&8226;Look at the statements below and the information on outdoor advertising on the opposite page.
&8226;Which section (A, B, C, or D) does each statement 1-7 refer to？
&8226;For each statement 1--7, mark one letter (A, B, C, or D) on your Answer Sheet.
&8226;You will need to use some of these letters more than once.
A
The cost-effectiveness and flexibility offered by large-format digital imaging has also helped diversify the number of out-of-home media. Out-of-home was a concept that didn't have a name until digital technology gave it one. Instead of hand- painting a bus or shelter, a self-adhesive graphic can be digitally imaged in a short amount of time and applied with relative ease. Advances in the durability and weatherability of inks and vinyl substrates keep the images looking sharp for a longer time.
B
Other technologies contribute to improvements in outdoor advertising. Satellite lighting systems allow outdoor companies to remotely adjust billboard lighting to change with seasons and daily light differences. For instance, lights can be programmed to turn off at the end of an advertiser's contract, while two-way communication lets outdoor companies know when there is no power.
C
Another electronic device barcode-identification tracks an advertiser's campaign from poster production through shipping, display and removal. In this way, advertisers can verify the status of their campaign through on-line communication with the outdoor companies. Similarly, computer-mapping systems help advertisers combine demographic and geographic market research data with outdoor locations to determine the best place to advertise.
D
Global positioning systems (GPS) make up another technology that enables the outdoor industry to determine display locations. Data is gathered with a hand-held GPS receiver that receives radio signals from satellites. The data is then put into mapping database systems that visually position billboards and other out-of-home advertising displays at that location. In this way, advertisers can test creative designs at specific locations from a computer before they commit to them.
Lighting system of billboard changes seasonally, which is remote-control.

&8226;Look at the statements below and the information on future home on the opposite page.
&8226;Which section (A, B, C, or D) does each statement 1--7 refer to？
&8226;For each statement 1--7, mark one letter (A, B, C, or D) on your Answer Sheet.
&8226;You will need to use some of these letters more than once.
A
It's the space where commodities traders turn into couch potatoes and kids spend every waking moment from the terrible twos to the terrifying teens. Whatever you want to call it--the living room, the family room, the playroom--it's now the most wired room in the house, even more so, surprisingly, than the home office. So it's about time you got some R&R (Rest and Relaxation) payback from all that technology.
B
Despite many changes in the past few decades, we're essentially doing the same things in the family room we've always done. These include watching TV and movies, listening to music, and communicating with friends. But now we've gone hi-tech. The capabilities and quality of the devices we use today have improved dramatically, and there's much more to come. Parts of your future living room are currently well-defined and developed, but hooking them all up into a cohesive whole is still like piecing together a jigsaw puzzle.
C
In recent years, TVs have become bigger and more beautiful. But we're still paying a high price for the size and beauty. Take, for example, Toshiba's 65-inch Theater Wide HD Projection TV, which is big enough to make you feel like you're really in a movie theater. As it costs almost $ 8, 500, you could practically hire some actors to perform. in your living room for less. But you're paying for the size and picture quality of a projection TV, as well as future-proofing support for digital High-Definition TV.
D
The great thing about life in the 21st century is how much easier when you get home. In Tokyo the folds at Panasonic have built a mockup of what they call "the house of the future". In the future, it's gonna be video mail and starts when you do a fingerprint analysis to let the computer know you're home. Sensors then note your presence, turn on the lights and set each room's temperature to your preference, or fire up the 500-channel, 50-inch plasma TV, which can store a hundred hours of TV programs in the main home computer.
What we have done in the living room will be related closely to each other in the future.
