题目内容
阅读下面短文，回答以下问题。“多媒体”是近几年才流行起来的新名词，它是融合多种传播媒介的手段于一体的设施，具体来说，就是融合电话、电视和电脑这三种主要传媒的性能于一体，并在原有基础上再衍生出其他相关的新用途的设施。人们通过电话，即使相隔万里也可以双向交谈，但可惜只能听到声音(近十多年来传真机通过电话线可传送图文)，却不能见到谈话人形象；人们在电视机上可以看到图像和听到声音，但只能单向、被动地接受，而不能双向交流；电脑是处理和储存信息的工具。在终端机的荧屏上人们可以看到各种数据和图像。而通过多媒体，既可以接收，也可以发送各种声音、形象、文字、图表和数据。把家庭和企业里的多媒体与全国范围内的企业、商店、银行、学校、医院、 图书馆、电脑数据库、新闻机构、娱乐场所、电视台、会议厅的多媒体连接起来，形成互相交叉的网络，这个网络就是目前美国政府正在着手进行的“信息高速公路”，正式名称是“全国信息基础设施”。这里是借用50年代美国修建了全国高速公路的干线，对加速商品和劳务的流通，推动全国经济发展曾起了巨大的作用之意。具体来说，就是在全国范围内，铺设光导纤维的电缆作为信息流通的主干线(只有新型的光缆才能有这么大的容量)，通过光缆和多媒体， 向全国提供教育、卫生、商务、金融、文化、娱乐等等颇为广泛的服务。(佚名《多媒体》) 适合作本文题目的一项是（）。

No woman can be too rich or too thin. This saying often attributed to the late Duchess (公爵夫人) of Windsor embodies much of the odd spirit of our times. Being thin is deemed as such a virtue. The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently I have been on a diet for the better—or worse—part of my life. Being rich wouldn’t be bad either but that won’t happen unless an unknown relative dies suddenly in some distant land leaving me millions of dollars. Where did we go off the track When did eating butter become a sin and a little bit of extra flesh unappealing if not repellent All religions have certain days when people refrain from eating and excessive eating is one of Christianity’s seven deadly sins. However until quite recently most people had a problem getting enough to eat. In some religious groups, wealth was symbol of probable salvation and high morals and fatness a sign of wealth and well-being. Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat—or even only somewhat overweight—is bad because it implies a lack of moral strength. Our obsession (迷恋) with thinness is also fuelled by health concerns. It is true that in this country we have more overweight people than ever before and that in many cases being overweight correlates with an increased risk of heart and blood vessel disease. These diseases however may have as much to do with our way of life an dour high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem—too much fat and a lack of fiber-than a weight problem. The real concern then is not that we weight too much but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balance diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough It is actually hazardous if those who get or already are thin think they are automatically healthy and thus free from paying attention to their overall life-style. Thinness can be pure vainglory (虚荣). Swept by the prevailing trend, the author ______.
