to the streets．But despite his fear of Colby" s father, Benji cannot forget about his mother, who is growing steadily weaker and sicker．He continues to sneak back to the puppy mill yard to spy on the goings-on there and plan a way to rescue her．
Benji"s doggie pal, Scrappy enters the story when he is pushed out of a car into a country lane．Once his paws hit the ground, Scrappy wags his tail once helplessly after the car as it drives away, and then is immediately up to his neck in hapless mischief （顽皮）. Scrappy is a lovably stupid little dog who barely manages to escape the animal control officers who are determined to catch him．
One of the wonderful things about this movie is that the two stars are not highly trained purebred dogs．Both Benji and Scrappy were rescued mixed breed dogs found at local animal shelters．Adorable Benji and his stupid pal, Scrappy, demonstrate that mixed-breed rescue dogs are just as intelligent and trainable as any purebred dog．
Benji Off the Leash clearly demonstrates the connection between people who abuse animals and people who abuse people．Colby" s father takes out his anger on those who are weaker than him, namely by frightening his wife and the dogs．He attempts to frighten Colby, but the boy bravely refuses to let him．
Children who are used to fast-paced action films with catchy theme songs may not have the patience for the slower pace of this film．But for rescue volunteers, older children, and anyone who loves dogs, this is a heartwarming movie that shows how even in today" s world of deserted dogs and backyard puppy mills, there can still be happy endings for homeless dogs．
小题1:What can be learned from the passage?
| A．Two dogs star the movie． |
| B．The boy" s mother is very disgusting． |
| C．The movie will be liked by all the children． |
| D．The movie is fast-paced． |
| A．The movie is in praise of deserting homeless dogs． |
| B．We shouldn"t have mercy on homeless dogs． |
| C．We human beings need to love animals because they are our friends． |
| D．mixed-breed rescued dogs are less intelligent and trainable than purebred dogs． |
| A．Reviewing a Him． |
| B．Giving a summary of a movie． |
| C．Thinking highly of the relationship between animals and humans． |
| D．Criticizing people deserting animals． |
| A．To attract more people to see the movie． |
| B．To call on children to help homeless pets． |
| C．To show anger about abusing animals． |
| D．To urge people to care and love animals． |
