Interactive Home-security Systems
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.
What may Celebi first do if his front door opens at a wrong time when he is away?

A.Inform the police. B.Call his mother-in-law.
C.Arm the security alarm. D.Observe through video.

The interactive systems enable the user to ______.

A.improve his home environment remotely
B.lock his house's door while he is miles away
C.operate the home-security systems at any place
D.sound the alarm and inform the police at the same time

What's the advantage of the interactive systems over the traditional ones?

A.They are cheaper.
B.They are easier to set up.
C.They can give quicker reaction.
D.They have more ways to inform the users.

What is the last paragraph mainly about?

A.The importance of security industry.
B.The functions of the interactive alarms.
C.The popularity of home-security systems.
D.The market potential of the interactive systems.

Cittaslow has discovered China, and it is awarding a little village in Jiangsu the title of "slow city"
The bored teenagers of Gaochun are impatient with the leisurely pace of hometown life.For them there is no nightlife to speak of, no bright lights, no excitement and they cannot wait to grow up and leave for the urban attractions of the big cities.But it is this laid-back lifestyle that has attracted international attention.At least, a quiet village within Gaochun county has come under the spotlight.Yaxi village, population 20,000, is about to be designated China’s first "slow city" by Cittaslow, the sustainable lifestyle movement that first surfaced in Italy 11 years ago.
At home, the residents at Yaxi are unfazed and pretty much unimpressed by the honor.To them, life has been like this for as long as they can remember.Here, growing old gracefully is natural.
Nobody living in this little county had heard of Cittaslow or the words "slow city" before this.
"The first time I heard the term was last July, when the vice-president of Cittaslow, Angelo Vassallo, visited Yaxi village," says Zuo Niansheng, the chief editor of local newspaper Gaochun Today.
"Vassallo was deeply impressed by this village’s natural and cultural resources and said it perfectly fitted the requirements for a slow city," says Zuo."That was how Yaxi became connected with Cittaslow.
The Slow City must also be committed to protect and maintain the natural environment as well as promote a sustainable way of development ?all of which are the current strategies adopted in Gaochun."We’ve been doing this for years," adds Zuo.
Cittaslow was founded in Tuscany, Italy in 1999.It was a spin-off from the Slow Food movement which started, also in Italy, in 1986 as a protest against the first McDonald ’ s opening near the Spanish Steps in Rome.The movement championed a return to healthy, nutritious home-grown, home -cooked food.
Slow Food has since expanded globally to more than 130 countries.Its mission has also broadened to include the promotion of sustainable foods and local small businesses, and the localization as opposed to globalization of food production.
Cittaslow is an expansion of the Slow Food movement, and it actively advocates a lifestyle that is sustainable, that will improve quality of life, and will preserve cultural and culinary (烹饪的)heritage.
According the passage, Cittaslow is a(n) ____.

A.organization B.person C.lifestyle D.honor

What’ s the reaction of the residents at Yaxi to the award according the passage? They feel

A.it is full of excitement and activities of nightlife
B.the residents at Yaxi enjoy a leisure life
C.it is very rich and has a lot of attractions

It can be inferred from the passage that.

A.young people at Yaxi enjoy their life very much

C.the first McDonald’s in Europe was opened in Spain
D.the lifestyle of “slow city” will be good to environment and people

Contrary to common belief, social media websites such as Facebook do not weaken personal ties, they strengthen them in unique ways for different age groups, according to a new study.
The rapid spread of Facebook, which has more than 500 million users worldwide, has prompted concerns about its negative effects, but researchers at the University of Texas have reached a different conclusion.
"Our findings suggest that Facebook is not replacing face-to-face interactions between friends, family and colleagues," said S.Craig Watkins, an associate professor of radio, TV and film who headed the research team.
"In fact, we believe there is sufficient evidence that social media afford opportunities for new expressions of friendship, intimacy and community."
The researchers questioned 900 college students and recent graduates about how and with whom they interact on Facebook.
More than 60 percent of Facebook users said posting status updates was among the most popular activities, followed by 60 percent who wrote comments on their profile and 49 percent who posted messages and comments to friends.
The researchers also found that although about the same number of men and women use Facebook, they do so in different ways.
"There is a noteworthy difference in aims in how to use a tool like Facebook.We found that for women the content tends to be more affectionate, and (they) are especially interested in using it for connection," said Watkins.
"For men, it’s more functional," he added.
Watkins pointed out that, for example, women are more likely to post pictures of social gatherings with friends, while men are more likely to post pictures of hobbies, or post a political or pop-culture related link.
What’s the popular viewpoint of ordinary people about the function of social media websites? They think ____.

