Breakthroughs in science and technology are paving the way for modern cities to support bigger populations. Now, we see the most exciting urban innovations to show you exactly how they'll improve your city's infrastructure(基础设施).

Lighting Up The Night

    Anthony Di Mari dreamed up an electric tree to help irrigate public parks and light them at night. These electric trees contain a special infill (填充物) that collects water from rainfall. The water is then distributed through a shallow underground irrigation system with the help from the trees' swaying movement. An electric motor turns energy from the waving of the artificial trees into electricity, which is used to light up the trees' outer LEDs.

Thinking Outside The Box

    As more people flock to urban areas, city planners will need to get increasingly creative about how to satisfy residents' health and transportation needs within decreasing available space. One way to achieve this is by updating infrastructure to support biking and walking by building suspended(悬浮的) roundabouts like hovering in the Netherlands. By lifting bicycle and pedestrian traffic above busy roadways, cities can significantly decrease over-crowded traffic condition.

Waving Hello To Clean Energy

    Cities that don't receive enough sunlight may find an attractive alternative in wave power. Since ocean waves rarely experience disruption(中断), electric engines driven by their clockwork push-and-pull can reliably provide power throughout the year. Further, thanks to advances in wave power technology, engineers have been able to move wave power engines farther offshore, where the waves pack the most punch, making the engines extremely efficient. So in the future, heavily populated coastal cities may use wave to meet their energy needs.

    Your school asked parents about the social development in children in the last Parents' Meeting. Here are some opinions. Read the following information and answer the questions.

    Minutes after the last movie ended yesterday at the Plaza Theater, employees were busy sweeping up popcorns and gathering coke cups. It was a scene that had been repeated many times in the theater's 75-year history. This time, however, the cleanup was a little different. As one group of workers carried out the rubbish, another group began removing seats and other theater equipment in preparation for the building's end.

    The film classic The Last Picture Show was the last movie shown in the old theater. Though the movie is 30 years old, most of the 250 seats were filled with teary-eyed audience wanting to say good-bye to the old building. Theater owner Ed Bradford said he chose the movie because it seemed proper. The movie is set in a small town where the only movie theater is preparing to close down.

    Bradford said that large modem theaters in the city made it impossible for the Plaza to compete. He added that the theater's location (位置) was also a reason. “This used to be the center of town,” he said. “Now the area is mostly office buildings and warehouses.”

    Last week some city officials suggested the city might be interested in turning the old theater into a museum and public meeting place. However, these plans were given up because of financial problems. Bradford sold the building and land to a local development firm, which plans to build a shopping complex on the land where the theater is located.

    The theater audience said good-bye as Bradford locked the doors for the last time. After 75 years the Plaza Theater has shown its last movie. The theater will be missed.

    English teenagers will receive cooking lessons in schools. The idea is to encourage healthy eating to solve the problem that many people are overweight. Also, it worries people that basic cooking and food preparation skills are being lost because parents use too much pre-prepared fast food.

Cooking was once regarded as an important part of education in England—even if it was mainly for girls. In recent years cooking has become less important in schools. But the rising level of obesity has led to rethink about the food that children are given and the skills they should be taught.

    “What we want is to teach young people how to do basic, simple meals, which they can use now at home and then in their life,” said Ed Balls, an education expert.

    The new lessons will start in September, but some schools without kitchens will be given a longer time to prepare. Also, there may be a shortage of teachers with the right skills, since schools have been teaching food technology rather than practical cooking. Besides, the lessons for hand-on cooking will only be one hour a week for one term. But the well-known cookery writer, Pru Leith, believe it will be worth it.

    “If we'd done this thirty years ago we might not have to face the problem about obesity and lack of knowledge about food and so on. Every child should know how to cook, not just so that they'll be healthy, but because it's a life skill which is a real pleasure.”

    The renewed interest in cooking is an effort to reduce the obesity rate, which is almost the highest in Europe, and according to the government, half of all British people will be obese in 25 years if present trends are not halted.

The Secret Life of Foxes

Have you ever spotted a fox on the streets of your town at night or even in your back garden? Wildlife enthusiasts will love finding out more about the mysterious lives of foxes. As well as lots of interesting information, this book includes great ideas for ways to help foxes near you. 

PleaseDonˈt Bite Me

by Nazzy Pakpour.

Illustrated by Owen Davey

Did you know that wasps can build nests as much as five metres wide? Or that fleas can jump 150 times their own height? How do mosquitoes track you down? This interesting illustrated book digs out the surprising lives of some of the buzzing, biting and stinging insects that are all around. 

Stone Age Beasts

by BenLerwill.

Illustrated by Grahame Baker-Smith

Travel back in time to meet incredible creatures in this beautiful book. It features many of the prehistoric animals that our human ancestors would have met face-to-face in the Stone Age. Learn about the woolly mammoth, the sabre-toothed cat, and the six-metre snake that once slithered along the forest floor. 

The hens look up at me from their nesting boxes. They seem slightly annoyed but unsurprised. A child runs up, pushes one of the chickens aside, and snatches two eggs. Around me, a half-dozen more children and adults collect eggs while a half-dozen others hand-feed dried mealworms to birds flocking around our ankles. I reach for an egg from an empty nest. There is something perfect about the way it fits warmly in the palm of my hand before I transfer it into a pretty wire basket provided to me by my hosts. 

The egg harvest is a brief, carefully designed agritourism experience offering an experience of the labor rather than just having a bite of food. Snatching a few eggs and uprooting a few vegetables on the farm tour donˈt constitute a full dayˈs work, but it is also a useful reminder that food doesnˈt just magically appear on restaurant plates and grocery store shelves. Of course, visitors can take those eggs home or bring them to the on-farm restaurant, Clay, where a chef will use them to prepare breakfast. 

A few centuries of industrialization, urbanization, and globalization have collected people into cities, but the attraction of the countryside has always remained. In the new urban-centered world, enterprising farmers have found plenty of opportunities to sell their rural lifestyle along with their crops. Italy promoted the modern model for combining agriculture and tourism in the wake of World War Ⅱ, when the national government encouraged rural populations to continue producing food rather than move to urban areas in search of more profitable jobs. 

Agritourism acts as an umbrella term for a wide variety of activities that take place on farms, including farmstays, where guests sleep on-site. For varying investments of time, energy, and money, anyone can engage in our farming system, giving consumers a peek behind the farm-to-table world.
