Disability among the elderly has declined markedly in the United States in the past two decades.

Although these basic facts are well known, their interpretation is not clear. Is the reduction in disability a result of improved medical care, individual behavioral changes, environmental modifications that allow the elderly to better function by themselves, or other demographic changes Will the trend continue, or is it time limited What does the reduction in disability mean for years of healthy life and labor force participation

[填空题]The headline of a newspaper presents the heart of the news in brief form. Because of space limitations head-line writers tend to use short verbs and nouns. Scanning the headlines gives a hasty look at the major news of the day. Headlines are often presented in steps. Each section adds to the news presented in the top headline, If you have only a little time, you may wish to read the headlines and follow up only a few stories you are particularly interested in.
The first paragraph, or lead of a news story answers certain questions that might be asked by a reader. A lead answers some or all of these questions: "Who What When Where Why How " Once again, if you are pressed for time, you can get a great deal of information by reading just the lead.
The news article develops the information presented in the head-line and the lead. News articles are usually written so that paragraphs may be clipped off the end without damaging the story. Since news columns must fit the spac
[单项选择]Animation is older than cinema, indeed almost as old as photography. Niepce made the first still photograph in 1826, just six years before Plateau invented the Phenakistoscope. The Zoetrope appeared just a year later in 1833.These two devices were examples of what today we would call drawn animation, presenting a series of pictures to the viewer in rapid succession to give the illusion of movement. While such toys were highly popular in the nineteenth century, it was not until the birth of cinema at the end of the century that animated films could tell stories.
Before the advent of CGI in the 1980s, animation techniques could be divided into two broad categories-drawn animation and model (or stop-motion) animation. The former involves photographing a series of two-dimensional images, usually drawings but sometimes cut-out shapes, while the latter uses three-dimensional puppets and models. Both techniques developed rapidly in the early years of cinema, with Cohl (" Fantasmagorie"
