我国北方有一种生态农业模式，是在温室里把种植农作物和养殖动物结合起来，实现优势互补，收到了良好的经济效益．关于这种生态模式的说法中，不正确的是（　　）

    ①比较文明是个新课题。之所以新，是因为我们刚开始习惯以世界为关心对象。

    ②比较文明的目的是理解文明。个体研究固然有其合理性，然而无视整体的结果一定是盲人摸象。比较研究是整体下的个体与个体的比较，或个体与整体关系的钩沉。从中国的视角来看世界以及从世界的维度理解中国，是出和入、间离和沉浸的关系，是辩证发展的关系，是螺旋上升的关系。有了“从周边看中国”，对中国的认识才会更完整，更接近真实。

    ③比较文明研究是有伦理的。有些比较无益甚或有害，伦理就是约束。比如“汤显祖”和“莎士比亚”，比人生轨迹，没什么好比，但在创造文学形象的维度比较，不但有益而且必需。有些比较无意义，并非学术前提出了问题，而是回答不了“然后呢”这个问题。

    ④比较文明是有方法的。文明离不开人，物作为文明的见证，也很重要。物是实实在在的，罐就是罐，盆就是盆。当年瑞典人安特生在西北见到彩陶就一眼看出它和世界各地彩陶文化的联系，后来我们批判“中国文明西来说”，把世界维度下的中国彩陶变成了中国自己的彩陶。彩陶西来与否和中国的正当性其实毫无关系。

    ⑤文明比较有宏观和微观两个层面。制度比较属于宏观的文明比较。因为有文献，制度很容易比较，但也有缺陷，一是文献资料有太多不可信的成分。二是制度大概未必属于文明的范畴，它更像是文明的副产品，其本质是制度的制定者对受制度约束的人实践优势的工具。如今的民主制度在柏拉图那里未必多么理想，同理，当年的“君臣父子”也未必全然“反动”。

    ⑥微观的文明比较主要在这两个范畴：从具体的物到生活方式、思维方式；从核心价值观念到具体的物。前者受时空约束，它是已然的，找出异同作出解释，能改变的很有限。后者则有超越时空的启发和引领意义：罗马人的沃伦杯与两千年后的中国电影《霸王别姬》同样在叙述欲望与爱的故事；静穆而伟大的希腊石头与北齐佛造像都是人类最伟大的气质与精神的外化，存在于所有不朽的艺术品之中；敦煌的鹿王本生与圣艾格尼斯杯主题都是牺牲……

    ⑦文明的比较，核心在于解释文明的演进，以达成文化认同与自信。有个就叫“文明”的游戏，选哪个来玩都可以，结果只和操作有关，真实的文明也是。现在讲多元，不是否认进步与落后，而是相信比之于可以弥合的差距而言，基因更重要，我们需要一个色调丰富的文明体系。

    Is your TV connected to the Internet? What about your chair, or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called "Internet of things".

    The Internet of things may be coming sooner than you think. Earlier this year, Samsung CEO spent a lot of time talking about the Internet things. He said that three years from now, every Samsung product will be part of the Internet of things, no matter whether it's a remote control or a washing machine.

    So, how do household objects that are part of the Internet of things work? Well, think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold.

    An Internet-connected camera could help people feel safer in their homes. It can know people's faces and has an infrared sensor（红外传感器）, so even if it's dark it can see when someone passes by and send you a message on your smart-phone to let you know who's there. If the person is someone you don't know, it can tell you that, too.

    But according to MIT Technology Review, whether companies are connecting dog food bowls or safety systems to the Internet, there may be some problems. For example, many early connected-home objects don't have much built-in security, which means they could be hacked（攻击）. Moreover, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2015.

    So, picture this: you enter your home. The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think.
