&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.

Successful Time Management A The secret of avoiding work pressure is thinking ahead. Every day you need to review your progress towards objectives and decide how you can best use the time available to make further progress. You may find this is best done at the start of your working day but some people prefer to have a planning session just before they finish. Whichever you select - and you may need to experiment to find what suits you best- find some way of fitting the activity into your schedule. Never say, '1 don't have time to plan today'. B Managers at all levels occasionally find they have taken on more than they can cope with. This is not a crime, but you must examine the reasons for such a situation and then plan a course of action. Until the problem is resolved, most of your time and energy will go into worrying about the situation and you will feel unmotivated. Think too about how to prevent it happening again. This may require you to be firm and avoid agreeing to more than is realistic. C If a review of your working practices shows that you are too much of a perfectionist, do something about this. Modern definitions of quality refer to 'fitness for purpose'. If you bear this in mind, you may find it easier to persuade yourself to settle for an acceptable level of quality rather than perfection. When thinking about objectives and planning how to achieve them, consider how thoroughly you need to do something in order to meet your requirements. Unless you have spare time, do not spend extra hours on an activity in an effort to cover absolutely everything. D If your review of a period of time shows that you are spending time on things that are not really necessary or important, then think hard about whether you can afford this time. Many people file unnecessary papers and attend endless, unproductive meetings. Even top managers can be guilty of misdirecting their efforts by supervising subordinates too closely or failing to delegate. If you question the necessity of certain work, you may find it easier to avoid these misdirected efforts and this will better inform. your planning in the future. In order to complete a task well, it may not be necessary to deal with every detail.

&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.

A．Cutting newspapers is a hard job. B．When you are caught in a fix, you have met two good things. C．There must be a way that is better than the other. D．You should maintain a positive attitude towards your choice.
