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． |

“Our aim is to take our art to the world and make people understand what it is to move，” said David Belle，the cofounder of parkour(跑酷)．
Do you love running？It is a good exercise，yet many people find it boring. But what if making your morning jog a creative one？Like jumping from walls and over gaps and ground rolls？Just like the James Bond in the movie Casino Royale？Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.
Yes，that's parkour，an extreme street sport aimed at moving from one point to another as quickly as possible，getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city，they may jump over fences，run up walls and even move from rooftop to rooftop.
Parkour can be just as exciting and charming as it sounds，but its participants see parkour much more than that.
Overcoming all the obstacles on the course and in life is part of the philosophy(哲理) behind parkour. This is the same as life. You must determine your destination，go straight，and jump over all the barriers as if in parkour and never fall back from them in your life，to reach the destination successfully. A parkour lover said，“I love parkour because its philosophy has become my life，my way to do everything.”
Another philosophy we've learnt from parkour is freedom. It can be done by anyone，at any time，anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.Parkour has become popular throughout the world because of ________.
| A．its cofounder，David Belle |
| B．the film，Casino Royale |
| C．its risks and tricks |
| D．the varieties of participants |

(2012年江西卷，D)For those who make journeys across the world, the speed of travel today has turned the countries into a series of villages. Distances between them appear no greater to a modern traveler than those which once faced men as they walked from village to village. Jet plane fly people from one end of the earth to the other, allowing them a freedom of movement undreamt of a hundred years ago.
Yet some people wonder if the revolution in travel has gone too far. A price has been paid, they say, for the conquest (征服) of time and distance. Travel is something to be enjoyed, not endured (忍受). The boat offers leisure and time enough to appreciate the ever-changing sights and sounds of a journey. A journey by train also has a special charm about it. Lakes and forests and wild, open plains sweeping past your carriage window create a grand view in which time and distance mean nothing. On board a plane, however, there is just the blank blue of the sky filling the narrow window of the airplane. The soft lighting, in-flight films and gentle music make up the only world you know, and the hours progress slowly.
Then there is the time spent being "processed" at a modern airport. People are conveyed like robots along walkways; baggage is weighed, tickets produced, examined and produced yet again before the passenger move again to another waiting area. Journeys by rail and sea take longer, yes, but the hours devoted to being "processed" at departure and arrival in airports are luckily absent. No wonder, then, that the modern high-speed trains are winning back passengers from the airlines.
Man, however, is now a world traveler and cannot turn his back on the airplane. The working lives of too many people depend upon it; whole new industries have been built around its design and operation. The holiday maker, too, with limited time to spend, patiently endures the busy airports and limited space of the flight to gain those extra hours and even days, relaxing in the sun. Speed controls people's lives; time saved, in work or play, is the important thing — or so we are told. Perhaps those first horsemen, riding free across the wild, open plains, were enjoying a better world than the one we know today. They could travel at will, and the clock was not their master. What does the writer try to express in Paragraph 1?
| A．Travel by plane has speeded up the growth of villages. |
| B．The speed of modern travel has made distances relatively short. |
| C．The freedom of movement has helped people realize their dreams. |
| D．Man has been fond of traveling rather than staying in one place. |
How does the writer support the underlined statement in Paragraph 2?
| A．By giving instructions. |
| B．By analyzing cause and effect. |
| C．By following the order of time. |
| D．By giving examples. |
According to Paragraph 3, passengers and turning back to modern high speed trains because ________.
| A．they pay less for the tickets |
| B．they feel safer during the travel |
| C．they can enjoy higher speed of travel |
| D．they don't have to waste time being ‘processed’ |
What does the last sentence of the passage mean?
| A．They could enjoy free and relaxing travel. |
| B．They needed the clock to tell the time. |
| C．They preferred traveling on horseback. |
| D．They could travel with their master. |
What is the main idea of the passage?
| A．Air travel benefits people and industries. |
| B．Train travel has some advantages over air travel. |
| C．Great changes have taken place in modern travel. |
| D．The high speed of air travel is gained at a cost. |

Researchers are now using three-dimensional, or 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.
Surgeons regularly use digital images to explore the heart in close detail. But no two human hearts are alike. This led Matthew Bramlet to create exact heart models from those images. Dr. Bramlet is a pediatric or children's heart expert at the University of Illinois College of Medicine. He says the 3-D models show information he cannot get any other way.
A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model, in his words, "to understand the anatomy(解剖) for the first time."
Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster or clay form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail.
Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations.
Matthew Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.Researchers use three-dimensional, or 3D printing to__________.
| A．create models of the human heart |

Many areas of cropland in Bangladesh(孟加拉国) are becoming unfit for farming. The land is becoming salty. It is a big problem for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.
Farmers in the country are learning to grow vegetables in so-called "vertical gardens." The soil in these gardens is better because heavy rains have removed much of the salt.
A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain.
The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.
Villagers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This "vertical tower" measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12-$13 to build.
The village of Chandipur is in southwestern Bangladesh. Pumpkins and other gourds(葫芦) grow on vines on top of small homes. The vegetables get the food they need from soil placed in containers on the ground.
Shobitha Debna is a 35-year-old farmer in the village. Her garden space is very small. But she is able to grow hundreds of kilograms of vegetables each season.
She says she grows gourds, including pumpkin, as well as green beans, red amaranth, beets, carrots, cauliflower and more.
Ms. Debna depends on the vegetables to earn money. She makes a few dollars a day.
This kind of farming is new in Chandipur. But it may spread across the country.The reason why cropland is becoming unfit for farming is that________.
| A．the soil has been polluted |
| B．more and more land is used for planting trees |

| D．there is too much rain |
Why the soil in vertical gardens is better_______?
| A．because there is much less salt in the soil |
| B．because there is much salt in the soil |
| C．because there is enough water in the soil |
| D．because there is many nutrients in the soil |
From paragraph 4, we can learn that_______?
| A．vegetables with long roots grow in the sides of the containers |
| B．vegetables with short roots grow out of the small holes in the sides of the containers |
| C．vegetables with short roots grow on top of the container |
| D．vegetables in vertical gardens are not productive |
