DVD for Rent
1 A pay-for-play system for video DVD will emerge by summer as an alternative, and possibly a competitor, to the DVD format currently available.
2 The new system, called Digital Video Express (Divx), operates like a DVD player, except for the specially coded discs. These will cost $5 for initial viewing over a 48-hour period and can be viewed again for additional fees and even purchased for unlimited viewing.
3 Divx combines the service of a video rental (出租的) store with the operation of a pay-per-view TV channel. Unlike a rented videotape, though, the Divx disc needn't be returned. Customers can retain the disc for replay in the future at an additional fee, or simply throw it away.
4 Subsequent plays, or the purchase of unlimited-viewing rights, are billed to the customer's Divx account and charged to a credit card. The player's built-in mernory keeps track of all Divx plays, and sends this information by toll-free phone modem (调制解调器) to the Divx record-keeping centre. Each Divx disc and player has a unique identification code, so the system knows which discs have been played and where.
5 Some Divx discs could be converted for unlimited play at a price likely to be lower than buying a conventional DVD． Others, called Divx Gold, would be sold from the beginning for unlimited play without further charge. Although conventional DVDs will run in a Divx player, conventional DVD players will lack the decoding (解码) and communications ability to play Divx discs. Divx players will be offered by Panasonic, RCA, and Zenith.
6 About 100 discs will be available initially from Disney, Dreamworks, Paramount, and Universal, growing to 500 titles within a year. Other film makers have yet to adopt the Divx system, which is owned by retailer Circuit City, the 350-store electronics chain that bankrolled (提供资金)its development.

A Dolphin and an Astronomer
One day in 1963, a dolphin named Elvar and a famous astronomer, Carl Sagan, were playing a little game. The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. Sagan was standing on the edge of one of the tanks where several of these friendly, highly intelligent creatures were kept. Elvar had just swum up alongside him and had turned on his back.
The dolphin wanted Sagan to scratch his stomach again, as the astronomer had done twice before. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water and made a sound just like the word 'more'. The astonished astronomer went to the director of the institute and told him about the incident.'Oh, yes. That's one of the words he knows,' the director said, showing no surprise at all. Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and much further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a 'language', in the real sense of the word？ Scientists don't agree on this.
A language is not just a collection of sounds, or even words. A language has a structure and what we call a grammar. The structure and grammar of a language'help to give it meaning. For example, the two questions 'Who loves Mary？' and 'Who does Mary love？' mean very different things. If you stop to think about it, you will see that this difference doesn't come from the words in the question but from the difference in structure. That is why the question 'Can dolphins speak？' can't be answered until we find out if dolphins not only make sounds but also arrange them in a grammatical order which affects their meaning.
