F 5. Burglary occurs more often in the morning than at night because there is no one at home. (Daylight is no protection: Some 36 percent of all break-ins occur during the day. A burglar we'll call Tony has looted over 250 homes - \mornings. \are at work.\
F 6. The rate of the ransacked houses with alarms is only half of those without them. (Studies indicate that houses with alarms are struck only one-sixth to one-third as often as those that don't have them.)
F 7. One of the tips is that it is necessary to leave your transistor radio on while you are away during the day.
(It is not mentioned in the passage.)
T 8. If your home is properly insured, you will be well compensated when you do suffer a loss. (Make sure your home is properly insured so you can recover quickly if you do suffer a loss.)
Exercise D After-listening Discussion
Directions: Listen to the passage again and discuss the following questions.
Because last year, over two million US households discovered just how devastating a burglary can be. The thieves' annual take is $3.5 billion. Burglary is not just a crime against property. According to government statistics compiled from 1973 to 1982, in fully 13 percent of break-ins crooks encountered someone at home; nearly a third of those confrontations ended in assault; and ten percent of the violent crimes
committed were rapes.

Airline Internet Technology The Internet is changing the way business is done in many industries. Linda Cashdan takes a look at a new Internet technology designed to increase both efficiency and productivity at US airports.
A mammoth jet plane empowered by the latest technology rises effortlessly into the sky with its cargo. Less visible is the tremendous ground effort that made that take-off possible - the airport baggage, food service, and fuel crews, the ticket checks, loading and safety operations.
Dave Laufer, the head of Laufer Aviation, Israel's leading ground handling company, says most people do not realize how complicated such ground operations are - or how chaotically they are handled at many airports.
In hopes of remedying this, Laufer Aviation is one of several airline companies testing a new Internet technology designed to eliminate the paper and synchronize the information.
Niv Schwartz, the head of AirSphere, the firm that designed the technology, says it consolidates all information in one place and makes that information available on individual computers to all the companies involved.

Researchers in Australia say they have developed a way to dramatically increase the storage capacity of a DVD-size disk.
If it all works out you could watch a different movie almost every night of the year, and never have to change disks.
James Chon and colleagues at Swinburne University of Technology say the new idea takes a multi-layer disk, where bits of data are stored in two surface dimensions
plus depth, and combines it with coding for two other factors.
“Individual bits can have different colors of encoding schemes and have three more additional layers, so to speak. Now we can add further another dimension in recording, which is the polarization encoding, one horizontal and one vertical. So in total, we can have six additional channels in one recording bit.”
In this five-dimension configuration the disk could hold about 1.6 terabytes of data—about as much as 300 DVDs.
Dr. Chon says a prototype is still three to five years away. He describes the new super-dense storage disk concept this week in the journal Nature.
