It's no secret that most busy American mothers use the TV set   [21]   （介詞）a live-in babysitter. In some families the TV holds a child's attention for half   [22]   （冠詞）hour or two while mom works on dinner; in others it is the child's constant daytime companion. Is there any harm in this?

　　Debate on the question is very hot, and periodically research is published   [23]   （show）that TV reduces attention space, makes children upset or causes them to be violent. In today's cartoon David Horsey makes   [24]   of （短語動(dòng)詞）the show-off of "children's TV". It is said  [25]   （從屬連詞） the special programing supposedly uses entertainment to help youngsters to learn to read and take their  [26]   （數(shù)詞） steps in the big, diverse world outside their family. But what do children really get from this programming?

　　Horsey's suspicion is   [27]   （從屬連詞）children's programming chiefly turns kids into TV addicts(上了癮的人), not into readers or happy mixers. The kids, still at their early age, are attracted by the figures on the screen. "Can you say TV?" The  [28]   （soon） the kid learns the word, the more effectively he can remind his mother to turn on the TV.

　　A child hooked on TV tends  [29]   （構(gòu)成非謂語動(dòng)詞） fix his eyes on commercial advertisement, and there are plenty of those targeting children of all ages. Thus, at the very least, mom tries to search for a certain way to make the kids quiet and peaceful , hence changing a child    [30]   （介詞） an American shopper all day long. Spending too much time on the tube will have an ill effect on the kids.

PITTSBURGH – For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.

The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots， he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.

Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn’t know of one that could climb pipes.

The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick(操縱桿). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.

Built from lightweight materials, the robots are about the size of a human arm or smaller.They can sense which way is up, but are only as good as their human operators, Choset added.

Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.

“It just allows us to do something we’ve ot been able to do before,”Stover said, “We needed them yesterday.”

He said sniffer dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged building.

Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.

Choset said the robots may not be ready for use for another five to ten years, depending on funding.
