Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
The chant of "digital, digital, digital" continues to grow in volume worldwide. Digital cameras, digital video camcorders (摄像放像机), video CD Players, DVD, cellular phones, and a host of computer peripherals (外围设备) are moving the trend along at a breathtaking rate. For the average person, it may seem like a remote and puzzling phenomenon meant only for the technologically adept.
Virtually every aspect of our lives could be affected by the digital revolution. Here is a hypothetical scenario (设想) to show the possibilities: A real estate agent in Seattle uses a digital still camera to take some pictures of a house she's trying to sell. She transfers them to her computer, digitally retouches and enhances them, and posts them on her company's Internet Web site. In Singapore, a buyer sees the pictures and asks via electronic mail for more information. The agent replies via e-mail and attaches the text and a digital video clip to her message. Later the buyer flies to Seattle, inspects the property, and seals the deal.
One of the biggest marketing surprises of the current age is the digital still camera. Once prohibitively expensive, these cameras have radically dropped in price while gaining in resolution (分辨率) and other features. Although they often resemble traditional cameras, they don't use film. Instead, they store images on either a small removable memory card or on the memory chip inside the camera.
The beauty of digital photography is that while you'll spend relatively more for a digital camera, you'll save a lot on film processing costs, because there aren't any. You can also discard digital pictures and keep shooting. Better yet, you can use software to enhance or alter the image. In quality, the images consumer level digital cameras produce do not compare to ones you'd get from a 35mm camera. For the most part, though, digital photos are meant to be viewed on a computer monitor, and so their resolution is more than acceptable. In a word where the speed at which you distribute information often means the difference between success and failure, and immediacy supersedes quality in importance, many people are finding a sue for digital camera.
From the first paragraph we know the average person thinks ______.
A.the digital age is far away
B.digital is too complicated for him
C.digital age is terrifying
D.both A and B