A.It is positive to personal ties
B.It has negative effects on personal ties
C.It makes no difference to personal ties
D.It has both good and bad effects to personal ties

Three-Dimensional (3D) movies have been becoming more and more popular in recent years.It seems 3D TV sets may be going into family households in the near future.While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say.

"There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist (眼科医师) in Chicago.He said in a 3D movie, these people face a completely new sensory experience."That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters.
In normal vision, each eye sees things at a slightly different angle."When that gets processed in the brain, that creates the perception (感觉) of depth," said Dr Deborah Friedman, an ophthalmologist in New York.The images people see in three dimensions in the movies are not calibrated (校准的) in the same way that their eyes and brain are."If your eyes are a little off to begin with, then it’s really throwing a whole degree of effort that your brain now needs
to exert (竭尽全力)," he said.
Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all.He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images.
Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off
Heineman said older 3D technology used two film projectors(放映机), one that projected a left-eye image and one that projected a right-eye image.Three-D glasses would allow viewers to see a different image in each eye.
"People often complained of headaches and it was really because the projectors weren’t lined up," Heineman said.
Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems.
"By going to a single digital projector, those problems were solved," he said.Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty (新鲜事物)."I suspect there will be a lot of people who say it’s sort of neat, but it’s not really comfortable," he said.
The text is mainly about ____.

A.the reasons why people like 3D movies
B.how to improve 3D technology
C.the development of 3D technology in recent years
D.causes of headaches and nausea when people watch 3D movies

The underlined phrase "took off" could be replaced by "______".

A.became popular
B.flew in the sky
C.left hurriedly
D.removed one’s clothes

This article implies that _____.

A.people do not like new things like 3D movies
B.3D TVs will completely take the place of old TV sets
C.3D technology is the most important technology ever
D.those with eye muscle problems should not watch 3D movies

We can learn from what Rosenberg said in the last paragraph that

A.a single digital projector could solve all the problems with 3D technology
B.people will gradually become comfortable with 3D movies and TVs
C.the appeal of 3D movies and "TVs may fade
D.most people will actually enjoy the 3D experience

Sitting by her Pinocchio lamp, she smiled at me as her tiny hands’ shadow danced on the bedroom wall."A rabbit!" she laughed with all the delight of a four-year old.Her blue eyes shone with pride as she showed me the animated image she had created."Daddy, will you show me how to make a tiger?" she asked."Sure," I said, "and then we’ll read a story and tell your angels goodnight."To my youngest daughter, that meant her bedtime prayer.
Today my daughter is seven, and I no longer get to read the story.She reads it to me, complete with expressive accents for the story characters.
To say I’m proud of our relationship would be an understatement.We have shared days of joy as well as tragedy.Our time together has strengthened the relationship of love and special "life stuff" that is all our own.
I am richer for having planted the spirit of trust in this gentle little person; we have grown together spiritually, learning much from each other.The special times we spend together, like nights by a Pinocchio lamp, create memories that we will treasure for the rest of our lives.
So it is with all of our relationships.The trust factor is vital for relationships to develop.Think of one of your fondest memories, and you will no doubt find a remarkable relationship at its center--one with a spiritual quality that shines outward from the heart.
Time together, caring acts, and unconditional love build trust.I suggest that we each spend plenty of time with our personal "Pinoechio lamps"--those special ways that we choose to strengthen our relationships.
Relationships take time to develop and maintain.It is not always easy, but the results are priceless."Nights by a Pinoechio lamp", wherever those might be for you, will create enduring relationships of golden "life stuff", spiritual gifts that no one can take away.
