Passage One
| American consumers like convenience very much. During the last 50 years, there has been a dramatic increase in such labor-saving devices as automatic washing machines, clothes dryers, dishwashers, food processors, microwave ovens, garbage disposals and power lawn mowers. Today, all of these and many more, are found in a typical suburban home. These labor-saving devices are designed to reduce the time spent on housework. However, the time that Americans save is quickly spent on other activities. The American desire for convenience also created the concept of fast-food restaurants, found in every city and almost every small town in the United States, and now exported all over the world. These fast-food restaurants, such as McDonald’s and KFC, serve sandwiches, salads, fried chicken, seafood, and other food to hurried customers in five minutes or less, often at a drive-up window. There are also a wide variety of restaurants that will deliver Chinese food, pizza, and other dishes to people’s homes in about a half-hour. In many areas there are "take-out taxis" that will deliver food from the menus of 20 or 30 different restaurants for a small charge. For those who prefer to prepare their food at home, American grocery stores are full of convenience foods that are packaged and ready to cook or even precooked. Like microwave ovens and dishwashers, fast-food and take-out restaurants are convenient because they save the American consumer time that would otherwise be spent fixing meals or cleaning up. More than half of all the women in the United States are currently employed. This includes mothers with children under the age of 18. More than half the women with little children under the age of six hold jobs. Sixty-eight percent of the women who have school-age children are employed. Families with working mothers need all the time-savers they can get. Thus, the conveniences that Americans desire reflect not so much a leisurely lifestyle as a busy lifestyle in which even minutes of time are too valuable to be wasted. Alexis de Tocqueville was one of the first to see in this a curious paradox (自相矛盾) in the American character. He observed that Americans were so busy working to acquire comforts and conveniences that they were unable to relax and to enjoy leisure time when they had it. Today, many Americans have what one medical doctor has called "the hurry sickness". |
It is implied in the passage that ______.
A．fast food is not as nutritious as home-cooked food
B．fast food restaurants are more popular than take-out restaurants in the U. S.
C．most of the cooking at home is done by women
D．more men than women prefer eating convenient food

网络改变世界，文化助力未来
材料一：2015年12月16日，第二届世界互联网大会在浙江乌镇举行，大会的主题是“互联互通、共享共治——构建网络空间命运共同体”。“互联互通、共享共治”，是精准把握互联网规律具有全球视野的中国理念；新提“构建网络空间命运共同体”，则彰显出网络空间治理的中国主张、中国智慧和中国担当。
材料二：乌镇因互联网而更加驰名中外，互联网因乌镇而更加古香古色。乌镇的闻名得益于它一直努力打造文化名镇，不断探索古镇保护开发的新模式，注入新的元素，不断提升保护开发的品质和内涵，创造了古镇保护开发的“乌镇”模式。今天的乌镇，不仅保留了典型的江南水乡特征，而且也比较完整地保存了原有水乡古镇的风貌和格局，传承着中国古典民居“以和为美”的人文思想，呈现着江南水乡古镇的魅力。同时乌镇也紧跟时代和世界的步伐，不断创新，在文化方面推出了一系列漂亮的动作：如建设乌镇大剧院，改造古戏台，打造乌镇文化创意区等。如今的乌镇，传统与现代的有机结合凸显了独特的魅力，先进的世界文明成果与悠久的中华文化交流融合，开拓了新境界。
材料三：2015年10月5日，屠呦呦获得诺贝尔生理学或医学奖，她成为首获科学类诺贝尔奖的中国人。“中国神药”--青蒿素因屠呦呦而家喻户晓。研究初期，屠呦呦团队从系统整理历代医籍、本草入手，收集二千多种方药，并筛选出了最有希望的青蒿，但实验结果并不十分理想。之后，他们查阅中医药典籍《肘后备急方》，从“青蒿一握，水一升渍，绞取汁服，可治久疟”等文字记载中获得灵感，在尝试用水、乙醇等方法提取失败后，最终采用沸点较低的乙醚提取青蒿，先驱性地发现了具有100%抗疟作用的青蒿素。后来，他们通过元素分析、光谱测定等西医常用的技术手段，明确了青蒿素是一种全新的抗疟药，打破了过去认为“抗疟药必须含氮杂环”的断言。针对青蒿素成本高、难以根治疟疾等缺点，他们又创制出临床药效高于青蒿素10倍的双氢青蒿素。世界卫生组织评价“青蒿素是目前世界范围内治疗恶性疟疾的唯一真正有效的药物”。
从经济生活角度分析，“构建网络空间命运共同体”对中国经济的积极影响。
