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.

1.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.

2.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

3.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.

4.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.

When I was an official of a school in Palo Alto, California, Polly Tyner, the president of our board, wrote a letter that was printed in the Palo Alto Times. Polly’s son, Jim, had great difficulty in school. He was classified as the educationally handicapped and required a great deal of patience on the part of his parents and teachers. But Jim was a happy kid with a great smile that lit up the room. His parents knew his difficulties, but they always tried to help him see his strengths so that he could walk with pride. Shortly after Jim finished high school, he was killed in a motorcycle accident. After his death, his mother submitted this letter to the newspaper.

“Today we buried our 20-year-old son. He was killed in a motorcycle accident on Friday night. How I wish I had known that the last time I had talked to him would be the last time. If I had only known that, I would have said to him, ‘Jim, I love you and I’m always so proud of you.’ I would have taken the time to count the many blessings he had brought to the lives of the people who loved him. I would have taken the time to appreciate his beautiful smile, his laughter, and his genuine love to other people.

“When I put all the good things on the scale and try to balance them with all the irritating (恼人的) things such as the radio that was always too loud, the haircut that wasn’t to our liking, the dirty socks under the bed, etc., I find that the irritations really don’t amount to much.

“I won’t get another chance to tell my son all that I would have wanted him to hear, but, other parents, do have a chance. Tell your young people what you would want them to hear as if it may be your last conversation. The last time I talked to Jim was the morning of the day when he died. He called me to say, ‘Hi, Mom! I just called to say I love you. You have to go to work now. Bye.’ That day, he gave me something to treasure forever. ”

If there is any purpose at all for Jim’s death, maybe it is to make others appreciate life more and to tell people, especially family members, that they should take the time to let each other know just how much they care. You may never have another chance. Do it today!
