    It’s 10:30 p.m., and 11-year-old Brandon Blanco is sound asleep at home. Suddenly, a loud noise wakes him up. Naturally, Brandon reaches for his cell phone. He blinks twice, and the message on the screen becomes clear: “R U awake?”
    But the late-night text does not annoy Brandon. He gets frequent messages and calls, even after bedtime. And he can’t imagine life without them. “If I didn’t have a cell phone, I wouldn’t be able to talk to my friends or family as often,” he told the Kaiser Family Foundation.
    Brandon’s use of technology doesn’t stop there. He also has a computer, a TV and three video-game consoles（控制台）in his room. With so many devices, it is no surprise that when he is not at school, he spends nearly every waking minute using one or more of these devices. Brandon is hardly alone. According to a recent study by TFK, kids aged 8 to 18 are spending more time than ever before using electronic devices. How much time? More than seven and a half hours a day on average, the study found. That’s about an hour more than just five years ago.
    The jump is the result of a huge explosion in mobile devices, says Victoria Rideout, the lead author of the study. “These devices have opened up many more opportunities for young people to use media, whether it’s on the bus, on the way to school or waiting in line at the pizza parlor,” says Rideout.
    Often, kids multitask, or use more than one device at a time. “If you’ve got a chance to do something on your computer and take a phone call and have the TV on in the background, why not?” Media expert Cheryl Olson says. Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out with friends. “It’s a matter of balance,” says Olson.
    Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. “It’s important to make sure that you can stop and concentrate on one thing deeply,” says Rideout.
    With new and exciting devices hitting stores every year, keeping technology use in check is more important than ever. “Kids should try,” adds Rideout. “But parents might have to step in sometimes.”
    【小题1】It can be learned from the text that _________.

    A．many teenagers lack friends in their middle school
    B．kids have too many electronic devices to choose from
    C．Brandon feels annoyed about his late-night message
    D．Olson is against teenagers’ using mobile phones
    【小题2】Which of the following is an example of multitasking?
    A．Watching TV when using the computer.
    B．Talking on the phone when lying on the sofa.
    C．Playing video games after having lunch.
    D．Listening to loud music while relaxing.
    【小题3】The underlined phrase “in check” in the last paragraph can be replaced by _________.
    A．in orderB．in storeC．in controlD．in sight
    【小题4】According to the text, Victoria Rideout would probably agree that kids should ______.
    A．do homework while watching TV
    B．have less homework
    C．spend more time on homework
    D．do homework in a place without disturbance

    For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).

    But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.

    The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.

    Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.
