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． |
One day, when I was working as a psychologist in England，an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. “This boy has lost his family，” he wrote. “He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help？”
I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn't have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically.
The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon—in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.
Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?
“Perhaps he simply needs someone to share his pain with，” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.
“It's your turn,” he said.
After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.
Maybe I gave David something. But I also learned that one—without any words—can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.When he first met the author, David ________．
| A．felt a little excited | B．walked energetically |

Teaching is more than leadership. Some of the teacher’s time and effort is directed toward instruction, some toward evaluation. But it is the teacher as a group leader who creates an effective organizational structure (结构) and good working environment so that instruction and evaluation activities can take place. A group that is totally disorganized, unclear about its goals, or constantly fighting among its members will not be a good learning group. The leadership pattern includes helping to form and maintain a positive learning environment so that instruction and evaluation activities can take place.
On the first day of class, the teacher faces a room filled with individuals (个体). Perhaps a few closely united groups and friendships already exist. But there is no sense of group unity, no set of rules for conduct in the group, no feeling of belonging. If teachers are successful leaders, they will help students develop a system of relationships that encourages working together.
Standards and rules must be set to keep order, make sure of justice and protect individual rights, but do not contradict school policy. What happens when one student hurts another’s individual rights? Without clear regulations agreeable to the students and teachers, the classroom can become chaotic. Students may break rules they did not know existed. If standards are set without participation from the class, students may spend a great deal of creative energy in destroying the class environment or finding ways to break rules.
No matter how skillful the teacher is in uniting students and creating a positive atmosphere, the task is never complete. Regular maintenance is necessary. Conflicts arise. The needs of individual members change. A new kind of learning task requires a new organizational structure. Sometimes outside pressures such as holidays, upcoming tests or sport competitions, or family troubles cause stress in the classroom. One task for the teacher is to recreate a positive environment by helping students deal with conflict, change, and stress. The underlined word “maintain” in Para.1 probably means_______.
| A．conserve | B．build | C．recreate | D．evaluate |
According to the author, the teacher should _______.
| A．free students from outside pressures |
| B．set the standards and rules on his own |

| A．rules cannot be changed once they’re formed |
| B．outside pressures may not cause tension among students |
| C．if the teacher well unites his students, he then will finish his task |
| D．if rules are not acceptable both to students and teachers, the classroom can be a mess |
What is the author’s main purpose of writing the passage?
| A．To provide information for teaching. |
| B．To show the importance of teaching a class. |
| C．To study the teacher’s behavior in the classroom. |
| D．To compare the teacher’s behavior with the students’ in class. |
Once I invited a group of friends round to my house, telling them that I was going to record their speech. I said I was interested in their regional accents, and that it would take only a few minutes. Thus, on one evening, three people turned up at my house and were shown into my front room. When they saw the room they were a bit alarmed, for it was laid out as a studio. In front of each easy chair there was a microphone at head height, with wires leading to a tape-recorder in the middle of the floor. I explained that all I wanted was for them to count from one to twenty. Then we could relax and have a drink.
I turned on the tape-recorder and each in turn seriously counted from one to twenty in their best accent. When it was over, I turned the tape-recorder off and brought round the drinks, and for the rest of the evening there was general cheerful conversation—interrupted only by the fact that I had to take a telephone call in another room, which unfortunately lasted some time.
Or at least that was how it would appear. For, of course, the microphones were not connected to the tape-recorder in the middle of the room at all but to another one, which was turning happily away in the kitchen. The participants, having seen the visible tape-recorder turned off, paid no more attention to the microphones which stayed in front of their chairs, only a few inches from their mouths, thus giving excellent sound quality. And my lengthy absence meant that I was able to obtain as natural a piece of conversation as it would be possible to find.
I should add, perhaps, that I did tell my friends what had happened to them, after the event was over, and gave them the choice of destroying the tape. None of them wanted to—though for some years afterwards it always seemed to be my round when it came to the buying of drinks. Linguistic research can be a very expensive business.The writer asked his friends to count from one to twenty because _______.

| B．he wanted to find out whether the tape recorder was working |

The writer went into another room to ________.

| B．stay away from too much drinking with his friends |
| C．bring a telephone into the front room |
| D．answer a long distance phone call |

Oprah Winfrey, born in 1954, is all American talk show host, best known for her multi-award-winning talk show. She is also, according to some assessments, the most influential woman in the world. It's no surprise that her endorsement(认可)can bring overnight sales fortune that defeats most, if not all, marketing campaigns. The star features about 20 products each year On her “Favorite Things” show. There’s even a term for it: the Oprah Effect.
Her television career began unexpectedly. When she was 16 year old, she had the idea of being a journalist to tell other people’s stories in a way that made a difference in their lives and the world. She was on television by the time she was 19 years old. And in 1986 she started her own television show with a continuous determination to succeed at first.
TIME magazine wrote, “People would have doubted Oprah Winfrey’s swift rise to host of the most popular talk show on TV. In a field dominated by white males, she is a black female of big size. As interviewers go, she is no match for Phil Donahue. What she lacks in journalistic toughness, she makes up for in plainspoken curiosity, rich humor and, above all understanding. Guests with sad[stories to tell tend to bring out a tear in Oprah’s eye. They, in turn, often find themselves exposing things they would not imagine telling anyone, much less a national TV audience.”
“I was nervous about the competition and then I became my own competition raising the bar every year, pushing, pushing, pushing myself as hard as I knew. It doesn't matter how far you might rise. At some point you are bound to fall if you’re constantly doing what we do, raising the bar. If you're constantly pushing yourself higher, higher the law of averages, you will at some point fall. And when you do, I want you to know this, remember this: there is no such thing as failure. Failure is just life trying to move us in another direction” as Oprah addressed graduates at Harvard on May 30, 2013.The Oprah Effect refers to _______
| A．the effect on a business | B．the power of Oprah’s opinions |
| C．the impact on talkshows | D．the assessment of Oprah’s talk show |
What can be inferred about Oprah’s television career?
| A．She once gave up on her choice |
| B．Her swift success has been expected. |
| C．It lives up to her parents’ expectation. |
| D．She must have been challenged by white males. |
The message from Oprah to graduates at Harvard is that _______.
| A．success comes after failure |
| B．failure is nothing to fear |
| C．there is no need to set goals too high |
| D．pushing physical limits makes no sense |
Which of the following best describes Oprah Winfrey?
