回归分析法

At the beginning of the twentieth century, North American society held, as an ideal, the Nuclear Family. This presumably perfect residential, social, and economic unit consisted of an adult male, an adult female and their minor children. This structure was thought to be stable and long lasting.
However, a few decades later, the structure of that ideal family was being altered radically even while it was being touted as the structure to be aimed for. Popular magazines bemoaned the loss of the Nuclear Family and its replacement with inferior forms.
There are a number of factors that are acting in concert to apply pressure on the Nuclear Family and generate a variety of new structures. Some of these are:
The definition of marriage has changed somewhat in that few people now consider it to last "until death do us part". The concept of monogamy (the marriage of one man and one woman) has been modified to a form now referred to as serial monogamy (the marriage of one man and one woman at a time). This reflects the increasing equality of women and men in terms of economic advantage and the recognition that many women no longer depend on men for their survival. Women are acquiring independence and have become empowered to make their own choices. With this independence, the need to form a relationship with a man becomes less important. This change embodies the concept that the marriage is temporary and can be terminated by either partner at any time. Associated with this, of course, is the relaxation of the divorce laws and the significant reduction of the shame that had one time been attached to divorce.
The economy of North America has resulted in a two-tier system of a few rich who control most of the resources and a large portion of the population who control almost none of the resources. Because of this, many couples are forced to have both partners with full-time jobs outside the home. There are unintended byproducts of the need for a double income. The most important of these is the replacement of a mother-oriented socialization of children to a "stranger-oriented" socialization system reflected in the growth of the childcare industry. Also, either partner is financially able to end the marriage without significant hardship.
The combination of these changes will in the coming decades have a profound effect on the structure of the family of North America. As a result, the family will be a fluid, constantly changing structure with variable household arrangements as the norm.

In Paragraph 4, "until death do us part" probably means remaining married ______.

A．until death

B．to the particular person until death

C．to one person at a time

D．until one leaves

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》)

下面几项中，表示“多媒体”优于电话、电视和电脑的特有功能的一项是（）。

A．人们不仅可以听到声音，而且可以看到形象。

B．人们即使相隔万里也能进行双向交谈。
