为什么教育不能产业化教育究竟能不能产业化?教育的确在一定程度上具有与私人产品相同的属性，比如这种产品的消费也具有一定的竞争性、排他性，并且，受教育者可以通过教育得益，例如增加工资收入、提高社会地位、获得精神享受等，其教育花费也就等同于私人的一种投资。
从这个意义上讲，教育具有商品属性，可以定价，可以买卖。
但是，教育同时具有公共产品的基本属性——社会公益性。
受教育者通过教育可以获得个人的种种直接收益，但受过良好教育的公民无疑可以给全社会带来广泛的收益，包括生产力的提高、社会文明程度的进步等等。
正因教育消费有溢出效应，也就是公益性，所以，经济学把教育定义为“准公共产品"，而不是私人产品。
这早已成为世界性的共识，成为世界所有国家主要由政府举办教育事业的最重要的理论根基。
1 999年10月联合国教科文组织在巴黎召开了首次世界教育大会，大会一致认为“市场规律和竞争法则不适用于教育。
教育不是经济的一个分支。
教育过程、教育目标、教育结果或t教育产品'都不能与经济相提并论"。

Lucky loved to find ways to leave the confines (束缚) of her indoor living routine, which made her a masterful escape artist. Lily Bit, on the other hand, did exactly as she was told, never straying, always staying close to home... except when she came under the influence of Lucky.Whenever the two got out together, they could be seen out of sights often staying away for hours. More often than not, they’d arrive home near suppertime, covered in mud and leaves and smelling to high heaven from their afternoon outing in the woods.I remember one such occasion w hen they’d once again mysteriously escaped, except this time, they returned clean and no worse for wear. It wasn’t until a few days later that we learned why. My wife ran into our neighbor Carl who lived a few houses down from us.“I saw your two dogs the other day,” Carl said with a smile,“Oh, yes? I’m so sorry. They’d been so good lately, so it was such a surprise when they got out. I sure hope they didn’t cause any trouble.” my wife replied,“Oh, no, no trouble at all. Did you have any idea where they went?”“No,” my wife answered.“They attended my dog’s funeral (葬礼)” Carl said sadly.“What?” Ann exclaimed, “Oh, no. I didn’t know Toby had died.“Yep, it died a couple days ago. I was burying him in the back lot when your two dogs came running up. They sa t down not far from me while. I finished burying him, then they left.”“Wow that’s amazing! ” my wife replied. “Toby was Lily Bit’s father, you know. ”“No, I didn’t know that,” Carl replied, “but I guess that explains why she felt like she needed to be th ere.

Blind since birth, the Turkish man was struggling to find his hotel, holding a cane in one hand and pulling his luggage with the other.“Not surprisingly, all of a sudden I bumped into a pole,” he says. “It was a little bit bloody.”The problem with a cane is that, while it can tell you what's on the grounds it doesn't help with objects at the body or head level. It wasn't the first time Ceylan had run into something,injuring himself.“I have no problem with my scars, they make me more handsome I guess,” Ceylan says, laughing. “But I don’t need new ones.”With WeWalk, a new smart cane, Ceylan hopes to help other blind people navigate their environments more easily. The cane uses an ultrasonic(超声波)sensor which detects objects at body or head level and gives a warning vibration. WeWalk users pair the cane with their smartphones and then use the cane's touchpad to access features like voice assistant or navigation. Before leaving home, they can plug their destination into Google Maps and get spoken directions as they walk. In the future, Ceylan hopes to connect WeWalk with public transportation and ridesharing services.The GPS- and voice technology-enabled cane can tell users what’s around them—they’re passing a McDonald’s, they’re at Exit D of the subway station. An ultrasonic sensor detects objects at body or head level and gives a warning vibration.Assistive technology is often expensive for blind people, says Eelke Folmer, a computer science professor at the University of Nevada! Reno. But developers fail to realize their devices are out of reach for many blind people. To Folmer, the price point—$500——sets the WeWalk cane apart from other technologies.Ceylan sees WeWalk as part of an attempt to help blind people achieve greater freedom of movement, which he believes will give them greater access to education and jobs. The canes are already having an impact on users, Ceylan says. He recently received an email from a teacher in Ireland who had become blind as an adult. He'd been depressed and housebound. But since getting a WeWalk cane, “your device forced me to go out. It became my anti- depressant. ” he wrote.8．Why is a story about Kursat Ceylan given at the beginning of the text?A．To stress the difficulty caused by blindness.B．To show his reason for developing his cane.C．To indicate the problems with present canes.D．To show his positive and humorous character.9．What can WeWalk do at present according to the text?A．Provide fast Internet access. B．Start conversations with users.C．Tell users what is around them. D．Connect with ridesharing services. 10．What does Folmer think is the advantage of WeWalk over other assistive technologies?A．It is easily affordable, B．It is easily controllable.C．It works better for users, D．It looks more attractive.11．What is the text mainly about?A．The increasing demand for smart canes.B．A blind man’ s devotion to smart canes.C．A smart cane’s effects on blind people.D．An assistive technology for the blind.When you think of a national park, you generally picture fresh air and wild animals, right? Well, now you're going to have to add tea shops and something called "the Tube" to your definition, because London, England has signed up to be the first "National Park City."London was established by the Romans around 2,000 years ago and has been continually inhabited (居住于) since then. In all that time, however, nobody had the idea to replace all the parks with big box stores or high buildings, which means London already has a much lower urban density (密度)than most of the worlds cities. Nowadays about a third of the city is green space,In July 2019, London announced its willingness to become the world’s first National Park City. Now the city is moving toward the goal of achieving 50% green space by the year 2050 by connecting and expanding public parks, greening up unused parking lots and the private yards of existing and new houses, fixing some green roofs on existing buildings and even cutting holes in fences for wildlife to pass through."Inspired by the aims and values of our precious rural national parks, the London National Park City is basically about making life better in the capital through both small everyday things and long-term strategic thinking," Daniel Raven-Ellison, who began the campaign to make London a National Park City six years ago said in a press release. "We've been doing that in London for centuries, which is why London is so green and diverse. "London will have a much easier job achieving this type of green transformation than more densely-urbanized cities like Paris and New York, which have 10% and 27% greenspace, respectively. But that doesn't mean it's not possible——the National Park City Foundation hopes to employ 25 more cities in addition to London by the year 2025. Glasgow, Scotland and Newcastle upon Tyne in northeast England are both currently considering becoming National Park Cities.12．What makes London more likely to become a national park city than other cities? A．Its smaller population. B．The government’s efforts.C．Its less dense urbanization, D．Its citizens’ great support.13．Where can we find the data on London’s measures to achieve its goal?A．In Paragraph 1. B．In Paragraph 2.C．In Paragraph 3. D．In Paragraph 4.14．What is Daniel Raven-Ellison trying to talk about in the fourth paragraph? A．London’s long-term strategic thinking.B．The significance of London’s campaign.C．The effects of national parks on London.D．The resources of London’s green space.15．What can we infer from the last paragraph?A．Trying to be a national park city is turning new trend.B．National park cities are springing up around the world.C．It is so easy for London to become a national park city.D．National park cities are making improvements to our life.二、完形填空When I was growing up, there was a pizza shop right down the street from me, The pizza shop was 16 by a Chinese woman who opened the place around 11:00 a. m. and closed it around midnight every day.
