While staying with a family, I found their teenage son, David, aged 16, didn’t share his true feelings with his parents. If his parents were present when I asked him how he felt about things, he would look down or away or say something unrelated such as, "Today, I will go out. "or "Okay, I guess. "However, when we were alone he would open up and tell me how he felt. For example, while sitting at the dinner table, I asked him how he felt about his history class and the teacher. He thought for a moment but said nothing. I thought he was afraid to answer in front of his parents, so later I asked him again in private. He said, "On a scale (级别) of 0-10, it is a big fat zero. He is the most boring teacher I have ever had. "I asked him why he didn’t tell me this earlier. He said it was because his parents didn’t want to hear that. They just wanted to hear that everything was wonderful and they always told him to stop complaining.

This made me think a lot. My belief is that children are born with the desire to share feelings. I also believe they are born with perfect emotional honesty. Unfortunately, such valuable things are disappearing gradually. It really is a great loss, which I believe, will negatively affect both the children’s ability to know about themselves and their success in future relationships.

I see the situation as a missed opportunity, an opportunity for parents to get closer to their children, an opportunity to understand their children and to help them feel understood; however, communication gaps (分歧) have been made. Parents are more interested in "correcting" their children’s ways of expressing themselves than in getting to know their children.

枝蔓状城市——以城市边缘化和信息技术、虚拟技术为特征的后现化城市，将既不会是奴隶社会的“城堡式”城市，也不会是封建社会的“城池式”城市，当然也会与现代工业社会高楼耸立的中心化城市相区别。
在枝蔓状城市布局中，即使是眼下北京绞尽脑汁建造起来的多层环状结构也将大不适应。中心化城市的各种弊端，诸如交通堵塞、人口拥挤、环境污染、空气浑浊、疾病易于传播、犯罪案件增多、居住环境恶化、管理难度增加和公众空间锐减等，限制了城市的进一步发展。而现代高科技可以自由地用虚拟空间、网络空间取代地理空间或物理空间，因此，人们也就没有必要再拥挤在一个地域。于是自然而然就开始了从市区向市郊的转移，许多工厂、学校、研究机构都迁向市郊。市区再也没有工厂和生产基地，而变成纯粹的物质交换和消费的场所。又由于信息技术、网络技术、电信技术的发展，中心化城市的传统布局被彻底打散。
现在世界各地迅速崛起许多边缘城市，就属于中心化城市的后现代演变。中心化城市逐渐演变为主城市和边缘城市。主城市和边缘城市相互联系、相互作用而又各自独立，它们更多的是经济、文化和教育上的紧密联系。城市的边缘化，就是城市由中心向四周的蔓延与扩展，扩展到与非城市区域相接壤的既是城市又是乡村的地区。这里，现代商业交易和办公活动也走向郊区化、边缘化。生产规模、生产程序、劳动力市场和销售状况呈分散状。主城市与边缘城市通过铁道、地铁、高速公路、航空路线等组成的多模式运输系统以及卫星天线进行沟通。
这种城市的边缘化在许多发达国家已经形成规模，比如今天的美国就已经形成大洛杉矶都市区以及波士顿—劳伦斯—洛厄尔、旧金山—奥克兰—圣何塞等都市区。它们还会进一步向周边地区扩展，通过原料网、生产网、销售网、消费网、信息网和电脑网的连接而延伸到整个地球，成为[ ]的全球化城市。

根据原文提供的信息，下列推断正确的一项是( )。

A．在枝蔓状的城市布局中，主城市和边缘城市的差别将趋于消失

B．铲除中心化城市的诸多弊端有待于城市的后现代演变

C．在枝蔓状城市中，人们受地理空间或物理空间的限制将越来越少

D．随着中心化城市的边缘化，生产地域化和劳动力低廉化将成为现实
