SECTION B PASSAGES

Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.

听力原文： Each year car theft costs us about ￡300 million, and burglary sets us back by another ￡150 million.

Yet the police reckon that one car in five is left unlocked, or with windows open, or with expensive goods temptingly on display. It is estimated that over 60% of homes still do not have any window locks, although that's better than a few years ago when it was near 90%.

These facts illustrate a basic truth. The truth is that most criminals are on the lookout for a soft touch. They are not hardened "professionals" who set out with particular targets in mind, but young, inexperienced or unsophisticated. What they're looking for is a house or car that will let them get in, get what they want and get away quickly. In short, an easy opportunity.

Many of these opportunities can just as easily be removed, by fitting and using locks, or by taking other very simple precautions. And if we can foil small-time criminals with modest individual effort and cost, how much more could be achieved by working together in Neighborhood Watches？ Or in other local activities involving police, councils, businesses, voluntary groups and schools？ More radically still, what might we see if more systematic effort was made to design anti-crime features into cars, houses and estates？

This is not a pipe dream; it's already happening.

A basic premise of OGSA is that everything is(71)by a service: a network enabled entity that(72)some capability through the exchange of messages. Computational resources, storage resources, networks, programs, databases, and so forth are all(73). This adoption of a uniform. service-oriented model means that all components of the environment are virtual. More specifically, OGSA represents everything as a Grid service: a Web service that conforms(74)a set of conventions and supports standard interfaces for such purposes as lifetime management. This core set of consistent interfaces, from which all Grid services are implemented,(75)the construction of hierarchical, higher-order services that can be treated in a uniform. way across layers of abstraction.
