Article: 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 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...

Article: At the recent O&P Extremity Games, I had the opportunity to observe a new generation of athletes with disabilities who were skateboarding and rock climbing.

When we get and stay active, we will feel better, be able to do more, have healthier bodies, and look better. It is a fact that exercise actually produces energy and builds on itself.

Read the following article and select the best answer. Article: We are always attracted by the sea. From it we can get food, minerals and treasures. For thousands of years, we just sailed on it but couldn't go far under its surface. We want to explore deep into the sea. However, we are not fish. We must breathe, so we can't stay underwater for long. To explore deep water, we face even more dangers and problems. A diver trying to stay underwater for a long time must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a special pipe. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea, so his body is under great pressure. When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to the surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles . The diver is then suffering from a kind of illness. This kind of illness can cause a diver great pains and even kill him. Question: The text is mainly about _ . - special mixture of gases in the deep sea - the problems a diver faces in the deep sea - air pressure under the surface of sea water - a kind of illness that a diver suffers in the sea
